Actually Welcome to the concept of Congruency.

Since here the congruency satisfied is SAS (side-angle-side)

hence the correct option is

D.) ∆HFE =~ ∆FHG

Answer:

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

Answer:

it's 8

Step-by-step explanation:

(10×1/5)^3=2^3=8

Answer:

The answer is 8!

Step-by-step explanation:

Subtract the like terms.  As you can see, the 10 in the numerator and denominator have the same base.  Therefore, you can subtract the exponents, which would be 10^1, or 10.  You would do the same for 5, which would be 5^-1, or 1/5.  You would then make this one fraction, the 10 and 5.  The fraction would be 10/5, or 2 once simplified.  Now, don't forget the outside parentheses!  You would do 2^3, and your final answer would be 8.  Hope this helps!

Answer:

Red is the correct answer

Step-by-step explanation:

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: 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:

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:

y=10x+20

y=5x+100

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

Step-by-step explanation:

Answer:

3 feet

Step-by-step explanation:

l = length

w = width

p = l + l + w + w

l = 4

w = x

2l + 2w = 14

2(4) + 2w = 14

8 + 2w = 14

2w = 6

w = 3

Answer:

The ball holds 113.0 cubic inches of air

Step-by-step explanation:

Firstly we need to know the shape of the ball

A ball is spherical in shape

So to know the number of cubic inches, we have to find the volume of air in the ball

Mathematically, we can do this by finding the volume of the ball using the formula for the volume of a sphere

The formula for the volume of a sphere is ;

V = 4/3 * pi * r^3

in this case, r = d/2 = 6 /2 = 3 inches

where r is the radius of the ball and d is the diameter of the ball

So, substituting these values , we have

V = 4/3 * 3.14 * 3^3 = 113.0 cubic inches

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) .

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.

Answer:

108 mm^3

Step-by-step explanation:

the formula for a right rectangular pyramid is lwh/3, so if you multiply 6, 6, and 9, you'll get 324

324/3=108

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.
