Joey built a skateboarding ramp. The base of the ramp along the ground is 13 feet, and the top of the ramp is 7 feet off the ground. What is the length of the ramp's incline?
Answer:
14.77 feet
Step-by-step explanation:
Using the pythagoras theorem to get the length of the ramp
l² = 13² + 7²
l is the length of the ramp
l² = 169 + 49
l² = 218
l = √218
l = 14.77 feet
Hence the length of the ram is 14.77 feet

9.5=25/t+(-8) helppppppppp
Answer:
437.5Step-by-step explanation:
I will REALLY answer your question :)
9.5 = 25/t + -8
The first step here is to simplify t + -8. If you add a negative of something, you also subtract. This can be rewritten as:
9.5 = 25/t - 8
Now, we need to add 8 to undo the subtraction.
17.5 = 25/t
Now, to undo the division, we will multiply the whole equation by 25.
17.5 x 25 = 437.5
In the triangle ABC , Angle A = 46° and Angle B = 83°. How large is the exterior angle at C?
This is a problem with no diagram
Answer:
180 - 46 - 83 = 51 is the measure of angle C
the exterior angle at angle C, and angle C, are supplementary. since angle C is 51 because of the interior angle triangle sum theorem, then the exterior angle is: 180 -51 = 129 degrees.

Deon has taken a car loan for $1800. To pay the loan off in 12 months, how much would he have to pay per month?
Variable: x = amount to pay per month
Answer:
$150 per month
Step-by-step explanation:
If you divided 1800 by 12 you will get 150 so therefore he needs to pay $150 per month.
In a standard deck of cards, what is the probability of drawing a card with the suit of clubs?
Answer (round) to the hundredth place value.
Answer:
[tex]\frac{1}{4}[/tex]
= 0.25
Step-by-step explanation:
In a standard deck of cards, there are 52 cards. The standard deck of cards also has 13 clubs. Probability is;
[tex]\frac{wanted- outcomes}{total- outcomes}[/tex]
The wanted outcomes is a clubs, the total outcomes are the total number of cards in the deck, hence;
[tex]\frac{13}{52}[/tex]
Simplify;
[tex]\frac{1}{4}[/tex]
Point S is on line segment \overline{RT}
. Given ST=3x-8,ST=3x−8, RT=4x,RT=4x, and RS=4x-7,RS=4x−7, determine the numerical length of \overline{RT}.
RT
.
.
Answer:
RT = 20
Step-by-step explanation:
Point S is on line segment
R------------S------------T
RS + ST = RT
Given
ST=3x-8
RT=4x
RS=4x-7,
Step 1
We find x
4x - 7 + 3x - 8 = 4x
4x + 3x -7 - 8 = 4x
7x - 15 = 4x
7x - 4x = 15
3x = 15
x = 15/3
x = 5
Step 2
We find RT
RT = 4x
x = 5
RT = 4 × 5
RT = 20
The numerical length of RT is 20

A square has a side length of 13 meters. What is the area of the square?
If the dimensions of the square are doubled, what will be the area of the new square?
Answer:
Area of original = 169m^2
Area of new = 676m^2
Step-by-step explanation:
Area of a square = (length of side)^2
13^2 = 13 * 13 = 169
If the dimension is doubled:
(2*13)^2 = 26^2 = 676

) Luci Lulu opened a cookie store in the mall. She found that the relationship between the price of a cookie, p, and the number of cookies sold, x, is given by the linear relationship x = −2000 p + 4000 . Find the maximum revenue Luci can make selling cookies in one day
Answer:
The maximum revenue Luci can make selling cookies in one day is $4,004,000.
Step-by-step explanation:
Given;
x = −2000 p + 4000 ..................... (1)
Revenue = xp
Revenue = (−2000 p + 4000)p =
Revenue = −2000p^2 + 4000p .................... (2)
The price at which Luci will the maximum profit can be calculated by finding the derivative of equation (2), equating to 0, and then solve for p as follows:
−4000p + 4000 = 0
4000 = 4000p
p = 4000 / 4000
p = 1
This implies that the price at which Luci will the maximum profit is $1.
Substituting p = 1 into equation (2) to obtain the maximum revenue Luci can make selling cookies in one day, we have:
Revenue = (−2000 * 1)^2 + (4000 * 1)
Revenue = −2000^2 + 4000
Revenue = 4,000,000 + 4000
Revenue = 4,004,000
Therefore, the maximum revenue Luci can make selling cookies in one day is $4,004,000.

The lines AB and CB intersect at B
(a) Find the co-ordinates of the midpoint of AB
(b) Find the equation of the line CB
Step-by-step explanation:
Soln
given,
from the figure
coordinate of B is (5,3),
A(7,0) and C(0,4)
A. solution
let, M(x,y) be the mid point of AB
A(7,0) = (x1,y1)
B(5,3) = (x2,y2)
we know
x = (x2+x1)/2
or, x = (5+7)/2
or, x = 12/2
or, x = 6
and for y
y = (y2+y1)/2
or, y = (3+0)/2
or, y = 3/2
therefore M(x,y) = (6,3/2)
B. solution
let,
C(0,4) = (x1,y1)
B(5,3) = (x2,y2)
equation of line is ;
(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1)
or, (y - 4)/(x -0) = (3 - 4)/(5 - 0)
or, (y - 4)/(x - 0) = -1 / 5
by cross multiply
or, 5×(y - 4) = -1×(x)
or, 5y - 20 = -x
or, x + 5y = 20 is the required equation.
