If the volume for 3-D polyhedra A is 200 cm3 and the volume for 3-D polyhedral B is 800 cm3, how many times bigger is the volume of pyramid B than pyramid A? A. 0.4% B. 4% C. 40% D. 400%

Answers

Answer 1

Answer:

Answer:

400%

Step-by-step explanation:

Given :

The volume for 3-D polyhedral A is 200 cubic cm.

The volume for 3-D polyhedral B is 800 cubic cm.

To Find: how many times bigger is the volume of pyramid B than pyramid A?

Solution:

Since we are supposed to find how many times bigger is the volume of pyramid B than pyramid A.

⇒ $\frac{\text{Volume of Polyhedral B}}{\text{Volume of Polyhedral A}} * 100$

⇒ $(800)/(200) * 100$

⇒ $4 * 100$

⇒ $400\%$

Thus Option D is correct.

Hence the volume of pyramid B is 400% times bigger than pyramid A.

Answer 2

Answer: You can use the volume of pyramid B divided by volume of pyramid A and multiply 100%. That is 800/200*100%=400%. So the answer is D. 400%.

I'm looking at the top at 79.9 angle. I'm 100ft away. What's the height of the building?

Answers

To solve this, notice that you have the angle component (I will call this a) and the x-component (the distance of you from the building) of a trig formula, and you are looking for the y-component. We will use the tangent formula, since this incorporates the angle, x, and y components.

1. Write the formula

tan(a) = y ÷ x

2. Rewrite to include the known values.

tan(79.9) = y ÷ 100

3. Solve for the unknown variable, y.

tan(79.9) × 100 = y ÷ 100 × 100

tan(79.9) × 100 = y

4. A fancy step that I call the "flip flop."

y = tan(79.9) × 100

5. Use a calculator to find the value (make sure the calculator is in "degree" and not "radians" mode).

y = 561.3968

6. Round the number as is appropriate for this problem.

Have a great day!

so this is a trig problem

so you have a right triangle
base=100 ft
from wher you are standing, it is a 79.9 angle to the top
we want to find the height of the tower or the opposite side
the base is the adjacent side so you are looking for o/a or tan(79.9) since you know one of the sides so therefor
tan(79.9)=h/100
evaluate tan(79.9)
tan(79.9)=5.61396
5.61396=h/100
multiply both sides by 100
561.396=h
round to tenths place
561.4
the height=561.4 ft

Sixty percent of Company A’s employees are considered top performers. Fifty five percent of Company A’s employees are in a rigorous training program. Assuming these two statements are true are most of Company A’s employees in the rigorous training program considered top performers?

Answers

Answer:33 %

Step-by-step explanation:

Given

60 % of company A's employees are considered top performer

55 % of company A's employee are in a rigorous training program.

Now Company A's employees in the rigorous training program considered top performer are $0.60* 0.55=0.33$

That is 33 % of employee is in rigorous training and top performers.

not exactly. there are still 40 percent of the employees that are not top performers. for all you know those 40 percent could make up the majority of the employees in the training program

74 3/5 + 19 2/3 = Please Explain

Answers

Ok 74 $(3)/(5)$
So 19 $(2)/(3)$

= 373/5 + 59/3

= ((373 × 3) + (59 × 5)) / (5 × 3)

= (1119 + 295) / 15

= 1414/15

= 1414/15

= 94 4/15

74 3/5 + 19 2/3
74+19= 93
for 3/5+2/3 we need a common denominator which in this case would be 15 (the product of the two already existing denominators)
3x3=9 (the 3s are first numerator and the second denominator) so the first fraction is 9/15
5x2=10 (the first denominator and the second numerator) so the second fraction would be 10/15
9+10=19 (the numerators in both fractions) so it's 19/15 which we convert to a mixed numeral which is 1 4/15
93+1 4/15=94 4/15

hope this helps :)

Which of the following is not equivalent to cos pi over 5 1. Cos negative pi over 5 2. Cos 9pi over 5 3. Cos 4 pi over 5 4. Cos 11 pi over 5

Answers

Answer:

The expression that is not equivalent to $\cos ((\pi)/(5))$ is:

3. $\cos((4\pi)/(5))$

Step-by-step explanation:

We are asked to find which of the expression is not equivalent to:

$\cos ((\pi)/(5))$

$\cos((-\pi)/(5))$

We know that:

$\cos(-\theta)=\cos(\theta)$

Hence, we get:

$\cos((-\pi)/(5))=\cos((\pi)/(5))$

Hence, option: 1 is incorrect.

$\cos((9\pi)/(5))$

We know that:

$\cos((9\pi)/(5))=\cos( 2\pi-(\pi)/(5))$

As we know that:

$\cos(2\pi-\theta)=\cos(\theta)$

Hence, we have:

$\cos((9\pi)/(5))=\cos((\pi)/(5))$

Hence, option: 2 is incorrect.

$\cos((11\pi)/(5))$

We know that:

$\cos((11\pi)/(5))=\cos( 2\pi+(\pi)/(5))$

As we know that:

$\cos(2\pi+\theta)=\cos(\theta)$

Hence, we have:

$\cos((11\pi)/(5))=\cos((\pi)/(5))$

Hence, option: 4 is incorrect.

$\cos((4\pi)/(5))$

We know that:

$\cos((4\pi)/(5))=\cos(\pi-(\pi)/(5))$

As we know that:

$\cos(\pi-\theta)=-\cos(\theta)$

Hence, we have:

$\cos((4\pi)/(5))=-\cos((\pi)/(5))\neq \cos ((\pi)/(5))$

Hence, option: 3 is the answer.

If two lines are parallel, which statement must be true?A. Their slopes are reciprocals.
B. Their slopes are opposites.
C. Their slopes are equal.
D. Their slopes are negative reciprocals.

Answers

I believe the correct answer from the choices listed above is option C. If two lines are parallel, their slopes are equal. Having equal slopes mean that the rise and run of the points of the lines are the same. Parallel lines do not intersect even when extended infinitely.

Answer:

C. Their slopes are equal.

Step-by-step explanation:

Given : If two lines are parallel.

To find : which statement must be true.

Solution : We have given that If two lines are parallel.

We know that two parallel line have same slope

By rise over run :

Therefore, C. Their slopes are equal.
