How to find the angle of a non right triangle with its sides?

Answers

Essentially, you find the cos, sin, or tangeant of each angle. Take, for example, sin. It's opposite/hypotenuse, so you plug that in for an angle and find that sinx=for example, 3/4. After that, you'd find arcsin (3/4) and that's your angle!

A line has a rise of 6 and a slope of 1/20. Find the run of the line. Type a numerical answer in the space provided. If necessary, use the / key to represent a fraction bar.

Answers

y=0.05x+6

6 is the y intercept

.05 or 1/20 is the slope

Answer:

120 is the run of the line

Step-by-step explanation:

Hello, i think I can help you with this

By definition , the slope of a line is given by:

slope(m)=Δy/Δx

where m is the slope, Δy is the rise, and Δx is the run

Step 1

isolate the run (Δx)

m=Δy/Δx

m*Δx=Δy

Δx=Δy/m

step 2

pute the values into the formula

Let

Δy=6

m=1/20

Δx=Δy/m

Δx=6÷(1/20)

Δx=120

the run of the line is 120

Last year, 1300 procedures were performed on 3900 patient visits. 33% of your patient visits involved a procedure. If you are able to increase that percentage to 45%, what is the number of procedures you will do this year?

Answers

Let x = number of procedures
y = number of patient visits
n = % (in decimal form)

Note:
Percentage form = 33%
Decimal form = 0.33
Conversion factor: 1 = 100%

Considering the first statement that 33% or 0.33 is derived from dividing 1300 procedures with 3900 patient visits.Then, our working formula is x/y = n.

If we are ask to increase the percentage to 45% or 0.45, then substitute this value to n in the formula. We subsequently get,

x/y = 0.45

Assuming the patient visits remains the same and substitute it in the formula. We subsequently get,

x/3900 = 0.45

Solving for x. We arrive at an answer of x = 1755 procedures.

One day a store sold 21 sweatshirts. white ones cost $9.95 and yellow ones cost $ 11.50. in all, $235.30 worth of sweatshirts were sold. how many of each color were sold?

Answers

For this problem you have yo set up two equations.

White shirts = w Yellow shirts = y

1st: w + y = 21
2nd: 9.95w + 11.50y = 235.30

Now we're going to do system of equations using substitution.

If w + y = 21, then y = 21 - w
If y = 21 - w, then you can substitute this in the second equation for y.

9.95w + 11.50(21 - w) = 235.30
9.95w + 241.5 - 11.50w = 235.30
-1.55w + 241.5 = 235.30
-1.55w = -6.2
w = 4, so 4 whites shirt were sold.

Now I'm finding out how many yellow shirts were sold using one of the two equations at the top.

w + y = 21
4 + y = 21
y = 17

So 17 yellow shirts were sold and 4 white shirts were sold.

Darrel is currently 20 feet below sea level. which correctly describes the opposite of darrel's elevation?

Answers

Answer:

Darrel is 20 ft above sea level.

Step-by-step explanation:

We have been given that Darrel is currently 20 feet below sea level.

This means that Darrel's elevation would be [tex]-20[/tex] ft.

The opposite of Darrel's elevation would be negative of [tex]-20[/tex] ft.

[tex]-(-20)=20[/tex]

Since opposite of Darrel's current elevation is positive 20 ft, therefore, Darrel is 20 ft above sea level.

In the circle shown below T is the center of the circle, and segments PN and SQ are diameters, and segment PR is tangent to the circle. The measure of angle SQN is 66 degrees

33 degrees
42 degrees
66 degrees
48 degrees

Answers

Angle SQN = 66 degrees (given)
----------------------------
Use the inscribed angle theorem to get

Minor Arc SN = 2*(angle SQN)
Minor Arc SN = 2*(66)
Minor Arc SN = 132 degrees
----------------------------
Arc PSN is a semicircle so it is 180 degrees, meaning that...

Arc PSN = (minor arc PS) + (minor arc SN)
180 degrees = (minor arc PS) + (132 degrees)
180 = (minor arc PS) + 132
180 - 132 = (minor arc PS) + 132 - 132
48 = minor arc PS
minor arc PS = 48 degrees
central angle RTP = minor arc PS = 48 degrees
----------------------------
Focus on triangle PTR; isolate angle PRT

(angle TPR) + (angle PRT) + (angle RTP) = 180
(90) + (angle PRT) + (48) = 180
(90+48) + (angle PRT) = 180
138 + (angle PRT) = 180
138 + (angle PRT) - 138 = 180 - 138
angle PRT = 42 degrees
----------------------------
----------------------------
Final Answer:
The measure of angle PRT is 42 degrees

What are the intercepts of 5x = 2y +4??

Answers

The y intercepts are when x=0 (the line crosses the y axis) and the x intercepts are when y=0 (the line crosses the x axis). Plugging x=0 in, we get 5*0=2y+4. Subtracting 4 from both sides, we get -4=2y and by dividing both sides by 2 we get y=-2, for one intercept to be (0, -2). For the other intercept, we make y=0 to get 5x=2*0+4=4. Dividing both sides by 4, we get x=4/5, making our other intercept (4/5, 0)

Answers

the third one........hope this helps

Answer:

The correct equation that applies the distributive property is:

[tex]\[ -2.5 \cdot (4 \cdot 3.67) = (-2.5 \cdot 4) \cdot 3.67 \][/tex]

Explanation:

The distributive property states that for any real numbers [tex]$ a $, $ b $, and $ c $:[/tex]

[tex]\[ a \cdot (b + c) = a \cdot b + a \cdot c \][/tex]

Let's see which equation correctly applies the distributive property:

1. [tex]$ 2.4 \cdot (-3.4) \cdot (-1.25) = (-3.4) \cdot 2.4 \cdot (-1.25) $[/tex]

This equation doesn't correctly apply the distributive property. It just switches the order of multiplication, which doesn't demonstrate the distributive property.

2. [tex]$ -2.5 \cdot (4 \cdot 3.67) = (-2.5 \cdot 4) \cdot 3.67 $[/tex]

This equation correctly applies the distributive property. It breaks down the multiplication of [tex]$ -2.5 $ and $ (4 \cdot 3.67) $[/tex] into two separate multiplications.

3. [tex]$ (42 \cdot 3.5) + (42 \cdot 1.3) + (42 \cdot 5.2) = 42 + (3.5 + 1.3 + 5.2) $[/tex]

This equation doesn't apply the distributive property. It simply adds the products on the left side and compares it to the sum of the terms on the right side, which doesn't demonstrate the distributive property.

4. [tex]$ -3 \cdot (6.48) = (-3 \cdot 6) + (-3 \cdot 0.4) + (-3 \cdot 0.08) $[/tex]

This equation correctly applies the distributive property. It breaks down the multiplication of $ -3 $ and $ 6.48 $ into three separate multiplications.

So, the correct equation that applies the distributive property is:

[tex]\[ -2.5 \cdot (4 \cdot 3.67) = (-2.5 \cdot 4) \cdot 3.67 \][/tex]

A rectangular auditorium seats 1564 people. the number of seats in each row exceeds the number of rows by 1212. find the number of seats in each row.

Answers

We can safely assume that 1212 is a misprint and the number of seats in a row exceeds the number of rows by 12. Let r = # of rows and s = # of seats in a row. Then, the total # of seats is T = r x s = r x ( r + 12), since s is 12 more than the # of rows. Then r x (r + 12) = 1564 or r**2 + 12*r - 1564 = 0, which is a quadratic equation. The general solution of a quadratic equation is: x = (-b +or- square-root( b**2 - 4ac))/2a In our case, a = 1, b = +12 and c = -1564, so x = (-12 +or- square-root( 12*12 - 4*1*(-1564) ) ) / 2*1 = (-12 +or- square-root( 144 + 6256 ) ) / 2 = (-12 +or- square-root( 6400 ) ) / 2 = (-12 +or- 80) / 2 = 34 or - 46 We ignore -46 since negative rows are not possible, and have: rows = 34 and seats per row = 34 + 12 = 46 as a check 34 x 46 = 1564 = total seats

The length of a rectangle is 3 more than 4timesthe width . If the length of the rectangle is 27 feet what is the width

Answers

To answer this question, you need to translate the description into a formula. The formula that can be made should be: length of rectangle= 3+ (4* rectangle width). You already know the length, so you can find the width by inserting it to the formula. The calculation would be:

Length= 3+ 4*width
27ft= 3ft+ 4*width
4*width= 27ft-3ft= 24ft
width= 6ft

What is a line segment?

A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.

Given that the segment EG is 50 and the ratio of EF to EG is 2 to 5. The length of the segment EF and FG will be calculated as,

EF / EG = 2 /5

EF = ( 2 x EG ) / 5

EF = ( 2 x 50 ) / 5

EF = 2 x 10

EF = 20

The length of the segment FG will be calculated as,

EF / FG = 2 / 3

FG = ( 3 x EF ) / 2

FG = ( 3 x 20 ) / 2

Fg = 3 x 10

FG = 30

How can I factor 5r^2+23r+26

Answers

use quatratic formula

Answer:the factors are r= -2 or r= -2.6

Step-by-step explanation:

5r^2+23r+26=0

The equation cannot factorized

So the general formula would be used

r = [-b +-√(b^2 -4ac)]/2a

a = 5

b =23

c = 26

r =[ -23+-√(23^2-4×5×26)]/2×5

= [-23+-√529-520)]/10

=(-23+-√9)/10

=(-23+-3)/10

r = (-23+3)/10 or r= (-23-3)/10

r= -20/10 or r= -26/10

r= -2 or r= -2.6
