Matt has $900 in a checking account, has $15,000 in investments, owns an
$8000 car, and owns a $30,000 house. What is the total value of his large
assets?
A. 53,900
B.23,000
C. 15,900
D. 38,000
The total value of his large assets is $53,900.
What are Assets?Assets are defined as the possessions that a person or the company holds which has a value which affects positively for the person or the company.
Given that,
Amount in a checking account = $900
Amount as investments = $15,000
Amount for the car = $8000
Amount for the house = $30,000
Total value for the assets = $900 + $15,000 + $8000 + $30,000
= $53,900
Hence the total value of the asset is $53,900.

A train travels at 45 miles per hour. Write and equation that represents the distance, d, that the train will travel, in t hours.
Answer:
d = 45 * t
Step-by-step explanation:
We know the equation as dert
distance equals rate * time
d = 45 * t
Answer:
d = 45 * t
Step-by-step explanation:
Step 1: Ok so for a. we can just need to build a equation representing the space the practice travels in t hours:
We can also recognize that it travels 45 mph, in order that is representing by 45(t).
d is the distance. So the equation is d = 45(t)
Step 2: For phase b. we change 2.5 with t a the equation. Then we solve it
d = 45(2.5)
45 * 2.5 = 112.5

50 min
Answer:
50 minutes.
Step-by-step explanation:
7*50 = 350
The division is one of the four fundamental arithmetic operations. The time needed by John to burn 350 calories is 50 minutes.
What is Division?Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
As it is given that to burn 7 calories by bicycling at 10mph John needs 1 minute. Therefore, the time needed to burn 350 calories by bicycling at 10mph is,
[tex]\rm Time\ Needed = \dfrac{\text{Number of calories}}{\text{Rate at which calories is burned}}\\\\\\Time\ Needed = \dfrac{350}{7}= 50\ minutes[/tex]

A fast food chain surveyed a random sample of students to determine what pizza they prefer. Cheese pizza was preferred by 40 students. Pepperoni pizza was preferred by 28 students. Based on the results, how many of the 340 students can be expected to prefer cheese pizza?
Answer:
11.76
Step-by-step explanation:
We are given that,
Total number of students = 340
Students that prefer cheese pizza = 40
Students that prefer pepperoni pizza = 28
Thus, we get that,
The proportion of students that prefers cheese pizza =
i.e. The proportion of the students preferring cheese pizza = 0.1176 = 11.76%
Hence, 11.76% of the students prefer cheese pizza.
The amounts of Cathy’s last six clothing purchases were $109, $72, $99, $15, $99, and $89. For each question, choose the mean, median, or mode and give its value.
C.) Which value would Cathy NOT tell her parents to convince them that she needs an increase in her allowance?
{I only need help on part C}
Answer:
The mean value = $80.5
Step-by-step explanation:
The value of her last six spendings are $109, $72, $99, $15, $99, and $89.
For the mean.
Mean = Total spendings/number
Mean =483/6
Mean = $80.5
For the median.
Lets arrange it in ascending order
$15 ,$72, $89, $99, $99, $109
The middle values are two.
Median = (89+99)/2
Median = 188/2
Median = $94
For the mode
$15 ,$72, $89, $99, $99, $109
Highest occuring is $99 with two frequencies.
To convince her parents that she needs an increase in allowance she would show them the bigger spendings .
So the least value on the list it's mean value which is $80.5.
What are the slope and the y-intercept of the linear function that is represented by the graph?
On a coordinate plane, a line goes through points (negative 3, 0) and (negative 2, 4).
The slope is 3, and the y-intercept is 9.
The slope is 3, and the y-intercept is 12.
The slope is 4, and the y-intercept is 9.
The slope is 4, and the y-intercept is 12.
Answer:
The slope is 4, and the y-intercept is 12.
Step-by-step explanation:
In the given question, the line goes through points (-3,0) and (-2,4).
We need to find the slope and the y-intercept of the line.
Finding Slope:Slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
With points (-3,0) and (-2,4):
[tex]m=\frac{4-0}{-2-(-3)}=\frac{4}{1}=4[/tex]
The slope of the line is 4.
Finding y-intercept:An appropriate equation for what we have so far is:
[tex]y=4x+b[/tex]
We can solve for 'b' to get the y-intercept.
Replace 'x' and 'y' with one of the coordinates and solve for 'b':
[tex]4=4(-2)+b\\4*-2=-8 \leftarrow \text {Distribute}\\4=-8+b\\4+8=-8+8+b \leftarrow \text {Addition Property of Equality} \\\boxed {12=b}[/tex]
The y-intercept is 12.
Final Answer:The answer should be: "The slope is 4, and the y-intercept is 12."
Answer:
The answer is d, which is the slope of 4 and the y- intercept is 12.

Solve the following SYS
y = 6x + 5
y= 4x - 11
This is the second question
Answer:
x=-8, y= -43
Step-by-step explanation:
y = 6x + 5
y= 4x - 11
Since both equations are equal to y, we can set them equal to each other
6x + 5= 4x - 11
Subtract 4x from each side
6x-4x+5 = 4x-4x-11
2x+5 = -11
Subtract 5 from each side
2x+5-5 = -11-5
2x = -16
Divide each side by 2
2x/2 = -16/2
x = -8
Now we need to find y
y = 6x+5
y = 6(-8) +5
-48+5
-43
Answer:
x = -8 y = -43
Step-by-step explanation:
y = 6x + 5
y= 4x - 11
6x + 5 = 4x - 11
2x = -16
x = -8
y = 4(-8) - 11
y = -32 - 11
y = -43
Find the area of the circle. Round your answer the nearest whole number, if necessary.
Answer:
The area of the circle is 314 in^2.
Step-by-step explanation:
10 inches is the radius.
The formula for the area of a circle is pi times radius squared.
So your equation would be: [tex]A=\pi (10)^2[/tex]
10^2 = 100
Then you do [tex]\pi[/tex] or 3.14 times 10 = 314.1592654 or just 314.

The Area of Circle whose radius is 10 inch is 314 inch².
What is Area of circle?The area of a circle is the region of two-dimensional space occupied by a circle.
The area of a circle is pi times the radius squared (A = π r²).
i.e., Area of Circle = πr²
We have radius of Circle as
r = 10 inch
Using the Formula
Area of Circle = πr²
= 3.14 x (10)²
= 3.14 x 100
= 314 inch².
Thus, the Area of Circle is 314 inch².

Show the Euler-Descartes formula holds for the Great Pyramid of Cheops
Answer:
For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula
Step-by-step explanation:
The great pyramid of Cheops is a square based pyramid therefore we have;
V + F = E + 2
Where:
V = Vertices
F = Faces
E = Edges
Hence, we have for a square pyramid;
V = 5 vertices (One at the peak, and four at the base edges)
F = 5 faces (The four lateral or side faces and the base)
E = 8 edges ( The four lateral edges and the four base edges)
Hence;
5 + 5 = 8 + 2 which proves Euler-Descartes formula.

2. Solve by substitution: y = -x + 2 AND 2x - y = -5*
Answer:
Step-by-step explanation:
y = -x + 2 -------(i)
2x - y = -5 -----------(ii)
Substitute y = -x + 2 in equation (ii)
2x - (-x + 2) = -5
2x + x - 2 = - 5
3x - 2 = -5 {add 2 to both side}
3x -2 + 2 = -5 + 2
3x = -3 { divide both sides by 3}
3x/3 = -3/3
x = -1
Plug in the value of x in equation (i)
y = - (-1) + 2
y = 1 +2
y = 3
