Answer:

C) About $85

Step-by-step explanation:

Please consider the complete question.

Carl puts $1.10 in his penny bank every day in the month of July (31 days). His total saving at the end of June is $55.00. What is the best estimate at the end of July?

A) about $25

B) about $115

C) about $85

D) about $66

First of all, we will round $1.10 to nearest whole number and round 31 to nearest tens as:

\$1.10\approx \$1

31\approx 30

So amount saved in 30 days would be 30 times $1.

\text{Savings in 30 days}=\$1\times 30

\text{Savings in 30 days}=\$30

Carl's savings at the end of July would be amount saved in June plus amount saved in July that is \$55+\$30=\$85

Therefore, the estimate for Carl's saving at the end of July is $85 and option C is the correct choice.

Which function is a horizontal compression of its parent function f(x)=x^7 by a factor of 4?
Leno4ka [110]

The function given to us is : f(x) = {(x)^7}

We want to see which function represents the horizontal compression of f(x) by a factor of 4

We can compress a function horizontally by multiplying the x by a constant number, in this case multiplying x by 4

So horizontal compression of f(x) = {(4*x)^7}

This matches with the option B = r (x) = {(4*x)^7}

Hence, your answer (B) is correct.

asambeis [7]
I divided the 297.25 by the 29 half bracelets already made. I got 10 1/4cm per half a bracelet.  So Candace needs another 10 1/4cm of string to finish the last one.

I hope that is clear.
