Answer:
A. 13.34
Step-by-step explanation:
This is the formula d=√((x_2-x_1)²+(y_2-y_1)²)
Plug in
d=√(-1-2)² + (4+9)²
d= √9 + 169
d= √178
d= 13.34
Answer:
w = 11
Step-by-step explanation:
<u>Step 1: Subtract 4 from both sides</u>
15 = w + 4
15 - 4 = w + 4 - 4
11 = w
Answer: w = 11
Answer:
$450>$235
Step-by-step explanation:
This is because, when 235 is subtracted from 450 there is a great difference thats why $450 is greater than $235
Answer:
2.9661582
Step-by-step explanation:
Answer:
61 c
Step-by-step explanation:
Circumference= 2πr = πd=3.14d
- 25 c, d = 24.3 mm ⇒ C=24.3*3.14 = 76.302
- 10 c, d = 17.9 mm ⇒ C=17.9*3.14 = 56.206
- 5 c, d = 21.2 mm ⇒ C=21.2*3.14 = 66.568
- 1 c, d = 19.1 mm ⇒ C=19.1*3.14 = 59.974
1*10 c+ 2*25 c+ 1*1 c = 61 c
