I struggled with these as u can see, but pls answer all 3 questions and show how you set all the problems up (ill be giving brainliest)

Answer: C

Step-by-step explanation:

First set greater than 300 since Zack has to make more than 300 to make a profit. The equation is the amount he makes (n) -  cost of supplies ($32.50). He is completing 4 rooms so multiply (n - 32.5) with 4.

The equation would be 4 (n - 32.5)>300

Now to solve for n, divide 4 on other sides, then add 32.5 to both sides.

Answer:

A. $2.00

B. $26.99

Step-by-step explanation:

0.5 x 49.99 = 24.995

49.99 - 24.995 = 24.995

0.08 x 24.995 = 1.9996 and round to the nearest hundredth

24.995 + 1.9996 = 26.9946

round to the nearest hundredth

Answer:

Part a: 1.9996

Part b: 26.9946

Step-by-step explanation:

STEP 1:

Find the unit rate (1% of 49.99). You should get 0.4999. Then, multiply 0.4999 by 50. You should get 24.995.

STEP 2:

Find the unit rate of 24.995. You should get 0.24995. Then multiply 0.24995 by 8. You should get 1.9996 (answer for part a).

STEP 3:

Add 1.9996 to 24.995. You should get 26.9946 (answer to part b).

Answer:

c

Step-by-step explanation:

3/12= 1/4=0.25

Answer:

C

Step-by-step explanation:

step 1

Address input values.

Input values:

The fraction number = 3/12

step 2

Write it as a decimal

3/12 = 0.25

0.25 is the decimal representation for 3/12

For Percentage Conversion :

step 1

To represent 0.25 in percentage, write 0.25 as a fraction

Fraction = 0.25/1

step 2

multiply 100 to both numerator and denominator

(0.25 x 100)/(1 x 100) = 25/100

25% is the percentage representation for 3/12

Answer:

I think it should be [tex]24x^{2}[/tex]

Step-by-step explanation:

When the question said area of the cube, I think it was supposed to be surface area, which would [tex]6a^{2}[/tex] where a is the length of one edge. Given that the length of one edge is 2x, we would plug in 2x to the equation to get[tex]6*(2x)^{2}[/tex] which would become [tex]24x^{2}[/tex].

Answer:

x = 2

Step-by-step explanation:

141x + 50 + 4x = 340

=> 145x + 50 = 340

=> 145x = 290

=> x = 2

Hoped this helped.

Simplify both sides of the equation

Subtract 50 from both sides

Divide both sides by 145

[tex] = > \frac{145x}{145} = \frac{290}{145} [/tex]

x=2

Answer:

  0.5 < x < 16.5

Step-by-step explanation:

The third side of the triangle must be longer than the difference of the other two sides:

  x > (8.5 -8.0)

  x > 0.5

And it must be shorter than their sum:

  x < (8.5 +8.0)

  x < 16.5

The third side must be in the range ...

  0.5 < x < 16.5

_____

These limits are a direct consequence of the triangle inequality, which requires the sum of the two shortest sides exceed the length of the longest side.

Answer:

the constant is 1. 9/9 is the same as 1. so 9hours over 9 lawns is 1.

Answer:

[tex]a_n=-8+(n-1)-7[/tex]

Step-by-step explanation:

General arithmetic sequence formula: [tex]a_n=a_1+(n-1)d[/tex]

where [tex]a_1[/tex] = first term, and d = common difference.

The first term is -8

And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.

To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula

General formula: [tex]a_n=a_1+(n-1)d[/tex]

We have [tex]a_1=-8[/tex] and d = -7

So the formula to find the nth term would be

[tex]a_n=-8+(n-1)-7[/tex]

Answer:

8.93

Step-by-step explanation:

Answer:

the answer is 8 and 13/14, or 8.93

Step-by-step explanation:

because of PEMDAS, we solve the numbers in the parenthesis first.

2 x 7 = 14.

next, we divide 125 by 14.     125 / 14 =     8 and 13/14

in decimal form, that is 8.93 (rounded up)

Answer:

1.7

Step-by-step explanation:

You do rise over run or y/x to find your answer. You go over 6 and up 10 to get from the lower point to the one on top. 10/6=1.666667 and rounded will be 1.7

Step-by-step explanation:

[tex]sa = 2\pi(r)(h) + 2\pi{(r) }^{2} [/tex]

[tex]sa = 2\pi(5)(2) + 2\pi{(5) }^{2} [/tex]

[tex]sa = 20\pi + 50\pi[/tex]

[tex]sa = 70\pi[/tex]

Answer:

f(x)=208^0.3x

Step-by-step explanation:

Think of this as a graph. You start out with 208 caribou, which is your y intercept, as it is there when the growth is 0.

The generic formula fr an exponential equation is a^x.

A represents your initial value. In this case, its 208

x represents the growth. In this case, it's 0.3%.

Your equation should be f(x)=208^0.3x

Answer: Sarah does not have enough money to purchase the TV.

Explanation: The total price is $395.91.

Answer:

No

Step-by-step explanation:

10% of 415

= 1/10 of 415

= 1/10 * 415

= $41.5

415 - 41.5 = $ 373.5

6% of 415

= 6% * 415

= $24.9

∴ $373.5 + $24.9 = $398.4

∴ Sarah cannot buy the TV as she is $ 8.4 short.

it is closest to B

Answer:

x = 4

Step-by-step explanation:

55x + 10 = 230

=> 55x = 230 - 10

=> 55x = 220

=> x = 4

Therefore, x = 4.

Hoped this helped.

Answer:

x= 4

Step-by-step explanation:

solving equation step-by-step.

55x + 10 = 230

Subtract 10 from both sides.

55x + 10 − 10 = 230 − 10

55x = 220

Divide both sides by 55.

55x/55 = 220/55

x= 4

Our Answer: x= 4

Answer:

The number of hours a student should spend on their homework to expect a 94 on the quiz.

Answer:

7

Step-by-step explanation:

I don't completely understand what you were asking, but if you were counting by 7's, 91 would be after 84 instead of just 90.

Answer:

7

Step-by-step explanation:

7x14=91, so 1 is not a multiple of 90. Don't really understand tho, plz comment if this is not what you meant.
