What’s the measure for angle C?
Answer:
152°
Step-by-step explanation:
Angles B and A of the isosceles triangle have the same measures, so we have ...
∠B = ∠A
(x -14)° = (x/2)°
2x -28 = x . . . . . . divide by °, multiply by 2
x = 28 . . . . . . . . . .add 28-x to both sides
Then the base angles, A and B, both have measure (x/2)° = 14°.
The third angle, C, will bring the total to 180°.
∠A + ∠B + ∠C = 180°
∠C = 180° - 2(14°)
∠C = 152°
16 p = 208 p = Pls help quick
Answer:
p=0
Step-by-step explanation:
When you isolate both variables, one side becomes 0.
Answer:
p = 0
Step-by-step explanation:
16p=208p
Subtract 208p from both sides.
16p−208p=0
Combine 16p and −208p to get −192p.
−192p=0
Product of two numbers is equal to 0 if at least one of them is 0. Since −192 is not equal to 0, p must be equal to 0.
p=0

Categorical(qualitative) or quantitative. Indicate whether quantitative data are continuous or discrete.
1. Gender
2. Age
3. Grade Point Average
4. Number of Courses Currently Enrolled
5. Enrollment Status (Part-Time or Full-Time)
Answer:
1. Gender - qualitative
2. Age - Quantitative (Discrete)
3. Grade point Average - quantitative (Continuous )
4. Number of courses currently enrolled - quantitative (discreet)
5. Enrollment Status - qualitative
Step-by-step explanation:
Qualitative variables are those which are non-numeric, usually made up of strings or words. The quantitative variables are numeric, usually composed of digits and numbers.
Discreet variables have a finite or limited number of values which are countable as opposed to continuous variables with a non-finite range and hence, uncountable.
Gender is a qualitative variable as it is composed of non-nemeric labels which could be either Male or Female.
Age - is numeric and hence quantitative, since age is usually expressed in years, hence it is discreet.
Grade point Average is a quantitative and continuous variable due to its numeric nature and the fact that it can take up an infinite number of possible values including decimal values.
Number of courses enrolled is numeric can take a finite number of values, hence, it is discreet.
Enrollment status is qualitative as it is split into :
Part time or full time.

9. Find the slope of a line parallel to 3x - y = 1.
Answer:
slope = 3
Step-by-step explanation:
The slope of a line parallel to the given equation share the same slope. Note the slope intercept formula:
y = mx + b
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
First, isolate the variable, y. Subtract 3x from both sides:
3x (-3x) - y = 1 (-3x)
-y = -3x + 1
Next, divide -1 from both sides:
(-y)/-1 = (-3x + 1)/-1
y = 3x - 1
You are solving for the slope of a line parallel to the given equation. Since you are solving for parallel, the slope would be shared.
3 would be the slope of the line.

All you have to do is move all the points to the right 6 numbers because it says x+6. For example, A is (-5,-1). Move to the right 6 times, so (-5+6,-1) which is (1, -1). So the new point of A is (1, -1). Do the same with the others. Now that we got the new rectangle in the fourth quadrant, you want to move it counterclockwise around the origin, which is 0. Clockwise is like a clock, it goes around the middle going to the right. Counterclowise is the same, except it goes to the left around the middle of the clock. You can sort of apply that to this. Go counterclockwise around the middle, in this case being the origin, 0. Move the rectangle up to the first quadrant because counterclockwise is going around to the left. So, if the rectangle goes around to the left, then that means that it is now vertical...because it turns to the left making it straight if you go counterclockwise. Now the point A is on the bottom left because the rectangle got turned. If you turned it properly, then A should be at (1,1). Apply the same thing to the other points. D is the only one with point A being at the point (1,1), so that is correct. Check the other points anyway.
A swimming pool holds exactly 184 cubic yards of water. Assuming that the depth of the pool is the same everywhere, what is the depth in meters if the pool is exactly 30.0 feet long and 20.0 feet wide
Answer:
The depth of the swimming pool is 2.52 meters
Step-by-step explanation:
To solve this problem properly, the first thing we are to do is to ensure that we are working in the same units at all points in time during the solution.
First of all, we will convert the length and breadth of the pool from feet to yards.
1 foot = 0.3333 yards
30 feet = 10 yards
20 feet = 6.67 yards.
The next step is to find the depth of the swimming pool using the volume and the available dimensions.
From the dimensions given, we can tell that the swimming pool will have a cuboidal shape. This means that the volume will be = length X breadth X depth.
hence we have
184 = 10 X 6.67 X depth
depth = 2.76 yards.
The final step will be to convert the answer we obtained in yards to meters.
1 yard = 0.9144metres
2.76 yards = 2.52 meters
The depth of the swimming pool is 2.52 meters
Jess borrows 250 from the bank. The band chargEs 11% simple interest over 2 years.
How much will Jess owe the bank at the end of 2 years?
Answer:
$305
Step-by-step explanation:
You have to use the following formula to calculate the accrued amount:
A=P(1 + rt), where:
A= accrued amount
P= principal amount= $250
r= rate of interest= 11%
t= time period= 2 years
Now, you have to replace the values in the formula:
A=250*(1+0.11*2)
A=250*(1+0.22)
A=250*1.22
A=305
According to this, at the end of 2 years, Jess owes the bank $305.
If you wish to have $60,000 in 8 years, how much do you need to deposit in the bank today if the account pays 9% using present value and future value.
Answer:
Amount to deposit= $26799.0
Step-by-step explanation:
Amount A = $60,000
Years t = 8 years,
Rate R = 9% .
A= p(1+r/n)^(nt)
60000= p(1+0.09/9)^(9*9)
60000= p(1+0.01)^(81)
60000= p(1.01)^81
60000= p(2.23888)
60000/2.23888= p
26799.1138= p
P= $26799.0
Amount to deposit= $26799.0
To be able to have $60,000 after 8 years at a rate of 9% per annum, the amount to deposit today is $30,111.98
You can solve this using the Future Value formula which is:
Future value = Present value x ( 1 + rate)^ number of years
You have everything except the present value so solve for it:
60,000 = PV x ( 1 + 9%)⁸
60,000 = PV x 1.9925626416901921
PV = 60,000 / 1.9925626416901921
PV = $30,111.98
In conclusion, you should deposit $30,111.98 today.

Write the following sentence using mathematical symbols. Twice the difference of x and 7 is greater than the reciprocal of 10.
Answer:
2(x-7) > 1/10
Step-by-step explanation:
The statement says, twice the difference of x and 7. This implies that it wants the difference of x and 7, x - 7, and it wants twice that difference so:
2 ( x - 7 )
The statement continues that this twice the difference of x and 7 is greater than the reciprocal of 10. The reciprocal of 10 is 0.1 or 1/10.
Hence, the statement should be written as such:
2 ( x - 7 ) > 1/10 OR 2 ( x - 7 ) > 0.1

Eric Shotwell borrows $24,600 from a certain bank. The interest charge amounts to $8,592. What equal monthly payments (in $) must Eric make in order to pay back the loan, with interest, in 36 months?
Answer:
He will pay $922 Eve month where
$238.6667 is the interest in the payment
Step-by-step explanation:
Eric Shotwell borrows $24,600 from a certain bank. The interest charge amounts to $8,592 to be paid back in 36 months monthly.
Total money to be paid back
= 24600+8592
Total money to be paid back
= $33192
Now for each month in 36 months, a certain amount must be paid
That amount= 33192/36
= $922
But if the interest wasn't added
He'll pay= 24600/36
=$683.333
So the interest amount in the payment every month= 922-683.333.
= $238.6667
He will pay $922 Eve month where
$238.6667 is the interest in the payment
The calculation is as follows:Total money to be paid back
= 24600+8592
= $33192
Now for each month in 36 months, a certain amount must be paid
That amount= [tex]33192\div36[/tex]
= $922
Now in the case when the interest wasn't added
He'll pay= [tex]24600\div 36[/tex]
=$683.333
So the interest amount in the payment every month is
= 922-683.333.
= $238.6667

Subtract 4 from both sides of the equation.
2x(+4-4)=(-19-4)
2x=(-19-4)
2x= -23
Divide both sides of the equation by 2.
2x/2= -23/2
x= -23/3
x= -11.5
Next, let's find what 2x-14 is equal to. Substitute -11.5 in for x.
