the mass of a monarch butterfly is 0.56 g what is the mass of 4 monarch butterflies?

Answers

You multiply .56x4 or add .56 4 times. The mass of all 4 monarch butterflies is 2.24

The solution is: The mass of all 4 monarch butterflies is 2.24

Here, we have,

the mass of a monarch butterfly is 0.56 g,  we nee to find  the mass of 4 monarch butterflies

if 1 butterfly is 0.56 grams,

then 4 must be 0.56 x 4.

                        =2.24

we multiply .56x4 = 2.24

or add .56,  4 times.

i.e. .56 + .56 + .56 + .56 = 2.24

The mass of all 4 monarch butterflies is 2.24

we have worked out the answer :

0.56 x 4 = 2.24g

Hence, The solution is: The mass of all 4 monarch butterflies is 2.24

This triangle is a multiple of one of the triples listed here. What is the hypotenuse?

Answers

Answer:

50 units

Step-by-step explanation:

you use Pythagorean-theorem  which means A^2+B^2 =C^2

It does not matter the order of A and B because it is adding. But C is the hypotenuse.

If we plug in the # this is what it looks like...

14^2 +48^2=C^2

        or

48^2+14^2=C^2

14*14= 196

48*48=2,304

then you add

196+2,304=C^2

2,500= C^2

and you can use a calculator for this part you do 2,500

with the 2,500 you use the sign as in the picture and it gives you...

50

which means 50*50 = 2,500

50 units is the answer

Answer:

1.) The height of the cone is 10 and the volume is 2355

2a.) Height 5= Volume 1177.5.

2b.) Height 30= Volume 7065

3.) (I'm not exactly sure because I haven't done this in a while.)

I guess 30= diameter

4.) 1 unit of height = 235.5 units of volume

Sorry if i messed up 3 or 4. I haven't calculated this stuff in a while.

Step-by-step explanation:

1.) It says the height of the cone on the horizontal ray and volume of the cone of the vertical ray.

2.) Divide 10 by 2 to get 5 height - Divide 2355 by 2= 1177.5

2b.) Multiply 10 by 3= 30 height - Multiply 2355 by 3= 7065

3.) r= √3× (V ÷ h) subtitute: r= √3× (2355 ÷ 3.14× 10)

simplify: r= 14.99... Diameter = 2 radius so about 30

4.) Divide 2355 by 10 to get the unit ratio. 1 unit of height is 235.5 volume.

A. does 24 ft = 2in ?

Answers

No, your answer should be,

[tex]\Huge\boxed{288}[/tex]

To convert feet into inches, you multiply the length value by 12. Your mistake is you got it mixed-up. 24ft doesn't equal 2in, but 24in equals 2ft, because instead of multiplying 12, you divide by 12.

24ft → 288in

24 × 12 = 288

24in → 2ft

24 ÷ 12 = 2

Hence, 24ft doesn't equal 2in.

24 doesn’t equal 2.
