Answer:
slope = -5/1
y-intercept = (0, -34)
Step-by-step explanation:
slope m = change in y ÷ change in x
= (-9 - -4) ÷ (-5 - -6)
= -5 ÷ 1
= -5/1
y = mx + b ⇒ y = -5x + b
substitute one of the points
-4 = (-5 x -6) + b
-4 = 30 + b
b = -34
Therefore, y-intercept = (0, -34)
Answer:
2, 3,4,6,8,9,12,18,36 and 72
Step-by-step explanation:
they can all divide 72
Per cent = per 100 <== ur answer
No. For fractions to be equal, both the numerators and denominators have to be proportional.
Since both denominators are 2, the denominators would have to be just 3 or just 4.
Answer:
Step-by-step explanation:
.
1) About how much medicine did he make in grams?
Dr. Mann mixed
9.357 g of chemical A,
12.082 g of chemical B,
7.502 g of chemical C
We can determine total amount of medicine that was prepared by Dr. Mann by summing up the chemicals (A,B,C)
=( 9.357grams of A + 12.082grams of B+ 7.502grams of C)
= 28.941 grams in total
The next step is to round up those chemicals value to their nearest tenth as asked by question
Dr. Mann mixed
9.357 g of chemical A= 9.4grams
12.082 g of chemical B,=12.1grams
7.502 g of chemical C =7.5grams
2)Estimate the amount of each chemical by rounding to the nearest tenth of a gram before finding the sum.
Then the sum after rounding up to nearest tenth is
(9.4grams +12.1grams + 7.5grams)
=29 gram
