Answer:

the answer is

a^2 + b^2 = c^2

5^2 + b^2 = 13^1

25 + b^2 = 169

b^2 = 144

b = 12  

or

The ladder is the hypotenuse, and the two legs are distance from the wall and height of the wall. If it is moved 5 feet away, it will reach 12 feet high, for 5^2+12^2=13^2.

Harlie's expression is 10n-4, which expression(s) are equivalent to Charlie's? Hint: Plug in three set values for "n" in each of the expressions to see if they are equivalent (ex. Plug in 2, 3, and 4 in each of the expressions).

Answers

Answer:

[tex]10n - 4 = 2(5n - 2)[/tex]

Step-by-step explanation:

Given

Expression: 10n - 4

Required

Select equivalent expressions

This question requires options. Since none is provided, I'll answer the question generally.

[tex]10n - 4[/tex]

Express 10 as 2 * 5 and 4 as 2 * 2

[tex]10n - 4 = 2*5n - 2 * 2[/tex]

Factor out 2

[tex]10n - 4 = 2(5n - 2)[/tex]

Hence: 2(5n - 2) is equivalent to 10n - 4.

Answers

Answer:

C

Step-by-step explanation:

First we need to find W. You can do that by dividing 47.25 by 5.25.

47.25 / 5.25 = 9

So W = 9.

Now we do both equations to see which one is correct.

Equation A: 3/4 × 9 = 6 3/4, which is true.

Equation B: 9 - 10.24 = -1.24, which is also true.

Therefore, both equations give you the same solution, C.

If the pointer in the figure is spun twice, find the probability that the pointer lands on green (G) both spins


Urgent please help!:(

Answers

the green space takes up 1/8 of the board
there’s two so it’s 2/8
2/8 times 2/8 = 4/64 or 1/16

The probability that the pointer lands on green (G) both spins is 1/9.

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have spinner having

3 yellow portion, 2 Green portion and one Red portion.

If the spinner spun twice then the probability that the pointer lands on green (G) both spins

= 2/6 x 2/6

= 1/3 x 1/3

= 1/9

Thus, the required probability is 1/9.

A chocolate pastry cost Rs.26 and a fruit pastry cost Rs.18 Jenny buys both
these pastries together for Rs. 500 how many of each did she buy ?

Answers

Required Answer:-

Let's assume the no. of chocolate pastry bought = x

and the no: of fruit pastry bought = y

➣ Cost of 1 chocolate pastry = Rs 26

➣ Cost of x chocolate pastry = Rs 26x

➣ Similarly, cost of fruit pastry = Rs 18 y

➣ It is given that the total cost = Rs 500

Therefore, Rs 26x + Rs 18 y = Rs 500

If we assume x = 4 and y = 22 , then

26 x 4 + 18 X 22 = Rs 500

104 + 396 = 500

⇝ No. of chocolate pastries bought = 4 ✔

⇝ No. of fruit pastries bought = 22 ✔

The missing dimension of the prism is A

because the volume of the rectangular prism equals the product of the sides, we have:

V = (x - 1)(x - 3)A

but V = x³ - 8x² + 19x - 12

=> x³ - 8x² + 19x - 12 = (x - 1 )(x - 3)A

⇔ x²(x - 1) - 7x(x - 1) + 12(x - 1) = (x - 1)(x - 3)A

⇔ (x² - 7x + 12)(x - 1) = (x - 1)(x - 3)A

⇔ (x² - 3x - 4x + 12)(x - 1) = (x - 1)(x - 3)A

⇔ (x - 3)(x - 4)(x - 1) = (x - 1)(x - 3)A

⇒ A = x - 4
