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

From her eye, which stands 1.66 meters above the ground, Deondra measures the
angle of elevation to the top of a prominent skyscraper to be 70°. If she is standing at
a horizontal distance of 276 meters from the base of the skyscraper, what is the
height of the skyscraper? Round your answer to the nearest tenth of a meter if
necessary.
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

Solve the system by substitution.
4x + 2y = 10
x − y = 13
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":-

0.02 mph
180 mph
45 mph
Answer:
45 mph
Step-by-step explanation:
It took the car 4 hours to travel 180 miles
Then
It took the car 4/4 hours to travel 180/4 miles
Since 4/4 = 1 and 180/4 = 45
Then
It took the car 1 hours to travel 45 miles
Therefore ,the car was it going at 45 mph

Step-by-step explanation:
What is the volume of the figure below if a = 8 units and b = 6 units?
A.
536 cubic units
B.
704 cubic units
C.
256 cubic units
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.
what is the solution set of 2/5 (x+4) -3/5 (2x+3) = 2/5(2-x)-1
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).

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]

a square coffee table has an area of 196 square inches.what is the perimeter
Answer:
56 in
Step-by-step explanation:
Square ....so each side is = x
x * x = area = 196
x^2 = 196
x = sqrt (196) = 14 in
perimeter = x + x + x + x = 56 in
Answer:
56 inches
Step-by-step explanation:
Given,
Area of square = 196 square inches
To find : Perimeter of the square = ?
Formula : -
Area of square = side²
side² = 196
= 14 x 14
side² = 14²
side = 14 inches
Formula : -
Perimeter of the square = 4 x side
perimeter of the square
= 4 x 14
= 56 inches
A cylindrical tank is having water pumped in at a
rate of 45 liters/minute and is releasing water at
the bottom at a rate of 25 liters/minute. After five
minutes, what is the net change in the volume of
the water in the tank in liters?
The net change in the volume of the water in the tank in liters would be 100 liters.
How to find the change in volume?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

Is rectangle efgh the result of a dilation of rectangle abcd with a center of dilation at the origin? why or why not? yes, because corresponding sides are parallel and have lengths in the ratio four-thirds yes, because both figures are rectangles and all rectangles are similar. no, because the center of dilation is not at (0, 0). no, because corresponding sides have different slopes.
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.
What is a rectangle?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.
