Find the cost of a car if it costs $25000 plus 18% VAT.
larisa [96]

Answer:

The car costs $29,500 after the value tax.  

Step-by-step explanation:

First, put the percentage into decimal form.  Since we are adding on the tax, add an additional 1 into the decimal.  

This is what we will use to multiply with: 1.18.

We know the cost of the car, $25,000 and it's VAT, 18%.

To determine how much it will cost after the added value tax, we multiply $25,000 with 1.18 because it is an additional cost to that car specifically.  

25,000 x 1.18 = 29,500

The car costs $29,500 after the value tax.

How do I find the measure of the interior angle?
nataly862011 [7]

Answer:

see the explanation

Step-by-step explanation:

we know that

The sum of the interior angles in any polygon is given by the formula

S=(n-2)180^o

where

n is the number of sides of the polygon

step 1

Find the sum of the interior angles in the given polygon

we have

n=5\ sides

substitute

S=(5-2)180^o=540^o

step 2

Find the value of x

we know that

-3x+125+(45-x)+(-x+90)+80=540

solve for x

-5x+340=540

-5x=200\\x=-40

step 3

Find the measure of each interior angle

substitute the value of x

Angle A

-3(-40)=120^o

Angle B

80^o

Angle C

-(-40)+90=130^o

Angle D

45-(-40)=85^o

Angle E

125^o

Q7.
VLD [36.1K]

Answer:

10

Step-by-step explanation:

Let c = sum of ages of all children.

mean age of all children = c/15 = 7

c = 15 * 7 = 105

The sum of the ages of all children is 105.

Let b = sum of ages of the 9 boys.

mean age of boys = b/9 = 5

b = 9 * 5 = 45

The sum of the ages of the boys is 45.

The sum of the ages of the girls is c - b.

c - b = 105 - 45 = 60

The number of girls is 15 - 9 = 6

mean age of girls = (sum of ages of the girls)/(number of girls) =

= 60/6 = 10

Slope Formula:

\frac{y_2-y_1}{x_2-x_1}

We can plug in the numbers 7 and -2 for the y and -4 and 3 for x

\frac{7-(-2)}{-4-3} =\frac{9}{-7}
