A recipe of chicken marinade says mix 3 parts with oil with 2 parts soy sauce and 1 part orange juice if you need 42 cups of marinade in all how much of each ingredient should you use
Answers
Answer:
21 cups oil
14 cups soy sauce
7 cups orange juice
Step-by-step explanation:
Use 1 cup for 1 part. The original recipe as given with its small amounts would make a total of 3 + 2 + 1 = 6 parts, or 6 cups of sauce.
You want to make 42 cups.
42/6 = 7
The amount you want to make is 7 times the amounts in the ratio.
3 parts oil: 3 × 7 = 21: 21 cups oil
2 parts soy sauce: 2 × 7 = 14: 14 cups soy sauce
1 part orange juice: 1 × 7 = 7: 7 cups orange juice
Check: 21 + 14 + 7 = 42
The amounts above do make 42 cups in total.

−3.48; The line of best fit overpredicts the temperature change.
3.48; The line of best fit underpredicts the temperature change.
Answers
residual = 3.48
The line of best fit underpredicts the temperature change.
============================================================
Explanation:
If s = 1.3, then ŷ is...
ŷ = -2.6s + 1.1
ŷ = -2.6*1.3 + 1.1
ŷ = -2.28
This is the estimated or predicted y value based on the input s = 1.3
Let's now compute the residual
e = residual error
e = (observed y value) - (predicted y value)
e = y - ŷ
e = 1.2 - (-2.28)
e = 1.2 + 2.28
e = 3.48 is the residual
A positive residual means that the predicted y value, aka ŷ, is an underestimate compared to the true observed value. In other words, the observed y value is higher than the ŷ value. Therefore, the line of best fit under-predicts the temperature change.

At one point on the trip, the miles are recorded as 15,121 when the gas tank is
75% full. Use a ratio equation to determine the miles per gallon the sedan
averages. Round your answer to the nearest whole number.
Answers
The sedan gets 1090 miles per gallon on average, according to the ratio equation.
What exactly is a ratio?A ratio is an ordered pair of numbers a and b, denoted by the a / b, where b is not equal to zero.
What is a ratio example?If there are eight oranges and six lemons in a bowl of fruit, the orange-to-lemon ratio is eight to six.
Given: When the gas tank is 75% full, the mileage is recorded as 15,121.
A sedan tank is typically 18.5 gallons in size. So it holds 13.875 gallons of gas if it is 75% full. If it traveled 15,121 miles, the mileage per gallon is 1090, rounded to the nearest whole number.
The calculation of miles per gallon using the ratio equation:
Let, x = miles per gallon
15121:13.875 is the ratio.
x/1= 15121/13.875
13.875x = 15121
x = 15121/13.875
x = 1089.80, which equates to 1090 miles per gallon
As a result, the ratio equation used to calculate the sedan's miles per gallon averages 1090 miles per gallon.

The output value of g( 3b ) in the function g( x ) = x² - x is 9b² - 3b.
What is the value of g( 3b ) in the function?A function is simply a relationship that maps one input to one output, that is, each x-value can only have one y-value.
Given the data in the question;
g( x ) = x² - xg( 3b ) = ?To determine the output value of g( 3b ), replace all the occurrence of x with 3b in the function and simplify.
g( x ) = x² - x
g( 3b ) = (3b)² - 3b
Apply product rule
g( 3b ) = 3²b² - 3b

if you placed $5 into an account that paid interest at a rate of 5%, and compounded interest yearly, how much would that account be worth in 100 years
Answers
After adding interest the sum would be worth $657.51 .
Interest is the amount paid over and above the original amount to a lender or depositor by a borrower or deposit-taking financial institution at a predetermined rate in the domains of finance and economics (the amount borrowed).
Interest differs from any fees the borrower may be required to pay to the lender or another party.interest also contrasts from a dividend, which is cash distributed to shareholders (owners) by a corporation from its profit or reserve, but not at a predefined rate or proportionally; rather, it is a portion of the reward or interest gained by risk-taking businessmen when revenue is made that surpasses all expenditures.Interest when the principal is $5 , time is 100 years and rate is 5%.
We know that from compound interest:
Amount = principal (1 + rate)ⁿ
Therefore
Amount = 5 (1 +0.05)¹⁰⁰
Amount = $657.5062...
Amount ≈ $657.51
Therefore adding interest the sum would be worth $657.51
the greatest common divisor of two integers is $(x 2)$ and their least common multiple is $x(x 2)$, where $x$ is a positive integer. if one of the integers is 24, what is the smallest possible value of the other one?
Answers
The greatest common divisor (24,6) is 6 and the least common multiple (24,6) is 24.
As per the question statement, the greatest common divisor of two integers is (x+2) and the least common multiple x(x+2). It is given that one of the integers is 24.
Let us assume that "b" is the value of other one.
greatest common divisor(24,b) = (x+2)
least common multiple(24,b) = x(x+2)
Formula:
greatest common divisor(24,b)*least common multiple(24,b) = 24*b
24*b = (x+2)*x(x+2)
[tex]b = \frac{x(x+2)^{2} }{24} \\[/tex]
Hence, the smallest possible value of the other one is "6" and x = 4.
Hence, the greatest common divisor (24,6) is 6 and the least common multiple (24,6) is 24.

can someone pls explain to me how to find y intercept
Answers
Answer:
(0, -5)
Explanation:
The function is represented by f(x), and the line graphed would be y= f(x). In slope-intercept form, the equation of a line is given by y= mx +c, where m is the slope and c is the y-intercept.
Since we know that the line is linear, any two points along the line would give us the same slope value. Since y-intercepts occur at x= 0, let the y-intercept be (0, y).
[tex]\boxed{ \text{slope} = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]
Slope between (-3, 1) and (1, -7)= slope between (-3, 1) and (0, y)
[tex] \frac{1 - ( -7 )}{ - 3 - 1} = \frac{y - 1}{0 - ( - 3)} [/tex]
[tex] \frac{1 + 7}{ - 4} = \frac{y - 1}{0 + 3} [/tex]
[tex] \frac{8}{ - 4} = \frac{y - 1}{3} [/tex]
[tex] - 2 = \frac{y - 1}{3} [/tex]
Multiply both sides by 3:
-2(3)= y- 1
-6= y -1
Add 1 to both sides:
y= -6 +1
y= -5
Thus, the y-intercept is (0, -5).
__________
Based on the image, however, we are to find the equation of the linear function in slope-intercept form.
The first step would be to find the slope between any two points, which would be -2. This is found using the slope formula, and we have calculated it above.
Substitute the value of the slope into y= mx +c:
y= -2x +c
The y-intercept can be found by substituting a pair of coordinates the line passes through.
When x= -3, y= 1,
1= -2(-3) +c
1= 6 +c
c= 1 -6
c= 5
Thus, the equation of the line is y= -2x +5.

PLEASE MARK AS BRAINLIEST IF YOU FOUND IT HELPFUL BECAUSE IT MAKES ME FEEL GOOD!
Step-by-step explanation:
Linear Standard Formy = mx + c;
The m equals the change in y divided by the change in x. If you choose left to right for y then you must do the same for x as well.
Δy = ( - 7 ) - ( - 15 ); Δx = 1 - 5;
Δy = - 7 + 15;
Δy = 8;
Δx = - 4;
m = 8 / - 4;
m = - 2;
y = - 2x + c;
Point SubstitutionPick a point (x, y) and sub it into the equation. Make sure to use brackets when subbing.
- 7 = - 2( 1 ) + c;
- 7 = - 2 + c;
Add 2 to both sides.
- 7 + 2 = - 2 + 2 + c;
- 5 = c;
c = - 5;
The c is the intercept.

Find WI if IE = 3
EW and YG are medians of AXYW
Answers
Based on the median and the centroid theorem, the length of WI is 6 units.
What is the Median of a Triangle?The line that joins the vertex of a triangle to the midpoint of the side it is directly opposite is called the median of a triangle.
According to the centroid theorem, since J is the centroid of triangle XYW, then:
the length of IE is 1/3 of the length of segment EW.
Thus, the equation that relates the length of the segments is;
IE = 1/3(EW)
Given that:
IE = 3 units
Now Substitute the value of IE into the equation:
3 = 1/3(EW)
3(3) = EW
9 = EW
EW = 9 units
Therefore:
The Length of WI = the length of EW - the length of IE

Length of WI = 9 - 3
