find the area of the square

Answers

Answer:

100 sq units

Step-by-step explanation:

hypotenuse of the right triangle is the length of the square and we can find it by using the Pythagorean Theorem:

6² + 8² = c²

c² = 36+64

c² = 100

c = √100

c = 10

Area of square = 10² = 1--

Step-by-step explanation:

Based on historical data, your manager believes that 43% of the company's orders come from first-time customers. A random sample of 243 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is between 0.2 and 0.39?

Answers

Answer:

Following are the solution to the question:

Step-by-step explanation:

[tex]p = 0.43\\\\n = 243\\\\\sigma =\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.43 (1 -0.43)}{243}}=0.0013[/tex]

z-score for [tex]\hat{p}=0.2[/tex] will be:

z score for will be:

[tex]z=\frac{\hat{p}-p}{\sigma}=\frac{0.39 - 0.43}{0.0013}=-30.76[/tex]

[tex]P(0.2 <\hat{p}< 0.39) = P(-176.92 < z < -30.76)[/tex] using excel method to calculate the value.

Answers

Answer:

Step-by-step explanation:

Sum of angles of a triangle = 180

x + (180 - 105) + (180 -140) = 180

x + 75 + 40 = 180

x = 180 -75 - 40

x = 65

Find the value of x. 6 8 4 x

Answers

Answer:

3

Explanation:

4 is half of 8 on the right side, so that means X has to be half of 6, so it’s 3. Also, it couldn’t be 2 because it is too big, and it can’t be 4 because it isn’t the same length as the other 4, so it’s 3

The value of x in the figure which illustrates similar triangles is 3

How to determine the value of x?

The figure illustrates similar triangles.

This is represented by the following equivalent ratios

x : 6 = 4 : 8

Express as fraction

x/6 = 4/8

Multiply both sides by 6

x = 6 * 4/8

Evaluate the product

x = 3

Hence, the value of x in the figure is 3

The can shown has a diameter of 3 inches and a height of 5 inches. Find the lateral surface area of the can.

Answers

Answer:

Lateral surface area of can = 47 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of given can = 3 inches

Height of given can = 5 inches

Find:

Lateral surface area of can

Computation:

Radius of can = 3 / 2 = 1.5 inch

Lateral surface area of can = Lateral surface area of cylinder

Lateral surface area of cylinder = 2πrh

Lateral surface area of can = 2πrh

Lateral surface area of can = 2(3.14)(1.5)(5)

Lateral surface area of can = 47.1

Lateral surface area of can = 47 inch² (Approx.)

Answers

a) 288 m2

Explanation:
Ok so surface area is just adding up all the area of each faces. Just look at what I do below:

Area of the rectangular base:
10 • 6= 60

Area of the front triangle facing us:
1/2 • 12 • 10= 60
Multiply 60 by 2 cause there is still another similar triangle at the back- 60 • 2= 120

Area of the triangle facing right:
1/2 • 8 • 6= 24
Multiply 25 by 2 case there is still another similar triangle facing on other side(left)
24 • 2= 48

Add them all up together
60 + 120 + 48= 228

y-5x-2 ... Show your work.
A) (-4,-22)
B) (4; 6)
C) (-4; 6)
D) (4;18)
no links and pls show ur work

Answers

I’m not sure if you mistyped but if you meant y=5x-2 then here is your answer:

So the equation is y=mx + b

-2 is your b meaning that it is your y intercept so you can plot it on the y axis (0,-2)

Then your slope is 5. Since your slope is positive, in order to go to the left side you can change both the denominator and numerator into negatives. So 5/1 = -5/-1

Slope = rise/run

So each time you go down 5, you go to the left once. So if you go to -4, then you will have to go down 4 times as well so 4 x 5 = 20, so you go down 20 points. You are already at (0,-2) so if you go down 20 points then you are at (-4,-22)

Therefore the correct answer is (-4,-22)
