Answer$33.60
Step-by-step explanation:
First I added 23 and 6 to get $29
Then I figured out that 20 percent of 23 was 4.6 and added that to 29.
I came out with an answer of 33 dollar and sixty cents.
Hello!
You have already earned 12.25 dollars. So now, you need to earn $31.75. If each errand is $1.50, you can divide $31.75 by $1.50. You would get roughly 21.17. Since you can not do 21 errands and .17 of an errand, you would need to do about 22 errands to get the money you need, which is the $31.75. 1.50 times 22 is equal to thirty-three, so youd be getting about a dollar and 25 cents more than what you need. We can had 33 (what we earn from our 22 errands) to 12.25, which is what we already have, and we get 45.25! So you can earn more money than you need to earn.
Hope this helps, have an awesome day!
This is most easily done using the expanded form of the expression.
∫(9 -9t +t² -t³)dt = 9t -(9/2)t² +(1/3)t³ -(1/4)t⁴ +c
Answer: x^2-6x-8
Step-by-step explanation:
Step 1 : Factor - x^3-11x^2+22x+40: (x-5)(x^2-6x-8)/(x-5)
Step 2 : Divide, which should give you x^2-6x-8
Answer:
Bb or BB = 75%
Explanation:
In order to solve this question we have to use the Punnett square.
The Punnett square demonstrate the genetic results when two individuals cross. In order to make the square, we have to draw a big square with small squares inside, each representing all possible combinations of alleles. Since we have 2 alleles we have 4 possible combinations, that means 4 small squares.
In the up part of the square we introduce the alleles of the parent 1 and in the left part the alleles of parent 2. The results will be written in the small squares.
The attached image represents the crossing of two heterozygotes Bb x Bb
Represented by red there's 25% of probability of the puppy be homozigot BB, that means he will be black.
Represented by green there's 50% of probability of the puppy be heterozigot Bb, that means he also will be black, since B is dominant.
Represented by blue there's 25% of probability of the puppy be homozigot bb. That means he will be brown, since there's no dominant B there.
Total: 25% (BB) + 50%(Bb) = 75% of being black
