Answer:

125

Step-by-step explanation:

When you put 90 into 125 it is 72% of the number.

Answer:

1) 2/3, two triangle segments

2) 1/7, one triangle segment

3) 3/9, three triangle segments left

really, you could do this by subtracting the top number, the numerator, because these visual diagrams have the same bottom number, or denominator, but for now, just subtract the segments. hope this helps, good luck.

He made 2109$ He is rich rich

Answer: option d.

Step-by-step explanation:

We have the function:

y = f(x) = x^2  - 1

The output is 99 when y = 99, and the input is x.

Then we need to solve:

y = 99 = x^2 - 1

for x.

99 = x^2 - 1

99 + 1  =x^2

100 = x^2

√100 = x

10 = x

The correct option is d, input equals 10.

Answer:

57/12

Step-by-step explanation:

4 9/12

multiply 12 by 4 to get 48. then we add 48 and 9 to get 57. now we just have to put 57 over our original denominator, 12. so we get 57/12.

Answers:

a) Function

b) Domain = {3, -4, -3}

You won't type in the curly braces for the domain, but it's common to use them to indicate we're talking about a set.

========================================

Explanation:

We have a function because each item in the domain (blue oval) goes to exactly one item in the range (green oval). We don't have two arrows or more originating from one item in the domain. So each input leads to exactly one output.

The domain is the set of allowed inputs. So the domain is the set {3, -4, -3}. Those items are found in the blue oval. As your teacher instructs, you won't be typing in the curly braces, but it's common to see the domain listed as a set like this. Optionally you can sort the items from smallest to largest, but it's not necessary. This is because order doesn't matter in a set.

a.) Function

Answer:

58 weeks

Step-by-step explanation:

Water tank A = 522 - 4x

Water tank B = 696 - 7x

Where,

x = number of weeks

Equate both equations

522 - 4x = 696 - 7x

Collect like terms

522 - 696 = -7x + 4x

-174 = -3x

Divide both sides by - 3

x = -174/-3

x = 58 weeks

The amount of water in the two tanks will be the same in 58

weeks

Answer:

0.95

Step-by-step explanation:

Quarter = 0.25

Dime = 0.10

0.25+0.25+0.25= 0.75

0.10+0.10= 0.10

0.10+0.75 = 0.95

Answer:

0.04

Step-by-step explanation:

Given that :

Mean(m) = 150

Standard deviation (s) = 20

Find P(X<115)

Obtain the Zscore :

(x - m) / s

(115 - 150) / 20

P(X<115) = - 1.75

Using the Z probability calculator :

P(Z < - 1.75) = 0.040059

P(Z < - 1.75) = 0.04

Step-by-step explanation:

x²+7x+12

x²+4x+3x+12

y = -2

Step-by-step explanation:

10 -5y = 20       { subtract 10 from both sides}

  -5y = 20 - 10

  -5y = 10          {Divide both sides by (-5) }

    y = 10/-5

y = -2

Answer: y = -2

Step-by-step explanation:

10 - 5y = 20

Add 5y to both sides

10 = 5y + 20

Subtract 20 from both sides

-10 = 5y

Divide both sides by 5

y = -2

Answer:

D- 99 1/4 ; $992.50

Step-by-step explanation:

6 5/8 was the closing price of the bond. $6625 was the dollar amount. Therefore, the correct option is option B.

The final transaction price of a securities before the market formally shuts for regular trading is known as the closing price or cash value. Investors typically use closing prices as a benchmark for evaluating a stock's performance over the previous day, and they are widely used to create line graphs that show historical price fluctuations over time.

The stock price that after market closes may be impacted by dividends or stock splits; these are taken into account in the adjusted closing price. While in much lower quantities, the majority of stocks as well as other investment vehicles are traded after business hours. 6 5/8 was the closing price of the bond. $6625 was the dollar amount.

Therefore, the correct option is option B.

Answer:

y = 5/4x + 10

Step-by-step explanation:

First, we need to use point-slope form which is:

y - y₁ = m(x - x₁)

Now, we substitute the numbers:

y - 5 = 5/4(x - (-4))

y - 5 = 5/4(x + 4)

y - 5 = 5/4x + 5

y = 5/4x + 10

You can check by substituting the points into the equation:

5 = 5/4(-4) + 10

5 = -5 + 10

5 = 5

Answer:

Ace will work 88 problems correctly out of 100.

Step-by-step explanation:

Given that:

Ace worked out 22 problems out of his 25 activities

Ratio = 22:25

If the number of problems are 100, then x be the number of problems correctly solved by Ace.

Ratio = x : 100

The relationship is proportional.

22:25 :: x:100

Product of mean = Product of extreme

25x = 22*100

25x = 2200

[tex]\frac{25x}{25}=\frac{2200}{25}\\x=88[/tex]

Hence,

Ace will work 88 problems correctly out of 100.
