Can someone please help mee

Answer:

D

Step-by-step explanation:

you need to divide by 2. And you need to simplify a fraction.

Step-by-step explanation:

you will have 100% * 60 = X * 80 so X = 100% * 60/ 80

Answer:

75

Step-by-step explanation:

The answer is attached. I hope you are able to understand and it helps you. If you have doubt you can ask, I will repost the answer with proper explanation.

Answer:

25

Step-by-step explanation:

For these types of problems you'll need the Pythagorean theorem (woohoo..). This amazing formula looks like: a^2 + b^2 = c^2. The a and b in this formula are the legs of the triangle, the straight non-diagonal lines. The c stands for the hypotenuse which is the diagonal line.

Since you have both of the legs we can go ahead and plug that into our equation: 15^2 + 20^2 = c^2.

NOTE: It doesn't matter which leg you plug into which variable! Just make sure it's not c!

With exponents, it just means to multiply the number by itself. 15^2 is the same as 15(15). So, simplifying the equation, we get: 225 + 400 = c^2.

This part is pretty straightforward. I mean, unless you don't remember addition... Adding it together, you will get 625 = c^2.

This part kinda requires a calculator if you don't know all of your square roots. Luckily, this is a perfect root and goes into 25.

And that, my friend, is your answer. Hope this helped :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

The "key" to this is to recognize that the two lines have to be the same length, they put the drawing on it's side to make it harder to see that. :/  But another way to see this is that it's an isosceles triangle and you know the two legs that they are asking us about have to be the same length,  knowing that.. we can set the two expression equal to each other

3x - 10 = 2x

now solve for x

3x - 10 -2x = 2x - 2x  ( subtracting 2x from both sides )

3x - 2x - 10 = 0

x - 10 = 0

x - 10 + 10 = 0 + 10

x = 10    ( yay)

Answer:

We have the value as;

8x/5

Step-by-step explanation:

Here, we want to get the breakdown of the given expression

We have (x^2 - 9) as (x-3)(x + 3)

So we have;

2x/(x + 3) * (x-3)(x+3)/5 * 4/(x-3)

= 2x * 4/5= 8x/5

Answer:

5.56 m

Step-by-step explanation:

Circumference = 2πr

r is the radius, however the diameter is given. The radius is half the diameter. So the radius is:

1.8 ÷ 2 = 0.9

Circumference = 2 × π × 0.9

= 5.56 m ( in 3 significant figures )

Answer:

$86.40

Step-by-step explanation:

80 × .08 = 6.40

80 + 6.40 = $86.40

Answer: 2 & -2

Step-by-step explanation: it takes 2 units to get to 0 and then 2 more to get to -2  

Answer:

.53

Step-by-step explanation:

your diameter is .82,so divide it by two to get your radius

.82 / 2 = .41

A = [tex]\pi[/tex] r ^2

A = [tex]\pi[/tex] .41 ^2

A = .53

Answer:

0.53

Answer:72.25

Step-by-step explanation:

Answer and Step-by-step explanation:

The answer is A.

y = x + 2 and y = -2x + 4

This is because:

- The graph going from left to right matches the first equation, in which the graph has a slope of 1 and has a y-intercept at (0, 2).

- The graph going from right to left matches the second equation, in which the graph has a slope of -2 (Since it is going from right to left), and has a y-intercept at (0, 4).

Answer:

162 ft^3

Step-by-step explanation:

volume = area of base * height

V = 22 1/2 ft^2 * 7 1/5 ft

Change the mixed numerals into fractions.

V = 45/2 ft^2 * 36/5 ft

Multiply the fractions.

V = 45/2 * 36/5 ft^3

Switch the denominators.

V = 45/5 * 36/2 ft^3

Simplify each fraction.

V = 9 * 18 ft^3

V = 162 ft^3

Answer:

B

Step-by-step explanation:

The only diagram representing a function is B.

All the others fail rhe vertical line test. Each of the x values should have one y value assigned.

hi the answer is 29

Step-by-step explanation:

Answer:

29

Step-by-step explanation:

Answer:

y - 2x = 3

Step-by-step explanation:

Use the point-slope formula y - k = m(x - h), with h = 0, k = 3 and m = 2:

y - 3 = 2(x - 0), or

y - 3 = 2x, or

y - 2x = 3

Note that the given point, (0, 3), is the y-intercept of this line, and so we immediately know b in y = mx + b:  it is 3.

Answer:

m∡2 = 41°

Step-by-step explanation:

m∡2 = 180 - (90 + 49) = 180 - 139 = 41

Step-by-step explanation:

step 1. m + 7.02 = 6.32

step 2. m = -0.70. (subtract 7.02 from each side)
