Which terms are like terms?
4c, 2, 6f, -5, and 7c
Answer:
2 and -5
4c and 7c
Step-by-step explanation:
2 and -5 have no coefficient
4 and 7 have the same coefficient which in this case is c.
therefore the two pairs are like terms.

Step-by-step explanation:
volume cylinder 1 =
3.14× 3²× 5 = 3.14×45 = 141.3 in³
volume cylinder 2 =
3.14× 5²× 2 = 3.14× 50= 157 in³
the volume difference between cylinder 1 & 2 =
157 - 141.3 = 15.7 in³
2 x – 5y = –47
6 x – 5y = –71
Answer: x = - 6
y = 7
Step-by-step explanation:
Let 2x -5y = -47 be eq. 1
And 6x -5y = -71 be eq. 2
By substrate of 1 - 2:
2x-5y-6x+5y = -47+71
so -4x=24 and x= -6
Substitute x in any eq.
2(-6) - 5y = -47
-5y = -47 +12
-5y = -35 so y= 7

Need help with inscribed angles If M
Given:
In the given circle O, BC is diameter, OA is radius, DC is a chord parallel to chord BA and [tex]m\angle BCD=30^\circ[/tex].
To find:
The [tex]m\angle AOB[/tex].
Solution:
If a transversal line intersect two parallel lines, then the alternate interior angles are congruent.
We have, DC is parallel to BA and BC is the transversal line.
[tex]\angle OBA\cong \angle BCD[/tex] [Alternate interior angles]
[tex]m\angle OBA=m\angle BCD[/tex]
[tex]m\angle OBA=30^\circ[/tex]
In triangle AOB, OA and OB are radii of the circle O. It means OA=OB and triangle AOB is an isosceles triangle.
We know that base angles of an isosceles triangle are congruent.
[tex]\angle OAB\cong \angle OBA[/tex] [Base angles of an isosceles triangle]
[tex]m\angle OAB=m\angle OBA[/tex]
[tex]m\angle OAB=30^\circ[/tex]
In triangle AOB,
[tex]m\angle OAB+m\angle OBA+m\angle AOB=180^\circ[/tex]
[tex]30^\circ+30^\circ+m\angle AOB=180^\circ[/tex]
[tex]60^\circ+m\angle AOB=180^\circ[/tex]
[tex]m\angle AOB=180^\circ-60^\circ[/tex]
[tex]m\angle AOB=120^\circ[/tex]
Therefore, the measure of angle AOB is 120 degrees.
Garnet has a container with 15 1/2 cups of flour in it. She can make one dozen muffins with 2 1/2 cups of flour. How many dozens
of muffins can Garnet make with the flour she had?
Answer:6 1/5
Step-by-step explanation:
Lets start by saying that one dozen is 12 and not a bakers dozen (13)
We will first see how many times 2 1/2 can go into 15 1/2 by dividing the two
[tex]15\frac{1}{2} /2\frac{1}{2}=6\frac{1}{5}[/tex]
then we can verify by multiplying 2 1/2 and 6 1/5
[tex]2\frac{1}{2} *6\frac{1}{5} =15\frac{1}{2}[/tex]
A ball moves in a straight line has an acceleration of a(t) = 2t + 5. Find the position function of the ball if its initial velocity is -3 cm per second and it’s initial position is 12 cm.
Answer:
[tex]s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12[/tex]
Step-by-step explanation:
Relation between acceleration, velocity and position:
The velocity function is the integral of the acceleration function.
The position function is the integral of the velocity function.
Acceleration:
As given by the problem, the acceleration function is [tex]a(t) = 2t + 5[/tex]
Velocity:
[tex]v(t) = \int a(t) dt = \int (2t+5) dt = \frac{2t^2}{2} + 5t + K = t^2 + 5t + K[/tex]
In which K is the constant of integration, which is the initial velocity. So K = -3 and:
[tex]v(t) = t^2 + 5t - 3[/tex]
Position:
[tex]s(t) = \int v(t) dt = \int (t^2 + 5t - 3) = \frac{t^3}{3} + \frac{5t^2}{2} - 3t + K[/tex]
In which K, the constant of integration, is the initial position. Since it is 12:
[tex]s(t) = frac{t^3}{3} + \frac{5t^2}{2} - 3t + 12[/tex]
What is A line that a graph approaches as x or y increases, but never crosses?
Answer:
Asymptotes. The y -axis is a vertical asymptote of the graph. This means that the curve gets closer and closer to the y -axis but does not cross it. Let us consider what happens as the value of x approaches zero from the right for the equation whose graph appears above.

a. Calculate the sample proportion of respondents who have a college degree. The sample proportion of respondents who have a college degree is
Answer:
20% , based on example.
Step-by-step explanation:
Let the number of sampling respondents be = 100
If out of them 35 have low school education, 45 have high school education, 20 have college degree education.
So, sample proportion of respondents, who have college degree = No. of people who have college degree / Total sample respondents = 20 / 100 = 20% or 0.2 proportion.

It is desired to estimate the average total compensation of CEOs in the service industry. Data were randomly collected from 18 CEOs and 95% confidence interval was calculated to be ($2,190,000, $4,720,000). Based on the interval above, do you believe the actual average total compensation of CEOs in the service industry could be $5,000,000
Answer:
Option C
Step-by-step explanation:
Remaining part of the question
a. Yes, and I am sure of that.
b. Yes, and I am 95% confident of that.
c. No, and I am sure of that.
d. No, and I am 95% confident of that.
Solution
The compensation in the range of 95 % is ($2,190,000, $4,720,000). This indicate that there are 95% chances that a given CEO compensation will fall with in the give range.
The given salary range is $5,000,000 which does not lie in the given range. Hence, it is in the region of the graph or bell curve where there are 5% chances that the given salary range will not fall into the given salary range i,e ($2,190,000, $4,720,000)
Hence, the actual average total compensation of CEOs in the service industry can or cannot be $5,000,000
Hence, option C is correct

A telephone pole casts a shadow that is 12 feet long. At the same time, a man standing nearby who is 6 feet tall casts a shadow that is 2 feet 4 inches long. How tall is the
telephone pole to the nearest foot?
The telephone pole is feet tall
Answer:
31 feets
Step-by-step explanation:
Given that :
Telephone shadow Ts = 12 feets
Man's height, Mh= 6 feets
Man's shadow, Ms = 2 feets 4 inches
Height of telephone, Th =?
Recall :
1 foot = 12 inches
x foot = 4 inches
12x = 4
x = 4/12 = 1/3 inches
Hence, man's shadow = 2 1/3 feets =
Using cross multiplication :
Mh / Ms = Th / Ts
6 / 7/3 = Th / 12
6 / 2.33333 = Th / 12
12 * 6 = 2.33333 * Th
72 = 2.33333 Th
Th = 72 / 2.333333
Th = 30.85
Height of telephone pole = 31 feets
