Answer:
25
I hope this helps.
Answer:
Amy worked 25 hours
Step-by-step explanation:
To first start off we have the equation 12.5h= 312.5
from here, we divide by 12.5 to have h by itself inorder to find how many hours she worked as h stands for hours.
Once you divide 312.5 by 12.5 you get h=25
Once again, the h stands for hours, so this means that Amy worked 25 hours, and that for one hour she earned 12.5 dollars.
If you want to find how much money she made for example in 5 hours, all you have to do is plug in the 5 for h and multiply it by 12.50 to get how much she earned in that certain amount of hours!
Hope this helps! If you have any questions, feel free to ask! :)

What are the two values on a number line that are a
distance of 5 from 0?
Answer:
the two values that are a distance of 5 from 0 are -5 and 5.
Step-by-step explanation:
if you look at a number line, you will see that the number 0 is in the middle. if you count 5 from each side, it's -5 and 5. any other number would have a greater distance than 5 from 0. hope this helps.

Find the common ratio of the geometric sequence 17,-51,153,...
Answer:
The answer is - 3Step-by-step explanation:
To find the common ratio ( r) of a given sequence , divide the previous term by the next term.
That's
[tex]r = - \frac{51}{17} = - 3 \: \: \\ or \\ r = - \frac{153}{51} = - 3[/tex]
Since the common ratio is the same for any of the terms chosen , the common ratio is - 3

Maggie's brother is 5 years younger than twice her age. The sum of their ages is 22.
How old is Maggie?
Answer:
9 years old
Step-by-step explanation:
Let maggie's age be m,
and let maggie's brother's age be b
b = 2m - 5,
m + b = 22
Substitute "2m - 5" for b in the second equation (substitution)
m + (2m - 5) = 22 -> Remove parenthesis
m + 2m - 5 = 22 -> Combine like terms
3m = 22 + 5 = 27 -> Divide either side by 3
m = 27/3 = 9
Solution: Maggie is 9 years old

Over what interval is the graph of y=−2 +|x− 2| increasing?
a. (2, ∞)
b. (−2, ∞)
c. (−∞, −2)
d. (−∞, 2)
Answer:
(2, ∞)
Step-by-step explanation:
An absolute value graph at (0, 0) is an up facing V shape graph. After a few transformation, according to the equation y = −2 + |x− 2|, we have our vertex at (0, - 2). It remains at up facing V graph.
x - h,
x - 2,
x - (+ 2),
h = 2
Therefore our slope is 2, with out vertex at (0, - 2). If we plot our graph, you can see that on the interval (2, ∞) the graph increases...
If _A = 28°, what must the measure of D be in order for A ABC to be similar
to A DEF?
A. 14
B. 28
C. 31
D. 62°
Answer:
62°
Step-by-step explanation:
If it is a right triangle, subtract 90, from 180 and then subtract 28 to get D. D should = 62°
D must be equal to 28° in order for triangle ABC to be similar to triangle DEF.
The correct answer is option B.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
We know that if two angles of a triangle are congruent to two angles of another triangle, then the triangles are similar.
Since angle A is congruent to angle D, we need to find the value of D that makes this true.
Therefore,
D must be equal to 28° in order for triangle ABC to be similar to triangle DEF.

Find the linear function with the following properties.
f(−4)=6
Slope of f=−6
Given:
f(−4)=6
Slope of f=−6
To find:
The linear function with the given properties.
Solution:
We have,
f(−4)=6
It means, the value of linear function is 6 at x=-4. So, the linear function passes through the point (-4,6).
Slope of f=−6
The point slope form of a linear function is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope of the linear function.
On substituting the values, we get
[tex]y-6=(-6)(x-(-4))[/tex]
[tex]y-6=-6(x+4)[/tex]
[tex]y-6=-6x-24[/tex]
Add 6 on both sides.
[tex]y-6+6=-6x-24+6[/tex]
[tex]y=-6x-18[/tex]
The function form of this linear equation is
[tex]f(x)=-6x-18[/tex]
Therefore, the required function is [tex]f(x)=-6x-18[/tex].

The length of the window is 2m longer than its width and the area is 32m^
Answer:
X¹= -2 + 2√33
X²= -2 - 2√33
Step-by-step explanation:
X × (X+2) = 32
X² + 2X = 32
X² + 2X - 32= 0
Δ=132
X= -2 ± 2√33
X¹= -2 + 2√33
X²= -2 - 2√33

bc = ad
solve for a
Answer:
[tex]\huge\boxed{a=\frac{bc}{d}}[/tex]
Step-by-step explanation:
In order to find the value of a when we have the equation [tex]bc=ad[/tex], our goal is to isolate a on one side.
The key question here is: what's stopping a from being alone on one side? That would be it being multiplied by [tex]d[/tex]. If we were able to remove the d, we would have a by itself.
Since we are multiplying a and d, we can get rid of the d by dividing both sides by d.
We have to divide both sides of the equation by the same value in order to keep it equal.
[tex]bc \div d = ad \div d\\\\\frac{bc}{d}=a\\\\a = \frac{bc}{d}[/tex]

Simplify the following expression.
44[(9 + 3) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (3.5 2)) - 9]
The value of the expression is 2419.
The required answer is 2400.5
What is simplification?Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube roots, plus and minus.
Now the given expression is,
44[(9 + 3) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (3.5 - 2)) - 9]
It can be simplified using PEMDAS rule.
P is parenthesis
E is exponents
M is multiplication
D is division
A is addition
S is subtraction
Firstly we will solve parenthesis, thus
44[(9 + 3) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (3.5 - 2)) - 9]
= 44[(12) + 72 - 6 * 2.5 - 19] - [42 - 3(77 + (1.5)) - 9]
= 44[12 + 72 - 6 * 2.5 - 19] - [42 - 3(78.5) - 9]
Now we will solve multiplication,
= 44[12 + 72 - 15 - 19] - [42 - 235.5 - 9]
Now we will solve addition,
= 44[84 - 15 - 19] - [42 - 235.5 - 9]
Now we will solve subtraction,
= 44[84 -34] - [42 - 244.5]
= 44[50] - [42 - 244.5]
= 44[50] - [-200.5]
= 2200+ 200.5
= 2400.5
Thus, the required answer is 2400.5

Bob is trying to see if his shadow is longer than Kevin’s. Kevin is 3 feet tall, and Bob is 2½ feet tall. Kevin’s shadow is 5 feet long. Help Bob find the length of his shadow
Given parameters:
Height of Kevin = 3ft
Height of Bob = 2.5ft
Hieght of Kevin's shadow = 5ft
Unknown:
Length of Bob's shadow = ?
We can simply set up simple ratio to solve this problem.
The ratio of Kevin's height to Bob's height is 3 : 2.5
The ratio of their shadow should also be 5: Bob's shadow height
Equating the two of them should give a fairly constant ratio;
[tex]\frac{3}{2.5} = \frac{5}{Bob}[/tex]
3Bob = 5 x 2.5
Bob's shadow height = [tex]\frac{5 x 2.5}{3}[/tex] = 4.2ft
The height of Bob's shadow is 4.2ft.
