At the sewing store, Whitney bought a bag of mixed buttons. She got 90 buttons in all. 27 of the buttons were large. What percen

ANEK [815]

If I'm correct the answer is 30%. I think it is 30% because if you divide 27 by 90 it equals 0.3 which is 30%

Answer:

$Volume=207.24 mm^{3}$

Step-by-step explanation:

Given:

From the given figure.

Cone height = 7 mm

Cylinder height = 5 mm

Base radius of the cylinder = base radius of the cone = 3 mm

The volume of the given figure is

Volume = volume of cylinder + volume of cone-----------(1)

The volume cylinder is.

$V = \pi r^{2} h$ ----------(2)

Where: r = radius of the cylinder, h = height of the cylinder.

Put the value of height and radius of the cylinder in equation 2.

$V = 3.14\times 3^{2}\times 5$

$V = 3.14\times 9\times 5$

$V = 141.0\ mm^{3}$

The volume of the cylnder is $141.3 mm^{3}$

The volume cone is.

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

Where: r = base radius of the cone, h = height of the cone.

Put the value of height and base radius of the cone in equation 3.

$V = 3.14\times 3^{2}\times \frac{7}{3}$

$V = 3.14\times 9\times \frac{7}{3}$

$V = 3.14\times 3\times 7$

$V = 65.94\ mm^{3}$

The volume of the cone is $65.94 mm^{3}$ .

Put the value of the volume of cone and cylinder in equation 1.

$Volume=141.3+65.94$

$Volume=207.24 mm^{3}$

Therefore, the volume of the given figure is $207.24 mm^{3}$

Answer:

$36\:\text{units}$

Step-by-step explanation:

Drop a height directly through the middle of the triangle, intersecting the base at a 90 degree angle. We form two right triangles and can use the Pythagorean theorem to solve for the hypotenuse.

The Pythagorean theorem states that for any right triangle, the following is true:

$a^2+b^2=c^2$ , where $a$ and $b$ are two legs of the triangle and $c$ is the hypotenuse.

Therefore, we have the following equation (using the graph to measure the length of the two legs):

$5^2+12^2=x^2,\\x^2=169,\\x=13$

The other "tilted" side must be the same length. The base of the triangle can be measured using the graph - 10 units.

Therefore, the perimeter is $10+13+13=\boxed{36\:\text{units}}$
