Answer:

70°

Step-by-step explanation:

n+20=90° [being a right angelled triangle]

or, n=90°-20°

therefore n=70°

I guess this is the answer but please confirm first.

Answer:

x=64°

................

=============================================================

Explanation:

Combining all of the angles shown in the diagram leads to 360 degrees. This is because there are 360 degrees in a full rotation.

Let's add up the angles shown and set the sum equal to 360. Keep in mind that the square angle marker represents 90 degrees (aka a right angle).

180+26+x+90 = 180

x+296 = 360

x = 360-296

x = 64

Answer:

∠TUX and ∠WXU

Step-by-step explanation:

Alternate interior angles are angles that lie on the inside of the parallel lines, but different sides.

∠TUX is on the left side.

∠YXU is on the right side.

Therefore, ∠TXU and ∠WXU are alternate interior angles.

Answer: see below

Step-by-step explanation:

Answer:

D) 54.9 cm^2

Step-by-step explanation:

I found the area of the circle wwith the formula A= πr^2

A= π•64

then I found the area of the square, 256

then I subtracted the area of the circle from the area of the square and got approx. 54.9

Answer:

the answere is y=543.2

Step-by-step explanation:

thats it

Answer:

<A = 45°

<B = 110°

Step-by-step explanation:

Sum of the interior angles of a triangle = 180°

Therefore,

(x + 65)° + 25° + x° = 180°

Solve for x

x + 65 + 25 + x = 180

Add like terms

2x + 90 = 180

2x = 180 - 90

2x = 90

x = 90/2

x = 45°

✔️x + 65 = 45 + 65 = 110°

<A = x = 45°

<B = 110°

Answer:

x = 16

Step-by-step explanation:

I could be wrong so sorry in advance lol but this is what I did:

I made the equation 3x + 3 = ((7x-10)/2)

I divided the 2nd equation by 2 so that it would be the same length as RZ.

after that, I got: 3x + 3 = 3.5x - 5

from there, i did basic algebra to get the answer 16

Answer:

3'6

Step-by-step explanation:

Answer:

Step-by-step explanation:

If you round it to the nearest whole number, then 17.526  becomes 18 because if the first digit after the decimal(in this case,5) is 5 or greater you round to the next whole number.

If you round it to the nearest tenth, it would result in 17.5, because if the second digit after the decimal (in this case, 2) is 5 or greater you round to the next tenth of decimal.

Hope this helps!

Answer:

Step-by-step explanation:

It can be rounded down to 17.5 if rounding to 1 decimal place. If you are rounding to the nearest whole number, you would round to 18.

Hope this helps :)

Answer:

The probability that the monthly mortgage is between 2300 and 3140 is: 0.23167

Step-by-step explanation:

Given

[tex]\mu = 2870[/tex] --- the average

[tex]\sigma = 470[/tex] --- the standard deviation

Required [Missing from the question]

Monthly mortgage is between 2300 and 3140

This is represented as:

[tex]P(2300 < x < 3140)[/tex]

This is calculated as:

[tex]P(a< x < b) = P(z_a < Z < z_b)[/tex]

[tex]P(2300< x < 3140) = P(z_b < Z < z_a)[/tex]

Calculate the z scores

[tex]x = 3140[/tex]

[tex]z = \frac{3140 - 2850}{470}[/tex]

[tex]z = \frac{290}{470}[/tex]

[tex]z = 0.6170[/tex]

[tex]x = 2300[/tex]

[tex]z = \frac{3140 - 2300}{470}[/tex]

[tex]z = \frac{840}{470}[/tex]

[tex]z = 1.7872[/tex]

So, we have;

[tex]P(2300< x < 3140) = P(1.1787 < Z < 0.6170)[/tex]

This is then calculated as:

[tex]P(a < Z < b) = P(Z < a) - P(Z <b)[/tex]

[tex]P(a < Z < b) = P(Z < 1.1782) - P(Z <0.6170)[/tex]

[tex]P(2300< x < 3140) = P(Z < 1.1782) - P(Z <0.6170)[/tex]

Using the z table:

[tex]P(Z<0.6170) =0.73138[/tex]

[tex]P(Z<1.7872) =0.96305[/tex]

[tex]P(2300< x < 3140) = 0.96305 - 0.73138[/tex]

[tex]P(2300< x < 3140) = 0.23167[/tex]

Answer:

Step-by-step explanation:

Given,

Base of the parallelogram = 10

Height of the parallelogram = 12

Therefore,

Area of the parallelogram = base × height

= 10 × 12

= 120

Hence,

Area of the parallelogram is 120 square units (Ans)

Step-by-step explanation:

Answer:

P(2 and B) = [tex]\frac{1}{24} = 0.0417[/tex]

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the events getting a 2 and the letter B are independents, so we find each separate probability and multiply them.

Probability of getting a 2:

8 possible values on the spinner, one of which is 2. So

[tex]P(A) = \frac{1}{8}[/tex]

Probability of getting a B:

6 possible values, two of which are B. So

[tex]P(B) = \frac{2}{6} = \frac{1}{3}[/tex]

P(2 and B)?

[tex]P(A \cap B) = P(A)*P(B) = \frac{1}{8}*\frac{1}{3} = \frac{1}{8*3} = \frac{1}{24} = 0.0417[/tex]

P(2 and B) = [tex]\frac{1}{24} = 0.0417[/tex]

Answer:

Width of rectangle = 5 inch

Length of rectangle = 2 inch

Step-by-step explanation:

Given:

Area of rectangle = 10 inch²

Length of rectangle = 2[Width of rectangle] - 8

Find:

Equation

Value of length and width

Computation;

Assume;

Width of rectangle = x

So,

Length of rectangle = 2[Width of rectangle] - 8

Length of rectangle = 2x - 8

Area of rectangle = Length × Width

10 = x(2x - 8)

2x² - 8x - 10 = 0

Divide by 2 from both side

x² - 4x - 5 = 0

x² - (5-1)x - 5 = 0

x² - 5x + x- 5 = 0

x(x - 5) + 1(x - 5)

x = 5 and x = -1

So,

Width of rectangle = 5 inch

Length of rectangle = 2x - 8

Length of rectangle = 2(5) - 8

Length of rectangle = 2 inch
