How much is a 40% discount off of $74.99

Mathematics
1 answer:
pychu [463]3 years ago
7 0

Answer:

\frac{40}{100}  \times  \frac{7499}{100}

\frac{2}{5}  \times  \frac{7499}{100}

\frac{1}{5}  \times  \frac{7499}{50}

\frac{7499}{250}

7499/250= 29.996

74.99-29.996= $44.994

Identify the solution set of 3 In 4 = 2 In x.<br> -{6}<br> -{-8,8}<br> -(8)
o-na [289]

Option C: The solution set is \{8\}

Explanation:

The expression is 3 \ln 4=2 \ln x

Now, let us find the solution set.

Switch sides, we get,

2 \ln x=3 \ln 4

Dividing by 2 on both sides, we have,

\ln x=\frac{3 \ln 4}{2}

Thus,  \ln 4=\ln 2^2=2\ln 2

Hence, the above expression becomes,

\ln x=\frac{3 \cdot 2 \ln (2)}{2}

Simplifying, we get,

\ln x=3 \ln 2

Applying the log rule, we get,

$$\ln x$=\ln \left(2^{3}\right)$

Simplifying, we have,

$$\ln x$=\ln \left8\right$

Applying the log rule, we have,

x=8

Thus, the solution set is \{8\}

Hence, Option C is the correct answer.

If AB = 9, RS = 3, and SC = 5, find BC.<br> A) 5<br> B) 10<br> C) 13.5<br> D) 15
Ronch [10]

Answer:

D

Step-by-step explanation:

Δ ABC and Δ RSC are similar triangles, thus the ratio of corresponding sides are equal, that is

\frac{BC}{SC} = \frac{AB}{RS}, substitute values

\frac{BC}{5} = \frac{9}{3} = 3 ( multiply both sides by 5 )

BC = 5 × 3 = 15 → D
