Answer:

First let's find how much money the 4% is.

4/100 x 180 = $7.20

Now we add that sales tax to the cost of the telescope;

180 + 7.20 = $187.20, is what she'll pay in total.

The equation of the perpendicular line will be y = 29 / 3 - (2/3)x. Then the correct option is D.

Let the equation of the line be ax + by + c = 0. Then the equation of the perpendicular line that is perpendicular to the line ax + by + c = 0 is given as bx - ay + d = 0. If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.

The equation of the line is given below.

3x - 2y = 10

The equation of the line that is perpendicular line is given as,

2x + 3y + d = 0

The equation is passing through (7, 5). Then we have

2(7) + 3(5) + d = 0

14 + 15 + d = 0

29 + d = 0

d = - 29

Then the equation of the line is given as,

2x + 3y - 29 = 0

2x + 3y = 29

3y = 29 - 2x

y = 29 / 3 - (2/3)x

The equation of the perpendicular line will be y = 29 / 3 - (2/3)x. Then the correct option is D.

The surface area of the right triangular prism shown is 1288 m²

Area is the amount of space occupied by a two dimensional shape or object.

The prism has a triangular base with 24 m and height of 7m..

The surface area of the prism = 2(0.5 * 24 * 7) + (25 * 20) + (20 * 7) + (24 * 20) = 1288 m²

Answer:

x=4√5

Step-by-step explanation:

An equation is formed of two equal expressions. The value of x in the given equation is ±4√5.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The given equation can be solved for x as shown below,

x² = 80

x² = 2×2×2×2×5

x = √(2×2×2×2×5)

x = ± 4√5

Hence, the value of x in the given equation is ±4√5.

Answer:

x = 125°

Step-by-step explanation:

There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.

Total of angles

= (n - 2)•180°

Put in 7, because there are 7 angles.

= (7 - 2)•180°

= 5•180°

= 900°

So the total of the angles should be 900°. We know all of the angles except one.

900° = 123°+129°+128°+128°+132°+135°+ x

900° = 775° + x

Subtract 775.

125° = x

The missing angle is 125°.

Step-by-step explanation:

1. Write an equation to find the number of toppings, x, when you would pay for the same amount for Pizza A and B.

So, we have to make a relationship between Pizza A and Pizza B, and this is talking about the pizza and toppings so,

$10 + $1.50x = $12.50 + $1.00x

Now we solve for the x values and the starting amount of money,

0.50x = 2.50

and that gives us,

$5

The answer also solves for the bottom one, the answer you need on the top one is,

$10 + $1.50x = $12.50 + $1.00x

Answer:

3 + qr

Step-by-step explanation:

"increased by" means adding.

"product" indicates multiplication.

You can show that q and r are multiplied together in many ways:

qr

q(r)

(q)r

q×r

q•r

q*r

This is how you translate the phrase into an algebraic expression.

3 + qr

Answer:

Step-by-step explanation:

Sum = -14

Product = - 32

So, the factors = -16 , 2

When we add -16 +2 = -12 and when we multiply it is -32

w⁴ - 14w² - 32 =  w⁴ - 16w² + 2w² - 16 * 2

                      = w²(w² - 16) + 2(w² - 16)

                      = (w² - 16)(w² + 2)

                      = (w² - 4²)(w² + 2)

                      = (w + 4)(w - 4)(w² + 2)

Step-by-step explanation:

Replace w^2 with any other variable for eg: w^2=a

so that will make the equation:

a^2-14a-32

now factorize this equation and u can find the value of a

a^2-16a+2a-32

a(a-16)+2(a-16)

so factors= (a+2) (a-16)

since a was w^2 so replace them with w^2 and u got factors of the equation

you can also directly factorize the whole equation through middle term breaking

w^4-16w^2+2w^2-32

w^2(w^2-16)+2(w^2-16)

(w^2+2)(w^2-16)

you get the same answer

Answer:

4. 52.   5. 80%   6. 32%   7. 50 total players.

Step-by-step explanation:

4: 20% = .2 so you are going to multiply 65 by .2, and you get 13 then just subtract 13 from 65 and you get 52.

5: just do 4/5 and you get .8 which is 80%

6: just do 16/50 and you get .32 which is 32%

7: well if you notice that 35 is a multiple of 5 you can see that 35 is 70% of 50 and to prove that you can punch in 35/50 and you get .7 which is 70%

Answer:

7.3 years.

Step-by-step explanation:

A = P(1 + i)^n

9500 = 7500(1 + 0.033)^n     where n = number of years.

1.033^n = 9500/7500

n log 1.033 = log(9500/7500)

n =  log(9500/7500)/log 1.033

n = 7.28 = 7.3.
