Find the measure of the angle, θ, where 0° ≤ θ ≤ 90°.
sinθ = 1/2

Answers

Answer:

[tex]\theta = 30^{\circ}[/tex]

Step-by-step explanation:

Given:

Range: [tex]0^{\circ} \le \theta \le 90^{\circ}[/tex]

[tex]Sin \theta = \frac{1}{2}[/tex]

Required

Find [tex]\theta[/tex]

[tex]Sin \theta = \frac{1}{2}[/tex]

Take arcsin of both sides

[tex]sin^{-1}(sin\theta) = sin^{-1}(\frac{1}{2})[/tex]

[tex]\theta = sin^{-1}(\frac{1}{2})[/tex]

Using the sin table

[tex]\theta = 30^{\circ}[/tex]

Quentin can read 18 pages of a book in 2 hours. How many pages can he read in 10 hours? PLEASE HELP ASAP FOR 17 POINTS!

Answers

Answer:

90 pages in 10 hours :)

Answer:

90 pages

Step-by-step explanation:

First, you need to find the unit rate of how many pages he can read.

So, you divide 18 pages by 2 hours = 9 pages per hour.

Then, you multiply 9*10 hours to find out how many pages he will read in 10 hours.

You get 90.

Simplify (use only positive exponents) : (3y^10)(2y^2)/8y^5

please explain how you did it so that I can understand what I'm doing <3

Answers

When multiplying variables with exponents, all you have to do is to add the exponents and that’s the ‘product.’

So;

(3y^10)(2y^2) is equal to (3)(2)(y^10+2).

6y^12/8y^5


When dividing exponents, you do the opposite and subtract the exponents. And you divide the whole number by half.


6y^12/8y^5 = 3y^7/4

your family went out to dinner to celebrate your grandmas 100th birthday. The total for the dinner was $208.60, so your parents left a $31.29 tip. What percent of the bill was the tip?

Answers

Answer:

[tex]\%Tip = 13.04\%[/tex]

Step-by-step explanation:

Given

[tex]Tip= \$31.29[/tex]

[tex]Bill = \$208.60[/tex]

Required

Determine the percentage of the tip

First, we calculate the amount paid

[tex]Amount = Tip + Bill[/tex]

[tex]Amount = \$31.29 + \$208.60[/tex]

[tex]Amount = \$239.89[/tex]

The percentage of the tip is then calculated using:

[tex]\%Tip = \frac{Tip}{Amount} * 100\%[/tex]

[tex]\%Tip = \frac{31.29}{239.89} * 100\%[/tex]

[tex]\%Tip = \frac{31.29* 100}{239.89} \%[/tex]

[tex]\%Tip = \frac{3129}{239.89} \%[/tex]

[tex]\%Tip = 13.04\%[/tex]

What number decreased by 23% is equals 123?

Answers

Answer: Lets call the number x

decreased means subtraction.  If x is decreased bt 23% then the result is

x-23%(x)  =  x-(23/100)x    or x-.23x

x-.23x=539

.77x=539

x=539/.77

x=700

check:  700-.23(700)=539

           700-161=539

4) 4x + 3y = 56
2x + y = 24
Solve using elimination please show work

Answers

Answer:

x = 8     y = 8

Step-by-step explanation:

Multiply 2nd equation by -3 to get -6x - 3y = -72

Now  4x + 3y = 56

         -6x - 3y = -72

         -2x      =  -16

            x = 8

Substitute x = 8 into the 2nd equation

2(8) + y = 24

16 + y = 24

y = 8

Check:  Substitute the values into the 1st equation

4(8) + 3(8) = 32 + 24 = 56  So we have the correct values for x and y

40%

Step-by-step explanation:

As a Fraction your answer would be [tex]\frac{48}{120}[/tex].

However we are looking for it as a percentage.

In order to calculate, this you can simply find 10%, and 5% of 120.

What is the intercept of

y=-1/2x-1 and y=1/4x-4

Answers

Answer:  The y-intercept of y = -1/2x -1  is (0,-1)

The y-intercept of y = 1/4x -4  is (0,-4)

The attachment shows the graph of these equations.

Step-by-step explanation:

Both equations are in slope-intercept form. y = mx + b

The constant, b, is the y-intercept.

The y-intercept of y = 1/2x -1  is (0,-1)

The y-intercept of y = 1/4x -4  is (0,-4)

What is y- intercept?

On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.

Given:

y=-1/2x-1 and y=1/4x-4

For Finding the y- intercept put x= 0 we get

y = -1/2(0) -1

y= 0- 1

y= -1.

For Finding the y- intercept put x= 0 we get

y=1/4(0)-4

y= 0- 4

y= -4
