The area of trapezium shaped field is 480 square meter, the distance between two parallel sides is 15m and one of the parallel side is 20m. Find the other parallel side

Answers

Answer: 44 m

Step-by-step explanation:

Given

The area of the trapezium is [tex]A=480\ m^2[/tex]

Distance between parallel sides [tex]h=15\ m[/tex]

One of the parallel sides is [tex]20\ m[/tex]

Suppose the other parallel side is [tex]x[/tex]

The area of the trapezium is

[tex]A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h[/tex]

Put values

[tex]\Rightarrow 480=\dfrac{1}{2}\times [20+x]\times 15\\\\\Rightarrow 480\times 2=300+15x\\\Rightarrow 960-300=15x\\\Rightarrow x=44\ m[/tex]

A batter hits a baseball 4 feet above the ground with an upward velocity of 59 feet per second. The function h(t) = -16t^2 + 49t + 4 gives the height h (in feet) of the baseball after t seconds. How long is the ball in the air if a player on the other team catches the ball 7 feet above the ground?

Answers

Answer:

3 seconds

Step-by-step explanation:

when h=7 ft

-16t²+49t+4=7

-16t²+49t-3=0

16t²-49t+3=0

16t^2-48t-t+3=0

16t(t-3)-1(t-3)=0

(t-3)(16t-1)=0

t=3,t=1/16

t=1/16 seconds is the time when it just started.

so reqd.  time=3 seconds.

Step-by-step explanation:

please make me a happy with brainleist answer

The value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory option (A) is correct.

What is LIFO?

Last in, first-out (LIFO) is an inventory valuation approach based on the principle that the first asset sold is the most recent asset received.

We have data shown in the table:

Total number of T-shirts = 200+300+400+300 = 1200

As there are only 400 T-shirts left it means,

So (1200-400)800 T-shirts sold out according to LIFO last month T-shirt sold out.

200 T-shirts left in the June stock

Out of 300, there are 200 T-shirts left in the month of July.

Cost for 200 T-shirts = 200×8 = $1600

Cost for 200 T-shirts = 200×10 = $2000

Total cost = 1600+2000

= $3600

Thus, the value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory.
