Step-by-step explanation:
Here is the complete question
When Vlad moved to his new home a few years ago, there was a young oak tree in his backyard.
He measured it once a year and found that it grew by 26 centimeters each year. 4.5 years after he moved into the house, the tree was 292 centimeters tall.
1. How tall was the tree when Vlad moved into the house?
2. How many years passed from the time Vlad moved in until the tree was 357 centimeters tall?
The formula for calculating future value:
FV = P + (r x n)
FV = Future height of the tree
P = Present height of the tree
R = growth rate
N = number of years
292 = p + (26 x 4.5)
292 = p + 117
p = 292 - 117
p = 175 cm
b. 357 = 175 + (26 x n)
375 - 175 = 26n
182 = 26n
n = 182 / 26 = 7 years

Jane will rent a car for the weekend she can choose one of the two plans the first plan has an initial fee of $42 in cost of additional $.12 per mile driven the second plan has an initial fee of $55 in cost additional seven cents per mile driven
Answer:
260m
$73.2
Step-by-step explanation:
For what amount of driving do the plans cost the same?
What the cost when the two plans cost the same?
first plan = 42 + 0.12m
second plan = 55 + 0.07m
42 + 0.12m = 55 + 0.07m
collect like terms
55 - 42 = 0.12 - 0.07m
13 = 0.05m
m = 260
42 + 0.12(260) = 73.2
0.33+0.09= m mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
Answer:
0.42
Step-by-step explanation:
Add 9 to 3 to get 12, divide 12 by 100 and add it to 0.3 to get your answer.

A researcher places a radio advertisement offering $32 in exchange for participation in a short study. The researcher accepts the first nine people who respond to the advertisement. Which of the following statements is true about the sample?
It is a valid sample because the first nine people were selected to participate.
It is not a valid sample because it is not a random sample of the population.
It is a valid sample because money was offered to participants.
It is not a valid sample because it is only a short study.
Answer:
I am not sure if I am right, but in my opinion, it is a valid sample, since they are participating and getting paid, so I would personally go for the third option, but the decision is on you.

You are planning to build a walkway that surrounds the area of a rectangular garden. The width of the walkway around the
garden is the same on every side. Which of the following polynomials represents the total area of the garden and
walkway?
Answer:
B. (2x + 10)(2x + 9)
Step-by-step explanation:
Length (L) of the garden and walkway = x + 10 + x = (2x + 10) ft
Width (W) of the garden and walkway = x + 9 + x = (2x + 9)
Area of the garden and walkway = area of rectangle = L*W
= (2x + 10)(2x + 9)
The polynomial representing the total area of the garden and walkway = (2x + 10)(2x + 9)
Sum of twenty, use the numbers 0 - 9 so that each row column sum to 20. Diagonals are not included.
Answer:
where each row and column sum up to 20
2 4 6 8
4 2 6 8
6 6 4 4
8 8 4 0
Step-by-step explanation:
The sum of twenty using numbers 0 - 9
where each row and column sum up to 20
2 4 6 8
4 2 6 8
6 6 4 4
8 8 4 0
when you sum up each of the row or each of the column the sum = 20
given that the diagonals are not included the sum of diagonals > or < 20

Charlie is 4 more than twice as old as Frank. Frank is 3 years younger than Bob,
If Bob is 9 years old, how old is Charlie?
Answer:
16
Step-by-step explanation:
x + 3= 9
x = 6
2x + 4= 2*6 + 4
2x + 4 = 12 + 4
2x + 4 =16
Charlies 16
hope it helps
Answer: he is 16
Step-by-step explanation:
Let x = Frank's age
2x+4+ = Charlie's age
x+3+ = Bob's age
9 = Bob's age
x+3=9
x=6
2x+4=2⋅6+4
2x+4=12+4
2x+4=16
Charlie is 16

Area of a triangle: .5(b*h)
which means that
.5(4(x-1)*(2x+5))=30
mulitply the two equations
(4x-4)(2x+5) = 8x²+12x-20
distribute the 1/2
.5(8x²+12x-20)
4x²+6x-10 = 30
divide both sides by 2
2x²+3x-5= 15
move everything to one side
2x²+3x-20=0

Answer:
Blue: y = x² + 3
Purple: y = (x + 4)²
Step-by-step explanation:
The parabolas are "transformed", meaning they have been shifted on the coordinate grid. All parabolas will have the equation of "y = x²", any additional transformation will add onto that.
Blue: Looking at the red parabola, its lowest point is only three units down from the blue's lowest points. Meaning the blue parabola went only three units up. So you only have to do the "+ 3" in the equation.
Purple: Like in blue, we're gonna look at the purple's lowest point and compare it to red's lowest point. The purple parabola seems to have shifted only four units to the left. Though, instead of adding onto the equation like in the blue parabola, any changes on the x-axis will be put into parenthesis. IN ADDITION, the sign will be the opposite of what it is on the coordinate grid. For example, the purple parabola is on the -4 of the x-axis. Instead of putting "(x - 4)", we put "(x + 4)".
Try the next two problems on your own. They will be similarly structured to the two answers above. If you need more help, lemme know. :)

Dana rasied the score on a video game from 300 points to 390 points. By what percentage did Dana raise the score?
Answer: 30%
Step-by-step explanation:
First find the difference between the old score and the new:

= 90 points
To find the percentage increase, divide the difference by the original score:
= 90 / 300
= 30%
