Answer:

The mother (Rhoda) is 46 years old.

The daughter (Tenica) is 18 years old

Step-by-step explanation:

Let the age of the mother (Rhoda) be m

Let the age of the daughter (Tenica) be d.

The sum of Rhonda and her daughter Tenica’s age is 64. This can be written as:

m + d = 64 ... (1)

The difference in their ages is 28. This can be written as:

m – d = 28 ... (2)

From the above illustrations, the equation obtained are:

m + d = 64 ... (1)

m – d = 28 ... (2)

Solving by elimination method:

Add equation 1 and 2 together

. m + d = 64

+ m – d = 28

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

2m = 92

Divide both side by 2

m = 92/2

m = 46

Substitute the value of m into any of the equation to obtain the value of d. Here, we shall use equation 1

m + d = 64

m = 46

46 + d = 64

Collect like terms

d = 64 – 46

d = 18

Therefore, the mother (Rhoda) is 46 years old and the daughter (Tenica) is 18 years old.

What’s 3x+6y=12 in the form y=mx+b
zhenek [66]
Hey there!

3x+6y=12

Divide both sides by 3 and your equation would now look like:
x+2y= 4
Move the x to the other side
2y= -x+4
Seprate the y by dividing both sides by 2
y= \frac{1}{2}x+2

find the volume of the cone. either enter exact answer in terms of pi or use 3.14 for pi and round your final answer to the near
SCORPION-xisa [38]

Answer:

6\pi u^3 = 18.8u^3

Step-by-step explanation:

the information we have is:

  • the radius of the circle in the base: r=3u (u for units)
  • and the height of the cone: h=2u

to find the volume we need the formula for the volume of a cone:

V=\frac{\pi r^2h}{3}

where r is the radius and h is the height.

Substituting the known values to find the volume:

V=\frac{\pi (3u)^2(2u)}{3} \\\\V=\frac{\pi (9u^2)(2u)}{3}\\ \\V=\frac{18\pi u^3}{3}\\ \\V=6\pi u^3

the volume in terms of \pi is 6\pi u^3

and if we substitute the value of pi: \pi=3.14 we get:

V=6(3.14)u^3\\V=18.8u^3
