Robert is pouring wax into cylindrical candle containers. Approximately 226.19 cubic inches of wax fill one candle jar. Which im

blsea [12.9K]

Answer:

The first choice.

Step-by-step explanation:

The volume must be about 226.19 in^3.

Volume of a cylinder = area of base * height4

= πr^2h = 226.19

r^2 = 226.19 / πh.

Consider the first of the choices:-

When h = 8 , r^2 = 226.19 /8π = 8.9998

So r = 3.00 to nearest hundredth.

So this is the required image.

Chukwu, Abdul and kunle are to share $142, such that Abdul gets $11.00 less than Chukwu and $7.00 more than Kunle. How much is C

Elena-2011 [213]

Answer:

Chukwu's share is of $57.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

Chukwu's share is x.

Abdul's share is y.

Kunle's share is z.

Chukwu, Abdul and kunle are to share $142

This means that $x + y + z = 142$

Abdul gets $11.00 less than Chukwu

This means that:

$y = x - 11$

$7.00 more than Kunle.

This means that:

$y = z + 7$

$z = y - 7$

$z = x - 11 - 7$

$z = x - 18$

How much is Chukwu's share?

We want to find x, so:

$x + y + z = 142$

$x + x - 11 + x - 18 = 142$

$3x - 29 = 142$

$3x = 171$

$x = \frac{171}{3}$

$x = 57$

Chukwu's share is of $57.

a 24 foot tall streetlight casts a shadow that is 18 feet long. how long of a shadow is cast by a nearby parking meter post that

Elanso [62]

9514 1404 393

Answer:

3 ft

Step-by-step explanation:

The post is 4/24 = 1/6 as tall as the streetlight, so we expect its shadow to be 1/6 as long as that of the streetlight:

(1/6)(18 ft) = 3 ft

The parking meter post shadow is 3 feet long.

Help PLEASE!! This is my last question of this QUIZ THAN I'LL BE FREE!! 20 pts!!!!

EastWind [94]

Answer:

y=0.012x+0.65

Step-by-step explanation:

And again y=mx+c

we have 4 point given in the question

(50,1.25) ( 100,1.85) ( 150,2.45) (200,3.05)

we can find the M ( gradient/Slope) by using 2 of them with the formula

I am using the first 2 (50,1.25) ( 100,1.85)

$\frac{y2-y1}{x2-x1}$

$\frac{1.85-1.25}{100-50} \\\frac{0.6}{50}$

which in decimal form is 0.012

with that cross out the first option as its wrong

now to find c, like in the previous two question, put the m, x and y in the equation and solve for C

I am gonna use the 3rd coordinates for this one (150,2.45)

2.45=0.012(150)+c

2.45=1.8+c

0=1.8-2.45+c

-c=-0.65

c=0.65

So our completed equation is y=0.012x+0.65

The third answer is correct :)
