Answer:

16 cups

Step-by-step explanation:

64 × .25=16

When the total amount of ice cream, 64 cups, is divided by the scoop size, which is 1/4 cup, it gives us 256. Therefore, Jerry can get 256 scoops of ice cream from each bucket.

The amount of ice cream in each bucket is given as 64 cups. Jerry's scoop holds 1/4 cup of ice cream. In order to figure out how many scoops Jerry can get from one bucket, we need to divide the total amount of ice cream (64 cups) by the amount Jerry's scoop holds (1/4 cup).

To carry out this operation, we divide 64 by 1/4 which is equivalent to multiplying 64 by the reciprocal of 1/4 (i.e., 4/1 or simply 4). This results in 64 * 4 = 256. So, Jerry can get 256 scoops of ice cream out of each bucket.

Answer: 40 small cups sold and 30 large cups sold.

Step-by-step explanation:

Let be "s" the number of small cups sold and "l" the number of large cups sold.

Based on the information given in the exercise, you can set up the following system of equations:

[tex]\left \{ {{s+l=70} \atop {10s+20l=1000 }} \right.[/tex]

You can use the Elimination Method to solve the system of equations:

1. Multiply the first equation by -10.

2. Add both equations.

3. Solve for "l".

Then, you get:

[tex]\left \{ {{-10s-10l=-700} \atop {10s+20l=1000 }} \right.\\.........................\\10l=300\\\\l=\frac{300}{10}\\\\l=30[/tex]

4. Finally, substitute the value of "l" into any original equation and solve for the variable "s" in order to find its value.

This is:

[tex]s+30=70\\\\s=70-30\\\\s=40[/tex]

Answer:

Step-by-step explanation:

the average can be found by adding up all ur numbers and dividing by how many numbers u have

so her average test score is : (88 + 80) / 2 = 168/2 = 84 <==

To find Maddie's average test score, add up her scores (88+80=168) and divide by the number of tests (2). This gives us an average of 84.

The subject of this question is Mathematics, specifically the concept of calculating averages. To calculate Maddie's average test score, you'll need to add up the scores she received and then divide the sum by the number of tests she took.

In this case, Maddie earned an 88 on her first test and an 80 on her second test. You would add these two scores together (168), then divide by 2 (since she took 2 tests), which gives us an average of 84.

So, Maddie's average test score is 84.

Answer:

Step-by-step explanation:

Answer:

OPTION B:   229.28 $

Step by-step explanation:

Whenever a deposit is made the balance increases and when a withdrawal is made the balance is decreased.

So, to compute the balance on Friday, assuming that he hasn't deposited on Friday, we add all the deposits and subtract all the withdrawals.

On Monday he has 225 $. He withdraws 27.25 $. So, the balance would be: 225 - 27.25 = 197.75

On Tuesday he deposits money. So, the balance would be 197.75 + 75.5

= 273.25

On Wednesday he deposits and withdraws. So, it would be

273.25 + 32.19 - 61 . 95 = 243.49

On Thursday, he withdraws. So, the balance would be: 243.49 - 14.21

= 229.28 $ which will be the balance on Friday.

Hence, OPTION B is the answer.

We expand the parenthesis to get:

[tex]14 - 28t -35 - 70t[/tex]

We group like terms to get:

[tex]14 -35 - 28t- 70t[/tex]

We combine similar terms to get:

Answer:

3n + 5

Step-by-step explanation:

You can't add 5 to 3n. So in 5 years he will 3n + 5.

José's age in 5 years will be 3n + 5, where 3n represents his current age.

If José's present age is 3n, and we want to find out how old he will be in 5 years, we need to add 5 to his current age expressed as 3n. This can be done with a simple algebraic expression:

Age in 5 years = Current Age + 5 = 3n + 5

Without the value of n, we can't calculate his exact future age, but we know that in 5 years, his age will be 5 years older than it is now.

Answer:

P(red marble) = 6÷15

Step-by-step explanation:

First, we add all of it we get 15.

Now the probability of getting a red marble will be = number of favorable outcomes ÷ total out comes.

Here the favorable outcomes to red is 6,and the total outcome is 15.

So it is 6÷15.

Now we took one marble. And kept it away.

Now the total number of outcomes are 15-1=14

Now the favorable outcomes for green is 7,snd total outcomes are 14.

So the probability is 7÷14.

Remember don't subtract the one marble u took in every similar question. Do it only if it is told to keep away the first marble you took.

y intercept is 4

Step-by-step explanation:

rearranging the equation,

Answer:

Step-by-step explanation:

31) Y = -3x² + 18 x -25 = -3*x² + -3*-6x -25

  = -3(x² -6x) - 25

( (a-b)² =a² - 2ab + b²;   here a = x; 2ab = -6x = -2*x*3; and so b = 3)

  = -3(x² -6x + 9 - 9) - 25  

 { when we add and subtract 9, the equation will not change}

= -3[(x -3)² - 9] -25

= -3(x - 3)² - (-3)*9 - 25

= -3(x - 3)² + 27 -25

= -3(x - 3)² + 2

32) y= -3x² - 18x - 25

    = -3 (x² + 6x )-25

  = -3 (x² + 6x + 9 - 9) -25

= -3 [ (x+ 3)² - 9] -25

=-3 (x + 3)² - (-3)*9 - 25

= -3(x + 3)² + 27 - 25

= -3(x+3)² +2

5 jars of jam and 3 packages of bread mix are in gift basket

Solution:

Let "x" be the number of jars of jam

Let "y" the number of packages of bread mix

Cost of 1 jars of jam = $ 6

Cost of 1 package of bead mix = $ 5

There are 8 items in the basket

Therefore,

number of jars of jam + number of packages of bread mix = 8

x + y = 8 ---------- eqn 1

A gift basket that contains jars of jam and packages of bread mix costs $45

Therefore, we frame a equation as:

number of jars of jam x Cost of 1 jars of jam + number of packages of bread mix x Cost of 1 package of bead mix = 45

[tex]x \times 6 + y \times 5 = 45[/tex]

6x + 5y = 45 --------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

x = 8 - y --------- eqn 3

Substitute eqn 3 in eqn 2

6(8 - y) + 5y = 45

48 - 6y + 5y = 45

y = 48 - 45

Substitute y = 3 in eqn 3

x = 8 - 3

Thus 5 jars of jam and 3 packages of bread mix are in gift basket

Answer: area for circle is  πr² so πr² =28.26 and we can sub 3.14 as pi

3.14*r²=28.26 we can divide by 3.14 to get r² on it's own

r²=28.26/3.14

then we root both sides to get r on it's own

28.26/3.14=9 √9=3

Answer:

  (x -a)^2 + y^2 = 2a^2

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is ...

  (x -h)^2 +(y -k)^2 = r^2

Here r^2 is the square of the distance between the center and the point on the circle. That can be found using the distance formula:

  d^2 = r^2 = (x2-x1)^2 +(y2 -y1)^2 = (0-a)^2 +(-a-0)^2 = 2a^2

Filling in the above formula with (h, k) = (a, 0) and r^2 = 2a^2, we find the equation to be ...

  (x -a)^2 +y^2 = 2a^2

Answer:

Part A:  For no solution ⇒ 3x + 9 + 4x + x = 8x + 0

Part B:  For one solution ⇒ 3x + 9 + 4x + x = 0 * x + 1

Part C:  For infinitely many solutions ⇒ 3x + 9 + 4x + x = 8x + 9

====================================

Step-by-step explanation:

Part A:

3x + 9 + 4x + x = 8x

8x + 9 = 8x ⇒ Subtract 6x from both sides,

9 = 0 which is absurd and hence the equation has no solution.

=====================================

Part B:

3x + 9 + 4x + x = 0 * x + 1

∴ 3x + 9 + 4x + x = 1

8x + 9 = 1 ⇒ Subtract 9 from both sides.

8x = 1 - 9 = -8 ⇒ Divide both sides by 8.

x = -1      ⇒ this is the only solution.

======================================

Part C:

3x + 9 + 4x + x = 8x + 9

8x + 9 = 8x + 9

Subtract 8x from both sides,

9 = 9, both sides are balanced which means, the equation has infinitely many solutions.

The range is [tex]\{-9,-8,-7,-6,-5\}[/tex]

The graph in the attached figure

Step-by-step explanation:

we have

[tex]y=x-7[/tex]

The domain is the interval [tex]\{-2,-1,0,1,2\}[/tex] ----> given problem

Remember that

The domain of a function is the set of all possible values of x

The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.

To find out the range of the function , find the value of y for each value of x

so

For x=-2 ----> y=-2-7=-9

For x=-1 ----> y=-1-7=-8

For x=0 ----> y=0-7=-7

For x=1 ----> y=1-7=-6

For x=2 ----> y=2-7=-5

therefore

The range is [tex]\{-9,-8,-7,-6,-5\}[/tex]

speed of a boat when it goes downstream is 336/12 = 28 mi/h

speed of a boat when it goes upstream is 336/14 = 24 mi/h

v + x = 28

v - x = 24

Solve the system for v and x and get v = 26 mi/h, x = 2 mi/h
