Answer:
5/8
Step-by-step explanation:
12/17 is 0.70
5/8 is 0.62
However, 12/17 had a lot more numbers than that so
TRUST ME I GOT EXCEPTED INTO HARVARD
Answer:
12/17 is greater
Step-by-step explanation:
12/17 is greater than 5/8 because to determine which fraction is greater you need to have the same denominator. To get the same denominator I multiplied 17 by 8 and 8 by 17. Since what you do the denominator you have to do the same to the numerator, you would multiply 12 by 8 and 5 by 17 which would lead you to get 12/17= 96/136 and 5/8= 85/136. So, 96/136 > 85/136.
Solve for u 20+17u= -6 + 15u simplify as much as possible.
What it the solution to this equation?
2x+3=x-4
Answer:
x = -7
Step-by-step explanation:
Solve for x:
2 x + 3 = x - 4
Hint: | Move terms with x to the left-hand side.
Subtract x from both sides:
(2 x - x) + 3 = (x - x) - 4
Hint: | Combine like terms in 2 x - x.
2 x - x = x:
x + 3 = (x - x) - 4
Hint: | Look for the difference of two identical terms.
x - x = 0:
x + 3 = -4
Hint: | Isolate terms with x to the left hand side.
Subtract 3 from both sides:
x + (3 - 3) = -3 - 4
Hint: | Look for the difference of two identical terms.
3 - 3 = 0:
x = -3 - 4
Hint: | Evaluate -3 - 4.
-3 - 4 = -7:
Answer: x = -7
You can eat no more than 40 slices of pizza each week. If you have
pizza every day, what is the maximum number of slices (s) you can
eat each day? Round your answer to the nearest tenths place.
i have to create a linear equation and solve it
Answer: 5.7 slices
Step-by-step explanation:
7x=40. x represents number of slices per day, 7 is because you eat pizza every day and there's 7 days in a week.
Divide both sides by 7:
7x/7 = 40/7
x= 5.7

Explicit formula -6,-10,-14
Answer:
Tn = -6 + (n - 1)(-4)
Step-by-step explanation:
The explicit formula is this: Tn = a + (n - 1)*(d), where 'a' is the first term and 'd' is the common difference.
The first term is given to you and that is -6.
The common difference is -4 because:
d = -10 - (-6)
d = -10 + 6
d = -4
Hence: Tn = -6 + (n - 1)(-4)
As the heart beats, blood pressure increases and
decreases. This happens cyclically at the rate of the
person's heart beat. A doctor is monitoring the blood
pressure of a patient whose heart rate is 70 beats per
minute. The maximum blood pressure over the course of
a 10-minute period is 120 mm/Hg and the minimum is 60
mm/Hg.
Find a sine function that models the person’s blood pressure as a function of time (in minutes).
Answer:
A
Step-by-step explanation:
Got it right on edge2020
The sine function that models the person’s blood pressure will be f(x) = 30 sin(Πx/5) + 90.
What is a function?Function is a relationship between two sets X and Y where Set X is called domain and set Y is called codomain.
For example f(x)= sin x+ cos x
We have,
The Blood pressure of patient with the heart rate = 70 beats/ minute
And,
In next 10 minutes,
The maximum blood pressure i.e. (a + d) = 120 mm/Hg
The maximum blood pressure i.e. (-a + d) = 60 mm/Hg
So,
Sine function works on;
f(x) = a sin(bx + c) +d
So,
Now,
Adding Maximum and Minimum blood pressure,
i.e.
(a+d)+(-a+d) = 120 + 60
⇒a + d - a + d = 180
⇒ 2d = 180
d =90
So,
NOw, substituting this value in maximum blood pressure,
i.e. (a + d) = 120
a + 90 =120
a = 30
we have time period = 10 minutes,
So,
2Π/b = 10
⇒ b = Π/5
So,
Count is started at 0.
So, c = 0,
Putting the above value,
f(x) = a sin(bx + c) +d
⇒f(x) = 30 sin(Πx/5 + 0) +90
⇒f(x) = 30 sin(Πx/5) +90
Therefore, the sine function that models the person’s blood pressure as a function of time (in minutes) will be f(x) = 30 sin(Πx/5) + 90.

#30 Tickets to a school play cost $2 if bought in advance and $3 at the door. By selling all 400 tickets, $1,030 was
collected. Let x represent the number of tickets sold at the door.
In terms of x. how many tickets were sold in advance?
Answer:
170 tickets were sold in advance
Step-by-step explanation:
Let x represent the = number of tickets sold at the door.
Let y represent the = number of tickets sold in advance
Tickets to a school play cost $2 if bought in advance and $3 at the door. By selling all 400 tickets, $1,030 was
collected.
Hence, we have two equations
x + y = 400 tickets
$3 × x + $2 × y = $1,030
x + y = 400.... Equation 1
x = 400 - y
3x + 2y = 1030........ Equation 2
Substitute 400 - y for x in Equation 2
3(400 - y) + 2y = 1030
1200 - 3y + 2y = 1030
Collect like terms
-y = 1030 -1200
-y = -170
y = 170
Since y represent the number of tickets sold in advance, therefore, 170 tickets were sold in advance.

Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 10 people took the trip. She was able to purchase coach tickets for $230 and first class tickets for $1290. She used her total budget for airfare for the trip, which was $7600. How many first class tickets did she buy? How many coach tickets did she buy?
You can set up a system of equations for this problem. Let x = number of coach tickets and y = number of first class tickets. Then:
330x + 1220y = 12730 (cost of coach tickets plus cost of first class tickets is total budget)
x + y = 17 (number of coach tickets plus number of first class tickets is total number of people)
Solve the second equation for y to get y = 17 - x, then plug that into the first equation and solve for x:
330x + 1220(17 - x) = 12730
330x + 20740 - 1220x = 12730
-890x + 20740 = 12730
-890x = -8010
x = 9
Sarah bought x = 9 coach tickets. Plug that into the second equation and solve for y:
9 + y = 17
y = 8
Sarah bought y = 8 first class tickets.

Answer:
D. y = 76x
Step-by-step explanation:
First you find the gradient, by using the gradient formula
rise over run
380 - 228
---------------- <- division sign
5 - 3
152/2 = 76
Hence y = 76x + c
Find c by subbing points in. I am going to use this as an example (5, 380)
380 = 76(5) + c
380 -380 = c
c = 0
Hence, y = 76x

Answer:
Choice B) B \sqrt{29} 29 square root of, 29, end square root = √29
Step-by-step explanation:
When given coordinates, the distance between those points(coordinates) is calculated as:
Distance = √(x2 - x1)² +(y2 - y1)²
Given(x1, y1), (x2, y2)
Fromm the question, we are given points(4,7) and (2,2)
Distance = √(x2 - x1)² +(y2 - y1)²
= √(2 - 4)² + (2 - 7)²
= √-2² + -5²
= √4 + 25
= √29
Therefore, Choice B is the answer = √29

if y=24 when x=6, find y when x=-4.
Answer:
[tex]\huge\boxed{y=-16}[/tex]
Step-by-step explanation:
We have to note that this represents a proportional relationship. This means that every time x increases by 1, y will increase by a proportional value.
In order to solve for proportions, we can create a proportion fraction which basically puts two variables over each other. Let's put x over y.
[tex]\frac{x}{y}[/tex]
We know that in the first fraction, x=6 and y=24.
[tex]\frac{6}{24}[/tex]
And we know that x=-4 but we have an unknown y value.
[tex]\frac{-4}{y}[/tex]
We can now set these proportions equal to each other and solve for the missing y using cross products.
[tex]\frac{6}{24}=\frac{-4}{y}[/tex] [tex]y = (24 \cdot -4) \div 6[/tex] [tex]y = -96 \div 6[/tex] [tex]y = -16[/tex]Hope this helped!

Answer:
The correct answer is: The y-intercept is 4
Step-by-step explanation:
A. (correct) explanation-The y-intercept is the point where the line crosses the y-axis (vertical line). The y-intercept here is 4 because that is the point where the line crosses the y-axis
B: The x-intercept is 0 (wrong)
B is wrong because the x-intercept is the point where the line crosses the
x-axis (horizontal line)
C: (wrong) A savings account started with $8 in it
C is wrong because the initial amount is usually the y-intercept, but here the y-intercept is 4.
D: (wrong) It took 4 mins to run a mile
D is wrong because there should have been a point at the location (1,4) for this statement to be true, but there is no point there

Then subtract 180
180 - 130 = 50
Hope that helps
Answer:
50
Step-by-step explanation:
The total degrees is 180 so
use the equation 65+65+x=180
simplify
130+x=180
minus 130 on both sides
x=50
