To solve the equation 1 3/5(t-6)=-0.4, first distribute 1 3/5 to the terms inside the parentheses. Then, multiply both sides of the equation by the reciprocal of 8/5 to isolate the variable t. Finally, simplify the equation to find the solution t = 5.75.

To solve the equation 1 3/5(t-6)=-0.4, we can follow these steps:

Therefore, the solution to the equation is t = 5.75.

Final answer:

To solve the equation 1 3/5(t-6)=-0.4, distribute the 1 3/5 first and then simplify the equation by adding and subtracting terms to isolate t. The final solution is t = 2.

Explanation:

To solve the equation 1 3/5(t-6)=-0.4, we can begin by distributing the 1 3/5 to the terms inside the parentheses:

1 3/5(t-6) = 1 3/5 * t - 1 3/5 * 6 = 8/5t - 18/5

Now, we can rewrite the equation as:

8/5t - 18/5 = -0.4

Next, we can get rid of the fraction by multiplying both sides of the equation by 5:

5(8/5t - 18/5) = 5(-0.4)

After simplifying, we get:

8t - 18 = -2

Now, add 18 to both sides of the equation:

8t - 18 + 18 = -2 + 18

Simplifying further, we have:

8t = 16

Finally, divide both sides of the equation by 8 to solve for t:

t = 16/8

Therefore, the solution to the equation is t = 2.

Answer:

Choice C is correct

Step-by-step explanation:

We use the law of exponents in this problem;

[tex](a^{b})^{2}=a^{b}*a^{b}[/tex]

Therefore,

[tex](9^{\frac{1}{2} })^{2}=9^{\frac{1}{2} }*9^{\frac{1}{2} }[/tex]

Since the base is the same, that is 9, we simply add the exponents 1/2;

[tex]9^{\frac{1}{2}+\frac{1}{2} }[/tex]

one-half plus one-half is equal to unity and any number raised to one is simply equal to the given number;

[tex]9^{1}=9[/tex]

Answer:

an = 5 + 2n

Step-by-step explanation:

Each time it increases by the same amount (2), so this is an arithmetic sequence:

an = a₁ + d (n - 1)

Given a₁ = 7 and d = 2:

an = 7 + 2 (n - 1)

an = 7 + 2n - 2

an = 5 + 2n

Check our answer:

n=1: a₁ = 5 + 2(1) = 7

n=2: a₂ = 5 + 2(2) = 9

n=3: a₃ = 5 + 2(3) = 11

n=4: a₄ = 5 + 2(4) = 13

The pattern represents the arithmetic progression and the explicit formula for the nth term is a(n) = 2n + 5

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have a sequence:

7, 9, 11, 13…

The above pattern represents the arithmetic progression.

The first term a = 7

Common difference d = 2

nth term:

a(n) = 7 + (n - 1)(2)

a(n) = 2n + 5

Thus, the pattern represents the arithmetic progression and the explicit formula for the nth term is a(n) = 2n + 5

Answer:

(I'm guessing the question is asking how much money Brady needs to pay.)

Step-by-step explanation:

21-5

(the original amount minus the 5 gallons he already has)

= 16.

so Brady needs 16 gallons.

and every gallon is 1.4

so 16 * 1.4

= 22.40

So brady needs 22.40 dollars.

The total cost of 16 gallons of gas is $22.4.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, 21 miles per gallon for gas mileage.

When he stops at the gas station, he already has 5 gallons of gas in his tank.

So, 21-5=16 miles

He buys gas for $1.40 per gallon

Now, total cost = 16×1.40

= $22.4

Therefore, the total cost of gas is $22.4.

Answer:

Ratio.

Step-by-step explanation:

A logarithmic function is an appropriate model because, for evenly spaced y-values, the ratio of consecutive x-values is constant. This is the correct answer to your question.

Hope this helps!!!

Kyle.

Answer:

Step-by-step explanation:

Whenever a function is logarithmic function, we get for evenly spaced y,

say y = log x

     y+d = log x1

     y+2d = log x2

We get

d = [tex]log \frac{x_1}{x} =log \frac{x_2}{x_1}[/tex]

In other words we get the ratios of consecutive x values is constant equal to the difference in consecutive y's.

Answer:

(3, 2)

Step-by-step explanation:

Given a graphical representation of a system of equation then the solution is at the point of intersection of the 2 lines, that is

solution is ( 3, 2)

Answer:

$90, $135, $189

Step-by-step explanation:

Since the first part of the ratio is two- thirds of the second, then

first part = [tex]\frac{2}{3}[/tex] × 5 = [tex]\frac{10}{3}[/tex]

The ratio is then

[tex]\frac{10}{3}[/tex] : 5 : 7

Sum the 3 parts of the ratio

[tex]\frac{10}{3}[/tex] + 5 + 7 = [tex]\frac{46}{3}[/tex]

Divide the amount to be shared by the sum to find the value of one part of the ratio.

$414 × [tex]\frac{3}{46}[/tex] = $27 ← value of 1 part of the ratio, then

[tex]\frac{10}{3}[/tex] × $27 = $90

5 × $27 = $135

7 × $27 = $189

The 3 parts are $90, $135, $189

Answer:

Step-by-step explanation:

You want an expression representing the cash flow of a taxi driver after giving three rides, filling the gas tank, then giving one more ride.

At $3.50 per mile, the driver will have income that is $3.50 multiplied by the number of miles for the ride. These income amounts are added.

A payment of $50 for gas is subtracted from the driver's income.

The desired expression is ...

  3.50×10 +3.50×5.5 +3.50×19 -50 +3.50×26

The value of the expression is $161.75.

The driver had $161.75 after the last ride.

Answer:

It would take 4 men 37 hrs and 12 mins to complete the same task.

step-by-step explanation:

Let X be the time the four men would use to complete the task.

From the question, 6 men completed a task in 24 hrs and 48 mins

But

[tex]24 \: hrs \: 48 \: mins = 24(60mins) + 48 \: mins=1488 \: mins[/tex]

Using ratio and proportion

[tex]6 \: men:1488 \: mins[/tex]

[tex]4 men:x\:mins[/tex]

if more, less divides and if less, more divides.

4 men required more time to complete the task

Hence:

[tex]x = \frac{6}{4} \times 1488 \: mins[/tex]

[tex]x = 2232 \: mins[/tex]

x = 37 hrs 12 mins

To solve the inequality -1.6 < m/-2.5, we multiply both sides by -2.5 and reverse the inequality sign, resulting in m being less than 4. This solution can be graphed on a number line with an open circle at 4 and shading to the left.

To solve the inequality -1.6 < m/-2.5, we need to manipulate the inequality to isolate the variable m.

First, multiply both sides of the inequality by -2.5 to get m by itself. Remember, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol. So:

To graph this solution, draw a number line and make an open circle at 4, indicating that 4 is not included in the solution. Then, shade everything to the left of 4 to represent all the numbers that are less than 4.

Solve for x

That means-----> isolate the variable x

squared both sides

[tex]L^{2} =(\frac{1} {\sqrt{x^2-6x + 5}})^{2}\\ \\L^{2}=\frac{1} {{x^2-6x + 5}}\\ \\x^2-6x + 5=\frac{1}{L^{2}}\\ \\x^2-6x=\frac{1}{L^{2}}-5\\ \\x^2-6x+9=\frac{1}{L^{2}}-5 +9\\ \\x^2-6x+9=\frac{1}{L^{2}}+4\\ \\(x-3)^2=\frac{4L^{2}+1}{L^{2}}[/tex]

Answer:

Step-by-step explanation:

I think this is the answer X = 3 + 1/2y

The solutions for the system of equations are:

[tex]\[ (x, y) = (\sqrt{6}, 0), (-\sqrt{6}, 0), (\sqrt{5}, -1), (-\sqrt{5}, -1) \][/tex]

To solve the system of equations[tex]\(x^2 + y^2 = 6\)[/tex] and [tex]\(x^2 - y = 6\)[/tex], we can use substitution or elimination method. Let's solve it using the substitution method:

Given equations:

1.[tex]\(x^2 + y^2 = 6\)[/tex]

2.[tex]\(x^2 - y = 6\)[/tex]

From equation 2, we can express [tex]\(x^2\) as \(y + 6\):[/tex]

[tex]\[x^2 = y + 6\][/tex]

Now, substitute [tex]\(x^2 = y + 6\)[/tex] into equation 1:

[tex]\[y + 6 + y^2 = 6\][/tex]

Rearrange this equation:

[tex]\[y^2 + y + 6 = 6\][/tex]

Subtract 6 from both sides:

\[y^2 + y = 0\][tex]\[y^2 + y + 6 = 6\][/tex]

Factor out y:

[tex]\[y(y + 1) = 0\][/tex]

So, either [tex]\(y = 0\)[/tex] or [tex]\(y + 1 = 0\)[/tex] , which means[tex]\(y = 0\)[/tex]  or [tex]\(y = -1\).[/tex]

Now, substitute these values of y back into equation 2 to find the corresponding values of x.

For [tex]\(y = 0\):[/tex]

[tex]\[x^2 - 0 = 6\][/tex]

[tex]\[x^2 = 6\][/tex]

[tex]\[x = \pm \sqrt{6}\][/tex]

For [tex]\(y = -1\):[/tex]

[tex]\[x^2 - (-1) = 6\][/tex]

[tex]\[x^2 + 1 = 6\][/tex]

[tex]\[x^2 = 5\][/tex]

[tex]\[x^2 = 5\][/tex]

So, the solutions for the system of equations are:

[tex]\[ (x, y) = (\sqrt{6}, 0), (-\sqrt{6}, 0), (\sqrt{5}, -1), (-\sqrt{5}, -1) \][/tex]

The system has four solutions: [tex]\((\sqrt{6}, 0)\), \((- \sqrt{6}, 0)\), \((\sqrt{5}, -1)\), and \((- \sqrt{5}, -1)\).[/tex]

The eggs are approximately 2.1 and which each turtle does not lay 113 they lay 123 eggs each year around which you subtract it all up and it comes out to 120.9.then the you divide all up which gives you your answer to your problem.

Final answer:

The volume of one spherical green turtle egg with a diameter of 4.1 cm is approximately 36.2 cubic centimeters. The total volume of 113 such eggs is about 4091.6 cubic centimeters when rounded to the nearest tenth.

Explanation:

To calculate the volume of one green turtle egg, we use the formula for the volume of a sphere, which is V = 4/3 πr³, where r is the radius of the sphere. Since the egg has a diameter of 4.1 centimeters, the radius is half of that, which is 2.05 centimeters. Plugging this value into the formula gives us V = 4/3 π(2.05 cm)³ ≈ 36.2 cubic centimeters when rounded to the nearest tenth.

Next, we calculate the total volume of eggs laid by one turtle. Since each turtle lays 113 eggs, the total volume is 113 × 36.2 cm³ = 4091.6 cm³, which rounds to 4091.6 cubic centimeters.

Hence, In 250 hours 143 seats can be assembled. (Round to nearest whole number)

The product could be either less than or greater than 67,124.

If you multiplied by a negative number, you would get a negative number, which is less than a positive number such as 67,124.

If you multiplied by zero, you would get zero, which is less than a positive number such as 67,124.

If you multiplied by one, you would get 67,124, which is equal to 67,124 since they are the same number.

If you multiplied by a positive number less than one, you would get a positive number greater than zero and less than 67,124.

If you multiplied by a positive number greater than one, you would get a positive number greater than 67,124.
