Josephine travels 32500+78000 yards at 60 mph
=110500yards
=62.78miles
time = distance/spped
time = distance/60
time=62.78/60
time=1.05 (1 hour 5 mins)
Marcus travels 78000(2)(square) +32500(2)
= 84500yards
=48 miles
time = distance/speed
time=48/45
time=1.07 (1 hour 7 mins)
a)Josephine arrives first
b)she arrives earlier by 2 mins.
Answer:
give the other peeson brainliest cuz y not
Step-by-step explanation:
Answer:
1 + x meters.
Step-by-step explanation:
A square has 4 equal sides so each side will have a length equal to the square root of the area.
Side length = √(1 + 2x + x^2)
= √(1 + x)(1 + x)
= 1 + x.

13) Given :-
Diameter : 8m
Radius = half of D = 4 cm
⇢C = 2πr = 2 × 3.14 × 4
≈ 25.13274
14) Radius = 6 cm
C = 2πr = 2 × 3.14 × 6
≈ 37.69911
15) C = 2πr = 2 × 3.14 × 7.1
≈ 44.61
16) C=2πr=2× 3.14 × 5.2
≈ 32.6

Step-by-step explanation:
<u>Step 1: Define</u>
14.9 + 1/3(-12 - 27x) - 33.2
x = -3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: 14.9 + 1/3(-12 - 27(-3)) - 33.2
- Multiply: 14.9 + 1/3(-12 + 81) - 33.2
- Add: 14.9 + 1/3(69) - 33.2
- Multiply: 14.9 + 23 - 33.2
- Add: 37.9 - 33.2
- Subtract: 4.7
