9514 1404 393

Answer:

  24x

Step-by-step explanation:

The total length of all vertical segments is 5x·2 = 10x.

The total length of all horizontal segments is (3x+4x)·2 = 14x.

Then the total length of all perimeter segments is ...

  10x +14x = 24x . . . . perimeter of the figure

A company makes Poppy Lapel Pins.
Blizzard [7]

Answer:

1000 less 35% == 650

so 250 given to charity

total cost making the pins was 1000x 1.10 = 1100

so you need to find 60 percent of 650 =390

and 40 percent of 650 = 260

so then you need to find the cost 390 x 3 pounds each so × this and gives you 1170 cost sold for intotal

Then you have 260 ÷2 = 130 x 5 = 650

so you have 650+1170 = 1820 - 1100 cost to make =720 pounds

Graph this function using intercepts Solve 10x+9y=-90
Alex17521 [72]

Answer:

Step-by-step explanation:

So first, lets solve for the intercepts.

Let’s start by finding the x intercept.

Plug in 0 for y.

10x+9(0)=-90

10x=-90

X=-9, so your first point on your line will be (-9,0).

Now the y intercept.

Plug in 0 for x.

10(0)+9y=-90

9y=-90

Y=-10, so your second point on your line will be (0,-10).

Use those points to create your line.

2. Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral. Show your work
Nostrana [21]
On this picture is shown a quadrilateral inscribed in a circle and by the Inscribed Quadrilateral Theorem the angles on the opposite vertices are supplementary, or in other words are equals to 180 degrees. 

On this exercise it is asked to find the measure of angle B, First of all, you need to find the value of x. To so you have to select two opposite angles on this case angles A and C.

m<A+m<C=180      Substitute the given values for angles A and C
    x+2+x-2=180       Combine like terms
             2x=180       Divide by 2 in both sides to isolate x
               x=90

Now, that the value of x is known you can substitute it in the expression representing angle D, and then subtract that number from 180 to find the measure of angle B.

m<D=x-10             Substitute the value of x
m<D=90-10           Combine like terms
m<D=80

m<B=180-m<D       Substitute the value of angle D
m<B=180-80           Combine like terms 
m<B=100

The measure of angle B is 100 degrees, and the value of x is 90.
