Answer:
Step-by-step explanation:
we know that
Haley's car gets at least 
miles per gallon
so
by proportion
Find the minimum number of gallons she'll need for a trip that is 
miles
Let n = the unknown number.
Quotient tells you use division.
n/7 = 39
Multiply both sides by 7 to cancel out the number in the denominator and isolate the variable.
n = 39(7) = 273
n = 273
The <em>correct answer</em> is:
400 + 10 + 2 + 0.6 + 0.03 + 0.008.
Explanation:
To write a number in expanded form, we use place values.
4 is in the hundreds place; this makes its value 400.
1 is in the tens place; this makes its value 10.
2 is in the ones place; this makes its value 2.
6 is in the tenths place; this makes its value 0.6.
3 is in the hundredths place; this makes its value 0.03.
8 is in the thousandths place; this makes its value 0.008.
To write this together, we find the sum:
400 + 10 + 2 + 0.6 + 0.03 + 0.008.
Answer:
equation: a/.5b=h
h=9
Step-by-step explanation:
a=1/2bh
divide both sides by 1/2b to get h alone
a/.5b=h
a/.5b=h
54/0.5(12)=h
54/6=h
9=h
