Answer:
AB = 20 metres
BC = 60 metres
Step-by-step explanation:
Let AB = x
Then, BC = 3x
<u><em>Condition:</em></u>
=> x+3x = 80
=> 4x = 80
Dividing both sides by 4
=> x = 20
So,
AB = 20 metres
BC = 3(20)
BC = 60 metres
Answer:
324 calories
Step-by-step explanation:
A box of cereal states that there are 81 cal in a 3/4 cup serving what is the unit rate for calories per cup how many calories are there in 3 cups of cereal
The unit rate for calories per cup = calories per cup
3/4 cup serving = 81 calories
3 cups of cereal = x calories
We Cross Multiply
3/4 × x = 81 × 3
x = (81 × 3) ÷ 3/4
x = 243 × 4/3
x = 324 calories per cup
There are 324 calories in 3 cups of cereal
Answer:
a. (0,5) and (4,0)
b. -5/4
c. y = -5/4x + 5
Step-by-step explanation:
The intercepts are where the line crosses the axis. It crosses at (0,5) and (4,0).
The slope of the line is how much it rises over how much it runs. It rises -5/4 from each intercept to the other.
The linear equation should be written as y = mx+b where b = 5 and the slope -5/4.
So the equation is y = -5/4x + 5.
We have an isosceles triangle with one angle 54 degrees and the other angles both labeled y degrees.
Triangle angles add to 180 degrees.
54 + y + y = 180
54 + 2y = 180
2y = 180 - 54 = 126
y = 126/2 = 63 degrees
Answer: 63 degrees
Check: 63+63+54=180 good
