If Leah drove 1,200 miles and used 60 gallons of gas , her average miles per gallon is how much?
Answer:
20
Step-by-step explanation:
We will start by writing the following ratio
miles:gas
1200:60
This means that we have
x:1
divide 1200 by 60 to get x
I get
x=20
Answer:
20 miles per gallon.
Step-by-step explanation:
You have to divide 1,200 by 60. Then you will be left with 20 miles/gallon
Write the quadratic function in standard form
Answer:
B. f(x) = x² + 10x + 17
Step-by-step explanation:
Given:
f(x) = (x + 5)² - 8
Required:
Write in standard form
SOLUTION:
f(x) = (x + 5)² - 8
Expand (x + 5)²
f(x) = (x + 5)(x + 5) - 8
f(x) = x(x + 5) +5(x + 5) - 8
f(x) = x² + 5x + 5x + 25 - 8
Add like terms
f(x) = x² + 10x + 17
Solve the following system by elimination. Show work and explain each step.
3x + 2y=16
2x +5y=21
The value of x and y using the elimination approach on the equations will be 3.45 and 2.81 respectively.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraints.
Given the set of equations,
3x + 2y=16
2x +5y=21
Multiply by 2 to the first equation and by 3 to the second equation.
Fist becomes ⇒
6x + 4y = 32
Second become ⇒
6x + 15y = 63
By subtracting second - first
11y = 31
y = 2.818181...
By substitution,
6x + 4(2.81) = 32
x = 3.454545..
Hence "The value of x and y using the elimination approach on the equations will be 3.45 and 2.81 respectively".

h=l/l-2k make k the subject
Answer:
[tex]k=\dfrac{l(h-1)}{2h}[/tex]
Step-by-step explanation:
The given equation is :
[tex]h=\dfrac{l}{l-2k}[/tex] ....(1)
We need to find the value of k.
Cross multiplying equation (1)
[tex]h(l-2k)=l\\\\hl-2hk=l\\\\hl-l=2hk\\\\k=\dfrac{l(h-1)}{2h}[/tex]
So, the value of k is equal to [tex]\dfrac{l(h-1)}{2h}[/tex].
The heights in inches, of some small trees for sale at a garden store are 62, 62, 59, 61, 59, 70, 59, and 62. What is the median height? What is the mode? What is the mean height?
Answer:
Step-by-step explanation:
the mean height, remember is the average
62+62+59+61+59+70+59+62=494/8=61.75
median is the middle value, so we will write the numbers in order
59,59,59,61,62,62,62,70
we have an even number so we add the middle numbers and divide by 2,
the median=61+62=123/2=61.50
mode is the number that occurs most often : 62 and 59

Write the equation of the line that passes through (9,3) and (7,3)
Answer:
y=3
Step-by-step explanation:
First, let's find the slope (m) of the line, which we do with the equation (y2-y1)/(x2-x1)
the given points are (9,3) and (7,3)
we can label the points:
x1=9
y1=3
x2=7
y2=3
now substitute into the equation
m=(3-3)/(7-9)
m=0/-2
m=0
the slope is 0.
Now, use slope-point form, which is y-y1=m(x-x1)
substitute using the given numbers
y-3=0(x-9)
multiply
y-3=0
add 3 to both sides
y=3
the equation is y=3

A local water storage facility is currently empty. The city
water workers begin filling it at a rate
of 500 gallons per minute. It immediately begins
sending some of its water into the city's water
pipes at a rate of 150 gallons per minute.
a) How much-water will be in the water storage facility
in 25 minutes?
B.) write an equation to find the number of gallons,y,in the storage facility after x minutes.
Answer: See explanation
Step-by-step explanation:
a) How much-water will be in the water storage facility in 25 minutes?
Since the city water workers begin filling it at a rate of 500 gallons per minute, in 25 minutes they'll have filled:
= 500 × 25
= 12500 gallons
It immediately begins sending some of its water into the city's water pipes at a rate of 150 gallons per minutes. In 25 minutes, they'll have sent:
= 150 × 25
= 3750 gallons
Amount that'll be left in the tank will be:
= 12500 - 3750
= 8750 gallons
b. Write an equation to find the number of gallons,y,in the storage facility after x minutes. This will be:
y = (500 × x ) - (150 × x)
y = 500x - 150x
y = 350x

What is fraction?fraction, In arithmetic, a number expressed as a quotient, in which a numerator is divided by a denominator.
In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.
If we divide 1/3 by 2, which is not possible
Fraction also multiplication only.
To make the division into multiplication we have to reciprocal the number on the right side of the division
So,

=1/3*1/2
= 1/6
Hence, 1/3 divided by 2 in fraction form gives 1/6.

I WILL GIVE BRAINLIEST Which of the following tables of x– and y–values represents a function? Select all that apply.
Answer:
A and C
Step-by-step explanation:
For a table of x and y variables to be a function, each x-value must not have two different y-values assigned or related to it. However, different x-values can have the same y-value.
Therefore, the table in option A and option C are functions because every of their x-value has exactly one y-value that corresponds it.

Triangle ABC has side length of 14, 8 and 10.4 what are the possible side lengths of a triangle DEF if ABC is similar to DEF
Answer:
DEF can have possible side lengths of 28, 16, 20.8
Step-by-step explanation:
Triangle Similarity
If the three sides of two triangles have the same proportion, the triangles are similar (SSS theorem).
Triangle ABC has side lengths of 14, 8, and 10.4.
Any other triangle whose side lengths are the same lengths of ABC multiplied by a constant scale factor is similar to ABC.
For example, select scale factor 2. Thus, the triangle of side lengths 2*14=28, 2*8=16, and 2*10.4=20.8 is similar:
DEF can have possible side lengths of 28, 16, 20.8
Any other scale factor will do.

A. True
B. False
True or false:a. If the proportion of defectives in the sample is less than 12%, it is reasonable to conclude that the new process is better.b. If the proportion of defectives in the sample is only slightly less than 12%, the difference could well be due entirely to sampling variation, and it is not reasonable to conclude that the new process is better.c. If the proportion of defectives in the sample is a lot less than 12%, it is very unlikely that the difference is due entirely to sampling variation, so it is reasonable to conclude that the new process is better.
Answer:
false
Step-by-step explanation:
In a population, the percentage or fraction which is not conforming to (defeating) is defined as a ratio of the population's figures of non-conforming goods to the sum of goods in the inhabitants, and the further discussion can be defined as follows:
In option A, it is wrong because the proportion of both the sample is simply an approximation. The real percentage could be more than 12%. Furthermore, the conclusion also that the new procedure is better cannot be reasonably concluded.In options (b and c) both are correct because it is based on the explanation of whether, if the fraction of defective differences is bigger, we can only determine that its new procedure is better or not as a minor difference may occur from the variance of samples.Learn more:

Answer:
98 degrees
Step-by-step explanation:
Since angle LON is a straight angle, that means its measure is 180 degrees. So, the two angles that make up angle LON add up to 180. You can create the following equation:
(3x + 89) + (8x + 58) = 180
Then, add like terms.
3x + 8x = 11x
89 + 58 = 147
11x + 147 = 180
Subtract 147 from both sides.
11x = 180 - 147
Add like terms.
11x = 33
Now, divide by 11 on both sides.
x = 3
Since we now have the value of x, we can plug it into the equation to find angle MON:
MON = 3x + 89
Substitute 3 for x
MON = 3(3) + 89
MON = 9 + 89
MON = 98
