Answer:

D. 0.89

Step-by-step explanation:

Use the change of base rule:

\log_b a = \dfrac{\log_x a}{\log_x b}

\log_9 7 =

= \dfrac{\log_{10} 7}{\log_{10} 9}

= \dfrac{0.8451}{0.9542}

= 0.8856

Answer: D. 0.89

What is the volume of the composite figure? Explain your work. A complete answer should include how you broke up the figure, whi
Sphinxa [80]

Answer:

15,000\:\mathrm{mm^3}

Step-by-step explanation:

The composite figure consists of a square prism and a trapezoidal prism. By adding the volume of each, we obtain the volume of the composite figure.

The volume of the square prism is given by V=s^2\cdot h, where s is the base length and h is the height. Substituting given values, we have: V=14^2\cdot 30=196\cdot 30=5,880\:\mathrm{mm^3}

The volume of a trapezoidal prism is given by V=\frac{b_1+b_2}{2}\cdot l\cdot h, where b_1 and b_2 are bases of the trapezoid, l is the length of the height of the trapezoid and h is the height. This may look very confusing, but to break it down, we're finding the area of the trapezoid (base) and multiplying it by the height. The area of a trapezoid is given by the average of the bases (\frac{b_1+b_2}{2}) multiplied by the trapezoid's height (l).

Substituting given values, we get:

V=\frac{14+24}{2}\cdot (30-14)\cdot 30,\\V=19\cdot 16\cdot 30=9,120\:\mathrm{mm^3}}

Therefore, the total volume of the composite figure is 5,880+9,120=\boxed{15,000\:\mathrm{mm^3}} (ah, perfect)

Alternatively, we can break the figure into a larger square prism and a triangular prism to verify the same answer:

V=30^2\cdot 14+\frac{1}{2}\cdot10\cdot 16\cdot 30=\boxed{15,000\:\mathrm{mm^3}}\checkmark

If the probability of a win is 0.02, and the probability of a draw is 0.8, what is the probability of a loss?
atroni [7]
A probability is a number between zero and one. 

There are 3 options win, lose or draw. 
This means that (win + loss + draw = 1)

From the information given you know:
Win = 0.02
Draw = 0.8 

So: 0.02 + loss + 0.8 = 1 
Therefor loss = 1 - 0.8 - 0.02 
loss = 0.18 
final answer ^ 

Hope this helps, let me know if you don't get any of it!

Selection D) is appropriate.

The triangles are congruent by SSA, given the angle is a right angle, not ASA or AA. YX is not congruent to UW, so C) is incorrect.
