If XY Is 4 M And WZ Is 9 M, The Exact Volume Of The Cone Is ___ Square Meters.

Answers

Answer 1

Answer:

[tex] 48\pi \: {m}^{3} [/tex]

Step-by-step explanation:

Radius of the cone (r) = XY = 4 m

Height of the cone (h) = WZ = 9 m

[tex]V_{cone} = \frac{1}{3} \pi {r}^{2}h \\ \\ = \frac{1}{ \cancel3} \pi {(4)}^{2}( \cancel9) \: \: \red{ \bold 3 }\\ \\= \pi \times 16 \times 3 \\ \\\purple {\bold {V_{cone} = 48\pi \: {m}^{3}}} [/tex]

A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,
and (6q – 9) centimeters. Which expression represents the perimeter, in
centimeters, of the triangle?

Answers

Given:

A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,

and (6q – 9) centimeters.

To find:

The expression that represents the perimeter, in centimeters, of the triangle.

Solution:

We know that, perimeter of a triangle is the sum of its all sides.

[tex]Perimeter=(6p-7)+(7p-2)+(6q-9)[/tex]

Combining like terms, we get

[tex]Perimeter=(6p+7p)+6q+(-7-2-9)[/tex]

[tex]Perimeter=(13p)+6q+(-18)[/tex]

[tex]Perimeter=13p+6q-18[/tex]

Therefore, the perimeter of the triangle is represented by the expression [tex]13p+6q-18[/tex] centimeters.

You want to buy 7 tickets at that same rate. Explain the mathematical process you used to determine the cost of 7 tickets. (Include the unit rate in your explanation)

Answers

Answer:

Hence, the cost of the 7 tickets is :

Quantity * rate

7 * x = 7x

∠7 = 85°

Step-by-step explanation:

∠1 = 180 - 115 = 65°              Because they are supplementary angles

∠2 = 180 - 65 - 85 = 30°      Because the sum of all interior angles in a triangle
