Answer:
10000 cows.
Step-by-step explanation:
Remainder before the 10% loss: (7650/9) x 10 = 8500
Total before any losses : (8500/85) x 100 = 10000
Hello! So the blocks are lined up in rows of 8. When you count the number of rows, there are 10 of them. 3 rows of 8 blocks are shaded out of 10 of them. That's 24 blocks shaded out of 80, because 8 * 10 is 80, and 3 * 8 is 24. Let's divide. 24/80 is 0.3.Let's multiply that by 100 to get it in percent form. 0.3 * 100 is 30. There. 30% of blocks are shaded in the picture.
Answer: m=12h
The dependent variable is m. The independent variable is h or hours worked. M or money earned is dependent because it will vary depending on the number of hours worked.
Step-by-step explanation:
A.
100%=all
so if 25% is dark and the rest is milk then
dark+milk=all
25%+milk=100%
minus 25% both sides
milk=75%
so
if milk chocolate=3lb then
3lb=75%
divide by 3
1lb=25%=dark chocolate
oops, I didn't use an equation
hmm
ratios and things
75%=milk
25%=dark
so we got
for m=pounds of milk chocolate
and d=dark chocolate
m/d=72/25 or m/d=3 and
m=3
duh
3/d=3
3=3d
1=d
B. 1 lb dark chocolate
We first have to find the factors of 7 and -3 and see which ones add up to -20.
factors of 7 are 1 and 7 factors of -3 are -1 and 3
7 and 1 -3 and 1
therefore, we get (x - 3) (7x + 1)
we can use the FOIL method to verify the answer.
