USE THE SQUARE ROOT PROPERTY!!!!!

the sides of a square are reduced by 2 inches. the new area is 20 square inches. Set up and solve an equation to find the original length of the square

Answers

Answer 1

Answer:

Step-by-step explanation:

x = original length of one side

(x-2)² = 20 inches²

x-2 = ±√20 = ±2√5

x = 2±2√5

2-2√5 is an extraneous solution,

so x = 2±2√5 ≈ 6.47 inches

Find the value of x and find whether the angles or supplementary or complementary.

Answers

Answer:

1) x = 31

2) Both angles add up to be a supplementary angle (an angle who's sum is 180° altogether).

Step-by-step explanation:

1) Since both angles add up to be a supplementary,

→ equation 1 + equation 2 = 180

→ (3x + 25) + (2x) = 180

Solving by applying algebra will give the answer "x = 31".

Jack and his friends are going hiking next week. There are four trails they can hike: Grayson Pass, Giant’s Ridge, Three Summits, and Elderberry. To make a decision, they use a spinner divided into four colors. They spin it 60 times to check the fairness of their model and record the results in this table.
The relative frequency of the spinner landing on green is


The relative frequency of the spinner landing on blue is


The relative frequency of the spinner landing on yellow is


The relative frequency of the spinner landing on red is

Answers

Answer:

Step-by-step explanation:

The theoretical frequency would be 1/4, and if spun 60 times, 15/60.

The relative frequency is how many times it actually landed on each color.

So green is 6/60

Blue is 24/60

Yellow is 9/60

Red is 21/60

I don't know if they want these in their simplest form (sometimes the test says one way or the other), but here they are, reduced:

Green: 1/10

Blue: 4/10

Yellow: 3/20

Red: 7/20

Please let me know if you have questions, or if it's marking these answers wrong.

Answers

Answer:

$292.50

Step-by-step explanation:

Equation - A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2.5%/100 = 0.025 per year.

Solving our equation:

A = 260(1 + (0.025 × 5)) = 292.5

A = $292.50

The total amount accrued, principal plus interest, from simple interest on a principal of $260.00 at a rate of 2.5% per year for 5 years is $292.50.

Your Answer Should Be: A=$292.50

Here is Laila’s graph from the previous screen.

Write your own equation in the form y=​mx+b that could represent Laila’s graph.

Answers

Answer:

y=-1/3x+8

Step-by-step explanation:

There is no need for any specific answers, but here is one that could logically work out. Since the graph is going left/down, it has a negative slope, so -1/3 would be reasonable. The graph doesn't cross the origin and crosses above it, so this equation must have a positive 'b' value. In this case, I chose 8. y=-1/3+8 could represent Laila's graph.

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 6 inches.

Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 6) would represent a height of 6 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)

Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)

Answer:

  A. (0, 6), (1, 5.5), (2, 5), (3, 4.5), (4, 4), (5, 3.5)

  B. is a function

  C. is a function

Step-by-step explanation:

Both relations are functions.

A relation is NOT a function if the same input value maps to two different output values. Virtually any relation involving time as an input will be single-valued: a measure can only have one value at any given time (ignoring quantum physics).

__

A: If height decreases 1/2 inch per hour, then some ordered pairs could be ...

  (hours, inches) = (0, 6), (1, 5.5), (2, 5), (3, 4.5), (4, 4), (5, 3.5)

For each additional hour, 0.5 inches was subtracted from height.

__

B: There is only one output for each input, so the relation is a function.

__

C: Yes, the relation is still a function. There is still only one output value for each input value.

A block of iron has dimensions of 1 cm x 2 cm x 5 cm and has a
mass of 799
What is its density? (V=lxwxh)

Answers

Answer:

79.9 units

Step-by-step explanation:

Hi there,

Before solving this problem, it is important to know the formula:

D = [tex]\frac{m}{v}[/tex].

D = density

m = mass

v = volume

Since we are given the mass and volume, we can simply enter these values into the formula to find the density of the block.

D = [tex]\frac{799}{10}[/tex]

D = 79.9

Therefore, the density of the block of iron is 79.9 units. I wrote units since you did not specify the unit for the mass. Hope this answer and explanation helps.

A sample of 5 integers selected is shown. Does this sample represent the general rule for picking an integer from 1 to 25 in the population of integers from 1 to 1,000?

A.Yes - the sample is representative of the expected number of integers from 1 to 25 in a sample of 5 integers, which would be none or zero.
B. No - the sample is not representative of the expected number of integers from 1 to 25 in a sample of 5 integers, which would be at least 10.
