Answer:
65 degrees, because vertical angles are always congruent.
Step-by-step explanation:
First we need to find the heigh of the soda can be rearanging the volume formula, . We can make that We know that V is 36 and radius is half of the diameter, so radius is 2.
h = 2.87
Now, we can use the height to figure out the volume of a cone. The volume of a cone is
R is 2 again and h is 2.87
12.56*.96 = 12.0576
So a cone with a volume of 12.0576 is the largest that will fit into the soda can
Equation is 4b + 5m = €10.90, and values of b and m are €1.35 and €1.1 respectively.
Step-by-step explanation:
- Step 1: Find equation for Thursday's sales.
Given b = price of a loaf of bread and m = price of one liter of milk
Total sales = €10.90
Equation ⇒ 4b + 5m = €10.90
- Step 2: Find the values of b and m.
3b + 2m = 6.25 ----- (1)
4b + 5m = 10.90 ---- (2)
Multiply eq(1) by 5 and eq(2) by 2 to make coefficients of m equal.
15b + 10m = 31.25
8b + 10m = 21.8
Subtract eq(2) from eq(1)
⇒ 7b = 9.45
⇒ b = 9.45/7 = €1.35
Substitute for b and find m using eq(1).
⇒ 3 × 1.35 + 2m = 6.25
⇒ 4.05 + 2m = 6.25
⇒ 2m = 2.2
∴∴ m = 2.2/2 = €1.1
Answer:
This is not question but I think the question might be what the total cost is 95.50

Answer:
Step-by-step explanation:
You are given an angle, the adjacent side to the angle, and need the hypotenuse of the triangle. Use Cos x to find the missing side.
Cos α = (adjacent side)/(hypotenuse)
Cos 45 = 10/x
x(Cos 45) = 10 (multiply both sides by x to get rid of the fraction)
x = 10/(Cos 45) (divide both sides by Cos 45 to isolate x
Cos 45 = (√2)/2 so we have...
x = 10/[(√2)/2]
now simplify...
x = 10*(2/√2)
x = 20/√2
x = (20√2)/[(√2)(√2)
x = (20√2)/2
x = 10√2
or x = 14.1421 if you use a calculator
