4. Please answer! I’ll give brainliest! Please show evidence:))

Answers

Answer:

G = 50

H = 80

I = 50

Step-by-step explanation:

Angle in a triangle is equal to 180. This means that we will equal all the angles to 180

2x + 2x + 4x-20 = 180

8x - 20 = 180

8x = 180 + 20

8x = 200

x = 200 / 8

x = 25

G = 2 * 25 = 50

I = 2 * 25 = 50

H = 4 * 25 - 20

H = 100 - 20 = 80

Maya and Reginald are installing hardwood flooring. Maya can install flooring in a room in 4 hours. Reginald can install flooring in a room in 3 hours. How long would it take them if they worked together?

Answers

Answer:

1 hour 42 minutes approx

Step-by-step explanation:

Given data

Mayas work rate= 1/4 room per hour

Reginald work rate= 1/3 room per hour

Let the total time taken for both of them be T

Hence their combined work rate

1/4+1/3= 1/T

3+4/12=1/T

7/12=1/T

T= 12/7

T= 1.7 hours

Hence it will take them 1 hour 42 minutes approx

Mallory is on a budget and wants to determine which cereal is a better buy. A 10-ounce box of Cereal A costs $2.70 and a 13-ounce box of Cereal B costs $3.64. The store is selling each cereal in 15 ounce boxes. Which cereal is cheaper and by how much?

Answers

Answer:

Cereal A is cheaper by $0.15

Step-by-step explanation:

Cost of a 10-ounce box of Cereal A = $2.70

So,

Cost of a 1-ounce box of Cereal A = [tex]\frac{2.70}{10}=\$0.27[/tex]

Cost of a 15-ounce box of Cereal A = [tex]0.27(15)=\$4.05[/tex]

Also,

Cost of a 13-ounce box of Cereal B = $3.64

So,

Cost of a 1-ounce box of Cereal B = [tex]\frac{3.64}{13}=\$0.28[/tex]

Cost of a 15-ounce box of Cereal B = [tex]=0.28(15)=\$4.2[/tex]

Here,

Cost of a 15-ounce box of Cereal B - Cost of a 15-ounce box of Cereal A = [tex]4.2-4.05=\$0.15[/tex]

Therefore,

Cereal A is cheaper by $0.15

Write the slope-intercept form of the equation of a line with a slope of -5/8 that passes through the point (-14,6)

Answers

Answer:

y = -5/8x - 11/4

Step-by-step explanation:

Since we already know the slope which is -5/8. This will be the m in the equation.

To find the y-intercept, plug the coordinates into the equation, which is

y= -5/8 + b

6 = -5/8(-14) + b

6 = 35/4 + b

= -11/4 = b

MARKING BRAINLIEST TO FIRST PERSON WHO ANSWERS!!! ALSO UPPING POINTS TO 25

Answers

Answer:

Approximately 460 ft

Step-by-step explanation:

In any question where we have:

A right triangleAn given angle, andA given side

And we're asked to find:

A missing side

We're gonna be using some trigonometry. The first question we've gotta ask is what we're looking for, and how the angles and sides relate to that. We're given:

The angle of elevation, 49°The distance to the base, 400 ft

And we're looking for:

The height of the hill, which I'll call h.

How do our sides relate to the angle? Well, the 400 ft side is adjacent to 49°, and the side h is opposite. From SOH-CAH-TOA, we can see that the last trig function, tangent, is equal to opposite/adjacent. Let's turn this into an equation to bring it all together:

[tex]\tan{49^\circ}=h/400[/tex]

Solving for h, we find that

[tex]h=400\tan{49^\circ}\approx400(1.15)=460[/tex]

So the heigh of the hill is approximately 460 ft.

Education researchers are interested in the workload expectations of freshmen at a local university. Since all of the freshmen are randomly placed into freshman seminar classes, the researchers randomly select 3 freshman seminar classes and survey all of the students within those classes. Which sampling method was used?

cluster sampling
simple random sampling
stratified random sampling
systematic random sampling

Answers

Answer: Cluster Sampling

Step-by-step explanation: I just took this test and got it correct :)

If the researchers choose three freshmen seminar classes at random and poll every pupil in those classes. The Cluster Sampling method was applied. Option A is correct.

What is cluster sampling?

In the probability sampling technique known as cluster sampling, you split a population into groups, such as districts or schools, and then randomly choose a sample from among these groups. Ideally, each cluster should be a small representation of the population as a whole.

When studying large, dispersed populations, cluster sampling is most effective since interviewing every individual would be expensive, time-consuming, and sometimes impossible.

By using cluster sampling, it is possible to create smaller, more comparable clusters that represent the population being studied.

Thus, the researchers choose three freshmen seminar classes at random and polled every pupil in those classes. The Cluster Sampling method was applied. Option A is correct.

-5Z = 55

What is Z?
Pls help

Answers

Answer:

z = -11

Step-by-step explanation:

-5Z = 55

to find z, divide each side by -5

[tex]\frac{-5Z}{-5} = \frac{55}{-5}[/tex]

z = -11

Answer:

Z = -11

Step-by-step explanation:

When dealing with variables, you want to get it alone so it instantly equals the number.

Since Z is being multiplied by -5, you're going to divide -5 because that's the opposite of multiplying--but you have to do it on both sides, not just the one.

Note that when you're dividing or multiplying a negative and positive number, the result with ALWAYS be negative!

-5Z = 55

/-5 /-5

Z = -11

Just in case, we'll plug in -11 for Z and see if it works.

-5(-11) = 55

Note again that when you're multiplying two negatives it cancels out the negative and makes the answer positive!

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that Abigail paid $62.00 for 8 friendship bracelets. Each bracelet cost an equal amount.

Cost of 8 friendship bracelets = $62.00

Therefore,

Cost of 1 friendship bracelets = $62.00/ 8

Cost of 1 friendship bracelets = 7.75

The cost of 1 friendship bracelets is $7.75
