Answer:
The value of y is 36, and the value of z is 54.
Step-by-step explanation:
y has to be a number that can sit at 2y and then add itself to itself and become 3y.
40 is too high, and 35 is too low. Level it out, and you get 36.
I’m sorry but how r we supposed to answer there’s no picture
<span>Coffee mug is cylindrical in shape.
So, volume of cylinder = V=π r² h
Mass of coffee = 400 g which is filled to a depth of 8.00 cm. so, h=8.00 cm
density of water = 1 g/cmÂł
Density = mass/volume
1 g/cmÂł = 400g / volume
volume = (400g) / (1 g/cmÂł)
volume = 400 cmÂł
As,
volume of cylinder -
V=π r² h
400 cm³ = π r^2 x 8.00 cm
π r² = (400 cm³) / (8.00 cm)
π r² = 50 cm²
r² = (50)/ π
r² = 15.924 cm²
Taking square root on both sides -
r =3.99 cm
r =4.00 cm
Answer: Thhe inside radius of coffee mug is 4.00 cm</span>
Answer:
10.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Hypotenuse = AC = 8 cm
AB = 6 cm
BC² + AB² = AC²
BC² = AC² - AB²
= 8² - 6²
= 64 - 36
= 28
BC = 5.29 cm
