Answer:
3.88 Pints
Step-by-step explanation:
First we need to find the amount of blue paint that was used. We can do that by multiplying 9.7 by 0.60 since that is 3/5 in decimal form
[tex]9.7*0.60=5.82[/tex]
Now we know how much blue paint was used, now we just need to find how much white paint was used. We can do that by subtracting our amount of blue paint from the total amount of paint used
[tex]9.7-5.82=3.88[/tex]
thus, 3.88 is the amount of white paint used
Can you help me please understand this question
Answer:
D
Step-by-step explanation:
ey/n + k = t
To get y on its own, the first thing we need to do is subtract k from both sides to get ey/n = t - k. Next, we can multiply both sides by n to get ey = n(t - k). Finally, we can divide by e to get y = n(t - k)/e

x = 11.25 and y = 18.75
x = 12.25 and y = 18.75
x = 11.25 and y = 16.45
x = 14.28 and y = 17.95
x = 10.25 and y = 20.75
Answer:
x = 11.25 and y = 18.75
Step-by-step explanation:
ΔABD ≅ ΔBCD
⇒ 20 : 15 = 15 : x
⇒ 20/15 = 15/x
⇒ x = 15 × 15/20
⇒ x = 11.25
⇒ 25 : 20 = y : 15
⇒ 25/20 = y/15
⇒ y = 25/20 × 15
⇒ y = 18.75

How much greater is the surface area of Box A than Box B?
Answer:
Box A is greater than Box B by 34.
Step-by-step explanation:
First, you need to start with finding the surface area of every individual side on Box A we have side A, B, and C. After finding the individual area for each side, double each area because there is two of each side. This is the the same method you apply to Box B.
Then subtract the surface area of Box B from Box A.
4. Randall's monthly water bill from April to July is listed in the table below. What was the percent
increase in his bill from May to July?
Answer:
175
Step-by-step explanation:
Divide. 136.50 divided by 78 then times it by 100 and you get it 175
The percent increase is 56.41%.
what is percent increase?We first calculate the difference between the original value and the new value when comparing a rise in a quantity over time. The relative increase in comparison to the initial value is then determined using this difference, and it is expressed as a percentage. The percentage increase formula is provided by:
percentage increase = (increase in amount /original amount ) x 100
Given:
Bill in may month- 78
Bill in June month = 122
So, change in amount= 122 - 78 = 44
So, percent increase = 44/ 78 x 100
percent increase = 0.5641 x 100
percent increase = 56.41%
Hence, the percent increase is 56.41%.

Using exponential function concepts, it is found that the student error is in the subtraction of the day rate, as he forgot to subtract from 100% = 1.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, the initial value of the computer is of A(0) = 1500, while it decays at a rate of 15% a year, hence r = 0.15 and the equation is:
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]A(t) = 1500(0.85)^t[/tex]
Or equivalently, as a sequence:
[tex]a_n = 1500(0.85)^{n-1}[/tex]
Hence, it is found that the student error is in the subtraction of the day rate, as he forgot to subtract from 100% = 1.

Noa is thinking of two fractions that a sum of 3/5. Each has a numerator of 1. What are the denominators of the fractions
Answer:
The denominators of the fractions are 2 and 10.
The fractions with numerators of 1 that have sum of 3 / 5 is calculated below
The sum of the fractions are 3 / 5. Each of the fractions have a numerator of 1. Therefore, let the denominators be x and y
1 / x + 1 / y = 3 / 5
Therefore,
1 / x + 1 / y = 3 / 5
y + x / xy = 3 / 5
cross multiply
5y + 5x = 3xy
Using hit and trial method,
5(2) + 5(10) = 3(10)(2)

Answer:
y = 2x + 3

Get any two points on the line, say (0, 3) and (2, 7)
Slope = (7 - 3)/(2 - 0) = 4/2 = 2
y = 2x + b
use (0, 3), x = 0, y = 3
3 = b

A company sells each product they make for $90.00. They pay $2,300.00 in monthly costs, such as rent and bills, as well as $75.00 in manufacturing costs per unit. If the company sold 495 units last month, what was their total profit?
A.
$34,825.00
B.
$6,610.00
C.
$42,175.00
D.
$5,125.00
Answer:
Option D
Step-by-step explanation:
Given the following question:
Product costs: $90
Monthly bills: $2,300
Manufacturing costs: $75
How much profit did they make in one month if they sold 495 units?
In order to find the answer, we first need to multiply the cost of the product by the units sold last month, then subtract the bills/manufacturing costs.
One unit = 90 dollars
495 units sold last month
[tex]90\times495=44550[/tex]
[tex]=44550[/tex]
The company made 44,550 from the product last month.
Now apply the fees/costs:
2,300 dollars in monthly costs
75 dollars in manufacturing costs PER UNIT
[tex]44550-2300=42250[/tex]
[tex]75\times495=37125[/tex]
[tex]42250-37125=5125[/tex]
[tex]=5125[/tex]
Which means the company made a total profit of "$5,125 dollars" or option D last month.

It takes 5 minutes for an individual to shower. Of each person showers twice per day, approximately how long does each person spend showering in a year?
Answer:
c
Step-by-step explanation:
Beejjj
Each person spends 2.53 days showering in a year.
What is algebra?Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.
Given that,
Time taken by one person to shower = 5 minutes.
Also, one person take shower 2 times in a day.
Total time taken to shower twice per day = 5 x 2 = 10 minutes.
Since, in one year total number of days = 365.
Time taken to shower in 365 days = 365 x 10 = 3650 minutes.
In one day total number of minutes = 24 x 60 = 1440 minutes.
Total days = 3650 / 1440 = 2.534722 days = 2.53
Person showers for 2.53 days in a year.
