Answer:

The answer is 22

Step-by-step explanation:

Do Prime Factorization of 1260

(as shown in the picture I attached)

Prime factors of 1260 = 2, 2, 3, 3, 5, 7

Now to get the sum of the prime factors of 1260, you just have to add all the factors

2 + 2 + 3 + 3 + 5 + 7 = 22

Hope this helps!

Using the net below, find the surface area of the triangular prism.

Luden [163]

Answer:

Hi, there! The total surface area of that prism is 118 cm^2.

Step-by-step explanation:

The three rectangles on the side are called the lateral area, and they add up to 98(I'm assuming you know how to find the area of a 2d shape), and as for the triangles on the sides, you can just use the formula which is $b*h/2$ .

Hope this helps :)

Aaron found rhe length of the diagonal of a rectangle to be an irrational number. What could be the lenght of the diagonal

Amanda [17]

Answer:

See below

Step-by-step explanation:

It could be a positive square root l like √10 ( the number not being a perfect square).

He would have obtained this value from the application of the Pythagoras theorem. For example the length and width of the rectangle might have been 3 and 1 foot respectively, so the diagonal would have length √(3^2 + 1^2) = √10.

He could give an estimate of the length to nearest hundredth using his calculator. This would be 3.16 feet.

In hypothesis testing, if the null hypothesis has been rejected when the alternative hypothesis has been true, _____. a. a Type

lara31 [8.8K]

Answer:(c)

Step-by-step explanation:

Given : In a hypothesis testing the null hypothesis has been rejected when the alternative hypothesis has been true.

Find : to find that the given decision is create type I error , type II error or right decision has been taken

Step by step :

In hypothesis testing there are 2 types of error.

(1)Type I error :- if the null hypothesis is rejected when it is true, is known has Type I error .

(2)Type II error:- if the null hypothesis is accepted when alternative hypothesis is true, is known as type II error.

Since here null hypothesis has been rejected when alternative hypothesis has been true,i.e., the correct decision has been made

Hence option (c) is correct.

What is the answer and steps to do it 45 +5/6x =50

Nookie1986 [14]

Equation:- 45+5/6 x=50
1) Simplify both sides of the equation. 5/6 x + 45 = 50
2) Subtract 45 from both sides. 5/6 x + 45 − 45 = 50−45 5/6 x=5
3) Multiply both sides by 6/5.(6/5)*(5/6 x)=(6/5)*(5)x=6

SO, x=6.

Hope I helped.
