Answer:

1.) 36m        2.) 275cm

3.) 52m       4.)

Step-by-step explanation:

1.) First, I would multiply the triangles. The area for triangles is A=BxH/2.

So you would do 4mx3m=12m

12m/2= 6m but you're not done, you still have the rectangle. The area is A=LXW for the rectangle. So you would do 5m x 6m=30m. Finally, add.      30m + 6m= 36m

2.) Same thing as number one, but different numbers.

Triangle: 8cm x 10cm= 80cm

80cm/2= 40cm

Rectangle: 13cm x 15cm= 195cm

80cm + 195cm= 275cm

3.) Same as the last two except for it looks different and different numbers.

ignore the 5 to the left of the triangle.

3m x 8m= 24m

24m/2= 12m

5m x 9m= 40m

40m+12m= 52m

4.) I want you to try it first, then if not come back and ask. Hope it helps.

I asked more than 10 times Still no steps to a solution
Alisiya [41]

Answer:

C 200

Step-by-step explanation:

It does not appear to be LINEAR so

Start with :

pulse rate = y = 73e^kx  

sub in x = .7      when y = 155

155 = 73 e^(.7 * k)

ln ( 155/73)  =  .7k

.75296567  = .7k

     k = 1.07567

for x = 0.9 :

pulse rate  =  y = 73 e^(1.07567 * .9)  = ~ 192      so I expect answer is 200

if a rectangle has an area of 30 square meters and a perimeter of 34 meters . what is the dimensions of the rectangle?
timama [110]
P=2(L+W)  and P=34 so

2(L+W)=34

L+W=17 so we can say

L=17-W

A=LW using L from above

A=(17-W)W

A=17W-W^2 and A=30 so

30=17W-W^2

W^2-17W+30=0

W^2-2W-15W+30=0

W(W-2)-15(W-2)=0

(W-15)(W-2)=0

So the dimensions of the rectangle are 15 meters by 2 meters.
