Answer:
B. 6.7
Step-by-step explanation:
The triangles are similar, so corresponding sides have the same ratio.
hypotenuse/short side = m/3 = (12+3)/m
m² = 3(15) = 45
m = √45
m ≈ 6.7

What is the value of log↓3 81? 2, 3, 4 or 5?
Answer:The value of log base 3 log base 2 log base √3 81 is -a)1 b) 2 c)3 d) 0
Answer:
4
Step-by-step explanation:
Define [tex]\log_a b=c\implies a^c=b[/tex].
Let
[tex]\log_3 81=x[/tex].
Using our definition [tex]\log_a b=c\implies a^c=b[/tex], we have:
[tex]3^x=81[/tex]
Solving for [tex]x[/tex]:
[tex]x=\boxed{4}\text{ from simply knowing that }3^4=81[/tex]
Or
Algebraically solve step-by-step by taking the log of both sides:
[tex]\log 3^x=\log 81[/tex]
Using log property [tex]\log a^b=b\log a[/tex], rewrite:
[tex]x\log 3=\log81[/tex]
Divide both sides by log(3):
[tex]x=\frac{\log 81}{\log 3}=\boxed{4}[/tex]

A taxicab moves five blocks due north, five blocks due east, and another three blocks due north. Assume all blocks are of equal size. How far is the taxi from its starting point
Answer:
9.43
Step-by-step explanation:
Given
See attachment for illustration
Required
Distance AE
The actual path taken by the taxicab are in bold lines.
To calculate the distance AE, we simply consider the triangle AOE where
[tex]AE^2 = OE^2 + AO^2[/tex]
[tex]AE^2 = 5^2 + (5+3)^2[/tex]
[tex]AE^2 = 5^2 + 8^2[/tex]
[tex]AE^2 = 25 + 64[/tex]
[tex]AE^2 = 89[/tex]
Take square roots
[tex]AE = \sqrt{89[/tex]
[tex]AE = 9.43[/tex]
The radius of a sphere is increasing at a rate of 5 mm/s. How fast is the volume increasing when the diameter is 40mm? Note: The volume of a sphere of radius, r, is given by V = (4/3)pi r^3
Answer:
The volume is increasing at a rate of 25,133 mm/s.
Step-by-step explanation:
Diameter is 40mm
Radius is half the diameter, so [tex]r = \frac{40}{2} = 20[/tex]
How fast is the volume increasing when the diameter is 40mm?
We have to apply implicit differentiation, of V and r in function of t. So
[tex]V = \frac{4}{3} \pi r^3[/tex]
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
The radius of a sphere is increasing at a rate of 5 mm/s.
This means that [tex]\frac{dr}{dt} = 5[/tex]
Then
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
[tex]\frac{dV}{dt} = 4\pi (20)^2(5)[/tex]
[tex]\frac{dV}{dt} = 25133[/tex]
The volume is increasing at a rate of 25,133 mm/s.

An American roulette wheel contains 38 slots. Eighteen of the slots are colored red and eighteen are
colored black. The remaining two slots are colored green. A ball is spun on the wheel and comes to
rest in one of the 38 slots. If you bet $1 on the color red and win, the house pays you $1 (even
money).
What is the expected value of betting on red?
$1
0-$1
-$5.30
-$0.053
Answer:
- $0.053
Step-by-step explanation:
Bet fee = $1
Probability of red = 18 / 38
Probability of black = 18/38
Probability of green = 2 / 38
x : ____1 _____ - 1 _____ - 1
P(x) : __ 18/38___ 18/38____ 2/38
Mean or expected value, E(X) = Σx*p(x) = (18/38) * * (-18/38) * (-2/38)
E(X) = - 0.052631
E(X) = - $0.053

What is the difference in unit price between a 5 gallon bucket of paint for $97.45 and a 1 gallon bucket of paint for $21.95?
Answer: $2.46
Step-by-step explanation:
First, let's find the unit price for both buckets!
A 1 gallon bucket of paint is $21.95. But how much will a 1 gallon bucket of paint cost if it had origianlly been 97.45 for 5 gallons of paint?
We need to divide 97.45 by 5, and the answer will be the unit price.
97.45 ÷ 5 = 19.49.
A 1 gallon bucket of paint that was originally priced as $97.45 for 5 gallons of paint si now $19.49 per bucket.
But we're not done! We still need to find the difference in unit prince between a 5 gallon bucket of paint for $97.45 and a 1 gallon bucket of paint for $21.95.
21.95 - 19.49 = 2.46.
Therefore, the difference in unit price between a 5 gallon bucket of paint for $97.45 and a 1 gallon bucket of paint for $21.95 is $2.46.

If you place a 24-foot ladder against the top of a 20-foot building, how many feet will the bottom of the ladder be from the bottom of the building? Round to the nearest tenth of a foot.

Pythagoras theorem states that for a right angle triangle the measure of the square of the hypotenuse side is equal to the sum of the square of the other two sides.The ladder has to be kept at 13.3( round to the nearest tenth) feet away from the bottom of the wall.
Given information-
The length of the ladder is 24 foot.
The height of the wall is 20 foot.
Suppose the ladder has to kept at x feet away from the bottom of the wall
Here a right angle is formed in which the ladder is hypotenuse side shown in the diagram attached below.
Pythagoras theoremPythagoras theorem states that for a right angle triangle the measure of the square of the hypotenuse side is equal to the sum of the square of the other two sides.
As the ladder has to be kept at x feet away from the bottom of the wall. Thus,
[tex]24^2=20^2+x^2\\ 576=400+x^2[/tex]
Solve for the x,
[tex]x=\sqrt{576-400}\\ x=\sqrt{176}\\ x=13.266[/tex]
hence the ladder ladder has to be kept at 13.3( round to the nearest tenth) feet away from the bottom of the wall.

C = 109.3°
a = 5.6 km
b = 10.7 km
Answer:
c=13.6km, B=47.9⁰, A=22.8⁰,
Using the cosine rule, the missing parts of the triangle are:
c = 13.6 km; B = 47.9°; C = 22.8°
What is the Cosine Rule?Cosine rule is given as, c² = a² + b² ﹣ 2ab(cosC)
Given the following:
C = 109.3°a = 5.6 kmb = 10.7 kmFind c using the cosine rule:
c² = 5.6² + 10.7² ﹣ 2(5.6)(10.7)(cos 109.3)
c² = 185.5
c = √185.5
c = 13.6 km.
Use the cosine rule to find A:
5.6² = 10.7² + 13.6² ﹣ 2(10.7)(13.6)(cosA)
31.36 = 299.45 ﹣ 291.04(cosA)
31.36 - 299.45 = ﹣ 291.04(cosA)
-268.09 = ﹣ 291.04(cosA)
0.9211 = (cosA)
C = cos^(-1)(0.9211)
C = 22.8°
Find B:
B = 180 - 22.8 - 109.3
B = 47.9°

The function h (x) = four-thirds x minus 1 represents the composite h(x) = f(g(x)). If f(x) = 2x – 1, what is g(x)?
g (x) = two-thirds x
g (x) = two-thirds x minus 1
g (x) = 2 and one-third x
g (x) = 2 and one-third x minus 1
The g(x) is equal to (2/3)x.To find g(x) in the composite function h(x) = f(g(x)), we need to substitute f(x) = 2x - 1 into the equation and solve for g(x
Given that h(x) = (4/3)x - 1 and f(x) = 2x - 1, we can set up the composite unction:
h(x) = f(g(x))
Substituting f(x) into the equation:
(4/3)x - 1 = 2(g(x)) - 1
Simplifying the equation:
(4/3)x - 1 = 2g(x) - 1
We can now solve for g(x):
2g(x) = (4/3)x
Dividing both sides by 2:
g(x) = (2/3)x

Given that r= 2p2/q-3 ; rearrange the formula to make q the subject of the formula.
Step-by-step explanation:
The given expression is:
[tex]r=\dfrac{2p^2}{q-3}[/tex]
We need to solve it to make q the subject of the formula.
Cross multiplying both sides,
[tex]rq-3r=2p^2[/tex]
Adding 3r to both sides,
[tex]rq-3r+3r=2p^2+3r\\\\rq=2p^2+3r[/tex]
Now, dividing both sides by r,
[tex]q=\dfrac{2p^2+3r}{r}[/tex]

If the price of 12 shirts is rupees 3600 3/5 and of 6 pants is rupees 3000 1/5 . Find the price of 4 shirts and 4 pants
Given:
Price of 12 shirts = Rs. [tex]3600\dfrac{3}{5}[/tex]
Price of 6 pants = Rs. [tex]3000\dfrac{1}{5}[/tex]
To find:
The price of 4 shirts and 4 pants.
Solution:
It is given that,
Price of 12 shirts = Rs. [tex]3600\dfrac{3}{5}[/tex]
Price of 1 shirt = Rs. [tex]\dfrac{1}{12}\times 3600\dfrac{3}{5}[/tex]
Price of 4 shirts = Rs. [tex]\dfrac{4}{12}\times 3600\dfrac{3}{5}[/tex]
= Rs. [tex]\dfrac{1}{3}\times \dfrac{18003}{5}[/tex]
= Rs. [tex]\dfrac{18003}{15}[/tex]
Price of 6 pants = Rs. [tex]3000\dfrac{1}{5}[/tex]
Price of 1 pant = Rs. [tex]\dfrac{1}{6}\times 3000\dfrac{1}{5}[/tex]
Price of 4 pants = Rs. [tex]\dfrac{4}{6}\times 3000\dfrac{1}{5}[/tex]
= Rs. [tex]\dfrac{2}{3}\times \dfrac{15001}{5}[/tex]
= Rs. [tex]\dfrac{30002}{15}[/tex]
Now, the price of 4 shirts and 4 pants is:
[tex]\text{Required price}=\dfrac{18003}{15}+\dfrac{30002}{15}[/tex]
[tex]\text{Required price}=\dfrac{48005}{15}[/tex]
[tex]\text{Required price}=\dfrac{9601}{3}[/tex]
[tex]\text{Required price}=3200\dfrac{1}{3}[/tex]
Therefore, the price of 4 shirts and 4 pants is Rs. [tex]3200\dfrac{1}{3}[/tex].
