Find The Total Surface Area Of This Prism Where The Cross-section Is An Isosceles Triangleplease Help

Answers

Answer 1

Answer:

620 cm²

Step-by-step explanation:

First I'll describe the net. There are 3 rectangles and 2 triangles. The triangles are identical and 2 out 3 of the rectangles are the same.

So, we know that the two similar rectangles have measurements of 13cm x 10cm. So, that's 130 cm² for one such rectangle. Add the other one and we get 260 cm².

The bottom rectangle has dimensions of 10cm x 24 cm, or 240 cm². Add that to our previous total and we'll get 500 cm².

On to the triangles. Now, we know that 1. these are isosceles triangles, and 2. they have a height of 5 cm. We can pretend to cut them in half at their highest point, which would give us 4 triangles with height 5 and length 12. Now, if you put two identical triangles together, it's a four-sided shape, and you can just multiply length by width. Let's do that.

Now we have 2 rectangles, each with width 5 and length 12. Calculate the area for each, and now we have 2 rectangles with area 60 cm². Add them together....120cm².

Add that to our previous total, and we'll get 620 cm². That should be the surface area of your prism :D

Q base and height of a parallelogram 12 cm and 8 cm respectively find its area....

please give me fast answer.​

Answers

Answer:

The area of a parallelogram is: 96 cm²

Step-by-step explanation:

Given

The base of a parallelogram b = 12 cmThe height of a parallelogram h = 8 cm

To determine

The area of a parallelogram A = ?

Using the formula to calculate the area of a parallelogram

A = bh

here

b is the base of a parallelogram h is the height of a parallelogram

so substituting b = 12 and h = 8 in the equation

A = bh

A = 12×8

A = 96 cm²

Therefore, the area of a parallelogram is: 96 cm²

Answers

Answer:

Option B is the correct option.

Step-by-step explanation:

Given the expression

[tex]\frac{\sqrt[3]{x^5}}{\sqrt[3]{x^7}}[/tex]

Apply radical rule:

[tex]\frac{\sqrt[n]{a}}{\sqrt[n]{b}}=\sqrt[n]{\frac{a}{b}}[/tex]

so

[tex]\frac{\sqrt[3]{x^5}}{\sqrt[3]{x^7}}=\sqrt[3]{\frac{x^5}{x^7}}[/tex]

Apply radical rule:

[tex]\frac{x^a}{x^b}=x^{a-b}[/tex]

so

   [tex]=\sqrt[3]{\frac{1}{x^2}}[/tex]         ∵  [tex]\frac{x^5}{x^7}=x^{5-7}[/tex]

   [tex]=\frac{1}{x^{\frac{2}{3}}}[/tex]

Therefore, option B is the correct option.

Pencils are sold in boxes of 10. Erasers are sold in boxes of 14. A teacher wants to buy the same number of pencils and erasers. Work out the smallest number of boxes of each item she should buy.

Answers

Answer:

We have;

7 pencil boxes and 5 eraser boxes

Step-by-step explanation:

To find the smallest number of boxes that can be bought, what we simply do is to find the lowest common multiple of the content of each of the boxes

hence, we are going to find the lowest common multiple of 10 and 14

The lowest common multiple of 10 and 14 is 70

So the smallest number of pencil boxes that can be bought is 70/10 = 7

The smallest number of eraser boxes would be 70/14 = 5

At the dance, the ratio of the number of girls to boys is 7:5. If there are 36 more girls than boys, how many girls were at the dance? How many boys were at the dance?

Answers

9514 1404 393

Answer:

126 girls90 boys

Step-by-step explanation:

The difference is 7-5 = 2 "ratio units", corresponding to a difference of 36 dancers. Then each "ratio unit" stands for 36/2 = 18 dancers.

There are 7×18 = 126 girls.

There are 5×18 = 90 boys.

_____

You could solve this by writing some equations:

  g/b = 7/5

  g -b = 36

Then you could substitute for g:

  (36+b)/b = 7/5

  36/b +1 = 2/5 +1 . . . . expand the fractions

  36/b = 2/5 . . . . . . . . . subtract 1

  b = (5/2)(36) = 90 . . . multiply by 5/2b

  g = 36+90 = 126

solve.

Compute the standardized test statistic, χ 2, to test the claim σ 2 = 25.8 if n = 12, s 2 = 21.6, and α = 0.05.

Answers

Answer:

[tex]t^2=9.2[/tex]

Step-by-step explanation:

From the question we are told that

Standard Deviation [tex]\sigma=28.8[/tex]

Sample space [tex]n=12[/tex]

[tex]s^2= 21.6[/tex]

Generally the equation for test statistics is mathematically given by

[tex]t^2=frac{(n-1)*s^2}{\sigma^2}}[/tex]

[tex]t^2=\frac{(12-1)*21.6}{25.8}[/tex]

Therefore the standardized test statistics
