Answer:

10 km

Step-by-step explanation:

volume of cube = s^3

1 m = 100 cm

volume = s^3 = (1 m)^3 = (100 cm)^3 = 1,000,000 cm^3

Since 1 m^3 = 1,000,000 cm^3, when you lay down the 1-cm cubes in a straight line with the edges touching, the line is 1,000,000 cm long.

1,000,000 cm = 10,000 m = 10 km

Answer:

In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.

Step-by-step explanation:

Answer:

1. Circumference = 87.92

2.Circumference = 43.96

Step-by-step explanation:

The first problem it had a radius. So in order to find the circumference you will have to use the formula 2πr. When you plug in the 14 yd in the radius spot it will look like 2π(14) when you solve it the answer will be 87.92

The second one has a diameter so the equation you will have to use is πd. Now you will have to plug the 14 cm where the diameter is which will look like π(14) when you solve it the answer will come out as 43.96

Answer:

C=12.8

On the caculator there are two buttons you need to press. 2nd and then x2. Once you press those add in 20.

You get 4.47 ROUND THAT to 4.5

12(2)+4.5(2)=C(2)

12×12=144 4.5×4.5=20.25

144+20.25=164.25

164.25=C(2)

On the caculator press 2nd and then x2

12.81=12.8

C=12.8

Answer:

98 inches

Answer:

1,092.8 ft

Step-by-step explanation:

The information here gives us a right triangle.

Let "y" represent the length of the base. (Adjacent length)

Height of the tower = 984 ft (opposite length)

Angle of elevation = 48° (reference angle)

Applying trigonometric ratios formula, we would have:

[tex] tan(\theta) = \frac{opposite}{adjacent} [/tex]

Plug in the values

[tex] tan(48) = \frac{y}{984} [/tex]

Multiply both sides by 984

[tex] tan(48) \times 984 = \frac{y}{984} \times 984 [/tex]

[tex] 1,092.8 ft = y [/tex] (nearest tenth)

Answer:

60

Step-by-step explanation:

The smallest number that is divisible by 15, 20 , and 30, must have the needed factors of each of these numbers:

15 = 3 * 5

20 = 2 * 2 * 5

30 = 2 * 3 * 5

Then the minimum common factor must have the following factors to satisfy the divisibility of all of the numbers above:

2 * 2 * 3 * 5 = 60

Answer:

x=17

Step-by-step explanation:

8x+20=11x-31

We simplify the equation to the form, which is simple to understand  

8x+20=11x-31

We move all terms containing x to the left and all other terms to the right.  

+8x-11x=-31-20

We simplify left and right side of the equation.  

-3x=-51

We divide both sides of the equation by -3 to get x.  

x=17

Answer:

17

Step-by-step explanation:

8x + 20 = 11x - 31

-8. -8

20 = 3× - 31

+31. +31

51 = 3x

/3. /3

x = 17

Answer:

8

Step-by-step explanation:

The number that is greater than 4 and less than 15 whose one of its factors is 4 and has an LCM of 32 when paired with 32 is 8

The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.

Given that one of my factors if 4 when you pair me with 32 we have a lcm of 32 i am greater than 4 less that 15

The clues are given as;

Factors of 4

Number greater than 4

Number less than 15

Also, the LCM of 8 and 32 is; 32

Hence, The mystery number that has the above properties will be 8

Answer:

Shorter leg=3

Longer leg=4

Step-by-step explanation:

Equations

In a right triangle, Pythagora's Theorem is satisfied. Being a the hypotenuse, b and c the legs of the triangle, then:

[tex]a^2=b^2+c^2[/tex]

Let's call

x=the shorter leg of the triangle

The longer leg is 1 cm longer than the shorter leg, thus:

x+1=the longer leg.

Since the hypotenuse is 5 cm long:

[tex]5^2=x^2+(x+1)^2[/tex]

Operating:

[tex]25=x^2+x^2+2x+1[/tex]

Swapping sides and simplifying:

[tex]2x^2+2x+1=25[/tex]

Subtracting 25:

[tex]2x^2+2x-24=0[/tex]

Dividing by 2:

[tex]x^2+x-12=0[/tex]

Factoring:

[tex](x-3)(x-4)=0[/tex]

We have two possible solutions:

x=3, x=4

The longer leg is x+1.

If x=3, x+1=4

If x=4, x+1=5. This solution is not valid because one leg would be equal to the hypotenuse.

Thus, the solution is:

Shorter leg=3

Longer leg=4
