At the end of a year, the gross debt of a country stood at about $25 trillion. Express this amount in dollars per person, assuming that the population of the country is about 314 million
Answer:
$79,617.83 per person
Step-by-step explanation:
$25,000,000,000,000 / 314,000,000 = $79,617.83 per person
The amount of debt per person is $79,617.83.
The total debt is $25 trillion and the number of people in the country is 314 million.
The debt per person is:
= Total debt / population
= 25,000,000,000,000 / 314,000,000
= $79,617.83
The amount of debt per person is therefore $79,617.83.

Answer:
8.94
Step-by-step explanation:
with a right triangle, you can use the Pythagorean Theorem, a^2 + b^2 = c^2
if you put in the values that you have, which are 8 and 4 into the equation, you get 8^2 + 4^2 = c^2
Now simplify, and you get 16 + 64 = c^2 which can then be further simplified to 80 = c^2
To get the value c all by itself, you have to square both sides. Square root of 80 becomes 8.94, and square root of c^2 becomes just a 'c'.
Therefore, you get 8.94 = c, meaning that the missing length (hypotenuse) is 8.94 units long.

2. 3x - 5y = -2
x + 3y = 4
Let us multiply equation 2 by three, so we can use the elimination method.
3x + 9y = 12
Now, let us subtract equation 1 from equation 2.
3x + 9y - 3x + 5y = 12 + 2
14y = 14
y = 1
Let us substitute this value of y in equation 2.
x + 3(1) = 4
x = 4 - 3
x = 1
3. -3x + 3y = -6
6x + 4y = 42
Let us multiply equation 1 by 2, so we can use the elimination method.
-6x + 6y = -12
Let us now add equations 1 and 2, so as to eliminate x.
6x + 4y -6x + 6y = 42 - 12
10y = 30
y = 3
Let us now substitute this value of y in equation 1, so as to find x.
-3x + 3(3) = -6
-3x + 9 = -6
-3x = -15
3x = 15
x = 5
4. 12x + 4y = 20
2x - 2y = -2
Let us multiply equation 2 by 2, so as to use the elimination method.
4x - 4y = -4
Let us now add equations 1 and 2, so as to eliminate y.
4x - 4y + 12x + 4y = -2 + 20
16x = 18
x = [tex]\frac{18}{16}[/tex] = [tex]\frac{9}{8}[/tex] = 1.125
Let us substitute this value of x in equation 2, so as to find y.
2(9/8) -2y = -2
9/4 - 2y = -2
-2y = -2 - 9/4
2y = 17/4
y = [tex]\frac{17}{8}[/tex] = 2.125
Is this triangle acute, right, or obtuse?
Answer:
acute
Step-by-step explanation:
every angle is under 90 degrees
Answer:
The triangle is acute.
Step-by-step explanation:
-According the to following triangle, the angles are acute, because acute angles less wider and they measure less than 90°.
-The reason why the triangle is not a right or obtuse, is because right angles are angles that measure exactly 90°, and obtuse angles are angles that are much wider and they measure greater than 90°.
A formula for finding SA, the surface area of a rectangular prism, is
SA = 2(ab + ac + bc), where a, b, and c represent the lengths of the edges of the prism. What is the surface area of this prism if a = 12 inches, b = 6 inches, and c = 4 inches?
A. 240 in. 2
B. 248 in. 2
C. 288 in. 2
D. 258 in.2
Answer:
Option C.
Step-by-step explanation:
It is given that the surface area of a rectangular prism, is
[tex]SA=2(ab+ac+bc)[/tex]
where a, b, and c represent the lengths of the edges of the prism.
We need to find the surface area of this prism if a = 12 inches, b = 6 inches, and c = 4 inches.
Substitute a=12, b=6 and c=4 in the above formula.
[tex]SA=2((12)(6)+(12)(4)+(6)(4))[/tex]
[tex]SA=2(72+48+24)[/tex]
[tex]SA=2(144)[/tex]

a triangle's sum of interior angels is equal to 180°.
so we have this equailty
y+10°+50+2y = 180
3y+60° = 180.
to solve better, im throwing 60 near 180. 60° is going to be -60 cause of it.
3y=180-60 = 3y=120
now im dividing both 3. because both can divide by 3.
3y/3 = 120/3 = y=40

Assume that you want to replace your sailboat with a larger one in 3 years. To save for a
down payment for this purchase, you deposit $2,000 for 3 years in a bank account that pays
10% annual interest, compounded annually. How much will be in the account at the end of 4
years?
Answer: $11,600
Step-by-step explanation:
$2000 * 10% = $200
y = 200x + $2,000
12 * 4 = 48
48 = x
y = 200(48) + $2,000
y = $9,600 + $2,000
y = $11,600

The table below shows the survey results for six randomly selected lions from five different zoos.
Gender No. of Offspring Age, years
This data set contains
three variables, two of which are categorical
Othree variables, all of which are categorical
Othree variables, none of which are categorical
three variables, one of which is categorical
Answer:
Correct option: fourth one
Step-by-step explanation:
We can see in the table that we have three variables: the gender of the lion, the number of offspring and the age in years.
From these three variables, the gender is a categorical variable, because it can only assume a finite number of values (in this case, 2 values: M or F)
The other two variables (no. of offspring and age) can theoretically assume an infinite number of values (any non-negative integer number).
So the correct option is the fourth one: three variables, and one of them is categorical.

3. The area of the base of a can is 45 square inches. Its height is 12 inches. If 1/3 of the
height is cut off, what will be the volume of the can?*
a) 540 cubic inches
b)180 cubic inches
c) 280 cubic inches
d) 360 cubic inches
Answer:
The correct answers is D
D) 360 cubic inches
Step-by-step explanation:
We know that the Area of the base of the can is given by
A = 45 inch²
Initial height of the can = 12 inches
Fraction of height cut off = 1/3
Calculate the final height after cutting off:
Find 1/3 of 12 inches:
[tex]\frac{1}{3}\cdot12=4[/tex]
Subtract the answer from 12 to get final height:
Final height = 12- 4 = 8 inches
Can is a form of cylinder, so:
Volume = (Area)(height)
[tex]V=45\cdot8\\V=360inch^3[/tex]

John takes 2 hours to cut the grass in the lawn of a circular field. To cut the grass in a similar adjacent circular lawn of twice the radius, how many hours can John expect to take?
Answer:
8
Step-by-step explanation:
The area of a circle with twice the radius is 4 times the area of the smaller circle. If John's hours are proportional to area, we expect it will take him 4 times as long for the larger area.
John can expect to take 8 hours cutting the grass in the larger lawn.
___
The area of a circle with radius r is ...
A = πr²
The area of a circle with radius 2r is ...
π(2r)² = 4πr² = 4A . . . . . 4 times the area of the smaller circle

The product of [tex]5 \times 0.2 = 1[/tex] which is not a irrational number but a whole number.
Option B is not the correct answer.
C. [tex]\sqrt{5}[/tex]
The product of
[tex]\sqrt{5} \times 0.2 \\\\= \frac{2}{10}\times \sqrt{5} \\\\= \frac{1}{5} \times \sqrt{5}\\\\=\frac{1}{\sqrt{5} }[/tex]
which is a irrational number .
Option C is the correct answer.
D. [tex]\frac{3}{4}[/tex]
The product of
[tex]\frac{3}{4} \times 0.2\\\\= \frac{3}{4} \times\frac{2}{10}\\ \\=\frac{3}{20}[/tex]
