a bicyclist covered 5/7 of his route and an additional 40 miles. he has yet to cover 118 miles less than 0.75 of his route. how long is his route
The length of the route of a bicylist that has covered 5/7 of his route and an additional 40 miles and yet to cover 118 miles less than 0.75 of his route is 168 miles.
How to form equation and solve for the variable?The bicyclist covered 5 / 7 of his route and an addditional 40 miles.
Let
x = distance of his route in miles
Hence,
distance covered = 5 / 7 x + 40
He has yet to cover 118 miles less than 0.75 of his route. Therefore,
distance not covered = 0.75x - 118
Distance of his route = 5 / 7 x + 40 + 0.75x - 118
x = 5 / 7 x + 40 + 0.75x - 118
x = 1.464x - 78
x - 1.464x = -78
-0.464x = -78
x = 78 / 0.464
x = 168.103448276
x = 168 miles

Pepe is putting up a fence in his backyard to enclose a garden in form of a triangle. The garden
already has sides enclosed with eight feet and five feet of fence, respectively. What can you say
about the length of the third side?
A
The side needs a fence that is shorter than 8 ft. but not necessarily longer than 5 ft.
The side needs a fence that is longer than 3 ft. and shorter than 13 ft.
C
The side needs exactly 8 ft. of fence.
The side needs exactly 11 ft. of fence.
D
Answer:
We know that in a triangle, given two sides, the third one must be smaller than the sum of the given sides, but greater than their difference:
z < x + y
z > x - y
Therefore, the length of the third side will be between the difference and the sum of the other two sides. In our case:
x + y = 13
x - y = 3
Hence, the correct answer is: B) The side needs a fence that is longer than 3ft. and shorter than 13ft.

Please help and show detailed workings for the answers . Tq
Answer:
Below,
Step-by-step explanation:
(a) f is not defined when x = 2 because this would make the denominator = zero.
(i) f-1 is the inverse of f.
Let y = (x + 1)/(x - 2)
y(x - 2) = x + 1
xy - 2y = x + 1
xy - x = 2y + 1
x(y - 1) = 2y + 1
x = (2y +1)/(y - 1)
Replace x by f-1 and y by x , we get:
f-1 = (2x+ 1)(x - 1)
(ii) f-1 is not defined when x = 1 , as this makes the denominator zero.
A police officer recorded the speeds of the first six cars whose drivers he ticketed for speeding today.
Car Speed
(miles per hour)
1 67
2 74
3 85
4 80
5 74
6 82
What is the mean of the cars' speeds?
Mean is average.
Add the speeds together and divide by number of cars:
67 + 74 + 85 + 80 + 74 + 82 = 462
462/6 = 77
Mean = 77 miles per hour
A packet of vegetable seeds has a germination rate of
90%. What is the probability that exactly 10 of 12
seeds planted will sprout?
N = number of seeds planted
P = probability of germination
K = number that germinated
Using probability calculation:
p(x = k) = (n k) x 0.90^K x 0.10^n-k
p(10) = (12 10) x 0.90^10 x 0.10^2
P(10) = 0.2310
A line has a slope of - 7.
-
(a) What is the slope of the line parallel to it?
(b) What is the slope of the line perpendicular to it?
I need help
Answer:
(a) m = -7
(b) m = 1/7
Step-by-step explanation:
Since parallel lines never overlap, the slopes (m) must be equal. Therefore, a parallel line to a line with a slope of (m = -7) must also have a slope of (m = -7).
Perpendicular lines run opposite of parallel lines. As a result, the sign of the perpendicular slope must be the opposite. Since this slope is negative, the perpendicular slope must be positive. The actual numerical value of a perpendicular slope is equal to one over the slope. Therefore, if a line has a slope of (m = -7), the perpendicular line's slope must be (m = 1/7).
use the rules of significant figures to simplify the following expression: 47.5-6.12
Using the rules of significant figures the expression 47.5-6.12 can be simplified as 41.38.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The number 6.12 has two digits after the decimal while the number 47.5 has only one digit after the decimal therefore, as per the law of significant figures, to deduct 6.12 from 47.5, we need to put one zero at the end of 47.5.
Also, there are two digits in 47.50 before the decimal while 6.12 has only one, therefore, As per the law of significant figures, one zero will be added before 6.12. Thus, the deduction now can be done as,
4 7 . 5 0
- 0 6 . 1 2
4 1 . 3 8
Hence, Using the rules of significant figures the expression 47.5-6.12 can be simplified as 41.38.

There are 2 triangles and 6 circles. What is the simplest ratio of triangles to circles?
Hi!
We are asked to find the ratio.
A ratio is a relationship/comparison between two or more numbers based on their numerical value.
We know that, for every 2 triangles there are 6 circles. We can set up our ratio to look like this:
[tex]\cfrac{2}{6}[/tex]
---
(NOTE: there are many different ways to write ratios, including: "x:y", "x to y", or "x/y")
---
The question asks us to write it in simplest form. The fraction [tex]\cfrac{2}{6}[/tex] is NOT in simplest form. It can be simplified to:
[tex]\cfrac{1}{3}[/tex]
This is the ratio in simplest form.

Find the sum of the first 40 terms of the arithmetic sequence.
14, 4, -6, -16, -26, -36
Answer:
-7240
Step-by-step explanation:
The nth term is -10n + 24.
So the combination of the first and second term would be (-10+24)+(-10x2+24) and this would continue for the first 40 terms so the 24s would add up to 24x40=960. Meanwhile, the -10s would keep adding up so it would be -10-20-30-40.... which you can simplify by making it -10(1+2+3+4) all the way to 40 to make the calculation easier... u can further simplify by making 41 = one pair of numbers so 40+1, 39+2 until you get 21+20 so ur left with -10(20 pairs of 41) so -10(20x41) = -10(820)= -8200.
Add this to your initial 960 so
-8200 +960 = -7240

I don't know what it means by an obtuse angle. I have to choose math because I don't see a subject for shapes and stuff.
Answer:
Angle ADE is an obtuse angle.
Step-by-step explanation:
An obtuse angle is an angle that "opens" greater than 90 degrees. The question asks which angle is an obtuse angle, so basically you follow the order of letters and see which one is greater than 90 degrees (btw, 90 degrees, also known as a right angle, looks like the corner of a square, and anything greater than that is an obtuse angle).
Answer:
An obtuse angle is anything bigger than 90 degrees because 90 degrees is a right angle, therefore D. ADE would be the answer.

The sale price of a backpack is $45.00. This is 75% of the original price.
What was the original price of the backpack?
$33.75
$36.00
$56.25
$60.00
Answer:
$60.00
Step-by-step explanation:
75% OF X (original price) = $45
.75x = $45
divide both sides by .75 to isolate X
.75 / .75 = $45 / .75
X= $60
