- If the exterior angle of the triangle measure 133°, and its remote interior
angles measure x° and (2x-5)°, what is the value of x?
a. x = 61.7°
b. x = 133°
c. x = 47°
d. x = 46°
Answers
Answer:
D
Step-by-step explanation:
Mathematically;
the exterior angle is the sum of the two remote interior angles
Thus;
x + 2x-5 = 133
3x-5 = 133
3x = 133 + 5
3x = 138
x = 138/3
x = 46

What is the image of (-3, -3) after a dilation by a scale factor of 1/3 centered at the
origin?
Answers
The image of (-3, -3) after dilation by a scale factor of 1/3 centered at the origin is (-1, -1).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
Given, the image of (-3, -3) after dilation by a scale factor of 1/3 centered at the origin will be,
= (-3/3, -3/3).
= (-1, -1).
It has been shrinked by a factor of three the image became smaller.

A swimming pool is 30 feet wide and 50 feet long. If it is surrounded by square tiles, each of which is 1 foot by 1 foot, how many tiles are there surrounding the pool?
Answers
Answer:
164 tiles
Step-by-step explanation:
Per the above details, we will require tiles along all the sides of the swimming pool ,hence the circumference of the pool is denoted as;
= 2(wide + long)
Wide = 30 feet
Long = 50 feet
Circumference = 2(30 + 50)
Circumference = 2(80)
Circumference = 160.
It means that minimum of 160 tiles of 1 ft length is required, however, we will also require tile on each of the corners(4), total equals
= 160 + 4
= 164 tiles
A total of 164 tiles are there surrounding the pool.
Carrie wants to conduct a randomized experiment on 50 articles of her dirty clothing to see if detergent A or detergent B cleans better. Which of the following best describes the method for randomization using slips of paper within this experiment?
A. Label each article of clothing with a number from 1 to 50, and write those numbers on identical slips of paper. Shuffle the slips of paper and choose 25 slips of paper to wash with detergent A and the remaining slips to wash with detergent B.
B. Label each article of clothing with a number from 1 to 50, and write those numbers on identical slips of paper. Shuffle the slips of paper and choose 25 of them.

We need to find the expression into an equivalent.
Therefore, given expression is
2(4x+1)
This expression could also be given by;
2(4x+1) = 2(4x ) + 2
Now, we know that:

Answers
Answer:
C
Step-by-step explanation:
On the left, we have 3 positive x bars and 8 1s.
Hence, the left can be represented by the following expression:
[tex]3x+8[/tex]
On the right, we have 4 positive x bars and 6 1s.
Hence, the right can be represented by the following expression:
[tex]4x+6[/tex]
The two are equivalent. Therefore:
[tex]3x+8=4x+6[/tex]
Solve for x. Subtract 6 from both sides:
[tex]3x+2=4x[/tex]
Subtract 3x from both sides:
[tex]2=x[/tex]

How many moles are in the 500.0g lump of coal (which is made of carbon) that you received in your Christmas stocking last year?
How many carbon atoms are in this 500.0g lump of coal?
Answers
Answer:
Number of moles = 41.67 (Approx)
Number of carbon atom = 250.97 x 10²³ (Approx)
Step-by-step explanation:
Given:
Amount of carbon = 500 g
Find:
Number of moles
Number of carbon atom
Computation:
Number of moles = 500 / Atomic number of weight
Number of moles = 500 / 12
Number of moles = 41.67 (Approx)
Number of carbon atom = Number of moles x Avogadro number
Number of carbon atom = 41.67 x 6.023 x 10²³
Number of carbon atom = 250.97 x 10²³ (Approx)

Carlo and Helen spend the same amount of money on art supplies. Carlo buys 4 glue
sticks and spends $3 on glitter. Helen buys 2 glue sticks, and she spends $3.75 on tape
and $2.75 on paint. What is the cost, x, of each glue stick?
Answers
Since we don't have a total cost we will write an equation that will allow us to find the cost of x. The equation is 4x= 2x + $3 + $3.75 + $2.75. Now that we have our equation we are going to start by adding 3, 3.75, and 2.75. When added together, they come out with a total of 9.5. Now the equation becomes 4x= 2x + $9.50. Since we have our new equation we are going to subtract 2x from both sides of the equation. We now have the equation 2x= $9.50. Finally, you will divide both sides by 2. This leaves us with the final outcome x= $4.75. This means that one glues stick cost $4.75. Let's check by substituting $4.75 as the value of x in the expressions 4x is Carlo's total and 2x + $3 + $3.75 + $2.75 is Helen's total. First we do 4x, 4 multiplied by 4.75 equals 19, so Carlo spent $19 on art supplies. Now we do 2x + $3 + $3.75 + $2.75, which is 9.5 added to 9.5 and equals 19. So Helen spent $19 on art supplies. This proves that the cost of one glue stick, x, is equal $4.75.

y=2x- 1.5
Now if a line is parallel to another line the slope will be the same. If perpendicular the slope will be the negative reciprocal. As you said it is parallel the slope is 2.
y = mx+b
