The equation is Y= -x - 1
Answer:
370 millimeters of compound B is needed for 666 millimeters of solution.
Step-by-step explanation:
Given that:
4 millimeters of compound A are used for every 5 millimeters of compound B.
The scientist wants to make 666 millimeters of solution.
Let,
x be the multiplier number of the compounds in the solution.
Then,
4x + 5x = 666
9x = 666
Dividing both sides by 9
Millimeters of compound B = 5x = 5(74) = 370 millimeters
Hence,
370 millimeters of compound B is needed for 666 millimeters of solution.
Answer:
11 hours
Step-by-step explanation:
Let's set up a proportion so we can cross-multiply. We know that her rate is constant, so
Keeping units in helps to make sure that you have your fractions right-side-up. Now cross-multiply:
8x = 44*2
8x = 88
<u>x = 11 hours</u>
Step 1: add the amounts of your outstanding balances on your cards
EX: $1500+$1000+$500=$3000
step 2: add the amount of your creedit lines on your cards
EX: $6000+$3500+$2500=$12000
step 3: divide your total debt by your total credit
EX: $3000/$12000=25% or 0.25
Answer:
both sides are congruent meaning it is a 45/45 triangle. that makes y=45. you can then use sin(45)=x/12 which when solved is 8.49 approximately
