5. Divide 1148 into two parts which
are in the ratio 11: 3.
How do you get the answer
Add the two parts of the ratio together: 11 + 3 = 14
Divide the original number by 14:
1148/14 = 82
Now multiply 82 by each part of the ratio:
82 x 11 = 902
82 x 3 = 246
Answer: 902: 246

What are similar triangles?
Similar triangles are two triangles that, while not sharing the same size, have the same proportions and angles measurements. Their corresponding angles are equal and the corresponding sides are in the same ratio.
Triangle PQR is similar to triangle STU because their angles are the same, and they share the same proportions in regards to their side lengths.
To find the unknown side of a similar triangle, set up two ratios equal to each other that represent the ratios of each triangle.
n is the hypothenuse of triangle PQR, so in your ratio, n should be in a fraction with 13, the hypothenuse length of triangle STU.
The fraction that n and 13 will be set equal to should also be the same side of the different triangle. (so either both of them are the shortest legs or both of them are the longest legs of their triangles)
Let's check each answer:
n is in the denominator and 13 is in the numerator. Great! 36 is the longest leg of triangle PQR and 12 is the longest leg in triangle STU, great! This choice is wrong, however. This is because both denominators and numerators should be set equal to their respective triangles. n is in triangle PQR, while 12 is in triangle STU, so they can not be set equal to each other.15 and 5 are both the shortest legs in their triangles, great! Unfortunately, 12 and n are both not hypothenuses, so this answer is incorrect. 15 and 5 are both the shortest legs in their respective triangles, but, again, n and 12 are not both hypothenuses.n is in the denominator and 13 is in the numerator. Great! 36 is the longest leg of triangle PQR and 12 is the longest leg in triangle STU, great! And, n is set equal to 36 (they are in the same triangle) and 13 is set equal to 12 (they are in the same triangle). This is the correct answer.*To check if your answer is correct, solve for n by cross multiplication and plug in your answer into the fraction. Both sides should simplify to the same fraction*

Blake and his brother are participating in their school’s food drive. Blake has collected 6 1/3 pounds of food and his brother has collected 5 3/4 pounds of food. Their goal is to collect 14 1/2 pounds of food by the end of the month. How many more pounds of food do they still need to collect to reach their goal? Answers shown below. (Ignore the one I chose, I randomly guessed)
They will need 2 5/12 more pounds to reach their goal.
Sum and difference of fractionsGiven the following information as shown:
Amount Blake collected = 6 1/3 poundsAmount his brother collected = 5 3/4 poundsIf their goal is to collect 14 1/2 pounds of food by the end of the month, the remaining food they need to collect will be expressed as:
y =14 1/2 - (6 1/3 + 5 3/4)
y = 14 1/2 - (19/3 + 23/4)
y = 29/2 - (76+69/12)
y = 29/2 - (145/12)
y = 174-145/12
y = 29/12
y = 2 5/12
Hence they will need 2 5/12 more pounds to reach their goal.

help me find x and y please
Answer:
Step-by-step explanation:
4 angles in a quadrilateral (sorry if i spelled that wrong) add up to 360
So we have : 11x+4 + 5y +5 +5x + 13y - 5 = 360
Then, we simplify as 16x + 4 + 18y = 360
=> 16x + 18y = 356
Divide both side by 2
8x + 9y = 178
So, x is a multiple of 8 and y is a multiple of 9
Then if we keep replacing, you will eventually come to an answer of y = 10 and x = 11

An item is regularly priced at $75 It is now priced at a discount of 60% off the regular price. What is the price now?
Answer:
Price is $ 30
Step-by-step explanation:
Regular price = $75
Discount = 60%
First we find the 60% of 75
( 75 × 60 ) ÷ 100 = 45
Now this answer with regular price
75 - 45 = 30
MARK BRAINLIEST IF YOU UNDERSTAND
Answer:
$ 30
Step-by-step explanation:
Regular price ⇒ $ 75
Discount ⇒ 60% off the regular price
First let us find the discount that they will give.
Let us solve now.
75 × 60% = $45
And now let us find the new price of the item.
For that you have to subtract the discount by the regular price.
New price = Regular price - Discount
= $ 75 - $ 45
= $ 30

A network administrator uses the function
f(x) 5* to model the number of computers a
virus spreads to after x hours.
How long will it take for the virus to spread to 50,000 computers ?
Functions are used to represent equations and graphs
It will take the virus 10000 hours to spread to 50000 computers
How to determine the number of hoursThe equation of the function is represented as:
f(x) = 5x
When the virus spreads to 50000 computers, the function becomes
50000 = 5x
Rewrite the function as:
5x = 50000
Divide both sides by 5
x = 10000
Hence, it will take the virus 10000 hours to spread to 50000 computers
