Answer:
64 miles
Step-by-step explanation:
If he used 20% of the gas, he can go 20% of the miles
20% of 320 miles
.20 * 320
64 miles
Answer:
[tex]\huge\boxed{\sf 64\ miles}[/tex]
Step-by-step explanation:
A total tank travels to 320 miles
Let the miles be x
He used 20% of the full tank
=> 20% of the full tank = x
=> [tex]\frac{20}{100} * 320 = x[/tex]
=> 2 * 32 = x
=> x = 64 miles
So, He traveled 64 miles in 20% of the tank.

2. Toby Vail.
Annual gross pay of $18,200.
Personal exemptions of $1,500.
State tax on first $3,000: 1.5 percent.
Tax on amount over $3,000:
3 percent.
Answer:
Toby Vail wis taxed for $456
Step-by-step explanation:
First, we make the deductions:
gross pay 18,200 - 1,500 deductions = 16,700 taxable income
Now, we make the tax-calculations:
first $3,000 x 0.015 = $ 45
above:
(16,700 - 3,000) x 0.03 = $411
Total tax levied from the State: $45 + $411 = $456
Notice how the tax is calcualte in brackets to solve for the different taxation rate at different income levels.

If y varies directly as x, and y is 400 when x is r and y is r when x is 4, what is the numeric constant of variation in this
relation?
10
40
100
198
Answer:
10
Step-by-step explanation:
If there is a direct relation between two variables x and y then it can be represented as
y = kx ,
where y is dependent variable
x is independent variable
k is constant of variation
_____________________________
First condition
y = 400
x = r
using y = kx then relationship will be
400 = kr
finding k here
k = 400/r
Second condition
y = r
x = 4
using y = kx then relationship will be
r = 4k
finding k
k = r/4
since in both condition equation is same
thus, value of k will also be same
thus,
400/r = r/4
=> 400*4 = r*r
=> 1600 = r^2
[tex]\sqrt{r^{2} } = \sqrt{1600} \\r = 40[/tex]
Thus, 40 is the value of r
k = r/4 = 40/4 = 10
Thus, constant of variation is 10 which is correct choice.
To cross validate
k = 400/r = 400/40 = 10
Answer:
40
Step-by-step explanation:
[tex]\frac{r}{400}[/tex] = [tex]\frac{4}{r}[/tex]
cross multiply - 400*4 = 1600 and r*r = r^2
square both - √1600 = 40

Mike Is standing on a ladder that is partly in a hole he starts out on a rung that 6 feet underground climbs up 14 feet the climbs down 11 feet what is mikes final position relative to the ground level
Answer:
-3
mike's final position relative to the ground is 3 feet's underground
Step-by-step explanation:
We take positive value when he is above the ground and then take negative value when he is below or underground
6 feet's underground = -6
He climbs up 14 feet = +14
He climbs down 11 feet = -11
We are required to find his last position relative to ground level
= -6+14-11
= (-6) + (-11) + 14
= -17 + 14
= -3
So we have it that mike's final position relative to the ground is 3 feet's underground
When three times the sum of a number and seven is increased by ten, the result is four. What is the number ?
Answer:
x=9 :))
Step-by-step explanation:
First set up your equation.
"3 times" is multiplication
"THE SUM of A NUMBER and seven" that is parenthesis because of the multiplication before it
"is increased by ten" that is an addition at the end
Now we have 3(x+7)+10=4
Solve your equation!
Distribute the 3 now we have 3x+21+10=4
Add like terms
now it should look like this... 3x+31=4
Subtract 31 from both sides and it looks like...
3x=27
Divide by the x-value
x=9
The value of the number will be -9.
What is an expression?
Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that;
The word expression is;
''Three times the sum of a number and seven is increased by ten, the result is four. ''
Now, Let a number be x.
Then, we can formulate the expression as;
3 (x + 7) + 10 = 4
Solve the expression for x as;
3 (x + 7) + 10 = 4
3x + 21 + 10 = 4
3x + 31 = 4
3x = 4 - 31
3x = -27
x = -9
Thus, The value of the number will be -9.

explain how to use a graph of the function f(x) to find f(3)
Answer:
Just find the coordinate at the point where the x-coordinate is 3
Step-by-step explanation:
F(x) is just another term for Y. The variable of X is the value that you input into the f(x), which just stands for a function. Since the value that they asked for was 3, you know that they inputted the value of 3 as x. Just look where the coordinate at the point where the x-coordinate is 3 to find the answer.
Answer:
Sample Response: For f(3), the input is 3 and you are looking for the output. To determine the function's value when x = 3, go to the value of 3 on the x-axis and then locate the graph for that value of x. Determine the value of y from the y-axis at that location on the graph.
