The figure shows a block of stone measures 8 cm by 5 cm by 2 cm and has a density of 2.5 g/cm3
what is the volume of the stone?
what is the mass of the stone?
Step-by-step explanation:
The volume of the stone = 8 × 5 × 2 = 80
Using density = mass / volume
So 2.5 = mass / 80
2.5 × 80 = mass
200 = mass
please give me brainliest answer
volume:
(8cm×5cm×2cm)=80cm³
I don't know the mass , sorry

why are 4^0 and (-4)^0 is equal to 1,while -4^0 is equal to -1
Step-by-step explanation:
According to the zero property of exponents, any number (other than 0) raised to the power of zero is always equal to 1.
The problem with this question is the simple fact that in this format it is confusing.
So, -(4^0) = -1 × (4^0) = -1x1 = -1
and, (-4)^0 =1

The number of seconds varies directly as the number of minutes. When 240 seconds have passed. 4 minutes have passed. If 420 seconds have passed , how many minutes have passed? ( help pls >.< )
Answer:
7 minutes.
Step-by-step explanation:
You can simply apply the well known rule if time: 60mins makes 1 hour,
or use proportion;
where x is the value you seek,
4=240
x=420
The relationship between 4 and 249 is 60 so,
420 divided by 60 equals 7 minutes.

Solve the quadratic equation by completing the square.
x^2 - 18x + 68 = 0
First, choose the appropriate form and fill in the blanks with the correct numbers.
Then, solve the equation. Round your answer to the nearest hundredth.
If there is more than one solution, separate them with commas.
Answer:
x = x = 9 ±[tex]\sqrt{13}[/tex] or x ≈ 12.61 or x ≈ 5.39
Step-by-step explanation:
x² - 18x + 68 Solve by completing the square.
x² - 18x = - 68
Now complete the square and add that number to both sides of the equation.
1/2 (of the coefficient of the x term)² = (1/2 · -18)² = 81 .
x² - 18x + 81 = -68 + 81
(x - 9) (x - 9) = 13 Now find the square root of both sides
[tex]\sqrt{(x - 9)(x - 9)}[/tex] =[tex]\sqrt{13}[/tex] Solve
x - 9 = ±[tex]\sqrt{13}[/tex] Solve for x
x = 9 ±[tex]\sqrt{13}[/tex]
x = 9 + [tex]\sqrt{13}[/tex] or x = 9 - [tex]\sqrt{13}[/tex]
x ≈ 12.61 or x ≈ x 5.39

Suppose f(x) = 3x*2 - 2x
Find f(-4)
Answer:
f(- 4) = 56
Step-by-step explanation:
Substitute x = - 4 into f(x) , that is
f(- 4) = 3(- 4)² - 2(- 4) = 3(16) + 8 = 48 + 8 = 56

In the diagram below, angle PNO is congruent to angle PQR. RO = 7.1, PQ = 11.1, and PR= 8.9. Find the length of QN. Round your answer to the nearest tenth if necessary.
Answer:
8.9
Step-by-step explanation:
7.1/8.9=Qn/11.1
QN = 8.9
{ Parallel lines divide in proportion to their segments }
The solution is 8.9
The length of the side of the triangle PNO is QN = 8.9
What are similar triangles?
If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be ΔPNO
Let the second triangle be ΔPQR
Now , ΔPNO ≅ ΔPQR
And , The corresponding sides of similar triangles are in the same ratio
So , substituting the values in the equation , we get
RO / PR = QN / PQ
On simplifying the equation , we get
7.1 / 8.9 = QN / 11.1
Multiplying both sides of the equation by 11.1 , we get
QN = ( 7.1 x 11.1 ) / 8.9
The value of QN will be
QN = 8.85
Rounding the value of QN to the nearest tenth , we get
QN = 8.9
Therefore , the value of QN is 8.9
Hence , The length of the side of the triangle PNO is QN = 8.9

Nick has 4 times as many partners as Gabriel, Leo has half as many partners as Nick.
Altogether, they have 28 partners. Explain how many partners Gabriel has.
Gabriel has 4 partners.
When you take the 4 and multiply it by 4, you get 16 where you'd take half of the 16 and add it to it. So you'd have 16 + 8 where it equals 24 and then add the original 4 and you get 28.
