Triangle ABC is similar to triangle DEF. What is the value of x ?
Answer:
A
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AC}{DF}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values
[tex]\frac{45}{x+8}[/tex] = [tex]\frac{30}{25}[/tex] ( cross- multiply )
30(x + 8) = 1125 ( divide both sides by 30 )
x + 8 = 37.5 ( subtract 8 from both sides )
x = 29.5 → A

Answer:
1.) The 1ˢᵗ three term is (-32), (-7) and 18
2.) The 1ˢᵗ three term is 127, 106 and 85
Step-by-step explanation:
1.)Here,
First Term = a₁ = - 32
Common Difference = (d) = 25
Now, For 1ˢᵗ three term,
n = 1
a₁ = - 32
n = 2
aₙ = a + (n - 1)d
a₂ = (-32) + (2 - 1) × 25
a₂ = (-32) + 1 × 25
a₂ = (-32) + 25
a₂ = -7
n = 3
aₙ = a + (n - 1)d
a₃ = (-32) + (3 - 1) × 25
a₃ = (-32) + 2 × 25
a₃ = (-32) + 50
a₃ = 18
Thus, The 1ˢᵗ three term is (-32), (-7) and 18
2.)Here,
First Term = a₁ = 127
Common Difference = (d) = -21
Now, For 1ˢᵗ three term,
n = 1
a₁ = 127
n = 2
aₙ = a + (n - 1)d
a₂ = 127 + (2 - 1) × (-21)
a₂ = 127 + 1 × (-21)
a₂ = 127 - 21
a₂ = 106
n = 3
aₙ = a + (n - 1)d
a₃ = 127 + (3 - 1) × (-21)
a₃ = 127 + 2 × (-21)
a₃ = 127 - 42
a₃ = 85
Thus, The 1ˢᵗ three term is 127, 106 and 85

A local high adventure park has a zip line that begins 46 feet in the air. The angle of elevation of the cable is 35º. Estimate the length of
the zip line cable. Round your answer to the nearest hundredth if necessary.
Answer: [tex]80.2\ ft[/tex]
Step-by-step explanation:
Given
Zipline begins [tex]h=46\ ft[/tex] in the air
The angle of elevation is [tex]35^{\circ}[/tex]
Assume the length of the cable is l
from the figure, we can write
[tex]\Rightarrow \sin 35^{\circ}=\dfrac{46}{l}\\\\\Rightarrow l=\dfrac{46}{\sin 35^{\circ}}\\\\\Rightarrow l=80.19\approx 80.2\ ft[/tex]

Two stores each have the same number of lawn mowers for sale. The lawn mowers at Store A have a median price of $150. The lawn mowers at Store B have a median price of $200.
What can best be inferred from this data?
A. Store A has more expensive lawn mowers.
B. Store B has more expensive lawn mowers.
C. The stores have the same amount of expensive lawn mowers.
D. It is impossible to say which store has more expensive lawn mowers.
Answer:
Store B has more expensive lawn mowers.
Step-by-step explanation:
The median price is the price in the middle of the possible prices which means that if you double the median price you will get about what the highest price can be.
What can be inferred from the data is store B has more expensive lawn mowers.
What does median mean?Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order. Median is a measure of central tendency. For example 3 is the median in this dataset: 1, 3, 6

An extra-large pizza weighs 2 kilograms. How many grams does it weigh?
Sales Tax: At the movie theater, a bucket of popcorn costs $8.00 and a soda costs $2.50. How much will you pay in sales tax if the rate is 6%?
We have to pay $0.63 sales tax if the rate is 6%.
What is the sales tax?
Sales tax is a tax that is added to the price of goods or services when they are sold. It is typically a percentage of the purchase price and is collected by the seller from the buyer.
In this case, the price of the bucket of popcorn is $8.00 and the price of the soda is $2.50. If the sales tax rate is 6%, the total amount of sales tax paid on the popcorn would be $8.00 x 6/100 = $0.48 and on soda is $2.50 x 6/100 = $0.15. So the total amount of sales tax paid on both items is $0.48 + $0.15 = $0.63
Hence, we have to pay $0.63 sales tax if the rate is 6%.

Step-by-step explanation:
1. isosceles triangle
2. 3x + 15 = 90 x = 25
x + 25 = 90 x = 65
x + 55 = 90 x = 35
3. The size for DAB is 84
My reasoning is I went from one angle to another by subtracting 180 from my answers. For example angle 132 is supplementary to the missing angle next to it. I subtract 180 from 132 and get 48. That already solves the 2 equivalent angles in the triangle so I have 48+48+x = 180 because a full triangle equals 180. I get x = 84 then I do the same thing I did with angle 132. Angle 84 is supplementary to the missing angle next to it. I subtract 84 from 180 and get 96 then go diagonal from angle C (which is 96) to angle A. Those are supplementary so I subtract 96 from 180 and get 84.
Which of the following relations is a function?
a
{(1, 1), (1, 2), (1, 3)}
b
{(0, 0), (0, 1), (1, 2)}
c
{(2,0), (3, 2), (5, 2)}
d
{(3, 1), (4, 1), (3, 2)}
Answer:
C is a function
Step-by-step explanation:
For every input in a relation, there should only exist one unique output. For example, in option A, the input 1 has 3 outputs which does not make it a function since they all have to be unique. Additionally, B and D aren't functions for the same reasons. Therefore, C is a function.
