Find The Missing Side. Round To The Nearest Tenth.

Answers

Answer 1

Step-by-step explanation:

1. have info for adjacent side and hypotenuse

so use; cosine

cos32=x/19

x=cos32×19

=15.9

2. have info for opposite side and hypotenuse

so use; sine

sin63=16/x

x=16/sin63

=95.6

3. have info for opposite side and adjacent side

so use; tangent

tan26=17/x

x=17/tan26

=14.4

4. have info for opposite side and adjacent side

so use tangent

tan42= x/13

x=tan42×13

x=29.8

Write the slope-intercept form of the equation of the line described.
Through (-2, -1) and parallel to y=-2x-1

Answers

Answer:

y= -2x -5

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept.

Parallel lines have the same slope.

Thus, to find the value of the slope of the line, we have to find the slope of the given line.

y= -2x -1

Since the coefficient of x is -2 and the equation is already in slope-intercept form, the slope of the given line is -2.

Substitute m= -2 into the equation:

y= -2x +c

To find the value of c, substitute a pair of coordinates.

When x= -2, y= -1,

-1= -2(-2) +c

-1= 4 +c

c= -1 -4 (-4 on both sides)

c= -5

Thus, the equation of the line is y= -2x -5.

what is Evaluate 4/5-3/7​

Answers

Answer:

[tex] \frac{13}{35} [/tex]

Step-by-step explanation:

To add or subtract two or more fractions from each other, the denominators have to be the same. To make the denominators the same, we should find the least common multiple of 5 and 7. The least common multiple of 5 and 7 is 35. 5 should be multiplied with 7 to get 35 and 7 should be multiplied with 5 to get 35 (with both numerators).

[tex] \frac{4}{5 } - \frac{3}{7} [/tex]

[tex] \frac{4 \times 7}{5 \times 7} - \frac{3 \times 5}{7 \times 5} [/tex]

[tex] \frac{28}{35} - \frac{15}{35} [/tex]

[tex] \frac{13 }{35} [/tex]

When subtracting, only subtract the numerators (the denominators are kept as is).

Old Man Withers just died. He left his collection of baseball cards to his two sons. Bill got 55% of the collection and his brother Bob received the rest.

How many cards did Bill receive if Bob received
360 cards, then how many cards did Bill as inheritance from his father?

Answers

Answer:

Step-by-step explanation:

Bill = 55% of the entire collection

Bob = 45% of the entire collection (Since we know 100 - 55 = 45)

We are also told that Bob received 360 cards.

This means that 45% = 360 cards.

First step is to find how many cards is 1%. To do this, divide 360 by 45.

1% of entire collection = [tex]\frac{360}{45} = 8[/tex] cards

This means that since Bill gets 55% of the entire collection, you multiply 8 by 55.

Bill = 8 x 55 = 440 cards.

Answer:

1) A = 80

2) A = 30

Step-by-step explanation:

1) x+50 + 80 + x + 70 = 180

2x+120 = 180

2x = 60

x=30

A = (30) + 50

A = 80

2) x+40 + x+90 + (180-110) = 180

x+40 + x+90 + 70 = 180

2x + 200 = 180

2x = -20

x = -10

A = (-10) + 40

A = 30

Answer:

x = [tex]\frac{5}{3}[/tex]  or [tex]1 \frac{2}{3}[/tex]

Step-by-step explanation:

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

~

Step 1:

Subtract 4 from both sides of the equation:

4 (-4) - 3x = -1 (-4)

-3x = -1 - 4

-3x = - 5

Step 2:

Divide -3 from both sides of the equation:

(-3x)/-3 = (-5)/-3

x = -5/-3

x = 5/3

x = 1 2/3

Two trains are traveling at constant speeds on different tracks.

Answers

Answer:

Train B is traveling faster

Step-by-step explanation:

From the picture, we want to know which train is traveling faster

We can know this by knowing the speed of the trains

Mathematically;

speed = distance/time

Train A

12.5 m in 1 second

speed = 12.5/1 = 12.5 m/s

Train B

100 m in 4 seconds

speed = 100/4 = 25 m/s

So train B is traveling faster

This is because it covered a distance of 100 m in 4 seconds as opposed to train A which covered a distance of 12.5 m

in 1 second

Express this number in standard form.

What is the slope of a line perpendicular to the line whose equation is
12x – 3y = 81. Fully reduce your answer.

Answers

Answer:

slope of perpendicular line is -1/4

Step-by-step explanation:

slope of standard equation of line that is ax+ by = c is

slope m = -a/b

given equation is

12x – 3y = 81

comparing it with ax+ by = c

a = 12

b = -3

thus

slope of given line = -12/-3 = 4

we also know product of slope of two perpendicular line is -1

let the slope of other line be m

thus,

product of given line line and perpendicular line is -1

4*m = -1

m = -1/4

Thus,

slope of perpendicular line is -1/4

Answer:

A. 1.88

Step-by-step explanation:

In less fancy terms, a constant of proportionality is essentially a rate of change - or more specifically, a unit rate.

It's the number we multiply our independent variable by to get the y. You can find this by simply dividing the y value by the x value!

Let's choose the first order pair (2, 3.76).

[tex]3.76 \div 2 = 1.88[/tex]

We can check that this table IS constant by doing the same with the other values... we should always get 1.88!

[tex]7.52 \div 4 = 1.88\\9.40 \div 5 = 1.88\\15.04 \div 8 = 1.88[/tex]

This is true for all values - which means our constant is 1.88
