Your sister’s soccer team drinks 15 liters of water during their tournament. Water coolers are sold in gallon sizes. What is the smallest gallon water cooler they will need to buy? (1 gallon 3.8 liters)

Answers

Answer: 4 gallons

Step-by-step explanation:

I am pretty sure it is 4 gallons because if you multiply 3.8(2)=7.6 and then 3.8(3)=11.4 and finally 3.8(4)=15.2

So that is why I think that the smallest gallon water cooler they will need too by is a 4-gallon cooler.

Answers

Answer:

The ratio 15:73 represents the ratio of 7th-grade football players to total players.

Step-by-step explanation:

If you add all the players together, you get 73. The number of 7th-grade football players is 15.

This is really simple! If you add the students all together you get 73! While 15 is the amount of 7 graders playing football. So 15:73

A gardener spread 2/3 of a bag of mulch evenly over his 6 equal-sized vegetable beds. How much mulch did he put on each vegetable bed?

Write your answer as a fraction or as a whole or mixed number.

Answers

Answer: 1/9

Step-by-step explanation: We can start the problem by using the concept of unit rate.

We know that the gardener spread 2/3 of a bag of mulch over his 6 vegetable beds. To find the amount of mulch per bed, we can divide the total amount of mulch by the number of beds.

So, the unit rate of mulch per bed is (2/3) / 6 = 1/9 of a bag of mulch.

So, the gardener put 1/9 of a bag of mulch on each vegetable bed.

Answer: 1/9

Step-by-step explanation:

If it was one bag, it would have been 1÷6 and the answer would have been 1/6 for each vegetable bed.

So if we do the same with 2/3, this is (2/3)/6. Let’s try this:

=[tex]\frac{2}{3}[/tex]÷[tex]\frac{6}{1}[/tex]
=[tex]\frac{2}{3}[/tex]×[tex]\frac{1}{6}[/tex]

=[tex]\frac{2}{19}[/tex]

=[tex]\frac{1}{9}[/tex]

Therefore, the gardener put 1/9th of the bag of mulch on each vegetable bed.

I think i can help! First, the rental fee is basically what you have to pay to get access to the item. It means that no matter how many hours you rent the item for, THE RENTAL FEE ALWAYS STAYS THE SAME. Next, The cost per hour is what you have to pay for every item you use the item. To figure out the cost per hour, all you need to do is multiply the cost per hour by the number of hours you are using the item. Lastly, the total cost if you are only using the item for one hour is the sum of the cost per hour and the rental fee. If you are using an item for more than an hour, like i said before, the rental fee always stays the same and you need to multiply the cost per hour by the number of hours you used the item. that’s all i can say my brains hurts now lol

Third Sheet: B) 4 units

Step-by-step explanation:

First Sheet:

Shape AKGP is the same as VWQX, meaning that the answers will be the same. Angle X is equal to angle P, meaning that the answer is 95°

Second Sheet:

Triangle SRT is equal to PQB. This means that angle Q is equal to angle R which means our answer is 33°

Third Sheet:

Since shape MQRN is equal to PKSD, we basically know the answer. The answer is 4 units because PK is equal to MQ.

The exact circumference of a circle is 25π millimeters. What is the approximate area of the circle? Use 3.14 for π. Round to the nearest hundredth if necessary.

Answers

Answer: A = 490.63 mm^2

Step-by-step explanation: Hello! To find the area of a circle, you have to find the radius of the circle from the circumference given. The formula is Circumference/2(3.14) = Radius. To find the circumference, multiply 25 x pi, or 25 x 3.14. 25 x 3.14 is 78.5. Put 78.5 in the equation for the circumference. 78.5/2(3.14) = Radius

Simplify:
78.5/6.28 = 12.5

The radius is approximately 12.5.

The formula for the area of a circle is 3.14 x r^2 = A

Put 12.5 in for r or radius

3.14 x 12.5^2 = A, 12.5^2 = 156.25

3.14 x 156.25 = A

3.14 x 156.25 = 490.625

Rounded to the nearest hundredth is A = 490.63

Answer: hope this helps ♡

The approximate area of the circle is 49.736 mm²

Step-by-step explanation:

Area of circle = π × r²

To find the radius:

25 ÷ 3.14 = 7.96178343949 (← diameter d = 2r)

7.96178343949 ÷ 2 = 3.98089171974 (radius)

π × r² =

3.14 × 3.98089171974² =

3.14 × 15.8474988843 =

49.7611464967 ≈ 49.736
