a rectangle has a length 8 cm the rectangle has area 20cm^2 the length of the rectangle is increased by 2 cm the area of the rectangle is increased by 4 cm^2 noh says the width of the rectangle decreased less than 5% is noah correct

Answers

9514 1404 393

Answer:

  yes

Step-by-step explanation:

The width of the rectangle is given by ...

  W = A/L

  W = (20 cm²)/(8 cm) = 2.5 cm

__

The modified rectangle has a length of (8 cm +2 cm) = 10 cm, and an area of (20 cm² +4 cm²) = 24 cm². Its width will be ...

  W = (24 cm²)/(10 cm) = 2.4 cm

The percentage change in size is ...

  ((2.4 cm)/(2.5 cm) -1) × 100% = -4%

The width of the rectangle decreased less than 5%. Noah is correct.

Write an equation in point-slope form of the line that passes through the two given points. Use the first point to write the equation (-1, -5) and (3, 2)

Answers

Answer:

The equation in point-slope form of the line is:

[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]

Step-by-step explanation:

Given the points

(-1, -5) (3, 2)

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:-5\right),\:\left(x_2,\:y_2\right)=\left(3,\:2\right)[/tex]

[tex]m=\frac{2-\left(-5\right)}{3-\left(-1\right)}[/tex]

[tex]m=\frac{7}{4}[/tex]

As the point-slope form is defined as

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope.

substituting the values m=7/4 and the first point (-1, -5)

[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]

Therefore, the equation in point-slope form of the line is:

[tex]y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)[/tex]

Answers

Answer: 2521.91 ft^3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Using the cylinder volume formula, V = (pi)r^2h

Since the radius and the height have already been given, no further calculations are necessary.

V= (pi)(6.5)^2(19)

V=(3.14)(42.25)(19)

The rule of thumb in filmmaking is that you must shoot at least 3 minutes of film for every minute in a movies “final cut”. A 30 minute roll of film cost $250. How much will film cost to make a 90 minute movie?

I can't figure out the process of solving it!!!
P.S: It needs to be set up as an inequality
PLS HELPP

Answers

Answer: $750

Step-by-step explanation:

We can solve this using direct proportion.

Let the number of minutes used be x

Let the cost be y

For direct proportion,y = kx

where, y = 250, x = 30

y = kx

250 = 30k

k = 250/30

k = 8.33

The cost to make a 90 minute movie will be:

y = kx

where,

y = unknown

k = 8.33

x = 90

y = 90 × 8.33

y = $750

The cost to make a 90 minute movie is $750.

THIS IS EASY, BUT I- JUST PLEASE HELP ME! NEED NOW!

Answers

To find these out you have to use the strategy of P (parenthesis) E (exponents) M (multiplication) D (division) A (addition) S (subtraction)

3 - 4 x 2 The first thing you need to do is do the multiplication part first, since subtraction is the last thing you need to do. You multiply 4 and 2 and get the answer of 8, then subtract 3 which is 5

5 x 3 - 4 The first thing you need to do is multiplication 5 x 3 which equals 15 and then do 15 - 4 = 11

15 ÷ (3 x 5) x 2 The first thing you do is you do the P (parenthesis) which is (3x5) which equals 15. Then you multiply 15 with 2 which is 30 and then divide 30 with 15 which is 2

5 + 3 x 2 ÷ 6 First you need to do the Multiplication which is 3 x 2 which equals 6, and then you do the division, which is 6 ÷ 6 which is 1. Then add 5 to the 1 which is 6.

2. What does the slope of this model represent?

Answers

Answer:

The y intercept it 0 hours and 44

In this model y intercept represnts the lowest possible score obtainable due to lowest study.

The slope shows there is a direct correlation as x increases so does the value of y so it has a positive slope. All it represents is the more they studied the higher they score
