Question 24
The Sugar Sweet Company is going to transport its sugar to market. It will cost $4500 to rent trucks, and it will cost an additional $250 for each ton of sugar
transported.
Let C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S. Then use this
equation to find the total cost to transport 17 tons of sugar.
Answer: C=250S+4500
C=250(17) + 4500
C=4250+4500
C=8750
Step-by-step explanation:
As an equation, 250 would be the slope because it is multiplying by the ton and 4500 is the y intercept. If you substitute in 17 for S, then multiply 17 by 250, you get 4250 then add the 4500 and you get 8750 so if S=17, C=8750
The cost of transporting 17 tons of sugar is $8750.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
The given information can be related as,
C = 250S + 4500.
Now, when tons of sugar is 17 we'll simply replace S with 17.
∴ C = 250(17) + 4500.
C = 4250 + 4500.
C = 8750.

Adult tickets for a charity concert were $5 each. Students were admitted for $2 each. The charity concert
sold 700 tickets and made $3050. How many students attended the lecture?
Answer:
students 150
adult 550
Step-by-step explanation:
x + y = 700
5x + 2y = 3050
x = 700 - y
5(700 - y) + 2y = 3050
3500 - 5y + 2y = 3050
-3y + 3500 = 3050
-3y = 3050 - 3500
-3y = -450
y = -450 / -3
y = 150
x = 700 - y
x = 700 - 150
x = 550
Solve the following equation 2/3x+6=1/2x+1/4x
Answer:
x = -72/17

Answer:
The answer is
[tex] {p}^{ - m - n} [/tex]Step-by-step explanation:
[tex] \frac{ {p}^{ - m} }{ {p}^{n} } [/tex]Using the rules of indices.
Since the bases are the same and are dividing we subtract the exponents
That's
[tex] \frac{ {x}^{y} }{ {x}^{z} } = {x}^{y - z} [/tex]So from the question we have

I need to answer this using dimensional analysis and the answer must be written in Scientific notation. I can't figure it out.
Answer:
3.343481472 x 10^4
Step-by-step explanation:
11.6 a = 3.25 *
6.18 * = 2.5 #
Take the first equation and solve for *
11.6 a = 3.25 *
Divide each side by 3.25
11.6 a/3.25 = *
3.569230769 a = *
Substitute this into the second equation for *
6.18 (3.569230769 a) = 2.5 #
22.05784615 a = 2.5 #
Solve for a
Divide by 22.05784615
a = 2.5 # / 22.05784615
a = .113338355
We have 2.95 x 10 ^5 a
2.95 x 10 ^5 ( .113338355)

Which function describes this table of values?
Answer:
y = 4/5x
Step-by-step explanation:
We know it's not y = x - 2 because if you plug x into the equation, it works for the first one, but not the second one. Ex: 10 - 2 = 8 but 5 - 2 = 3 not 4.
We also know that it can't be y = -5/4x because if you plug x into that equation, it does not equal y.
y = 4/5x because when you plug x into the equation it works.
TLDR basically you just plug x into the equations.
A dolphin was swimming 28 meters below the ocean's surface. It changed its depth to avoid a predator and ended up 21 meters below the surface.
What was the change in the dolphin's depth?
Answer:
7 meters
Step-by-step explanation:
Now write an equation that represents the situation. You want to find the change in the dolphin's depth, so subtract its beginning depth from its final depth.
The change in the dolphin's depth is negative 7 meters.
What is Subtraction?Subtraction of two or more numbers or algebraic expressions is the method of taking away a certain value from a number. This operation is also called difference of numbers.
Subtraction is one of the basic operations in mathematics along with division, multiplication and addition.
Initial depth that Dolphin was swimming = 28 meters
Then the Dolphin changed it's depth to avoid predator.
Final depth that Dolphin was swimming = 21 meters
Change in depth = Final depth - Initial depth
= 21 - 28
= -7 meters
This implies that depth of the Dolphin decreases with -7 meters.
Hence the change in the Dolphin's depth is -7 meters if the initial depth was 28 meters and final depth was 21 meters.

Point B is on line segment AC. Given AB = 2x + 10, BC = x, and AC = 5x,
determine the numerical length of AC.
Answer:
Step-by-step explanation:
the answer is 25 not 5
The numeric value of x will be 25 for the given line segment.
What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
Given the line segment AC
AC = AB + BC
Given,
AB = 2x + 10, BC = x, and AC = 5x,
So,
5x = 2x + 10 + x
5x = 3x + 10
2x = 10
x = 5
So,
AC = 5x
AC = 5(5) = 25 units.
Hence, The numeric value of x will be 25 for the given line segment.

Which of the following numbers can be classified as a whole number, natural number, integer, and rational number? 0.4. -78 15 0
Answer:
0.4 since the number is non terminating and non repeating therefore it is irrational number.
-78 A rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers. The denominator in a rational number cannot be zero
15 The number 15 is a rational number. It is an integer and all integers are rational numbers.
0 Yes zero is a rational number. Thus, 0 can be written as, where a/b = 0, where a = 0 and b is any non-zero integer.
