if there are 90 calories in 3/4 cuo of yogurt how man calories are in 3 cups of yogurt 30 calories 202 calories 270 calories 360
Debora [2.8K]
Hello!

To find how many calories in three cups we can use the proportion below.

\frac{calories}{cups} = \frac{90}{3/4} = \frac{c}{3}

To find our answer we can say, "How many times does 3/4 go into 3," and then multiply that number by 90 as shown below.

3÷3/4=4
90(4)=360

Just to verify, we will cross multiply and check our answer 

90(3)÷3/4
270÷3/4=360

Therefore, our answer is D) 360 calories.

I hope this helps!

The line plot shows the growth, In Inches, of Isabella's plant over 13 days. Growth of Isabella's Plant What is the total growth
mart [117]

Line plots are used to display data elements using markers

The total growth, in inches, of Isabella's plant is 4\frac{1}2 inches

<h3>How to determine the total growth</h3>

From the line plot, the total growth can be represented as:

Total = \frac 18 * 4 + \frac 28 * 2 + \frac 38 * 3 + \frac 48 * 1 + \frac 58 * 3

Evaluate the products

Total = \frac 48+ \frac 48 + \frac 98 + \frac 48 + \frac {15}8

Evaluate the sum

Total = \frac{4+4+9+4+15}8

Evaluate the numerator

Total = \frac{36}8

Evaluate the quotient

Total = 4\frac{1}2

Hence, the total growth, in inches, of Isabella's plant is 4\frac{1}2 inches

Double is double, so you can solve
.. 2 = 1*e^(.08t)
and get the correct value of t.

Taking logs,
.. ln(2) = .08t
.. ln(2)/.08 = t ≈ 8.7 . . . . years
