Answer 1

Answer:

C

Step-by-step explanation:

Area = π[tex]r^{2}[/tex]

r means radius

radius = d/2

d = diameter

8 /2 = 4

4 is radius

[tex]4^{2}[/tex] = 16

^ ( its 4 x 4 ) ^

so then,

Area = 16π

Answer 2

Answer:

Step-by-step explanation:

[tex]A=\pi r^2,\ r=\frac{d}{2}\\ \\ A=\frac{\pi d^2}{4},\ d=8cm\\ \\ A=\frac{64\pi}{4}\\ \\ A=16\pi cm^2[/tex]

Jessica is shopping for a new car. She found a blue car that has a 12-gallon gas tank and can go 384 miles on one tank. She found a silver car that has a 14-gallon gas tank and can go 504 miles on one tank. Which car gets better gas mileage?

Answers

Answer:

Silver car

Step-by-step explanation:

It seems pretty hard but it's actually REALLY easy. gas mileage means the number of miles you can go on a particular amount of gallons. But the gallons have to be the same for both cars so that it's fair.

so let's go with 10 gallons. pretty broad number right?

so to get 12 gallons(the gallons for the blue car) to 10, We divide it by 12 then multiply it by 10. Try it yourself, (12/12)*10=???

then we do that to 384 (the miles for the blue car)

(384/12)*10=320

so 320 is the mileage for the first car. Repeat the steps for the silver car!

(14/14)*10=10

so then: (504/14)*10= 360.

So which is bigger, 320 or 360?

360 is bigger, meaning it has better gas mileage.

5 folders and 5 pens = yes

6 pens and 6 erasers = yes

1 pen and 4 notebooks = no

3 folders and 7 erasers = no

4 folders and 2 notebooks = yes

Step-by-step explanation:

Max total = $10

(5 folders x 1.29) + (5 pens x 0.70)

6.45 + 3.50 = 9.95

(6 pens x 0.70) + (6 erasers x 0.89)

4.20 + 5.34 = 9.54

(1 pen × 0.70) + (4 notebooks × 2.35)

0.70 + 9.40 = 10.10

(3 folders × 1.29) + (7 erasers × 0.89)

3.98 + 6.23 = 10.21

(4 folders × 1.29) + (2 notebooks × 2.35)

5.16 + 4.70 = 9.86

Determine this one algebraically

Answers

Answer:

x = 5

y = 5

Step-by-step explanation:

In this question you need to solve one equation in order to plug the value into the second one and solve it as well. Lets start with the top one...

2x - x = 5

1x = 5

x = 5

Now we plug that value of x into the second equation

4x - 2y = 10

4(5) - 2y = 10

20 - 2y = 10

-2y = -10

y = 5

Finally, we can see that both x and y have a value of 5.

km will will cancelled out

The time taken to travel 432 Km at an average speed of 96 Km/h is 4.5 h

What is average speed?

Average speed is defined as the total distance travelled divided by the total time taken to cover the distance.

Average speed = Total distance / total time

How to determine the timeTotal distance = 432 KmAverage speed = 96 Km/hTime =?

Average speed = Total distance / total time

96 = 432 / time

Cross multiply

96 × time = 432

Divide both side by 96
