The sides of a triangle are 10, 14, 18 what tie of triangle is it

1 answer:

5 0

Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be:
right if a² + b² = c²
аcute if a² + b² > c²
obtuse if a² + b² < c²

We have a=10, b=14 and c=18

a² + b² = 10² + 14² = 100 + 196 = 296
and
c² = 18² = 324

296 < 324 ⇒ obtuse triangle.

You have 65% of your homework left to complete. What decimal and fraction represent the amount of homework you have finished?

Maurinko [17]

Percentage of homework that is left to be completed = 65%
Then
The percentage of homework that is already done = (100 - 65) percent
   = 35 percent
   = (35/100)
   = 7/20
   = 0.35
So the amount of homework that has already been completed can be represented as 7/20 or o.35. Hope this is the answer you were looking for and i have helped you in this matter. Also i hope the procedure is easy enough for you to understand.

The graph below shows the height of a projectile t seconds after it is launched. If acceleration due to gravity is –16 ft/s2, wh

nika2105 [10]

Answer:

see attached

Step-by-step explanation:

The x-coordinate of the vertex is given by ...

x = -b/(2a)

for f(x) = ax^2 +bx +c.

We see that the vertex is at x = 1, and we are given a = -16. Then we can find "b" from ...

1 = -b/(2(-16))

32 = b

We know the y-intercept of the equation is 5 (the starting height), so the equation must be ...

h(t) = -16t^2 +32t +5 . . . . . matches the last choice

Find the midpoint of the segment with the given endpoints.

Ksju [112]

The mid-point for given endpoints is (4,3)

Step-by-step explanation:

a mid-point is the point on a line segment that divides it into two equal portions.

If (x1,y1) and (x2,y2) are the coordinates of vertices of a line segment, then mid-point is given by:

$M = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

given

(x1,y1) = (9,9)

(x2,y2) = (-1,-3)

$M = (\frac{9-1}{2}, \frac{9-3}{2})\\\\=(\frac{8}{2}, \frac{6}{2})\\\\=(4,3)$

The mid-point for given endpoints is (4,3)

James has a recipe that uses 1 1/2 cups of brown and 2 1/3 cups of flour to make 24 muffins. He has a total of 7 cups of sugar.

AURORKA [14]

Answer:

Part A: James needs 10 1/2 cups of sugar if he uses all 7 cups of flour

Part B: James will make 72 muffins if he uses all 7 cups of flour

Step-by-step explanation:

*I had an easier time figuring out part B before I figured out part A

PART B:

If the original recipe uses 2 1/3 cups of flour, and James has 7 cups of flour, I started off by dividing 7 by 2 1/3 to see how many times we can get 2 1/3 cups out of 7 cups. 7 divided by 2 1/3 = 3. Now that we know we can get 3 cups out of 2 1/3 cups, we need to multiply 3 by 24 to find out how many muffins James will get. 24 * 3 = 72

James will get 72 muffins by using 7 cups of flour.

PART A: Now we know that James is making 72 muffins. We need to find out how many cups of sugar James needs. To do that we can multiply 1 1/2 cups by 7. The product is 10 1/2 cups of sugar. Now we know that James needs 10 1/2 cups of flour if he uses all 7 cups of flour.

Hope this helps!!
