Write the
equation.
Slope:
riset
Run
y intercept:
equation: y=mx+b;
Answer: y = 1/4 x – 4
OR y = x/4 –4
m is the slope. b is the y-intercept.
Without numbers on the x and y axis, it may not be correct. But assuming a normal scale, the slope is positive 1/4 and the y-intercept is -4
Step-by-step explanation: To find the slope, m, determine "rise over run"
Look for places where the graphed line crosses the grid at intersections. There seems to be such places at (–4,–5), (0,–4) and (4,–3)
The "rise" is the difference in y-values. Here, they increase by 1.
The "run" is the difference in x-values. Here they increase by 4.
So the slope is 1/4. Put that in place of m.
The graphed line crosses the y-axis at –4
That is the y-intercept. Use -4 in the place of b
Keep the y and x; substitute the values for m and b we found.
y = 1/4 x – 4
OR
y = x/4 – 4 This makes it clear that x is not in the denominator of the fraction, 1/4, and in calculations with given coordinates, the value of x will be divided by 4.

The volume of a sphere is 36 ft. What is the radius of the sphere? Use the formula V = ar to find your
3
answer.
The radius of the sphere is
feet.
Answer:
Radius of sphere = 3 feet
Step-by-step explanation:
The volume of sphere is 36 π ft³.
We need to find the radius of sphere.
The formula used is: [tex]Volume\:of\:sphere=\frac{4}{3}\pi r^3[/tex]
Putting value of volume and finding radius
[tex]Volume\:of\:sphere=\frac{4}{3}\pi r^3\\36\pi =\frac{4}{3}\pi r^3\\r^3=36 \pi \times \frac{3}{4\pi} \\r^3=9 \times 3\\r^3=27\\Taking\:cube\;root\:on \:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{27}\\r=3[/tex]
So, Radius of sphere = 3 feet

Mom buys a rectangular rug with an area of 7 1/6 square meters. The length of the rug is 3 1/3 meters. What is the width of the rug?
Answer:
2 3/20 mStep-by-step explanation:
The area is the product of the length and width
The area = 7 1/6 m² = 43/6 m²The length = 3 1/3 m = 10/3 mWidth = ?
A = lww = A/lw = 43/6 ÷ 10/3 = 43/6 × 3/10 = 43/20 = 2 3/20 mThe width is 2 3/20 m

Step-by-step explanation:
The sum of two numbers is 51 and the greater number is twice the smaller number. Find the numbers. a) set up the variables Let _______ represent the first number Then _______ will represent the second number. b) What is the equation that represents the above situation? c) Solve the equation.
Answer:
34 and 17Step-by-step explanation:
a) set up the variables
Let x represent the first number Then y will represent the second number.
b) What is the equation that represents the above situation?
x = 2yx + y = 51c) Solve the equation.
Substitute x in the second equation and solve for y:
x + y = 512y + y = 513y = 51y = 51/3y = 17Then find x
x = 2y = 2*17 = 34Answer:
[tex]\tt{34~and ~17 }[/tex]
Step-by-step explanation:
let the first number is =x
second number is =y
The sum of two numbers is 51 =x+y=51•••{1}
the greater number is twice the smaller number= x=2y••••••••{2}
According to the question,
[tex]\bold{ x+y=51 }[/tex]
[tex]\bold{2y+y=51 }[/tex] [tex]\because{ (x=2y ) }[/tex]
[tex]\bold{ 3y=51 }[/tex]
[tex]\bold{ y=\dfrac{51}{3} }[/tex]
[tex]\boxed{\blue{y=17 } }[/tex]
NOW put the value y in equation {2}
we get that,
[tex]\bold{ x=2×17 }[/tex]
[tex]\bold{ x=34 }[/tex]
Write an equation of the line that passes (-3,3) and is perpendicular to the line 2y=8x-6
Answer:
2y=8x-30 or -4x+y=-15
Step-by-step explanation:
Answer: y = (-1/4)x + 9/4
Step-by-step explanation:
2y = 8x - 6
So, y = 4x - 3 (Slope = 4)
Slope of perpendicular line = -1/4
Equation of line: y-3 = (-1/4)(x-(-3))
y-3 = (-1/4)x - 3/4
y = (-1/4)x + 9/4

Ratios and unit rates are the same things. True or false?
Answer:
a unit means that we have one of something the unit rate means we have a rate for one or something we write the rate as a ratio with a denominator of 1
so false
Answer:A rate is a comparison of two different quantities with different units, one is generally time. Rates are always ratios, since they are comparing two different numbers as they compare two different quantities. Ratios are sometimes rates, but not always; we can compare different numbers without comparing measurements.

this table shows how many sophomores and juniors attended two school events. what is the probability that a randomly chosen person from this group is a junior? round your answer to two decimal places.
Probabilities are used to determine the chances of an event. Here, we want to calculate the chances of selecting a junior student. The probability of selecting a junior is 0.44.
From the table, we have:
[tex]Junior = 60[/tex]
[tex]Total = 137[/tex]
So, the probability of Junior is
[tex]P(Junior) = \frac{Junior}{Total}[/tex]
This gives:
[tex]P(Junior) = \frac{60}{137}[/tex]
[tex]P(Junior) = 0.437[/tex]
Approximate
[tex]P(Junior) = 0.44[/tex]
Hence, the probability of selecting a junior is 0.44

Question 4 (1 point)
A ball is thrown from a mountain 960 feet high, into the air with an upward velocity of 64 ft/s. When did the ball hit the
ground? And What was the max height it reached?
Answer:
The ball will hit the ground at 10 seconds and its maximum height is 1024 feet.
Step-by-step explanation:
Height of a mountain, h = 90 feet
Upward velocity of a ball, u = 64 ft/s
Its height as a function of time can be written by using the second equation of motion as follows :
[tex]f(x) = -16t^2 + 64t + 960[/tex] .....(1)
When it will hit the ground, f(x) = 0
[tex]-16t^2 + 64t + 960=0\\\\16(-t^2+4t+60)=0\\\\-t^2+4t+60=0[/tex]
It is quadratic equation.
t = -6 s and t = 10 s
Neglecting -6 seconds, the ball will hit the ground at 10 seconds.
For maximum height,
Put f'(x) = 0
[tex]-32t+64=0\\\\\\t=\dfrac{64}{32}\\\\t=2\ s[/tex]
Put t = 2 in equation (1)
[tex]f(2) = -16(2)^2 + 64(2) + 960\\\\=1024\ \text{feet}[/tex]
Hence, the ball will hit the ground at 10 seconds and its maximum height is 1024 feet.

Answer: 16 1/15
23/3+42/5
115/15+126/15
241/15= 16 1/15
I hope this helps:
Answer:
16 1/15
Step-by-step explanation:
Add the whole numbers. 7+8=15
Now, combine the fractions 2/3 and 2/5. To do so, you need a common denominator. The LCD between 3 and 5 is 15.
Whatever you do to one side you must do to the other.
(5/5) 2/3+ 2/5 (3/3)
10/15+6/15=16/15
15+16/15
16/15 is an improper fraction, so convert this fraction to a mixed number.
16/15= 1 1/15
Finally, add the two together. 15+ 1 1/15=
16 1/15
