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)

Answers

They will need 2 5/12 more pounds to reach their goal.

Sum and difference of fractions

Given the following information as shown:

Amount Blake collected = 6 1/3 poundsAmount his brother collected = 5 3/4 pounds

If 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.

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*

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?

Answers

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

Hope this helps you :-)

Answers

Look at number 3 for the answer

Interval, 1 a.m. to 12 noon has the greater rate of snowfall, in inches per hour.

What is interval?

First step

1am - 12 noon will gives us 11 hours

6am - 3pm will gives us 9 hours

Second step

Inches per hour for 11 hours

=33-1/11

=32/11

=2.91 inches per hour

Inches per hour for 9 hours

=36-11/9

=25/11
=2.27 inches per hour

Therefore based on the above analysis Interval, 1 a.m. to 12 noon has the greater rate of snowfall, in inches per hour.

help me find x and y please

Answers

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
