Answer: $1,560
Step-by-step explanation:
Assume the computer's price is x.
This means that expressing the printer in terms of x would be:
= 30% * x
= 0.3x
These two put together represent the cost of $2,028
Expression is:
x + 0.3x = 2,028
1.3x = 2,028
x = 2,028/ 1.3
x = $1,560
Computer was $1,560
Printer was therefore:
= 1,560 * 30%
= $468

A rectangle has an area of 235.2m squared. One of the sides is 2.8m in length. work out the perimeter of the rectangle, please?
Answer:
P = 173.6 mSteps:
given:
A = 235.2 m²
S1 = 2.8 m
S2 = A/S1
S2 = 235.2/2.8
S2 = 84 m
P = 2(S1+S2)
P = 2(2.8+84)
P = 2 × 86.8
P = 173.6 m

a French essay about your garden
Answer:
Aujourd'hui, je cherchais l'esthétique du jardin et j' trouvai une photo d'un jardin qui ressemble à mon jardin. C'était grand avec des fleurs différentes toutes alignées dans des pots. Il y avait aussi un coin salon avec des chaises flottantes et une petite table orange à côté. Il y avait une allée qui menait à un petit jardin plein de légumes et de fruits plantés. Je sors dans mon jardin chaque fois que je me sens étouffé de ma maison, cela me fait me sentir rafraîchi et heureux.

The correct answer to the exercise is:
Surface area of a circle = 633.1 [tex]mm^{2}[/tex]Step-by-step explanation:
To obtain the surface area of a circle, you can use the formula:
Surface area of a circle = π * [tex]r^{2}[/tex]Where:
π = 3.14 (the exercise give this)r = Circle radius.How you can see, in the picture gives you a straight line that passes through the circle side by side, the circle radius is half of that value, then:
r = 28.4 mm / 2r = 14.2 mmNow, we can replace the values in the first formula:
Surface area of a circle = π * [tex]r^{2}[/tex] Surface area of a circle = 3.14 * [tex](14.2 mm) ^{2}[/tex]Surface area of a circle = 3.14 * 201.64 [tex]mm^{2}[/tex]Surface area of a circle = 633.1496 [tex]mm^{2}[/tex]Surface area of a circle = 633.1 [tex]mm^{2}[/tex] (rounded to the nearest tenth).Use the graph to find the solutions of –12x2 – x + 4 = 0.
Answer:
x=2, x= -4
Step-by-step explanation:
Move all the terms to the left side and set equal to 0.Then set each factor equal to 0.
The solution to the considered equation -12x^2 -x + 4 = 0 is x = -4 and x = 2 (the points where the curve of f(x) = -12x^2 -x + 4 touches x-axis).
What is x-intercept of a function?The x-intercept of a function of variable x ( y = f(x) ) form is an intersection fo the x-axis and the curve of the function.
The x-intercept for a function y = f(x) is a solution to the equation f(x) = 0 becuase at that value of x, the function f(x) lies on x-axis, where y is 0. Values of x-intercept for a function f(x) are also called roots or solution of f(x) = 0 equation.
So, if we take:
[tex]f(x) = -12x^2 -x + 4[/tex]
then, the x-intercept for a function y = f(x) is a solution to the equation f(x) = 0, which is the equation [tex]-12x^2 -x + 4 = 0[/tex]
The x-intercept is visible from the graph being at x = -4 and x = 2
Thus, the solution to the considered equation [tex]-12x^2 -x + 4 = 0[/tex] is x = -4 and x = 2

When rolling a die and flipping a penny, what is the P(4, H)? Make a table or diagram to help get your result.
P(4, H) =
Answer:
P(4, H) = 1/12
Step-by-step explanation:
Here we have two events, let's count the number of outcomes in each one of them.
Rolling a die.
Here we have 6 possible outcomes (1, 2, 3, 4, 5, 6)
Flipping a penny.
Here we have two possible outcomes (Heads = H, Tails = T)
The total number of outcomes in the combined event will be equal to the product between the number of outcomes for each event, so we have a total of:
6*2 = 12 events, that have the same probability.
We want to find P(4, H)
This is the probability of rolling a 4 in the die and heads in the penny.
This is one outcome, and we have a total of 12 outcomes (all with the same probability)
Then the probability of each event is equal and should be 1/12 (one over the number of possible outcomes)
We can conclude that the probability P(4,H) = 1/12

Any horizontal lines on a distance time graph represent a moment where you are still, so that rules out graph 4 and graph 3. Because Ralph is at a constant speed, the gradient of the line won’t change, meaning the answer has to be Ralph walked to Sherwood at a constant speed.

Step-by-step explanation:
12. 21 and 22 are supplementary. The measure of 1 is three times the measure of 2. What is m2?
a. 30°
b. 45°
c 54
d.55
e. 135
Answer:
The measure of angle 2 is 45 degrees
Step-by-step explanation:
Mathematically, when two angles are supplementary, the sum of these angles will be equal to 180 degrees
Let the measure of angle 2 be x
The measure of angle 1 is 3 times this and that will be 3 * x = 3x
The sum of both will be 180
x + 3x = 180
4x = 180
x = 180/4
x = 45

A student designed this sculpture. Using the dimensions on the sculpture, find the dimensions of each rectangular prism. Then calculate the volume of each prism.
Answer:
Prism Y
[tex]Height = 12in[/tex]
[tex]Length = 6in[/tex]
[tex]Width = 4in[/tex]
[tex]Volume = 288in^3[/tex]
Prism Z
[tex]Height = 18in[/tex]
[tex]Length =10in[/tex]
[tex]Width = 10in[/tex]
[tex]Volume = 1800in^3[/tex]
[tex]Total = 2088in^3[/tex]
Step-by-step explanation:
Given
See attachment for sculpture
Solving (a) The dimension and volume of Y
From the attachment
[tex]Height = 18 - 6[/tex]
18 in is the height of Z and 6in represents the length (height) of the unoccupied space by Y
So:
[tex]Height = 12in[/tex]
[tex]Length = 16 - 10[/tex]
16 in is the total length of the sculpture and 10 in represents the length of Z
So:
[tex]Length = 6in[/tex]
[tex]Width = 10 - 6[/tex]
10 in is the width of Z and 6in represents the length (width) of the unoccupied space by Y
So:
[tex]Width = 4in[/tex]
Hence, the dimension of Y is:
[tex]Height = 12in[/tex]
[tex]Length = 6in[/tex]
[tex]Width = 4in[/tex]
Volume is then calculated as:
[tex]Volume = Length * Width * Height[/tex]
[tex]Volume = 12in * 6in * 4in[/tex]
[tex]Volume = 288in^3[/tex]
Solving (b) The dimension and volume of Z
As identified in (a), the dimensions of Z are:
[tex]Height = 18in[/tex]
[tex]Length =10in[/tex]
[tex]Width = 10in[/tex]
Volume is then calculated as:
[tex]Volume = Length * Width * Height[/tex]
[tex]Volume = 18in * 10in * 10in[/tex]
[tex]Volume = 1800in^3[/tex]
Solving (c): Total volume of the sculpture.
To do this, we simply add up the volumes of Y and Z.
So, we have:
[tex]Total = 288in^3 + 1800in^3[/tex]
[tex]Total = 2088in^3[/tex]
