Answer:

155

Step-by-step explanation:

calculate the areas of 2 rectangles

method A

one rectangle with lengths 8 and 10

the other 15 and 5

so 8x10 + 15x5 = 80 + 75 = 155

method B

one traingle with lenghts 5 and 7

the other 15 and 8

so 15x8 + 5x7 = 120 + 35 = 155

Answer:

There would be a 56% increase

Step-by-step explanation:

We need to find the amount of change before we can find the percent of change. We'll take the greater value, 78, and subtract the lesser value, 50. 78 - 50 = 28. We then take this amount of change and put it over the original amount, Percent of change = Amount of change/ original amount or for this problem, 28/50. We then use that as a division equation for 28 divided by 50. 28 divided by 50 = 0.56. Finally we move the decimal to the right two times and we can then find the percentage increase.

Answer: 9

Step-by-step explanation:

super easy

basically do 15-5 which is 10

thats the hypotenuse side

now apply pythegorean theorem: 5 squared + x squared= 10 squared

25+ x squared=100

x squared=75

x approxiametly equals 9

Answer:

180 bestie

Step-by-step explanation:

The magnitude of rotational symmetry of the given ellipse is angle 180°.

Suppose that the major axis is of the length 2a units, and that minor axis is of 2b units, and let the ellipse is centered on (h,k) with major ellipse parallel to x-axis,

then the equation of that ellipse would be:

[tex]\dfrac{(x-h)^2}{a^2} + \dfrac{(y-k)^2}{b^2} =1[/tex]

Coordinates of its foci would be:  [tex](h \pm c, k)[/tex] where   c^2 = a^2 - b^2

Let the magnitude of rotational symmetry of the given ellipse is angle θ.

Measure of angle θ is a straight line.

Measure of angle θ = 180°

Therefore, with a rotation of 180° ellipse will overlap itself.

Answer:

The slope is:

[tex] \frac{1}{7} [/tex]

Step-by-step explanation:

⁕ Remember that slope formula is:

[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]

⁕ Let's plug in and solve.

[tex]m =  \frac{ 2 - 1}{4 - ( - 3)}  =  \frac{ 1}{ 7}[/tex]

Therefore, the slope is:

[tex] \frac{1}{7} [/tex]

Answer:

60 seconds, 7715 feet

Step-by-step explanation:

Plane A and B start out 615 feet apart, and we find this by subtracting the height of plane A from plane B, getting 5000-4385=615. Now we have to find how many more feet of altitude plane A is gaining per second over plane B.

To find this we subtract 45.25 from 55.5 and get 10.25 feet per second. Now to find out how many seconds until they'll be at the same altitude we simply divide 615 by 10.25, getting 60 seconds.

For the second part, to find the altitude at this point, we simply multiply the altitude gain of one of the planes per second by the time of 60 seconds to get how much altitude they gained over that time, and add it to the starting altitude. Doing this with plane B we get 45.25*60=2715, and we add that to 5000 to get the final answer of 7715.

Answer:

k = 1

Step-by-step explanation:

Given that,

[tex]f(x) = x^3 +kx + 2[/tex]

If (x+1) is a factor of (x), we need to find the value of k.

Using remainder theorem to find it.

Put (x+1) = 0

x = -1

Put x = -1 in equation below.

[tex]x^3 + kx + 2=0\\\\(-1)^3+k(-1)+2=0\\\\-1-k+2=0\\\\1-k=0\\\\k=1[/tex]

So, the value of k is 1.

Answer:

x-intercept (6,0)

y-intercept (0,-4.5)

Step-by-step explanation:

the x-intercept will be when y=0

and the y-intercept will be when x=0

so

[tex]y=0\\\\-6x+8(0)=-36\\\\-6x=-36\\\\x=6[/tex]

so the x intercept will be at (6,0)

[tex]x=0\\\\-6(0)+8y=-36\\\\8y=-36\\\\y=-\frac{9}{2}\\\\y=-4.5[/tex]

so the y intercept will be at (0,-4.5)
