The height of the kite will be 6.6 ft rounded to the nearest tenth.

<u><em>Explanation</em></u>

According to the below diagram, AB is the height of the kite and AC is the 12 ft line attached to it.

The line is pulled taut and casts a 10 ft shadow. That means BC = 10 ft

Now, in right angle triangle ABC, using <u>Pythagorean theorem</u>....

(AB)^2 +(BC)^2 = (AC)^2 \\ \\ (AB)^2 +(10)^2 = (12)^2 \\ \\ (AB)^2 +100 = 144\\ \\ (AB)^2 = 144-100 =44\\ \\ AB=\sqrt{44}= 6.6332....

So, the height of the kite will be 6.6 ft rounded to the nearest tenth.

➷ As there would be 2 circles, you'd need to find the area of a circle and then multiply it by 2

To start with, we can use this:

2 (\pir^2)

^^ This represents the surface area of the two circles

A cylinder also has a rectangle which is rolled to form the shape

As we know, the formula of a rectangles area is length x width

The width of the rectangle would be equal to the circumference of a circle

circumference of circle = \pi d

The length of the rectangle would be the height of the cylinder

We can use this:

(\pi d * h) + 2(\pi r^2)

This would calculate the surface area as it would find the area of the rectangle plus the area of the two circles.

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

Answer:

<h3><em>isosceles</em></h3>

An isosceles triangle is a triangle that has two sides of equal length.

An acute triangle is a triangle with three acute angles (less than 90°).

A scalene triangle has all its sides of different lengths. Equivalently, it has all angles of different measure.

An equilateral triangle is a triangle in which all three sides are equal.

Evelyn is making a candy that contains 25% dark chocolate and the rest milk chocolate. The candy has 3 pounds of milk chocolate.
Gnesinka [82]
A.
100%=all
so if 25% is dark and the rest is milk then
dark+milk=all
25%+milk=100%
minus 25% both sides
milk=75%

so
if milk chocolate=3lb then
3lb=75%
divide by 3
1lb=25%=dark chocolate
oops, I didn't use an equation
hmm



ratios and things
75%=milk
25%=dark

so we got
for m=pounds of milk chocolate
and d=dark chocolate
m/d=72/25 or m/d=3 and
m=3
duh
3/d=3
3=3d
1=d


B. 1 lb dark chocolate
