I only (sort of) know 3 and 4

3. Andle 1 is an example of an angle bigger than
${90}^{o} c$
I don't know what you call it.

4. If you have a straight line, both angles (or more) added up need to be
${180}^{o} c$
so if angle 1 is 129, 180-129=51
angle 2 is
${51}^{o} c$

If 1 is what is the relationship between the two angles, then maybe the answer is that they both added up need to be 180 degress (?)

And 2 is probably the same as 3 but with angle 2, angle two is an example of an angle smaller than 90 degrees

Volume of a cone = r²h,

inessss [21]

Answer:

7.5 m 457.5 $\pi$ $m^{2}$

Step-by-step explanation:

First, visualize the original cone and the smaller cone as overlapping similar triangles. The scale factor of the original cone to the smaller cone is 50:40, so if the smaller cone has a radius of 6 m, then the radius of the original cone would be 7.5 m.

The volume of the frustum is the volume of the original cone minus the volume of the smaller cone. The formula for the volume of a cone is V = $\frac{1}{3} \pi r^{2}h$ .

Original Cone = $\frac{1}{3} \pi r^{2}h$ = $\frac{1}{3} \pi *7.5^{2}*50$ = 937.5 $\pi$

Smaller Cone = $\frac{1}{3} \pi r^{2}h$ = $\frac{1}{3} \pi *6^{2}*40$ = 480 $\pi$

Frustum = 937.5 $\pi$ - 480 $\pi$ = 457.5 $\pi$

Since we know that 1/4 is equal to 25%, or 0.25 in decimal form, we are able to work with 0.75 in the expression.

We are told to use j as the original price of the jeans, so we can set up the expression:

$j-0.25j$

to represent the cost of the jeans with the discount.

Then to simplify, we simply take out j as a common factor, and solve what's in the parentheses:

$j(1-0.25)$

$j(0.75)$ or $0.75j$

Using this equation, we can solve for the b part of the question. If the pair of jeans originally costs $60, plug in 60 to where j is in the expression:

$0.75j$

$0.75(60)=45$
