Jen has 6 yards of fabric and wants to make a new dress and shorts she used 3 1/3 yards of the fabric on her new dress how much
kodGreya [7K]

Answer:

2\frac{2}{3}\ yards

Step-by-step explanation:

we know that

To find out how much fabric Jen has left for the shorts, subtract the yards of fabric used in her new dress from the total yards of fabric Jen has.

so

6-3\frac{1}{3}

Convert mixed number to an improper fraction

3\frac{1}{3}=\frac{3*3+1}{3}=\frac{10}{3}

substitute

6-3\frac{1}{3}=6-\frac{10}{3}=\frac{8}{3}\ yards

Convert to mixed number

\frac{8}{3}\ yards=\frac{6}{3}+\frac{2}{3}=2\frac{2}{3}\ yards

HURRY I WILL GIVE BRAINLIEST!!
nika2105 [10]
Hi there! 

The formula for the volume of a cone is V = 1/3(pi x r^2 x h). Using this formula, we can solve for the volume of the cone.

WORK:
V = 1/3(3.14 x 6.5^2 x 14)
V = 1857.31 / 3
V = 619.10 cm^3

ANSWER:
A) 619.10cm^3

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

A triangle has a height that is 4 /3 the length of its base. If the length of its base is 24 cm, what is its area?
ASHA 777 [7]
Triangle Area = ½ * height * base

base = 24 therefore
height = (4/3) * base = (4/3) * base = 32 cm

Triangle Area = ½ * 32 * 24
= 384 cubic centimeters

If f'(x) = 12x^3 - 2x^2 - 17 and f(1) = 8 , find f(x).
Cloud [144]

Answer:

f(x) =  3x⁴ - \frac{2X^{3} }{3} - 17x +  \frac{68}{3}

Step-by-step explanation:

To find f'(x), we will follow the steps below:

We will start by integrating both-side of the equation

∫f'(x) = ∫(12x^3 - 2x^2 - 17)dx

f(x)  = 3x⁴ - \frac{2X^{3} }{3} - 17x + C

Then we go ahead and find C

f(1) = 8

so we will replace x by 1 in the above equation and solve for c

f(1)  = 3(1)⁴ - \frac{2(1)^{3} }{3} - 17(1) + C

8 = 3 - \frac{2}{3} - 17 + C

C =8 - 3 + 17 + \frac{2}{3}

C = 22 +  \frac{2}{3}

C =\frac{66 + 2}{3}

C = \frac{68}{3}

f(x) =  3x⁴ - \frac{2X^{3} }{3} - 17x +  \frac{68}{3}
