Answer 1

Answer:

About 6 hours.

Step-by-step explanation:

The cylinder has a diameter of 10 meters and a depth of 1.4 meters.

First, we can find the volume of the cylinder, given by the formula:

[tex]V=\pi r^2h[/tex]

Where r is the radius and h is the height (or depth, in this case).

Since our diameter is 10, our radius is 5.

Therefore, the volume of the cylinder will be (using 3.14 as π):

[tex]V=(3.14)(5)^2(1.4)=109.9\text{ meters} ^3[/tex]

Since water is pumped at a rate of 18 cubic meters per hour, it will take then:

[tex]109.9/18=6.10\overline{5}\approx 6\text{ hours}[/tex]

So, it will take about 6 hours for the water to completely fill the pool.

A candy store sells 7 packs of bubble gum for $29.33. How much would it cost to buy 3 packs?

Answers

Hi there,

Recall how 7 packs for gum sell for $29.33.

Before we can calculate how much it would cost to sell 3 packs of gum, we must calculate how much it would first cost to sell 1 pack of gum.

The cost of 1 pack of gum is the current total cost divided by the total amount of gum packs you receive at that price.

In this case, the total cost is $29.33, and we receive 7 gum packs at that price.

Therefore, the cost of 1 pack of gum is [tex]\frac{29.33}{7}[/tex], which equates to $4.19.

We now know that each pack of gum costs $4.19.

Hence, 3 packs of gum would cost three times that price.

[tex]4.19 * 3 = 12.57[/tex]

The cost of 3 packs of gum is $12.57.

Hope that helps!

Stephen purchased a guitar, which was originally priced at $80 but
discounted at 25%. He also had to pay 5% sales tax. What amount did
Stephen pay to purchase the guitar? *

Answers

$24

(ignore this i don’t have enough characters )

Answer:

57 dollars

Step-by-step explanation:

1. Solving the 25% discount

25% = .25

80 x .25 = $20

80 - 20 = $60

** We subtracted 80 from 20 because 25% of 80 is 20 BUT We're taking 25% OFF of 80 because it was a discount.

2. Solving the 5% Tax

5% = .05

$60 x .05 = 3

$60 + 3 = $63

**Adding tax to the discounted price

Mr. Trainer is building a bookcase. He has two wooden boards that are each 8 feet long. He needs to cut the wooden boards into pieces that are 16 inches long. What is the greatest number of 16-inch pieces that Mr. Trainer can cut from the two wooden boards? (1 foot = 12 inches)

Answers

Answer:

12

Step-by-step explanation:

Length of one of the boards = 8 feet

Converting to inches

[tex]1\ \text{foot}=12\ \text{inches}\\\Rightarrow 8\ \text{feet}=8\times 12=96\ \text{inches}[/tex]

One cut is 16 inches

So, we divide the length of the board by 16

[tex]\dfrac{96}{16}=6[/tex]

So, one board is cut into 6 pieces.

The other board is also 8 feet long.

So, the number of pieces the other board is cut into is also 6.

Hence, a total of [tex]6+6=12[/tex] pieces of each 16 inches long can be cut from the two boards.

What is the quotient of 2.592\times 10^72.592×10 7 and 7.2 \times 10^47.2×10 4 expressed in scientific notation?

Answers

The quotient, expressed in scientific notation, is:

Quotient = 0.36 × 10³

Given:

(2.592 × 10⁷) / (7.2 × 10⁴)

To find the quotient of 2.592 × 10⁷ and 7.2 × 10⁴ and express it in scientific notation, we divide the coefficients and subtract the exponents.

Quotient = (2.592 × 10⁷) / (7.2 × 10⁴)

Dividing the coefficients, we get:

Quotient = 2.592 / 7.2 = 0.36

Subtracting the exponents, we get:

10⁷ - 10⁴ = 10⁽⁷⁻³⁾ = 10³

In scientific notation, the coefficient should be between 1 and 10, so we can rewrite the expression as:

Quotient = 0.36 × 10³
