Answers

Answer:

True

Step-by-step explanation:

5x + 2 = 17

Subtract 2 from both sides

5x = 15

Divide both sides by 5

x = 3

Plug this number into the next equation and see if it is true

10x + 4 = 34

10(3) + 4 = 34

30 + 4 = 34

34 = 34

This is a true equation, so the the answer is true.

Answer:

True

Step-by-step explanation:

This is true because the whole equation 10x + 4 = 34 is 2 times more than the other equation 5x + 2 = 17.

You can see that by multiplying the whole equation 5x + 2 = 17 by 2:

2(5x + 2 = 17)

To get:

10x + 4 = 34

So both equations are equivalent, which means that the answer is true.

The perimeter of the base of a square pyramid is 16 feet and it stands 20 ft tall. Calculate the volume.​

Answers

Answer: [tex]1706.67 feet[/tex]

Step-by-step explanation:

Formula: Volume = [tex]\frac{1}{3} \alpha^{2}h[/tex]

a is the length of the base's edge and h is the height. Since 16 is the length we would square it as it is the length, then we would multiply it by the height which is 20 ft.

Steps: Multiply

Volume = [tex]\frac{1}{3} \alpha^{2}h[/tex]

= [tex]\frac{1}{3} * 16^{2} * 20[/tex]

= [tex]1706.67 feet[/tex]

The diagonals of quadrilateral ABCD
intersect at E
. If EC=4, BD=12, AE=x,
and BE=y
, what values of x
and y
would prove that the quadrilateral is a parallelogram?

Answers

Answer:

Step-by-step explanation:

16 ae =x

The values of x

and y  that would prove that the quadrilateral is a parallelogram are 4 and 6 respectively.

Find the diagram attached. In order to prove that the quadrilateral is a parallelogram, we need to find the values of x and y that make the diagram a parallelogram.

From the parallelogram;

AE = EC and BE = EDBD = BE + EDAC = AE + EC

Given the following parameters

EC=4,

BD=12,

Since AE = EC, hence the measure of AE is 4.

Similarly, BD = BE + ED

BD = BE + BE

BD = 2BE

12 = 2BE

BE = 6 = y

Hence the values of x

and y  that would prove that the quadrilateral is a parallelogram are 4 and 6 respectively.

You are standing at the edge of a cliff. You look down with an angle of depression of 20 degrees and see a a dog at the bottom that is 130 feet away from where you're standing. What is the height of the cliff? Round your answer to the nearest tenth, and round only once.

Answers

Answer:

47.3feet

Step-by-step explanation:

The set up will give a right angled triangle.

The distance of the dog away from the cliff = 130 feet = adjacent side

Angle of depression = 20°

Height of the cliff = Opposite = x

Using the SOH, CAH, TOA trigonometry identity;

According to TOA;

tan theta = opposite/adjacent

tan 20 = x/130

Cross multiply;

x = 130tan20

x = 130(0.3639)

x = 47.3 feet

Hence the height of the cliff to the nearest tenth is 47.3feet

What is the probability, to the nearest hundredth, that A and B occur?

Answers

Answer:

0.43* 0.35 = 0.1505 or 0.15 after rounding

Step-by-step explanation:

Based on the probabilities of A and B occurring with conditions, the probability of A and B occurring is 0.15.

What is the probability that both A and B occur?

This can be found by the formula:

= Probability that A occurs if B occurs x Probability of B occurring if A occurs

Solving gives:

= 0.43 x 0.35

= 0.15

In conclusion, the probability is 0.15.

Maurice and his father are building a dog house. They are using long pieces of wood and cutting them into smaller pieces. They have a piece of wood that is 3.6 feet long and are cutting it into pieces that are each 0.75 feet. How many smaller pieces will they be able to make?

Answers

Answer:

4.8 smaller pieces

Step-by-step explanation:

Total length of wood = 3.6 feet

Length of each piece = 0.75 feet

How many smaller pieces will they be able to make?

Number of smaller pieces of wood = Total length of wood / Length of each piece

= 3.6 feet / 0.75 feet

= 4.8 smaller pieces

Number of smaller pieces of wood = 4.8

Select the correct answer. What is[tex]\sqrt{192}[/tex] in simplest form? A.32√3 B.3√8 C.8√3 D. 2√48

Answers

Answer:

C. 8√3

Step-by-step explanation:

Please mark me as brainlest!

Thanks!

48√2 in the simplest form of the expression √192.

Option D is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can simplify the √192 by factoring it into its prime factors:

192 = 2 × 2 × 2 × 2 × 2 × 3 × 3

Then, we can group the prime factors into pairs of two:

192 = (2 × 2) × (2 × 2) × (2 × 3) × 3

Simplifying each pair of factors under the square root gives:

[tex]\sqrt{192} = \sqrt{(2\times2)}\sqrt{(2\times2)}\sqrt{(2\times3)}\sqrt{3}\\= 4\times4\times\sqrt{6}\sqrt{3} \\= 16\sqrt{6}\sqrt{3}[/tex]

Finally, we can simplify the expression by multiplying the coefficients and combining the square roots:

[tex]16\sqrt{6}\sqrt{3} \\= 16\sqrt{18} = 16\sqrt{2\times3\times3} \\= 16\times3\sqrt{2} \\= 48\sqrt{2}[/tex]

Therefore,

48√2 in the simplest form of the expression √192.
