Can someone help me and let me know if my answer is correct?A large emerald with a mass of 764.3 grams was recently discovered in a mine. If the density of the emerald is 2.76grams over centimeters cubed, what is the volume? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.

276.92

Answers

Answer 1

Answer: The answer is 276.92

The density (D) of is quotient of mass (m) and volume (V):
$D = (m)/(V)$

It is given:
m = 764.3 g
D = 2.76 g/cm³
V = ?

Since:
$D = (m)/(V)$
⇒ $V= (m)/(D)= (764.3g)/(2.76g/cm^(3) ) = 276.92 cm ^(3)$

Therefore, the volume of the emerald is 276.92 cm² and your answer is correct.

Answer 2

Answer:

Answer:

276.92 cubic cm.

Step-by-step explanation:

Given :

A large emerald with a mass of 764.3 grams was recently discovered in a mine.

The density of the emerald is $2.76gm/cm^3$

To Find: what is the volume?

Solution:

Density = $2.76gm/cm^3$

Mass = 764.3 grams

$Volume=(Mass)/(Density)$

$Volume=(764.3)/(2.76)$

$Volume=276.92$

Hence the volume of large emerald is 276.92 cubic cm.

Sally is making masks for her family. Her pattern calls for a rectangle that is 9 x 14. If one yard of fabric is 36 x 42 (after the salvage edge is removed), how many masks can she make from one yard of fabric? If her fabric was on sale for $3.00 per yard, what is the fabric cost of one mask? If her fabric is regularly priced at $9.00 per yard, what is the fabric cost of one mask? Answer: Number of masks: Cost using discount fabric: $ Cost using regular priced fabric:

Answers

Answer:

how many masks can she make from one yard of fabric?

the maximum she can obtain is 4 (9 x 4 = 36) x 3 (14 x 3 = 42) = 12 masks from one yard of fabric.

If her fabric was on sale for $3.00 per yard, what is the fabric cost of one mask?

the fabric cost of 1 mask at a discount price = $3 / 12 = $0.25 per mask

If her fabric is regularly priced at $9.00 per yard, what is the fabric cost of one mask?

the fabric cost of 1 mask at regular price = $9 / 12 = $0.75 per mask

A circular patio has a radius of 18 feet.What is the longest distance across the patio?
A.
9 ft
B.
18 ft
C.
36 ft
D.
54 ft

Answers

The longest distance of a circle is its circumference.

Circumference = π d
d = diameter is twice the radius

C = 3.14 * 2 * 18ft
C = 3.14 * 36 ft
C = 113.04 ft

However, with the choices we only need to get the diameter as the longest distance from one end of the circular patio to the other.

d = 2 r
d = 2 * 18ft
d = 36 ft. CHOICE C.

We have some clues here.

'longest distance' could mean Diameter.

r*2= d
radius = 18 feet
18*2 = 36

d = 36

The answer would be: 36 ft

Jake needs 9 pieces of rope that are each the same length. He cuts the pieces from a rope that is 8 yards long and uses up the whole piece of rope.How long is each piece of rope?
WRITE THE ANSWER AS A FRACTION AND DECIMAL.

Answers

9 pieces of rope form an 8 yard long rope

Divide.

8/9 yards of rope.

8/9 is approximately 0.89.

So 8/9 yards of rope or 0.89 yards of rope.

ANSWERS
Each rope has a length of 8/9 yards, or $0.\overline{8}$ yards (repeating digit is 8).

EXPLANATION
Division can be used to solve this problem.

In general, the equation "a/b = c" models the following situation: If you have something that is a units long and you divide it into b equal parts, then each equal part will be c units long.

We have a rope that is 8 yards long and we need 9 equal pieces.
Divide 8 yards by 9 to get the length of each piece.

$\begin{aligned}{}^\text{length of}_\text{each piece}&= \frac{8\text{ yard}}{\text{9 piece} } \n&= 8/9 \text{ yards per piece} \n&= 0.\overline{8} \text{ yards per piece}\end{aligned}$

Each piece is 8/9th of a yard or $0.\overline{8}$ yards long.

We can confirm this by adding the lengths of the nine equal pieces of rope back up to get the original length of the rope:

$\begin{aligned}\underbrace{(8)/(9) + (8)/(9) + (8)/(9) +(8)/(9) +(8)/(9) +(8)/(9) +(8)/(9) +(8)/(9) +(8)/(9)}_{\text{9 pieces, each of them 8/9th of a yard long}} &= 9 \cdot \left((8)/(9) \right) \n&= 8\end{aligned}$

An automobile factory is assembling cars and they need to have all of the parts in stock at the assembly line. Each car needs four tires and a spare tire for the trunk. If they produce c cars per day, what formula shows how to calculate the number of tires, t, needed?

Answers

t = 5c

Each car needs 5 tires (4 on it and 1 spare, which add up to five). So for every one car they make they need 5 tires. Two cars would need 10 tires, 3 would need 15 tires, etc, so the number of tires can be found by multiplying the number of cars by 5. Putting this into equation form, you'd get t = 5c

Final answer:

The formula to calculate the number of tires needed in an automobile factory is t = (4c) + c, where t represents the number of tires needed and c represents the number of cars produced per day.

Explanation:

The formula to calculate the number of tires needed in an automobile factory is given by:

t = (4c) + c

Where t represents the number of tires needed and c represents the number of cars produced per day.

For example, if the factory produces 100 cars per day, we can substitute c = 100 into the formula to find that t = (4 * 100) + 100 = 500 + 100 = 600. Therefore, the factory would need 600 tires per day.
