Jane is a cliff diver and she is planning on jumping from a height of 747 feet and landing in the water below. She will end her dive 64 feet below sea level. What is the difference in height between her starting and ending points?
Answer:
811 feet
Step-by-step explanation:
When finding height difference, you use absolute value, so everything is positive. 747+64 = 811, so your answer is 811 feet.
Hope this helps!
Answer:
811ft
Step-by-step explanation:
Add 747+64 not negative positive

A store offers packing and mailing services to customers. The cost of shipping a box is a combination of a flat packing fee of $5 and an amount based on the weight in pounds of the box, $2.25 per pound. Which equation represents the shipping cost as a function of x, the weight in pounds?
f(x) = 2.25x + 5
f(x) = 5x + 2.25
f(x) = 2.25x − 5
f(x) = 5x − 2.25
Answer:
A. f(x) = 2.25x + 5

Let F = (2, 3). Find coordinates for three points that are equidistant from F and the y-axis. Write an equation that says P = (x, y) is equidistant from F and the y-axis
Answer:
The equation that says P is equidistant from F and the y-axis is [tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex].
(1, 0), (1, 3/2) and (1,6) are three points that are equdistant from F and the y-axis.
Step-by-step explanation:
Let [tex]F(x,y) = (2,3)[/tex] and [tex]R(x,y) =(0, y')[/tex], where [tex]P(x,y)[/tex] is a point that is equidistant from F and the y-axis. The following vectorial expression must be satisfied to get the location of that point:
[tex]F(x,y)-P(x,y) = P(x,y)-R(x,y)[/tex]
[tex]2\cdot P(x,y) = F(x,y)+R(x,y)[/tex]
[tex]P(x,y) = \frac{1}{2}\cdot F(x,y)+\frac{1}{2} \cdot R(x,y)[/tex] (1)
If we know that [tex]F(x,y) = (2,3)[/tex] and [tex]R(x,y) = (0,y')[/tex], then the resulting vectorial equation is:
[tex]P(x,y) = \left(1,\frac{3}{2} \right)+\left(0, \frac{y'}{2}\right)[/tex]
[tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex]
The equation that says P is equidistant from F and the y-axis is [tex]P(x,y) =\left(1,\frac{3+y'}{2} \right)[/tex].
If we know that [tex]y_{1}' = -3[/tex], [tex]y_{2}' = 0[/tex] and [tex]y_{3}' = 3[/tex], then the coordinates for three points that are equidistant from F and the y-axis:
[tex]P_{1}(x,y) = \left(1,\frac{3+y_{1}'}{2} \right)[/tex]
[tex]P_{1}(x,y) = (1,0)[/tex]
[tex]P_{2}(x,y) = \left(1,\frac{3+y_{2}'}{2} \right)[/tex]
[tex]P_{2}(x,y) = \left(1,\frac{3}{2} \right)[/tex]
[tex]P_{3}(x,y) = \left(1,\frac{3+y_{3}'}{2} \right)[/tex]
[tex]P_{3}(x,y) = \left(1,6 \right)[/tex]
(1, 0), (1, 3/2) and (1,6) are three points that are equdistant from F and the y-axis.

a sofa set was bought for rs.9000and sold at a loss of 25 percent . what was the selling price ?
chapter in maths is comparing quantities
need answer fast pls help . will give full stars !
Answer:
selling price was 6750
Step-by-step explanation:
9000 x 0.25 = 2250
9000 - 2250 = 6750
Answer:
=rs. 6750
Step-by-step explanation:
marked price= 9000 = 100%
selling price= ? = 75%
loss= ? = 25%
as he made a loss it means that he sold the sofa for a lower price hence the selling price will be lower than the marked price.
selling price = if 100% = 9000
what about 75%?
75% x 9000
100%
=rs.6750

n is an integer. Prove that (2n+1)(n+3)+(2n+1)(n-2) is not a multiple of 2. thanks.
Answer:
(2n + 1)(n + 3) + (2n + 1)(n - 2)
= (2n + 1)(n + 3 + n - 2)
= (2n + 1)2n + 1)
= 4n² + 4n + 1
= 2(2n² + 2n) + 1
can see 2(2n² + 2n) is a multiple of 2 but 1 isnt a multiple of 2
=> 2(2n² + 2n) + 1 is not a multiple of 2
=> (2n + 1)(n + 3) + (2n + 1)(n - 2) is not a multiple of 2

Each angle of the equilateral triangle in the figure has measure (2x – 9)°. Determine the value of x.
A) x = 25.5
B) x = 34.5
C) x = 69
D) x = 60
Answer:
34.5
Step-by-step explanation:
An easy way to find this out is plug in all the answers into our equation until we get 180. So here's what you do:
A) X=25.5
So put that in the equation replacing x like this : 2(25.5)-9 =42 then multiply by three which = 126, So, A) is not our answer, now do it with the rest until you get 180,
2(34.5)-9=60 60x3=180 so your answer will be the number you plug in aka:34.5

daniel watched a beetle and a spider on the sidewalk. the beetle crawled 1/2 of a yard and the spider crawled 1/6 of a yard how much farther did the beetle crawl than the spider
Answer:
2 yards
Step-by-step explanation:
The beetle crawled 3 times more than the spider crawled.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that daniel watched a beetle and a spider on the sidewalk. the beetle crawled 1/2 of a yard and the spider crawled 1/6 of a yard.
The beetle crawled how many times is calculated as:-
Beetle crawled = ( 1 / 2 ) ÷ (1 / 6) x Spider crawled
Beetle crawled = 3 x Spider crawled
Therefore, the beetle crawled 3 times more than the spider crawled.

What is the final amount if 1015 is decreased by 6% followed by a 19% increase?
Give your answer rounded to 2 DP. plse be QUICK
Answer:
1135.38
Step-by-step explanation:
Original amount = 1015;
First decrease = 6%
Followed by an increase = 19%
Unknown:
Final amount:
Solution:
If 100% of a value implies multiplying by 1;
6% decrease = 0.94
19% increase = 1.19
Now;
Final amount = 1015 x 0.94 x 1.19 = 1135.38
