In triangle ABC angle a equals 72° side C equals 61 and angle B equals 16° find side a to the nearest 10th
Answers
Answer:
58.0 units
Step-by-step explanation:
In order to use the law of sines, we need to know angle C. It will be the angle that brings the total of all angles to 180°.
C = 180° -A -B = 180° -72° -16°
C = 92°
The law of sines tells us ...
a/sin(A) = c/sin(C)
a = c·sin(A)/sin(C) = 61·sin(72°)/sin(92°)
a ≈ 58.0 . . . . units

( velocity - on a graph )
Answers
Answer:
a) v_avg = k
b) 0.034 km/h
Step-by-step explanation:
a) The average velocity is given by the displacement over the time:
[tex]v_{avg}=\frac{\Delta x}{\Delta t}[/tex] (1)
Δx is the area under the line. In this case you can consider two areas. Firs, from t=0 t0 t=30 and from t=30 to t=50:
S1 = 30k
S2 = 20k/2 = 10k
Then, the total surface is:
S = S1+S2 = 50k
The average speed is:
v_avg = (50k)/(50s)= k
b) The value of k can be determined by using the expression for the total area under the line, which is the total displacement of the car S=1.7 km:
S=50k=1.7km
k=(1.7km)/(50k)=0.034km/h = 34 m/h

Answers
We have been given that in a right triangle, the measure of [tex]\theta = 43^{\circ}[/tex] and the side opposite to the measure of theta is 6.5 cm long. We are asked to find the length of adjacent side to the angle theta.
We know that tangent relates opposite side of right triangle adjacent side.
[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]
[tex]\text{tan}(43^{\circ})=\frac{6.5}{\text{Adjacent}}[/tex]
[tex]\text{Adjacent}=\frac{6.5}{\text{tan}(43^{\circ})}[/tex]
[tex]\text{Adjacent}=\frac{6.5}{0.932515086138}[/tex]
[tex]\text{Adjacent}=6.9703966[/tex]
[tex]\text{Adjacent}\approx 6.97[/tex]
Therefore, the length of adjacent side to angle theta is approximately 6.97 units.

Can someone help me with is
Answers
Answer:
It is not equivalent
Step-by-step explanation:
Because the first expression simplified is 3x with the power of 9, and the first expression simplifies to x with a power of 9.
Answer:
No, they are not equivalent.
Step-by-step explanation:
In the case of the first expression: x³ * x³ * x³, you will solve the power first, before multiplying the whole numbers.
However, in terms of the second one, you are multiplying the powers first, and then solving for the power.
Take for example, x = 2. Plug in 2 for x in the expressions given:
x³ * x³ * x³ = 2³ * 2³ * 2³ = 8 * 8 * 8 = 64 * 6 = 512
However,
2^(3 * 3 * 3) = 2^(27) = 134,217,728

The value of a certain car decreases by 16% each year. What is the 1⁄2-life of the car?
Answers
Answer:
The half life of the car is 3.98 years.
Step-by-step explanation:
The value of the car after t years is given by the following equation:
[tex]V(t) = V(0)(1-r)^{t}[/tex]
In which V(0) is the initial value and r is the constant decay rate, as a decimal.
The value of a certain car decreases by 16% each year.
This means that [tex]r = 0.16[/tex]
So
[tex]V(t) = V(0)(1-r)^{t}[/tex]
[tex]V(t) = V(0)(1-0.16)^{t}[/tex]
[tex]V(t) = V(0)(0.84)^{t}[/tex]
What is the 1⁄2-life of the car?
This is t for which V(t) = 0.5V(0). So
[tex]V(t) = V(0)(0.84)^{t}[/tex]
[tex]0.5V(0) = V(0)(0.84)^{t}[/tex]
[tex](0.84)^{t} = 0.5[/tex]
[tex]\log{(0.84)^{t}} = \log{0.5}[/tex]
[tex]t\log{0.84} = \log{0.5}[/tex]
[tex]t = \frac{\log{0.5}}{\log{0.84}}[/tex]
[tex]t = 3.98[/tex]
The half life of the car is 3.98 years.
Susan paid $240 to have her house decorated. The materials used to decorate the house coast $115, and service was charged at $5 an hour. How many hours was the house worked on?
Answers
Answer:
[tex] 240 =5x +115[/tex]
And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:
[tex] 240-115= 5x[/tex]
[tex] 125 = 5x[/tex]
And now we can divide both sides by 5 and we got:
[tex] x= 25[/tex]
So then the number of hours spent to decorate the house are 25
Step-by-step explanation:
Based on the information given we can model this function with this formula:
[tex] y = mx+b[/tex]
Where y represent the total cost paid, m the cost per hour representing the slope and x the number of hours worked and finally b the initial cost for the materials. Then our function is given by:
[tex] 240 =5x +115[/tex]
And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:
[tex] 240-115= 5x[/tex]
[tex] 125 = 5x[/tex]
And now we can divide both sides by 5 and we got:
[tex] x= 25[/tex]
So then the number of hours spent to decorate the house are 25

Answer:
a) the co-ordinates of the center are (-3,4) and the length of the radius is 10 units
Center (h,k) = (-3 ,4) and radius 'r' = 10
Step-by-step explanation:
Step(i):-
Given circle equation is
[tex]2 x^{2} +12 x+2 y^{2} -16 y-150 =0[/tex]
Dividing "2' on both sides, we get
[tex]x^{2} +6 x+ y^{2} -8 y-75 =0[/tex]
Step(ii):-
now
[tex]x^{2} +2(3x) + (3)^{2}-(3)^{2} +y^{2} -2 (4 y)+(4)^{2}-(4)^2 -75 =0[/tex]
by using (a+b)² =a²+2 a b+b²
(a-b)² =a²-2 a b+b²
[tex](x+3)^{2}-(3)^{2} +(y-4)^{2}-(4)^2 -75 =0[/tex]
[tex](x+3)^{2}-9 +(y-4)^{2}-16 -75 =0[/tex]
[tex](x+3)^{2} +(y-4)^{2}-100 =0[/tex]
[tex](x+3)^{2} +(y-4)^{2}=100[/tex]
[tex](x+3)^{2} +(y-4)^{2}=(10^2)[/tex]
by comparing
[tex](x-h)^{2} +(y-k)^{2}=(r^2)[/tex]
Final answer:-
Center (h,k) = (-3 ,4) and radius 'r' = 10

it took 4 hours to clean 10 houses, how many houses could be cleaned in 8 hours?
Answers
Answer:
3 1/2 houses
Step-by-step explanation:
To find the unit rate we must divide 4 by 10
4 hours divided by 10 house = 1/4
1/4 houses per hour
8 hours times 0.4= 3.2 houses
Answer:
20 houses
Step-by-step explanation:
Let’s make a proportion using this setup:
houses/hours=houses/hour
We know that 10 houses can be cleaned in 4 hours. We don’t know how many houses can be cleaned in 8 hours, so we can say x houses can be cleaned in 8 hours.
10 houses/4 hours= x houses/8 hours
10/4=x/8
Now we have to solve for x, by getting x by itself. Perform the opposite of what is being done to both sides.
x is being divided by 8. The opposite of division is multiplication, so multiply both sides by 8
8(10/4)=(x/8)8
8(10/4)=x
8(2.5)=x
20=x
20 houses can be cleaned in 8 hours.
Find the range, mean, media and mode for 75,60,75,100,75,75,75,95,60,65
Answers
Answer:
Range: 40
Mean: 75.5
Median (a.k.a. media): 75
Mode: 75
Step-by-step explanation:
1) Put the numbers in order
60 , 60 , 65 , 75 , 75 , 75 , 75 , 75 , 95 , 100
2) Find the range
To find the range, you subtract the largest number from the smallest number. In this case, it those are 100 and 60 respectively.
100-60 = 40 which means the range is 40.
3) Find the mean
To find the mean, you add all the numbers together and then divide that by the number of numbers. So...
60 + 60 + 65 + 75 + 75 + 75 +75 + 75 + 95 + 100 = 755
755/10 = 75.5
*You divide by 10 because there are 10 numbers*
That means your mean in 75.5.
4) Find the median (a.k.a. media)
To find the median, you must find the number that is in the middle when the numbers are in order.
In this case, we have two numbers in the middle 75 and 75. To find the median we must add these two numbers together and then divide by 2.
75 + 75 = 150
150/2 = 75
That means the median is 75.
5) Find the mode.
To find the mode, you must find the number(s) that appear the most. In this case, that would be 75 as it appears five times in this number set.
That means the mode is 75.
