if a desktop computer costs $800 and a tablet costs $400, how can someone determine how many of each they can buy with $20000?
Answer:
it depends how many of each you want, you would take $800 for the price of the item or $400. then x for the amount of items you need. then put that all over your total and divide.
so it would look like this
Step-by-step explanation:
800(x)

calculate the rise and run to find the slope of the line
Answer:
3
Step-by-step explanation:
To find the slope of the line, you can use the formula rise/run.
Every time the graph moves one unit across the x-axis, it moves three spaces up. Therefore,
Rise = 3
Run = 1
Now to plug this into our formula:
3/1 = 3
The slope of the line is 3.

There were 45 runners to start a race. In the first half of the race 2/3 of them dropped out. In the second half 2/5 of the remaining runners dropped out. How many runners finished the race?
Answer:
18 racers finished.
Step-by-step explanation:
In the first half, 30 racers dropped out, because 2/3 of 45 is 30. In the 2nd half, 12 racers dropped out, because that is 2/5 of 30. So, in the end, 18 racers finished. (I might have done this wrong i did my best)

Raphael purchases a new DVD at M-Mart. He
pays 8% in tax on the cost of the DVD. If the tax
amount is $1.20, how much does Raphael
spend on the DVD, including tax?
Answer:
The amount Raphael spend on DVD including tax is $16.2
Step-by-step explanation:
Tax on DVD = 8%
Amount of tax = $1.20
We need to find the amount Raphael spend on DVD including tax.
Let the cost of DVD = x
We can write the equation: [tex]8\%\:of\:x=1.20[/tex]
Because the tax amount is 8% of actual cost and is equal to 1.20
Now solving to find x:
[tex]8\%\:of\:x=1.20\\8\%\times\:x=1.20\\\frac{8}{100}\times x=1.20 \\x=1.20 \times \frac{100}{8}\\x= 15[/tex]
So, the cost of DVD = $15
Now, The amount Raphael spend on DVD including tax = Cost of DVD + Tax
The amount Raphael spend on DVD including tax = 15 + 1.2
= 16.2
So, The amount Raphael spend on DVD including tax is $16.2

joseph is planting a garden. he plants 2 tomato plants for every 5 peppers. If joseph plants 14 tomato plants how many pepper plants does he plant?
Answer:
Ratio of tomato plant to that of pepper plant = 2:5
Let x be the number of pepper plants for 14 tomato plants.
Now, according to the question,
2:5 = 14:x
14×5 = 2x
x = 70/2 = 35 plants.
Step-by-step explanation:
So he/she would have 35 pepper plants to plant

Which set of numbers could represent the lengths of the sides of a right triangle?
O 16, 32, 36
O 8, 12, 16
O 3,4, 5
O 9, 10,
Answer:
3,4,5
Step-by-step explanation:
Here, we want to select the set that could work and the sides of a right angled triangle
the correct answer is 3,4,5
These set are called a Pythagorean triple
This is because adding the square of the two smaller number will give the square of the largest number
What we are saying here is that by adding the square of 3 and 4, we get the square of 5 which illustrates that Pythagoras theorem works for the set
Triangle ABC has vertices A(-4, 1), B (-1, 3) and C (-1, 1). what would the vertices be if you graphed it’s reflection over the y axis
If this coordinates are reflected over the y-axis the resulting coordinate will be at A'(4, 1), B'(1, 3) and C'(1, 1)
Generally, if a coordinate (x, y) is reflected over the y-axis, the coordinate of the pre-image is (-x, y).
Note that the x-coordinate was negated while the y-coordinate remain the same.
Given the coordinate vertices of a triangle A(-4, 1), B (-1, 3) and C (-1, 1), if these coordinates are reflected over the y-axis the resulting coordinate will be at A'(4, 1), B'(1, 3) and C'(1, 1)

Work out the area of the trapezium.
Answer:
58.29 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (a + b) , substitute given values into formula
A = [tex]\frac{1}{2}[/tex] × 6.7 × (7 + 10.4)
= 3.35 × 17.4
= 58.29 cm²

A group of friends wants to go to the amusement park. They have $94.25 to
spend on parking and admission. Parking is $14.75, and tickets cost $13.25
per person, including tax. Write and solve an equation which can be used to
determine p, the number of people who can go to the amusement park.
Answer:
1) The equation to determine the the number of people who can go to the amusement park is 14.75 + 13.25·p = 94.25
2) The number of people who can go to the amusement park is people
Step-by-step explanation:
The given parameters are;
The amount the group of friends have to spend on parking and admission = $94.25
The cost parking = $14.75
The cost of tickets per person = $13.25
The variable we let to represent the number of people who can go to the amusement park be "p"
1) The equation that can be used to determine "p" is therefore, given as follows;
14.75 + 13.25·p = 94.25
2) Therefore, we have, by making "p" the subject of the above equation;
p = (94.25 - 14.75)/13.25 = 6
Therefore, the number of people who can go to the amusement park, p = 6 people.
Answer:
Answer: 6
Step-by-step explanation:
Equation: 13.25p+14.75=94.25
What are the solutions of (x - 3)(2x + 4) = 0
Step-by-step explanation:
(x - 3 ) (2x + 4) = 0
Either
x - 3 = 0
Therefore x = 3
Or.,
2x + 4 = 0
2x = - 4
x = - 4 /2
Therefore x = -2
Now the value of x is 3 or - 2.
Hope it will help :)♥
Answer:
x = 3 & x = -2
