which equation is perpendicular to y= -2x + 5 ?

A) y= -2x -5
B) y= 2x -3
C) y= 1/2x -2
D) y=-1/2x+1

Answers

Ok so in order for the equation to be perpendicular, the slope have to be opposite of each other.

The original equation had -2 as the slope. The opposite of -2 is 1/2.

When the number is negative, the opposite of it is positive.
And in order for them to be completely opposite, you have to flip the number. So 2 turned into 1/2, since the denominator of 2 is 1.

And so since the opposite slope is 1/2, C is the correct answer.

(b) What per cent is1/2
dozen of one score?

Answers

Answer:

1/2 dozen of one score is 30%.

Step-by-step explanation:

As we know that 1 dozen = 12 units.

1/2 dozen = 1/2 times 12=6 units

1 score = 20 units.

By using this conversion, we get

6/2 times 100=30%

So 1/2 dozen of one score is 30%

At a car dealership, 72 trucks were sold in one month. If 60% of
the total vehicles sold were trucks, how many total vehicles were
sold that month?
A 12
B 132
C 120
D 160

Answers

Answer:

The total number of vehicles is: x = 120

Hence, option C is correct.

Step-by-step explanation:

Total trucks that were sold in one month = 72 trucks

Let 'x' be the total number of vehicles.

Given that 60% of the total vehicles sold were trucks.

Thus,

60% of x = 72

60/100 × x = 72

x = [72 × 100] / [60]

x = 120

Therefore, the total number of vehicles is: x = 120

Hence, option C is correct.

Answer:

C 120

Answer:

[tex]-\frac{4}{3}[/tex]

Step-by-step explanation:

[tex]-3 \frac{3}{5}[/tex] ÷ [tex]2 \frac{7}{10}[/tex]

Convert both mixed numbers to an improper fraction. This can be done by multiplying the denominator by the "number" part of the mixed number, then adding the result to the numerator.

[tex]- \frac{18}{5}[/tex] ÷ [tex]\frac{27}{10}[/tex]

Now divide the fractions, to divide the fractions, one will find the reciprocal of the recond fractions, and then multiply it by the first fractions. Remember, the reciprocal of a fraction is when one switched the numerator and denominator of a fraction.

[tex]-\frac{18}{5} * \frac{10}{27}[/tex]

[tex]= -\frac{180}{135}[/tex]

Simplify;

= [tex]-\frac{4}{3}[/tex]

What is the interest earned on $3,000 at a rate of 0.04 for 3 years? (Hint: Use the formula i = prt , where i represents the interest earned, p represents the principal, r represents the rate, and t represents the time.)

$3,360
$3,003.04
$360
$120

Answers

Answer:

$360

Step-by-step explanation:

You have to calculate the interest earned on $3,000, at the rate of 0.04 for 3 years.

P= $ 3000, R= 0.04 and t= 3 years.

3000 × 0.04 × 3= $360 (Answer)

Hope that helps

Have a good day :)

Answer:

$360.

Step-by-step explanation:

The interest earned on principal P, at the rate of r for the duration of t years is given by the equation I = Prt ........... (1)

Now, we have to calculate the interest earned on $3000, at the rate of 0.04 for 3 years.

Here, P = $3000, r = 0.04 and t = 3 years.

Hence, from equation (1), Interest earned, I = 3000 × 0.04 × 3 = $360 (Answer)
