Justine just ran her first race. Her distance from the finish line decreased as she ran.
This situation can be modeled as a linear relationship.
What does the y-intercept of the line tell you about the situation?
A. justine finished the race in 40 minutes
B. when justine started the race she was 10 kilometers from the finish line
C. after running for 20 minutes justine was 6 kilometers from the finish line
D. justine ran 4 kilometers every 20 minutes
Answers
Choices B and C are both correct statements.
Choices A and D are both false.
The y-intercept of the line tells us about the situation when Justine started the race she was 10 kilometers from the finish line.
What are y-intercept and x-intercept?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
Given, a line whose y-intercept is at y = 10 which is represented by the distance remaining in kilometers. Since x shows the time spent running that means at x = 0 she started running.
Therefore, The y-intercept of the line reveals that Justine was 10 kilometers from the finish line when she started the race.

The length of three sides of a triangle are 3x+1/2 ,2x+1/4 , and x +1/2 .the perimeter of the triangle is
Answers
Answer:
Step-by-step explanation:
Just add the three sides P = side1 + side2 + side3
Don't let the 'x' terms confuse you, they are just numbers times 'x'
P = 3x+1/2 + 2x+1/4 + x+1/2
= 6x + 5/4
P = 6x + 1&1/4
Pisces is replacing paving stones for her inground pool. Her pool is 10m by 5m and is surrounded by a 1 1/2 border of paving stone. If each paving stone was 25 cm by 40 cm, in theory, how many paving stones will she need?
Answers
Answer:
The number of paving stones she needs is 540 paving stone
Step-by-step explanation:
The given dimensions of Pisces' inground pool = 10 m by 5 m
The thickness of the border surrounding the pool = 1 1/2
The dimensions of each paving stone = 25 cm by 40 cm = 0.25 m by 0.4 m
The length dimension of the pool and border = 10 + 2 × 1 1/2 = 13 m
The width dimension of the pool = 5 + 2 × 1 1/2 = 8 m
The total area of the paving stone, [tex]T_A[/tex] = Area of pool + border - Area of pool
∴ [tex]T_A[/tex] = 13 m × 8 m - 10 m × 5 m = 54 m²
The total area of the paving stone = 54 m²
The area of each paving stone, [tex]A_{EP}[/tex] = 0.25 m × 0.4 m = 0.1 m²/paving stone
The number of paving stones she needs, n = (The total area of the paving stone)/(The area of each paving stone)
∴ n = 54 m²/(0.1 m²/paving stone) = 540 paving stone.
For each triangle find the value of x
Answers
Answer:
x = 20
Step-by-step explanation:
The sum of the angles in a triangle is 180. A right triangle has one angle of 90. Thus, the sum of the other two angles will be 90. So, 90+31 = 121 and 180-121 = 59. (3x-1) = 59. Solve for x. This would mean that x would be 20. 3*20 = 60 and 60-1 = 59. All the angles add together would get 180: 59+90+31.

The measure of ∠ABD is (0.18x+56)° and the measure of ∠CBD is (0.07x+46)°. Find the value of x.
Answers
Answer:
x = 312
Step-by-step explanation:
We know that ∠ABD and ∠CBD are supplementary, meaning their measures add up to 180°. We can use this knowledge to put both measures into an equation.
[tex](0.18x+56) + (0.07x+46)= 180[/tex]
Simplify.
[tex]0.18x+56 + 0.07x+46= 180[/tex]
Simplify.
[tex]0.25x + 102 = 180[/tex]
Subtract 102.
[tex]0.25x = 180 - 102[/tex]
Simplify.
[tex]0.25x = 78[/tex]
Divide by 0.25
[tex]x = \frac{78}{0.25}[/tex]
Simplify.
[tex]x = 312[/tex]

A 23.7-foot tall flagpole casts a 42-foot shadow. What is the angle that the sun hits the flagpole? Express your answer in DMS
Answers
Answer:
60.6°
Step-by-step explanation:
Using trigonometry :
Opposite = Height of shadow = 42 feets
Adjacent = height of flagpole = 23.7 feets
Tan θ = opposite / Adjacent
Tan θ = height of shadow / height of flagpole
Tan θ = 42 / 23.7
Tan θ = 1.7721518
θ = tan^-1(1.7721518)
θ = 60.56
θ = 60.6°

A box contains four equal-sized cards labeled 1 , 3, 5, and 7. Tim will select one card from the box. What is the probability that Tim will select a card labeled 3?
Answers
Answer: 1/4
Step-by-step explanation:
Since the box box contains four equal-sized cards labeled 1 , 3, 5, and 7. The probability of selecting any number out of the four numbers will be 1/4 if they are selected once.
If Tim selects one card from the box, the probability that Tim will select a card labeled 3 will be: = 1/4
This is because 3 only occurs once and there are 4 numbers in total.
