Suppose 15% of x equals 20% of y. What percentage of x is y ?

Answer:

d

Step-by-step explanation:

becasuse when you  multiply all that stuff since x is the is y fancy way o f saying

From the calculations, we can see that the true statement is  f(-3) = g(-2): Option D is correct.

Given the following functions

f(x) = (2x + 1)²– 3 and g(x) = 2(2x² + 3),

According to the last option.

f(-3) = (2(-3) + 1)²– 3

f(-3) = (-6+1)² - 3

f(-3) = (-5)² - 3

f(-3) = 25 - 3

f(-3) = 22

For g(-2)

g(-2) = 2(2x² + 3),

g(-2) = 2(2(-2)² +3)

g(-2) = 2(8+3)

g(-2) = 2(11)

g(-2) = 22

Hence from the calculations, we can see that the true statement is  f(-3) = g(-2)

Answer:

D. 181.7 miles

Step-by-step explanation:

If the odometer can read to the nearest 0.1 miles, then you don't want to use A because its not as precise. You don't want to use B because its rounded up to the nearest hundreds. You don't want to use C because we don't know whats in the hundredths place, if the odometer only reads to the nearest 0.1 miles then it could be 181.3, or 181.9, we don't know that. Your answer is D.

Answer:

Step-by-step explanation:

Given the price of 10packs as $41.50, we can express it as;

10 packs = $41.50

To get the equivalent price of 1 pack, we will say;

1 pack = $x

Solving both equalities for x;

10 packs = $41.50

1 pack = $x

cross multiply

10 * x =  1 * 41.50

10x = 41.50

Divide both sides by 10

10x/10 = 41.50/10

x = 4.150

Hence the price for each pack is $4.150

Okay so!

Step-by-step explanation:

for a cut that's .87 and for a color that is .24 so you multiply them together to get the probability for the color which is

.35 or C on edge

The probability that a randomly selected customer gets their hair cut and colored is .

Probability is the chance of happening an incident or event. A probability is calculated by the ratio of the possible outcomes to total number of outcomes.

Given, the probability of he customer get a hair cut is = P(A) = 87% = 0.87.

The probability of he customer get their hair colored is = P(B) = 40% = 0.4.

Therefore, the probability of a randomly selected customer get hair cut and hair color is = P(A) × P(B) = 0.87 × 0.4 = 0.35

Therefore, 35% of the total customer get hair cut and color.

Answer:

1. x-5=3x-45

2. x=20

3.Perimeter is 45 units since each side is 15 units.

Step-by-step explanation:

x-5=3x-45

-5=2x-45

40=2x

x=20

So AB is 15 and AC and BC is also 15 since it is equilateral. 15+15+15=45 The perimeter is 45 units.

Answer/Step-by-step explanation:

1) First, add or subtract both sides of the linear equation by the same number.

2) Secondly, multiply or divide both sides of the linear equation by the same number.

3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable.

Answer:

D =  [tex]\frac{-d}{-2}[/tex]

Step-by-step explanation:

The students in this question are trying to pay back only half of the current debt (d) with the fundraiser (D). Since debt is money that is owed it would therefore be represented as a negative but in this case the fundraiser needs to be positive since it is money gained. So since we have a negative we would need to divide by -2  in order for the total to be positive.

D =  [tex]\frac{-d}{-2}[/tex]

Finally, we are left with this equation which shows the debt that will be repaid through the fundraiser

Answer:

  y = 2x -6

Step-by-step explanation:

One form you can use for this purpose is ...

  (x2 -x1)(y -y1) = (y2 -y1)(x -x1)

Filling in the given point values, this is ...

  (0 -4)(y -2) = (-6 -2)(x -4)

  -4y +8 = -8x +32

Generally, we like the equation to have coefficients with no common factors. All of these coefficients can be divided by -4.

  y -2 = 2x -8

This can be rearranged to any form you may like--or left as is.

  y = 2x -6 . . . . . slope-intercept form

Answer:

13.35

Step-by-step explanation:

Just subtract. 15.25-1.9 gives you the difference.

Mai used 13.35 gallons of fuel.

Unitary method is a process by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.

To calculate the fuel Mai used, we can subtract the remaining fuel from the initial amount of fuel.

This can be done as follows:

Initial amount of fuel = 15.25 gallons

Remaining amount of fuel = 1.9 gallons

Fuel used = Initial amount of fuel - Remaining amount of fuel

Therefore, Fuel used = 15.25 - 1.9

Fuel used = 13.35

Therefore, We can conclude that Mai used 13.35 gallons of fuel.
