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

Multi step problem 4/7w = 4.2
Answer:
7.35
Step-by-step explanation:
4/7w=4.2
multiply both sides by 7
24/7w=29.4
simplify
4w=29.4
divide both sides by 4
w=7.35
Answer:
w equals 7.35
Step-by-step explanation:
7 times 4/7w = 4.2 times 7
4w = 29.4
Divide: 4w/4 = 29.4/4
w = 7.35
Jessica plants a seed 3 1/2 inches below the ground. The plants grows from 15 3/4 inches . What is the height of the plant above ground?
Answer:

A basketball player made 12 out of 15 free throws she attempted.She wants to know how many consecutive free throws she would have to make to raise the percent of successful free throws to 85%. Write an equation to represent this situation.
Answer:
(12 + x)/(15 + x) = 85/100
Step-by-step explanation:
12/15 = 0.8
She currently has an 80% rate.
To raise it, she needs to make x shots. Since she makes all x shots, we add x to both the number of shots made and attempts.
She will make 12 + x shots in 15 + x attempts.
We want that rate to be 0.85 which is the same as 85%.
(12 + x)/(15 + x) = 85/100
(12 + x)/(15 + x) = 17/20
20(12 + x) = 17(15 + x)
240 + 20x = 255 + 17x
3x = 15
x = 5
Answer:
The equation is (12 + x)/(15 + x) = 85/100.

Answer:
The slope of Function A is less than the slope of Function B.
Step-by-step explanation:
Using the slope formula:
m = (y2 - y1)/(x2 - x1)
and the following ordered pairs from Function A:
(x1, y1) = (-5, -3)
(x2, y2) = (-10, -8)
m = (y2 - y1)/(x2 - x1)
[tex]m = \frac{-8 - (-3)}{-10 - (-5)} = \frac{-8 +3}{-10+5} = \frac{-5}{-5} = 1[/tex]
Since Function A's slope = 1, and Function B's slope = 4, then it means that the slope of Function A is lesser than the slope of Function B.

Answer:
[tex]\frac{y - 3}{4}[/tex]
Step-by-step explanation:
To make x the subject, first, subtract 3 from both sides:
y = 4x + 3 → y - 3 = 4x
Next, divide both sides by 4 to get x on its own:
y - 3 = 4x → (y - 3)/4 = x

A)4/3
B)7/8
C)-7/8
D)-4/3

Answer:
C) - 7/8Step-by-step explanation:
Average rate of change is:
[f(7) - f(5)]/(7 - 5)Find the values and substitute into expression:
f(7) = (7 + 4)/(7 - 3) = 11/4f(5) = (5 + 4)/(5 - 3) = 9/2 = 18/4Find the rate of change:
(11/4 - 18/4)/2 = (-7/4)/2 = - 7/8Correct choice is C

There's a big soccer game next month, and Juan has purchased 3 tickets for himself and his siblings. He spent 53 dollars.
Rosie wants to take her family also, but knows her parents and some cousins will want to attend as well. She knows she will have to purchase 9 tickets. Estimate approximately how much money Rosie will likely have to spend on the tickets. Explain your reasoning below.
Answer:
53 divided by 3 would be $17.66
so 17.66 times 9 would be $158.94
Answer:
158.4 dollars
Step-by-step explanation:
so first of all the three tickets were 53 dollars so we divide the dollars and the no of tickets like this 53÷3 = 17.6 dollars
so since each ticket is 17.6 dollars now we know that Rosie wants to purchase 9 tickets so we will multiply the no of tickets by dollars per ticket like this
9×17.6= 158.4 dollars
and 158.4 is your answer

Step-by-step explanation:
shape BCD is an isosceles triangle meaning the base angles will be the same.
CA is a straight line meaning that it is 180
the sum of angles in a triangle always is 180
so
180-36= 144
to find x you need to half 144 as it is the sum of the base angles of the isosceles triangle.
144/2= 72
x=72
the angle just below y is also 72.
as CA is a straight line,
180-72= 108 giving you the answer for y
y= 108
so to make the answer clear
x= 72
y= 108
hope that helped! :)

Answer:
C.
Step-by-step explanation:
Answer: C
Step-by-step explanation:
Say we had 2 fractions:
2/4 & 3/6
and we were trying to find out if they were proportional.
An easy way to do this is to divide the numerator of the second fraction by the numerator of the first fraction, then multiply what you get by the denominator of the first fraction. If your final number equals the denominator of the second fraction, then the two fractions are proportional.
Let me demonstrate:
2/4 and 3/6
1. 3 ÷ 2 = 1.5
2. 1.5 × 4 = 6
3. 6 = 6
Therefore, these fractions are proportional.
Let's try another problem:
4/5 and 10/19
1. 10 ÷ 4 = 2.5
2. 2.5 × 5 = 12.5
3. 12.5 ≠ 19
Therefore, these fractions are not proportional.
Hope this helps!
what is 9x² -4 in factored form. i just need more help understanding how to do this.
Answer:
the factored form of 9x²-4 is (3x-2)(3x+2)
is −4[3(x−7)] and 6(14−2x) equiviant
Answer:
Yes.
Step-by-step explanation:
Set the equations equal to each other to determine their equality.
-4[3(x - 7)] = 6(14 - 2x)
Distribute the 3 and the 6 into their respective parenthesis.
-4[3x - 21] = 84 - 12x
Distribute the -4 into the brackets.
-12x + 84
Rearrange the equations.
84 - 12x = 84 - 12x
Since the equations come out to be the same thing on both sides so that any value satisfies it, the equations are equivalent.
