What The length of AC?

What The Length Of AC?

Answers

Answer 1
If Angle C is 53° then angle A=42°

sin 42°/85=sin 85°/AC
==>AC=sin 85° *85 /sin 42°=126.54711....
Answer 2
A= 42 ° . 180- 138= 42. You get 138 from adding the angles given together (85+53)

Assume that the set s has 8 elements. how many subsets of s have at most 2 elements?

Answers

C(n,k) = n! / k! (n - k)! = number of k-combinations from a set of n elements. 

The subsets of S that have 0, 1 or 2 elements include C(11,0) empty set, (C11,1) 1-element sets and (C11,2) 2-element sets. 

C(11,0) = 11! / 0! 11! = 11! / 1×11! = 1 
C(11,1) = 11! / 1! 10! = 10!×11 / 1×10! = 11 
C(11,2) = 11! / 2! 9! = 9!×10×11 / 2×9! = 10×11/2 = 55 

The total number of subsets of S that have at most 2 elements is 
1 + 11 + 55 = 67

S is between T and V. R is between S and T. T is between R and Q. QV=18, QT=6, and TR=RS=SV. Find RS , QS , TS , and TV.

Answers


                                             4                     4               4
-----Q-----------------------T----------------R---------------S---------------V
      <----------6----------->
      <-----------------------------------------18--------------------------------->


QT = 6 (given)
QV = 18 (given)
TR=RS=SV (given)

Then TV = 18-6 = 12 and since TR=RS=SV , then each segment = 12/3 =4

RS = 4
QS = 14
TS =  8
and TV. = 12

A line can have as many points as possible, and multiple lines can have similar points. The values of RS, QS, TS and TV are:

[tex]RS = 4\\QS =14\\TV = 12\\TS = 8[/tex]  

S is a point between lines T and V means:

[tex]TV = TS + SV[/tex]

R is a point between lines S and T means:

[tex]TS = RS + TR[/tex]

T is a point between lines R and Q means

[tex]RQ = TR + QT[/tex]

Given that:

[tex]QT = 6\\QV = 18[/tex]

This means that Q is a point between lines QT and QV. So:

[tex]TV = QV - QT[/tex]

[tex]TV = 18- 6[/tex]

[tex]TV = 12[/tex]

[tex]TR=RS=SV[/tex] means that:

[tex]TV = TR+RS+SV[/tex]

Because [tex]TR=RS=SV[/tex], the equation becomes:

[tex]TV = TR+TR+TR[/tex]

[tex]TV = 3TR[/tex]

Substitute 12 for TV

[tex]12 = 3TR[/tex]

Divide both sides by 3

[tex]4 = TR[/tex]

[tex]TR =4[/tex]

Hence:

[tex]TR=RS=SV=4[/tex]

[tex]TS = RS + TR[/tex] gives

[tex]TS = 4 + 4[/tex]

[tex]TS = 8[/tex]

Next, we calculate the measure of QS from lines QV and SV

Point S is common between QS and SV. This means:

[tex]QV = QS + SV[/tex]

Make QS the subject

[tex]QS =QV -SV[/tex]

[tex]QS =18-4[/tex]

[tex]QS =14[/tex]

Hence, the values of RS, QS, TS and TV are:

[tex]RS = 4\\QS =14\\TV = 12\\TS = 8[/tex]

If tap and bre are supplementary and bre is its own complement, find the measure of tap. explain how you arrived at your answer

Answers

Supplementary angles are those whose sum is equal to 180° while those that are complementary are those whose sum is equal to 90°. Since, we are given that bre is the complement of itself, its measure can be calculated through the equation,
                           m∠bre + m∠bre = 90°
                                   m∠bre = 45°

Then, for the relationship of bre and tap, we have the equation,
                       m∠bre + m∠tap = 180°
                        45° + m∠tap = 180°
                                m∠tap = 135°

The measure of tap is equal to 135°.

Pauley graphs the change in temperature of a glass of hot tea over time. He sees that the function appears to decrease quickly at first, then decrease more slowly as time passes. Which best describes this function? It is linear because the graph decreases over time. It is linear because there is both an independent and a dependent variable. It is nonlinear because linear functions are increasing functions. It is nonlinear because linear functions increase or decrease at the same rate.

Answers

Answer:

It is nonlinear because linear functions increase or decrease at the same rate.

Step-by-step explanation:

A linear function is a function with a constant rate of change.  This means it increases or decreases at the same rate.

Since this function decreases quickly and then more slowly, it does not have a constant rate of change; it is not linear.

Given the system of equations, what is the solution?
x + 2y = 7
x - 2y = -1

(A.) {(-8, -12)}
(B.) {(3, 2)}
(C.) {(-4, 6)}

Answers

We can do the elimination method to find the solution for this problem. The elimination method involves adding the two equations together to get rid of a like term.

x + 2y = 7
+ x - 2y = -1
—————————
2x = 6

Now that we eliminated 2y because they cancel out, we are left with 2x = 6. Divide both sides by 2 in order to get x.

The answer is: x = 3.

Now that we know the numerical value of x, all we have to do is plug x into either system of equation in order to find the numerical value of y.

x + 2y = 7

3 + 2y = 7

2y = 4

y = 2

The solution to the problem is (3, 2).

Final answer:

The solution to the system of equations x + 2y = 7 and x - 2y = -1 is found by eliminating y, yielding x=3 and y=2, which is option B, (3, 2).

Explanation:

The solution to the system of equations x + 2y = 7 and x - 2y = -1 can be found by adding or subtracting the two equations to eliminate one of the variables. By adding the two equations, we eliminate y and get 2x = 6, which results in x = 3. Substituting x = 3 back into either of the original equations yields y = 2. Therefore, the solution to the system is (3, 2), which corresponds to option B.

A cab charges 1.45 for the flat fee and 0.55 for each mile. Write and solve an inequality to determine how many miles Ariel can travel if she has 35 dollars to spend

Answers

m = mile

subtract 1.45

.55m = 33.55

m = 61 miles or less
y>ax+b

b: A cab charges 1.45 for the flat fee
a: and 0.55 for each mile
x: miles she can travel
y: total money she has (35$)

so: 35>0.55 x + 1.45

solve for x:

0.55 x < 35 - 1.45

A rectangular box is to have a square base and a volume of 80 ft3. the material for the base costs 45¢/ft2, the material for the sides costs 10¢/ft2, and the material for the top costs 28¢/ft2. letting x denote the length of one side of the base, find a function in the variable x giving the cost (in dollars) of constructing the box.

Answers

The volume of a rectangular box is equal to the area of its base times the vertical height. Thus,

V = Ah = 80

Since the base is a square with side x, then the area is equal to x². Hence, we can express h in terms of x.

80 = x²h
h = 80/x²

Now, each lateral side of the rectangular box is in the shape of a rectangle with a length of h and a width of w. Hence, the equation for the total cost would be:

Total Cost = Cost per area of lower base + Cost per area of upper base + 4(Cost per area of lateral side)
Total Cost = 0.45x² + 0.28x² + 4(0.10h*x)
Total Cost = 0.73x² + 0.4hx
Since h = 80/x²,
Total Cost = 0.73x² + 0.4(80/x²)(x)
Total Cost ($) = 0.73x² +32/x

Math quest after a winter storm, the depth of the snow on cherry street was 10 \text{ cm}10 cm10, space, c, m. but then, the snow started melting at a rate of \dfrac{1}{3} \text{ cm}​3​​1​​ cmstart fraction, 1, divided by, 3, end fraction, space, c, m per hour.what was the depth of the snow on cherry street after 333 hours?

Answers

We are given that the initial depth of snow is 10 cm while the rate of melting is 1/3 cm per hour. So the melted ice after 3 hours is:

melted = (1/3 cm/hr) * 3 hours = 1 cm

 

Hence the depth left is:

depth = 10 cm – 1 cm = 9 cm

 

Answer:

9 cm

Answer:

9 cm.

Step-by-step explanation:

Let x be the number of hours.

We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of [tex]\frac{1}{3}[/tex], so the snow melted in x hours will be [tex]\frac{1}{3}x[/tex].

Since initially there was 10 cm of snow, so the depth of snow after x hours will be:

[tex]10-\frac{1}{3}x[/tex]

To find the depth of snow after 3 hours we will substitute [tex]x=3[/tex] in our expression.

[tex]10-\frac{1}{3}\times 3[/tex]

[tex]10-1[/tex]

[tex]9[/tex]

Therefore, the depth of the snow on cherry street after 3 hours will be 9 cm.
