Answer: 7/10 or 0.7
Step-by-step explanation: 77/10 in decimal form is 7.7. To make 7, you would need to subtract that .7 which would translate to 70/10 after it's subtracted, which is 7.
Answer:
7
Step-by-step explanation:
you need to subtract 7 because 77/10 is 7.7
77-7 is 70. 70/10 is 7
Nora was offered a job that paid a salary of
$
40
,
000
$40,000 in its first year. The salary was set to increase by 3% per year every year. If Nora worked at the job for 21 years, what was the total amount of money earned over the 21 years, to the nearest whole number?
The growth in Nora's salary illustrates a geometric progression
The total amount earned over the 21 years is $1147059
How to determine the total earning?The given parameters are:
Initial salary, a = 40000
Rate, r = 1 + 3% = 1.03
Number of years = 21
The sum of n terms of a geometric progression is represented as:
Sn = a((r^n) - 1)/(r - 1)
So, we have:
S21 = 40000 * ((1.03^21) - 1)/(1.03 - 1)
Evaluate
S21 = 1147059
Hence, the total amount earned is $1147059

Find the solution(s) for x in the equation below.
So
x=4 and x=5Option B
Answer:
B(x=4,x=5)
Step-by-step explanation:
Here,
[tex]x^{2} -9x+20=0[/tex]
We can find the value of x by various methods.
Method 1
By using formula
x=-b±√b²-4ac/2a
For ax²+bx+c=0
Here,
a=1, b=9, c=20
Putting the values.
x=-b±√b²-4ac/2a
x=-(-9)±√9²-4×1×20/2×1
Taking positive one.
[tex]x=\frac{-(-9)+ \sqrt{81-80} }{2} \\\\x=\frac{9+1}{2} \\\\x=5[/tex]
Taking negative one.
[tex]x=\frac{-(-9)- \sqrt{81-80} }{2} \\\\x=\frac{9-1}{2} \\\\x=4[/tex]
x=5,x=4
Method 2
[tex]\hookrightarrow x^{2} -9x+20=0\\\\\hookrightarrow x^{2}-4x-5x+20=0\\\\\hookrightarrow x(x-4)-5(x-4)=0\\\\\hookrightarrow (x-5)(x-4)=0[/tex]
x-5=0....I

What is the slope of the graph of 5x - 2y = 20?
Answer:
slope
5/2
y-inter
-10
The slope of the graph of the equation of the line as 5x - 2y = 20 will be [m] = 5/2
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is the equation of the line as 5x - 2y = 20.
We have the equation of the line as -
5x - 2y = 20
2y = 5x - 20
y = (5/2)x - 10
[m] = 5/2
Therefore, the slope of the graph of the equation of the line as 5x - 2y = 20 will be [m] = 5/2

In a cafeteria 1/10 of the students are eating salads, and, 2/5 are eating sandwiches. there are 20 students in the cafeteria. how many students are eating lunches other than salads or sandwiches
20 x 1/10 have salads = 2 students
and
20 x 2/5 have sandwiches = 8 students
so 10 students are eating lunches other than salads or sandwiches
(20 - 2 - 8)
or 1/10 + 2/5 = 1/10 + 4/10 = 5/10 have salad and sandwich
so 5/10 have no salad no sandwich
and 5/10 x 20 = 10
Answer:
5/10, or 1/2
Step-by-step explanation:
2/5 = 4/10
4/10 + 1/10 = 5/10
10/10 - 5/10 = 5/10

If a person drinks 8 cups of apple juice per month, how many gallons will he drink in one year?
Answer:
2920
Step-by-step explanation:
The gas mileage of two trucks was compared from two different advertisements. The information is shown in the table. If the best gas mileage is the highest rate, which truck has the BEST gas mileage?ATruck A, because for every mile the truck uses 19 gallons. BTruck A, because for every gallon the truck goes 19 miles. CTruck B, because for every mile the truck uses 18 gallons. DTruck B, because for every gallon the truck goes 18 miles
The gas mileage of the trucks is the number of miles traveled per gallon of gas
The truck that has the best gas mileage is (b) Truck A, because for every gallon the truck goes 19 miles.
How to determine the true statementAs stated above, gas mileage measures the miles traveled by one gallon of gas.
This means that options (a) and (c) cannot be true, because these options measure the number of gallons used per mile
From the complete question, truck A uses 1 gallon for 19 miles, while truck B uses 1 gallon for 18 miles.
19 miles per gallon is greater than 19 miles per gallon
This means that truck A has the greater mileage
Hence, option (B) is true

Lewis has to pay $260 more to have his electricity and cable turned on because of his bankruptcy.
What is bankruptcy?Bankruptcy is a legal proceeding involving a person or business that is unable to repay its outstanding debts.
Had Lewis not filed bankruptcy, he would have paid = 90+50+65+75
He would have paid (let us say amount A)= $280
After filing for bankruptcy he has to pay = 205+75+150+110
He has to pay (let us say amount B)= $540
Difference between amount A and amount B = $540-$280
Difference between amount A and amount B = $260
Therefore, Lewis has to pay $260 more to have his electricity and cable turned on because of his bankruptcy.

Do you agree with Diego’s answer?
Is there a different triangle Diego could have drawn that would answer the question? Explain or show your reasoning
The triangle is an equilateral triangle, therefore, Diego didn't draw the right triangle.
What is a triangle?A triangle simply means a polygon that has three edges and vertices. It's a shape in geometry.
In this case, I don't agree with Diego's drawing as the triangle is an equilateral triangle and this means that each side is 60° and not 45° as illustrated.

Four brother each bought two hotdogs and a bag of chips at the football
concession stand. If the bag of chips was $1.25, and the total was $18.20.
what was the price of ONE hotdog?
$1.65
$2.11
$2.27
$3
Answer:
A-$1.65
Step-by-step explanation:
You multiply 1.25 by 4 because each brother bought a bag of chips. Then you subtract that by the total and get $13.20 you divide that by 8 hot dog because each brother got 2 hot dogs. By dividing 8 by the left over amount from subtracting the chips you get how much each hot dog is worth.
