If Francis wants to use as little flour as possible, which cookie should he make? Explain your reasoning.

Answers

If he wants to use as little flour as possible he should make the ginger snaps because if u make all of the denominators equivalent then those cookies use the least amount of flour. The peanut butter cookies use the most flour.

Cheri took out a loan for $14,350. The loan term was 3 years and Cheri’s payments were $625.77 per month. Since Cheri had filed for bankruptcy several years prior, she ended up paying a higher interest rate. With a better credit rating, her payments could have been $431.21 per month. How much more in interest did Cheri end up paying for her loan because of her bankruptcy? a. $5,836.80 b. $2,334.72 c. $8,624.16 d. $7,004.16

Answers

First we want to calculate total payments of each payment in order to find the interest. After that calculate the difference to get the answer

Total payments of 625.77
625.77×12months×3 years
=22,527.72
Interest paid
22,527.72−14,350
=8,177.72

Total payments of 431.21
431.21×12months×3 years
=15,523.56
Interest paid
15,523.56−14,350
=1,173.56

So how much more in interest did Cheri end up paying for her loan because of her bankruptcy
8,177.72−1,173.56
=7,004.16...answer

Four friends purchase 18.4 pounds of peaches. The peaches cost $1.75 per pound. The friends share the cost of the peaches equally. How do I do this!!!!?????????

Answers

You take the cost 18.4 multiply by 1.75 to find out the total cost of the peaches then divide by 4 to split the cast and you answer should be roughly 8

Answer:

Cost per friend = 8.05 $

Step-by-step explanation:

Four friends purchase 18.4 pounds of peaches.

The peaches cost $1.75 per pound.

Total cost of peach = Total pounds x Cost of peach per pound

Total cost of peach = 18.4 x 1.75 = 32.2 $

Number of friends dividing the cost equally = 4

[tex]\texttt{Cost per friend = }\frac{\texttt{Total cost of peach}}{\texttt{Number of friends dividing the cost equally}}\\\\\texttt{Cost per friend = }\frac{32.2}{4}=8.05\$[/tex]

Cost per friend = 8.05 $

You miss 3 out of 10 questions on a science quiz and 4 out of 15 questions on a math quiz. Which quiz has a higher percent of correct anwsers.




I did 3/10 so 0.3 and 4/15 which is 0.266... so would it be the science quiz???
Please explain

Answers

Your process is close!

Since 3/10 and 4/15 is the amount you missed you have to subtract that by 1.

1 - 0.3 = 0.70
1 - 0.26 = 0.74

So, you scored higher on the math quiz.

What is another way to write the expression ​ r⋅(18−3) ​?

Answers

i believe the first one would work

The other way to write the expression ​ r⋅(18−3) will be (r⋅18)−(r⋅3). Option A is correct.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that the expression is, r⋅(18−3)

We have to expand the expression in order to write the expression in the other way,

The expanding form can be used to indicate the value of each digit in a number in arithmetic. Numbers that are expressed as the sum of each digit multiplied by its place value are known as expanded numbers.

There are the different identity used in the expanded form as,Use the following identity as

a(b-c) = ab-ac

=r⋅(18−3)

=(r⋅18)−(r⋅3)

Thus, the other way to write the expression ​ r⋅(18−3) will be (r⋅18)−(r⋅3). Option A is correct.

Need help again just on number 3

Answers

Im going to start with my example for a. So you have to figure out how you can get to 8 from 2. So that would be 2*4=8. And whatever you do to the top, you must also do to the bottom. So for the top we multiplied by 4, so we also have to multiply the bottom by 4. So that would be 26*4=104. So your total/answer would be 8 teachers= 104 students. In another way, for f. it would be the same but you have to divide instead since 9 is bigger than 3. Hope this helped ! :)

Step-by-step explanation:

for fhg find the measure of the smallest angle <hfg if m<ghf equals 92 degrees and m<hgf equals 72 degrees

Answers

The correct answer is:

16°.

Explanation:

The sum of the measures of the angles of a triangle is 180°.  The two angles we have are 92° and 72°; together, these total to

92+72 = 164

This leaves us

180-164 = 16° for the remaining angle of the triangle.

Final answer:

To find the measure of the smallest angle

Explanation:

To find the measure of the smallest angle <hfg in triangle FHG, we need to use the fact that the sum of the angles in a triangle is 180 degrees. We are given that m<ghf = 92 degrees and m<hgf = 72 degrees. To find <hfg, subtract the measures of the other two angles from 180: 180 - 92 - 72 = 16 degrees. Therefore, the measure of the smallest angle <hfg is 16 degrees.
