D , the answer is "six less than a number b"
Answer:
$5.24
Step-by-step explanation:
First, we need to find how many of each coin type we have. For pennies and dimes, we can take the percentage and divide by two for the number of coins.
18 / 2 = 9 pennies
36 / 2 = 18 dimes
We also know that there are three more nickels than there are dimes.
9 + 3 = 12 nickels
We can subtract the total number of nickels, pennies, and dimes from the total number of coins to get the number of quarters.
50 - 39 = 11 quarters
Then, we do the math to find the value.
9 x 0.01 = 0.09
18 x 0.10 = 1.80
12 x 0.05 = 0.60
11 x 0.25 = 2.75
2.75 + 1.80 + 0.60 + 0.09 = $5.24
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º

Use properties of logarithm to expand the logarithmic expression as much as possible. Where possible, evaluate logarithmic expressions without using calculator.
log4(4/x) = log4(4) - log4(x) = 1 - log4(x)
------------------------------------------------------
Evaluate the expression without using a calculator.
log7 1/root:7
log7(1/sqrt(7))
= log7(1) - log7(sqrt(7))
= 0 -(1/2)log7(7)
= 0-1/2
= -1/2</span>
The number of gigabytes of data that Christopher can use while staying within his budget exists 1.3 gigabytes.
<h3>How many gigabytes of data can he utilize while staying within his budget?</h3>
The number of gigabytes of data that Christopher can use while staying within his budget is 1.8 gigabytes.
Based on the information, we get
59 + (3 × g) = 62.90
59 + 3g = 62.90
simplifying the equation, we get
3g = 62.90 - 59
3g = 3.9
Divide both sides by 3, and we get
3g/3 = 3.9/3
g = 1.3
The number of gigabytes of data that Christopher can use while staying within his budget exists 1.3 gigabytes.
