Answer:
Large pie = 13
small pie = 7
Step-by-step explanation:
hope this helps!
Use Pythagorean theorem.
a^2 + b^2 = c^2
D.
21^2 + 72^2 = 75^2
441 + 5184 = 5625
Answer:
cost of ice cream cones = $1.75
cost of ice cream sandwiches = $2.25
Step-by-step explanation:
Let
x = cost of ice cream cones
y = cost of ice cream sandwiches
3x + 4y = 14.25 (1)
5x + 2y = 13.25 (2)
Multiply (2) by 2
10x + 4y = 26.50 (3)
3x + 4y = 14.25 (1)
Subtract (1) from (3)
10x - 3x = 26.50 - 14.25
7x = 12.25
x = 12.25/7
x = $1.75
Substitute x = 1.75 into (1)
3x + 4y = 14.25
3(1.75) + 4y = 14.25
5.25 + 4y = 14.25
4y = 14.25 - 5.25
4y = 9
y = 9/4
y = $2.25
Step-by-step explanation:
x²y = k, where k is a real constant.
When x = 3.5, y = 8.
=> (3.5)²(8) = k, k = 98.
When y = 8/9,
we have x²(8/9) = (98).
=> x² = 110.25
=> x = 10.5 or x = -10.5.
Since we want the negative value,
the answer is x = -10.5.
Answer:
AP = RA = 1.5 cm
PB = BQ = 8.5 cm
QC = CR = 3.5 cm
Step-by-step explanation:
The distance from the vertex to the two nearest tangent points is the same. If we say the distance AP = RA = x, then PB = BQ = 10-x, and QC = CR = 5 -x.
Since we know
BQ +QC = 12
We can substitute the above expressions involving x to find what x is.
(10 -x) +(5 -x) = 12
15 -2x = 12
x = (15 -12)/2 = 1.5
This tells us ...
AP = RA = 1.5 cm
PB = BQ = 8.5 cm
QC = CR = 3.5 cm
