Answer:
Ans: 50 degrees.
Step-by-step explanation:
We know, a straight angle is 180 degrees. Also, the sum of the three angles of any triangle is equal to 180 degrees.
So,
(180-85) = 95,
(180-145) = 35,
A = (180-95-35) = 50.
I'm not sure if its A.
Answer:
C T= S, U = R
Step-by-step explanation:
Congruent angles means they have the same measurement
R = U
S= T

Step-by-step explanation:
A country has two political parties, the Reds and the Blues. The 100-member senate has 4444 Reds and 5656 Blues. Each party must elect a chair and a vice chair from their party's members, and one person cannot be elected for both. How many different outcomes are there for the chair and vice chair elections of both parties
Answer:
There are 5,827,360 different outcomes.
Step-by-step explanation:
Fundamental counting principle:
States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.
In each party:
The order in which the people are selected is important(first is chair, second vice chair), which means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
Reds:
Two from a set of 44. So
[tex]P_{(44,2)} = \frac{44!}{(44-2)!} = 44*43 = 1892[/tex]
Blues:
Two from a set of 56. So
[tex]P_{(56,2)} = \frac{56!}{(56-2)!} = 56*55 = 3080[/tex]
How many different outcomes are there for the chair and vice chair elections of both parties?
Considering both, by the fundamental counting principle:
1892*3080 = 5827360
There are 5,827,360 different outcomes.
A doctor is interested in analyzing the increase in systolic blood pressure caused by a certain chemo drug. Would the doctor be more interested in studying the mean, median, or mode of the systolic blood pressures
Answer:
Mean.
Step-by-step explanation:
When a doctor analyzes the increase in systolic blood pressure caused by a certain chemo drug. The doctor would be more interested in studying the mean of the number of observed systolic blood pressures. As mean would give a better understanding of pressure since it involves the use of all observations. However, it is important to keep in mind that all the units should be considered for the average.
2. If your gross biweekly salary is $3,290, then how much is your annual salary?
I
Answer:
Annual Salary = $85,540
Step-by-step explanation:
There are 52 weeks in a year.
If bi weekly salary is $3290
Then you get paid 26 times.
Therefore annual salary = 26 × 3290 =$85,540
Answer:
$78,960 is your annual salary
Step-by-step explanation:
By saying biweekly, if you mean that your gross salary for every two weeks is $3,290, then your annual salary will be roughly about $78,960
There are about 4 weeks in a month and you're getting your gross salary biweekly. So $3,290 times 2 equals $6,580. This is your monthly gross salary.
Now, multiply $6,580 times 12 to find out your annual salary because there are 12 months in a year. $6,580 times 12 equals $78,960. This is your annual salary

50% of a number is x. What is 100% of the number? Assume x > 0.
Answer:
2x > 0
Step-by-step explanation:
[tex]\frac{50}{100} :\frac{x}{y}[/tex]
50 × y = x × 100
50y = 100x
50y ÷ 50 = 100x ÷ 50
y = 2x
Solve 5(2x – 3) = 5x – 10 for x.
Answer:
x=1
Step-by-step explanation:
5(2x – 3) = 5x – 10
Distribute
10x -15 = 5x-10
Subtract 5x from each side
10x-15-5x = 5x-5x-10
5x -15 = -10
Add 15 to each side
5x-15+15 =-10+15
5x = 5
Divide by 5
5x/5 = 5/5
x=1
Answer and Step-by-step explanation:
To solve for x, first distribute the 5 to the 2x and 3.
10x - 15 = 5x - 10
Now, add 15 to both sides and subtract 5x to both sides of the equation.
5x = 5
Divide both sides of the equation by 5.
x = 1
The answer is x = 1

Teresa deposits $800 into an account that pays simple interest at a rate of 2% per year. How much interest will she be paid in the first 2 years?
Answer:
I'll setup the problem and you can do the computation
Step-by-step explanation:
The formula for simple interest:
I = P*r*t
I = interest
P = deposit
r = interest rate per period
t = number of periods
P = $800
r = 0.02
t = 2

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a radius of 12 feet and a height of 17 feet. Container B has a radius of 10 feet and a height of 18 feet. Container A is full of water and the water is pumped into Container B until Containter B is completely full.
To the nearest tenth, what is the percent of Container A that is empty after the pumping is complete?
Answer:
Step-by-step explanation:
Container A = 75.36 x 17 = 1,281.12
Container B = 62.8 x 18 = 1,130.4
1,281.12 - 1,130.4 = 150.72 is left in container A.
So, 1,130.4 was taken out of it.
1,281.12 divided by 1,130.4 = 1.13
move the decimal over two to the right. Or times it by 100.

A pyramid with a volume of 36 cm^3 has a base with a length of 4 cm and a width of 3cm. What is the volume of h?
Answer:
9 = h
Step-by-step explanation:
The formula of finding the volume of a pyramid is:
V = l * w(h / 3)
We know that Volume is 36, base or Length is 4 and the Width is 3, therefore;
36 = 4 * 3 (h/3)
36 = 12 * h/3
36/12 = h/3
3 = h/3
3(3) = h
9 = h
Therefore the height or h of the pyramid is 9cm

Find the zeros of y = 4x2 – 12x – 16
Answer:
x=-1 or x=4
Step-by-step explanation:
First divide by 4 to get rid of the factor 4 at x², then you have:
x² - 3x - 4 = 0
to factor that, look for two numbers that when added, give -3, and when multiplied, give -4. This is guesswork but usually doable:
-4 + 1 = -3
-4 * 1 = -4
so -4 and +1 are our numbers.
The factorization is therefore: (x - 4)(x + 1) = 0, and the solutions are
x-4 = 0 or x+1 = 0, so x=4 or x=-1

MT is a diameter of OE. Calculate the measure of AT.
A. 24°
B. 48°
C. 96°
D. 180°
Need the answer, click the picture to see the thingy
Answer:
C. 96°
Step-by-step explanation:
m<AME = 48° is an inscribed angle
Arc AT = intercepts arc
Based on the inscribed angles theorem, we have:
m<AME = ½(arc AT)
48° = ½(arc AT)
Multiply both sides by 2
48° × 2 = ½(arc AT) × 2
96° = arc AT
Arc AT = 96°

assume that a consumer has a given budget or income of $12 and that she can buy only two goods, apples or bananas. The price of an apple is $1.50 and the price of a banana is $0.75. What is the slope of the budget line if the quantity of apples were measured on the horizontal axis and the bananas on the vertical axis?
Answer:
-2
Step-by-step explanation:
The equation of a straight line is given by:
y = mx + b
where y is the variable on the vertical axis, x is the variable on the horizontal axis, m is the slope of the line = change in vertical axis / change in horizontal axis, b is the y intercept.
Given that the quantity of apples were measured on the horizontal axis and the bananas on the vertical axis. Therefore let y represent the quantity of bananas and x represent the quantity of apples. The price of banana is $0.75 while that of apple is $1.50, Hence:
0.75y + 1.5x = 12
0.75y = -1.5x + 12
y = -2x + 16
Hence comparing with y = mx + b, the slope of the budget line is -2

Determine if the type of sequence of the following terms.
2, 5, 10, 17, 26, 37,
...
O Arithmetic
O Polynomial
O Neither
O Geometric
Question
Answer:
B: polynomial
Step-by-step explanation:
The sequence given is;
2, 5, 10, 17, 26, 37,...
From this sequence, the first difference between consecutive terms is respectively;
3, 5, 7, 9, 11...
We can see that the differences gotten are not constant.
Now, let's find the second difference between the consecutive first differences respectively;
2, 2, 2, 2...
This second difference is constant and thus we can say that the terms form a quadratic sequence of the form;
f(x) = an² + bx + c
Where the quadratic coefficient is two times the second difference.
Thus;
2a = 2
a = 1
And where c is the 0th term.
Thus, this is a quadratic sequence. Since quadratic functions are 2nd degree polynomials, then this is said to be a polynomial sequence.
