Answer:

The two regular cans of soup has a greater volume than the family size can of soup

Step-by-step explanation:

step 1

Find the volume of two regular cans of soup, each with a diameter of 8 cm and a height of 10 cm

The volume is equal to

V=2[\pi r^{2} h]

we have

r=8/2=4\ cm ----> the radius is half the diameter

h=10\ cm

substitute

V=2[\pi (4)^{2} (10)]

V=320\pi\ cm^{3}

step 2

Find the volume of one family can of soup, with a diameter of 10 cm and a height of 12 cm

The volume is equal to

V=\pi r^{2} h

we have

r=10/2=5\ cm ----> the radius is half the diameter

h=12\ cm

substitute

V=\pi (5)^{2} (12)

V=300\pi\ cm^{3}

therefore

Compare the volumes

320\pi\ cm^{3} > 300\pi\ cm^{3}

The two regular cans of soup has a greater volume than the family size can of soup

90% of runners who started a marathon completed it. Of those, 30% are men. If 270 men completed the marathon, then how many tota
il63 [147K]

Given- 90% of runner completed the marathon.

out of which 30% are man.

To proof -  let the total number of runner be y.

the men completed the marathon be 30% of the 90%.

thus we have

30% of 90% of y = 270

\frac{30}{100}×\frac{90}{100}×y = 270

now solving the above equation

we get

\\y=\frac{270\times 100\times 100}{90\times 30}

Thus solving the equation

y = 1000

Thus the total runners of men who completed marathon be 1000.

Hence proved

What polynomial should be added to 4x²+5x-8 in order to equal 0?
Klio2033 [76]
4x^2 + 5x - 8 + (- 4x^2 - 5x + 8) = 0

all ur doing is changing the signs so they will cancel each other out.

so ur adding : -4x^2 - 5x + 8

A countertop is 16 feet long and 3 feet wide. what is the area of the countertop in square meters.
Mrac [35]
Area=legnth times width
legnth=16 ft
width=3 ft
but wait, they want the area in squazre METERS
so convert feet to meters
1 foot=0.3048 meters

convert 16 feet and 3 feet to meters

16 feet=16 times 0.3048=4.8768
3 feet=3 times 0.3048=0.9144

so the area is now
legnth=4.8768 m
width=0.9144m

area=4.8768 m times 0.9144 m=4.45934592
round
4.0
answer is 4 square METERS

4 m^2

The diagonals of kite KITE intersect at point P. Which statement is true?
eduard

Based on the properties of a kite, the statement that is true is: D. KPE = TPE.

<h3>What is a Kite?</h3>

A kite is a quadrilateral in which its diagonals intersect at right angles.

Also, the non-vertex angles of a kite are congruent, that is they have equal measure.

Angle KPE and angle TPE in the given kite are right angles formed at the point of intersection of the two diagonals of the kite. They both equal 90 degrees.

Therefore, the true statement is:

D. KPE = TPE
