sticks to the plan, how many miles would
he be expected to run during his 8th week

Answer:
25 miles
Step-by-step explanation:
Hakeem is starting a running plan to train for a race. In the first week of his running plan, Hakeem will run 11 miles. The plan calls for Hakeem to increase his weekly milage by 2 miles every week. If Hakeem sticks to the plan, how many miles would he be expected to run during his 8th week of the training plan?
This can be described as:
11 + 2w
when w = week
because he runs 11 miles the first week, he only has 7 weeks of 2 mile increases:
11 + 2(7) = 25 miles
The probability of rolling a six on a bias dice
is 1/5
Work out the probability of rolling exactly
one six
The probability of rolling exactly one six = 0.04
what is probability ?
Probability is a branch of mathematics that deals with the occurrence from of a random event . the value is expressed from zero to one .Probability has been introduced in mathematics to predict how likely events are to happen .
So , acc the question "exactly one six " means that one roll so that probability must be doubled the probability of " not six " is 4/5 . the probability of a 6 on the roll and not on the second is 1/5 x 4/5 =4/ 25 .
The six could come on the second roll so thst probability must be doubled .
the overall probability of exactly one six 8/25 or 0.32
completing toatl probability -no sixes =4/25 x 4/25 =16/25 =0.04
two sixes =1/5x 1/5 =1/25= 0.04
Hence , the probability of rolling exactly one six = 0.04

Jack is building a rectangular fence for his ferret. He has 20 feet of fencing and wants the short side of the fence to be 7
2
feet. How long will the other side of the fence be? Write the answer in decimal form.
The long side will be
feet.
The other side of the fence based on the information illustrated is 6.5 feet.
How to calculate the length?It should be noted that the perimeter of a rectangle is illustrated as:
= 2(length + width)
In this case, the width is given as 7/2 = 3.5 feet.
It should be noted that the perimeter is given as 20 feet.
Therefore, the length will be:
2(length + width) = 30
2(length + 3.5) = 20
2Length + 7 = 20
2L = 20 - 7
2L = 13
L = 13/2
L = 6.5
Therefore, the length is 6.5 feet.

Write the equation of the line that goes through the point (3,-3) and has a slope of -5/3 (in slope intercept form).
The equation of the line that goes through the point (3,-3) and has a slope of -5/3 is y=(-5x+6)/3.
What is a slope?In mathematics, line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent a slope; reason for this is unclear, although it is first used in English by O'Brien in 1844, who wrote the equation for a straight line as "y = mx + b," and by Todhunter in 1888, who wrote it as "y = mx + c."
The ratio of "vertical change" to "horizontal change" between (any) two unique points on a line is used to compute slope. The ratio can also be written as quotient ("rise over run"), which produces same number for every two distinct points on the same line. A declining line has negative "rise." The line might be useful, as determined by road surveyor, or it might appear in a diagram that represents a road or a roof as a description or a design.
The slope's absolute value serves as a gauge for line's steepness, incline, or grade. A steeper line is indicated by slope with a higher absolute value. A line can be drawn with one of four directions: upward, downward, horizontal, or vertical.
if we let y = mx + b, where m is the slope and b is the intercept, and y - y1 = m (x - x1), then:
3(y + 3) = - 5 (X - (-3))
3y + 9 = - 5 X + 15
3y = -5 X + 6
y=(-5x+6)/3
Check:
When x = 3, y should equal - 3, so:
Y = (- 5 (3) + 6)/3 = -3

Supergym is a national chain of gyms. This year, its employees sold 10,412 gym memberships, which turns out to be 52% more than they sold last year. How many memberships did they sell last year?
The supergym sold 15,826.24 membership last year
How to calculate the number of membership sold ?
This year it's employees sold 10,412
This number is 52% more that they sold last year
The first step is to calculate 52% of 10,412
52/100 × 10,412
= 0.52 × 10412
= 5,414.24
The number of membership sold this year can be calculated as follows
= 5414.24 + 10,412
= 15,826.24
Hence the number of membership they sold last year is 15,826.24

1. A man is able to walk 216 feet in 3 minutes. How far can he walk in 1
minute?
Answer: 216/3
Step-by-step explanation:
1 minute / 3 minutes = 1/3
216 feet * 1/3 = 216/3 feet per minute
Answer:
72 feet
Step-by-step explanation:
This question tests on the concept of conversion.
Given from the question, given the man can walk 216 feet in 3 minutes,
3 minutes = 216 feet
(3÷3) minute = (216 ÷ 3) feet
1 minute = 72 feet

What is the value of z in the system shown below?
x+y+z=6
x + 2y = 5
2x+z = 5
========================================================
Explanation:
I'll use the substitution method to solve this system of equations.
Solve the third equation for z
2x+z = 5
z = 5-2x
Then solve the second equation for y
x+2y = 5
2y = 5-x
y = (5-x)/2
y = -0.5x+2.5
Plug each of these into the first equation so we can solve for x.
x+y+z = 6
x+(-0.5x+2.5)+(5-2x) = 6
-1.5x+7.5 = 6
-1.5x = 6-7.5
-1.5x = -1.5
x = (-1.5)/(-1.5)
x = 1
Let's use this to find y and z
y = -0.5x+2.5 = -0.5*1+2.5 = 2
z = 5-2x = 5-2*1 = 3
Therefore,
x = 1
y = 2
z = 3
Or we can write it like this: (x,y,z) = (1,2,3)
-------------------
Check:
Plug these values into equation 1 and simplify
x+y+z = 6
1+2+3 = 6
6 = 6
We get the same thing on both sides.
This confirms equation 1.
Repeat for equation 2.
x+2y = 5
1+2*2 = 5
1+4 = 5
5 = 5
This confirms equation 2.
Lastly, plug those values into equation 3
2x+z = 5
2*1+3 = 5
2+3 = 5
5 = 5
Equation 3 is confirmed.
All three equations are true when (x,y,z) = (1,2,3). The solution is fully confirmed.
