a = 20; b = 10sqrt(3)

Step-by-step explanation:

The ratio of the lengths of the sides of a 30-60-90 triangle is

1 : sqrt(3) : 2

b = 10 * sqrt(3)

b = 10sqrt(3)

a = 2(10)

a = 20

Answer: a = 20; b = 10sqrt(3)

Answer:

a=20,[tex]b=10\sqrt{3}[/tex]

Step-by-step explanation:

SOH-CAH-TOA

Tan = O/A

Tan(60)= b/10

[tex]b=10\sqrt{3}[/tex]

Cos = A/H

cos(60) = 10/a

a=20

Answer:

B. [tex]\frac{450}{10000}[/tex]

Step-by-step explanation:

The probability of rolling a 2 is 10 out of 100 (18+10+12+25+3+32), or 10%.

The probability of the coin landing heads up is 45 out of 100. or 45%.

Multiply both probabilities together.

2.32 km

Step-by-step explanation:

Take the amount that Karen jogged and subtract the amount that Morgan jogged

53.52 - 51.2

2.32

Answer:

9

Step-by-step explanation:

r = 27/81 = 1/3

a = 81

Tn = 1/81

ar^(n-1) = 1/81

81(1/3)^(n-1) = 1/81

(1/3)^(n-1) = 1/6561

(1/3)^(n-1) = 1/3^(8)

Compare the exponents,

n-1 = 8

n = 9

Answer:

Step-by-step explanation:

Sum of digits of rank even - sum of digits of rank odd  must be a multiple of 11

(5+4+m+1)-(1+6+0)=11*k

10+m-7=11*k

3+m=11*k

m=8

So the angles are each 45 degrees

Answer:

the function is a y-intercept

Step-by-step explanation:

y=mx+b is the slope intercept formula, m being the slope and b being the y-intercept, meaning y=b, so b=-9/4.

Because it says y=-9/4, we can assume that m, or the slope equals 0.

so when you plug it in, you get

y=0x-9/4

y=-9/4

Answer:

Step-by-step explanation:

First one - Because it says 2 years ago, you can do 60000-4% for one year and then take the answer and - another 4% for the second year to get her income from 2 years ago. (I commented on this)

Second one - 1/3 - Take 1/6*200%=1/6*2=2/6, 2/6=1/3. So 1/3 or 2/6 of the students have a engineering major

The graph is shown in the attachment below

From the graph, the solution to the equation [tex]\frac{4}{x}-2x+1=0[/tex] is x = -1.2 and x = 1.7

From the picture, we are to draw the graph of the function

[tex]y = -\frac{4}{x}[/tex] for the range of values [tex]-3\leq x\leq 3[/tex] (that is for values of x from -3 to 3)

First we will create the table of values for the function

Table of values for the function [tex]y = -\frac{4}{x}[/tex]

x y

-3 1.33

-2 2

-1 4

0 Undefined

1 -4

2 -2

3 -1.33

(Shown better in the docx attachment)

The graph for the function [tex]y = -\frac{4}{x}[/tex]  (purple lines) is also shown in the attachment.

To use the graph to solve the equation [tex]\frac{4}{x}-2x+1=0[/tex]

We will rewrite the equation so that it takes the form [tex]y = -\frac{4}{x}[/tex]

From [tex]\frac{4}{x}-2x+1=0[/tex]

Then, [tex]-2x+1= -\frac{4}{x}[/tex]

∴ [tex]y = -2x+1[/tex]

Hence, we will plot the graph for the function [tex]y = -2x+1[/tex] on the same graph and the points of intersection gives the solution.

The function is a linear equation

The points of intersection on the x and y axes (x-intercept and y-intercept) are enough to plot a straight line graph as shown in the table below as well as in the graph

x y

0 1

0.5 0

(Shown better in the docx attachment)

The straight red lines in the graph shows the plot for the function [tex]y = -2x+1[/tex]

From the graph, the points of intersection are -1.2 and 1.7

Hence, the solution to the equation [tex]\frac{4}{x}-2x+1=0[/tex] is x= -1.2 and x = 1.7

Answer:

Step-by-step explanation:

There are two ways to do this.

Her current pay is C

Her previous pay is x

C = x + 7/100 * x

Or you could combine x and 7% of x immediately

7/100 x = 0.07x

C = 1.07 * x

Answer:

x times 107%

Step-by-step explanation:

If Mrs. Franklin received a 7% raise on x salary she would now be earning 7% more than x. To find this we can easily multiply x by 107% since she is earning 7% more than her previous salary, or x, and get our answer.

Answer:

9π meters

Step-by-step explanation:

SInce 6π is the circumference of the circle, 6π would be the diameter.

We need to then convert 6π into the radius which we can do by dividing 6π by 2 to get 3π.

The formula for the area of a circle is πr^2. Plug in the previous result for the radius to get the following:

π3^2

9π

Answer:

Area=9π m²

Step-by-step explanation:

Hi there!

We are given that the circumference of a circle is 6π meters, and we want to find the area of the circle

The formula to find the circumference of a circle is 2πr, where r is the radius

The formula to find the area of a circle is πr², where r is the radius

So we need to find the radius

As 6π and 2πr both equal the circumference of the circle, 6π is equal to 2πr. This is possible by a property known as  transitivity (if a=b and b=c, then a=c) .

As an equation, the result is:

6π=2πr

Divide both sides by 2π

3=r

So the radius is 3 meters

Now, substitute 3 as the radius in πr² to find the area

A=πr²

A=π(3)²

Raise 3 to the second power, which is the same as multiplying it by itself

A=π*9

A=9π m²

Hope this helps!
