Answer:
<h3>72 units</h3>
Step-by-step explanation:
Given D,E, and F are collinear points and E is between D and F, then the expression DE + EF = DF.... 1 is true
If DE is six times the length of EF, then;
DE = 6DF
DF = DE/6 .....2
Substitute equation 2 into 1;
DE + EF = DF
DE + DE/6 = DF
find the LCM
(6DE+DE)/6 = DF
cross multiply
6DE+DE = 6DF
7DE = 6DF
Given DF = 84units
7DE = 6(84)
7DE = 504
Divide both sides by 7
7DE/7 = 504/7
DE = 72
Hence the length of segment DE is 72units
Answer:
1. 62
2. 13
3. 6
4. 18
5. 3
Step-by-step explanation:
1. Let's use pemdas
16*1/2= 8
32 / 4 * 8 - 2
8*8 - 2
64 - 2
= 62
2. Let's use pemdas
5*2/5 = 2
20 / 2 + 3
10 +3
= 13
3. Let's use pemdas
1/2 * 24 / 3 +2
12 / 3 +2
4 +2
=6
4. Let's use pemdas
2 * (6 / 2 + 8) -4
2 * 11 - 4
22 - 4
= 18
5. Let's use pemdas
(28 / 7 +6 / 3) * 1/2
( 4 + 2) *1/2
6 *1/2
= 3
W is 3.5/2 in fraction and 1.75 ind decimal
Complete Question
Find the circumference of the pizza to the nearest hundredth.
When Diameter = 18 in.
Answer:
56.55 inches
Step-by-step explanation:
A pizza is circular in shape.
The formula for the circumference of a circle is given as:
πD
Where D = Diameter
From the above question,
Diameter = 18 inches
Hence,
Circumference of the circular pizza = π × 18 inches
= 56.548667765 inches
Approximately = 56.55 inches
