Answer: \frac{10p}{2q}=\frac{5p}{q}  (TRUE)

Step-by-step explanation:

For this exercise it is important to remember that, by definition, fractions have the following form:

\frac{a}{b}

Where "a" is the numerator and "b" is the denominator.

The numerator and the denominator are Integers, but the denominator cannot be zero (b\neq 0)

In this case you have the following equation provided in the exercise:

\frac{10p}{2q}=\frac{5p}{q}

To find out if the left side of the equation is equal to the right side, it is necessary to simplify the fraction on the left.

Notice that the numerator and the denominator of the fraction on the left  can be both divided by 2. Then, you can simplify it.

So, you get;

\frac{5p}{q}=\frac{5p}{q}\ (TRUE)

Car A travels 120 miles in the same time that car B travels 150 miles. If car B averages 10 mph faster than car A, what is the s
amid [387]

Answer:

Speed of car A = 40 mph

Speed of car B =  50 mph

Step-by-step explanation:

Given:

Distance travelled by car A  = 120 miles

Distance travelled by car B  =  120 miles

To Find:

speed of each car = ?

Solution:

Let the speed of car A be x

then  speed of car B is (x +10)

The Time taken for each car is same

Time taken for car A =  Time taken for car B

We know that time  = \frac{distance}{speed}

Time taken for car A

=> \frac{120}{x}---------------------------(1)

Similarly

Time taken for car B

=> \frac{150}{x+10}-----------------------(2)

Equating (1) and (2), we get

\frac{120}{x} =  \frac{150}{x+10}

120 \times (x+10) = 150 \times x

120x + 1200 = 150x

1200 = 150x-120 x

1200 = 30x

x= \frac{1200}{30}

x= 40

Speed of car A = 40mph

Speed of car B = (x+10) = (x+40) = 50mph

March 21, the 80th day of the year, is the spring equinox. find the number of hours of daylight in fairbanks on this day
pentagon [3]
According to a daylight calculator for Fairbanks, AK, sun rises at 07:40 and sun sets at 20:12, giving 12 hours and 32 minutes of daylight.

Note that it is not a mistake that daylight is not exactly 12 hours on that day due to refraction of the sun's rays at sunrise and sunset.

At Fairbanks, near equality to 12 hours occurs on March 16 with sunrise at 07:58 and sunset at 19:57.

How do properties of integer exponents help you write equivalent expressions
olga55 [171]

When writing equivalent expressions, there are often several possible orders in which to simplify them. However, they will all take you to the same result as long as you do not make a mistake when using the properties. In this example, you will distribute the outer exponent first using the Power of a Product Property.

Answer:  " m∠SRW = 95 ° " .
________________________________________________

Since m∠TRV = 95° ; 

and:  ∠TRV and ∠SRW are vertical angles; 

and:  we are given:  " m∠TRV = 95° " ; 

and:  vertical angles are congruent; 

So, m∠TRV = m∠SRW = 95°  .
