Answer:
10
4
Step-by-step explanation:
Purple: This makes two trapezoids. A=(a+b)/2 times h
1st = (4+1)/2 x 1 = 2.5
2nd = (4+1)/2 x 3 = 5/2 x 3 = 2.5x3=7.5
Total = 2.5+7.5=10
Green: if you draw a line down the center, you can divide these into two more manageable triangles. A=1/2bh
1st = 1/2x2x2 = 2
2nd = 1/2x2x2 = 2
Total = 2+2=4
Answer:
10 gallons of gas.
Step-by-step explanation:
250/9 = how many miles 1 gallon of gas will take
250/9 = 27.78
1 gallon of gas = 27.78 miles
275/27.78 = 9.90 gallons
9.90 gallons round up to 10 gallons
Therefore, Trey would need 10 gallons of gas to drive 275 miles.
A. Nancy has the greatest spread because her longest training time was 105 and her shortest being 82, making the spread 23, and Peter’s spread is only... Longest: 112 Shortest: 92 making it 20!
b. Nancy. Middle %50 would be Peter’s 110-92 making the spread 18, and Nancy’s spread is 93-90 making the spread making it 12
c. The spreads tell us they are very close to each other, and just Peter has more time but a less spread than Nancy.
The length in standard notation is 2.17 + 8 = 10.17 ft
<h3>How to write in standard notation? </h3>
A standard notation is a form of writing a given number, an equation, or an expression in a form that follows certain rules.
For example 9.5 billions years can be represented as follows;
9,500,000,000 years.
Therefore, let's write 8 ft and 26 inches in standard form.
12 inches = 1 ft
26 inches = ?
cross multiply
length(ft) = 26 / 12
length(ft) = 2.16666666667
length(ft) = 2.17 ft
Therefore, the length in standard notation is 2.17 + 8 = 10.17 ft
