x: cups of chocolate chips needed for one batch
y: cups of peanut butter chips needed for one batch
A. y=1.5x
B. x= 5y
C. x=1.5y
D. y=5x​

C. x = 1.5y

This is the answer

As, 3y/2x = 1.5y/x

So, by this ratio we get,

x = 1.5y

Paul and Quinn share some money in a ratio 3:2, Paul gets 60 more than Quinn, how much does Quinn get

Answers

Answer: 120

Step-by-step explanation:

3+2=5

Let x be the amount of money to be shared

Paul’s share which is (3/5)x is 60+ Quinn’s share which is (2/5)x

Therefore

(3/5)x= (2/5)x + 60

(3/5)x - (2/5)x= 60

(x/5)=60

Cross multiply

x= 60*5=300

It means that Quinn’s share is (2/5)(300)= 120

The amount of money that Paul and Quinn have will be $180 and $120, respectively.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Paul and Quinn share some cash in a proportion of 3:2, Paul gets 60 a larger number than Quinn.

Let 'x' be the share of Paul and 'y' be the share of Quinn. Then the equation is given as,

x: y = 3: 2          ...1

x = y + 60         ...2

From equations 1 and 2, then we have

(y + 60) / y = 3/2

2y + 120 = 3y

y = 120

Then the value of the variable 'x' is given as,

x = 120 + 60

x = 180

The amount of money that Paul and Quinn have will be $180 and $120, respectively.

There were 450 people at a play. The admission price was $2 for adults and $1 for children. The admission receipts were $680. How many adults in how many children attended

Answers

Answer:

Adults= 110

Children= 340

Step-by-step explanation:

Given data

let adults be x

and children be y

x+y= 450----------1

2x+y=680---------2

from 1

x= 450-y

put this in 2

2(450-y)=680

900-2y=680

900-680=2y

220=2y

y= 220/2

y= 110

x+110= 450

x= 450-110

x=340

There are some Chicken and rabbits in a cage. There are 20 heads and 62 feet in total, the question is: how many chicken and rabbits in the cage?​

Answers

Answer:There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?

Step-by-step explanation

There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?

Legs of a chicken = 2

Legs of a rabbit = 4

Total heads = 72

Total legs= 200

Let's assume that each of them has minimum 2 legs.

So 72*2 = 144 legs

Remaining legs: 200-144= 56

These remaining legs belong to rabbit because rabbit has 4 legs each.

2*Rabbits= 56

Rabbits= 56/2 = 28

Out of 72, 28 are rabbits. So there are 72-28= 44 chicken.

○=> Correct option :[tex]\color{plum}\tt\bold{(A) \: 200.96}[/tex]○=> Steps to derive correct option :

Distance from the tip to the middle of the turbine = Radius of the circular turbine

Radius of the circular turbine = 32 meters

Circumference of the circular turbine = distance the turbine will travel in one revolution

We know that :

[tex]\tt \: \color{hotpink}circumference \: of \: a \: circle \color{plum}= 2\pi r[/tex]

Circumference of the circular turbine :

[tex] = \tt2 \times \frac{22}{7} \times 32 [/tex]

[tex] = \tt\frac{2 \times 22}{7} \times 32[/tex]

[tex] =\tt \frac{44}{7} \times 32[/tex]

[tex] =\tt \frac{1408}{7} [/tex]

[tex]\color{plum} =\tt 201.06 \: m[/tex]

▪︎201.06 m can be roughly rounded off to 200.96.

▪︎Thus, the distance the turbine will cover in one revolution = 200.96 m

Answers

Answer:

Step-by-step explanation:

The answer is 1 2 and 4

The correct options are 1 and 3.

The expression can be written as 4n + 7, involving multiplication and addition.

Given is a verbal expression "Four times a number increased by seven"

We need to convert it into algebraic expression.

So,

Replace "a number" with the variable, n.

This means we replace the phrase "a number" in the expression with the variable "n".

So, the expression becomes "Four times n increased by seven," which can be written as "4n + 7."

The two operations are multiplication and addition.

This option is correct.

The expression involves two operations: multiplication and addition.

We have "Four times a number" which means we multiply the number by 4, and then "increased by seven" means we add 7 to the result.

So, the expression can be written as 4n + 7, where 4n represents the multiplication and +7 represents the addition.

The expression is written as 4n + 7.

This option is correct. The given expression "Four times a number increased by seven" can be written as 4n + 7, where 4n represents the multiplication of the number by 4 and +7 represents the addition of 7 to the result.

So, the correct options are 1 and 3.

Answer:

3n - 17

Step-by-step explanation:

This phrase includes subtraction (“less than”) and multiplication (“times”). We are multiplying a number (3) by the variable to create the term 3n. Subtraction is not commutative, so order does matter. 17 less than 3n means we have 3n and take 17 away: 3n - 17.

Ir (2p-1,p) is a solution of the equation 9y + 12 = 10x, then find the value of p​

Answers

Answer:

p = 2

Step-by-step explanation:

Since, (2p-1,p) is a solution of the equation 9y + 12 = 10x.

Therefore, plug x = 2p - 1 & y = p in the above equation.

9p + 12 = 10(2p - 1)

9p + 12 = 20p - 10

12 + 10 = 20p - 9p

22 = 11p

p = 22/11
