Answer:
61.1033594595 or 61.10
Step-by-step explanation:
Let the common difference between 2 consecutive pizzas be x.
The pizza is cut into slices of
90°, 90°-x, 90°-x-x, 90°-x-x-x, 90°-x-x-x-x, 90°-x-x-x-x-x,
that is
90°, 90°-x, 90°-2x, 90°-3x, 90°-4x, 90°-5x
the sum of these angles is 360°, so:
90°+90°-x+90°-2x+90°-3x+90°-4x+90°-5x=360°
90°*6-15x=360°
540°-360°=15x
180°=15x
x=12°
The degree measure of the fifth slice is 90°-4x=90°-4*12=90°-48=42°
Answer: 42°
Answer:
Step-by-step explanation:
Let b represent the number of cups of butter needed.
Let s represent the number of cups of sugar needed.
Let o represent the number of cups of oat needed.
Let f represent the number of cups of flour needed.
The recipe calls for two times as many cups of sugar as butter. It means that
s = 2b
Two times as many cups of oats as sugar. It means that
o = 2s
Two times as many cups of flour as oats. It means that
f = 2o
If Duane puts in one cup of butter, it means that b = 1
Therefore,
s = 2 × 1 = 2 cups
o = 2s = 2 × 2 = 4 cups
f = 2o = 2 × 4 = 8 cups
Therefore, he needs to add 8 cups of flour
Answer:
2 cm = 21 km
Step-by-step explanation:
2 cm = 21 km
This is why
3cm = 31.5 km
3/3 = 31.5/3 (To find out how much 1 cm is equal to)
1 cm = 10.5 km
And since 1 cm = 10.5 km is not there in the options... I tried to find out for 2 cm
So, I multiplied both sides by 2
1 cm = 10.5 km
1 *2 = 10.5 *2
So the answer become 2 cm = 21 km
