Are equilateral triangles a subcategory of rhombus?
Why or why not? Please explain, and no files please, or you will be reported.

Answers

Answer 1

Answer:

No.

Such a rhombus exists, but they aren’t always like that. A rhombus is made of two isosceles triangles.

A rhombus is a parallelogram where all of it’s sides are equal length

Ciara brought $240 to spend on gifts for her family. she found 8 identical statues at the gift shop. she had $72 leftover. how much did each statue cost?(please write an equation for the answer like 2 step equation)

Answers

Answer:

$21 each

Step-by-step explanation:

Since she had $72 left that means that she spent $168 so then you divide that by the 8 identical statues.

$240 - $72 = $168

$168/8 = $21

Answer:

$21

Step-by-step explanation:

Price of each statue = x

Price of 8 statues = 8x

Price of 8 statues plus money left over = 8x + 72

Original amount of money = 240

Equation:

8x + 72 = 240

Subtract 72 from both sides.

8x = 168

Divide both sides by 8.

x = 21

Answer: $21

Answer:

a(n+1) = a(n) + 9

Step-by-step explanation:

The terms just before and just after each are 9 more than the previous term or 9 less than the previous term.  In other words, the common difference is 9.

Thus, the recursive formula is a(n+1) = a(n) + 9

Find the surface area of the prism.



The surface area is_______
square meters.

Answers

total surface area is: 416 m^2
740 square meters

First you do 16 times 10 for the base(the square on the bottom), this equals 160.
Then you do 17 times 10 for sides. We have two of these so just add 170 plus 170 which equals 340.
Next use the formula A=bh/2 for the triangle. A=16(15)/2 this equals 240 but since we have two triangles then we don’t have to divide it.
Then add all of your numbers which are 240+160+340 and you get 740.

I hope this makes sense

Kelly likes to fish at the lake near her house. She caught 8 fish last week, measured them, and put them back in the lake. The lengths of the fish, in inches, are shown.

Assuming this data is representative of the fish in the lake, what is the mean length of the fish in the lake?

A.

B.

Write a numerical expression for 3 more than half of 16.

Answers

16 divideed by 2 =8 + 3

The value of numerical expression for 3 more than half of 16 is,

⇒ 3 + 1/2 (16)

⇒ 11

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 3 more than half of 16.

Now, We can write the numerical expression as;

Half of 16 = 1/2 (16)

And, 3 more than half of 16 is,

⇒ 3 + 1/2 (16)

⇒ 3 + 8

⇒ 11

Thus, The value of numerical expression for 3 more than half of 16 is,

⇒ 3 + 1/2 (16)

⇒ 11

Answers

Answer:

C

Step-by-step explanation

Since 1 2/3 is too large for the blank, and 0.153 is too small, we try C, which is 22%. Convert it to a fraction to make 11/50.  If you cross multiply, we would find out that 11/50 is a greater fraction than 2/11 and less than 1.42. Hence, we get C as our answer.

Answer:

C

Step-by-step explanation:

2/11 = 0.18

22% is equivalent to 0.22, which is greater than 0.18, but less than 1.42

Answer:

171 m

Step-by-step explanation:

Okay, so we have to find the area of all the shapes that make up the prism:

I'm going to start with the side rectangles:

5 x 7 = 35

There's 2 of them so:

35 x 2 = 70

Now let's go onto the side triangles:

4 x 6 = 24 (normally it would then be ÷ 2, but because there's 2 triangles, you don't have to do that)

Then we do the bottom rectangle:

6 x 7 = 42

So, adding them all together:

35 + 70 + 24 + 42 = 171

So the surface area of the prism is 171 m

hope this is right:)
