Answer:
$132
Step-by-step explanation:
[] First, we will set up an equation for Ross.
-> We will use slope-intercept form (see attached)
-> The slope:
[tex]\frac{y_{2} -y_{1}}{x_{2} -x_{1} }[/tex] = [tex]\frac{81-40.5}{6-3}[/tex]=[tex]\frac{40.5}{3}[/tex]=13.5
-> The y-intercept:
y = 13.5x + b
(81) = 13.5(6) + b
81 = 81 + b
0 = b
-> Final equation:
y = 13.5x
-> For 8 hours, we will plug in 8 as the x.
y= 13.5(8)
y = $108
[] Joey earns 3 dollars more,
y = (13.5 + 3)x
-> Now we will plug 8 into the equation as x,
y = $132
Have a nice day!

Answer:
132
Step-by-step explanation:
why is it important to represent fractions in division with models?
Answer:
Fractions help children understand the nature of numbers and their interactions (e.g., the meaning of division). If a child doesn't understand how fractions work, it will interfere with his ability to learn algebra later.

Step-by-step explanation:
what is 41% of 100?
hello!
the answer to your question is 41!
-----------
explanation:
- Step 1: Our output value is 100.
- Step 2: We represent the unknown value with [tex]x[/tex].
- Step 3: From step 1 above, [tex]100 = 100%[/tex]%
- Step 4: Similarly, [tex]x = 41%[/tex]%
- Step 5: This results in a pair of simple equations:
[tex]100 = 100% (1)[/tex]% (1)
[tex]x=41[/tex]% (2)
- Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have
[tex]\frac{100}{x}[/tex] = [tex]\frac{100}{41}[/tex]
- Step 7: Again, the reciprocal of both sides gives
[tex]\frac{x}{100}[/tex] = [tex]\frac{41}{100}[/tex]
Therefore, 41% of 100 is 41.
hope this helps! have a great day! :D

Answer:
16 yards gained
Step-by-step explanation:
I would add the yards that were gained first so 14 + 9
so we have 23 yards gained so far then subtract the yards loss so 23 - 7 is 16, so 16 yards were gained.
(please answer if you know how to do this, it's due today !!) Solve for x, y and z. No links please
Answer:
x = 4
y = 2√5
z = 3√5
Step-by-step explanation:
There are 3 right triangles here, so we can create 3 expressions using Pythagoras' Theorem:
a² + b² = c²
(where a and b are the legs, and c is the hypotenuse)
smallest triangle: x² + y² = (x + 2)²
medium triangle: (x + 1)² + y² = z²
largest triangle: (x + 2)² + z² = (x + x + 1)²
rewrite the smallest triangle expression to make y² the subject:
x² + y² = (x + 2)²
⇒ x² + y² = x² + 4x + 4
⇒ y² = 4x + 4
rewrite the medium triangle expression to make z² the subject, substituting y² = 4x + 4:
(x + 1)² + y² = z²
⇒ (x + 1)² + 4x + 4 = z²
⇒ x² + 2x + 1 + 4x + 4 = z²
⇒ z² = x² + 6x + 5
rewrite the largest triangle, substituting z² = x² + 6x + 5 and solve for x:
(x + 2)² + z² = (x + x + 1)²
⇒ (x + 2)² + x² + 6x + 5 = (2x + 1)²
⇒ x² + 4x + 4 + x² + 6x + 5 = 4x² + 4x + 1
⇒ 2x² - 6x - 8 = 0
⇒ x² - 3x - 4 = 0
⇒ (x + 1)(x - 4) = 0
⇒ x = -1, x = 4
as x > 0, x = 4 only
Substitute found value for x into y² = 4x + 4 and solve for y:
y² = (4 x 4) + 4
⇒ y² = 20
⇒ y = √20 = 2√5
Substitute found value for x into z² = x² + 6x + 5 and solve for z:
z² = 4² + (6 x 4) + 5
⇒ z² = 45
⇒ z = √45 = 3√5
Miss K and Mr. T were grading math tests. Miss K grades 9 tests per hour
and has already graded 10. Mr. T grades 7 tests per hour and has already graded 22. After how many hours will they have graded the same amount of tests? How many tests will they have graded?
Step-by-step explanation:
Miss K has already graded 10 tests and is grading 9 every hour. We will add keep adding 9 starting from 10.
Mr. T has already graded 22 tests and is grading 7 per hour. We will keep adding 7 starting from 22.
Miss K: 19, 27, 36. ( Took 3 hours to reach 36 tests)
Mr T: 29, 36. (Took 2 hours to reach 36 tests)
It will take Miss K 3 hours and Mr T 2 hours to have graded the same amount of tests (36).

Can someone help me solve this please
Step-by-step explanation:
Soln
From the above diagram
Height = h = 4cm
Let a&b = upward and downward lengths respectively.
That is:
a = 13cm
b = 16cm
recall that the formula used mathematically in solving/calculating the area of a trapezium is
Area = 1/2×(a+b)×h
Area = 1/2×(13+16)×4
Area = 1/2×(29)×4
Area = (29)×2
Area = 58cm²
I need help fast…………
Answer & step-by-step explanation:
Look at the equation: you can rewrite it as [tex]y= x^2+4x+4 +1 = (x+2)^2+1[/tex]
Now the first term of the sum is at worst 0 (when [tex]x=-2[/tex]) so the sum is no less than 1.
Correct answer is the last option. Graph is the one in the photo, the thin red line is the axis - equation [tex]x=-2[/tex], vertex has coordinate [tex](-2;1)[/tex], Y intersect is [tex](0;5)[/tex] and has no x intercepts. extra points as needed if you want a more accurate graph, mine is sketched on paint so don't expect great quality
What is the rate of change for the line represented by the equation?
x=-4
Answer:
Undefined
Step-by-step explanation:
Given that the equation [tex]x=-4[/tex] is a vertical line that intersects the x-axis at [tex]x=-4[/tex], there is only a change in [tex]y[/tex], but no change in [tex]x[/tex]. Thus, the rate of change is undefined since you cannot divide by 0.
What is the area of the parallelogram
Answer:
24 square units
Step-by-step explanation:
For such questions it is convenient to choose the "base" to be a segment that is aligned with one of the coordinate axes. Here, the horizontal segments will serve. Their length is the difference between the x-coordinates of the end points, -2 -(-6) = 4, for example.
The height is measured perpendicular to the base, so will be the difference between the y-coordinates of the horizontal segments: 2 -(-4) = 6.
The area is given by the formula ...
A = bh
A = 4·6 = 24 . . . square units

helpp !! im helping my friend and i dont know how to do this, 6th grade stuff btw :((
Answer:
81=5+b, 81-5=b, 81-b=5
Step-by-step explanation:
We can write the equation in terms of 81, b, or 5. Let's first start by writing it in terms of 81. We are already given that 5+b=81 therefore...
5+b=81 OR 81=5+b (transitive property)
Now, let's write the equation in terms of b.
5+b=81
Subtract 5 from both sides (subtraction property of equality)
5-5+b=81-5
b=81-5 OR 81-5=b (transitive property)
Lastly, let's write the equation in terms of 5.
5+b=81
Subtract b from both sides (subtraction property of equality)
5+b-b=81-b
5=81-b OR 81-b=5 (transitive property.
Marsha notices that all of her siblings are more than 5 foot 2 inches tall but at most 6 foot 1 inch tall. Write an inequality or pair of inequalities to represent all possible values, in inches, for Marsha’s siblings heights. Graph this set of values on the number line.
Answer:
first make everything inches so you have at least 62 inches and at most 73 inches, now create it.
Step-by-step explanation:
62<x<=73
Answer: 62 < x [tex]\leq[/tex] 73
Step-by-step explanation:
5 feet and 2 inches all in inches would be 62 (12 inches per foot, multiplied by five equals 60, add 2). 6 feet and 1 inch would be 73 inches (12 inches per foot, multiplied by six equals 72, add 1).
Since this inequality has words such as "more than" we have to use # < x. But since at most also applies, we have to use x [tex]\leq[/tex] #.
All her siblings are over 62 inches, so 62 < x. Remember the at most 73 inches, which would be 73 [tex]\geq[/tex] x. We can conclude that the inequalities would be expressed as 62 < x [tex]\leq[/tex] 73.

Derek has a white cube and a red cube.
The numbers 1 to 6 are on the cubes. If
Derek tosses the cubes at the same time,
what is the probability he will get a 4 on
the white cube and a number greater than
4 on the red cube?
Answer:
1/72
Step-by-step explanation:
Probability of getting a 4 on white cube is:
P(W) · P(4) = 1/2 × 1/6 = 1/12
P(R) · P(>4) = 1/2 × 2/6 = 1/6
multiply both probabilities: 1/12 × 1/6 = 1/72

In figure is shown a right circular cone of height 30 cm. A small cone is cut off from the top by a plane parallel to the base. If the volume of the small cone is 1/27 of the volume of given cone, find at what height above the base is the section made.
Answer:
20 cm
Step-by-step explanation:
Think of a large cone, 30 cm high, and a small cone of x height.
The scale factor of a volume of the cube of the scale factor of linear dimensions.
The cubic root of 1/27 is 1/3.
This means that the height of the small cone is 1/3 the height of the large cone.
The large cone has height 30 cm.
The small cone has height 10 cm.
30 cm - 10 cm = 20 cm
Answer: 20 cm
