Answer:

Step 1: Multiply the whole number by the denominator:

15 3/4 = 15.75

Step-by-step explanation:

Step 1: Multiply the whole number by the denominator:

15 × 4 = 60

Step 2: Add the product you got in Step 1 to the numerator:

60 + 3 = 63

Step 3: Divide the sum from Step 2 by the denominator:

63 ÷ 4 = 15.75

That's it folks! The answer to 15 3/4 in decimal form is displayed below:

What does x-4over5=6over7 what doesx=

Jobisdone [24]

$x-\frac{4}{5}=\frac{6}{7}$

Pass the $\frac{4}{5}$ but change the signal

$x=\frac{6}{7}+\frac{4}{5}$

now we have to make the minimum common multiple of 7 and 5, this number will be 35 therefore

$x=\frac{6*5}{35}+\frac{4*7}{35}$

$x=\frac{30}{35}+\frac{28}{35}$

now we can add both

$x=\frac{30}{35}+\frac{28}{35}$

$x=\frac{30+28}{35}$

$\boxed{\boxed{x=\frac{58}{35}}}$

Billy goes on the teacup ride at the local carnival. He is seated 16 inches from the center of his teacup, which is spinning at

Orlov [11]

Answer:

Billy’s angular velocity, is 1508.16 radians per second

Step-by-step explanation:

We have to find angular velocity in radians per second

we have given angular velocity w = 4 revolutions per minute

we have to convert revolutions into radians and minutes into seconds.

so, we use the following conversion:

1 rev = 2* pi radians (where pi = 22/7 or 3.142)

1 min = 60 sec

putting the values in our equation : w = 4 revolutions per minute

=> w= 4 * ( 2* 3.142) *60

=> w= 1508.16 radians per second

hence Billy’s angular velocity, is 1508.16 radians per second

A cylinder has volume 78 cm³. What is the volume of a cone with the same radius and height?

OleMash [197]

Answer:

The volume of the cone is $26\ cm^{3}$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2}h$

In this problem we have that

$V=78\ cm^{3}$

$78=\pi r^{2}h$ -----> equation A

The volume of a cone with the same radius and height is equal to

$V=\frac{1}{3}(\pi r^{2}h)$ -----> equation B

Substitute equation A in equation B

$V=\frac{1}{3}(78)$

$V=26\ cm^{3}$

PLEASE HELP EASY!!

Orlov [11]

Answer:

$2000

Step-by-step explanation:

The amount of interest you pay (for simple interest) is the product of the original amount, the interest rate and the time in years. Let x be the original amount (how much money she borrowed):

720=x(0.09)(4)

720=0.36x

x=2000
