Abby went to the store to buy ice cream for her party. Each box costs $3. She has a coupon for 20% off her total. If Abby buys 3 boxes, what will she pay after using the coupon?

Answers

Answer: 7.2$

hope it helps :)

step-by-step explanation:

Cost of each box = 3$

Cost of 3 boxes without 20% coupon = 9$

With 20% off Coupon = 9 by 100 multiplied by 20

                                     (the zero's cut with each other leaving)

                                     = 9 by 10 multiplied by 2

                                     (9 multiplied by 2 = 18)

                                     = 18 by 10

                                     (18 divided by 10 = 1.8)

                                     = the 20% of 9$ is equal to 1.8

                                        when subtracted with the total cost leaves 7.2$

usain bolt broke the world record for the mens 100 m sprint with a time of 9.58 seconds. Florence Griffith Joyner broke the world record for the womens 100 m sprint with a time of 10.49 seconds. If florence and usain were running at their world-record speed in the same race, how many metres behind usain would florence finish?

Answers

Answer:

If Florence Griffith Joyner and Usain Bolt were running at their world-record speed in the same race, Florence Griffith Joyner would finish 8.67 m behind Usain Bolt.

Step-by-step explanation:

Step 1: Determine the speed of each athlete in m/s

Speed = distance / time

Distance = 100 m

Usain Bolt's speed: 100m / 9.58 s = 10.438 m/s

Florence Griffith Joyner's speed: 100 m/ 10.49 s = 9.533 m/s

Step 2: Determine the distance covered by Florence Griffith Joyner in 9.58 s

Distance = Speed × time

Distance covered by Florence Griffith Joyner = 100 m/ 10.49 s × 9.58 s = 91.32 m

Step 3: Determine the difference in the distance covered by Usain Bolt and Florence Griffith Joyner after 9.58 s

After 9.58 s, Usain Bolt have covered a distance of 100 m

After 9.58 s, Florence Griffith Joyner have covered a distance of 91.33 m

Difference between the distances = (100 - 91.33) m = 8.67 m

Therefore, if Florence Griffith Joyner and Usain Bolt were running at their world-record speed in the same race, Florence Griffith Joyner would finish 8.67 m behind Usain Bolt

i am a multiple of 7 and divisible by 4 if i am less than 30 what number am i?

Answers

Answer: 28

Step-by-step explanation:

The multiples of 7 that's less than 30 include: 7, 14 , 21 and 28.

From the numbers above,

7 isn't divisible by 4 as it gives a remainder.

14 isn't divisible by 4 as it gives a remainder.

21 isn't divisible by 4 as it gives a remainder.

28 is divisible by 4 without a remainder

Therefore, the correct answer should be 28

represented by the equation c = 0.19m + 9.00

Plan B to be less expensive than Plan A

Answers

Answer:

225 and greater

Step-by-step explanation:

900/4 or 900 cents/ 4 cents equals 225 on calculator

We use 225 minutes for Plan B to be less expensive than plan A.

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

For plan A,

We can pay 23 cents per minute.

This can be represented by the equation,

C= 0.23m

For plan B,

We can pay 19 cents per minute plus a flat fee of $9.00.

This can be represented by the equation,

C = 0.19m + 9.00

Now, To find the minutes for plan B is less expensive than plan B

We can write an inequality that represent,

Plan A < Plan B

0.23m < 0.19m + 9

0.23m - 0.19m < 9

0.04m < 9

Divide 0.04 both side,

m < 225

Thus, We use 225 minutes for Plan B to be less expensive than plan A.

Find the surface area of the
prism.

Answers

Answer:

D. 464 ft²

Step-by-step explanation:

Area of trapezoidal prism = h(b + d) + l(a + b + c + d)

Where,

h = 4 ft

a = 5 ft

b = 6 ft

c = 5 ft

d = 12 ft

l = 14 ft

Plug in the values into the formula

Area of trapezoidal prism = 4(6 + 12) + 14(5 + 6 + 5 + 12)

= 4(18) + 14(28)

= 72 + 392

= 464 ft²
