It will take three days !!

Answer:

2 Days

Step-by-step explanation:

If April is able to complete the project in half the amount of time that Bob is, this means that she works twice as fast as Bob. If they work together, then, April will complete twice as much of the work as Bob will. This system can be represented by a simple equation.

If the project takes April 3 days to complete the project, this means that she is able to complete 1/3 of the project every day she works.

If the project takes bob 6 days to complete the project, this means that he is able to complete 1/6 of the project every day he works.

Therefore, to complete one whole project, the equation would be:

1=1/6x+1/3x

↓

1=1/2x

↓

2=x

Working together, they will complete the project in 2 days.

If f(z)= sqrt z2+8z , then how much does f(z) increase as z goes from 7 to 8?
Nuetrik [128]

Answer:

B

Step-by-step explanation:

f(7)=\sqrt{7^2+8*7}=\sqrt{49+56}=\sqrt{105} \approx 10.247\\f(8)=\sqrt{8^2+8*8}=\sqrt{128}=8\sqrt{2} \approx 11.314\\f(8)-f(7)=11.314-10.247=1.067 \approx 1.07

Suppose you had D dollars in your bank account. you spent $22 but have at least $28 left. how much money did you have initially?
nalin [4]

Answer:

Answer:

d--22→ 28

d→ 50

Step-by-step explanation:

Let d dollars be the initial amount in your bank account.

We have been given that you spent $22, so the amount left after spending $22 will be: .

We are also told that after spending $22, you have at least $28. This means that the amount left after spending $22 will be greater than or equal to $28.

We can represent this information in an equation as:

Therefore, the inequality represents the initial amount of money you had.

Now let us solve for d by adding 22 to both sides of our inequality.

Therefore, initially you had at least $50.

The expression (x^22) (x^7)^3 is equivalent to x^p. What is the value of p?
SpyIntel [72]

Answer:

x^87

Step-by-step explanation:

Multiplying x^22 and x^7 results in x^29.

Then we have:

(x^29)^3 = x^87

Recall that (a^b)^c = a^(bc) and that a^b*a^c = a^(b + c)
