A cube has a surface area of 600 square meters. What is its volume?
A.600 m³
B.300 m³
C.100 m³
D.1000 m³
Answer: D, 1000 m^3.
Step-by-step explanation: We can find the volume by breaking down the surface area.
The formula for the surface area of a cube is 6*x^2 with x being the side length and 6 being the number of sides. Thus we can form the equation as follows:
600 = 6*x^2 - original equation
x^2 = 100 - divide both sides by 6
x = 10 - square root both sides
Thus, the side length is 10.
We can find the volume with the formula l*w*h or, in this case, x^3.
We know that x = 10, so x^3 must be 1000.
Thus, the answer is D, 1000 m^3.

What is the value of x in the equation 6(x +11)= -300?
Answer:
-61
Step-by-step explanation:
We use the distributive property to distribute 6 to both x and 11. This gives 6x+66=-300. Subtracting both sides by 66 gives 6x=-366. Dividing both sides gives x=-61.

Solve the system of linear equations by substitution x-y=2 x+2y=5
Answer:
x = 3
y = 1
Step-by-step explanation:
x - y = 2 ---------------(I)
x + 2y= 5 ----------------(II)
x - y = 2
x = 2 + y _________(III)
Substitute x = 2 + y in equation (II)
2 + y + 2y = 5 {combine like terms}
2 + 3y = 5
3y = 5 -2
3y = 3
y = 3/3
y = 1
Substitute y = 1 in equation (III)
x = 2 + 1
x = 3
0.75x - y = - 2.1
0.6y 2.4x +9
Answer:
4x-3

Salma used a photocopier to dilate the design for a monorail track system. The figure shows the design and its photocopy: Two irregular quadrilaterals ABCD and EFGH are drawn. EFGH is the photocopy of design ABCD. AB measures 15 meters, DC measures 17 meters. No dimensions are shown on EFGH. The ratio of AD:EH is 1:2. What is the length, in meters, of side GH on the photocopied image? 15 17 30 34
Answer:
The answer is 34
Step-by-step explanation:
The ratio of AD:EH is 1:2, so therefore the other line segments have the same ratio. Using this logic, we see that DC is equal to 17 m, and we need to find GH. All we do now is double the measurement of DC since the ratio of the two shapes is 1:2.
Therefore, 17 * 2 = 34
Answer:
34

Solve the proportion (w+12)/(3w+5)=3/4
Answer:
[tex]w=6.6[/tex]
[tex]18.6:24.8::3:4[/tex]
Step-by-step explanation:
[tex]As\ we\ know\ that,\\(w+12):(3w+5)::3:4\\By\ the\ proportion\ method\ of\ multiplying\ the\ means\ and\ the\ extremes,\\we\ get,\\(w+12)*4=3*(3w+5)\\4w+48=9w+15\\48-15=9w-4w\\33=5w\\[/tex]
[tex]w=33/5\\w=6.6[/tex]
[tex]By\ substituting\ the\ value\ of\ w\ in\ the\ proportion. you\ get:\\(6.6+12)/(3*6.6+5)=3/4\\18.6/24.8=3/4\\18.6:24.8::3:4[/tex]

A rhombus, which is a quadrilateral with 4 equal sides, is plotted on the coordinate plane. The coordinates of the vertices are: (−1,0), (4,0), (2,4), and (7,4). How long is each side of the rhombus?
Answer:
Each side of the Rhombus is 5 units
Step-by-step explanation:
Since the sides of a rhombus area all equal in length;
Then, the length of a side is enough to get the lengths of the other sides
Mathematically, finding the distance between two points out of what we are given will be enough to get the measure of one of the side of the rhombus
We apply the distance formula appropriately to get the distance between the side of the Rhombus
D = √(x2-x1)^2 + (y2-y1)^2
let us use the points (-1,0) and (4,0)
D = √(4 + 1)^2 + (0-0)^2
D = √25
D = 5

Find the area of the sector:
A=
yd? (Round to one decimal place)
210°
16 yd
Answer:
469.1 yd²
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × [tex]\frac{210}{360}[/tex]
= π × 16² × [tex]\frac{21}{36}[/tex]
= 256π × [tex]\frac{7}{12}[/tex]
≈ 469.1 yd² ( to 1 dec. place )

3) 9x² - 5x-9
4) 9x2 - 13x - 9
Answer:
3) 9x² - 5x - 9
Step-by-step explanation:
Combine like terms
5x² - 9x + 3 + 4x² + 4x - 12 = 5x² + 4x² - 9x + 4x + 3 - 12
= 9x² - 5x - 9

A chemist is using 353 milliliters of a solution of acid and water. If 14.7 of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth
Answer:
The amount of Acid in a solution = 51.9 millimeters
Step-by-step explanation:
Given that the total amount of solution of acid and water = 353 milliliters
Acid percentage = 14.7%
Thus, in order to determine the amount of acid, all we need is to multiply 353 with 14.7% or 0.147.i.e
Amount of Acid = 14.7% of 353
= 0.147 × 353
= 51.9 millimeters
Therefore, the amount of Acid in a solution = 51.9 millimeters
