Answer:

Cameron will do 79 jumping jacks on Sunday

Step-by-step explanation:

So on Wednesday, he did 4 jumping jacks. On Thursday, he did 5 more jumping jacks than he did on Wednesday (9 total ). On Friday, the difference between Wednesday and Thursday doubled, and it has a difference of 10 new jumping jacks(19 total). On Saturday, the difference between Thursday and Friday doubled from 10 to 20, (39 total). So if the difference keeps up, which it should, The difference between Saturday and Sunday should double from the diffeerence from Friday to Saturday (a difference of 20). So if the difference is doubled, it will be a difference of 40. so 39+40=79.

Answer:

segment R prime S prime = three segment RS

Step-by-step explanation:

I took the test,

The true statement is segment R prime S prime = three segment RS

Dilation is a transformation, which is used to resize the object.

The complete question is

If ΔOPQ is dilated from point Q by a scale factor of 3, which of the following equations is true about segment R prime S prime?

Triangle OPQ is shown with point R lying on side OP and point S lying on side OQ Line RS is perpendicular to side OQ.

segment R prime S prime = one half segment RS

segment R prime S prime = two segment RS

segment R prime S prime = segment RS

segment R prime S prime = three segment RS

The scale factor of dilation of ΔOPQ, S.F. = 3

S'Q' = 3 * SQ

also, R'Q' = 3* RQ

By Pythagoras theorem, we have

R'Q'² = R'S'² +S'Q'²

R'S'² = R'Q'² - S'Q'²

R'S'² = (3RQ)² - (3SQ)²

R'S'² = 9(RQ² - SQ²)

R'S' = 3 RS

Answer:

v = 20 Sundaes

Step-by-step explanation:

Total number of sundaes = 25

Let the number of mint = m = 1/5 of total

= 1/5 of 25 = 1/5 × 25 = 5

∴ m = 5

Remainder = 25 - 5 = 20 Sundaes

let the number of chocolate = c = 1/2 of the remainder

1/2 of remainder = 1/2 of 20 = 20 ÷ 2 = 10 sundaes

∴ c = 10

let the number of vanilla = v

Therefore, finding v

25 = m + c + v

25 = 5 + 10 + v

25 = 15 + v

25 - 15 = v

v = 20 Sundaes

Answer:

Step-by-step explanation:

Amaya went to the pet store. She bought x fish for $3.50 each. She bought fish food for $7.00, and a fish bowl for $12.75. Determine how much Amaya spent at the pet store if she bought 4 fish.

Step 1

We calculate the total amount spent on 1 fish

= Cost of fish + Cost of food + Cost if bowl

= $3.50 + $7.00 + $12.75

= $23.25

Step 2

The total amount spent on 4 fishes is calculated as

= $23.25 × 4 fishes

= $93

Answer:   [tex]\huge\boxed{\ m=7 }[/tex]

Step-by-step explanation: We can break this problem down to understand it.  Let the number be m. Three times the number 'm ' is 3.m or 3m. 3 ( m ) - 6 = 15. 3m -6 = 15 add 6 to both sides; 3m -6 + 6 = 15 + 6 3m = 21 dividing both the sides by 3 ,and  we get; 3m /3 = 21 / 3 m=7 .

Answer:

There will be 10 cats in 5 years

Step-by-step explanation:

Since x means the number of years, x = 5

According to PEMDAS, we take care of the exponents first

So the exponent is x, so the exponent is actually 5

So we apply that to 0.28

0.28^5 = 0.002

0.002 x 5719 = 9.84

But... that would be impossible and just plain creepy if there were 9.84 cats lol

So I rounded it to 10 cats

Answer:

[tex]\Large\boxed{\sf 10 \ cats}[/tex]

The Answer Is 72+24x

Step-by-step explanation:

1/3 with both sides multiplied by two in order to have same denominator of both fractions, which is 6.

(1/3) x (2/2) = 2/6

Replacing 1/3 with 2/6,

the [ 1/3 - 5/6] becomes [2/6 - 5/6]

2/6 - 5/6 = -3/6

Simplify -3/6 by dividing both sides with 2,

-3/6 becomes -1/2

Answer:

8 boxes of tissues

5 bags of cough drops

Step-by-step explanation:

You need to write a system of equations.

x = number of tissue boxes

y = number of cough drop bags

x (number of tissue boxes) + y (number of cough drop bags) = 13 (total number of tissues and cough drops combined.

So, your first equation is

x + y = 13

Then, you need to write the second equation.

(1.69 [cost of 1 tissue box] * [number of tissue boxes]) + (1.19 [cost of one bag of cough drops] * [number of cough drop bags] = 19.47 [total cost of tissues and cough drops]

That's a lot to read, so here's the equation simplified!

1.69x + 1.19y = 19.47

Now, you have two equations:

x + y = 13

1.69x + 1.19y = 19.47

I would solve with the substitution method.

the first equation can be changed to x = 13 - y by subtracting y from both sides.

Then, your two equations are:

x = 13 - y

1.69x + 1.19y = 19.47

Now, you can plug in that value of x into the second equation!

1.69(13 - y) + 1.19y = 19.47

21.97 - 1.69y + 1.19y = 19.47

subtract 21.97 from both sides

-1.69y + 1.19y = -2.5

Add the y values

-0.5y = -2.5

divide both sides by -0.5

so, y equals 5 bags of cough drops

now that you know what y equals, plug it back into your original equation to find x!

x + y = 13

plug in y

x + 5 = 13

x = 8

so, x = 8 boxes of tissues

Answer:

∠ GJK = 22°

Step-by-step explanation:

∠ HJI = ∠ JHG ( alternate angles ), then

7x - 16 = 5x + 8 ( subtract 5x from both sides )

2x - 16 = 8 ( add 16 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12 , so

∠ KJI = 7x - 16 = 7(12) - 16 = 84 - 16 = 68°

Then

∠ GJI = 90° ( vertex of a rectangle )

∠ GJK = 90° - 68° = 22°

Answer:

Number of apples = 6

Number of oranges = 5

Step-by-step explanation:

At a store, apples cost $0.80 each and oranges cost $0.95 each. Harry buys some apples and oranges and spends $9.55. He buys a total of 11 pieces of fruit.

Let

Number of apples = x

Number of oranges = y

x + y = 11 (1)

0.80x + 0.95y = 9.55 (2)

From (1)

x = 11 - y

Substitute into (2)

0.80x + 0.95y = 9.55 (2)

0.80(11 - y) + 0.95y = 9.55

8.8 - 0.80y + 0.95y = 9.55

- 0.80y + 0.95y = 9.55 - 8.8

0.15y = 0.75

y = 0.75/0.15

y = 5

Substitute y = 5 into (1)

x + y = 11 (1)

x + 5 = 11

x = 11 - 5

x = 6

Number of apples = 6

Number of oranges = 5

Answer:

y=3.5x

Step-by-step explanation:

Since when x is 0 when y is 0, there is no y-intercept. The ratio with the other values gives the equation y=3.5x, because y is 3.5 times larger than x.
