Answer:

115

Step-by-step explanation:

200 - (11+83+21) = 85 and so 200 - 85 is 115

Answer:

False

Step-by-step explanation:

(4/5) / 8 does not equal 2/5. It would be 1/10.

Answer:

G. 12 cm

Step-by-step explanation:

Length of one leg of right triangle = a = 9 cm

Length of hypotenuse = c = 15 cm

Length of the other leg = b = ?

Applying pythagorean theorem, c² = a² + b², we have:

15² = 9² + b²

15² - 9² = b²

144 = b²

b = √144

b = 12

Answer:

3/8 + 1/4 is 5/8 and 1/10+4/5 is 1

Step-by-step explanation:

convert 1/4 to 2/8 and add to 3/8 to get 5/8

convert 4/5 to 9/10 and add to 1/10 equals 10/10 which is also 1

Answer:

9/10 (and 5/8 for question in title)

Step-by-step explanation:

To add fractions, you need to make a common denominator, which you can have a common denominator of 10.

To do this, multiply the numerator (4) and the denominator (5) by 2. You will get 8/10.

Now you can add them together: 8/10 + 1/10 = 9/10

I don't know if you wanted the question in the title answered too so here:

Same thing; common denominator. Use 8. Multiply 1 by 2 and 4 by 2. You get 2/8.

Add: 3/8 + 2/8 = 5/8

Answer:

9:16

Step-by-step explanation:

If there are 9 dogs and 7 cats and you need to know the total number of cats and dogs add the numbers together (16) and put the number of dogs in front of it (9). So the answer is 9:16

Answer:

9:16

Step-by-step explanation:

because he ratio of cats to dogs is 9:7, so that means the 9 is how many dogs their are, 9 + 7= 16, making 9:16 (i'm wrong i'm positive i might be right)

Answer:

A is the answer

Step-by-step explanation:

Answer:

U (-10,-7)

V ( -10,-1)

w (-1, -9)

Step-by-step explanation:

So you are lucky I just did this unit lol so i got the answer

When doing any rotation around the origin, only one number changes integers if it is 90 degrees, in this case rotating 90 degrees will cross the y axis.

This means the y value will remain the same but the integer for the x values will switch.

So the new values are:

U (-10,-7)

V ( -10,-1)

w (-1, -9)

i hope this helps!

pls give thx and brainliest. ;)

Answer:(-2,8)

Step-by-step explanation:The inequality −2<x<8 means "all numbers between −2 and 8." In interval notation, we express this as (−2,8). Notice that we use parentheses to show that the numbers −2 and 8 are not included.

Answer:

Below.

Step-by-step explanation:

In a right triangle:

sin x = opposite side / hypotenuse

cos x = adjacent side / hypotenuse

tan x = opposite side / adjacent side

In this triangle the hypotenuse = 12 and the adjacent side = h

so we use cos 47

cos 47 = h / 12

h = 12 cos 47

h = 8.2 cm.

Answer:

40%

Step-by-step explanation:

As a Fraction your answer would be [tex]\frac{48}{120}[/tex].

However we are looking for it as a percentage.

In order to calculate, this you can simply find 10%, and 5% of 120.

10% = 12

5% = 6

48 is divisible by 12, therefore 48 / 12 = 4  

Giving you your answer which is 40%.

Answer:

252 B

Step-by-step explanation:

45 + 18 + 189

Answer:252

Step-by-step explanation:

Answer:

0.193

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

The volume of a rectangular prism is:

[tex]V=\ell wh[/tex]

Since the prism has a square base, each side length being 2, this means that both the length and width of our prism is 2. Therefore:

[tex]V=(2)(2)h=4h[/tex]

So, we can write:

[tex]V=4h[/tex]

The height h increases at a rate of about 8 inches or 8/12 = 2/3 feet per minute.

So, after t minutes, the height will be 2/3(t) feet. Thus, we can substitute:

[tex]\displaystyle V=4\Big(\frac{2}{3}\Big)t=\frac{8}{3}t[/tex]

We want to find after how long it will be until the volume is 64 cubic feet. So, V = 64:

[tex]\displaystyle 64 = \frac{8}{3} t[/tex]

Solve for t:

[tex]\displaystyle t=\frac{3}{8}(64)=3(8)=24\text{ minutes}[/tex]

The correct answer is A.

Answer: C

Step by step explanation :

Answer:

-1/2, or -0.5

Step-by-step explanation:

Slope = delta y/delta x

In this situation, you would do.

0. 5 - 1 / 0.25 - (-0.75)

0.5 - 1 = -0.5

0.25 -(-0/75) = 1

-0.5 / 1 = slope

-0.5 = slope

or

-1/2 = slope

Hope this helps!

The answer is the first option - leaf.

Answer:

the answer is stem.

Step-by-step explanation:

i know this because i am on the same question and there are only two answers so if the other answer was wrong it means this one has to be right.

To solve the problem we will firstly rearrange the given expressions to get like terms together.

like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

If we subtract 9x^2+7x-2 from 8x−10, then we will get [tex]-9x^2 +x -8[/tex].

Given to us

we know to subtract an expression from another we need to find the like terms of both expressions to carry out the mathematical operation.

therefore,

[tex](8x-10) - (9x^2+7x-2)\\\\=8x-10 - 9x^2-7x+2\\\\= -9x^2 +8x-7x-10+2\\\\= -9x^2 +x -8[/tex]

Hence, if we subtract 9x^2+7x-2 from 8x−10, then we will get [tex]-9x^2 +x -8[/tex].
