Answer: 119°
Step-by-step explanation:
A circle equals 360° degress. If you subtract the two angles shown in the picture you'll get 238°.
Now vertical angles are congurent thus if we divide 238 into 2 we get 119°.
Answer:
5305.1647 times
Step-by-step explanation:
The Circumference of a circle : πd
d = diameter of circle = 30 cm
Circumference of wheel = π * 30cm = 94.247779 cm
1km to cm
1km = 100000cm
5 km = 500000 cm
Hence, number of times wheel rotate on a 5km journey :
500000 cm / 94.247779 cm
= 5305.1647 times
Answer:
Milk $3.60
Water $1.80
Chips $0.90.
Step-by-step explanation:
If w = cost of 1 bottle of water, m = cost of 1 gal of milk and c cost of 1 bag of chips we have.
4m + 6w + 5c = 29.7
Also we have w = 2c and m = 1.8 + w.
From the first equation we have c = w/2.
So substituting for c and m in the initial equation we have:
4(1.8 + w) + 6w + 5(w/2) = 29.7
7.2 + 4w + 6w + 2.5w = 29.7
12.5w = 22.5
w = 1. 80.
So c = w/2 = 1.8/2 = 0.90.
and m = 1.8 + 1.8 = 3.60.
