9 t-shirts and a hat costs £93.00 4 t-shirts and a hat costs £43.00.
How much does a t-shirt cost?
How much does a hat cost?

Tell the the answer for the T-shirt and hat

is is 10 for shirt and 3 for hat

Step-by-step explanation:

Let a hat be x and a t shirt be y.

9y + x = 93 (1)

4y + x. = 43(2)

Using the elimination method

Multiply eqn (2) by -1 and eqn by +1

9y + x =. 93(3)

-4y - x.= -43(4)

Add both equations

5y =. 50(5)

y. =. 50 ÷5 = 10

y. =. 10

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
