HELP 276.5 divided by 7.9.

Answer:

23.6

Step-by-step explanation:

[tex]c=2\pi r[/tex]

The diameter of the cirle is 7.5 m. To find the radius you would take half of the diameter.

7.5 / 2 = 3.75

[tex]c=2\pi 3.75[/tex]

Then you multiply them

your answer is

23.5619

then you round

23.6

Hope this helps!

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:

760 m

Step-by-step explanation:

You can draw a right triangle.

For the angle of 70°, 276 m is the adjacent side.

The heigh of the building above 1.66 m is the opposite side.

tan x = opp/adj

tan 70° = h/276

h = tan 70° × 276

h = 758.3

h is the height above 1.66 m.

height = 758.3 m + 1.66 m = 759.96 m

Answer: 760 m

The rectangle is symmetrical about the y-axis. Then both the figures are rectangles and all the rectangles are similar. Then the correct option is B.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

The rectangle EFGH is dilated of the rectangle ABCD with a center of the dilation at the origin.

From the figure, it is clear that the rectangle is symmetrical about the y-axis. Then both the figures are rectangles and all the rectangles are similar.

Hi

Step-by-step explanation:

Based on Rachel's work, we can deduce and conclude on the following: options A, C and E.

Based on Rachel's work shown in the image attached below, we can deduce and conclude on the following:

The function is continuous because for every hour given, there is always a value for the cups of juice. Thus, its graph would be linear and have a straight line.

Also, the scenario is represented by a linear function because the rate of change is constant. Lastly, for every additional hour, 53 cups of juice are poured.

In conclusion, time represents the independent variable while number of cup of juice is an independent variable.

Answer:

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

correct on edge

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:

[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]

Step-by-step explanation:

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.

Answer:

50%

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]
