Step-by-step explanation:
x + y = 25
x - y = 13
x.y = ?
x + y = 25
y = 25 - x
x - y = 13
x - 25 + x = 13
2x = 13 + 25
2x = 38
x = 38/2
x = 19
y = 25 - x
y = 25 - 19
y = 6
(x, y) = (19,6)
So, find their product!!
= x.y
= 19 × 6
= 114

Answer:
1. 0.55
2. 11.36 (12)
Step-by-step explanation:
Question 1
If the price of one gallon is 2.09, and the conversion rate of gallon to litre is:
1 gallon : 3.785l
We can divide the cost of one gallon by the equivalent of 1 gallon in litres:
2.09 ÷ 3.785 = 0.5521
= 0.55
Question 2
If one quart is 4kg, and we need to find the total number of quarts in 100 pounds, we can convert kg into lbs and divide:
1kg = 2.2lbs
4kg = 4(2.2)lbs
4kg = 8.8lbs
Now divide 100lbs by this:
100 ÷ 8.8 = 11.3636
= 11.36
Technically this should be rounded up to 12 quarts as you wouldn't be able to have 0.36 quarts but just in case.
Hope this helps!

Answer:
not similar 2 and 3
Step-by-step explanation:
Select a point not on the line. Show that the ordered pair represented by this point is not a solution of the equation 8x + y = 200.
(5, 40) is not on the line.
Equation: 8x + y = 200.
Plug in our choosen point: 8(5) + (40) = 200.
Mulitply: 40 + 40 = 200
Add: 80=200
Answer: 80≠200
This works for your problem.

Maria went last minute Christmas shopping, and found that the store was having a sale: 1 throw blanket was $3. Including tax (8.25%), her bill came out to $29.22 - How many throw blankets did Maria buy?
Answer:
8
Step-by-step explanation:
Answer:
Step-by-step explanation:
The cost of one throw blanket was 3(1.0825) = 3.2475
1 blanket costs 3.2475
x blankets cost 29.22 Cross multiply
3.2475 x = 29.22 Divide by 3.2475
x = 29.22/3.2475
x = 9 dollars. The person writing the question and I differ by 1/433 because we rounded at different times. You should round at the end.
An environmentalist wishes to conduct a hypothesis test on the percentage of cars driven in the city that are hybrids. Is it sufficient for him to use a simple random sample of 189 cars if hybrids currently account for 6% of the car sales in the country and he claims that the percentage of hybrids in the city is higher than that
Using the condition for the hypothesis test of a proportion, it is found that since there are at least 10 successes and 10 failures in the sample, it is sufficient for him to use a simple random sample of 189 cars.
To test an hypothesis involving a proportion p in a sample of size n, it is needed that there are at least 10 successes and 10 failures, that is, these following conditions are needed.
[tex]np \geq 10[/tex][tex]n(1 - p) \geq 10[/tex]In this problem:
6% of the cars are hybrids, hence [tex]p = 0.06[/tex]Sample of 189 cars, hence [tex]n = 189[/tex].Then:
[tex]np = 189(0.06) = 11.34 \geq 10[/tex]
[tex]n(1 - p) = 189(0.94) = 177.66 \geq 10[/tex]
Hence, since there are at least 10 successes and 10 failures in the sample, it is sufficient for him to use a simple random sample of 189 cars.

Someone please help! Will mark brainliest!!! 2.200/54°20
Answer:
Step-by-step explanation:
Hmmmm... Several big questions about this simple phrase.
1) Are you using the European convention of using a period as an American would use a comma? Does 2.200 mean 2200 or 2.2 with precision to the nearest thousandths.
I will ASSUME you are using the European form and 2.200 = 2200
2) PEMDAS says multiply and divide are equal weight so complete as read left to right.
2200/54 = 40.740740740...
40.740740740...•20 = 814.814814814814...
or, if this is really supposed to be
2.200 / (54(20)) then = 2.037037037037...
Then again, the symbol between the 4 and last 2 is not really a multiplication symbol. It's more of a circle. Now does that mean degrees? and if degrees, are they temperature or angular? Or does that circle indicate an exponent of zero, in which case 54° = 1 and PEMDAS would say the result is 0.110 to an American and 110 to a European.
What we have here is a failure to communicate.

How can you multiply fractions and mixed numbers?
Step-by-step explanation:
In order to multiply fractions and mixed numbers, you must first transform the mixed number into a single fraction (will most likely turn into an improper fraction). An improper fraction is a fraction where the numerator is greater than the denominator.
Example:Suppose that you were given the following fractions to multiply:
[tex]\large\mathsf{\frac{5}{7}\:\times\:2\frac{3}{5}}[/tex]
The first step is to transform the mixed fraction, [tex]\large\mathsf{2\:\frac{3}{5}}[/tex], into a single fraction.
You will have to multiply the denominator with the whole number, then add the numerator. The denominator does not change when you do this transformation processs.
The mixed fraction will now turn into the following improper fraction:
[tex]\large\mathsf{2\:\frac{3}{5}}[/tex] ⇒ [tex]\large\mathsf{\frac{13}{5}}[/tex]
Now, you will be able to multiply [tex]\large\mathsf{\frac{5}{7}}[/tex] and [tex]\large\mathsf{\frac{13}{5}}[/tex] together by multiplying the numerator, 5 and 13 and the denominator, 7 and 5.
[tex]\large\mathsf{\frac{5}{7}\:\times\:\frac{13}{5}\:=\:\frac{5\:\times\:13}{7\:\times\:5}\:=\:\frac{65}{35}}[/tex]
Since the product of the two fractions is an improper fraction, it is often customary to express the fraction into its lowest terms. Given the improper fraction, [tex]\large\mathsf{\frac{65}{35}}[/tex], the greatest common factor between 65 and 35 is 5.
Hence, we could simply divide the numerator and the denominator by [tex]\large\mathsf{\frac{5}{5}}[/tex] to simplify the fraction.
[tex]\large\mathsf{\frac{65}{35}\:\div\:\frac{5}{5}\:=\:\frac{13}{7}}[/tex]
Therefore, the final answer is: [tex]\large\mathsf{\frac{13}{7}}[/tex] . To transform this improper fraction into a mixed number, simply divide its numerator by the denominator, thereby resulting into the following mixed number: [tex]\large\mathsf{1\:\frac{6}{7}}[/tex].
Write the fraction as an 1/15 equivalent fraction with a denominator of 45.
9514 1404 393
Answer:
3/45
Step-by-step explanation:
To find the numerator, multiply the desired denominator by the fraction.
x/45 = 1/15
x = (45)(1/15) = 45/15 = 3
The equivalent fraction is 3/45.
Which of the following is a solution of 4 Vx-3 = 16?
Answer:
19/4
Step-by-step explanation:
4x - 3 = 16
4x - 3 + 3 = 16 + 3
Simplify:
4x - 3 + 3 = 16 + 3
4X = 16 + 3
4x = 16 + 3
4X = 19
Then divide:
4x = 19
4X/4 = 19/4
Simplify:
x = 19/4.

What is the length of the hypotenuse?
Answer:
In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
