in shop a crunchy peanut butter costs $325 for 250g
in shop b crunchy peanut butter costs $408 for 340g
which shop gives better value for money. explain your answer
Answers
Answer:
shop b
Step-by-step explanation:
We can find for example how much 100 grams of peanut butter cost in each shop using a proportion
shop A 100 : 250 = x : 325
x = (325 * 100) / 250 = $130
shop B 100 : 340 = x : 408
x = (408 * 100)/ 340 = $120
We discovered that shop B is cheaper

Dana takes a sheet of paper and cuts from one corner to the opposite corner, making two triangles. If the piece of paper is 8 inches long and 5 inches wide, how long is the diagonal cut that Dana made? If necessary, round to the nearest tenth.
Answers
Answer:
9.4 inches
Step-by-step explanation:
The triangle formed is aright angled triangle with the right angle between the length and width of the paper cut hence the diagonal represents the hypotenuse side.
Recall that Pythagoras theorem states that
a^2 + b^2 = c^2 where c is the hypotenuse side and a, b are the opposite and adjacent sides
Hence
8^2 + 5^2 = c^2
c^2 = 64 + 25
= 89
Finding the roots of both sides
c = 9.433981132
To the nearest tenth
c = 9.4 inches

Osvoldo has a goal of getting at least 30, percent of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of carbohydrates, and 55 grams were from whole grains.
Answers
Answer:
No
He ate only 25% from whole grains
He ate 5% less grams from his goal
Step-by-step explanation:
Osvoldo has a goal of getting at least 30, percent of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of carbohydrates, and 55 grams were from whole grains.
Did Osvoldo meet his goal? Why? , Osvoldo ate grams of whole grains than his goal.
Percent of whole grains ate = grams of whole grain / total carbohydrates) x 100
(55/220) x 100 = 25%
This is less than his goal of 30% by (30% - 25%) 5%
Answer:
No, Osvoldo 11 grams of whole grains less than his goal.
Step-by-step explanation:
30% x 220
30% = 30/100 = 30 ÷ 100
30 ÷ 100 = 0.3
0.3 x 220 = 66
66 - 51 = 11
