Determine which car gets the better gas mileage (picture below)
Answers
Answer:
Car A
Step-by-step explanation:
All you have to do is find the rate of change
Distance Gallons
300 8
320 10
Car A
300 : 8
37.5 : 1
Car B
320: 10
32 : 1

Answer:
We conclude that the statement 'To host a wedding with 104 people, 13 tables will be needed'.
Hence, option C is correct.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
where 'k' is termed as the 'constant of variation'.
Given that a wedding reception seats 8 people at each table.
Given that the relationship between the number of people 'p' and the number of tables 't'.
p = 8t
CHECKING OPTION A
substitute t = 22 in the given equation
p = 8 × 22 = 176 people
It means to host 176 people, 22 tables will be needed.
Hence, OPTION A is INCORRECT!
CHECKING OPTION B
substitute t = 8 in the given equation
p = 8 × 8 = 64 people
It means to host 64 people, 8 tables will be needed.
Hence, OPTION B is INCORRECT!
CHECKING OPTION C
substitute t = 13 in the given equation
p = 8 × 13 = 104 people
It means to host 104 people, 13 tables will be needed.
Hence, OPTION C is CORRECT!
CHECKING OPTION D
substitute t = 6 in the given equation
p = 8 × 6 = 48 people
It means to host 48 people, 6 tables will be needed.
Hence, OPTION C is INCORRECT!
Thus, we conclude that the statement 'To host a wedding with 104 people, 13 tables will be needed'.
Hence, option C is correct.

Find the x- and y-intercepts of the equation x – 5y = –15. Question 16 options: A) x-intercept: (0,3), y-intercept: (–15,0) B) x-intercept: (0,–15), y-intercept: (3,0) C) x-intercept: (–15,0), y-intercept: (0,3) D) x-intercept: (3,0), y-intercept: (0,–15)
Answers
Answer:
y-intercept: (3,0) C) x-intercept: (–15,0)Step-by-step explanation:
Given the expression x - 5y = -15
x intercept occurs at y = 0
Substituting y = 0 into the expression
x - 5(0) = -15
x - 0 = -15
x = -15
Hence the x-intercept occurs at (-15, 0)
y intercept occurs at x = 0
Substituting x = 0 into the expression
0 - 5y = -15
-5y = -15
y = -15/-5
y = 3
Hence the y-intercept is at (0, 3)
At the gym, Jasper was able to bench press 224 pounds, which was StartFraction 7 over 8 EndFraction of the weight that Balin was able to bench press. Which shows the correct equation and value of x, the weight that Balin could bench press
Answers
Answer:
Balin could bench press 256 pounds.
Step-by-step explanation:
Jasper was able to bench press 224 pounds, which is 7/8 of x, which is the weight that Balin was able to bench press. So, mathematically:
[tex]\frac{7}{8}x = 224[/tex]
[tex]7x = 224*8[/tex]
[tex]x = \frac{224*8}{7} = 256[/tex]
Balin could bench press 256 pounds.

Please Give me brainliest
Answer:
Step-by-step explanation:
the length to the third side can be
a) a^2+b^2=c^2
a=9, b=5
c^2=81+25=106
c=sqrt106=10.29
or
a=5, c=9
b^2=c^2-a^2
b^2=81-25=56
b=sqrt56=7.48
Find the value of x.
Answers
Answer:
x = 18°
Step-by-step explanation:
The sum of interior angles of any polygon is given by:
180(n -2) , where n is the number of sides of that polygon.
So for this pentagon;
The sum of its interior angles = 540°
∴
90 + (9x -6) + (3x + 23) + 95 + (7x - 4) = 540
19x + 198 = 540
19x = 540 - 198 = 342
x = 342 ÷ 19 = 18°

Answer:
The better value is 5pounds for $11
Step-by-step explanation:
2.75×5= $13.75
so the 5 pounds for $11 would be better because the other option would cost $13.75 for the same amount
Answer:
buying the box for $11 is the better option
2.75×5=13.75

Given functions are,
f(x) = 2x - 3
g(x) = x³ - 2
h(x) = x² - 3x + 5
(10). f(4) = 2(4) - 3
= 5
g(-2) = (-2)³ - 2
= -8 - 2
= -10
f(4) + g(-2) = 5 -10 = -5
(11). g(3) = 3³ - 2 = 25
h(1) = 1² - 3(1) + 5
= 1 - 3 + 5
= 3
g(3) - h(1) = 25 - 3 = 22
(12). f(2) = 2(2) - 2 = 2
h(-3) = (-3)² - 3(-3) + 5
= -27 + 9 + 5
= -13
f(2).h(-3) = 2(-13) = -26

Kim paid 3/7 of a bill, Sherri paid 35% of the bill, and Judy paid the rest.
Which of the following statements is true?
a.Kim paid the most.
b.Sherri paid the most.
c.Judy paid the most.
d.They all paid the same amount.
Answers
Since 3/7 is 42.8%
Kim paid 43% of the bill.
Judy paid 22% of the bill.
A - Correct answer.
B - It can't be B because Sherri only paid 35% of the bill.
C - It can't be C because Judy only paid 22% of the bill.
D - It can't be D because Kim and Sherri both paid different amounts.
To work out how much Kim paid, you need to divide 1 by 7 and then multiply that by 3 to get 3/7.
To work out how much Judy paid, you need to add Kim's money together with Sherri's money and take that answer away from 100.

Realistic domain: t >= 0 (as time is non-negative)
When t = 0,
v(0) = -3(0)² + 73(0) + 50 = 50.
Hence Jennifer started with $5000.
Vertex = -b/2a = -(73)/2(-3) = 73/6.
When t = 73/6
v(73/6) = -3(73/6)² + 73(73/6) + 50 = 494.08.
The maximum value is $49,408.

Liz flips a coin 50 times. The coin lands heads up 24 times and tails 26 times. Based on Liz’s results, what is the experimental probability of the coin landing on heads?
Answers
Answer:
48%
Step-by-step explanation:
First, lets start with what we know.
Coin was flipped 50 times. Landed Heads 24 times, and landed tails 26 times.
Now, we want this in a percentage. So:
24 = x
50 = 100
We know that 50 is 100/2. So, we can multiply both of the numbers to get a percentage.
24 × 2 = 48
26 × 2 = 52
In conclusion, the experimental probability for the coin landing on heads is:
48/100 OR 48%

The first term of this geometric series is 5. The common ratio (r) is 3/4. The sum of the infinite series is ...
5(1/(1 -r)) = 5/(1 -3/4) = 5/(1/4) = 20 . . . series sum
Of course, the terms are ...
