Answer:
a. C(x(h)) = 600h + 500
b. C(8) = 5,300
c. See below.
Step-by-step explanation:
a. C(x(h)) = C(30h) = 20(30h) + 500 = 600h + 500
b. C(8) = 600(8) + 500 = 5,300
c. 5,300 is the cost of making the number of shovels that can be made in 8 hours.
A, B and C lie on a straight line.

Answer: $800 because if you have a light that is $2,000 and it loses %10 of its price per month, and June is 4 months away, then it is only $800.
4 x .1 = .4 so $2,000 x .4 = $800

Of the last 14 contestants on a game show, 7 qualified for the bonus round. Considering this data, how many of the next 10 contestants would you expect to qualify for the bonus round?
a. 7/10
b. 3/7
c. 1/2
d. 1/3
Answer:
c. 1/2
Step-by-step explanation:
7 out of 14 contestants did last time, which is 1/2 of the contestants. You would assume that the same proportion would qualify when there are 10 contestants, so you would assume that 1/2 of 10 would also qualify for the bonus round.

The answer you selected in the picture is correct
Step-by-step explanation:
where k is the constant of variation. For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5(2) = 10. ... Thus, the equation describing this inverse variation is xy = 10 or y = .
A triangle has angles measuring 35° and 90°. What is the measure of the third angle?
Answer:
55 degrees
Step-by-step explanation:
All the angles of a triangle should add up to 180 degrees.
So, if you add angles 1 and 2 together and subtract them from 180 it will result in the unknown angle.
35+ 90 + x = 180
125 + x = 180
x = 55

state true or false
0 is the multiplicative inverse of 0?
Answer:
false
Step-by-step explanation:
I say false because the multiplicative inverse of 0 is undefined and the multiplicative inverse tells us that when you multiply a number by its inverse the product will be1 think the multiplicative inverse of 0 is undefined.

Helppp law of sines and law of cosines
Answer:
[tex]\displaystyle ST ≈ 15,9\\ RT ≈ 30,8 \\ m∠S = 111°[/tex]
Step-by-step explanation:
First off, find [tex]\displaystyle m∠S:[/tex]
[tex]\displaystyle 180° = 58° + 31° + m∠S → 180° = 89° + m∠S \\ 111° = m∠S[/tex]
Now that the third angle has been defined, we can move move forward with solving for a second edge, using the Law of Sines, but before proceeding, here are some things you should know about this triangle:
Edge s [RT] → [tex]\displaystyle m∠S[/tex]Edge t [RS] → [tex]\displaystyle m∠T[/tex]Edge r [ST] → [tex]\displaystyle m∠R[/tex]Now that we have the information, we can proceed with the process:
[tex]\displaystyle \frac{t}{sin∠T} = \frac{s}{sin∠S} = \frac{r}{sin∠R} \\ \\ \frac{28}{sin\:58°} = \frac{s}{sin\:111°} → \frac{28sin\:111°}{sin\:58°} → 30,82402055... = s \\ 30,8 ≈ s[/tex]
_______________________________________________
Now that RT has been defined, we can now proceed to solving the third edge, using the Law of Cosines:
[tex]\displaystyle s^2 + r^2 - 2sr\: cos∠T = t^2 \\ t^2 + r^2 - 2tr\: cos∠S = s^2 \\ t^2 + s^2 - 2ts\: cos∠R = r^2 \\ \\ 28^2 + 30,8^2 - 2[28][30]\: cos\:31° = r^2 → 784 + 948,64 - 1680\: cos\:31° = r^2 → \sqrt{254,1978397...} = \sqrt{r^2} → 15,94358303... = r \\ 15,9 ≈ r[/tex]
Your triangle is now complete!
I am joyous to assist you at any time.
Answer:
Step-by-step explanation:
In this case, you would use law of sines due due you being given two angles and one side.
LAW OF ANGLES IN TRIANGLES: 180 - a - b = c
So in this case: 180 - 31 - 58 = m<S = 91
LAW OF SINE: sin A / a = sin B / b = sin C / c
So in this case: sin 31 / ST = sin 58 / 28
28 sin 31 / sin 58 = ST = 17.0
sin 58 / 28 = sin 91 / x
28 sin 91 / sin 58 = RT = 33.0
On a hospital floor, 16 patients have a disease with a mortality rate of 0.1. Find the probability that two of them die. Round to three decimal places
Answer:
The probability that two of them
die is 0.257
Step-by-step explanation:
From the question, we have that the mortality rate is 0.1
So the probability that they will survive is 1-0.1 = 0.9
Now, we want to check that two will die
We are going you use the Bernoulli approximation of the Binomial theorem as follows
= nCr * p^n * q^(n-r)
where n = 16
r = 2
P = 0.1
q = 0.9
Substituting these values;
14 C 2 * 0.1^2 * 0.9^12
= 0.257

The histogram shows the ages of people in a community chorus. How many people in the chorus are 50 or older? Enter your answer in the box.
Answer:
13
Step-by-step explanation:
The computation of the number of people in the chorus are 50 or older is as follows
According to the attached figure
In the age of 50 - 60 , there is 8 people
In the age of 60 - 70 , there is 4 people
In the age of 70 -80, there is 1 people
So, if we do the total that comes
= 8 people + 4 people + 1 people
= 13 people
Hence, the no of people would be 13

Answer:
x = 58°
Step-by-step explanation:
ABCD is a cyclic quadrilateral and opposite angles are supplementary , so
∠ DAB = 180° - 121° = 59°
The angle between a tangent and a chord is equal to the angle in the alternate segment, then
∠ ABD = 63° , thus
x = 180° - (59 + 63)° = 180° - 122° = 58°

in the diagram,the measure of angle ACB is 25 degrees. what is the measure of angle AOB?
Answer:
m<AOB = 50°
Step-by-step explanation:
<ACB = 25° is an inscribed angle of the circle.
<AOB is a central angle of the circle.
Thus, based on the inscribed angle theorem which states that an inscribed angle is ½ the measure of the central angle, therefore:
m<ACB = ½(m<AOB)
Substitute
25° = ½(m<AOB)
Multiply both sides by 2
2*25 = m<AOB
m<AOB = 50°
