You may need to sit down with your parents or with your teacher and
go over how to add and subtract fractions.
1). "Perimeter" means the distance all the way around the square.
With a square, all 4 sides are the same length. With <u>this</u> square,
every side is 1-1/4 inches long.
Perimeter = length of all 4 sides= (1-1/4) + (1-1/4) + (1-1/4) + (1-1/4) =
(1 + 1 + 1 + 1) + (1/4 + 1/4 + 1/4 + 1/4) =
4 + 4/4 = <em>5 inches</em> .
2). (2-3/8) + (1-7/8) = (2 + 1) + (3/8 + 7/8) =
(3) + (10/8) =
3 + 1-1/4 = <em>4-1/4 .</em>
3). The difference is (1-1/6) minus (5/6) .
Before you start to do the subtraction, write the (1-1/6) as (7/6) .
Then the subtraction is (7/6) - (5/6) = 2/6 = <em>1/3</em> .
4). This one is almost the same kind of problem as #3.
It's another subtraction.
If you need (2-1/4) all together, and you already have (1-3/8),
then the amount you still have to find, or borrow, or buy, is the
difference between those two numbers.
(2-1/4) minus (1-3/8) .
The trick is to write the (2-1/4) in some form that you'll be able to
subtract (1-3/8) from it. When I learned how to do that, it was called
'borrowing', but I think now it's called 'regrouping'.
We need to work on (2-1/4):
-- take 1 from the 2, and change it into fourths.
2-1/4 = 1 and 4/4 and 1/4 = 1 and 5/4
-- Now, take those 5/4, and turn them into eighths.
Each fourth makes 2 eighths. So 5/4 = 10/8.
Now, the (2-1/4) has turned into 1-10/8 .
We did NOT change the value. It's still the same amount
as 2-1/4 , but it's just written in a different way.
And now the subtraction is easy:
(2-1/4) minus (1-3/8) =
(1-10/8) minus (1-3/8) = (zero and 7/8).
You need <em>7/8 inch</em> more string than you already have.
Answer: Volume = 97.6
Step-by-step explanation:
Volume of the cone first
V = 1/3 h π r²
<u>h = 0.7</u>
<u>r = 2</u>
V = 1/3 × 0.7 × 2² × 3.14
V = 1/3 × 0.7 × 4 × 3.14
V = 1/3 × 8.792
V = 2.93
Then find the volume of the cylinder if the cone was there.
V = π r² h
<u>r = 2</u>
<u>h = 8 </u>
V = 3.14 × 2² × 8
V = 3.14 × 4 × 8
V = 3.14 × 32
V = 100.48
Now you subtract the volume of the cone from the cylinder.
100.48 - 2.93 = 97.55
Rounded to the nearest tenth is 97.6
Hope this was helpful, I know it is a lot to look at but I tried my best.
Also, can I get brainliest? I worked really hard on this.
Notice that x is part of the two triangles.for the bigger triangle
92+85+x=180
177+x=180
x=3
in the smaller triangle
y+100+x=180
since x=3
y+100+3=180
y=77
Answer: 10.2 mph
Step-by-step explanation:
total runtime of the bike trip: 4hrs, 42 mi total
12 hrs has her 122 mi from home
our rate can be found by taking the miles and dividing it by the hours:
122/12 = 10.2
