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.

A robotic machine fills containers with an acid solution at the rate of 50 + 5 t milliliters (mL) per second, where t is in seco
Alika [10]

Answer:

12,000

Step-by-step explanation:

The machine fills the containers at a rate of 50+5t milliliters (mL) per second.

Therefore, the rate of change of the number of containers, N is:

\dfrac{dN}{dt}=50+5t, 0\leq t\leq 60

dN=(50+5t)dt\\$Taking integrals of both sides\\\int dN=\int (50+5t)dt\\N(t)=50t+\frac{5t^2}{2}+C $(C a constant of integration)\\\\When t=0, , No containers are filled, therefore:$ N(t)=0\\0=50(0)+\frac{5(0)^2}{2}+C\\C=0\\$Therefore, N(t)=50t+2.5t^2

When t=60 seconds

N(60)=50(60)+2.5(60)^2\\N(60)=12000$ mL

Therefore, 12,000 milliliters of acid solution are put into a container in 60 seconds.

Roots of x^2+8x+9 by finding in quadratic formula
gladu [14]
The quadratic formula is -b + or - the square root of b squared - 4 times the a value and c value over 2a. So the roots would be -1.354249 and -6.645751. I believe these are the roots.
