Answer:

14ml

Step-by-step explanation:

Since the ratio is 5 : 2, that means for every 5ml of water there will be 2ml of salt. 35 divided by 5 is 7. So, 7 times 2, which equals 14.

For what value of r is the parallelogram a rhombus
Gre4nikov [31]

Answer:

9

Step-by-step explanation:

7r+18=r²

r²-7r-18=0

factorizing

r²+2r-9r-18=0

r(r+2)-9(r+2=0

(r-9)(r+2)=0

r-9=0

r=9

check

(r²)=(9*9)=81

7r+18=7(9) + 8=81

SOVA2 [1]

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
