Answer: 8 spools

Step-by-step explanation:

There are 12 apartments, and each apartment will need 60 meters of cable, so 12×60= 720 meters of cable needed.

If each spool only has 100 meters and he needs 720 meters, then 720÷100= 7.2. So he would need to purchase at least 8 spools, and will have 80 meters left over.

Chad's house is 3/8 units farther away than Kelly's house.

By reading the number line, we can see that:

These fractions are the positions of each location. We want to find how much farther is Chad's house than Kelli's house from the library, this is given by:

(Chad's house position - library position) - (Kelli's house position - library position)

Writting the fractions, we get:

(7/8 - 0) - (4/8 - 0)  = 3/8

So Chad's house is 3/8 units farther away than Kelly's house.

Answer: The first four terms are 33/4, 63/8, 15/2, and 57/8.

Step-by-step explanation: To make it easier, turn 8 1/4 into an improper fraction: 33/4. 33/4=66/8. Because the denominator is the same, it’s easier to subtract.

66/8 - 3/8 = 63/8

63/8 - 3/8 = 60/8

60/8 - 3/8 = 57/8

The first 4 terms in the sequence are 66/8, 63/8, 60/8, and 57/8. But we’re not done b/c we need to simplify. That means the first four terms are 33/4, 63/8, 15/2, and 57/8.

Answer:

They can stay 16 days.

Step-by-step explanation:

3500 - 987 = 2,513

2,513 divided by 150 = 16.7

*They can't stay 16.7 days, so you have to round down. Rounding up will go out of their budget.*

Checking answer:

16 x 150 = 2,400

2,400 + 987 = $3,387

- I'm sure this isn't how your teacher wants you to solve it but this is just how I solved it, I hope this helps!

Step-by-step explanation:

Equation: 987 + 150x = 3500

x represents the number of days the family is staying at the park.

Solve.

Subtract 987 from both sides:

[tex]150x = 2513[/tex]

Divide each side by 150:

[tex]x= 16.75[/tex]

16.75 is decreased to 16, it's impossible to stay for 16.75 days.

The family can stay in the park for 16 days.

Answer:

45cm^2

Step-by-step explanation:

we have two shapes in the diagram a square and a triangle so we find the area of each of them and add them together

finding the area of a square

we have area= s×s

area = 7×5

area = 35cm^2

finding the area of a triangle

1/2 ×b×h

1/2×4×5

area = 10cm^2

so we add together

total area = 35+ 10

area = 45cm^2

Answer: I think it’s 647.96

Linear functions are functions that change at a constant rate

The linear function that models the data is [tex]P(x) = 0.025x -49.695[/tex]

From the question, we have the following ordered pairs

(x,P(x)) = (2005,43%) and (2011,58%)

Start by calculating the slope (m)

[tex]m = \frac{P(x2) - P(x1)}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{58\% - 43\%}{2011 - 2005}[/tex]

Evaluate the differences

[tex]m = \frac{15\%}{6}[/tex]

Evaluate the quotient

[tex]m = 2.5\%[/tex]

The linear function is then calculated as:

[tex]P(x) = m(x - x_1)+ P(x_1)[/tex]

So, we have:

[tex]P(x) = 2.5\%(x - 2005) + 43\%[/tex]

Rewrite as:

[tex]P(x) = 0.025(x - 2005) + 0.43[/tex]

This gives

[tex]P(x) = 0.025x -50.125 + 0.43[/tex]

[tex]P(x) = 0.025x -49.695[/tex]

Hence, the linear function that models the data is [tex]P(x) = 0.025x -49.695[/tex]

Answer:

9, 30, 27

Step-by-step explanation:

To find the perimeter, you must add up each side. In this scenario, we know that the perimeter is 66 feet. We also know the sides, which are n, 3n+3 and 4n-9.

So, we must add the sides to get 66 feet.

n+3n+3+4n-9=66

Combine like terms, and solve:

(n+3n+4n)+(3+-9)=66

8n+-6=66

8n-6=66

n=9

So if n=9, we can easily find the value of the other sides.

3(9)+3=30 feet.

4(9)-9=27 feet

So, the sides are 9, 30, and 27 feet (in order).

Little triangle first - hypotenuse is 4, now we used this info help us find the opposite.

Opposite & Hypotenuse - Sin

Sin(45) = O/H

Sin(45) = O/4

x 4 both sides, to get Opposite

Opposite = 4 x Sin(45)

= 2 root 2

= 2.8284.......

Big Triangle next,

Opposite is 2.8284......

Y is the adjacent

Opposite & Adjacent - Tan

Tan (30) = O/A

Tan(30) = 2.8/A

x A

A x Tan(30) = 2.8

÷Tan(30)

A = 2.8 ÷ Tan(30)

A= 2 root 6

A= 4.8989...

So, y is 5 to 1 significant figure

Or

Y = 4.9 to 1d.p

Given :-

To Find :-

Solution :-

Here the area of the rectangle is 357cm² . As we know that the area of rectangle is ,

→ Area = length * breadth

On substituting the respective values ,

→ 357 cm² = 17cm * length

→ length = 357cm²/17cm

→ length = 21cm

Hence the length of the rectangle is 21cm.
