Answer:

25%

Step-by-step explanation:

Divide 89.99 or 90 (since you are rounding) by 120, and you get .7499 or 75%.  You have 25% ($30) as the discount because 90 is 75% of $120.

Answer:

x-2y+2=0

Step-by-step explanation:

Answer:

1/15

Step-by-step explanation:

1/5 divided by three is the same as 1/5*1/3. 1*1=1 and 5*3=15

Answer:

C = 95 degrees.

Step-by-step explanation:

The line is being intersected by parallel lines, so that means that those angles will add up to 180. 180-85=95.

Answer:

n = - 5

Step-by-step explanation:

The expression is given as ;

-7n = 35

Divide both sides by -7

-7n/-7 = 35/-7

n= -5

The value of n is -5

Answer:

25.1mm²

Step-by-step explanation:

Total surface area of a cylinder = 2πr(r+h)

r is the radius = 1.2mm

h is the height = 2mm

Substitute

TSA = 2(3.14)(1.2)[1.2+2]

TSA = 7.536[3.2]

TSA = 24.1152

Hence the total surface area of the cylinder is 25.1mm²

Answer:

The

answer is actually ( in acellus that is )

24.1

Step-by-step explanation:

12cm2 or 24 because if u do b and h and subtract half u will 12

Answer:

2 meters

Step-by-step explanation:

Answer:

surface area is the answer

X= -1. That’s the answer for this

Answer:

Step-by-step explanation:

3(x6) + 8 = 5(x-5) - 1

we move all the terms to the left:

3(x6) + 8 -(5(x-5) -1 ) = 0

We add all the numbers together, and all the variables:

3x^6 - ( 5 ( X-5) - 1) + 8 = 0

We calculate terms in parentheses: - ( 5 ( x-5) - 1 ) , so :

5(x-5)-1

we multiply:

5x - 25 -1

we add all the numbers together, and all the variables:

5x - 26

back to the equation:

- ( 5 x - 26)

Answer:

Jessica scored 835 points,

and Tina scored 717 points.

Step-by-step explanation:

Let $j$ stand for Jessica Bradley, and let $t$ stand for Tina Harner. By turning the words of this problem into equations, we get:

j - 118 = t

and, j + t = 1552.

Now that we have a system of equations, all we have to do now is to solve it.

By substituting the value of t (first equation) into the second equation, we get:

j + (j - 118) = 1552.

Get rid of the parentheses:

j + j - 118 = 1552

Simplifing:

2j - 118 = 1552

2j = 1670

j = 835.

Now that we know how many points Jessica scored, we can easily find out how many points Tina scored. By sticking in the value of Jessica's score into the first equation.

835 - 118 = t

t = 717.

So, the answer to this problem is (j, t) = (835, 717).

Answer:

254.34 mm².

Step-by-step explanation:

For this problem, we use the formula to find the area of a circle, which is[tex]A=\pi r^2[/tex] . [tex]r[/tex] is the radius, which we can find by dividing the diameter by 2 and [tex]\pi[/tex] in this case is 3.14.

[tex]A=\pi r^2\\A=3.14*(18/2)^2\\A=3.14*9^2\\A=3.14*81\\A=254.34[/tex]

Therefore, the area of either face of the coin is 254.34 mm².

Answer:

Is this an incomplete question or?

Answer:

Step-by-step explanation:

Divide both sides by -20. If you divide by a negative, you have to switch the inequality sign. So now you have this for t:

t < 4

Draw a circle around 4 on a number line, but do not shade it in. Then everything below 4 is the right answer for the value of t.

Answer:

12.75

Step-by-step explanation:

The computation of the geometric mean of sqrt 77 and sqrt 343 is given below:

As we know that

Geometric mean = [tex]\sqrt{ab}[/tex]

where

a is the first number = [tex]\sqrt{77}[/tex]

And, the b is the second number = [tex]\sqrt{343}[/tex]

Now first we have to convert into a number

For a it, is = 8.78

And, for b, it is = 18.52

Now the geometric mean is

[tex]= \sqrt{8.78 \times 18.52}[/tex]

= 12.75
