What is 0.36 expressed as a fraction in simplest form?
Answers
Answer:
0.36 = 36/100 = 9/25
so the simplest form is 9/25
let x = 0.3636363636…
then 100x = 36.363636…
Subtract the two from each other you get
100x - x = 36.363636… - 0.363636…
Notice that the repeating 36s line up perfectly and will subtract out to exactly 0/
99x = 36 : Divide both sides by 99
x = 36/99 : Divide out the common 9 in both the numerator and the denominator
x = 4/11

Gretchen made a paper cone to hold a gift for a friend. The paper cone was 14 inches high and had a
radius of 4 inches. Find the volume of the paper cone to the nearest tenth. Use 3.14 for it.
The volume of the paper cone is about
in?
Answers
Answer:
268.0 in²
Step-by-step explanation:
refer to attached graphic as reference
volume of cone, V = (1/3) πr²h
in our case, we are given r = 4" and h = 16"
substituting this into equation:
V = (1/3) πr²h
= (1/3) ·(3.14) · (4)²· (16)
= 267.94667 in²
= 268.0 in² (nearest tenth)

4 x 5 = 20
2 + 4 = 6
Soultion #1 = 2 + 5 + 4 + 3 = x
7 + 4 + 3 = x
11 + 3 = x
11 + 3 = 14

Mrs. Murphy by balloons garlands paper lanterns and banners to decorate a school party she got three times as many bags of balloons as paper lanterns seven more garlands than paper lanterns and for banners she paid $5.25 for each banner $6.50 for each paper lantern five dollars for each bag of balloons and $3.50 for each garland how many of each kind of decoration did she purchase if she paid $145.50
Pls use format that is shown on screenshot ty
Answers
Answer:
Paper Lanterns: 4
Bags of Balloons: 12
Garlands: 11
Banners: 4
Step-by-step explanation:
Cost of lanterns is $6.50
Mrs. Murphy bought 4 lanterns
Multiply the cost of one lantern ($6.50) by the number of lanterns bought (4)
6.50 multiplied by 4 equals 26
Cost of banners is $5.25
Mrs. Murphy bought 4 banners
Multiply the cost of one banner ($5.25) by the number of banners bought (4)
5.25 multiplied by 4 equals 21
Mrs. Murphy bought 3 times as many balloons as she did lanterns
So, you multiply the number of lanterns bought (4) by 3
This gives you 12
You then multiply the cost of each balloon ($5.00) by the number of balloons bought (12)
5.00 multiplied by 12 equals 60
Mrs. Murphy bought 7 more garlands as she did lanterns
So, you add 7 to the number of lanterns bought (4)
7 plus 4 equals 11
To find the cost of the total garlands bought
You multiply the cost of each garland ($3.50) by the number of garlands bought (11)
3.50 multiplied by 11 equals 38.5
Now you can add up the costs of all the items
26+21+60+38.5=145.50
145.50 was the total amount she spent so you know it is the correct answer.

so, the answer is -4.
Answer:
-4°C
Key:
( | | ) = these in between numbers is the absolute value. EXAMPLE: |-8| = 8
Step-by-step explanation:
If it was -9°C and it INCREASED by 5°C, you need to ADD.
-9°C + 5°C
*Because -9°C is a NEGATIVE NUMBER and is on the LEFT side of the number line, unlike 5°C, you need to count 5 units to the RIGHT of -9°C (Basically subtract the absolute values of each number (-9 = |9|) (5 = |5|) and make it either positive or negative, depending on which absolute value is the greatest (|9|).*
-9°C + 5°C OR |9| - |5|
|9°C| - |5°C| = |4°C| = -4°C
(because the greatest absolute value, |9|, is negative, the answer is too.)
