ValentinkaMS [17]

1 / 128 = (2/3) / x....1 cup to 128 grams = 2/3 cups to x grams
cross multiply
(1)(x) = (128)(2/3)
x = 256/3
x = 85.3

he went over...
85.3 - 32 = 53.3....he went over by 53.3 (or 53 1/3) grams

mary is making a batch of chocolate chip cookies the recipe calls for 9 cups of flour and 2 4/7 cups of sugar she isshort on flo

Harman [31]

Mary added $$24 \frac{1}{2}$ cups of sugar.

<h3>How to estimate how much sugar should Mary add?</h3>

The ratio of flour to sugar exists at 9 cups: 2 4/7 cups

Utilizing equivalent ratios, given that 7 cups of sugar was utilized,

Let cups of flour needed = x such that our equation becomes

flour/sugar $$ =\frac{9}{2\frac{4}{7} }=\frac{x}{7}$

$$ \frac{9}{2\frac{4}{7} }=\frac{x}{7}$

Convert mixed numbers into improper fractions

$$2 \frac{4}{7}= \frac{18}{7}$

simplifying the above equation, we get

$$\frac{9}{\frac{18}{7} } = \frac{x}{7}$

= $$24 \frac{1}{2}$

x = 24.5

The value of x = 24.5.

Therefore, $$24 \frac{1}{2}$ cups of sugar exist required.

Find the area of a triangle with a base of 7.5 m and a height of 4*

oksian1 [2.3K]

Answer:

15 units²

Step-by-step explanation:

Hi there!

$A=\displaystyle\frac{1}{2} bh$ where <em>b</em> is the base and <em>h</em> is the height

Plug in the base (7.5) and height (4):

$A=\displaystyle\frac{1}{2} (7.5)(4)\\\\A=\displaystyle\frac{1}{2} (30)\\\\A=15$

Therefore, the area of the triangle is 15 units².

I hope this helps!
