Sally Leadfoot was pulled over on her way from Syracuse to Ithaca by an officer claiming she was speeding. The speed limit is 65 mph and Sally has traveled 97 km in 102 minutes. How fast was Sally's average speed in mph? In a complete sentence, explain whether or not Sally deserves a ticket?

To isolate the variable in x + 5 = -12, subtract 5 from both sides of the equation. This leads to the equation x = -12 - 5.

In order to isolate the variable x in the equation x + 5 = -12, you should subtract 5 from both sides of the equation. This gives us the equation in a simplified form that allows us to determine the value of x. The idea here is to cancel out the +5 on the left side by subtracting 5 from both sides, resulting in x = -12 - 5. Hence, the answer is option b.

To solve this problem, we use the tan function. The distance across the river is the adjacent side, the distance drownstream is the opposite side while the direction of the boat is the hypotenuse.

tan θ = opposite side / adjacent side

tan 10 = opposite side / 420 ft

opposite side = 74.06 ft

Therefore the boat will move about 74 ft downstream.

Answer with Step-by-step explanation:

A scale model of a school building is 5 inches tall.

Actual size of the school building is 100 feet.

1 feet=12 inches

100 feet=12×100 inches

             = 1200 inches

5 inch is representing 1200 inches

1 inch represents  1200/5 inches

1 inch represents  240 inches

or  1 inch represents  12×20 inch

or 1 inch represents 20 feet

Scale of the model is:

1 inch represents  240 inches

1 inch represents 20 feet

The probability that the first number is a 3 and the second is a 7 is 1/64

It is a branch of mathematics that deals with the occurrence of a random event.

Given:

spinner had region numbered from 1 to 8

So, the probability on the spinner has an equally likely chance of being selected= 1/8.

P(3) = 1/8

P(7) = 1/8

Thus, probability that the first number is a 3 and the second is a 7

=(1/8) * (1/8)

= 1/64

Answer:

The answer is D.

Step-by-step explanation:

We know this because it is an "and" problem because it is numbers in between, not outside.

We also know it is "no less" or "no more" than 50 or 100. so we use a less than and equal too. Not just a less than sign.

Really hoped this helped, kind of in a test right now so just giving a brief way of how to figure this stuff out.

The required pair of number are -3 and -6

The factored form of the trinomial is (x-3) and (x-6)

The standard form of a quadratic equation is expressed as:

[tex]ax^2+bx+c=0[/tex]

Given the expression [tex]x^2 - 9x + 18.[/tex]

[tex]a=1\\b=-9\\c=18[/tex]

We are to get two values that we must add to get b, and that we will multiply that will give c.

The given values are -6 and -3

Check:

[tex]-6+(-3)=-6-3=-9\\-6(-3) = 18[/tex]

Factorize the trinomial

[tex]x^2-9x+18\\x^2-6x-3x+18\\x(x-6)-3(x-6)\\(x-3)(x-6)[/tex]

Answer:

Option C is correct

The expression [tex](1215)^{\frac{1}{5}x}[/tex]  is equivalent to [tex]\sqrt[5]{1215^x}[/tex]

Step-by-step explanation:

Simplify the radical Expression: [tex]\sqrt[5]{1215^x}[/tex]

A radical expression can be written by using the exponents and also using the following procedure:

[tex]\sqrt[n]{x} = x^{\frac{1}{n}}[/tex]

when x be non-negative then n can be any index

when x is negative, then n can be odd.

The following radical expression can be written as:

[tex]\sqrt[5]{1215^x} = (1215^x)^{\frac{1}{5}}[/tex] = [tex](1215)^{\frac{1}{5}x}[/tex]

Therefore, the expression [tex](1215)^{\frac{1}{5}x}[/tex]  is equivalent to [tex]\sqrt[5]{1215^x}[/tex]

Answer-

In picture 4, the triangle is reflected over x axis.

Solution-

While reflecting a point over x axis, (x, y) → (x, -y) rule is followed.

Only the sign of y-coordinate is changed, keeping x-coordinate intact.

In the first picture, though the image is reflected, but it is reflected over y axis.

In the second picture, the image is first reflected over y axis, then it is translated 1 unit down.

We rotating a point 90° clockwise, (x, y) → (y. -x) rule is followed.

In the third picture, the triangle is rotated 90° clockwise and then translated 1 unit to right.

But, in case of the fourth picture, the figure is reflected over x axis. Only the y coordinates sign are changed, all the x coordinates are same as before.

Answer:

Answers a little bit more simplified, all credit to the expert :)

E(4, 4), F(8, 3), G(10, 6) and H(8, 6) <-----> a translation 7 units right

E(3, 4), F(-1, 3), G(-3, 6), and H(-1, 6) <-----> a reflection across the y-axis

E(-3, -1), F(1, -2), G(3, 1), and H(1, 1) <-----> a reflection across the x-axis

E(-3, -1), F(1, -2), G(3, 1) and H(1, 1) <-----> a translation 5 units down

Step-by-step explanation:

The system of equations are 3y − x = −6 and 4y − x = 4

Two or more expressions with an Equal sign is called as Equation.

One third x − 2 = one fourth x + 11

1/3x - 2 = 1/4x + 11

Now let us take y as 1/3x - 2

y= 1/3x - 2

3y=x-6

Subtract x on both sides

3y-x=-6

and Let us consider the right side equation

y=1/4x + 11

4y=x+44

Subtract x on both sides

4y-x=44

Hence, the system of equations are 3y − x = −6 and 4y − x = 44

One of either the circumference or distance across is not rational. If you have a bit of string precisely 1 inch long and you make it into an idealize circle, the distance across of that circle will be an irrational value. You could try to measure it, however regardless of how precisely you measured it, it would in any case not be very sufficiently precise. So, you can never know precisely what the diameter is just by measuring.

What's more, on the off chance that you took that string and made a width with it, the circumference would be irrational and you could never have the capacity to measure the circumference precisely enough. Whatever you quantified would be close however not correct.

Step-by-step explanation:

Fiona should use 1 cup of butter when using 3 cups of flour, according to the recipe's ratio of 24:8:3 for flour to butter to water.

The question asks how much butter Fiona should use if she's using 3 cups of flour and the recipe calls for flour, butter, and water in the ratio of 24:8:3. To solve this, we take the ratio for butter (which is 8) and divide it by the flour ratio (which is 24), then multiply by the number of cups of flour Fiona is using (which is 3 cups).

negative 5 plus or minus the square root of 17 divided by two: [tex]x=\frac{-5\pm\sqrt{17}}{2}[/tex].

Step-by-step explanation:

We have the equation

[tex]x^2+5x=-2[/tex]

[tex]x^2+5x+2=0[/tex].

To solve it, we are going to use the general formula. This formula is used to find the solutions of quadratic equations.

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

where a is the coefficient of [tex]x^2[/tex], in this case a=1, b is the coefficient of x, in this case b=5 and c is the independent term, in this case c=2.

[tex]x=\frac{-5\pm\sqrt{5^2-4(1)(2)}}{2(1)}[/tex]

[tex]x=\frac{-5\pm\sqrt{25-8}}{2}[/tex]
