Answer 1

The correct answer is B!

Answer 2

Answer:

The answer is B) a = -7/16

Step-by-step explanation:

3/4 + 4a/7 = 6a/7 + 7/8

By transposing, we get

=> 3/4 - 7/8 = 6a/7 - 4a/7

=> (by taking LCM) 6-7/8 = 6a-4a/7

=> -1/8 = 2a/7

=> -7 = 16a (by cross multiplication)

=> a = -7/16

A middle school has an oval track with the dimensions shown. What is the distance around the track? use 3.14 for π. show your work.

I think the asnwear is 10859.94
I’m sorry if I’m wrong :{

The distance around the oval track would be 556.9 m which is the sum of the perimeter of the square and the circumference of the semi-circles.

What is the Circumference of a circle?

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

C = πd

where 'd' is the diameter of the circle

We have to determine the distance around the track

The required distance is equal to the sum of the perimeter of the square and the circumference of the semi-circles.

A middle school has an oval track with the dimensions shown.

Here the length of a side of the square = 78 m

And the diameter of the circle = 78 m

the distance around the track = perimeter of square + circumference of the circle

the distance around the track = 4 × 78 + π × 78 / 2 + π × 78 / 2

the distance around the track = 4 × 78 + π × 78

the distance around the track = (4 + π) × 78

the distance around the track = (4 + 3.14) × 78

the distance around the track = 7.14 × 78

the distance around the track = 556.9 m

Therefore, the distance around the oval track would be 556.9 m.

The Ramirez family has a circular garden with a diameter of 22 feet. They cover the garden with mulch. The cost of mulch is $1.25 per square foot. To the nearest dollar, how much will it cost to cover the garden with mulch. Show your work.

A.$380 B. $475
C. $1.520 D. 1.900

Answers

Answer:

b) $475

Step-by-step explanation:

if it has a diameter of 22 feet, that means it has a radius of 11 feet

the formula of the area of a circle is πr². so square the radius and you will get 121, multiply that by π and you get 380

Now we know the area is 380 square feet, so multiply that by $1.25 and the answer is $475

b) $475
Step-by-step explanation:
if it has a diameter of 22 feet, that means it has
a radius of 11 feet
the formula of the area of a circle is Tr?. so
square the radius and you will get 121, multiply
that by TI and you get 380
Now we know the area is 380 square feet, so
multiply that by $1.25 and the answer is $475

On the first visit to the veterinarian's office, Cora's kitten weighed 550 grams. On the second visit, the kitten had gained 350 grams. On the third visit, the kitten had gained another 300 grams.
What is the percent increase since the first visit in the kitten’s weight rounded to the nearest percent?

PLSS HELPP

Answers

Answer:

On first visit, weight =550 g

Weight gained on second visit= 350 g

Weight gained on third visit= 300 g

Present weight=550+350+300= 1200

Weight gained=1200-550=650

Percentage of weight increased

-------->650/550 × 100 = 118.18\%

So the kitten gained 118% weigh

I think the answer is 7. 5 miles

Answer:

7.5mph (1 d.p)

Step-by-step explanation:

First, I worked out what a third of an hour was to match the unit mph.

60 minutes / 3 = 20 mins

A third of an hour is 20minutes so two thirds of an hour is 40 minutes.

But as we know, one third as a decimal is 0.33(reccuring) so therefore two thirds as a decimal is 0.66, which we need to use.

Now, we need to remember the equation. Speed = distance / time

Place the facts we already know in place.

speed = 5miles / 0.66 (using a calculator.)

speed = 7.5mph (1 d.p)

Hope this helps and you have a good day!

Carl bought 19 apples of 2 different varieties to make a pie. The total cost of the apples was $5.10. Granny Smith apples cost $0.25 each and Gala apples cost $0.30 each. How many of each type of apple did Carl buy?

Answers

Answer:

Step-by-step explanation:

Split 19 into 2, since Carl bought two types of apples.

19/2 = 9.5

0.25 x 9 = 2.25

0.3 x 9 = 2.7

2.25 + 2.7 = 4.95

5.10 - 4.95 = 0.15

0.3 x 8 = 2.4

2.25 + 2.4 = 4.65

5.1 - 4.65 = 0.45
