A pail hold 6 3/4 gallon of water. how much is this in cups

Ber [7]

There are 16 cups in 1 gallon so you would have to turn the denominator in the fraction into a 16 meaning you would multiply by 4 (because 4 goes into 16, 4 times). Your new fraction is 12/16. now you do 6 gallons*16 cups and you get 96 cups. Then you add the fraction onto 96 and you would be adding 12. Your final answer is 108 cups in 6 3/4 gallons

A picture frame (see figure) has a total perimeter of 3 feet. The width of the frame is 0.64 times its length. Find the dimensio

Naya [18.7K]

Answer:

$\approx 0.59\text{ ft by }0.91\text{ ft}$

Step-by-step explanation:

Let $\ell$ represent the length of the rectangle. The width can be represented as $0.64\ell$ .

The perimeter of a rectangle with lengths $l$ and $w$ is given by $p=2l+2w$ .

Thus, we have:

$2\ell+2(0.64\ell)=3,\\2\ell +1.28\ell=3,\\3.28\ell=3,\\\ell=0.91463414634\approx 0.91$

The width is then $0.64(0.91463414634)=0.58536585365\approx 0.59$ .

Find the surface area of a cylinder with a base radius of 2 cm and a height of 8 cm

gtnhenbr [62]

Answer:

82.6cm2

Step-by-step explanation:

$\pi {r}^{2} + \pi {r}^{2} + 2 \pi \: r h$

$\pi = \frac{22}{7}$

radius =2cm

height=8cm

$( \frac{22}{7} \times 2 \times 2 )+ ( \frac{22}{7} \times 2 \times 2) + (2 \times \frac{22}{7} \times 2 \times 8)$

Multiplying the numerators and The whole numbers, we have

$\frac{88}{7} + \frac{88}{7} + \frac{402}{7}$

Since the denominators of the fractions are the same, we add the numerators.

$\frac{88 + 88 + 402}{7} = \frac{578}{7} \\ which \: becomes \\$

$82.57{cm}^{2} = 82.6 {cm}^{2}$
