Answer:
h =12
Step-by-step explanation:
[tex]In\: \triangle ABC, \: \angle ABC = 90\degree \: \&\:\\ BD\perp AC[/tex]
Therefore, by geometric mean property:
[tex]BD = \sqrt {AD\times CD} \\
h = \sqrt {(AC-CD) \times CD} \\
h = \sqrt {(25-16) \times 16} \\
h = \sqrt {9 \times 16} \\
h = \sqrt {144} \\
\huge \red {\boxed {h = 12}} \\

Answer:
Your answer is D
Step-by-step explanation:
f(2) This means that x is 2, so you can plug in 2 for "x" in the equation
f(x) = 3x - 12
f(2) = 3(2) - 12
f(2) = 6 - 12
f(2) = -6

Solve the formula V = 1/3b^2 h for b.

Answer:
[tex]b=\sqrt{\frac{3V}{h}}[/tex]
Step-by-step explanation:
To solve a formula for one of its variables do that
Underline the variableSeparate it on one side and the other terms on the other sideMake its coefficient equals 1Let us use these steps to solve our question
∵ V = [tex]\frac{1}{3}[/tex] b²h
→ Underline b
∴ V = [tex]\frac{1}{3}[/tex] b²h
→ Multiply both sides by 3 to cancel the denominator on the right side
∴ 3V = b²h
→ Divide both sides by h to move it to the other side
∴ [tex]\frac{3V}{h}=b^{2}[/tex]
→ To find b take √ for both sides
∴ [tex]\sqrt{\frac{3V}{h}}=\sqrt{b^{2} }[/tex]
→ The square root will cancel the power 2 of b
∴ [tex]\sqrt{\frac{3V}{h}}=b[/tex]
→ Switch the two sides
∴ [tex]b=\sqrt{\frac{3V}{h}}[/tex]

A. 57.76 cm²
B. 86.64 cm²
C. 144.4 cm²
D. 361 cm²
Answers
Answer:
86.64 cm
Step-by-step explanation:
i have no idea i guessed on got it right on the quiz
The surface area of the red cloth of 60% paperweight is 86.64 square cm. Then the correct option is B.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The surface area of the paperweight will be given as
[tex]\rm Surface \ area = 2\times (5*3 + 6*3) + 5*6 + 2 \times \dfrac{1}{2} * 5 * 2 + 2 \times (3.2 + 6)\\\\Surface \ area = 2 \times (33) + 30 + 2 \times 5 + 2\times 19.2\\\\Surface \ area = 66 + 30 + 10 + 38.4\\\\Surface \ area = 144.4[/tex]
This figure represents a small paperweight.
The plan is to cover 60% of the total surface area, including the bottom face, of the paperweight with red cloth.
The surface area of the red cloth will be
Surface area of red cloth = 0.6 × 144.4
Surface area of red cloth = 86.64 cm²
