Answer:

[tex]5\sqrt{3}[/tex]

Step-by-step explanation:

A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:

The side opposite the 30* angle = a

The side opposite the 60* angle = [tex]a\sqrt{3}[/tex]

The side opposite the 90* angle = 2a

(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")

They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:

Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.

Once we know what "a" is, we can fill in the rest:

30* = 5

60* = [tex]5\sqrt{3}[/tex]

90* = 10

a straight angle measures up to 180 so

62+(6d+4)=180

62+6d+4=180

66+6d=180

6d=180-66

6d=114

d=114/6

d=19

To find:

The quotient of the given fraction value.

Solution:

We have,

[tex]\dfrac{7^{-1}}{7^{-2}}[/tex]

It can be written as:

[tex]\dfrac{7^{-1}}{7^{-2}}=7^{-1-(-2)}[/tex]            [tex]\left[\because \dfrac{a^m}{a^n}=a^{m-n}\right][/tex]

[tex]\dfrac{7^{-1}}{7^{-2}}=7^{-1+2}[/tex]

[tex]\dfrac{7^{-1}}{7^{-2}}=7^{1}[/tex]

[tex]\dfrac{7^{-1}}{7^{-2}}=7[/tex]

Therefore, the value of the quotient is 7.

What is the volume of a right circular cone that has a height of 19 feet in a base with a diameter of 18.7 feet round your answer to the nearest 10th of a cubic foot

Answers

Answer:

A = 1739.4 cubic feet

Step-by-step explanation:

B = area of base (πr²)

h = height

A = Bh/3

A = [(18.7÷2)²π × 19] / 3

A = (9.35²π×19) / 3

A = 1739.4

Use the table to write a linear function that relates y to x.

Answers

Answer:

y=(3/2)x+5

Step-by-step explanation:

Sketch it out real quick on a piece of paper.

As you can tell from the table, for every 3 units along the x axis, 2 units upwards are taken along the y axis.

This makes the slope of the equation (3/2)x or (1  1/2)x

The y-intercept is at y=5 because (on the table), when x=0, y=5.

This makes the equation in point-slope form y=(3/2)x+5

A choir teacher is dividing 12 sopranos and 9 altos into singing groups. He wants each group to have the same combination of sopranos and altos, with no singers left over. What is the greatest number of groups he can make?

Answers

Answer:

3 groups

Step-by-step explanation:

Sopranos = 12

Altos = 9

Find the highest common factor of 12 and 9

12 = 1, 2, 3, 4, 6, 12

9 = 1, 3, 9

The highest common factor of 12 and 9 is 3

Therefore, the choir teacher can only have 3 groups

12 sopranos / 3 groups

= 4 sopranos per group

9 Altos / 3 groups

= 3 altos per group

Each of the 3 groups Will have 4 sopranos and 3 altos each
