If the 35 teaspoons of blue paint are there. Then for the purple paint, we need to add 42 teaspoons of red paint.
What are ratio and proportion?A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A percentage is a mathematical expression in which two things are equal.
A mixture of purple paint contains 6 teaspoons of red paint and 5 teaspoons of blue paint.
To make the same shade of purple paint using 35 teaspoons of blue paint, then the amount of the red paint that you need will be
Let x be the amount of the red color needed.
Then we have
[tex]\rm \dfrac{x}{35} = \dfrac{6}{5}\\\\\\x \ \ = \dfrac{6 \times 35}{5}\\\\\\x \ \ = 6 \times 7\\\\\\x \ \ = 42 \ spoons[/tex]

Solve 11x+10y=32..... Will mark the brainliest!
The equation 11x + 10y = 32 is a linear equation, and the solution to the linear equation 11x + 10y = 32 is [tex]y = \frac{32 - 11x}{10}[/tex]
How to solve the equation?The equation is given as:
11x + 10y = 32
Subtract 11x from both sides
10y = 32 - 11x
Divide both sides by 10
[tex]y = \frac{32 - 11x}{10}[/tex]
Hence, the solution to the linear equation 11x + 10y = 32 is [tex]y = \frac{32 - 11x}{10}[/tex]

Avery bought stock in a company two years ago that was worth x dollars. During the first year that she owned the stock, it increased by 40%. During the second year the value of the stock decreased by 10%.
Answer:
The value of the stock can be found by: x × 1.26.
Step-by-step explanation:
The value of the stock in year one can be found by multiplying x by 1.4. This will represent a 40% increase in value. The following year, the stock decreases in value by 10%; this is represented by multiplication by 0.9. For example, if the value of the stock was $5:
5 × 1.4 = 7 (A 40% increase in value)
(5 × 1.4) * 0.90 = 6.3 (A further 10% decrease in value)
Rather than writing out the long version, we can simplfify by multiplying 1.4 by 0.9 to get 1.26 .We can also replace 5 with x to get a more general equation.

B. 2 units down, 5 units to the right
c. 2 units to the right, 5 units up
D. 2 units to the left, 5 units up
Answer:
C.) 2 units to the right, 5 units up
Step-by-step explanation:
The graph shifts left or right when a number modifies the "x" value before it is affected by any other number/function in the equation. This number is within parentheses with the "x". Subtracting a value moves the function to the right, whereas adding a value moves the function to the left. Therefore, since 2 is being subtracted from "x", the function has been shifted 2 units to the right.
The graph shifts up or down when the y-intercept changes. The y-intercept is the "b" value in a standard function. You can identify this value by plugging in zero to "x". If this number is positive, the function is shifted upwards, and if this number is negative, the function is shifted downwards. Therefore, since there is a 5 added to the equation, the function is shifted 5 units up.

Step-by-step explanation:theres only 2 sides on a coin
Answer: 50% , as likely as not .
Step-by-step explanation:
The probability of a 2 on the die is 1/6. The probability of a heads on the coin is 1/2. That means that (on average) half the time you roll a 2 you'll also get heads and the other half you'll get tails. What's half of 1/6?
The possibilities are:
1H 2H 3H 4H 5H 6H

Mrs. Welloff has just passed away, she has a $1,000,000 life insurance policy and her beneficiaries are her son and 3 grandchildren. She will leave 50% of her estate to her son and the other 50% to her three grandchildren equally. How much money will they each receive?
Son_______________
Grandchild #1_______________ Grandchild #2_______________ Grandchild #3_______________
Answer:
Step-by-step explanation:
1/2 of 1,000,000 is 500,000
the son will get 500,000$
now 500,000 divided by 3(since it's 3 grandkids) is
166666.66, because it's money, and you have to round to the nearest cent.
one will get 166666.67, but it doesn't matter who.
so
grand #1 = 166666.66$
grand #2 = 166666.66$
grand #3 = 166666.67$

im sorry I dont know
The printing company wants to minimize costs. What is the objective function? p = 45x 20y p = 25x 45y p = 25x 10y p = 25x 20y
The objective function of the printing company in a bid to minimize cost is; p = 25x + 20y.
What is the objective function of the company?The objective function in a linear programming problem is the real-valued function whose value is to be either minimized or maximized dependent on the constraints defined on the given linear programming problem over the set of feasible solutions. The objective function of a LPP is a linear function of the form z = ax + by in which case, z is the parameter to be optimised.
It therefore follows from the complete question that the objective function is; p = 25x + 20y. This follows from the fact that Supplier X charges $25 per case. Supplier Y charges $20 per case and the parameter to be optimised is price.
Remarks;
The complete question is as follows;
A printing company orders paper from two different suppliers. Supplier X charges $25 per case. Supplier Y charges $20 per case. The company needs to order at least 45 cases per day to meet demand and can order no more than 30 cases from Supplier X. The company needs no more than 2 times as many cases from Supplier Y as from Supplier X. Let x = the number of cases from Supplier X and y = the number of cases from Supplier Y.

2. Juliet coaches soccer and softball. She coaches both sports for a total of 18 hours each day. The soccer practice lasts 1.5 hours more than twice times as long as the softball practice.
(a) Write a system of equations to model the situation. Be sure to define your variables.
(b) How many hours each day does Juliet spend coaching each sport?
Show your work. Be sure to label appropriately.
An equation is formed of two equal expressions. Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
A.) Let the amount of time spent on soccer be represented by y, while the amount of time spent on softball is represented by x. Therefore, we can write,
x+y=18
y=2x+1.5
Hence, the system of equations to model the situation is x+y=18 and y=2x+1.5.
B.) Substitute the value of y from the second equation in the first equation, therefore,
x+y=18
x+2x+1.5=18
3x = 16.5
x = 5.5 hours
Substitute the value of x in the second equation, we will get,
y=2x+1.5
y=2(5.5)+1.5
y=11+1.5
y=12.5 hours
Hence, Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.

A bag contains 7 red, 3 yellow, and 4 blue marbles. What is the probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first?
A) 11/14
B) 1/7
C) 2/13
D) 75/91
Answer:
2/13
Step-by-step explanation:
4/14 × 7/13 when i simplify it becomes 2/13!!!
The probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is 2/13.
What is Probability?Probability helps us to know the chances of an event occurring. The sum of all the probabilities of an event is always equal to 1. The formula for probability is given as,
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The probability of getting a blue marble at the first try is,
Probability(Blue) = Number of blue marbles / Total number of marbles
= 4 / 14
The probability of getting a red marble at the second try is,
Probability(Red) = Number of Red marbles / Total number of marbles
= 7 / 13
The probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is,
Probability = Probability(Blue) × Probability(Red)
= (4/14) × (7/13)
= 2/13
Hence, the probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is 2/13.
