Here is a formula for the amount of water needed to cook rice.
w = 1.5r + 0.5
w is the number of cups of water needed.
r is the number of cups of rice to be cooked.
(a) How many cups of water are needed to cook 7 cups of rice?
(b) How many cups of rice can be cooked with 20 cups of water?
Answers
Step-by-step explanation:
So w =water.
1 cup of water is equal to 1.5 times the volume of rice +0.5
so it'd be (11x1.5) + 0.5 for part A and for part B so you'd need to rearrange the equation which i'm not confident on .
W= (1.5 x11)+0.5
W=17
29=(1.5 x r) + 0.5
28.5=1.5r
19= r

Screen-printing a batch of shirts requires 3 minutes per shirt in addition to 13 minutes of initial set-up time. If it takes 616 minutes to screen-print a batch of shirts, how many shirts are in the batch?
Answers
Answer: 201 shirts
Step-by-step explanation:
Let x= total shirts in the batch.
Total time taken for x shirts = Initial set-up time + (Time require per shirt) × (x)
[tex]\Rightarrow\ 616= 13+3x\\\\\Rightarrow\ 3x=616-13\\\\\Rightarrow\ 3x= 603\\\\\Rightarrow\ x=\dfrac{603}{3}\\\\\Rightarrow\ x=201[/tex]
Hence, there are 201 shirts in the batch.
There are 15 animals in a barn. These animals are horses and chickens. There are 44 legs in all. Write a system of equations to determine how many horses and chickens are in the barn.
Answers
Answer:
x=8, y=7
Step-by-step explanation:
Lets keep x as the number of chickens and y as the number of horses.
Since each horse has 4 legs and each chicken has 2 legs we get our first equation to be
2x+4y=44
This is because we need to multiply the number of chickens times 2 to get the number of chicken legs, and same for the horses except 4 because they have 4 legs.
the second equation is
x+y=15
next we can use the substitution method to solve.
First we solve for x
x+y=15
x=15-y
We can substitute this into the first equation
2x+4y=44
2(15-y)+4y=44
30-2y+4y=44
30+2y=44
2y=14
y=7
Now we can substitute this into the original equation, x+y=15 and get the equation x+7=15, x=8
The final answer is x=8, y=7

In a set of three lines, a pair of parallel lines is intersected by a transversal. The intersection forms eight special angles. Two of the special angles, A and B, are corresponding angles. For the set of parallel lines intersected by a transversal, A=4x and B=-5(x-18). Part A: Write an equation to represent the corresponding relationship between A and B. Part B: Use the equation to find the measures of A and B.
Answers
Answer:
Part A: 4x = -5(x - 18)
Part B: 40° (both, A & B)
Step by step explanation:we already know the fact that angles A and B are corresponding angles.
By definition, this means that A and B are equal in degree measure

Answers
Answer:
Step-by-step explanation:
This is how we do it in college, I hope I can be of some help.
First, you multiple 9.6 miles with 5 minutes. Then, you divide your answer with 0.4 miles. Next, you cancel the two mile units because of division and then be left with 120 minutes.
9.6 miles x 5 minutes = 48 miles x minute = 120 minutes

the simple interest on a sum of money for 2 years at 12% per annum is rupees 1380
(i) find the sum of money
(ii) the compound interest on this sum for 1 year payable half-yearly at the same rate.
Answers
Answer:
5750
710.7
Step-by-step explanation:
Simple interest = principal. * rate * time
Principal (p) = sum of money
1380 = p * 0.12 * 2
1380 = 0.24p
p = 1380 / 0.24
p = 5750 rupees.
The compound interest :
A = P(1 + r/n)^nt
A = final amount
n = number of compounding times per period
t = period
A = 5750(1 + 0.12/2)^2*1
A = 5750(1 + 0.06)^2
A = 5750(1.06)^2
A = 5750 * 1.1236
A = 6460.7
Hence, compound interest is :
Final amount - principal
6460.7 - 5750
= 710.7 rupees

A shade of purple is made with 4 ounces of red paint, 5 ounces of blue paint, 2 ounces of white paint How many ounces of blue paint are needed to make an 88 ounce batch of paint?
Answers
Answer:
40 ounces.
Step-by-step explanation:
We are going to find this by using ratios.
Given that we have 4 ounces of red paint, 5 ounces of blue paint, and 2 ounces of white paint. The total ounces of paint in a shade of purple is 4 + 5 + 2 = 11.
The fraction of the paint that is blue is thus ounce of blue paint/total ounce of paint = 5/11
So, the number of ounces of blue paint are needed to make an 88 ounce batch of paint is fraction of blue paint × 88 ounces = 5/11 × 88
= 5 × 8
= 40 ounces.
