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?
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

Government agencies keep data about the income distribution of the population. The Aoki family and Alexander family live in a country with 11,000 families. The Aoki family's income is at the 56th percentile. The Alexander family's income is at the 78th percentile.
See image down below for the 2 questions and answer choices.
Pleeeaaase help mee soooon!!! Thank you!!!!!!!!!
Answer:
earns 56% of families in country
Answer:
(a) Both the Aoki family and the Alexander Family earn more than the median income(b) The Aoki family earns about 56% of the highest income in the countryStep-by-step explanation:
56th percentile and 78th percentile are both above the 50%
For the first question the answer is B, both the families earn more than half of the population.
For the second question the answer is C, the Aoki family is at 56th percentile, which means its position is top 56%, not more or less
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.
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?
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.
A scale drawing of Joshua's living room is shown below: A rectangle is shown. The length of the rectangle is labeled as length equal to 6 cm, and the width is labeled as width equal to 4 cm. If each 2 cm on the scale drawing equals 4 feet, what are the actual dimensions of the room?
Answer:
Drawing : Actual
Scale
2 : 10
2 cm : 10 feet
Length
6 cm : 30 feet
Width
4 cm : 20 feet
The actual dimensions of the room are - Length=30 feet, Width=20 feet.

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?
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.
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
Yesterday I ran 9.6 miles at an average speed of 0.4 miles per 5 minutes. How long did it take me to run the 96 miles?
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
0.4 miles 0.4 miles

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.
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
Answer:
Part A: 4x = -5(x - 18)
Part B: 40° (both, A & B)

What is 35% of 220? A. .77 B. 7.7 C. 77 D. 770
Answer:
77
Step-by-step explanation:
35% of 220 is equivalent to 77.
What is function?A function is a relation between a dependent and independent variable.
Mathematically, we can write → y = f(x) = ax + b.
Given is to find 35% of 220.
Let 35% of 220 be {x}. Then, we can write -
{x} = 35/100 x 220
{x} = 35/10 x 22
{x} = 35 x 2.2
{x} = 77
Therefore, 35% of 220 is equivalent to 77.

C.) 7√3
Step-by-step explanation:
a^2 + b^2 = c^2
x^2 + 7^2 = 14^2
x^2 + 49 = 196
x^2 = 196 - 49
x^2 = 147
√x^2 = √147
√147 = √49 • √3
√49 = 7
√3 = √3
