COMPOSITE FIGURES!!! can you please help

Answers

I believe it would be 470 cm.

For the blue figure, there are two 2 by 2 panels and three 7 by 2 panels that would be exposed to the surface

So (7•2)•3 = 42 and (2•2)•2 = 8 so 42•8=50

The green panel is made up of four 12 by 7 panels and two 7 by 7 panels, with one of them being covered with a 14 cm part.

So (7•12)•4 = 336 and 7•7 = 49. The top part would be 49-14=35 so 336 + 49 + 35 = 420

And 420 + 50 = 470

find 5 rational number between 2/-7 and 5/6

Answers

Answer:

-11/42, -10/42, 10/42, 11/42, 12/42

Step-by-step explanation:

First of let's find the LCM of the denominators.

LCM of 6 and 7 is 42

Thus, -2/7 can also be expressed in terms of 42 as denominator as; -12/42

Similarly, 5/6 can also be expressed in terms of 42 as denominator as; 35/42

Thus, any five rational numbers could come in the form of the numerator being between -12 to 35 with the denominator being 42.

Thus, five rational numbers between -2/7 and 5/6 are;

-11/42, -10/42, 10/42, 11/42, 12/42

A swimming pool is in the shape of a rectangular prism with a horizontal cross-section 10 feet by 20 feet. The pool is 5 feet deep and filled to
capacity. Water has a density of approximately 60 pounds per cubic foot, or 8 pounds per gallon.
What is the approximate weight of water in the pool?

Answers

Answer:

The weight of the water in the pool is approximately 60,000 lb·f

Step-by-step explanation:

The details of the swimming pool are;

The dimensions of the rectangular cross-section of the swimming pool = 10 feet × 20 feet

The depth of the pool = 5 feet

The density of the water in the pool = 60 pounds per cubic foot

From the question, we have;

The weight of the water in Pound force = W = The volume of water in the pool given in ft.³ × The density of water in the pool given in lb/ft.³ × Acceleration due to gravity, g

The volume of water in the pool = Cross-sectional area × Depth

∴ The volume of water in the pool = 10 ft. × 20 ft. × 5 ft. = 1,000 ft.³

Acceleration due to gravity, g ≈ 32.09 ft./s²

∴ W = 1,000 ft.³ × 60 lb/ft.³ × 32.09 ft./s² = 266,196.089 N

266,196.089 N ≈ 60,000 lb·f

The weight of the water in the pool ≈ 60,000 lb·f

The probability of A will be P(A) = 1/2. The probability of B will be P(B) = 1/2. The probability of A and B will be P(A and B) = 1/4

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

Event A: Rolling a number less than 4 on a number cube.

Event B: Flipping heads on a coin toss

We need to find the probability of A, the probability of B, and the probability of both A and B.

The probability of A will be

P(A) = 1/2

The probability of B will be

P(B) = 1/2

The probability of A and B will be

P(A and B) = 1/2 x 1/2

P(A and B) = 1/4

Given the vertex of a parabola is (-3,1) and also contains the point (-4,-1). State the exact equation of the parabola in vertex form, show all your work.

Answers

Answer:

y = -2(x + 3)^2 - 1

Step-by-step explanation:

The vertex equation of a parabola is y = a(x - h)^2 + k. If the vertex here is (-3, 1), then this equation becomes y = a(x + 3)^2 + 1.

Knowing that the graph passes through (-4, -1), we let y = -1 and x = -4, obtaining:

-1 = a(-4 + 3)^2 - 1, which must be solved for a:

-1 = a - 1. Therefore, a = -2, and the exact equation of this parabola is:

y = -2(x + 3)^2 - 1

George bought a model of a Viking ship for $68. If he paid
$5.10 in sales tax, what was the sales tax rate?

Answers

Answer:

We can convert 6.75% to a decimal by dividing by 100.

If x is the price of the house, then the sales tax is 0.0675x. The price of the house and the sales tax add up to $319,000.

x+0.0675x=319,000

Combe terms on the left.

1.0675x=319,000

Finally, divide both sides by 1.0675.

x=319,0001.0675=298,829.04
