Answer:

The answer is B and C . If you need the method I used to find it, contact me via comments on brainly.

Answer:

B  and C

Step-by-step explanation:

on c i got exactly 25%

but on B i got 23% but B was the closest to 25% than A and D

Answer:

BC ≈ 13.7

Step-by-step explanation:

using the cosine ratio in the right triangle

cos51° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{8.6}{BC}[/tex] ( multiply both sides by BC )

BC × cos51° = 8.6 ( divide both sides by cos51° )

BC = [tex]\frac{8.6}{cos51}[/tex] ≈ 13.7 ( to 3 sf )

Answer: Choice B)  [tex]y \ge \frac{3}{4}x-3[/tex]

The boundary is the equation y = (3/4)x-3 which goes through (0,-3) and (4,0)

This boundary is a solid line. Since it's a solid line, we will involve "or equal to" as part of the inequality sign.

The shading above the boundary line indicates we'll also have "greater than" as part of the inequality sign.

So overall, the inequality sign is "greater than or equal to". That leads to choice B.

Answer:

eight to the power of 4 would be 8x8x8x8, 9 cubed would be 9x9x9 and 9^3, 17x17x17, 21x21x21x21x21 and 21^5, 7^2, 11x11x11x11

Step-by-step explanation:

Answer:

-18

Step-by-step explanation:

If you turn 2 1/4 into an improper fraction, you get 9/4

Turn -8 into an improper fraction, you get -8/1

Equation: 9/4*-8/1

You can cross cancel the 4 and the 8 so your equation becomes 9/1*-2/1 which becomes 9*-2

Multiply and you get -18 :)

Answer:

25 pi square yd OR rounded pi to 3.14: 78.5 square yd

Step-by-step explanation:

Use the formula volume of cylinder = base area × h to determine the value of the base area.

Diameter: 5 yd

Height: 4 yd

(5/2)^2 Pi x 4 = 25 pi square yd.

Answer:

78.5 yd

Step-by-step explanation:

= [tex]\pi[/tex]r²h

= (3.14)(2.5)²(4)

= (3.14)(6.25)(4)

= 19.625 x 4

= 78.5 yd

Answer:

2.8

Step-by-step explanation:

Answer:

2.8 is the MAD

6 is the mean

Answer:

9 is the greatest value

Step-by-step explanation:

As proportional relationship, the amount decreasing at a rate milligrams per hour can be written in expression P(t) = 500 + e⁻⁰²ˣ

In math, the relationships between two variables where their ratios are equivalent is known as proportional relationship.

Given that P(t) represent the amount of a certain drug, in milligrams, that is in the bloodstream at time t hours.

Here we have the rate at which the drug leaves the bloodstream proportional to the amount of the drug bloodstream.

The amount of the drug in the bloodstream can be modeled by dP/dt = kP, where k is a constant and t is time, in hours.

Here we need to find the expression.

Bloodstream = 500 milligrams

So, the expression for this proportional relationship is written as;

P(t) = 500 + e⁻⁰²ˣ

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

Answer:

coordinates of :   G = -9 , D = 9

Answer:

x = 4

Step-by-step explanation:

Given the points (4, - 1) and (4, 8)

Note the x- coordinates are 4 in both cases.

This indicates the line passing through the points is vertical with equation

x = c

where c is the value of the x- coordinates the line passes through. In this case 4, thus

x = 4 ← equation of vertical line

70 = 100 - 2•15 is 2 s.d.'s below the mean.

130 = 100 + 2•15 is 2 s.d.'s above the mean.

By the empirical rule,

Pr [70 ≤ X ≤ 130] = Pr [-2 ≤ Z ≤ 2] ≈ 95%

(where Z is normally distributed with mean 0 and s.d. 1)

Step-by-step explanation:

316+178 divided by 2427 (2639 plus 26383) - 373637/282637

Answer: No you cannot.

Step-by-step explanation:

They are different units and cannot be combined.

3. 5

Constant terms are terms with no variables attached to them, and will not change under any circumstances. A variable is typically denoted by a Latin Alphabet.

4. 4

The coefficient is the whole number found in front of the variable, typically being multiplied to it. In this case, you are solving for the coefficient that is found in front of g², which is 4.

5. -3c

The coefficient -3 is found at the 3rd term of the expression.

6. -12x & -17x ; 15y & 16y

Like terms are terms with the same variable as well as the same amount of variables. For example x² is not a like term of x, though both variables have x to signify them.

7. 3c

Unlike terms are terms that do not share at least one partner of the same amount of variables. c is a variable by itself with no other terms containing it, and so is your answer.
