Answer:
50 second
Step-by-step explanation:
let the distance between Michael and kyle (s)
s= 50 m
we want to know how long it takes for Michael(speed 4 m/s ) to reach kyle(3m/s)
v = s/t
t = s/v
Vm = speed of Micheal
Vk = speed of kyle
v = ( Vm - Vk )
t = 50/(4-3) = 50 second
The fuel capacity of a popular hybrid car is 11.9 gallons. The function for this situation is f(x) = -0.02x + 11.9, where x represents miles and f(x) represents the amount of fuel remaining. What is the rate of change for this scenario?
Answer:
-0.02 gallons per mile
Step-by-step explanation:
You're in luck. The fuel consumption of the car is linear, and the slope - ie, the coefficent of the x term gives you the rate of change. In this case, it's -0.02 gallons per mile.

The percentage of a given quantity shows the fraction of the quantity required but expressed in percent. The answer to the question is 8, and Maxine's statement is true.
The percentage of a given number is the fraction of that number required for consideration.
To determine the required fraction of the given number in the question, express the given statement in mathematical terms.
So that:
16% of 50 = [tex]\frac{16}{100}[/tex] x 50
= 0.16 * 50
= 8
Thus 16% of 50 is 8.
Considering the steps required to solve the question and each statement of students, then Maxine is correct.

Step-by-step explanation:
y varies jointly as x and z. If y = 5 when x = 3 and z= 4, find y when x = 6 and z = 8.
Answer:
y = 20
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 5 when x = 3 and z = 4
5 = k × 3 × 4 = 12k ( divide both sides by 12 )
[tex]\frac{5}{12}[/tex] = k
y = [tex]\frac{5}{12}[/tex] xz ← equation of variation
When x = 6 and z = 8 , then
y = [tex]\frac{5}{12}[/tex] × 6 × 8 = [tex]\frac{5}{12}[/tex] × 48 = 5 × 4 = 20

0.25x^2-9
Step-by-step explanation:
Difference of squares converse:
0.25x^2-9
Answer:
0.25x^2-9
Step-by-step explanation:
multiply 0.5x with 0.5x which is 0.25x^2. then multiply 0.5x with 3 which is 1.5x. then multiply -3 with 0.5x which is -1.5x. then multiply -3 with 3 which is 9. so you will have 0.25x^2+1.5x-1.5x-9.
1.5x and -1.5x is 0. so you are left with 0.25x^2-9
432 women attended a conference. Women made up 72% of the total conference attendees.
Men made up the other 28% of attendees.
How many men attended the conference?
Answer:
168
Step-by-step explanation:
If entire number of attendees = y
then number of women = y* (72/100)
since y* (72/100) = 432 ( given)
y =( 432*100)/72
so, y = 600
since men made up the remaining 28% of attendees ,
number of men = y * (28/100) = 600* (28/100)
number of men = 168

Find x if the line through the points (6, x) and (1,-5) has a slope of 2.
Answer:
Step-by-step explanation:
Use the slope formula
m = (y2 - y1)/(x2 - x1)
y2 = x
y1 = -5
x2 = 6
x1 = 1
m = 2
Solution
2 = (x - - 5)/(6 - 1)
2 = (x + 5)/ 5 Multiply both sides of the equation by 5
5*2 = 5(x + 5)/5 Simplify
10 = x + 5 Subtract 5 from both sides
10-5 = x
x = 5

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options.
x2 + (y – 3)2 = 36
x2 + (y – 5)2 = 6
(x – 4)² + y² = 36
(x + 6)² + y² = 144
x2 + (y + 8)2 = 36
Answer:
x2 + (y – 3)2 = 36
x2 + (y + 8)2 = 36
Step-by-step explanation:
The equation that represents circles that have a diameter of 12 units and a center that lies on the y-axis is,
⇒ x² + (y - 3)² = 36
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Since, The standard form for finding the equation of a circle is expressed as;
⇒ (x - a)² + (y - b)² = r²
where;
(a, b) is the center of the circle
And, r is the radius of the circle
Given that;
Diameter = 12 units
And, Radius = 12/2 = 6 units
If the center lies on the y-axis, the center will be at (0, 3)
Substituting into the formula, we will have;
⇒ (x - 0)² + (y - 3)² = 6²
⇒ x² + (y - 3)² = 36
Thus, The equation that represents circles that have a diameter of 12 units and a center that lies on the y-axis is,
⇒ x² + (y - 3)² = 36

What numbers can be used instead to x for this equation to remain the same -x>2
Answer:
2x + 1 = 11.
2x + 1 - 1 = 11 - 1 (subtracting both sides by the same number)
2x = 10.
2x/2 = 10/2 (dividing both sides of the equation by the same number)
x = 5.

Raina's penny bank is 1/4 full. After she adds 360 pennies, it is 5/8 full. How many pennies can Raina's bank hold?
Answer:
960
Step-by-step explanation:
We start with the variable "x". Let's call "x" Raina's penny bank.
After adding 360 pennies, at the end, she has 5/8x, or 5/8.
So we start with
(1/4)x + 360 = 5/8x
Let's subtract 1/4x from both sides
360 = 5/8x - 1/4x
Remember, we need to use common denominators to subtract, so 1/4 becomes 2/8
360 = 5/8x - 2/8x
Now we simplify to get
360=3/8x
Multiply the reciprocal of 3/8 to both sides which is 8/3
360 * 8/3 = x
Answer is 960 pennies.
Therefore Raina's bank hold 960 pennies.
Answer:
we need to get the same number below to make it easier. so 1/4 will be equal to 2/8.
then she adds 360 pennies so it's 5/8 full.
therefore, the 360 pennies = 3/8 full
because 5/8 - 2/8 = 3/8.
now, we need to divide 360/3 so we can get how much pennies when it's 1/8 full.
360 pennies/3 = 120 pennies = 1/8 full.
now to get a full bank we just need to multiply 120 x 8 because 1/8 x 8 = 1 which means a full fraction.
120 pennies x 8 = 960 pennies.
Raina's bank can hold up to 960 pennies.
Write a function that represents the relationship between X and y shown in the graph below
==============================================================
Explanation:
Select any two points from the diagonal line. I'll pick (0,-10) and (2,-4).
Use these points in the slope formula
m = (y2 - y1)/(x2 - x1)
m = (-4 - (-10))/(2 - 0)
m = (-4 + 10)/(2 - 0)
m = 6/2
m = 3
The slope is 3.
The y intercept is b = -10 since this is the location where the diagonal line crosses the vertical y axis.
The values m = 3 and b = -10 have us go from y = mx+b to y = 3x-10
Given: △ABC, m∠A=60°,
m∠C=45°, AB=9
Find: Perimeter of △ABC,
Area of △ABC
Pleas be sure to answer BOTH PARTS ... thank you!
Answer:
p = 32.317
A = 47.911
Step-by-step explanation:
given ∠A = 60
∠C = 45
AB = 9
From sum of all angles in triangle is 180
∠A + ∠B + ∠C = 180
60 + ∠B + 45 = 180
∠B = 180 - 105 = 75
∠B = 75
from sine rule in ΔABC
AB / sin C = BC / sin A
=> 9 / sin 45 = BC / sin 60
=> 9 / 1/[tex]\sqrt{2}[/tex] = BC / [tex]\sqrt{3} / 2[/tex]
=> [tex]9\sqrt{2} = BC * 2 / \sqrt{3}[/tex]
BC = [tex]9\sqrt{2} * \sqrt{3} / 2\\[/tex]
BC = 11.023
length of AC is
AC / sin B = AB / sin C
AC / sin 75 = 9 / sin 45
AC = 9 / 1/[tex]\sqrt{2} * sin 75[/tex]
= [tex]9\sqrt{2} * sin 75\\12.294[/tex]
perimeter of ΔABC
AB + BC + CA
= 9 + 11.023 + 12.294
= 32.317
Area of ΔABC is
= 1/2 * AB * AC * sin A
= 1/2 * 9 * 12.294 * sin 60
= 1/2 * 9 * 12.294 * √3/2
= 47.911
