10. Congress may override a presidential veto with a ?
A. Majority vote. C. Two-thirds vote B. Three-quarter vote. D. unanimous vote
C. Two-thirds vote
Step-by-step explanation:To help with checks and balances, the consitution allows congress to override a presidential veto with a two-thirds vote; also known as a constitutional majority.
Intial Vote
When Congress first votes on a normal bill (not a consitutional change) all that is required is a simple majority. A simple majority means more than 50 percent.
Presidential Veto
Just because something is passed by Congress does not mean that it will be a law. The President still has to sign the bill into law. However, the President has the option to veto the bill.
Overriding a Veto
If a bill is overridden, Congress can move to override the veto. If they want to override the veto, there must be a 2/3's majority that agrees to pass the bill again.
Additionally, when overriding a veto any votes that are not affirmative, this includes abstentions and absent voters, are considered opposing votes. For example, if 2 congressmen did not show up to vote, then their votes would automatically be counted against the bill.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that John must mount a box which is 12⁵/₈ inches wide. He wants to leave 7¹/₂ inches on each side of the box.
The amount of space needed by John will be calculated as below:-
E = 12⁵/₈ + 2(7¹/₂)
E = 12⁵/₈ + 15
E = 27⁵/₈ Inches
Hence, the amount of space needed by John will be 27⁵/₈ inches.

A cone with a radius of 6 meters has a volume of 542.87m³. Find the slant height.
The slant height of the cone is = 15.6m. To calculate the slant height is further described below.
What is the slant height of a cone?The radius of the cone is = 6m
The volume of the cone = 542.87m³
The height of the cone can be determined using the formula below;
V=πr²h/3
542.87 = 22/7×6²×h/3
542.87= 3.14×36×h/3
542.87= 113.04× h/3
Make h the subject of formula,
h = 542.87×3/113.04
h = 1628.61/113.04
h= 14.4m
Therefore the slant height ,
l=√r²+h²
l = √6²+14.4²
l= √36+207.36
l=√243.36
l= 15.6m
Therefore, the slant height of the cone is = 15.6m.

Since ∠A and ∠B forms a straight line, ∠A and ∠B are a linear pair.
Linear pair:
A linear pair is the sum of two angles that forms a straight line (180°).
⇒ ∠A + ∠B = 180°
Measure of ∠A:
Subtract the measure of ∠B from 180 to determine the measure of ∠A.
⇒ ∠A = 180 - ∠B
Measure of ∠B:
Subtract the measure of ∠A from 180 to determine the measure of ∠B.
⇒ ∠B = 180 - ∠A
*Let us take a few examples to understand the concept better.
Example (Given measure of ∠B):Let the measure of ∠B (In the triangle shown) be 105°.
What is the measure of ∠A?
Solution:
Substitute the measure of ∠B in the equation ∠A = 180 - ∠B:
⇒ ∠A = 180 - ∠B⇒ ∠A = 180 - 105Simplify the equation:
⇒ ∠A = 180 - 105⇒ ∠A = 75°Therefore, the measure of ∠A is 75°.
Example (Given measure of ∠A):Let the measure of ∠A (In the triangle shown) be 60°.
What is the measure of ∠B?
Solution:
Substitute the measure of ∠A in the equation ∠B = 180 - ∠A:
⇒ ∠B = 180 - ∠A⇒ ∠B = 180 - 60Simplify the equation:
⇒ ∠B = 180 - 60⇒ ∠B = 120°Therefore, the measure of ∠B is 120°.

Step-by-step explanation:
Teachers average out your grades. In order to average numbers, you add all the numbers and divide by the number of numbers you just averaged. If you add 200 to 54 you get 254. 254 divided by 3 is 84.

Determine the equation of the circle with center (8,5) containing the point (-4,21)
Answer:
(x-8)² + (y-5)² = 400
Step-by-step explanation:
general equation of a circle : (x-h)² + (y-k)² = r²
where (h,k) is at center and r = radius
here we are given the center as well as a point on the circle
first we will need to identify the radius by finding the distance between the center and the point on the circle using using the distance formula ( we know this is the radius because the radius is a line that goes on the center of the circle to any point on the circle )
Identifying the radius using the distance formula
Distance formula : [tex]d=\sqrt{(x_2-x1)^2+(y_2-y_1)^2}[/tex]
where the x and y values are derived from the two given points
Given points are (8,5) and (-4,21)
Assigning variables we get (x1,y1) = (8,5) , so x1 = 8 and y1 = 5
and (x2,y2) = (-4,21) so x2 = -4 and y2 = 21
Plugging this into the formula we get
[tex]d=\sqrt{(-4-8)^2+(21-5)^2}[/tex]
==> subtract values inside of parenthesis
[tex]d=\sqrt{(-12)^2+(16)^2}[/tex]
==> evaluate exponents
[tex]d = \sqrt{144+256}[/tex]
==> add 144 and 256
[tex]d=\sqrt{400}[/tex]
==> take the square root of 400
[tex]d=20[/tex]
so the radius is 400
Finding the equation of the circle
again we have the general equation of a circle as (x-h)² + (y-k)² = r²
where (h,k) is at center and r = radius
here the center is at (8,5) and the radius is 20
so (h,k) = (8,5) so h = 8 and k = 5 and radius is 20 so r = 20
plugging these values into the general equation of a circle we get
(x-8)² + (y-5)² = 20²
==> evaluate exponent
(x-8)² + (y-5)² = 400
and we are done!

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Fatoumata sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
7 visitors purchased no costume.
143 visitors purchased exactly one costume.
16 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase no costume as a fraction in simplest form.
The probability that the next person will purchase no costume is 7/166 if the 7 visitors purchased no costume.
What is probability?
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
Total number of visitors = 7+143+16 = 166
Number of visitors purchased no costume = 7
The probability that the next person will purchase no costume:
= 7/166
Thus, the probability that the next person will purchase no costume is 7/166 if the 7 visitors purchased no costume.

Assume a bank loan requires an interest payment of $85 per year and a principal payment of $1,000 at the end of the loan's eight-year life. What would be the present value of the loan if the interest rate is 8 percent?
Considering the situation described above, what would be the present value of this loan is $1,000.
This is explained below:
Given that the loan interest rate is $85 85/1000 = 8.5
Then the market interest rate is => 8.5 percent
Therefore, given that there is no difference between the market rate and the loan rate, then the loan is expected to be sold at $1,000 which is the face value of the loan.
To prove it, we have the following:
PV of the annuity of $85 during 8 years at an 8.5% market rate
C => 85
Time => 8
Rate => 0.085
C × { [1 - ( 1+ r ) ] ^-time } ÷ rate = PV
85 × [1 - (1 + 0.085)^-8] ÷ 0.085 = PV
PV =. $479.3306
Present value of the maturity date:
Maturity 1000
Time => 8
Rate => 0.085
Maturity ÷ (1+rate)^rate = PV
1000 ÷ (1+0.085)^8 = PV
PV => $520.6694
Therefore, the Total present value
=> PV c $479.3306 + PV m $520.6694
=> Total $1,000.
Hence, in this case, it is concluded that the correct answer is $1,000.
