Answer:

x=15

Step-by-step explanation:

Since, the grid only has 100 squares, and the total number of cars is 180, you have to make a proportion.

\frac{27}{180}=\frac{x}{100}

(27 of the 180 cars are minivans. x of the 100 cars are minivans.)

Now, you cross multiply. <u>180 times x</u> is 180x

<u>100 times 27</u> is 2700

Now, equal them to each other and solve for x:

180x=2700

x=15

To check your answer, plug in 15 for x:

27/180 <em>should equal to</em> 15/100...

\frac{27}{180}=.15

\frac{15}{100}=.15

...they do!

TEA [102]

Answer:

<h2>x = 745.5 ft</h2>

Step-by-step explanation:

Look at the picture.

Use sine:

sine=\dfrac{opposite}{hypotenuse}

We have a measure of the angle and length of the opposite:

\alpha=28^o,\ opposite=350\ ft

\sin28^o\approx0.4695

Substitute:

\dfrac{350}{x}=0.4695

\dfrac{350}{x}=\dfrac{4695}{10000}            <em>cross multiply</em>

4695x=3500000           <em>divide both sides by 4695</em>

x=\dfrac{3500000}{4695}\to x\approx745.5

Suppose a lab needs to make 400 liters of a 39% acid solution, but the only solutions available to the lab are 20% acid and 50%
Alekssandra [29.7K]
Mixture problem.
Ratio of 20% : 50% acids
=50-39 : 39-20
=11:19
total volume
=400L
vol. of 20% acid=400*(11/(11+19)=400*(11/30)=146.667 L
vol. of 50% acid=400*(19/(11+19)=253.333 L

Alternatively, use c=volume of 20%, d=vol of 50%
then
0.2c+0.5d=400*0.39
Since c+d=400, we have
0.2c+0.5(400-c)=400*0.39=156
solve for c:
0.3c=44
c=146.667 and d=400-c=253.333  as before.
