Answer:

length of each side=√81

=9 cm

Answer:

9cm

Step-by-step explanation:

a square has 4 equal sides, so to find out the area you do width x height

the area is 81cm², which means that the side length is 9cm as 9 x 9 = 81

Answer:

X=60°

Y=50°

Step-by-step explanation:

Triangles must equal 180° when you add all angles together.

Triangle with angle X

To find the value of Y takes a few more steps, but it isn't hard!

Angle Y is on a line, which equals 180° just like a triangle.

We know X=60°, but we don't know what the blank angle equals.

We use the same steps as we did when finding X

We know that the blank angle=70° and that X=60°

Since the line equals 180, we add the two angles and then subtract from 180, just like before!

Answer:

x = 134 degrees

Step-by-step explanation:

The two angles are alternate interior angles, therefore they equal.

I hope this helped!

It can definitely be a bit tricky to remember all of the different types of angles! But let's see what we've got here.

Our given measures/variables, 134 and x, are both on the inside of the parallel lines (clue: INTERIOR). Then, we can see that they are on opposite sides (clue: ALTERNATE). Therefore, these are alternate interior angles.

Alternate interior angles are congruent, which means that x = 134 degrees.

Hope this helps!! :)

Answer:

The rate of simple interest is 0.125, or 12.5%.

Step-by-step explanation:

If the man must repay $750 after 4 years on a $500 loan, the simple interest would be ($750-$500), or $250.

The simple interest formula is i = p*r*t.  Solving this for the interest rate, r, yields

        i

r = ----------

       p*t

and so, with i = $250, p = $500 and t = 4 yr, we find r as follows:

         $250

r = ----------------- = 0.125

         $500*4

The rate of simple interest is 0.125, or 12.5%.

Calculate it in the way of Divide

Answer:

Step-by-step explanation:

By the Isosceles Triangle Theorem, angle O and angle M are congruent because the sides across from each of these angles are congruent. therefore, O = M = 4y - 15. Since, by the Triangle Angle-Sum Theorem all the angles of a triangle have to add up to equal 180 AND angle O and angle M are the same:

7y + 4y - 15 + 4y - 15 = 180 and

15y - 30 = 180 and

15y = 210 so

y = 14. Plug 14 in for y in 7y and get that

∠N = 98°

Answer:

7000

Step-by-step explanation:

Given the equation :

L=-250t+7000

L = amount owed after t months of repayment.

From the equation given, we could deduce that it is a linear equation of the form :

y = bx + c

Where, b = - 250 is the slope = fixed amount paid per month and it's negative because the amount owed will reduce with each payment made.

c = intercept, which is the value of L when t = 0

This will give amount borrowed :

L=-250t+7000

At t = 0

L = - 250(0) + 7000

L = 7000

Answer:

The statue is 10cm tall in Kia's drawing.

Step-by-step explanation:

We know the statue is 80ft tall, as Bob's drawing was 1cm to 5ft and his drawing was 16cm tall. 16 x 5 = 80ft.

Because the new scale is 1cm to 8ft, you divide the 80ft tall statue with 8, and that leaves you with a 10cm tall replica statue.

Answer:

10 cm

Step-by-step explanation:

According to the question,

~The product of 10 and a number is 3 less than the number.

Let us suppose the number as n. Writing it in the form of an equation,

→ 10 × Number = Number - 3

→ 10n = n - 3

Answer:

144 feet

5 seconds

Step-by-step explanation:

a.

we want the maximum (or the vertex)

-64/-32= 2

-16*2²+64*2+80=144

b.

Here we want the point in which the y=0

In other words, we want the x-intercept

-16x²+64x+80= -16(x-5)(x+1)

so we have

(5,0) and (-1,0)

A) the maximum height of the apple is 144 feet. B) it will take 1 second for the apple to reach the ground.

How to determine How many seconds will it take for the apple to reach the ground

a. To find the maximum height of the apple, we need to determine the vertex of the parabolic equation. The vertex represents the maximum point of the parabola.

The equation for the height of the apple is given as h = -16t^2 + 64t + 80.

To find the t-value at the vertex, we can use the formula t = -b / (2a), where a, b, and c are the coefficients in the equation.

In this case, a = -16 and b = 64. Substituting these values into the formula:

t = -64 / (2 * -16)

t = -64 / -32

t = 2

So, the apple reaches its maximum height at t = 2 seconds.

To find the maximum height (h), we substitute the value of t = 2 into the equation:

h = -16(2)^2 + 64(2) + 80

h = -64 + 128 + 80

h = 144

Therefore, the maximum height of the apple is 144 feet.

b. To find the time it takes for the apple to reach the ground, we set h = 0 in the equation and solve for t:

0 = -16t^2 + 64t + 80

We can factor this equation or use the quadratic formula. Let's use the quadratic formula:

t = (-b ± √(b^2 - 4ac)) / (2a)

In this case, a = -16, b = 64, and c = 80. Substituting these values:

t = (-64 ± √(64^2 - 4(-16)(80))) / (2(-16))

t = (-64 ± √(4096 + 5120)) / (-32)

t = (-64 ± √9216) / (-32)

t = (-64 ± 96) / (-32)

We have two possible solutions:

t1 = (-64 + 96) / (-32) = 1

t2 = (-64 - 96) / (-32) = 5

Since the apple was launched upward, we consider the positive solution t1 = 1.

Therefore, it will take 1 second for the apple to reach the ground.

Answer:

The F-value is approximately 4.57

Step-by-step explanation:

The given parameters are;

The number of oceanfront homes in the sample, n₁ = 21 homes

The standard deviation of the selling prices, s₁ = $45,600

The number homes in the sample of homes one to three blocks from the ocean, n₂ = 18 homes

The standard deviation, s₂ = $21,330

The level of significance, α = 0.01

The F-test is given as follows;

[tex]F = \dfrac{s_1^2}{s_2^2}[/tex]

Therefore, we get;

F = 45,600²/21,330² ≈ 4.57

The F-value ≈ 4.57

The critical value from the F-table = 1.86236.

In this exercise we have to use the knowledge about force to calculate the critical force, in this way we find that:

[tex]F-value: 4.57[/tex]

We know that the information given by the text is:

The F-test is given as follows:

[tex]F=(S_1^2)/(S^2_2)[/tex]

So we have:

[tex]F=(45.600^2)/(21.330^2)=4.57\\[/tex]
