Choose the equation that shows the relationship of 80%, x, and 100.

Answer:

d

Step-by-step explanation:

-4+5n=18+3n

step 1 add 4 to each side

5n=22+3n

step 2 subtract each side by 3n

2n=22

step 3 divide each side by 2

n=11

Answer:

80 cents i think if i did my math right

Step-by-step explanation:

80 times 5 is 400

Answer:

A. n

Step-by-step explanation:

n/4 + n/4 + n/4 + n/4 = 4n/4 = n

On solving the expression, n/4 + n/4 + n/4 + n/4 , we get n.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.  Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have the following expression -

n/4 + n/4 + n/4 + n/4

We can write -

n/4 + n/4 + n/4 + n/4

n/4(1 + 1 + 1 + 1)

4 x n/4

n

Therefore, on solving the expression, n/4 + n/4 + n/4 + n/4 , we get n.

Answer:

It is not.

Step-by-step explanation:

The formula of a right triangle is "[tex]a^{2}+b^{2} =c^{2}[/tex]" where c is the hypothenuse (the longest side of the triangle) if we replace the formula with the values we will get

  "[tex]30^{2} +122^{2} =125^{2} \\900 + 14884 = 15625\\15784\neq 15625[/tex]

Answer:

If you were solving the right triangle, it would be:

m∠A = 46°

m∠B = 44°

m∠C = 90°

AB = 32

BC ≈ 23

AC ≈ 24

Step-by-step explanation:

To solve this right triangle, you can use trigonometric ratios to solve for the sides. To find the angle measures:

m∠A = 46° (given)

m∠B = x

m∠C = 90° (given)

180 - (46 + 90) = x

180 - 136 = x

44 = x

m∠B = 44°

To find the side measures, you can use tangent, sine, cosine, and the Pythagorean Theorem.

Recall that:

tangent = opposite side/adjacent side

sine = opposite side/hypotenuse

cosine = adjacent side/hypotenuse

So:

sin46 = BC/32

BC = 32 (sin46)

BC ≈ 23

tan46 = BC/AC

AC = BC/tan46

AC = (23.01887361...) (tan46)

AC ≈ 24

Answer:

a. 150 degrees

b. 210 degrees

c. 12π

d. 5π

e. 7π

f. 36π

g. (I'm assuming the shaded region is CAB) 15π

Answer:

The answer to the question is b+3 (if you need an equation)

Step-by-step explanation:

−4x+5−13x+39=180

Step 1: Simplify both sides of the equation.

−4x+5−13x+39=180

−4x+5+−13x+39=180

(−4x+−13x)+(5+39)=180(Combine Like Terms)

−17x+44=180

−17x+44=180

Step 2: Subtract 44 from both sides.

−17x+44−44=180−44

−17x=136

Step 3: Divide both sides by -17.−17x

−17

Answer:

1009

Step-by-step explanation:

0,25 x 2018 = 504,5

20,18 x 25 = 504,5

504,5 + 504,5 = 1009

Answer:

1,009

Step-by-step explanation:

[tex] \frac{25}{100} \times 2018 = 504.5[/tex]

[tex] \frac{2018}{100} \times 25 = 504.5[/tex]

[tex]504.5 + 504.5 = 1009[/tex]

Answer

Input= 5

Output= 120

Step-by-step explanation:

The input goes up by 1, so m=5

The output shows how many hours there are in that many days so blank=120

Answer

output for m is 5

Step-by-step explanation

- multiply the input by a number to get the output

- to get the number to multiply it by you can divide a given out put by the input

( 24/2) = 12

- notice patterns

input- output

Step-by-step explanation: becuase i got 100 on quiz

Step-by-step explanation:

The first important details are given at the start, where the beginning amount of snow is 12 inches. This is a positive number.

Then, the next sentences tell us that the snow melts at a pace of 2 inches for an x number of days.

This can be represented by -2x because the word "melts" indicates a negative value.

From this, the equation can be made :)

Answer:

Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.

Step-by-step explanation:

Formula for the simple interest is,

Interest = [tex]\frac{P\times r\times t}{100}[/tex]

Here, P = Principal amount

r = rate of interest  

t = Duration of investment

Let Phyllis invested amount (at 5.25% rate of interest) = $x

Therefore, Interest on this amount,

Interest = [tex]\frac{5.25\times x}{100}[/tex]

             = $0.0525x

If he invested the rest amount $(13000 - x) at the rate of 5%,

Interest earned on this amount = [tex]\frac{(13000-x)\times 5\times 1}{100}[/tex]

                                                    = $(650 - 0.05x)

Interest earned on total amount = $672

Therefore, $0.0525x + $(650 - 0.05x) = $672.5

0.0025x + 650 = 672.5

0.0025x = 22.5

x = $9000

Rest amount = 13000 - 9000

                     = $4000

Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.
