Answer:
130 grams of 30% sugar and 490 grams of 20% sugar
Step-by-step explanation:
The reason that the answer is what it is is because the total of the sugar syrup must be 600 grams. It is 13% which means that its 1/5 20% and 4/5 10% and if you divide 600 by 5 you get 130 therefore 130 grams of 20% sugar is correct and for the rest just subtract 130 from 610 the get the answer.

Alicia buys a 5-pound bag of rocks for a fish tank. She uses 2 3/8 pounds for a small fish bowl How much is left?
Answer:
2.625 pounds are left or 2 5/8
Step-by-step explanation:
So if your going to be subtracting a fraction from a whole number your going to have to consider the fact that the whole number can be divided up into that fraction.
So in this equation we are subtracting 2 3/8 from 5, we are going to take one from 5 and make it into a fraction so we can subtract:
5 = 4 8/8
Now we subtract 2 3/8 from 4 8/8
4 8/8 - 2 3/8 = 2 5/8
so there's your answer 2 5/8 pounds are left over, but if you wanted the answer in a decimal you would divide 5 by 8:
5/8 = 0.625
you then add 0.625 to 2:
2 + 0.625 = 2.625
And that is also your answer: 2.625 lbs. were left over.
4.32 + b = 19
b = ?
Quick guys my grade are dropping I need help!
Answer:
14.68
Step-by-step explanation:
4.32 + b = 19
Solve for b.
_____________
To solve, we need to get b by itself.
4.32 + b = 19
Subtract 4.32 from both sides :
b = 14.68

Answer : 90%A rancher is going to fence three sides of a corral next to a river. He needs to maximize the corral area using 240 feet of fencing. The quadratic equation A(x)=x(240−2x) gives the area of the corral, A, for the length, x, of the corral along the river. Find the length of the corral along the river that will give the maximum area, and then find the maximum area of the corral.
Answer:
A. 60 feet B. 7200 ft²
Step-by-step explanation:
A. Find the length of the corral along the river that will give the maximum area
To find the length of the corral that will give the maximum area, we differentiate A with respect to x and equate it to zero.
So, dA(x)/dx = d[x(240 - 2x)]/dx
= (240 - 2x)dx/dx + xd(240 -2x)/dx
= 240 - 2x -2x
= 240 - 4x
So, dA(x)/dx = 0
240 - 4x = 0
4x = 240
x = 240/4
x = 60 feet
B. Find the maximum area of the corral
The maximum area at x = 60 feet is
A(x)=x(240−2x)
A(60)=60(240−2(60))
A(60) = 60(240 - 120)
A(60) = 60(120)
A(60) = 7200 ft²
Answer:
maximum: 7200 sq ft. 60 ft along the river
Step-by-step explanation:
The maximum area of 7,200 square feet is reached when the corral has a length of 60 feet along the river.

What expressions are equivalent to y4 - 625?
Answer:
option D
Step-by-step explanation:
a² - b² = (a + b) (a - b)
625 = 5 * 5 * 5 * 5 = 5⁴
y⁴ - 625 = y⁴ - 5⁴
= (y²)² - (5²)² {a = y² ; b = 5²}
= (y² + 5²)(y² - 5²)
= (y² + 25)(y² - 5²)
= (y² + 25)(y + 5)(y - 5)
6(x-6)+4=-32+6x solve please?????
Step-by-step explanation:
first distribute
6x - 36 + 4 = 32 + 6x
combine like terms
6x - 32 = 32+ 6x
subtract 6x from both sides and add 32
0 = 64
therefore no solutions to this problem
Answer:
x = 1/3
Step-by-step explanation:
use the distributive property
6 - 36 + 4 = -32 + 6x
-30 = 4 = -32 + 6x
+32 +32
2 = 4 + 6x
-4 -4
-2 = 6x
divide by 6
x = 1/3
The Capulet's are building a horse stall for their horse, Shaggy. The length, y, of the stall must be more than twice the width, x. However, they only have enough material to build 50 feet of fencing. Write the system of equations or inequalities used to solve it. Identify one option that would meet the criteria.
Answer:
y = 18
x = 7
Step-by-step explanation:
Since the Capulet's only have a total of 50 feet of fencing then that will also be the maximum perimeter of the fence and cannot exceed that value. Therefore, using the information provided we can conclude the following
y > 2x
y + y + x + x <= 50ft
2x + 2x + x + x <= 50ft
Now that we have these equations we can first solve for x and then solve for y
2x + 2x + x + x <= 50ft
6x <= 50ft ... divide by 6
x <= 8.33
y > 2 * 8.33
y > 16.66
Therefore, one possible value would be

factoring trinomials 6n^2-56n-40
Answer:
Step-by-step explanation:
Use the Quadratic Formula to find the roots, i.e., the values of n for which 6n²-56n-40 = 0.
Answer:
2(n - 10)(3n + 2)
Step-by-step explanation:
Given
6n² - 56n - 40 ← factor out 2 from each term
= 2(3n² - 28n - 20) ← factor the quadratic
Consider the factors of the product of the n² term and the constant term which sum to give the coefficient of the n- term.
product = 3 × - 20 = - 60 and sum = - 28
The factors are - 30 and + 2
Use these factors to split the n- term
3n² - 30n + 2n - 20 ( factor the first/second and third/fourth terms )
= 3n(n - 10) + 2(n - 10) ← factor out (n - 10) from each term
= (n - 10)(3n + 2)
Thus
6n² - 56n - 40 = 2(n - 10)(3n + 2)

A new car is purchased for 22300 dollars. The value of the car depreciates at 7.5% per year. To the nearest year, how long will it be until the value of the car is 7700 dollars?
Answer:
13, i think.
Step-by-step explanation:
use the equation: p( 1 - 7.5/100)^r
p= original amount
r = years
sub in numbers
22300 ( 1- 7.5/100)^r
just sub in different numbers for r till you get closest to your answer
After 13 years the value of the car would be $7700
What is an exponential decay?"It describes the decrease in an amount by a consistent percentage rate over a period of time."
What is exponential decay formula?"f(t) = a(1 - r)^t , where t is time, a is the initial value and r is the rate"
For given example,
initial value of the car (a) = 22300
The value of the car depreciates at 7.5% per year.
So, the rate (r) = 7.5%
We can write 7.5 percent as,
7.5% = 7.5/100
= 0.075
So, r = 0.075
Let 't' represents the number of years
We need to find the number of years when the car value is 7700 dollars.
y = $7700
Using the formula of exponential decay,
⇒ y(t) = a × (1 - r)^t
⇒ 7700 = 22300 × (1 - 0.075)^t
⇒ 0.3453 = (0.925)^t
⇒ t = 13.63
⇒ t ≈ 13
Therefore, after 13 years the value of the car would be $7700
