C=(-4,-6)
D=(1,-6)
lCDl=√(1-(-4))²+(-6-(-6))²
lCDl=√(1+4)²+(-6+6)²
lCDl=√5²+0²
lCDl=√25
lCDl=5
the distance between the CD points is 5
Answer:
235
Step-by-step explanation:
183.3 ÷ 0.78 = 235
This is due to the rules of division.
Answer:
$(12x -15)
Step-by-step explanation:
From the question;
- Sunny is paid $12 for working per hour
- Number of hours worked in a week = x
- Charges for late delivery during the week = $15
We are required to calculate his earnings in the course of the week
Therefore;
Gross amount earned = Payment per hour × number of hours
= $12 × x hours
= $12x
Net amount earned = Gross earnings - charges
= 12x - 15
Thus, the amount earned is $(12x -15)
<span>A tree must be connected by definition. This means that there can be no vertices of degree 0 in a tree.
Assume for contradiction that we have v vertices and that v - 1 have degree at least degree two. Then we know that the sum of the degrees of the vertices is at least 1 + 2(v-1) which is equal to 2v - 1. Therefore we know that the number of edges must be at least v- 1/2 . But this is impossible because a tree must have exactly v - 1 edges.
Thus we have shown by contradiction that every tree has at least two vertices.</span>
Answer: $5.81
Step-by-step explanation:
First, we round off the dinner bill of $38.65 to the nearest ten dollars, since 0.65 is greater than 0.5 benchmark for approximation, we round up. Therefore, 38.65 to the nearest tenth means we remove the last digit of the decimal= $38.7
15% tip on a dinner bill of $38.7 =
15/100 × 38.7
0.15 x 38.7= $5.805
