Answer:
445.2 square cm
Step-by-step explanation:
The surface area consists of area of two bases and area of three leteral faces. Each lateral face is a rectangle with length of 23 cm and width of 6 cm.
The area of rectangle is
So,
The area of base is given as
Thus, the surface area is
Hey there! I'm happy to help!
<u>In a 30-60-90 triangle, the shorter leg is always 1/2 of the hypotenuse.</u> This can be proven using many different methods and there a lot of interesting videos out there about it. This is useful in geometry, trigonometry, and more.
So, if we know that the shortest leg is 12, we can make the following equation. We will have h represent the hypotenuse.
1/2h=12
Now, we simply divide both sides by 1/2 (which is the same as multiplying both sides by two.
h=24
Therefore, the hypotenuse is C) 24.
I hope that this helps! Have a wonderful day!

Answer:
55.4
Step-by-step explanation:
SOH
sin (θ°) = opposite / hypotenuse
sin (28) = 26/x
Solve for x (hypotenuse).
x = 26/(sin (28))
x = 55.38141617...
Nearest tenth.
x ≈ 55.4
Given:
lemon juice = 60% in the bottle
water = 1 liter.
Since lemon juice is 60% and the rest is water. Water is 40% of the bottle.
1 liter of water is equivalent to 40% of the bottle.
1/40% = 2.50 liters amount of total liquid in the water.
2.50 x 60% = 1.5 liters of lemon juice.
0.6x + 0.4x = 2.5
