Katherine uses
7/10
of a gallon of red paint to paint 3/5
of her wall.
How many gallons of red paint will she use to paint her whole wall?
A) 21/50
B)7/15
C) 1 1/6
D) 1 3/10
Answer:
1 1/6 gallons will paint the whole wall
Step-by-step explanation:
7/ 10 gallon paints 3/5 of wall
x gallon will paint 1/1 of wall
7/10 * 1 = x * 3/5
7/10 = 3x/5
3x * 10 = 5 * 7
30x = 35
x = 35/30
x = 7/6 = 1 1/6 gallons
Solve the system by substitution 5x+y=-10. 4x-7y=-8
Answer:
x = -2 and y = 0
Step-by-step explanation:
5x + y = -10
4x - 7y = -8
Rearrange the first equation to equal y.
5x + y = -10
y = -10 - 5x
Replace y in the second equation with the first equation.
4x - 7y = -8
4x - 7(-10 - 5x) = -8
4x - (-70 -35x) = -8
4x + 70 + 35x = -8
Rearrange the equation to find x.
4x + 35x = -8 - 70
39x = -78
x = -2
Now that you know x, use the rearranged first equation to find y.
y = -10 - 5x
y = -10 - 5(-2)
y = -10 + 10
y = 0
2. (i) Find the area of a circle whose circumference
is 52.8 cm
Answer:
A≈8758.26
Step-by-step explanation:
[tex]A\pi r{2}[/tex]=π·52.8[tex]{2}[/tex]
value of pi is approximately 3.14 so
3.14*52.8[tex]{2}[/tex]
≈8758.26
Answer:
[tex]221.8 cm^{2}[/tex]
Step-by-step explanation:
[tex]C=2\pi r\\A=\pi r^{2}[/tex]
[tex]2\pi r=52.8\\r=\frac{52.8}{2\pi }[/tex]
[tex]A=\pi ((\frac{52.8}{2\pi }) ^{2} )[/tex]
[tex]A=\pi (70.61681215)[/tex]

Answer:
I don't see the answer but it is 3/2x - 3 = y
Step-by-step explanation:

The equation of the line representing the graphed function is y = ( 3/ 2 ) x - 3. Option E is correct.
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
The equation is formed by finding the slope using the coordinates ( 0,-3 ),( 2, 0 ) and ( 4, 3 ).
The slope is calculated as,
[tex]m = \dfrac{x_2-x_1}{y_2-y_1}[/tex]
x₁ = 0, y₁ = -3 and x₂ = 2, y₂ = 0.
The equation is given as,
y = mx + c
y = (-3/2)x - 3
Therefore, the equation of the line representing the graphed function is y = ( 3/ 2 ) x - 3.
The complete question is given below;-

Answer:
1.25
Step-by-step explanation:
First we should fill in what we know. They mentioned that the y would be the numerator (# on the top) and the x would be the denominator (# in the bottom).
[tex]\frac{3}{24} =\frac{y}{10}[/tex] <---- This will be your proportion
Now we will cross multiply and make a equation. So we will do 3 * 10 which equals 30 and then 24 * y which is 24y. So now our equation will look like this.
[tex]30=24y\\y=1.25[/tex]
Then when you solve the equation you'll get 1.25

Answer:
The answer is x = 15.
Step-by-step explanation:
To solve this problem, we must first notice that the two angles given are supplementary (their sum adds to 180 degrees).
This lets us create the following equation:
(6x-5) + (6x+5) = 180
We can get rid of the parentheses and simplify the left side of the equation.
6x + 6x - 5 + 5 = 180
12x = 180
To solve for x, we must divide both sides of the equation by 12.
x = 180/12 = 15
Therefore, the correct answer is x = 15.

Activity Warren's tape measure is marked in increments of 16 inch, not in decimal numbers. To measure the tiles, he needs to know the side lengths to to incħ. In this activity, you will convert decimal values to fractional values and then calculate the area of the tiles. the nearest Question 1 Part A The length of tile A is about 2.23607inches, which mark on the tape measure is closest to 2.23607inches? Remember, the tape measure is marked in sixteenths of an inch.
Answer:
the fourth mark after 2 inches
Step-by-step explanation:
each tile measures 2.23607 inches long
That means that the mark will be 2 inches and somewhere in between the third and fourth mark. The third mark is equivalent to 0.1875 inches and the fourth mark is equivalent to 0.25 inches. The mark closest to the actual length of the tile would be the fourth mark after 2 inches.
each mark represents 1 / 16 = 0.0625 inches, if we divide 0.23607 by 0.0625 = 3.69072 marks which we can round to 4 marks
8. Aaron and Zelly want to rent a tandem bike so that
they can ride together. The rental for a tandem bike is
$18.50 per hour plus $3 for each helmet. Aaron and
Zelly have $80 to spend on the bike rental. Which
equation can be used to find h, the number of hours
they can rent a tandem bike? (hint: if you do not know
what a tandem bike is, you need to look it up!)
80 = 6h + 18.50
80 = 18.50h + 3
80 = 18.50h + 6
80 = 3h + 18.50
Answer:
[tex]80 = 18.50h + 6[/tex]
Step-by-step explanation:
Given
[tex]Amount = \$80[/tex]
[tex]Rent = \$18.50[/tex] per hour
[tex]Helmet = \$3.0[/tex]
[tex]Individuals =2[/tex]
Required
Derive an expression for the scenario
A tandem bike allows 2 individuals to ride on it at a time.
So, they will only pay for one rental fee because both can ride on it at the same time.
However, they need to get separate helmets.
For Helmets, they will spend:
[tex]\$3 * 2 =\$ 6[/tex]
For Rental, they will spend
[tex]\$18.50 * h = \$18.50h[/tex] for h hours.
[tex]Total = Rentals + Helmets[/tex]
[tex]Total = 18.50h + 6[/tex]
Recall that they have just $80 to spend
So, substitute 80 for total
[tex]80 = 18.50h + 6[/tex]
Hence, option C answers the question.
Find three consecutive odd integers such that the sum of the first, two times the second, and three times the third is 70
Answer:
9, 11 and 13
Step-by-step explanation:
Let the integers be x, x + 2, x + 4.
x + 2(x + 2) + 3(x + 4) = 70
x + 2x + 4 + 3x + 12 = 70
6x = 54
x = 9
therefore the three integers are 9, 11 and 13

Mariah earns $32.75 per week working as a pet sitter. She worked as a pet sitter for 2 weeks. She previously saved $70.99 in allowance money. She spent $12.25 of her total earning to buy video games. Mariah put 1 over 4 of the remaining money in her savings account. Mariah used the following steps to find the total money she put in her savings account:
Step 1: [($32.75 ⋅ 2) + $70.99 − $12.25] ⋅ 1 over 4
Step 2: [$65.5 + $70.99 − $12.25] ⋅ 1 over 4
Step 3: $136.49 − $3.0625 = $133.4275
In which step did Mariah first make an error? Explain, using words, how Mariah can correct her error.
Answer:
1) Step 3: S = $136.49 - $3.0625 × 1/4
2) By completing the operations within the parenthesis in Step 2, before multiplying the result by 1/4
Step-by-step explanation:
1) From the given information, we have;
The amount amount Maria earns as a pet sitter = $32.75
The number of weeks Maria worked as a pet sitter = 2 weeks
The amount Mariah previously saved = $70.99
The amount Maria spent = $12.25
The amount Mariah put in her savings account = 1/4 of the remaining (balance) money
Therefore, we have;
The amount placed in Mariah's savings account, S, is given as follows;
Step 1: S = [($32.75 × 2) + $70.99 - $12.25] × 1/4
Step 2: S = [($65.5 × 2) + $70.99 - $12.25] × 1/4
Step 3: S = [($136.49) - $12.25] × 1/4
Step 4: S = $124.24 × 1/4
Step 5: S = $31.06
The amount Mariah puts in her saving's account = $31.06 and the step Mariah first makes an error is Step 3 where what she put down was as follows;
Step 3: S = $136.49 - $3.0625 × 1/4
2) She can correct the error by completing the calculation of the operation within the parenthesis in Step 2, before multiplying by the factor 1/4.

use a recursive function for the geometric sequence 2, -6, 18, -54,... to represent the 9th term.
f(9) = f(8) • (-3)
f(9) = f(1) • (-3)^8
f(9) = f(1) + -3(8)
f(9) = f(8) + -3(8)
Answer:
f(9) = f(8)·(-3)
Step-by-step explanation:
A recursive function is one where each successive term is calculated using the previous term;
The clear pattern demonstrated in the sequence of terms shown is that each term is multiplied by -3 to give the next one;
Hence, the correct option is the first.
Answer:
The Answer is A. f(9) = f(8) • (−3)

there is no real answer:
Ok, so a number with all of those characteristics would be 6501, but the last digit can be anything from 1 to 9. a number greater could be anything, so i would choose 6601, and less would be 6401.
The number is 0.056.
The number less than the number 0.056 is 0.0056.
And the number greater than the number 0.056 is 0.56.
What is a place value?Place value, which is related to a digit's location in a number, is the amount that each digit is worth.
A number that has a 6 in the thousandths place, a 5 in the hundredths place, and a 0 in the tenths place.
Let the number is 0.056
And the number greater than the number 0.056 is 0.56.
The number less than the number 0.056 is 0.0056.
Therefore, the numbers are 0.056, 0.56 and 0.0056 in the respective order.
