Answer:

64

Step-by-step explanation:

length(l)=8cm

breadth(b)=2cm

height(h)=4cm

volume=l×b×h

=8cm×2cm×4cm

=64cm³

Answer:

Step-by-step explanation:

Area is + 111.6 square meters

Formula : A/ 3.14 / 2

111.6 / 3.14 = 35.54

35.54 is the radius so multiply by 2 to get diameter .

35.54 / 2 = 17.77

Hope that’s right:)

Answer:x=8 so 60 for both aswers

Step-by-step explanation:10x-7x = 4+20 -> 3x=24 -> x=8

Answer:

Hmm i don't know is A B C D

CBA should be hmm 90 degrees I think

Then you should be able to calculate

it's so easy

Step-by-step explanation:

Answer:

D. x = 18; ∠DBC = 54

Step-by-step explanation:

m∠ABD + m∠CBD = 90°

2x + 3x = 90°

5x = 90°

x = 18°

m∠DBC = 3x

m∠DBC = 3(18°)

m∠DMC = 54°

Answer: 12.9

Step-by-step explanation:

lThe area of the triangles is 3/2 x 2.6 = 3.9/2 = 1.95. since there is 2 triangle do 1.95 x 2 = 3.9. and the area of the square is 3x3 = 9. All in all, 3.9 + 9 = 12.9.

Gl with that game

Answer:

Option 3

Step-by-step explanation:

We want to work out the surface-area

This is a cylinder and the formula for the surface area of a cylinder is :

2πrh+2πr^2

^ means to the power of

The radius is 15

The length is 18

2(3.14)(15)(18) + 2(3.14){15}^2

Part 1:

(6.28)(15)(18)

(6.28)(270)

1695.6

Part 2:

First, we do the exponents,

15^2 = 225

(6.28)(225)

1413

Part 3:

1695.6 + 1413 = 3108.6

Answer: 3108.6

Hope this helps :)

Answer:

23.0 ft to nearest 1./0.

Step-by-step explanation:

By Pythagoras:

34^2 = h^2 + 25^2      where h = the height of the building

h^2 = 34^2 - 25^2 = 531

h = 23.04 ft.

Answer:

The given polynomial x(x -3)(x +6)(x -7)= 0 is of degree 4. Therefore, it has 4 zeros as follows. So, x = 3 is the second zero. So, x = -6 is the third zero.

Answer:

Let x = # of hours Sophia spends ironing shirts

Let y = # of hours London spends ironing shirts

Equations: x + y = 11 and 40x + 25y= 365

Step-by-step explanation:

If Sophia and London worked a combined 11 hours, then one of our equations is : x + y = 11

They also note that Sophia and London both ironed 365 shirts, and Sophia irons 40 shirts per hour while London can iron 25 shirts per hour. Our next equation is : 40x + 25y= 365

Answer:

scientific notation: 1.71568627×10^11

Step-by-step explanation:

look up math-way and click on the calculator if that is not what you are looking for :)

c 1.72×10^2;172 homie

Everytime your X goes up by 1, your Y goes up by 4

making the space between 6 and 14 = 10

the exponential factor equation would look something like this

g(x)=3^x

meaning every time x goes up by 1, your exponential factor gets multiplied by 3, making 14y have an exponential factor of 1.

Answer:

19x I believe

Step-by-step explanation:

Added 10 and 9, left the x

Answer:

10+9x can't be combined to make a number

Step-by-step explanation:

This is because the 10 doesn't have the variable x so we can't combine them together

If the 10 had an x beside it, it would've become 19x, but it doesn't so it stays as is

Answer:

4939.22 feet cubed.  

Step-by-step explanation:

The formula for the volume of a cylinder is V=3.14*r^2*h

First we square the raidus, which is 11 in this problem.  11 squared is 121.

Next we multiply everything together.

3.14*121 is 379.94.  Then, 379.94 * the height, which is 13, is 4939.22.

Since our answer is already rounded to the nearest hundredth, the answer to this problem is 4939.22

Answer:

It's called a Diophantine Equation, and it's sometimes known as the “summing of three cubes”: Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100. One answer is x = 1, y = -1, and z = 2.
