Answer:
The equation for the price, as a function of time in hours is:
P(x) = 20*x for 0 ≤ x ≤ 2
P(x) = 40 + 10*(x - 2) for 2 ≤ x
Now, we want to evaluate this function in 40 mins.
we know that 1 hour = 60mins.
Then 40 mins = (40/60) hours = 0.67 hours.
Then we input this in our function, and because this is smaller than 2, we use the first piece of our function:
P(0.67) = 20*0.67 = 13.4
So in 40 mins, the charge will be 13.4 pesos.
What is f(-8) for the function f?

Given A(2,14), B(2,3), C(4,2), and D(14,2) what is the distance of CD?
Answer: CD = 10
Step-by-step explanation:
Subtract the smaller one from the larger one.
D(14, 2) - C(4, 2)
First, you subtract the x-values:
14 - 4 = 10
Then, you subtract your y-values:
2 - 2 = 0
Since the y-value is 0 (since it is a straight line), your distance of CD is 10.
Hope this helps!

Which situation represents causation rather than correlation?
A. as the number of injured players on the sports team increases the number of fans attending the teams game increases
B. as more swimsuits are sold by department stores more sailboats are rented at the marina
C. as more people carry their umbrellas to work more people dress and heavier clothing
D. as a total number of family member increases the amount of money that the family spends on food increases
Answer: D. as a total number of family member increases the amount of money that the family spends on food increases
Step-by-step explanation:
Correlation is used to describe the 5kinf of relation between two variables whereas causation is relationship between the cause and effect.'i.e. independent variable acts like a cause to effect the dependent variable.
This can be seen only in Option D. as it is very obvious that increase in family member will increase the cost of food.
Hence, there is direct effect of number of people on food's cost.
Rest of options represents correlation but not causation .
Hence, the correction option is D.
Given: ∠GHD and ∠EDH are right; GH ≅ ED Triangles G H D and E D H overlap and intersect at point F. The triangles share side H D. Sides G H and E D are congruent. angles G H D and E D H are right angles. Which relationship in the diagram is true ?
A. △GHD ≅ △EDH by SAS
B. △GHF ≅ △EDF by SSS
C. △FDH ≅ △FDE by ASA
D. △HFD ≅ △HFG by SSS
Answer:
A. △GHD ≅ △EDH by SAS
Step-by-step explanation:
This is right on edge. 2020
In triangles GHD and EDH angle GHD and angle EDH is congruent, side GH is congruent to the side ED, and side HD is congruent to side HD. So, from side angle side postulate triangle GHD and triangle EDH are congruent.
Given :
∠GHD and ∠EDH are rightGH ≅ ED Triangles G H D and E D H overlap and intersect at point F.The triangles share side H D. Sides G H and E D are congruent. angles G H D and E D H are right angles.In the Side Angle Side postulate, the two sides and the included angle of one triangle are congruent to the two sides and the included angle of another triangle.
Given that in triangles GHD and EDH angle GHD and angle EDH is congruent, side GH is congruent to the side ED, and side HD is congruent to side HD.
So, from side angle side postulate triangle GHD and triangle EDH are congruent. Therefore, the correct option is A).

A company that makes hair care products had 6,000 people try a new shampoo of the 6.000
people, 12 had a mild allergic reaction. What percent of the people had a mild allergic reaction
Using the percentage concept, it is found that 0.2% of the people had a mild allergic reaction.
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
In this problem, 12 out of 6000 people had a reaction, hence:
[tex]P = \frac{12}{6000} \times 100\% = 0.2\%[/tex]
0.2% of the people had a mild allergic reaction.

Which equation is equivalent to y=2/3x-6
A. 2x+3y=-6
B.3x-2y=6
C.3x-2y=12
D.2x-3y=18
Answer:
D. 2x-3y=18
Step-by-step explanation:
1. multiply both sides by 3 to get rid of the fraction
( 3)(y)=([tex]\frac{2}{3}[/tex]x -6)(3)
2. That gives 3y=2x-18
3. subtract 2x on both sides
3y=2x-18
-2x = -2x
3. that gives -2x+3y=-18
4. then multiply by -1 to make 2x positive
-1(-2x+3y=-18)
5. and that gives 2x-3y=18

You are running a 10 mile race. You run the first 3 miles in 24.7 minutes. Your goal is to finish the race in less than 1 hour and 20 minutes. What should you average running time (in minutes per mile) be for the remaining miles?
Answer:
Therefore you have to run every mile in ~ 8 minutes.
Step-by-step explanation:
10 miles - 3 miles = 7 miles left.
1 hour 20 minutes - 24.7 minutes= 80 minutes - 24.7 minutes
= 55.3 minutes left
Therefore, you have 55.3 minutes left to run 7 miles. But since you want to finish in LESS than 1 hour and 20 minutes, subtract the .3.
So:
7 miles = 55 minutes
1 mile x minutes
x minutes= 55 x 1 ÷ 7 miles
x minutes = 7.85
x minutes = ~ 8 minutes
Therefore you have to run every mile in ~ 8 minutes.
Hope this helps!
