In OPQ, the measure of Q=90°, OP = 96 feet, and PQ = 23 feet. Find the measure

of 20 to the nearest degree.

Answers

Answer:

[tex]O = 14^\circ[/tex]

Step-by-step explanation:

Given

[tex]\angle Q = 90[/tex]

[tex]OP = 96[/tex]

[tex]PQ = 23[/tex]

Required

Find [tex]\angle O[/tex] to the nearest degree

To calculate O, we make use of:

[tex]sin(O) = \frac{PQ}{PO}[/tex] --- See attachment for triangle

[tex]sin(O) = \frac{23}{96}[/tex]

[tex]sin(O) = 0.2396[/tex]

Take arcsin of both sides

[tex]O = sin^{-1}(0.2396)[/tex]

[tex]O = 14^\circ[/tex] -- approximated

The ratio of boys to girls taking geometry this year is 27:31. If 246 students are ebrolled in geometry this year, approximately how many of them are boys and how many of them are girls?

Answers

Answer:

115 boys

131 girls

Step-by-step explanation:

Given data

The given ratio= 27:31

The sum of the ratio = 27+31= 58

The total number of students taking geometry= 246

Let us apply the part to all method

let the number of boys be x

27/58= x/246

cross multiply

58*x= 246*27

58x=6642

x= 6642/58

x=114.5

Hence the number of boys is 115

Thefore, the number of girsl= 246-115= 131

what is the distance

Answers

Answer:

A) 10 units

Step-by-step explanation:

distance formula:

d=the square root of (x2-x1)^2 + (y2-y1)^2

(-5,4)

(3,-2)

d=the square root of (3-[-5])^2 + (-2-4)^2

d=the square root of 64+36

d=the square root of 100

d=10

What is the equation of a circle with the center (2,3) that passes through the point (5,3)

Answers

I don’t understand your question, can you go into more detail please

The given center and point on the circle of (2, 3), and (5, 3), respectively

gives the equation of the circle as; [tex]\underline{(x - 2)^2 + (y - 3)^2 = 3^2}[/tex].

How can the equation of the circle be found?

The general form of the equation of the circle is presented as follows;

(x - h)² + (y - k)² = r²

Where;

(h, k) = The center of the circle

r = The radius of the circle

Which gives;

(h, k) = (2, 3)

h = 2

k = 3

r = √((5 - 2)² + (3 - 3)²) = 3

The equation of the circle is therefore;

[tex]\underline{(x - 2)^2 + (y - 3)^2 = 3^2}[/tex]

It has a rate of 8.5 since 17/2=8.5

at the rate of 8.5 y per one x then 4 8.5's would make 34

To make the graph put a dot at
(1, 8.5)
Because...

It’s true since it goes though the origin
B)

B is true
C)
In b, we identified the slope so this can’t be true
D)

It states x=17 and y=2
So...
Y=8.5(17
Y.>2
D is not true
E)

Answers

Answer:

D

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = [tex]\frac{1}{3}[/tex] πr²h ( r is the radius and h the height )

Here V = 226 and r = 12 ÷ 2 = 6 , then

[tex]\frac{1}{3}[/tex]π × 6²h = 226 ( multiply both sides by 3 to clear the fraction )

3.14 × 36h = 678

113.04h = 678 ( divide both sides by 113.04 )

h = [tex]\frac{678}{113.04}[/tex] ≈ 6 m ( to the nearest metre )
