Answer:

4 11/20

Step-by-step explanation:

Using bidMAs Multiplication comes first before addition

2/5 * 7/6 = 14/30

7/6 * 7/2 = 49/12

Make denominators equal

14/30 * 2 = 28/60

49/12 * 5 = 245/60

Then add

28/60 + 245/60 = 273/60

Finally convert improper into mixed fraction

4 11/20

Trey had a cylindrical can with a radius of 4 inches and a height of 12 inches that was completely full of beet juice. He poured

Arisa [49]

Answer:

$8\ glasses\ of\ juice$

Step-by-step explanation:

step 1

Find the volume of the cylindrical can

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=4\ in\\ h=12\ in$

substitute the values

$V=\pi (4)^{2}(12)=192\pi\ in^{3}$

step 2

Find the volume of the cylindrical glasses

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=2\ in\\ h=8\ in$

substitute the values

$V=\pi (2)^{2}(8)=32\pi\ in^{3}$

Find the volume of 3/4 of the glass

$32\pi (\frac{3}{4})=24\pi\ in^{3}$

step 3

Divide the total volume of cylindrical can by the 3/4 volume of the glass

$192\pi\ in^{3}/24\pi\ in^{3}=8\ glasses\ of\ juice$

the calorie cafe is known for their hotdogs and burgers. the number of calories in a burger is 220 more than the number of calor

meriva

Answer:

Number of calories in burger = 620 calories

Number of calories in hotdog = 400 calories

Step-by-step explanation:

Number of calories in burger = x

Number of calories in hotdog = y

y = x - 220

x + 2y = 1,420

Substitution:

x + 2 * (x - 220) = 1,420

x + 2x - 440 = 1,420

3x = 1,420 + 440

x = 1,860 / 3

x = 620 calories

y = x - 220

= 620 - 220

= 400 calories
