the length of a rectangular room is 16 less than four times the width. the perimeter of the room is 68 feet. find the length and

Olegator [25]

Answer:

Length = 30.4 ft

Width = 3.6 ft

Step-by-step explanation:

Width: x

Length: 4x + 16

2(x) + 2 (4x + 16) = 68

2x + 8x + 32= 68

10x = 68 - 32

x = 36/10

x = 3.6

Width = 3.6 ft

Length: 30.4 ft

A company has a manufacturing plant that is producing quality jackets. They find that in order to produce 150 jackets in a month

Masja [62]

Answer:

$y = 14x + 3400$

Step-by-step explanation:

Represent

- number of jackets with x

- costs of jackets with y

So, we have:

$(x_1,y_1) = (150,5500)$

$(x_2,y_2) = (370,8580)$

Required

Write an equation in form of y = mx + b

First, we need to determine the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{8580 - 5500}{370 - 150}$

$m = \frac{3080}{220}$

$m = 14\\$

The equation is calculated using:

$y-y_1 = m(x - x_1)$

Where

$m = 14\\$

$(x_1,y_1) = (150,5500)$

So, we have:

$y - 5500 = 14(x - 150)$

$y - 5500 = 14x - 2100$

Make y the subject

$y = 14x - 2100 + 5500$

$y = 14x + 3400$

Which of the following represents the reflexive property of length? Question 6 options: A) m∠A = m∠A B) If AB = CD, then CD = AB

poizon [28]

Answer:

D) AB = AB

Step-by-step explanation:

The reflexive property states that a value is equal to itself: x = x.

The reflexive property of length states that a length is equal to itself:

AB = AB

A) and C) are wrong. They represent the reflexive property of angles.

B) is wrong. It represents the symmetric property of length.

Carrie has 3 times as many green beads as red beads and 2 as many blue beads as green beads if she has 150 total how many green

Vikentia [17]

There are 45 green beads

Solution:

Let the number of red beads be "x"

Given that, Carrie has 3 times as many green beads as red beads

Number of green beads = 3 times number of red beads

Number of green beads = 3x

She 2 as many blue beads as green beads

Number of blue beads = 2 times the number of green beads

Number of blue beads = 2(3x) = 6x

She has 150 total

Therefore,

Number of red beads + Number of green beads + Number of blue beads = 150

x + 3x + 6x = 150

10x = 150

x = 15

Thus, number of green beads = 3x = 3(15) = 45

Thus there are 45 green beads
