A recipe for sparkling grape jucie calle for 1 1/2 quarts of sparkling water and 3/4 quart of grape jucie. How much sparkling water would you need to mix with 9 quarts of grape jucie?
Answer: 18 quarts of sparkling water
Step-by-step explanation:
From the question, we are informed that a recipe for sparkling grape jucie calle for 1 1/2 quarts of sparkling water and 3/4 quart of grape jucie.
When there's an increase in the quarts of grape juice to 9, it simply means that the former grape juice has been multiplied 12 times (9 ÷ 3/4 = 9 × 4/3 = 12).
Therefore, we would also multiplybl the sparkling water given by 12 to get the new quantity needed. This will be:
= 1 1/2 × 12
= 3/2 × 12
= 18 quarts of sparkling water
A certain model car has a keypad with 5 numbers on the door. To open the door, 5 numbers must be entered in the correct
order and no number can be used more than once. What is the probability that someone could guess the correct code?
OA. Ito
OB.
OC.
OD.
Answer: A. [tex]\dfrac{1}{120}[/tex]
Step-by-step explanation:
Total digits on keypad = 5
According to permutation,
If repetition of digits is not allowed then the number of 5-digits passwords can be formed = 5!
= 5 x 4 x 3 x 2 x 1 [n!=n x (n-1) x (n-2)x ... x 1]
=120
The probability that someone guesses the correct code = [tex]\dfrac{\text{Number of correct codes}}{\text{Total possible codes}}[/tex]
[tex]=\dfrac{1}{120}[/tex]
Hence, the correct option is A.

Jeannie got a new pair of eye glasses. She was able to pay $15 at the
time she received her glasses. She will pay $12 each month on the
balance. The original cost of the glasses was $87.
b. How many months will it take Jeannie to pay for her glasses?
Answer:
6 months
Step-by-step explanation:
12x = 87
12x ÷ 12 = x
87 - 15 = 72
72 ÷ 12 = 6
x = 6 months
CHECK:
12 x 6 = 72 + 15 = 87
87 = 87
Answer:
6 months
Step-by-step explanation:
The equation would be: 15 + 12m = 87

Step-by-step explanation:
I gave all of the fractions a common denominator:

5/12= 5/12
1/4= 3/12
1/6= 2/12
Then, I added the 2/12 (from 0-1 hours) and 5/12 (from 1 1/2-2 hours). THis will give the complete range of 0-2 hours.

How to find the area of a parallelogram with 3 numbers?
14.8 square feet is the area of the given parallelogram.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
The area of a parallelogram is given by the formula:
Area = base x height
where the base is the distance between two parallel sides of the parallelogram.
In this case, the height is given as 2 feet, but we need to find the base.
Since the parallelogram has two pairs of parallel sides, we can use the width of 7.4 feet as the base.
Therefore, the area of the parallelogram can be calculated as:
Area = base x height = 7.4 ft x 2 ft = 14.8 square feet
So, the area of the parallelogram is 14.8 square feet.

Tiles
Answer:
36

12
Step-by-step explanation:
The circumfrence of a circle is as follows
2πr
For this question π=3.14
So we have
113.04=2πr
solve for r
r= 18
which means that diameter is 36
Just do the same thing with the other questions
18.84=2πr
r=3
31.4=2πr
r=5
37.68=2πr
r=6 which means that the diamater is 12

An angle measures 160° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
The two angles are 10 degrees and 170 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
Let the angle be called "x", and the supplementary angle be called "180-x"
Converting words to math: x-160=180-x
Add x to both sides: 2x-160=180
Simplify: 2x=20
Divide by 2: x=10

Answer:
885.45
Step-by-step explanation:
Testuo monthly payments will be around 885$
What is InterestIt is a fee paid for borrowing money or other assets.
• the amount borrowed is called the principal.
• the interest is expressed as a percentage rate of the principal
for a given time interval.
It is given that
Value of the car = $32000
Time period of loan repayment = 36 months
T = 3 years
Rate of Interest = 6.71%
10% down amount from 32000 = 3200 $
So the amount he is putting for finance = 32000 - (0.1 × 32000)
= $28800
Rate of interest can be calculated from
I = P x R x T
I = Interest, P = Principle, R = Rate, T = Time
= (6.71 * 28800 * 3)/(100*12)
= $ 483.12
This is total interest for an year
In one month, rate of interest
= 483.12/12
= $40.26
The principal amount that will be payable per month
= 28800/36
= $800
Total amount payable will be
= $ ( 800 + 40.26 )
= $840
Hence, we can conclude, Tetsuo needs to pay $840.26 as monthly installments, so in the options given it is 885$

In a March 2016 survey by Gallup of 1019 US
adults, 65% believe that global warming is due
more to human activity than natural changes in
the environment.
Assume the conditions for inference have been
met. Create a 95% confidence interval for the true proportion of US adults that believe global warming is due more to human activity than natural changes.
Answer:
Americans are taking global warming more seriously than at any time in the past eight years, according to several measures in Gallup's annual environment poll. Most emblematic is the rise in their stated concern about the issue. Sixty-four percent of U.S. adults say they are worried a "great deal" or "fair amount" about global warming, up from 55% at this time last year and the highest reading since 2008.
Mirroring this, the March 2-6 survey -- conducted at the close of what has reportedly been the warmest winter on record in the U.S. -- documents a slight increase in the percentage of Americans who believe the effects of global warming have already begun. Nearly six in 10 (59%) today say the effects have already begun, up from 55% in March 2015. Another 31%, up from 28% in 2015, believe the effects are not currently manifest but will be at some point in the future. That leaves only 10% saying the effects will never happen, down from 16% last year and the lowest since 2007.
