On a scale drawing with a scale of 1cm=0.75m the height of a tree is 6.5 cm how tall is the actual tree?

1 answer:

7 0

X=real height of the tree
1 cm / 0.75 m=6.5 cm / x
x*1cm=0.75 m*6.5 cm
x=(0.75 m*6.5 cm) / 1 cm=4.875 m

therefore: the real height of a tree is 4.875 m,

One serving of a certain brand of yogurt contains 12 G of fat the low-fat version contains 38.75% less fat per serving how many

Mkey [24]

Answer:

One serving of law-fat yogurt contains 7.35 g of fat.

Step-by-step explanation:

One serving of

a certain brand of yogurt contains 12 g of fat
the low-fat yogurt contains 38.75% less fat

Let x g be the amount of fat in low-fat yogurt. Then

12 g of fat - 100%

x g of fat - 100% - 38.75% = 61.26%

Write a proportion

$\dfrac{12}{x}=\dfrac{100}{61.25}$

Cross multuply

$100\cdot x=12\cdot 61.25\\ \\100x=735\\ \\x=\dfrac{735}{100}=7.35$

One serving of law-fat yogurt contains 7.35 g of fat.
