Answer:

The m<LMN and m< NMP are 125 because when two lines are cut by a transversal, corresponding angles are congruent.

Step-by-step explanation:

So both the m<LMN and m<NMP are congruent so you just need to set 5x equal to 3x+50.

3 1/3 feet are cut off a board that is 12 1/4 feet long.How long is the remaining

laiz [17]

Answer:

$8\frac{11}{12}$

Step-by-step explanation:

In order to answer this question you will have to subtract 3 1/3 from 12 1/4 by turning the mixed fractions into improper fractions, finding the common denominator, (CD) then subtracting the numerators.

$12 \frac{1}{4} - 3\frac{1}{3}$

Turn the mixed fractions into improper fractions:

$12\frac{1}{4} = \frac{49}{4}$

$3\frac{1}{3} = \frac{10}{3}$

$\frac{49}{4} -\frac{10}{3}$

Find the common denominator:

$4\times3=12$

$3\times4=12$

$CD=12$

$49 \times 3 =147$

$=\frac{147}{12}$

$10\times4=40$

$=\frac{40}{4}$

Now subtract the numerators:

$147-40=107$

$=\frac{107}{12}$

Turn the improper fraction into a mixed fraction:

$\frac{107}{12} =8\frac{11}{12}$

$=8\frac{11}{12}$

Hope this helps.

If two numbers are in the ratio 5 : 7 and if

abruzzese [7]

Answer:

25 and 35

Step-by-step explanation:

Let the numbers be 5x and 7x

(5x+5)/(7x+5)=3/4

4(5x+5)=3(7x+5)

20x+20=21x +15

20-15=21x-20x

5=x

So,the numbers will be

5x=5*5 =25

7x=7*5=35

A traffic engineer records a sample of the types of vehicles that cross a bridge. She counts 112 passenger cars, 18 light trucks

Bond [772]

Answer:

<em>The approximate probability that a random vehicle is a passenger car is 74.67%</em>

Step-by-step explanation:

<u>Probability</u>

The traffic engineer records 112 passenger cars, 18 light trucks, and 20 heavy trucks. The total of vehicles recorded is n=112+18+20 = 150.

We are required to find the probability that a randomly selected vehicle crossing the bridge is a passenger car. There are 112 passenger cars, thus the probability is:

$\displaystyle p=\frac{112}{150}$

p = 0.7467

p = 74.67%

The approximate probability that a random vehicle is a passenger car is 74.67%
