After taking core samples all over a cone-shaped mountain, you have determined that for every 1,000,000 yd3 there is about 2 lbs of gold to be mined. If the mountain has a base that is 2,000 yards wide and a height that is 3,000 yards tall, about how much gold is it expected to hold?
To find the expected amount of gold in the mountain, calculate the volume of the cone and multiply it by the gold density.
Explanation:To determine the amount of gold expected to be held in the mountain:
Calculate the volume of the cone using the formula V = (1/3)πr²h.
Convert the volume to cubic yards since the gold density is given in lbs per 1,000,000 yd³.
Multiply the volume by the gold density to find the total amount of gold expected in lbs.

please help Use the expression 8a + 16c.
Part A
Factor the expression using the GCF.
A. 2(4a + 8c)
B. 4(2a + 4c)
C. 8(a + 2c)
D. 16(12a + c)
Part B
What is the value of the expression when a = –5 and c = –1? Enter your answer in the box.
The required expression is C. 8(a + 2c) and value of the expression when a = –5 and c = –1 is -56.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given the expression is
8a + 16c.
To find the Factor form of the given expression by using GCF.
We have,
8a + 16c.
Factors of each term:
8a = 2 x 2 x 2 x a
16c = 2 x 2 x 2 x 2 x c
The common factors are 2, 2 and 2. then Taking out the greater common factor (GCF) in the given expression;
GCF = 8
The answer is C. 8(a + 2c)
when a = –5 and c = –1
Then;
8(a + 2c)
8(-5 + 2(-1)) = 8 (-7) = -56

The Running Shoe Company advertised that tbe would award a number of prizes equal to 1% of the total number of entries in a contest .They received 1,600 entries .How many prizes should they award?
The Running Shoe Company should award 16 prizes, as 1% of 1,600 entries is 16.
The student asked, "How many prizes should The Running Shoe Company award if they received 1,600 entries in a contest and they award a number of prizes equal to 1% of the total number of entries?"
To find the number of prizes, we need to calculate 1% of 1,600 entries.
Step 1: Convert the percentage to a decimal by dividing by 100. So, 1% becomes 0.01.
Step 2: Multiply the total number of entries by 0.01 to find 1% of it.
1,600 entries * 0.01 = 16 prizes
Therefore, The Running Shoe Company should award 16 prizes.

Hurry I'm TIMED!!!! The following graph shows the low temperatures for the past six nights. What was the range of temperatures for the six nights?
34°F
22°F

Answer:
the answer above is incorrect! So you take 22 which is the lowest on the graph and you take 34 which is the highest on the graph and 8 is not on the graph so 34-22=12

Use the formula A=bh , where A is the area, b is the base length, and h is the height of the parallelogram, to solve this problem.
Brittany is painting a mural on one of the walls in her room. The mural is in a parallelogram-shaped frame. The area of the mural is 1056 in² and the base is 32 inches.
What is the height of the mural?
Enter your answer in the box.
[___] in
The area of the mural is 1056 in² and the base is 32 inches. We have to determine the height of the mural.
Area of parallelogram = [tex] b \times h [/tex]
where 'b' is the base and 'h' is the height.
1056 [tex] in^{2} [/tex] = 32 [tex] \times h [/tex]
[tex] h=\frac{1056}{32} [/tex] in
Therefore, the height of the mural is 33 inch.

A parallelogram is symmetric with respect to either diagonal. true or false?
Not all parallelogram is symmetric with respect to either diagonal, therefore the answer is False.
A parallelogram is known as a quadrilateral (having four sides) with two pairs of parallel-lateral lines. A parallelogram has no line of symmetry but there are some exceptions to specific types of parallelograms. For example:
Rhombus is a special type of parallelogram and it has two lines of symmetry along its diagonals.A rectangle has two lines of symmetry going through the mid-point of the opposite sides.A square has four lines of symmetry with two lines going through the diagonal and two lines going through the opposite sides.Therefore, we can conclude that not all parallelogram is symmetric with respect to either diagonal.

Find the exact area of the shaded region in terms of pi. (Please show work)
Answer:
shaded area = 24.5π -49
Step-by-step explanation:
The area of a segment of a circle is given by the formula ...
A = 1/2r²(θ -sin(θ))
Here, the radius of the circle is (7 cm)/2 = 3.5 cm, and the angle of interest is π/2 radians.
There are 8 segments of this size in the shaded area, so we have ...
shaded area = 8(1/2)(3.5 cm)²(π/2 -sin(π/2))
shaded area = 24.5π -49

A spinner that has 4 equal parts that are the colors blue, green, red, and yellow. The spinner is spun 12 times. It lands on blue 1 time.
Part A) What is the experimental probability of the spinner landing on blue?
Part B) Compare the experimental and theoretical probabilities of the spinner landing on blue. If the probabilities are not close, explain a possible reason for the discrepancy.
Answer:
The experimental probability would be 1/12 and the theoretical probability would be 1/4. The probabilities were not close so a possible reason for the discrepancy would be the blue color on the spinner was slippery.
Step-by-step explanation:
So to start out you need to find out the experimental probability. If the spinner landed on blue 1 time out of 12 different times, you write that as a fraction of 1/12. So 1/12 is the experimental probability. It also asks for the theoretical probability. There are 4 parts of the spinner so 4 is the denominator, one of those possibilities is the one we want so 1 is the numerator, so the theoretical is 1/4. The probabilities were not close so a possible reason for the discrepancy would be the blue color on the spinner was slippery.
Just to tell you what theoretical and experimental probabilities mean is that the theoretical is the possible outcome before you do it. Experimental is where you judge your probability off of past events.

In order to compute for the number of seats available in the auditorium, you just have to divide the number of people at the concert with the percentage of its utilized capacity.
Solution:
170 people / 85% = 200 seats available in the auditorium
To check the answer:
200 seats x 85% = 170 people are in the concert
