Tai resized a photograph that was 8 inches by 10 inches so that it would fit on a 4 inch by 4 inch page. Find the maximum dimensions of the reduced photograph. An explanation wold be great, please. Thank you so much!

Answers

ok so it has to be max 4 inches when resized since the max size is 4 inches

10 is max of original so
they have to be shrunk in same ratio so find ratio of shrink
10 times ratio=4
divide both sides by 10
ratio=4/10=2/5
so multiply the measuremet by 2/5 to find new dimention

8 times 2/5=16/5=3 and 1/5=3.2

new dimentions is 4 by 3.2 inches

Paula and Daniel went to the store to by ingredients for 27 cakes. Paula paid for 2/3 of the cakes and Daniel paid 14 dollars for his portion. How much money did Paula and Daniel spend on their portion of the cake in total?

Answers

so Daniel paid for 1 third because paula paid for the other 2/3
he paid 14 dollars so that's 1/3 of the amount
if you times 14 by 3 you get 42
you times the 13 by 3 because Daniel paid 1/3 you have to times it by 3 to get a whole.
so the answer is that they paid 42 dollars all together.

Daniel paid for 1/3 of the total, b/c they had to pay for the total they had to pay for 3/3 1 whole. Paula paid for 2/3 and Daniel paid for the rest which is the 14 if he paid for 1/3 and Paula paid for 2/3 she paid twice as much as he did. 14x2=28 Paula paid 28 dollars out of the total of total 42dollars it cost

Irina predicted that she would sell 75 books, but she actually sold 95 books. Which expression would find the percent error? Use the table below to help answer the question.

Answers

There is no image of the table given.

Given:
approximate number = 75
exact number = 95

error = |approximate number - exact number| ÷ exact number
error = |(75-95)| / 95 = |20| / 95 = 0.21

percentage of error = 0.21 x 100% = 21%

Answer:

Given:

approximate number = 75

exact number = 95

error = |approximate number - exact number| ÷ exact number

error = |(75-95)| / 95 = |20| / 95 = 0.21

percentage of error = 0.21 x 100% = 21%

Find the value or values of p in the quadratic equation p2+13p-30=0

Answers

This is an examination to test your level of skill. By asking this quesiton to others, you do not show your true level and maybe be placed in a higher math than you are able.

factor
remember
if ab=0
assume that a and/or b=0

p^2+13p-30=0
fidn what 2 numbers add to 13 and multiply to -30
15 and -2
(p+15)(p-2)=0

set each to zero
p+15=0
p=-15

p-2=0
p=2

the roots are p=-15 and/or 2
