Can someone one help me out my grads are bad

Answer:

26

Step-by-step explanation:

The triangle equals 180 degrees the two measurements we already have is 90 degrees (the right angle) and 64 degrees.

90+64=154 and 180-154=26.

So 26 is your answer because 90+64+26=180

The resulting expression equivalent will be x^2 - 4x - 8

Given the expression

x−9x−4+x^2−x+5x−4

We are to find an equivalent expression

Simplify to have:

x−9x−4+x^2−x+5x−4

x^2 +x−9x - x + 5x - 4 - 4

x^2 - 4x - 8

Hence the resulting expression equivalent will be x^2 - 4x - 8

Step-by-step explanation:

Answer:

(1,000 * (100 + 12))/100 = 1,120 - 1,000 = 120 turtles/ per year

Step-by-step explanation:

The exponential function which can be use to identify the monthly growth is,

⇒ y = 1000 (1.12)¹²ⁿ

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

We have to given that;

That's population of turtles in a lake is estimated at 1,000.

And,  The population projected to increase 12% per year.

Hence, The exponential function which can be use to identify the monthly growth is,

⇒ y = 1000 (1 + 12/100)¹²ⁿ

⇒ y = 1000 (1 + 0.12)¹²ⁿ

⇒ y = 1000 (1.12)¹²ⁿ

Thus, The exponential function which can be use to identify the monthly growth is,

⇒ y = 1000 (1.12)¹²ⁿ

Step-by-step explanation:

Answer:

x = 12

Step-by-step explanation:

The angles are supplementary and add up to 180

(8x - 20) + (8x + 8) = 180

Combine like terms

16x - 12 = 180

add 12 to both sides

16x = 192

Divide both sides by16

x = 12

Answer:

No

Step-by-step explanation:

Answer:

{-4, 3}

Step-by-step explanation:

To find "solutions," you must set this function equal to zero:

y = -7(x - 3)(x + 4) = 0

and then set each factor equal to 0 separately and solve each resulting equation for x:

x - 3 = 0 yields x = 3, and

x + 4 = 0 yields x = -4

Answer:

Rate of change is used to mathematically describe the percentage change in value over a defined period of time, and it represents the momentum of a variable. The calculation for ROC is simple in that it takes the current value of a stock or index and divides it by the value from an earlier period.

Answer:A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable, then. rate of change=change in ychange in x. Rates of change can be positive or negative.

Answer:

D

Step-by-step explanation:

Since the side length of the square is (2x+5), and squares have equal sides, then you have to do (2x+5)(2x+5). You would get 4x^2+20x+25. That means the answer is D.

Answer:

y+1=-3(x+2)

Step-by-step explanation:

point-slope form is the formula y-y1=m(x-x1), where (x1, y1) is a point and m is the slope

we are given a point (-2, -1) and a slope of -3

all we really need to do is substitute the given into the formula

remember: since the formula gives subtraction, we're going to be subtracting, even though we have negative numbers

substitute -2 as x, -1 as y and -3 as m

y--1=-3(x--2)

we can simplify this equation:

y+1=-3(x+2)

Answer:

t = 0.0475p

Step-by-step explanation:

From the options provided, the answer would be ...

t = 0.0475p

Lets say Tonia's paycheck is 25,000 she needs to pay 5% of this to her 401k, meaning she should have 95% left

25,000 * 0.95 = 23,750

Now, 5% of this remainder goes to income tax which would be...

23,750 * 0.05 = 1,187.5

Now if we use the formula and plug in 25,000 for p which is Tonia's paycheck we see that we get the same income tax amount. Therefore, we know it is the correct formula.

t = 0.0475 * 25000

t = 1,187.5

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

Explanation:

The first thing to do is to swap the positions of the x < 3 and the x > -1

So you'll end up with x > -1 and x < 3

Now focus entirely on x > -1. Swap the left and right sides, and also swap the inequality sign. So we end up with -1 < x

That means the "x > -1 and x < 3" is the same as "-1 < x and x < 3"

From here, we collapse the two inequalities to form the compound inequality -1 < x < 3

We can say "x is between -1 and 3, excluding either endpoint".

Answer:

Volume of sphere A = 128x (Approx.)

Step-by-step explanation:

Given:

Radius of sphere A = 2 x Radius of sphere B

Volume of sphere B = 16x

Find:

Volume of sphere A

Computation:

Volume of sphere = (4/3)(π)(r)³

Volume of sphere B = (4/3)(π)(r)³

16x = (4/3)(π)(r)³

16x = (4/3)(22/7)(r)³

16x = (88/21)(r)³

Radius of sphere B = 1.56∛x Approx.

Radius of sphere A = 2 x Radius of sphere B

Radius of sphere A = 2 x 1.56∛x

Radius of sphere A = 3.12∛x Approx.

Volume of sphere A = (4/3)(π)(r)³

Volume of sphere A = (4/3)(22/7)(3.12∛x)³

Volume of sphere A = (88/21)(30.37∛x)

Volume of sphere A = 127.27x

Volume of sphere A = 128x (Approx.)

Answer:

C. The scale factor is less than one.

Step-by-step explanation:

By definition, similar triangles have equal angles and proportional corresponding side lengths. Thus, A, B, and D are all mutually exclusive, leaving C the only possible answer. Upon further inspection, the scale factor is indeed greater than one (each side length is scaled by a factor of two, which is large than one)

Answer:

16 is probability

Step-by-step explanation:

Answer:

x = -2

Step-by-step explanation:

30=-5(6x+6)

step 1 distribute the -5

-5 * 6x = -30x

-5 * 6 = -30

we now have 30 = -30x - 30

step 2 add 30 to each side

30 + 30 = 60

-30 + 30 cancels out

we now have 60 = -30x

step 3 divide each side by -30

-30x/-30 = x

60 / -30 = -2

we're left with x = -2

A study with a sample that is very different from the population is biased

The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.

Population density = number of people / the area they occupy

Given data ,

A study with a sample that is very different from the population is J. biased.

In statistical terms, bias refers to any systematic error or deviation from the true value that can occur in a study. When a study is biased, the results may not be representative of the population and may not be generalized other settings.

Results from a research may be skewed if the sample chosen is considerably different from the population. Both experimental and observational research may experience this. As a result, alternatives F and G do not offer sufficient details to assess the study's objectivity.
