Can someone help me
Deffense [45]

Answer:

w = 10 cm

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = \frac{1}{2} base × height

here base = 6 and height = 8, thus

A = 0.5 × 6 × 8 = 3 × 8 = 24 cm²

The area of the rectangle = 5 × 24 = 120 cm²

area of rectangle = lw ( l is length, w is width )

Here l = 12, thus

120 = 12w ( divide both sides by 12 )

w = 10 cm

Draw and label all three side lengths and angle measures of a right triangle that has a 40° angle and a hypotenuse 10 cm long.
Elodia [21]

Answer:

Right Triangles and the Pythagorean Theorem

1.The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.

2.The side opposite the right angle is called the hypotenuse (side c in the figure).

The pH level of tomato juice is 4.2. What is the hydrogen-ion concentration [H+]| for tomato juice?
garri49 [273]

Given:

pH = 4.2 of tomato

Required:

hydrogen-ion concentration [H+]| for tomato juice

Solution:

The formula for the pH relating hydrogen ion concentration is pH = -log[H+] where H+ is the hydrogen ion concentration. so, substitute the value of pH

pH = -log[H+]

4 = - log[H+]

-4 = log[H+]

10^-4 = [H+]

[H+] = 1x10^-4M
