Answer:

∠x = 72°

Step-by-step explanation:

since two sides are equal, their opposite angles are equal.

Then the upper angle is also equal to 54°.

Haley has 3 3/8 cups of sugar to make pies. If each pie uses 2 1/4 cups of sugar, how many pies can she make?

tester [92]

Answer:

With 3 3/8 cups of sugar Haley can make one and a half pie.

Step-by-step explanation:

The amount of sugar required to make each pie = 2 1/4 cup

Now, $2 \frac{1}{4} = 2 + \frac{1}{4} = 2 + 0.25 = 2.25$

So, Haley uses 2.25 cup of sugar foe each pie.

Total cups of Sugar Haley has = 3 3/8 cups.

Now, $3 \frac{3}{8} = 3 + \frac{3}{8} = 3 + 0.375 = 3.375$

So, the total amount of sugar Haley has is 3.375 cups.

Now, $\textrm{Number of pies she can make} = \frac{\textrm{Total cups of sugar she has}}{\textrm{Cups of sugar required for each cake}}$

= $\frac{3.375}{2.25} =1.5$

or the number of pies she can make = 1.5

Hence, with 3 3/8 cups of sugar Haley can Make 1 1/2 pie.

mario62 [17]

Answer:

$\frac{15}{2}=7.5$ minutes.

Step-by-step explanation:

Let t represent time taken by cold water faucet in minutes to fill the tub.

Part of tub filled by cold water faucet in one minute would be $\frac{1}{t}$ .

We have been given that it takes the hot water faucet 15 minutes to fill the tub by itself, so art of tub filled by hot water faucet in one minute would be $\frac{1}{15}$ .

We are also told that left on together, the cold and hot water faucets of a certain bathtub take 5 minutes to fill the tub, so part of tub filled by both faucets in one minute would be $\frac{1}{5}$ .
