Answer:

$21.60

Step-by-step explanation:

20% can be written as 0.2

0.2 · $18 = 3.6

Add 3.6 to $18

$18.00 + 3.60 = $21.60

So the answer is $21.60

Step-by-step explanation:

just multiply 5 by 10 because 1 inch is 10 feet

Based on the corresponding angles theorem, a = 30°.

Two angles that correspond to each other are congruent based on the corresponding angles theorem.

Thus:

5x + x = 180° (linear pair)

6x = 180

x = 180/6

x = 30

Therefore:

x = a (corresponding angles)

a = 30°

Therefore, based on the corresponding angles theorem, a = 30°.

Answer:

The car will be worth £2516.22 in 5 years

Step-by-step explanation:

The rule of depreciating is  

[tex]A=P(1-r)^{t}[/tex], where

∵ Dan buys a car for £2700

∴ P = 2700

∵ It depreciates at a rate of 1.4% per year

∴ r = 1.4% = 1.4/100 = 0.014

∵ We need to find how much it will be worth in 5 years

∴ t = 5

→ Substitute all of these values in the rule above to find A

∵ [tex]A=2700(1-0.014)^{5}[/tex]

→ Use your calculator to find the answer

∴ A = 2516.22

∴ The car will be worth £2516.22 in 5 years

Answer:

C. $0.22 per box

Step-by-step explanation:

if it's two juice boxes and they cost $0.44 together. You divide by two, since there are two boxes. with that you get your answer, 44÷2=22. making the answer $0.22

The pairs of legging purchased is 3

Let the number of leggings be x.

The cost per legging is given as:

$12

So, the total amount is:

Total = 12x

The flat rate is given as:

Flat rate = 5

So, we have:

Total = 12x + 5

Your total is $41

So, we have:

12x + 5 = 41

Subtract 5 from both sides

12x = 36

Divide through by 12

x = 3

Hence, the pairs of legging purchased is 3

Ok so the general form of a circle is given by;

(x-a)²+(y-b)²=r²

where a and b are the coordinates of the center

and r is the radius of the circle

For this case we know that the center is (5,-7)

So the general equation of the circle would be;

[tex](x - 5) {}^{2} + (y - ( - 7)) {}^{2} = r {}^{2} [/tex]

[tex](x - 5 {}^{2} + (y + 7) {}^{2} = r {}^{2} [/tex]

Since we know that (-3,-1) is a point on that circle, we can say that it satisfies the equation of the circle;

[tex]( - 3 - 5) {}^{2} + ( - 1 + 7) {}^{2} = r {}^{2} [/tex]

[tex]r {}^{2} = ( - 8) {}^{2} + ( 6) {}^{2} [/tex]

[tex]r {}^{2} = 64 + 36 = 100[/tex]

So now,

[tex](x - 5) {}^{2} + ( {y + 7)}^{2} = 100[/tex]

Answer:

A = 12.554 square inches

Step-by-step explanation:

Let's start with the formulas:  

Circumference = [tex]2\pi r[/tex]; Area = [tex]\pi r^{2}[/tex]

We can use the circumference to find the radius, r, which we need for the area

12.56 = [tex]2\pi r[/tex]

Isolating r gives us [tex]\frac{12.56}{2\pi } = r[/tex]

A = [tex]\pi (\frac{12.56}{2\pi })^{2}[/tex]

Solving gives us 12.554, which you can further round if necessary.

Answer:

D

Step-by-step explanation:

using the sine ratio in the right triangle

sin20° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{11.9}{c}[/tex] ( multiply both sides by c )

c × sin20° = 11.9 ( divide both sides by sin20° )

c = [tex]\frac{11.9}{sin20}[/tex] ≈ 34.8 ( to the nearest tenth )

Answer:$63.55

Step-by-step explanation: You multiply 59.95 by 1.06

The figure contains a triangle and a semicircle

The area of the figure is 49.12 square feet

The dimension of the triangle is:

Base = 8 ft

Height = 6ft

So, the area is:

Area = 0.5 * Base * Height

This gives

Area = 0.5 * 8ft * 6ft

Evaluate

Area = 24 square feet

The radius of the semicircle is:

r = 4 ft.

So, the area is:

[tex]Area = 0.5\pi r^2[/tex]

This gives:

Area = 0.5*3.14 * 4^2

Area = 25.12 square feet

Add the calculated  areas.

Total = 24 square feet + 25.12 square feet

Total = 49.12 square feet

Hence, the area of the figure is 49.12 square feet

Answer:

The statements are not given, so i will answer it in the most general way possible:

First, let's recall two things:

Horizontal translation.

For a number A positive, we can move the graph of f(x) by A units to the right by the transformation g(x) = f(x - A)

Reflection over x

For a point (x, y), a reflection over the x-axis transforms this point into (x, - y).

Now let's analyze the problem:

A generic circle, of radius R and centered in the point (a, b) can be written as:

(x - a)^2 + (y - b)^2 = R^2.

Now let's translate this 4 units to the right:

(x - 4 - a)^2 + (y - b)^2 = R^2.

or in standard circle notation:

(x - (4 + a))^2 + (y - b)^2 = R^2.

Now the circle is centered in the point (a + 4, b).

Now let's do a reflection over the x-axis.

This means that the sign of y changes, so now we have:

(x - (4 + a))^2 + (-y - b)^2 = R^2.

But because the term with y is squared, this is the same than:

(x - (4 + a))^2 + (y + b)^2 = R^2.

Or, in standard circle notation:

(x - (4 + a))^2 + (y - (-b))^2 = R^2.

Then the circle is now centered in point (a + 4, -b).

So now you know where the circle is located, and also you can see that the radius of the circle never changed.
