13. The sum of twice a number and four
14. The quotient of a number and three
15. A number divided by eleven
Answer:
You have to translate these sentences into expressions. I am not going to solve all of these because if I explain one/two problems to you, you'll get the hang of it. Seven more than three times a number: 7+3x; Five times a number decreased by six: 5x-6
Step-by-step explanation:
Why? We don't know what number that is, so we can put any variable like (x, y, z, a, b, etc.). Three times a number is simply that number times 3. In this case we would input: 3*x, or 3x. 7 more than that number is 3x+7. Five times a number decreased by six: 5x-6 . Remember: it is simply 5*x which simplifies to 5x. Decreased is take away, so take away 6, and get 5x-6
Key words: Quotient: the result after dividing two/or more numbers; Product: the result after multiplying two/ or more numbers; Decreased: take away (Example: x decreased by 7=x-7)
I hope you understand!! It is very simple after you start to get the hang of it!!
kelsey purchases a coupon book with discounts for her favorite coffee shop: every coupon for the coffee shop offers the same discount. The table shows her total savings, y, based on the number of coupons, x, used from the book. what are the slope and Y intercept of the line represented by the points shown in the table?
9514 1404 393
Answer:
b. slope: 2; y-intercept: -20
Step-by-step explanation:
The y-intercept is the first point in the table, where x=0. That eliminates choices A and D.
The slope is the difference in y divided by the difference in x. Using the first and second points in the table, this is ...
(-10 -(-20))/(5 -0) = 10/5 = 2
The slope is 2; the y-intercept is -20.

Answer:
I think the answer is corresponding angles postulate because they are intersected by a transversal and are equal and are parallel lines.
in the figure, m<2 = 56. What is the measure of <1?
Answer:
Well, we know that the interior angles of any triangle add up to 180. We also know that a pair of supplementary angles adds up to 180. Furthermore we know that the figure in an iscoceles triangle. We know this since the 2 lines of the triangle are marked with a bisecting arc indidcating that they are equal in length. Therefore the 2 base angles are equal by the rules of an isosceles triangle. Let M and N represent the 2 base angles:
by using the rule that the interior angles add up to 180 we see that 56 +m +n=180
M and n are the same values since this is an isosceles triangle.
56 +m +n=180
m+n=124
Since m and n are the same values we just divide 124 by2
m, n=62
Therefore by using the rules of supplementary angles if the base angles equal 62 then the m<1 and 62 should add up to 180 since suplementary angles add up to 180. 180-62=118
m<1=118

can someone help me understand ratios
Answer:
Step-by-step explanation:
A ratio says how much of one thing there is compared to another thing.
ratio 3:1
There are 3 blue squares to 1 yellow square
Ratios can be shown in different ways:
Use the ":" to separate the values: 3 : 1
Or we can use the word "to": 3 to 1
Or write it like a fraction: 31
A ratio can be scaled up:
ratio 3:1 is also 6:2
Here the ratio is also 3 blue squares to 1 yellow square,
even though there are more squares.
Credits to math is fun
ratios compare two quantities
basically ratios are usually in the form x : y (x to y), where the quantity of x is compared to the quantity of y. there can be different values for x and y in this case. they can either both be part of a whole, or one can be part of a whole while the other is the whole.

Which of the following are the most likely factors of the function graphed above?
A. (x-3)(x+4)
B. (x+3)(x-4)
C. (x+2)(x-4)
D. (x)(x+12)
Answer:
Option (B)
Step-by-step explanation:
From the graph attached,
x-intercepts of the graphed function are,
x = -3 and x = 4
Therefore, zero factors of the function will be,
(x + 3) and (x - 4)
So the quadratic function given in the graph will be in the form of,
f(x) = (x + 3)(x - 4)
Option (B) will be the correct option.
Select all names that apply.

If you buy 1 ticket in canada's lotto 6/49 lottery game, the probability that you will win a prize is 0.15. Given the nature of lotteries, the probability of winning is independent from month to month. If you buy 1 ticket each month for five months, what is the probability that you will win at least one prize?
Answer:
0.5563
Step-by-step explanation:
Given that :
Probability of winning (p) = 0.15
Number of months = number of trials (n) = 5
1 - p = 1 - 0.15 = 0.85
Probability of winning atleast one price ;
P(x = x) = nCx * p^x * (1 - p)^(n-x)
P(x≥1) = p(1) + p(2) + p(3) + p(4) + p(5)
Using the binomial probability calculator to save computation time :
P(x≥1) = 0.556294
P(x≥1) = 0.5563
Probabilities are used to determine the chances of events.
The probability that you win at least one prize is 0.5563
The given parameters are:
[tex]p = 0.15[/tex] --- the probability of winning
The probability of losing (q) is then calculated using the following complement rule
[tex]q= 1 - p[/tex]
[tex]q= 1 - 0.15[/tex]
[tex]q= 0.85[/tex]
The probability that you win at least one prize is the complement of not winning at all.
So, we have:
[tex]P(At\ least\ 1) = 1 - P(None)[/tex]
This gives
[tex]P(At\ least\ 1) = 1 - 0.85^5[/tex]
[tex]P(At\ least\ 1) = 1 - 0.4437[/tex]
Evaluate like terms
[tex]P(At\ least\ 1) = 0.5563[/tex]
Hence, the probability of winning at least one prize is 0.5563

Laurie was scuba diving. Each time she dove 5 feet deeper, she would stop and clear her ears. After Laurie had checked her instruments 3 times, she was at her maximum depth of 60 feet. Which expression best represents Laurie's maximum depth? (4) (negative 5) (3) (Negative 4) (Negative 5) (Negative 3) (Negative 5) (20) (3) (Negative 5) (Negative 20) (Negative 3)
Complete question :
Answer:
(-5) * (20) * (3)
Step-by-step explanation:
Diving 5 feets deeper = descent = negative 5 Feets
Each time instrument is checked = (60/3) = depth of 20 feets
Number of times instrument is checked = 3
Hence, maximum depth :
Diving 5 feets deeper * Each time instrument is checked = depth of 20 feets * Number of times instrument is checked
(-5) * (20) * (3) = - 60

Setup a rational equation and solve it from the word problem. Mr. Solberg can ride his scooter 3 miles against the wind in the same time it takes him to scooter 4 miles with the wind. If the speed of the wind is 5 mile per hour, how fast does Mr. Solberg scooter when there is no wind?
Answer:
The speed of Mr Solberg's scooter when there is no wind is 35 miles per hour
Step-by-step explanation:
The given parameters are;
The time Mr. Solberg rides his scooter and cover 3 miles against the wind = The time Mr. Solberg rides his scooter and cover 4 miles with the wind
The speed of the wind = 5 miles per hour
Let v, represent the speed of Mr Solberg's scooter when there is no wind, we have;
Time = Distance/Speed
Mr Solberg's speed against the wind = v - 5
Mr Solberg's speed with the wind = v + 5
The distance covered at a given time, while riding against the wind = 3 miles
The distance covered at the same time, while riding with the wind = 4 miles
The time in both instances are therefore 3/(v - 5) = 4/(v + 5)
From which we have;
3 × (v + 5) = 4 × (v - 5)
3·v + 15 = 4·v - 20
20 + 15 = 4·v - 3·v
4·v - 3·v = 20 + 15
v = 35
The speed of Mr Solberg's scooter when there is no wind = v = 35 miles per hour.

Triangle P R Q is shown. The length of side P R is 5 n. The length of side R Q is 32 + n. Angles R P Q and P Q R are congruent. What is the length of PR?
Answer:
20Step-by-step explanation:
According to Triangle P R Q, if angles R P Q and P Q R are congruent, this means that two of the sides of the triangle a re also congruent (Isosceles triangle).
We can say then that length of side PR is equal to that of RQ i.e PR = RQ
Given
PR = 5n
RQ = 32+n
Required
Length of PR
Since the two sides are equal i.e PR = RQ
5n = 32+n
5n - n = 32
4n = 32
n = 32/8
n = 4
Get PR;
Since PR = 5n
PR = 5(4)
PR = 20
Hence the length of PR is 20.

40

Use absolute value to express the distance between 8 and -5
Answer:
The distance between points 8 and -5 is 13
Step-by-step explanation:
We need to find distance between points 8 and -5
The formula used to find the distance is: [tex]Distance=|b-a|[/tex]
Absolute value is used to get only positive values. i.e |-1|=1 if required.
We are given: b=8 and a=-5
Putting values and finding distance
[tex]Distance=|b-a|\\Distance=|8-(-5)|\\Distance=|8+5|\\Dstance=|13|\\Distance=13[/tex]
So, the distance between points 8 and -5 is 13
