Answer:
11/40
Step-by-step explanation:
If your answering in fraction and not in decimal this is how you do it:
1. Get rid of the brackets surrounding -11/10. You do this by multiplying the positive sign (+) by the negative sign (-) in front of 11. Now the rule says that multiplying a positive with a negative always gives you a negative therefore your fraction in the brackets will remain negative while removing the plus sign. Now your problem should look like this: 11/8-11/10.
2. Finding the common multiple of the denominators. You can't just minus the fractions unless the denominators are the same. To do this you first have to find the lowest common multiple (lcm) of denominators 8 and 10. You can list 5 multiples for each to find this or more depending on how many multiples you need to reach the lcm.
8= 8,16,24,32,40,48,etc.
10=10,20,30,40,50,etc.
The lcm for 8 and 10 is 40.
3. Change the fractions to substitute the new value of the denominators in. To do this you have to multiply the fractions. For example, multiply 11/8 by 5/5 to get 55/40(11×5/8×5). Do the same for the second fraction: 11/10×4/4(11×4/10×4) which gives 44/40.
4. Now finally just minus which is just 55/40-44/40 and your answer will be 11/40. Minus the numerators only not the denominators.

Answer:
A. 5y = 45.00; y = 9.00
Step-by-step explanation:
Step 1:
There are 5 friends in total and since we don't know how much money each of them contributed to the total amount ($45.00), we will substitute it with the variable y.
So, the amount of money the friends contributed is 5y.
The total amount of all the friends' money put together is given; $45.00.
So 5y = 45.00
______________
Step 2:
Divide 45.00 by 5 to find out how much each of the five friends contributed individually;
45.00 ÷ 5 = 9.00
So the amount of money the each friend contributes individually/ have to spend to buy a present for her individually is $9.00.
y = 9.00
______________
Model it:
5y = 45.00; y = 9.00
______________

what is the difference between a categorical and continuous variable?
Answer:
In a categorical variable, the value is limited and usually based on a particular finite group. For example, a categorical variable can be countries, year, gender, occupation. A continuous variable, however, can take any values, from integer to decimal.

given m || n, calculate the value of x
Answer: x = 41
Step-by-step explanation:
4x - 68 = 2x + 14 [since alternate interior angles are equal]
4x - 2x = 14 + 68
2x = 82
x = 41
Answer:
x=41
Step-by-step explanation:
this problem can be solved using the alternate interior angles converse theorem, which states that if two coplanar lines are cut by a transversal so that a pair of alternate inerior angles are congruent, then the two lines are parallel.
4x-68=2x+14
2x-68=14 <- subtract 2x from both sides
2x=82 <- add 68 to both sides
x=41 <- divide both sides by 2
check:
4(41)-68=96
2(41)+14=96
w + 2x + 1 = x – 2w +26
If you know two angle measures of a triangle in spherical geometry, can you always find the measure of the third angle? Explain.
A. Yes; the angle measures of a triangle always sum to 180.
B. Yes; the angle measures of a triangle always sum to 270 in spherical
geometry.
C. No; the sum of angle measures in spherical geometry is always greater than
180, but there is not a particular number they must sum to.
D. No; the sum of angle measures in spherical geometry is always greater than
270, but there is not a particular number they must sum to.
When two angle measure of a triangle are given in spherical geometry: The sum of angle measures in spherical geometry is always greater than 180, but there is not a particular number they must sum to. Choice C (No) is correct
According to the question;
Two angle measures of a triangle in spherical geometry are given.However, unlike in plane geometry where affirmatively, the sum of angles in a triangle is equal to 180°.
In spherical geometry;
The totality of the angles of a triangle on a sphere is given as 180°(1 + 4x), where x is the fraction of the sphere's surface that is enclosed by the triangle. For any positive value of x, which in each case exceeds 180°.

A car rental agency charges $75 per day, which includes 100 miles. For each mile over 100 miles, there is an additional cost of $0.35 per mile. Write an equation relating
m, the number of miles driven, if the total cost for a one-day rental was $131.
Part A. Write an equation relating m , the number of miles driven, if the total cost for a one-day rental was $131.
Part B. Find the solution to the equation you created in the previous question and explain what the solution means in this situation.
The number of miles, m driven if the total cost for a one-day rental was $131 is; m = 160
According to the question;
The agency charges $75 per day, which includes 100 miles.Additionally, the agency charges $0.35 per mile for each additional mile;a) The equation relating m , the number of miles driven, if the total cost for a one-day rental was $131 is therefore;
$0.35m + $75 = $131.b) To find the solution to the equation;
$0.35m = $131 - $75$0.35m = $56m = $56/$0.35m = 160.
The number of miles, m driven if the total cost for a one-day rental was $131 is; m = 160.

See belowStep-by-step explanation:
Given numbers:

We know the numbers increase from left to right on the number line, so the numbers to the left are smaller than the numbers to the right.

Answer:
-150
Step-by-step explanation:
this is because you do 250 - 100 which equals -150
In part A you subtracted 100 from 100 giving you 0.
Continuing to part B you would subtract 100 from 250 leaving you with 150.

find the width of radius r if the width w of the shaded region is 2cm and its area is 176cm^2, use 22/7 for pi (its a full circle)
The area of a shape is the amount of space it can occupy.
The value of r is 13
From the question (see attachment), we have:
[tex]\mathbf{A =176}[/tex] --- area of the shaded region
[tex]\mathbf{w = 2}[/tex] --- the width of the shaded region
The area of the complete circle would be:
[tex]\mathbf{A_1 =\pi (r + w)^2}[/tex]
The area of the small circle is:
[tex]\mathbf{A_2 =\pi r^2}[/tex]
So, the area of the shaded region is:
[tex]\mathbf{A = A_1 - A_2}[/tex]
Substitute known values
[tex]\mathbf{176 =\pi (r + w)^2 - \pi r^2 }[/tex]
Substitute 2 for w
[tex]\mathbf{176 =\pi (r + 2)^2 - \pi r^2 }[/tex]
Expand
[tex]\mathbf{176 =\pi (r^2 + 4r + 4) - \pi r^2 }[/tex]
Open brackets
[tex]\mathbf{176 =\pi r^2 + 4\pi r + 4\pi - \pi r^2 }[/tex]
Cancel out line terms
[tex]\mathbf{176 =4\pi r + 4\pi }[/tex]
Divide through by 4
[tex]\mathbf{44 =\pi r + \pi }[/tex]
Factor out pi
[tex]\mathbf{44 =\pi(r+ 1) }[/tex]
Divide through by pi
[tex]\mathbf{r + 1= \frac{44}{ \pi} }[/tex]
Substitute 22/7 for pi
[tex]\mathbf{r + 1= \frac{44}{ 22/7} }[/tex]
Using a calculator, we have
[tex]\mathbf{r + 1= 14}[/tex]
Solve for r
[tex]\mathbf{r= 14 -1}[/tex]
[tex]\mathbf{r= 13}[/tex]
Hence, the value of r is 13

In 2010, the population of a city was 168,000. From 2010 to 2015, the population grew by 7%. From 2015 to 2020, it fell by 6%. How much did the population decrease from 2015 to 2020, to the nearest 100 people?
Answer:
169,000 people
Step-by-step explanation:
increase from 2010-2015:
168000/100 = 1680 = 1%
1680 x 7 = 11,760 people
population at 2015 = 168000+11760 = 179,760
decrease from 2015-2020:
179760/100 = 1797.6 = 1%
1797.6 x 6 = 10,785.6 people
population at 2020 = 179760-10787.6 = 168,974.4 people
rounded to the nearest 100 = 169,000 people
