Answer:

24 balms

Step-by-step explanation:

2 hours is 120 minutes

120 minutes / (5 minutes/balm)  = 24 balms

The net change in the volume of the water in the tank in liters would be  100 liters.

We can calculate the released in released with the released between the water released from the water released .

Quantity of water pumped in per minute = 45 liters

Quantity of water released per minute = 25 liters

Number of minutes = 5 minutes

Total water pumped in = 45 liters × 5 minutes

= 225 liters

Total water released = 25 liters × 5 minutes

= 125 liters

Net change in the volume of the water in the tank in liters

= Total water pumped in - Total water released

= 225 liters - 125 liters

= 100 liters

Answer:

704 cubic units

Step-by-step explanation:

First let's calculate the volume of the cube. The formula to calculate the volume of a cube is V = a^3, a being the edge length of the cube. So we need to cube the value of a, which is 8. 8 cubed is 512 cubic units.

Now we need to calculate the volume of the triangular prism. The formula to calculate the volume of a cube is V = 1/2b * a * h, a being the side edge length of the prism, b being the height of the triangular side, and h being the base edge length of the triangular side, if that makes any sense (easier to explain visually). h and a are equal to the given a, which is 8 in this case. And b in the formula is equal to b in the given problem. So we substitute the values into the formula: V = (1/2*6) * 8 * 8 = 3 * 64 = 192 cubic units.

Now we take the sum of both of the figures:

512 + 192 = 704 cubic units.

Step-by-step explanation:

if y = 0

0 = -2x + 4 _ eq 1

0 - 4 = -2x

-4 = -2x

divide through by 2

x = -4 ÷ -2

x = 2

if x = 0

y = -2(0) + 4_ eq 2

y = 0 + 4

y = 4

Answer:

5 for both.

Step-by-step explanation:

Multiplying exponents rule with like bases;

Add powers with like bases.

So, if we look at x to the power of the blank multiplied by x to the power of 5, we know that 5 added to that unknown/blank power would equal in 10(using the multiplication of exponents rule), because in the results it says x^10.

Thus,

x to the power of __       ·       x to the power of 5 = x to the power of 10

And, 5 would make a solution for the blank, because;

x to the power of 5      ·       x to the power of 5 = x to the power of 10, which is true because their exponents added together would be 10 → (5 + 5).

Now, if we look at y to the power of 3 multiplied by y to the power of the blank, we know that 3 added to the unknown/blank power would equal in 8(using the multiplication of exponents rule) because in the results says y^8.

Thus,

y to the power of 3       ·       y to the power of __ = y to the power of 8

And, 5 would make a solution for the blank, because;

y to the power of 3       ·       y to the power of 5 = y to the power of 8,  which is true because their exponents added together would be 8 → (3 + 5).

Overall you're basically just multiplying all those exponents together.

Answer:

[tex]\boxed{\tt (6,-7)}[/tex]

Step-by-step explanation:

[tex]\tt 4x + 2y = 10\\x - y = 13[/tex]

First Let's solve for x in x-y=13

[tex]\tt x-y=13[/tex]

Add y to both sides:

[tex]\tt x=13+y[/tex]

Now, Substitute x=13+y into 4x+2y=10:-

Let x=13+y

[tex]\tt 4(13+y)+2y=10[/tex]

[tex]\tt 52+6y=10[/tex]

Now, let's solve for y in 52+6y=10:-

[tex]\tt 52+6y=10[/tex]

Subtract 52 from both sides:-

[tex]\tt 6y=10-52[/tex]

[tex]\tt 6y=-42[/tex]

Divide both sides by 6:-

[tex]\tt \cfrac{6y}{6} =\cfrac{-42}{6}[/tex]

[tex]\boxed{\tt y=-7}[/tex]

Now, we'll Substitute y=-7 into to x=13+y to find "x":-

[tex]\tt x=13+y[/tex]

[tex]\tt x=13+-7[/tex]

Answer:

19.6

Step-by-step explanation:

A = πr²

A = (3.14159)(2.5 in.)²

A = 19.6 in.²

Step-by-step explanation:

2/5(x+4) - 3/5(2x+3) = 2/5(2-x)-1

2/5(x+4)-3/5(2x+3) = 2/5x-1/1(2-x)

2/5(x+4)-3/5(2x+3) = -2/5(2-x)

2/5x+8/5 - 6x/5 + 9/5 = -4/5 - (-2x/5) (-x- = +)

2x/5 + 8/5 - 6x/5 + 9/5 = -4/5 + 2x/5

(take like terms)

2x/5 - 6x/5 - 2x/5 = -4/5 - 9/5 - 8/5

( Find their L.C.M ) (5 is the LCM)

2x - 6x -2x / 5 = -4 - 9 - 8 / 5

-10x / 5 = -13 / 5

( cross multiply)

-50x = -65

x = -65/50

x = -1.3 ( decimal)

or x = 13/10 (improper fraction)

or x = 1 ³/10 ( mixed fraction).

Hope this helps.

Good luck.

Answer:

y = 3/5x + 1

Step-by-step explanation:

Formula:

y - y1 = m(x - x1)

Plug in:

y - (-2) = 3/5(x - (-5))

Two negatives make a positive:

y + 2 = 3/5(x +5)

Distribute 3/5 to (x + 5):

y + 2 = 3/5x + 3

Get y by itself by - 2:

y = 3/5x + 1

x = -5/2  + root(33)/2   or   x = -5/2 - root(33)/2

Step-by-step explanation:

ok so your computer is

saying:

x^2  + 5x = 2

and takes the 5 divides it by 2  and squares the result

x^2  + 5x  +  25/4    =   2 + 25 /4   but then   replaces a trinomial with a binomial

(x + 5/2)^2  =  2 + 25/4 =  33/4

solving

x = -5/2  + root(33/4)   or   x = -5/2 - root(33/4)

or

x = -5/2  + root(33)/2   or   x = -5/2 - root(33)/2

If two solids are similar with a scale factor of a/b, then the surface areas are in a ratio of [tex]\rm \left (\dfrac{a}{b } \right )^2[/tex].

If two solids are similar with a scale factor of a/b, then the volumes are in a ratio of [tex]\rm \left (\dfrac{a}{b } \right )^3[/tex].

Two shapes are similar if all their corresponding angles are congruent and their corresponding sides are proportional.

Two solids are similar if they are the same type of solid and their corresponding radii, heights, base lengths, widths, etc. are proportional.

When two shapes are similar in two dimensions, the ratio of their areas is the square of the scale factor.

A comparable relationship holds in three dimensions as well.

Surface Area Ratio: If two solids are similar with a scale factor of a/b, then the surface areas are in a ratio of [tex]\rm \left (\dfrac{a}{b } \right )^2[/tex].

Volumes of Similar Solids; Just like surface area, volumes of similar solids have a relationship that is related to the scale factor.

Volume Ratio: If two solids are similar with a scale factor of a/b, then the volumes are in a ratio of [tex]\rm \left (\dfrac{a}{b } \right )^3[/tex].

Step-by-step explanation:

The end goal here is to find the total area of the entire figure from the center to the outer radius D. Then take the ratio of region B with respect to the total area, which will give you the probability of landing in the area B.

Circle A has a radius of 4. Circle B has a radius of 8. Circle C has a radius of 12. Circle D has a radius of 16. Therefore, the total area of the dartboard is given by:

[tex]A_{total}=\pi r^2=\pi (16)^2=256\pi[/tex]

The area of the region B can be found by thinking of region B as a shaded region between two concentric circles A and C. The area of the circle C is given by:

[tex]A_C=\pi r^2=\pi (12)^2=144\pi[/tex]

The area of circle A is given by:

[tex]A_A=\pi r^2=\pi (4)^2=16\pi[/tex]

Therefore the area of region B would be:

[tex]A_B=144\pi -16\pi =128\pi[/tex]

Finally, the probability of landing in region B would be:

[tex]P=A_B/A_{total}=128\pi /256\pi =0.5[/tex]
