Answer:

RV = 49 units

Step-by-step explanation:

in parallelogram RSTU , the diagonals bisect each other, then

TV = RV , that is

3y - 17 = y + 27 ( subtract y from both sides )

2y - 17 = 27 ( add 17 to both sides )

2y = 44 ( divide both sides by 2 )

y = 22

Then

RV = y + 27 = 22 + 27 = 49 units

Phillipe has 320 pieces of

tankabanditka [31]

The number of candies that will be left over after giving everyone an equal amount is equal to 23.

Given the following data:

Total number of candy = 320 pieces

Number of classmates = 27 classmates

To calculate the number of candies that will be left over after giving everyone an equal amount:

In this exercise, you're required to determine the number of candies Phillipe would have as left over after giving everyone in his class an equal amount of candies.

<h3>How to solve this word problem.</h3>

Thus, we would find the number of times 27 would divide 320 without any remainder.

$\frac{320}{27} = 11 \frac{23}{27}$

From the mixed fraction, we can deduce that the remainder is 23.

Therefore, the number of candies that will be left over after giving everyone an equal amount is equal to 23.

I would like to know the process for dis ive been struggling on them. i tried to ask the teacher but they made it more confusing

Dafna11 [192]

Answer:

31.177 m

Step-by-step explanation:

So the formula of a hexagon is Area = (3√3 s^2)/ 2

s = side in this problem. A hexagon is made up of 6 equilateral triangles, so the distance from the center is equal to each of the sides.

For this problem, plug and chug. Plug your knowns into equation and you will find the answer.

s^2 = (2√3)^2 = 12

Area = (3√3 x 12)/2 = 31.1769 m

I am not sure how many decimals you are supposed to round, probably 3 so in that case 31.177 m

Find the vertex of the parabola.

Gnesinka [82]

Answer:

The vertex is (3,4)

Step-by-step explanation:

f (x) = x^2 - 6 x + 13

Completing the square

-6/2 = -3 and squaring it = 9

= x^2 -6x +9 +4

= ( x-3) ^2 +4

The equation is now in vertex form

a( x-h) ^2 +k

where the vertex is ( h,k)

The vertex is (3,4)
