Answer 2

Answer:

∠ A = 60°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{13}{15}[/tex] , thus

∠ A = [tex]sin^{-1}[/tex] ( [tex]\frac{13}{15}[/tex] ) ≈ 60°

------------------------------------------------

Using the cosine ratio in the right triangle

cosR = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RT}{RS}[/tex] = [tex]\frac{8}{10}[/tex] , thus

∠ R = [tex]cos^{-1}[/tex] ( [tex]\frac{8}{10}[/tex] ) ≈ 36.9° ( to 1 dec. places )

Step-by-step explanation:

[tex]P=53\text{ft}[/tex]

[tex]P = a+b+c[/tex]

[tex]53=2x-15+x+1+3x-29[/tex]

[tex]53=6x-43[/tex]

[tex]96=6x[/tex]

[tex]x=16[/tex]

[tex]a=2x-15[/tex]

[tex]a=2(16)-15[/tex]

[tex]\boxed{a=17}[/tex]

[tex]b=x+1[/tex]

[tex]b=16+1[/tex]

[tex]\boxed{b=17}[/tex]

[tex]c=3x-29[/tex]

[tex]c=3(16)-29[/tex]

[tex]\boxed{c=19}[/tex]

Answer:

1. x=16, a=17, b=17, c=19

2. k=-2

Step-by-step explanation:

1.

We can set up an equation where all the labeled sides add up to 53, and then find x:

(2x-15)+(x+1)+(3x-29)=53

6x-43=53

6x=96

x=16

Now that we know x, we can plug it back in to the expressions of the triangles to find their side lengths:

a=2(16)-15=17

b=16+1=17

c=3(16)-29=19

2.

Reminder: the slope of a line is its change in y over its change in x. We can then set up an equation:

[tex]\frac{2-k}{k-(-3)}=4\\\frac{2-k}{k+3}=4\\2-k=4k+12\\5k=-10\\k=-2[/tex]

what is the difference between the mean and the median of the set ( 3 ,8 ,10 ,15)

Answers

Answer:

You can think of the mean being acually mean because you have to do more work. When solving for the mean you add all the answers together then divide by the amount of numbers you have. For example,  you have the numers (1, 2, 3) add them together (1+2+3) to get 6 then divide by 3 (6/3) to get a mean of two. The median is also fairly easy to remember. You line your numbers up least to greatest, left to right. and mark one off of each side at a time. If you have a even amount of numbers and reach the center, you add the two centers together then divide by to to get the median. If you have an odd amount of numbers, there should be one in the exact center left over.

Step-by-step explanation:

Mean) 3+8+10+15=36, 36/4=9 ANSWER=9

Median) 8+10=18, 18/2=9 ANSWER=9

In the case, the mean and median are the same and depending on context you could choose either method. It also helps that there is no outlyer. If there were on I would recomend finding the median.

Evaluate -8a - b if a = 10 and b = 6

Answers

The answer is -86 .....

-86 is the value of -8a-b when a = 10 and b = 6.

What is Expression?

An expression is combination of variables, numbers and operators.

The given expression is -8a-b

a and b are the variables in the given expression.

Minus is the operator of subtraction in the expression.

The value of a is given as 10 and b is 6.

Now we have to substitute the values of a and b in expression.

-8(10)-6

Eight times of ten is eighty

-80-6

Minus eighty minus six is minus eighty six.

-86

Hence, -86 is the value of -8a-b when a = 10 and b = 6.

If ∠3 and ∠4 are complementary angles, m∠3 = (x+24)°, and m∠4 = x°, then find the measures of ∠3 and ∠4.

Answers

Answer:

[tex]\huge\boxed{3 = 57 \textdegree}[/tex]

[tex]\huge\boxed{4 = 33 \textdegree}[/tex]

Step-by-step explanation:

When two angles are complementary, their angle lengths add up to 90°.

Therefore, we can make the equation

[tex](x+24) + (x) = 90[/tex]

Now we can solve for x.

[tex]2x+24=90[/tex] [tex]2x=66[/tex] [tex]x = 33[/tex]

Since the measure of ∠4 is just x°, and we know x is 33, that means ∠4 is 33°.

We also have the expression for ∠3, [tex]x+24[/tex]. Since we know x is 33, we can substitute it into the expression.

(60)x = 1, what are the possible values of x? Explain your answer.

Answers

Answer:

[tex]\frac{1}{60}[/tex]

Step-by-step explanation:

Problem:

 The possible values of x in the equation (60)x = 1;

Solution:

Such a problem like this in which the highest power of the unknown is 1 will have just one solution.

       60x  = 1

To solve this, we take the multiplicative inverse of 60;

   the multiplicative inverse of 60 = [tex]\frac{1}{60}[/tex]

   Use this inverse to multiply both sides of the expression;

         [tex]\frac{1}{60}[/tex] [tex]x[/tex]  60x  = 1 x [tex]\frac{1}{60}[/tex]

                   x  = [tex]\frac{1}{60}[/tex]

The graph shows the relationship between the time in minutes and the number of milk cartons that Machine 1 can fill. The equation y = 22x describes the rate at which Machine 2 can fill cartons where x is the number of minutes and y is the number of cartons filled. PART A What is the unit rate for each machine? PART B Which machine can fill cartons at a faster rate? How much faster?

Answers

Answer:

A. 25, 22

B. machine 1

How much faster? MACHINE 1 fills 3 more cartons per minute than MACHINE 2

Step-by-step explanation:

Machine 1's unit rate = 25 and Machine 2's unit rate = 22. Machine 1 fills cartons faster and fills 3 more cartons per minute than machine 2.

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have graph that shows the relationship between the time in minutes and the number of milk cartons that Machine 1 can fill. The equation y = 22x describes the rate at which Machine 2 can fill cartons where x is the number of minutes and y is the number of cartons filled.

The equation of the graph that shows the relationship between the time in minutes and the number of milk cartons that Machine 1 can fill is -

y = [(100 - 50)/(4 - 2)]x

y = 25x

AND

y = 22x describes the rate at which Machine 2 can fill cartons.

So, we can write -

Machine 1's unit rate = 25

Machine 2's unit rate = 22

It is easily visible that Machine 1 fills cartons faster and fills 3 more cartons per minute than machine 2.

Therefore,

Machine 1's unit rate = 25 and Machine 2's unit rate = 22. Machine 1 fills cartons faster and fills 3 more cartons per minute than machine 2.
