Answer:
The graph can show you how much distilled water for 4 milliliters of ammonia and 5 milliliters of ammonia. You can use the graph to find 4.5 by find the midpoint of two amounts of distilled water. Such as, say that 4 milliliters of ammonia = 200 distilled water and 5 milliliters of ammonia= 250 distilled water. Then the answer to 4.5 milliliters of ammonia is 225 distilled water.
Step-by-step explanation:
Y α xz
y = kxz y = 72, when x = 6, and z = 4
72 = k*6*4
72 = k*24
24k = 72
k = 72/24
k = 3.
<span>y = kxz
</span>
<span>y = 3xz </span>
Finding y, when x = 3, z = 5.
y = 3xz
y = 3*3*5
y = 45
The answer for #8 is C.
7.1 x 7.1 = 50.41
For 10 I can't help you with because there are no answer choices shown on the photo. I would wait for another to help.
Answer:
y/x = k
Step-by-step explanation:
K is the constant of proportionality.
A = $125.73
I = A - P = $49.30
hey!
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 21.5%/100 = 0.215 per year.
Solving our equation:
A = 76.43(1 + (0.215 × 3)) = 125.72735
A = $125.73
The total amount accrued, principal plus interest, from simple interest on a principal of $76.43 at a rate of 21.5% per year for 3 years is $125.73.
