1. By what factor did the medicine decrease in the first hour and a half? Explain how you know.

Answer:

Therefore, option A,B and C cannot be the angles of triangles.

Step-by-step explanation:

Given that total angles in a triangle is 180° so you have to add up all the angles :

Option A,

45° + 45° + 45° = 135° (Not a triangle)

Option B,

60° + 75° + 35° = 170° (Not a triangle)

Option C,

60.5° + 59.5° + 59° = 179° (Not a triangle)

Option C,

65° + 60° + 55° = 180° (It is triangle)

Answer:

They have no relation, except for the fact that they intersect. If the equations were instead y = +5/4x - 1/2 and y = -4/5x + 2, or y = +4/5 + 2 and y = -5/4x -1/2, then they would be perpendicular.

Option 3 is the right answer.

Step-by-step explanation:

For the given lines y = -4/5x+2 and y = -5/4x - 1/2

we have to identify whether lines are parallel or perpendicular.

As we know if two lines are perpendicular then gradients of two lines will in the form of

m1 m2=(-1)

and if the lines are parallel then the gradients of the lines will be same.

m1=m2

Here m1 = -4/5 and m2 = -5/4

Therefore

m1m2=(-4/5)(-5/4)=(+1)

and  

m1≠m2

So both the lines are neither parallel nor perpendicular to each other.

Option 3 is the right answer.

Answer:

Answer:

2 ducks and 8 goats

Step-by-step explanation:

let goat be g

let duck be d

d + g = 10

ducks have 2 legs, 2d

goats have 4 legs, 4g

2d + 4g = 36

making d the subject in the first equation;

d = 10 - g

put in second equation

2(10 - g) + 4g = 36

20 -2g + 4g = 36

2g = 36 - 20

2g = 16

g = 8

if g is 8

d = 10 - 8

d = 2

Answer:

n = 2

Step-by-step explanation:

sin 30° = ½

tan 45° = 1

then

sin 30° : tan 45° = 1 : n

½ : 1 = 1 : n

n = 2

The value of n for the trigonometric expression will be n = 2

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that the ratio sin 30°: tan 45º can be written in form 1: n. The value of n will be calculated as:-

sin 30° = ½

tan 45° = 1

Then,

sin 30° : tan 45° = 1 : n

½ : 1 = 1 : n

n = 2

Answer:

Number of red beads = 6

Number of blue beads = 15

Step-by-step explanation:

Number of total beads = 21

Ratio of red beads to the blue beads = 2 : 5

Therefore, number of red beads I have = [tex]\frac{2}{2+5}(\text{Total number of beads})[/tex]

                                                                  = [tex]\frac{2}{7}\times 21[/tex]

                                                                  = 6 beads

Number of blue beads = [tex]\frac{5}{2+5}\times (21)[/tex]

                                      = [tex]\frac{5}{7}\times 21[/tex]

                                      = 15 beads

Therefore, number of red beads = 6

And number of blue beads = 15

Solve for x and you get x = 10

Answer:

x=14

Step-by-step explanation:

I can simplify the math terms ;)

So basically 6 and 8 are the lengths of the shorter sides of the triangle, the triangle has three sides and the longest side is always called the hypotenuse, the hypotenuse is the sum of the lengths of the shorter sides. So 6+8=x

6+8=14 <-- That's your answer :)

Answer:

H0 : Number of homeowners stays the same

H1: Number of homeowners increases.

Step-by-step explanation:

The hypothesis is to test if the level of home ownership rises or doesn't.

For this type of experiment,

The null hypothesis is the current level of home ownership.

The alternative hypothesis which is usually the opposite of the null is meant to challenge the claim of the Null. Hence, the null hypothesis will support the claim or hypothesis of the study, which is that the number of homeowners increases, hence, does not remain the same.

Therefore,

H0 : Number of homeowners stays the same

H1: Number of homeowners increases.

The ordered pair at this point is (3,1)

Suppose the graph is drawn on the coordinate plane.

Let the shifting be (x,y) → (x+a, y+b)

Then, add 'a' to all x coordinates of the graph's points. Add 'b' to all y coordinates of the graph's points.

The resultant set of new points will be plotted.

Given;

From origin; move to right 3units

                     move upward 1unit

Moving to right 3units;

(0,0)= (3,0)

Move upward 1unit;

(3,0)= (3,1)
