Answer:

the answere is y=543.2

Step-by-step explanation:

thats it

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.

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:

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:

25.13 centimeters

Step-by-step explanation:

Answer:

The length of the rectangle is 25 cm, while the width is 5 cm.

Step-by-step explanation:

Given that the length of a rectangle is five times its width, to find its length and width, knowing that the perimeter of the rectangle is 60 cm, the following calculation must be performed:

(5X x 2) + (X x 2) = 60

10X + 2X = 60

12X = 60

X = 60/12

X = 5

5x5 = 25

Thus, the length of the rectangle is 25 cm, while the width is 5 cm.

Step-by-step explanation:

[tex] {x}^{2} + 10x + 16 = 0 \\ factors : 2 \: and \: 8 \\ = > {x}^{2} + 2x + 8x + 16 = 0 \\ x(x + 2) + 8(x + 2) = 0 \\ (x + 8)(x + 2) = 0 \\ hence \\ x = - 8 \: and \: - 2 \\ = > A. -8,-2[/tex]

Answer:

E

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:

69.36

Step-by-step explanation:

Multiply 289 with 24 and divide the result by 100

289 × 24 ÷ 100 = 69.36

Step-by-step explanation:

Step-by-step explanation:

complementry

since the angle 1 and 2 both measures 90⁰

Answer: Choice 2 Adjacent and Choice 4 Supplementary

Step-by-step explanation:

Here, we are given four choices, and I will be defining each of them.

-----------------------------------------------------------------------------------------------

We can see from the figure given

Both angles are 90°, so ∠1+∠2=90+90=180°

Which is supplementary.

We can see from the figure given

Both angles share a common arm and vertex

Which is adjacent

Answer:

TE = 12

Step-by-step explanation:

Given:

TE = 4 + 2x

EV = 4x - 4

The diagonals of the figure bisects each other. This means that:

TE = EV

4 + 2x = 4x - 4

Collect like terms

2x - 4x = -4 - 4

-2x = -8

Divide both sides by -2

x = -8/-2

x = 4

✅Find TE:

TE = 4 + 2x

Plug in the value of x

TE = 4 + 2(4)

TE = 4 + 8

TE = 12

Step-by-step explanation:

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: see below

Step-by-step explanation:

The shape is a trapezoid

Base 1 (BH) is 10

Base 2 (QA) is 14

Height is 5

Area

[tex]A=\frac{base_{1} +base_{2} }{2} h[/tex]

[tex]A=\frac{10+14}{2} *5\\A=12*5\\A=60[/tex]

Find distance between QB and HA

[tex]D=\sqrt{(x_{2} -x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}[/tex]

Q( -4,4)  B (-2,9)

[tex]D=\sqrt{(-2--4)^{2}+(9-4)^{2} } \\D=\sqrt{2^{2} +5^{2} } \\D=\sqrt{29}[/tex]

Perimeter

[tex]P=10+14+2\sqrt{29} \\P=24 +2\sqrt{29} \\P= 24+10.77\\P=34.77[/tex]
