Answer:

B

Step-by-step explanation:

Combine Like terms

Answer:

The answer is letter B

Step-by-step explanation

Simply combine like terms in which

-2x^2 + 7x^2 = 5x^2

8x + 4x = 12x

-9 + 2 = 7

So we come up with the answer of the option letter B

Answer:

350

Step-by-step explanation:

629= A+S

A-71 = S

629 = A+A-71

700=2A

A=350

Answer:

0.5 < x < 16.5

Step-by-step explanation:

For a triangle (by the triangular inequality theorem), we know that the sum of any two sides must be larger than the other side.

When we have a triangle and we know two sides, let's define the measures of these sides as S1 and S2.   (such that S2 > S1)

By the first property, we will have that S1 + S2 > S3

Where S3 is the third side, the one that we do not know.

But there is also a lower restriction, given by:

S2 - S1 < S3 < S1 + S2

This is because we also must have:

S1 + S3 > S2

and

S2 + S3 > S1

We can rewrite both of these to get:

S2 - S1 < S3

S1 - S2 < S3

Because S2 > S1, the first inequality is more restrictive, so we need to use that one.

Then we get the inequality:

S2 - S1 < S3 < S1 + S2

Ok, in this case, the shorter side is 8.0 then:

S1 = 8.0

And the longer side is 8.5, then:

S2 = 8.5

And the third side is x, S3 = x

Replacing those in our inequality, we get:

8.5 - 8.0 < x < 8.5 + 8.0

0.5 < x < 16.5

This is the range of possible sizes for side x.

The distance of the jungle gym to swing is 120 feet.

We have given that the diagram

we have to find the distance between jungle gym and swings is,

suppose that x is shorter length then the hypotenuse is 2x and  [tex]x\sqrt{3}[/tex]

is the longer length

By using the Pythagoras formula we have

The length of CA is,

[tex]CA=60(2)=120[/tex]

Therefore the distance of the jungle gym to swing is 120 feet.

Answer:

Four minus the product of one and a number x is 4−(1×x) .

Step-by-step explanation:

Given : Expression 'Four minus the product of one and a number x'.

To find : Write the expression in algebraic form ?

Solution :

Writing the expression as,

The product of one and a number x is written as 1×x .

Four minus the product of one and a number x is written as 4− (1×x)

Re-write the expression in simplest form is 4−x .

Therefore, Four minus the product of one and a number x is 4−(1×x) .

Volume of a cylinder = area of base x height:

50.24 x 3 = 150.72 ft^3

Answer:

150 ft³

Step-by-step explanation:

base = circle..................base area = area of the circle = πr².

to get the radius of the circle, we substitute from the formula.

let π be 3.142

3.142 × r² = 50.24.............................. 3.142r² = 50.24

divide both sides by 3.142 to get r² = 15.99....................find the square root of 15.99 to get r = 3.999.

VOLUME = πr²h

                = 3.142 × 3.999 ×3.999 × 3 = 150.72 ft³

This is another way of doing it.

Answer:

C

Step-by-step explanation:

we should set the equations based on what we know using y=mx+b

in the first set, we have m=5 and the +b as 100. This gives y=5x+100

in the second, we  m=20  and the +b of 10. This gives y=20x+10

I belive C would match this. Hope this helps!

Answer:

2/13

Explanation:

The bag has 6 red, 3 green, 4 blue.

Total marbles = 13

Probability of getting blue the first time would be 4/13 because 4 of the 13 total marbles are blue

Because you're not putting back the first marble, the total would go down to 12, so the probability of getting red the second time would be 6/12 or 1/2

The probability that the first marble is blue and the second marble is red = (4/13)(6/12) = 2/13

Answer:

12, 2 and 10

Step-by-step explanation:

(1)

b - 4 = 8 ( add 4 to both sides )

b = 12

(2)

y + 7 = 9 ( subtract 7 from both sides )

y = 2

(3)

16 = n + 6 ( subtract 6 from both sides )

10 = n

x ≈ 12.22

Step-by-step explanation:

SOH CAH TOA(Tangent = opposite side/adjacent side)

tan (48°) = x/11

=> x = tan (48°) × 11

=> x ≈ 12.22

Answer: 9 L

Step-by-step explanation:

Given

The dimension of the rectangular container is [tex]40\times 30\times 25\ cm^3[/tex]

It is filled with [tex]\frac{3}{5}[/tex] of the height

Water present in the container

[tex]\Rightarrow 40\times 30\times 25\times \dfrac{3}{5}\\\\\Rightarrow 18000\ cm^3[/tex]

Also, [tex]1\ L=1000\ cm^3[/tex]

[tex]\therefore 18,000\ cm^3=18\ L[/tex]

Now, half of the water is poured out

So, half is left

[tex]\Rightarrow \dfrac{18}{2}=9\ L[/tex]

Thus, 9 L of water is left in the container

Answer:

D.   150°

Step-by-step explanation:

∠X and ∠W are supplementary

Let a = m∠X

Then 5a = m∠W

m∠X + m∠W = 180

a + 5a = 180

6a = 180

a = 30

m∠W = 5a = 5(30) = 150°
