The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?
OA
12 inches
OB. 15 inches
OC 21 inches
OD. 40 inches

Answers

Answer 1

Answer:

Option B: 15 inches

Step-by-step explanation:

p=2w+2l so 12 (2*6) +2x= 42

42-12=30

30/2=15

Answer 2
The answer is:

15 inches

Explanation:

P = perimeter = 42

L = length = ?

W = width = 6

P rectangle = 2L + 2 W

Substitute into formula:

42 = 2L + 2 * 6

42 = 2L + 12

42 - 12 = 2L

30 = 2L

L = 30/2 = 15

L = 15 inches

I hope this helps!!!

Matter is in a liquid state when its temperature is between its melting point and its boiling point. Suppose that some substance has a melting point of negative 35.84 degrees Upper C and a boiling point of 310.69 degrees Upper C . What is the range of temperatures in degrees Fahrenheit for which this substance is not in a liquid​ state? (Hint: Upper C equals five ninths left parenthesis Upper F minus 32 right parenthesis ​) Express the range as an inequality. Let x represent the temperature in degrees Fahrenheit. What is the range of temperatures for which this substance is not in a liquid​ state? nothing ​(Type an inequality or a compound inequality. Simplify your answer. Use integers or decimals for any numbers in the expression. Round to three decimal places as​ needed.)

Answers

Answer:

96.512 °F < x < 591.242 °F

Step-by-step explanation:

We are given;

Melting point = 35.84 °C

Boiling point = 310.69 °C

Now, we are given that formula to convert °C to °F is;

°C = (5/9)°F

Thus if the temperature in Fahrenheit is x, then;

Melting point is; 35.84 °C = (5/9)x°F - "32"

x = ((9 × 35.84)/5) + 32

x = 96.512 °F

Similarly, for Boiling point;

Boiling point is;

310.69 °C = (5/9)x°F - "32"

x = ((9 × 310.69)/5) + 32

x = 591.242 °F

Now, we are told that matter is in its liquid form when it is between melting and boiling point.

Thus, range of x in inequality form is;

96.512 °F < x < 591.242 °F

Caleb paid $4.50 for 12 bagels. Which of the following have a unit price for bagels that is greater than the unit price Caleb pald? Select all that
apply
A) $2.25 for 6 bagols
B) $13.50 for 10 bagels
c) $3.30 for 6 bagols
D) $5.00 for 12 bagets
E) $8.10 for 18 bagels

Answers

B, C, D, and E because all their unit prices are higher then what Caleb paid. You find the unit price by dividing the money by the amount of bagels.

Options B, C, D, and E have a unit price for bagels that is greater than the unit price Caleb pald because all their unit prices are higher then what Caleb paid.

How to calculate unit price of something?

Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.

unit price of something is price of 1 thing.

LEts suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.

Given that Caleb paid $4.50 for 12 bagels.

Unit price = 4.50 / 12 = 0.375

A) $2.25 for 6 bagols

Unit price = 2.25 / 6 = 0.375

B) $13.50 for 10 bagels

Unit price = 13.50 / 10= 1.35

c) $3.30 for 6 bagols

Unit price = 3.30 / 6 = 0.55

D) $5.00 for 12 bagets

Unit price = 5.00 / 12 = 0.41

E) $8.10 for 18 bagels

Unit price = 8.10 / 18 = 0.45

Hence, Options B, C, D, and E have a unit price for bagels that is greater than the unit price Caleb pald because all their unit prices are higher then what Caleb paid.

Answer:

The answer is D: 42

Step-by-step explanation:

Angle 7 and angle 138 are supplementary and must add up to 180

Angle 7 is congruent to angle 6 through CPCTC (Corresponding Parts of Congruent Triangles are Congruent)

Angle 7 and 6 are corresponding angles

you must find angle 7 becasue Angle 7= Angle 6

angle 7=x

138-x=180

solve for equation you get

Two angles are complementary. One angle is twice the size of the other. The bigger angle measures

Answers

Sum of two angles that are complementary = 90°

Let the smaller angle be x .

Then the larger angle = 2x

Let us make an equation to find the measure of both the angles :-

[tex]2x + x = 90[/tex]

[tex]3x = 90[/tex]

[tex]x = \frac{90}{3} [/tex]

[tex]x = 30[/tex]

Which means :-

Measure of the small angle = 30°

Measure of the larger angle = 2 × 30 = 60°

Therefore , the measure of the bigger angle is 60° .

so then since it is overlap we multiply by two 12 cm*2= 24 cm

Then we add 135 and 83= 135+83 = 218 cm

218 cm - 24 cm = 194 cm
