Answer:
a. $35
b.$21
Step-by-step explanation:
a. It is what your are multiplying the number of lawns mowed by
b. -2y = -42
divide by -2 on each side
y=21

tomatoes are $2.75 per pound, or you can buy a 5 pound box for $11. what is the better value option?
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
so 5 pounds separately would be $13.75

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
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.

Find the value of x.
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:
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.

Two side length of a triangle are given as 9 cm and 5 cm. What could be the length of its third side?
Answer: Two sides are given 5 cm and 9 cm. .Therefore, the third side can not be greater than or equal to (9+5)=14 cm and it can not be less than or equal to (9–5)=4 cm
Step-by-step explanation:
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

Answer:
(c) 5 +15/4 +45/16 +135/64 +...; 20
Step-by-step explanation:
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 ...
5 + 5(3/4) +5(3/4)² + 5(3/4)³ + ...
= 5 + 15/4 + 45/16 +135/64 + ... . . . series
Together, these observations match choice C.

Answer:
Step-by-step explanation:
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

When taking the sine and cosine of different angles in your calculator, why are they sometimes the same? Why do they sometimes produce the same answer? ex: sin 55* = 0.819152044 and cos35* = 0.819152044 or sine 30* and cos 60*
Answer:
sin(theta) = 90 - cos(theta)
cos(theta) = 90 - sin(theta)
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?
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 new price of the TV after a 20% decrease is $319.20
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)
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)
