16. Find The Value Of Y.

Answers

Answer 1

y + (2x -12) = 180 (since they are supplementary angles)

(2x-12) = 96 ( since they are alternate exterior angle)

2x = 96 + 12

2x = 108

x = 108/2

x = 54.

y+( 2x-12)=180

y+(2× 54 -12) = 180

y + (108-12) = 180

y + 96 = 180

y= 180-96

y = 84.

Jeremy lost his dog, and wants to make some signs to put up in the neighborhood. The cost to make 8 paper signs and 2 laminated signs is $12.00. The cost to make 10 paper signs and 10 laminated signs is $30.00. What is the cost of 1 laminated sign?

Answers

Answer:

cost to make paper signs = $1

cost to make laminated signs = $2

Step-by-step explanation:

Let

x = cost to make paper signs

y = cost to make laminated signs

8x + 2y = 12 (1)

10x + 10y = 30 (2)

Multiply (1) by 5

40x + 10y = 60 (3)

10x + 10y = 30 (2)

Subtract (2) from (3) to solve for x

40x - 10x = 60 - 30

30x = 30

x = 30/30

x = $1

Substitute x = 1 into (1)

8x + 2y = 12

8(1) + 2y = 12

8 + 2y = 12

2y = 12 - 8

2y = 4

y = 4/2

y = $2

cost to make paper signs = $1

cost to make laminated signs = $2

Sasha grew 36 plants with 9 seed packets. How many total seed packets does Sasha
need if she wants to have 76 plants in her backyard in all? Solve using unit rates.
seed packets

Answers

Answer:

10 more seed packets.

Step-by-step explanation:

36/9=4 so there are 4 seeds in each packet. If she already has 36 plants, she only need 40 more to get the 76 she wants. 40/4=10 so she needs 10 more seed packets.

Which of the following is a transformation of the graph y = (x - 5)^2?

A.Shifts down 5.

B.Shifts right 5.

C.Shifts left 5.

D.Shifts up 5.​

Answers

Answer: B. Shifts right 5


Explanation:

When the number after the variable is in the parentheses, the transformation will be opposite of the sign. In this problem, the sign for 5 is negative so you would be going right 5 units because right is positive so that would be the opposite of the sign.

1. Kristen spent $131 on shirts at Target last week. She bought some fancy shirts for
$28 each and then some plain t-shirts for $15 each. If she bought a total of 7 shirts,
then how many of each type of shirt did she buy?
problem #1
problem #2

Answers

Answer:

Kristen bought 2 fancy shirts and 5 plain t-shirts.

Step-by-step explanation:

Given that,

Kristen spent $131 on 7 shirts.

Cost of one fancy shirt = $28

Cost of one plain t-shirt = $15

Let,

x be the number of fancy shirts

y be the number of plain t-shirts

x+y = 7       Eqn 1

28x+15y=131    Eqn 2

Multiplying Eqn 1 by 15

15(x+y=7)

15x+15y=105    Eqn 3

Subtracting Eqn 3 from Eqn 2

(28x+15y)-(15x+15y)=131-105

28x+15y-15x+15y=26

13x=26

Dividing both sides by 13

[tex]\frac{13x}{13}=\frac{26}{13}\\x=2[/tex]

Putting x=2 in Eqn 1

2+y=7

y=7-2

y=5

Hence,

Kristen bought 2 fancy shirts and 5 plain t-shirts.

The side length of an equilateral triangle is 6x - 12. Write an expression for the perimeter of the triangle in simplest form.

Answers

Answer:

18x - 36

Step-by-step explanation:

In an equilateral triangle the 3 sides are congruent, then

perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms

                = 18x - 36

The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

What is the perimeter of a triangle?

The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

As we know in an equilateral triangle the 3 sides are congruent.

The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12

Combine the likewise terms and we get

The perimeter of the triangle =  18x - 36

Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

After a robot vacuum is fully charged, it can run for 15 minutes. It can vacuum 1/2 square foot every second. Can a fully charged robot clean a room that is 400 square feet without recharging?

Answers

Answer:

The robot can clean the room without recharging.

Step-by-step explanation:

Given:

After a robot vacuum is fully charged, it can run for [tex]15[/tex] minutes.

The robot cleans [tex]\frac{1}{2}[/tex] square foot every second.

To find: If the charged robot can clean a room that is [tex]400[/tex] square feet without recharging.

Solution:

Area cleaned by the robot in [tex]1[/tex] second [tex]=\frac{1}{2}[/tex] square foot.

We know that, [tex]1[/tex] minute [tex]=60[/tex] seconds.

So, [tex]15[/tex] minutes [tex]=15\times 60=900[/tex] seconds.

Now, area cleaned by the robot in [tex]900[/tex] seconds [tex]=\frac{1}{2} \times 900=450[/tex] square feet.

The area to be cleaned is [tex]400[/tex] square feet.

Hence, the robot can clean the room without recharging.

5 less than a number x is 3 times the sum of a number x and 2? (i need a word problem not the answer)

Answers

Answer:

Yesterday I squeezed 2 kilos of apples in a barrel.

Today I have picked 5 extra kilos of apples and save them in a basket.

By the end of the day, I want to squeeze some of them and add to the barrel.

Apple juice from the barrel is valued 3 times the same amount of raw apples.

I want to find how many apples I can squeeze today (x) such that the value of the remaining raw apples is equivalent to the total value of produced apple juice.

Step-by-step explanation:

The equation is 5-x = 3 * (x + 2).

If x is the amount of apple to squeeze (in kilos) then 5-x is the remaining raw apples and x+2 is the total quantity of juice.

Since that juice is valued 3 times the raw apples we obtain the equivalence defined in the equation above.
