Step-by-step explanation:

25x = 300 Divide by 25

25x/25=300/25 Do the division

The pie chart shows information about voters in an election. 3360

Lesechka [4]

Answer:

4838 total number of voters

Step-by-step explanation:

In a whole circle there 360°, in a straight line theres 180°.

180-110=70 first to break it down to find the degrees of women.

180+70=250° for women.

250°=3360

we need to find 110° of men

25°=336

times 4

100°=1344

divide by 10

10°=134.4 round down 134

1344+134=1478

3360+1478=4838

How high is the building (ie. from what height was the potato launched) if h=-2(t-3)2+32

Llana [10]

Answer:

Step-by-step explanation:

To find the height from which the potato was launched, you need to set the time to 0 (since that is at the beginning). Plugging this into the equation, you get:

$h=-2(0-3)^2+32$

h=-2(9)+32

h=32-18

h=14

Hope this helps!
