Ross says a $125.95 skateboard at 40% off is cheaper than a $169.95 skateboard at 60% off. Is he correct?
Answers
Answer:
Ross isn't right.
Step-by-step explanation:
Skateboard $125.95 at 40% off is $75.57
How I got the number:
125.95/100 = 1.2595
1.2595 x 40 = 50.38
125.95 - 50.38 = 75.57
Skateboard $169.95 at 60% off is $67.98
169.95/100 = 1.6995
1.6995 x 60 = 101.97
169.95 - 101.97 = 67.98
Therefore the skateboard that is 60% off is cheaper.

a. Y-Int
b. x=0
c. height
d.vertex
Answers
Y is the intercept: for example (0,7) intercept is 7 for y. The y intercept is always x=0 and y=number
x=0 could be a solution or a x intercept.
Height is always the y value in a graph
Vertex is the point at which a parabola changes direction.

Answers
2 2/3 lbs of rice cost $5.52. What is the cost of 1lb
Answers
Answer: I'm not fully sure but I think its 2.07
Answer:
$2.07 per pound
Step-by-step explanation:
we can rewrite 2 2/3 as 8/3
now we can create a proportion from cost to pounds of rice
5.52 is to 8/3 pounds as 'c' is to 1:
(5.52 ÷ 8/3) = c/1
cross-multiply to get:
8/3c = 5.52
multiply each side by 3/8 to get:
c = 5.52(3/8)
c = 2.07

Paul opens a savings account with $350. He saves $150 per month. Assume that he does not withdraw
money or make any additional deposits.
a. Write a linear model that represents the total amount of money Paul deposits into his account after m months.
b. After how many months will Paul have $2,000?
Answers
Answer:
350+150m=total money
11 months
Step-by-step explanation:
you just put in the number of months that have passed in for m and solve for total money.
After how many months will Paul have $2,000?
350+150m=2000
350-350+150m=2000-350
150m=1650
150m/150=1650/150
m=11
The angle of elevation of the sun is 39° from the ground. A business building downtown casts a shadow that is 89 m long. How tall is the building?
Answers
[tex]\tan 39 \textdegree = \displaystyle \frac{h}{89}\\\\89\tan 39 \textdegree = h\\\\h = 72[/tex]Answer:
72 m
Step-by-step explanation:
Hi there!
Using the given information, we can construct a diagram. Please see the attached image.
We need to solve for the height of the building, or the length of the side opposite the angle that measures 39°. Given the only other piece of information is the length of its adjacent side, which is 89 m, we can use the tangent ratio to solve for the height:
[tex]\tan \theta = \displaystyle \frac{opposite}{adjacent}[/tex]
Plug in the given values:
tan 39° = h/89
89 tan 39° = h
h = 72
Therefore, the height of the building is 72 m.
I hope this helps!
Write an equation in slope-intercept form for the line with slope -6 and y-intercept 7. Then graph the line.
Answers
y= -6x + 7
Answer:
y = -6x + 7
Step-by-step explanation:
Slope-intercept form: y = mx + b
where:
m is the slopeb is the y-intercept (when x = 0)Given: a line with a slope of -6, and y-intercept of 7
Equation: y = -6x + 7
y-intercept: (0, 7)Randomly select x-values that will help you graph the equation:
when x = -2:
y = -6(-2) + 7 [multiply]
y = 12 + 7 [add]
y = 19
coordinate: (-2, 19)
when x = 1:
y = -6(1) + 7 [multiply]
y = -6 + 7 [add]
y = 1
coordinate: (1, 1)
when x = 2:
y = -6(2) + 7 [multiply]
y = -12 + 7 [add]
y = -5
coordinate: (2, -5)
These coordinates fall on the line for the linear equation. Graph them on a coordinate plane, and they should give you the line for the equation.

8 A circle passes through the points (0, 2) and (0,8) and its centre lies on the line
x=4.
Draw a sketch and find the equation of the circle.
Answers
Step-by-step explanation:
A circle that passes through point 0,2 and (0,8) and has a center that lies on x=4 is what given.
So we know is center (4,p) for some number p,
Since the points on circumference of the circle have the same x value, then we know that the y coordinate of the center must be the midpoint of the circumferences' y coordinates.
Why?
A circle is not a function since it doesn't pass the vertical line test. And the standard form of a circle is
[tex] {x}^{2} + {y}^{2} = {r}^{2} [/tex]
With center (0,0).
Consider the equation
[tex] {x}^{2} + {y}^{2} = 9[/tex]
The radius is 3 so two points with x coordinate 0 is
(0,3) and (0,-3). And the midpoint of them is (0,0) which is the center. Which is the defining trait of all circles.
Now, back on hand, our the midpoint of 2 and 8 is 5 so our center is
(4,5).
Now, we must find the radius. We use distance formula.
For (4,5) and (0,8).
[tex]d = \sqrt{(8 - 5) {}^{2} + ({0 - 4) {}^{2} } } [/tex]
[tex]d = \sqrt{3 {}^{2} + {4}^{2} } [/tex]
[tex]d = \sqrt{25} [/tex]
[tex]d = 5[/tex]
So our radius is 5.
So now we use the equation of center h,k.
[tex](x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]
H is 4
K is 5
[tex](x - 4) {}^{2} + (y - 5) {}^{2} = 25[/tex]

Answers
Answer:
Yes it is a function. It passes the vertical line test. In other words, it is impossible to draw a single vertical line through more than one point on the V shaped graph. Any input leads to exactly one output.
The domain is the set of all real numbers. This is because we can plug in any x value leading to some specific y value. There are no holes or gaps or jumps to indicate we must restrict any given x value. The domain would not be the set of whole numbers only because values between the whole numbers (eg: decimal values like x = 2.75) work just fine.
The range is the set of y values such that y is either 0 or larger than 0. In short, the range is . Notice how any point on the V shaped graph has a y coordinate that is either 0 or larger than 0. It is impossible to get a y value that is negative.
