Can Someone Help Me Figure This Out I'm Completely Lost And This Is Due In Like An Hour, The Question

Answers

Answer 1

Answer:

GH = 4

Step-by-step explanation:

GH = AB due to congruency markings therefore

5y - 8 = 3y

-8 = =2y

4 = y

Answer 2

Answer:

GH=12

Step-by-step explanation:

You use what this other solution to the answer was. However, they did not include that GH is 3y, so while one y=4, 3y=12. Therefore, GH=12

Triangle GHK has an area of m square units. If the height of the triangle is increased to five times the current height, and the length of the base increased to four times the current length, what will be the area of the larger triangle?

Answers

Answer:

20m square units

Step-by-step explanation:

The area of a traingle  = bh/2............... Equation 1

Where b = lenght of the base, h = heigt of the triangle.

From the question,

The area of triangle GHK = m square units., let the base and the heigth of the triangle be x and y respectively

Therefore,

b = x, h = y

Substitute these values into equation 1

m = xy/2................... Equation 2

If the height of the triangle increase to five times the current height, and the length of the base increase to four times the current length.

Therefore,

height of the larger triangle = 5y, base of the larger triangle = 4x

Substitute these values into equation 1

Area of the larger triangle = (5y×4x)/2

Area of the larger triangle = 20xy/2................. Equation 3

Substitute equation 2 into equation 3

Area of the new triangle = 20m square units.

A backpack is on sale for 15% off the original price of $39.99. What is the sale price?

Answers

Answer:

33.99

Step-by-step explanation:

multiply the original by 100-the sale percentage

(100-15 = 85

.85x39.99

Answer:

$33.99

Step-by-step explanation:

We are given that we have 15%.

What this means is that we subtract 15% from 100%.

Doing that we get 1.00 - 0.15 = 0.85

Therefore the price equals $39.99 * 0.85

The final price is $33.99

Given a polynomial f(x), if (x − 3) is a factor, what else must be true?

f(3) = 0
f(−3) = 0
f(0) = 3
f(0) = −3

Answers

Answer:

A

Step-by-step explanation:

Recall that according to the Polynomial Remainder Theorem, if we divide a polynomial f(x) by a binomial in the form (x - a), then the remainder will be f(a).

And by the Factor Theorem, in order for a binomial (x - a) to be a factor of a polynomial f(x), the remainder must be 0. In other words, f(a) = 0.

We are given a polynomial f(x) and that (x - 3) is a factor.

Therefore, a = 3.

And since it is a factor, by the Factor Theorem, the remainder must be 0.

Therefore:

[tex]f(3)=0[/tex]

The answer is A.

After winning a soccer game, the coach took the team out for ice cream cones. He spent $21 on 12 single-scoop ice cream cones. If all the ice cream cones cost the same amount, what was the cost of one ice cream cone?

Answers

Answer:

Unitary cost= $1.75

Step-by-step explanation:

Giving the following information:

He spent $21 on 12 single-scoop ice cream cones.

To calculate the unitary cost, we need to use the following formula:

Total cost= number of units*unitary cost

Unitary cost= total cost / number of units

Unitary cost= 21 / 12

Unitary cost= $1.75

A paper container in the shape of a right circular cone has a radius of 3 inches and a height of 8 inches. Determine and state thr number of cubic inches in the volume of the cone, in terms of  π.​

Answers

Given:

Radius of the cone = 3 inches

Height of the cone = 8 inches

To find:

The volume of the cone, in terms of  π.​

Solution:

We know that, the volume of a cone is:

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

Putting [tex]r=3,h=8[/tex], we get

[tex]V=\dfrac{1}{3}\pi (3)^2(8)[/tex]

[tex]V=\dfrac{1}{3}\pi (9)(8)[/tex]

[tex]V=\dfrac{72}{3}\pi [/tex]

[tex]V=24\pi [/tex]

Therefore, the volume of the cone is [tex]24\pi[/tex].

Which color's observed frequency is closest to its expected frequency?
red
blue

O yellow

Answers

Answer:

Blue

Step-by-step explanation:

Expected frequency is:

red 10/40 = 1/4 = 0.25 = 25%

blue 10/40 = 1/4 = 0.25 = 25%

yellow 10/40 = 1/4 = 0.25 = 25%

green 10/40 = 1/4 = 0.25 = 25%

Observed Frequency is:

red 1/7 = 0.14 = 14%

blue 2/7 = 0.28 = 28%               √

yellow 4/7 = 0.57 = 57%
