8 0

Answer:

4 3/4

Step-by-step explanation:

= (8 - 3) + (1/4 - 1/2)

= 5 + 1/4 - (1 x 2 over 2 x 2)

= 5 + 1/4 - 2/4

= 5 and (1/2 over 4)

= 5 + -1/4

= 4 3/4

Answer:

$\%Guitar = 33 \%$

Step-by-step explanation:

Given

The two-way table

Required

Percentage of men and women whose favorite is Guitar

From the table, we have:

$Total = 200$

Those who prefer Guitar

$Men=29$

$Women = 37$

So:

$Guitar = 29 +37 = 66$

So, the percentage of men and women is:

$\%Guitar = \frac{Guitar}{Total} * 100\%$

$\%Guitar = \frac{66}{200} * 100\%$

$\%Guitar = \frac{6600}{200} \%$

$\%Guitar = 33 \%$

A cone that is sliced through the vertex would make the shape of a triangle.

You are told the h eight is 10 cm and the radius is 4 cm.

The radius would be half the base, so the base would be 4 * 2 =8 cm.

The area of the triangle is found by multiplying the base by the height, then dividing by two.

Area = 8 x 10 = 80

80 / 2 = 40 square centimeters.
