Please use the math box to show any additional work.
I dont know
3.5 cup mix & 2.625 cups water
2625 cups mix & 3.5 cup water
28 cups mix & 21 cups water
21 cups mix & 28 cups water
Submit and Explain
Answer:
It takes 3.5 cups of pancake mix and 2.625 cups of water to make 21 pancakes.
Step-by-step explain
First divide each by 6 to figure out how much mix and water it takes to make one pancake
1/6 mix + .125 cups water = 1 pancake
Multiple each by 21 to know how much mix and water it takes to make 21 pancakes
3.5 mix + 2.625 water = 21 pancakes
Answer:
15 3/4
Step-by-step explanation:
you multiply 3/4 times 21 then you will get 3/4 times 21/1 and the answer is 63/4 and simplify and get 15 and 3/4.
-7m²-10m+17
common factor
Answer:
Greatest common factor of 17
So, the prime factors of 45 are 3, 3, and 5. The Greatest Common Factor is the greatest number that is common (that is, in both lists). It is 17. Since 17 is a factor of itself and of 51 -- which is 3 x 17 -- then the greatest possible common factor is 17!
Step-by-step explanation:
Add and subtract the second term to the expression and factor by grouping.
- (m - 1 )( 7m + 17 )
Tom made fruit punch for a party. He mixed 2 gallons of orange juice, 4 quarts of pineapple juice, 3 pints of cranberry juice, and 8 cups of apple juice. How many quarts did he make in all? (2 points)
Answer:
15.5 quarts
Step-by-step explanation:
1.5 +8 + 4 + 2
there is need to convert the measures that are not in quarts to quarts
1 gallon = 4 quarts : 2 x 4 = 8 quarts
1 cup = 0.25 quarts : 0,25 x 8 = 2 quarts
1 pint = 0.5 quarts : 0.5 x 3 = 1.5 quarts
Total quarts = 1.5 +8 + 4 + 2 = 15.5 quarts

could you work out this question please ?
Answer:
R = 30
Step-by-step explanation:
Given y is directly proportional to R² then the equation relating them is
y = kR² ← k is the constant of proportion
To find k use the condition when R = 4, y = 24, then
24 = k × 4² = 16k ( divide both sides by 16 )
1.5 = k
y = 1.5R² ← equation of proportion
When y = 1350 , then
1350 = 1.5R² ( divide both sides by 1.5 )
900 = R² ( take the square root of both sides )
[tex]\sqrt{900}[/tex] = R , that is
R = 30
2500 dollars is placed in an account with an annual interest rate of 7.25%. To the nearest year, how long will it take for the account value to reach 13100 dollars?
please help!^^
Answer:
about 58 years 6 months
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 7.25%/100 = 0.0725 per year,
then, solving our equation
t = 10600 / ( 2500 × 0.0725 ) = 58.4828
t = 58.4828 years
The time required to
accumulate simple interest of $ 10,600.00
from a principal of $ 2,500.00
at an interest rate of 7.25% per year
is 58.4828 years (about 58 years 6 months).
Answer:
5 years
Step-by-step explanation:
Find out how much you earn a year from interest and money.
Find 1%.
100% = 2500
1% = 2500 ÷ 100 = 25
7.25% = 25 x 7.25 = 181.25
2500 + 181.25 = 2681.25
Now divide how much you earn from money and interest from 13100.
13100 ÷ 2681.25 = 4.88
4.88 estimated to 5

Alex paid 108.34 for groceries. Rounded to the nearest dollar, how did alex pay for groceries?
The rounded figure of the amount Alex paid at the groceries shop is $108.
What is rounding a figure?The process of replacing a number by another number of approximately the same value but having fewer digits is called rounding a figure.
Given that, Alex paid 108.34 for groceries. We need to round it to the nearest dollar,
We know that,
If the first decimal digit is 5 or more, we increase the whole part by one unit. For example, $34.57 rounded to the nearest whole dollar is $35.
If the first decimal digit is less than 5, we leave the whole part as it is. For example, $45.19 rounded to the nearest dollar is $45.
Here, the first decimal point is less than 5, therefore, we will leave the whole part as it is.
Hence, the rounded figure of the amount Alex paid at the groceries shop is $108.

Answer:
y = 1/2 x+4
Step-by-step explanation:
Slope intercept form is y = mx+b, where m equals the slope and b is the y-intercept.
The slope can be calculated using the formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex].
I'll be plugging in (2,5) and (4,6) to calculate the slope.
m = (6-5)/(4-2) = 1/2
The y-intercept is the y-coordinate of where the line meets the y-axis. In the graph, you can see that the line intersects with the y-axis at (0,4). The y-coordinate of (0,4) is 4, so therefore it is the y-intercept.
Plugin m = 1/2 and b = 4 into the slope-intercept formula (y = mx+b), and you get y = 1/2 x+4
