Answer:

9 3/7

Step-by-step explanation:

4 2/7 = 30/7

2 1/5 = 11/5

30/7 x 11/5 = 330/35

330/35 simplified is 9 3/7

Answer:

we can write

42/7 as 30/7

and

21/5 as 11/5

now

\frac{30}{7}  \times  \frac{11}{5}  \\  =  \frac{6}{7}  \times 11 \\  =  \frac{66}{7}

we can write 66/7 as 93/7

hence,

option D is correct.

A metallic sphere is immersed in water in a cylindrical container causing a rise in the level of water by 7.5cm if the cylinder
SVETLANKA909090 [29]

Answer:

6.51 cm

Step-by-step explanation:

Since the sphere causes the water level in the cylindrical container to rise and thus increase by its own volume, the volume of the sphere is V = 4πr³/3 where r = radius of sphere. The volume rise of the container is thus    V' = πR²h where R = radius of base of cylinder = 7 cm and h = height of water level = 7.5 cm.

Since V = V',

4πr³/3 = πR²h

dividing through by π, we have

4r³/3 = R²h

multiplying both sides by 3/4, we have

r³ = 3R²h/4

taking cube-root of both sides, we have

r = ∛(3R²h/4)

Substituting the values of the variables into the equation, we have

r = ∛(3(7 cm)² × 7.5 cm/4)

r = ∛(3 × 49 cm² × 7.5 cm/4)

r = ∛(1102.5cm³/4)

r = ∛(275.625 cm³)

r = 6.508 cm

r ≅ 6.51 cm to 2 decimal places

How can I use multiplication to find the quotient and evaluate the expression
adell [148]
When you divide two fractions, you do Keep, Change, Flip or KCF. So you keep the 3/5, you change the division sign to a multiplication sign, then flip the 3/15 to 15/3. So the new equation is 3/5x15/3. Then you simply the two sides so it becomes 1/1x3/1.....


Meaning the answer is 3.
