A skateboarding ramp is 17 in high and rises at an angle of 19"How long is the base of the ramp ? Round to nearest inch
Answer: 39.3 inches
Step-by-step explanation:
Let x represent the length of base of ramp.
We have been given that a skateboarding ramp is 12 in high and rises at an angle of 17 degrees. We are asked to find the base of the skateboard.
The height of ramp, the base of ramp and angle of elevation make a right triangle with ground, where, 12 inch is opposite side and base of ramp is adjacent side of angle of elevation.
Therefore, the base of ramp is 39.3 inches long.

What is a explication for linear relationship?
Step-by-step explanation:
A linear equation in two variables can be described as a linear relationship between x and y, that is, two variables in which the value of one of them (usually y) depends on the value of the other one (usually x). In this case, x is the independent variable, and y depends on it, so y is called the dependent variable

find the value of x plsss helpp
Answer:
90 + 29 + x = 180
119 + x = 180
-119 -119
X = 61 degrees
A triangle will always equal 180 degrees.
Given that there is a right triangle it is 90 degrees, also given that 29 degrees is there we add those and add x (the unknown degree) to equal 180 degrees.
What is the solution to
(y = 3x - 30
x2 + y2 = 100
Answer:
x = 20
y = 30
Step-by-step explanation:
Answer:
x = 20
y = 30
Step-by-step explanation:
y = 3x - 30
2x + 2y = 100
2x + 2(3x - 30) = 100
2x + 6x - 60 = 100
8x - 60 = 100
8x = 160
x = 20
y = 3(20) - 30
y = 60 - 30
y = 30
A pendulum is constructed by attaching a 4m rope to a bowling ball. It is then displaced 2m to one side and released.
Ignoring all effects of friction, and without knots,
a) Determine the period of the pendulum. Round to one decimal place.
Answer:
T = 4.0 s
Step-by-step explanation:
The period of a simple pendulum is given by
[tex]period = 2\pi \sqrt{ \frac{l}{g} } [/tex]
where l = length of the pendulum
= 4 m
g = acceleration due to gravity
= 9.8 m/s^2
[tex]period = 2\pi \sqrt{ \frac{(4 \: m)}{(9.8 \: \frac{m}{ {s}^{2} } )} } = 4.0 \: s[/tex]
How many cubes with side lengths of 1/2 cm can fit inside the rectangular prism
Answer:
7/2 or 3.5 inches
Step-by-step explanation:
The volume of the rectangle=
length×width×height, so
V=1/2×2×7/2
V=1×7/2
V=7/2 cubic inches
Next, Volume of the cube=
side^3, or side×side×side
V=1/2×1/2×1/2
V=1/8 cubic inches
First question,
To find how many cubes with the side of 1/2 length that fir into the rectangular prism, take:
7/2÷1/8
=7/2×8
=28 cubes. As a result, there are 28 cubes that will fit into the prism
Second question,
The volume of the person is 7/2 cubic inches or 3.5 cubic inches. Hope it help!

What is the area of F?
Answer:
area of circle F = 9 pi
Step-by-step explanation:
An interesting problem, combining geometry and algebra.
It has not been indicated, but it will be assumed that GH is a tangent to the circle F, hence the tangent-secant theorem from point H applies.
Produce HF to point E on the circumference such that EJ forms a diameter of circle F.
By the tangent-secant theorem,
HG^2 = HJ*HE
Substitute given values,
(x+2)^2 = 2*(2*(2x-1)+2)
Expand algebraically
x^2+4x+4 = 2(4x-2+2)
x^2+4x+4 = 8x
x^2-4x+4 = 0
Factor
(x-2)^2 = 0
=>
x=2
Substitute x=2 into radius FG = 2(x)-1 = 3
Therefore area of circle F
= pi r^2
= pi (3)^2
= 9 pi

Estimate 12.826+2.93 by first rounding each number to the nearest tenth.
I need the right answer
Answer:
15.8
Step-by-step explanation:
Well if you had to round to the nearest tenth then 12.896 would be 12.9 and 2.93 would be 2.9. The reason is if it is below 5 then you would round down if it is more than 5 then round up. Then add the two numbers which are 12.9+2.9=15.8
Hope it helps. Sorry if it does not!

What is (f-g)(x) f(x)= x^4-3x^2+5x-7 g(x)= x^3-3x^2+3x-1
Answer:
x^4 - x^3 + 2x -6
Step-by-step explanation:
(f-g)(x) = x^4-3x^2+5x-7 - ( x^3-3x^2+3x-1 ) = x^4 - 3x^2+5x-7 - x^3 + 3x^2 - 3x + 1 = x^4 - x^3 + 2x -6
Step-by-step explanation:
x^4-3x^2+5x-7 – x^3-3x^2+3x-1
x^4-3x^2+5x-7 – x^3+3x^2-3x+1
x^4-3x^2+3x^2-3x +5x -x^3 -7+1
x^4+2x -x^3 -6
x^4-x^3+2x-6

How do I find the surface area of a trapezoid prism
PLEASE HELP ME! THIS IS DUE TODAY, AND I WILL MARK BRAINLEST.
Answer:
The correct answer is B: XY=4 cm
Step-by-step explanation:
This is correct because the triangles are both leaning in the same direction so the sides are congruent as stated. Congruent, means that they are equal to each other in other words symmetrical. Because of this, they are the same triangle so where 4 is on the first triangle, it will appear on the same side on the other triangle. This means the answer is B. XY = 4 cm
Answer:
The second one
Step-by-step explanation:
It cant be the first because YZ=4cm
cant be the third because m∠Y= 50°
cant be the forth one because m∠Z= 70°
so, it has to be the second one because XY≅AB
so, if AB=4cm then XY=4cm

Help plz i will give brainlest
Can someone please solve these?
Answer:
Step-by-step explanation:
h = -6[tex]t^{2}[/tex] +20t + 4
I will use calculus, maybe that's not how you're supposed to do this
-12t +20 =0
12t = 20
t = 20 /12
t = 1 [tex]\frac{8}{12}[/tex]
t = 1 [tex]\frac{2}{3}[/tex]
there will be a max at 1.6666666666 seconds
-6*[tex]1.6666666666666^{2}[/tex] + 20 * 1.6666666666 +4
= 16.666666666666 + 33.333333333333 + 4
= - 16[tex]\frac{2}{3}[/tex] + 33 [tex]\frac{1}{3}[/tex] + 4
= 20[tex]\frac{2}{3}[/tex] feet max height ( not too high, for a rocket)
time of flight:
0 = -6[tex]t^{2}[/tex] +20t + 4
use quadratic formula to find t
-20 +- sqrt [ [tex]20^{2}[/tex] - 4*(-6)*4 ] / 2*(-6)
-20 +- sqrt [400 + 96 ] / -12
-20 +- sqrt [496 ] / -12
-20 +- 22.27105 / -12
try the negative option 1st
-42.27105 / -12
3.522 seconds. time of flight
when will the rocket be at 12' ? :
12 = -6[tex]t^{2}[/tex] +20t + 4
0 = -6[tex]t^{2}[/tex] +20t -8
use quadratic formula again to find t
-20 +- sqrt [ [tex]20^{2}[/tex] - 4*(-6)*(-8) ] / 2*(-6)
-20 +- sqrt [ 400 - 192 ] / -12
-20 +- sqrt [208 ] / -12
-20 - 14.4222 / -12
-34.4222 / -12
2.8685 seconds ( on the way down)
and
-20 + 14.4222 / -12
-5.578 / - 12
0.4648 seconds ( on the way up )

Harish's soccer team is trying to raise $5,092 to travel to a tournament in Florida, so they decided to host a pancake breakfast. Each person must pay $38 for the breakfast. How many people need to attend their breakfast in order to raise $5,092?
Answer: 134 people
Step-by-step explanation:
Data: The soccer team needs to raise $5,092
They are hosting a pancake breakfast to do so and are charging $38 to do so
The number of people they need to attend their breakfast for the money to be raised: $x
Step one, make the equation
$38x=$5,092
Reason: Since we know that the number of people(x) times $38 will equal $5,092 so to put it into an equation will make it easier to solve.
Step two, Isolate x by dividing by 38 on both sides
$38x/38=$5,092/38=x=134
Reason: Since you are trying to find the number of people(x) you have to isolate it. the way to do that is by getting rid of the 38 next to it and by dividing, you cancel out the multplication and get rid of the 38. However, since what you do to one side you do to the other, you divide 5,092 by 38 to get the answer of 134.
Answer: 134 people
I hope this helps!
