Step-by-step explanation:
The American National Standards Institute specifications state that the
maximum slope of a wheelchair ramp should be one twelfth i.
The new ramp measures 5 feet high at its highest point and stretches
50 feet horizontally. Will this ramp pass specifications?
Answer:
No.
Step-by-step explanation:
Given that :
Maximum accepted Ramp slope = 1/12
A new ramp with :
Height range = 5 feets
Horizontal stretch = 50 feets
Th slope = Rise / Run = Height range / horizontal stretch = 5 / 50 = 1 / 10
1 / 10 > 1 / 12
This means the new ramp's slope is greater than than the maximum slope specification ; and hence not acceptable
How many solutions will each system of linear equation have?
Answer:
The top system of equations has one solution, the middle system has infinitely many, and the bottom system has no solution.
Step-by-step explanation:
We can immediately see the top system has one solution because the two equations have different slopes.
For the middle system, we can rearrange terms and multiply by 3 to get that the equations are the same line, so there are infinitely many solutions.
Finally, we can move the -2x to the other side in the first equation of the bottom system to get 2x+y=5. But it also equals -7 from the second equation! This is impossible, so there are no solutions to the bottom system.

Can someone help me solve this geometry problem down below?
Answer:
x = 29
Step-by-step explanation:
Given that both triangles are congruent to each other, therefore, their corresponding angles are congruent as well. This means all three angles in one is the same as all three corresponding angles of the other.
Therefore:
m<CAB = m<CDE = 74°
m<ABC = 2x (given)
m<BCA = 48° (given)
Thus:
m<CAB + m<ABC + m<BCA = 180° (sum of triangle)
Substitute
74 + 2x + 48 = 180
Add like terms
2x + 122 = 180
2x + 122 - 122 = 180 - 122
2x = 58
2x/2 = 58/2
x = 29

Find the value of y.
Answer:
[tex]y=2\sqrt{2}[/tex]
Step-by-step explanation:
The Pythagorean theorem is a theorem that can be applied to the sides of a right triangle. Please note that a right angle refers to an angle with a measure of (90) degrees. A box around an angle shows that the angle is a right angle, or has a measure of (90) degrees. The Pythagorean theorem states the following,
[tex]a^2+b^2=c^2[/tex]
Where (a) and (b) are the legs of the triangle, or the side adjacent to the right angle in the right triangle. (c) is the side opposite the right angle, or the hypotenuse of the triangle. One can apply this theorem to the smallest triangle in the diagram to find (y),
[tex]a^2+b^2=c^2[/tex]
Substitute,
[tex](1)^2+(y)^2=(3)^2[/tex]
Simplify,
[tex](1)^2+(y)^2=(3)^2[/tex]
[tex]1+y^2=9[/tex]
Inverse operations,
[tex]1+y^2=9[/tex]
[tex]y^2=8[/tex]
[tex]y=\sqrt{8}[/tex]
Take a factor from out of the square root. Remember that a number times itself under the radical is equal to the number. This can be simply stated as the following: ([tex]\sqrt{a*a}=a[/tex]),
[tex]y=\sqrt{8}[/tex]
[tex]8=2*2*2[/tex]
[tex]y=\sqrt{8}[/tex]
[tex]y=\sqrt{2*2*2}[/tex]
[tex]y=2\sqrt{2}[/tex]
Help!!! Will mark brainiest! Wrong answers will be reported, thx!
Answer:
(-1, -9/2) minimum true
1/2 (x+1)^2 -9/2 is the vertex form false
the axis of symmetry is at the x value of the vertex x=-1 false
The parabola opens up since the x^2 coefficient is positive false
x=-4 x=2 true
Step-by-step explanation:
f(x) = 1/2x^2 +x - 4
Factor out 1/2
f(x) = 1/2 (x^2 +2x - 8)
Factor
f(x) = 1/2 ( x+4)(x-2)
Finding the zeros
0= 1/2 ( x+4)(x-2)
Using the zero product property
x+4 = 0 x-2=0
x=-4 x=2
The vertex is 1/2 way between the zeros
(-4+2)/2 = -2/2 = -1
f(-1) = 1/2 (-1+4) (-1-2) = 1/2(3)(-3) =-9/2
The vertex is (-1, -9/2)
The parabola opens up since the x^2 coefficient is positive so this is the minimum
f(x) = 1/2 (x+1)^2 -9/2 is the vertex form
the axis of symmetry is at the x value of the vertex x=-1

Which polynomial is prime?
Plz help!
what is the solution for this equation?
In(x+6)-in(2x-1)=0
answers in the image!
Answer:
x=7
Step-by-step explanation:
ln(x+6)-ln(2x-1)=0
add ln(2x-1) to each side
ln(x+6) = ln(2x-1)
Raise each side to the base e
e^ln(x+6) = e^ln(2x-1)
x+6 = 2x-1
Subtract x from each side
x+6-x = 2x-1-x
6 = x-1
Add 1 to each side
6+1 = x-1+1
7=x

Yanni read 24 pages of
a book. One third of the book is
still left to read. How many
pages are there in the
whole book?
Answer:
36 pages
Step-by-step explanation:
If one third of the book is left to read until completion, then Yanni has read two thirds of the book so far.
24 pages is equal to two thirds, so one third will be half of this; 12 pages.
The whole book is three thirds, so 12 * 3, which is 36 pages

Could someone possibly help me
Answer:
D) 0
Step-by-step explanation:
The statement says that some number is greater than -6. When the symbol is flipped to the left it means greater than and when it is the other way, <, it is less than. 0 is greater than -6, therefore the statement is made true. While it may seem like 0 is actually smaller this is not the case because the 6 is negative. That means that any number closer to positive numbers is larger.
The millage rate is the amount of property tax per $1000 of the taxable value of
a home. For a certain county the millage rate is 29 mil. A city within the county
also imposes a flat fee of $101 per home.
a. Write a function representing the total amount of property tax T(x) for a home
with a taxable value of x thousand dollars.
b. Write an equation for T
-1(x).
c. What does the inverse function represent in the context of this problem?
9514 1404 393
Answer:
a. T(x) = 29x +101
b. T^-1(x) = (x -101)/29
c. the value of the home in thousands as a function of the tax on it
Step-by-step explanation:
a. The tax is $101 plus $29 per thousand of value. x is the value in thousands, so the tax is ...
T(x) = 29x +101
__
b. The inverse function can be found by solving ...
x = T(y)
x = 29y +101
x -101 = 29y
y = (x -101)/29
T^-1(x) = (x -101)/29
__
c. The function tells you the tax on a home worth x thousands.
The inverse function tells you the worth of the home in thousands when the tax on it is x.
Allen earns $7 an hour to wait tables at a restaurant. In addition, he makes an $8 tip from each
table. He waited 6 tables and made $104. Which equation(s) below could be used to find the
total number of hours he worked? How many hours did he work?
Answer:
he worked 8 hours
Step-by-step explanation:
104= 8 x 6 + 7x
104= 48 + 7x
56= 7x
x=8
104 - 48= 56
56/7
Answer:
Equation - 7h + 8t = $104
Hours Worked = 8
Step-by-step explanation:
First, let's create an equation!
7h + 8t = $104 (Our variables are h = # of hours, and t = # of tables)
Now, we have to input what we know! We know that Allen worked 6 tables.
7h + 8(6) = $104
and finally we can solve this equation!
7h + 48 = $104
-48 -48
7h = 56
÷7 ÷7
h = 8
In conclusion, Allen worked 8 hours!
Hope this Helps! :)

Answer:
the first is two points; the second is the interval between (and including) those two points
Step-by-step explanation:
The equation ...
4 = |x +5|
has two solutions:
x ∈ {-9, -1}
__
In the interval between those two solutions the absolute value expression is less than 4. So, the second expression has a solution that is a range of values. Those values are in the interval whose boundaries are -9 and -1.
x ∈ [-9, -1]
__
The solution to the second expression can be found as ...
4 ≥ |x +5|
4 ≥ x+5 ≥ -4 . . . . express as a compound inequality
-1 ≥ x ≥ -9 . . . . . . subtract 5
__
The attached graph shows the two solutions. The solution to the first equation is the pair of (black) lines, x=-9 and x=-1. The solution to the second equation is the (orange) shaded interval -9 ≤ x ≤ -1.

Marina spent $13.50 at the grocery store. She bought pears,
kiwis, and pineapples. Pears cost $0.50 each, pineapples cost
$1.50 each, and kiwis are $0.30 each. How many of each kind of
fruit did she buy if she bought 9 more pears than pineapples and
2 fewer kiwis than pears?
Answer:
Step-by-step explanation:
First we are going to set up our general equation (what is being asked of us). Marina bought pears, pineapples, and kiwis and spent $13.50 on them. The equation for that is
pi + pe + k = 13.5
Now we need to figure out how to eliminate most of those unknowns and put 2 of them in terms of the other 1. It looks like everything is based on the number of pineapples she bought. First it says she bought 9 more pears than pineapples, so obviously, there are more pears than pineapple, so
pe = pi + 9
And if she bought 2 fewer than kiwis thatn pears, and pears = pi + 9, then the number of kiwis she bought was
kiwis = (pi + 9) - 2 which simplifies down to pi + 7.
Now we'll put all of those into the equation:
pi + (pi + 9) + (pi + 7) = 13.5 What I have done is create an equation that is not parallel. In other words, I have the NUMBER of the kinds of fruit on one side of the equation, and the COST of the fruit on the other side, and that's not cool. We have to have EITHER a NUMBER of fruit equation OR a COST of fruit equation, but not both in the same equation. To amend that, we will figure in the cost of each of these kinds of fruit by the correcpsonding number of that kind of fruit. Pineapples cost $1.50 each, so the expression for pineapples is 1.5pi; pears cost $.50 each, so the expression for pears is.5(pi + 9); kiwis cost $.30 each, so the expression for kiwis is .3(pi + 7). NOW we can set up the equation:
1.5pi + .5(pi + 9) + .3(pi + 7) = 13.5 and simplify:
1.5pi + .5pi + 4.5 + .3pi + 2.1 = 13.5 and simplify some more by combining like terms:
2.3pi = 6.9 so
pi = 3. Ok we have 3 pineapples. Now we go back up to the expression for pears:
pe = pi + 9 so
pears = 12. Now we go back to the expression for kiwis:
k = pi + 7 so
kiwis = 10. And there you go!
