Step-by-step explanation:

log8 64 = a

cut log and base^a

64 = 8^a

8^a = 64

or a = 2

Answer:

[tex]8^a = 64[/tex], which gives [tex]a=2[/tex].

Step-by-step explanation:

When you see [tex]\log_8(64)=a[/tex], think: [tex]a[/tex] is the number such that [tex]8^a = 64[/tex]. Mathematical intuition gives us that [tex]a=2[/tex] immediately, but we can also work this out more methodologically:

[tex]8^a = 64\\(2^3)^a = 2^6\\2^{3a} = 2^6\\3a = 6\\a = 2[/tex]

And this solution suffices.

Answer:

Sum = 900 degrees.

Step-by-step explanation:

Sum = (n-2)180

=(7-2)180

=(5)180

=900

Answer:

900 degrees

Step-by-step explanation:

The formula for calculating the sum of the interior angles of a regular polygon is : ( n - 2) × 180°. when n is number of sides.

Sum of angles = ( n-2) × 180

Sum of angles = (7-2) × 180

Sum of angles = 5 × 180

Sum of angles = 900 degrees

3x+20=100

Now you would need to move the constant to the right side and change within it’s sign

3x=100-20

Now you would subtract the numbers so for 100-20 would give you 80

So now you then do 3x=80

But if you want to divide the equation, divide it by both sides by 3

Which would give you x=80/3, x=26.6 or x=26 2/3

Answer:your answer is D.

Step-by-step explanation:

When dividing fractions you must flip the numerator and denominator so that would leave you with 6/1 divided by 3/4, solve this and then you have an improper fraction so after you multiply by 3 you must divide because of the improper fraction and you will divide by 4.

Answer:

7

Step-by-step explanation:

average of 7th grade - average of 8th grade = 7

average of 7th = (52+55+57+57+58+60+60+62+64+65)/10

= 590/10

= 59

average of 4th = 44+48+48+51+52+52+54+54+57+60

= 520/10

= 52

59 - 52 = 7

7 and there is more variability in the height of 7th grade girls

Step-by-step explanation:

4th grade

44+48+48+51+52+52+54+54+57+60

found the median which is 52 and 52 but you add them and divide them by 2 to get the median which is 104/2= 52

7th grade

52+55+57+57+58+60+60+62+64+65

median is 60 + 58=118/2= 59

59-52= 7

and

there is more variabilty in the hieght f 7th grade girls. because 4th grade has a lot of modes already while 7th grade has only like two so 7th grade will have more variability.

Answer:

Amount on 11% note = $106,666.67

Amount on 8% note = $43,333.33

Step-by-step explanation:

Let the amount for the ​short-term note at ​11% interest be x.

Thus, the amount for the ​short-term note at ​8% interest will be (150000 - x)

Now we are told that the total interest paid is $15,200.

Thus;

0.11x + 0.08(150000 - x) = 15200

0.11x + 12000 - 0.08x = 15200

Rearranging gives;

0.03x = 15200 - 12000

0.03x = 3200

x = 3200/0.03

x = $106666.67

Thus, amount for 8% note = $150000 - $106666.67 = $43,333.33

Answer:

x = 11

Step-by-step explanation:

sides of triangle measure: 'x', '4x-2' and '4x-2' since isosceles means both legs are equal

perimeter is the sum of all sides, so set up equation:

95 = 4x - 2 + 4x - 2 + x

95 = 8x - 4 + x

95 = 9x - 4

99 = 9x

x = 11

Answer:

The initial weight of the bar soap is 123g

Step-by-step explanation:

No options but the question can still be solved.

Given

[tex]y = -5.6x + 123[/tex]

Required

What does the y intercept mean

Start by calculating the y intercept (i.e. when x = 0)

The equation becomes

[tex]y = -5.6*0 + 123[/tex]

[tex]y = 0 + 123[/tex]

[tex]y = 123[/tex]

This means that the initial weight of the bar soap is 123g

The difference 0.2−0.05 is equal to 0.15.

To find the difference between 0.2 and 0.05.

The larger number  is 0.2.

The smaller number is 0.05.

When you subtract 0.05 from 0.2, you align the decimal points and subtract each digit accordingly:

[tex]0.2 - 0.05[/tex]

[tex]= 0.15[/tex]

So, the difference between 0.2 and 0.05 is 0.15.

Answer:

A cylinder 10 cm high with a circumference of 30 cm would have a greater volume

Step-by-step explanation:

Volume of a Cylinder

Given a cylinder of radius r and height h, the volume is calculated as:

[tex]V=\pi r^2h[/tex]

It's given a rectangular strip of aluminum 30 cm long and 10 cm wide. If we roll it to form a cylinder we can do it in two ways.

Rolling it across its length will make the cylinder have a height of h=10 cm and the circumference of the base equal to 30 cm.

The circumference of a circle of radius r is:

[tex]C=2\pi r[/tex]

Thus the radius is:

[tex]\displaystyle r=\frac{C}{2\pi}[/tex]

[tex]\displaystyle r=\frac{30}{2\pi}=\frac{15}{\pi}[/tex]

Thus the volume of the cylinder is:

[tex]V=\pi ( \frac{15}{\pi})^2*10[/tex]

[tex]V=\pi ( \frac{225}{\pi^2})*10[/tex]

[tex]V= \frac{2250}{\pi}[/tex]

If we rolled the strip across its width, then the height will be h=30 cm and the circumference C=10 cm, thus the radius is:

[tex]\displaystyle r=\frac{10}{2\pi}=\frac{5}{\pi}[/tex]

And the volume is:

[tex]V'=\pi ( \frac{5}{\pi})^2*30[/tex]

[tex]V'=\pi ( \frac{25}{\pi^2})*30[/tex]

[tex]V'= \frac{750}{\pi}[/tex]

Dividing V/V' = 3. The first volume it 3 times as much as the second volume.

A cylinder 10 cm high with a circumference of 30 cm would have a greater volume

Step-by-step explanation:

Figure A is 5 spaces down reflected off of figure B.

Answer:

Step-by-step explanation:

Suppose F represents the value that a room is unlocked.

Then, we can assume that the probability of unlocked homes is:

P(unlocked homes) = P(U)

P(unlocked homes) = 40%

P(unlocked homes) = 0.40

Also, let us represent the value of the locked room with G.

P(locked homes) = P(G)

P(locked homes) = (1 - 0.40)

P(locked homes) = 0.60

Let the probability of selecting a correct key be P(S)

It implies that for the agent to use 3 keys, we have a combination of [tex]^8C_3[/tex] possible ways for the set of keys.

Now; since only one will open the house, then:

P(select correct key) = P(S)

[tex]P(S) = \dfrac{ (^1_1) (^7_2) }{ ^8_3 }[/tex]

[tex]P(S) = \dfrac{21}{56}[/tex]

P(S) = 0.375

Finally, for the real estate agent to have access to specific homes supposing the agent select three master keys at random prior to the time he left his office, Then:

P(F ∪ (G∩S) = P(F) + P(G∩S)

P(F ∪ (G∩S) = P(F) + P(G) × P(S)

P(F ∪ (G∩S) = 0.40 + (0.60×0.375)

P(F ∪ (G∩S) = 0.40 + 0.225

P(F ∪ (G∩S) =0.625

Answer: 0.887

Step-by-step explanation:

Answer:

Pilot error = 347 / 1487 = 0.233 = 23.3%

Other human error = 83 / 1514 = 0.055 = 5.6%

Weather = 596 / 1487 = 0.401 = 40.1%

Mechanical problem = 374 / 1487 = 0.233 = 23.3%

Sabotage = 114 / 1487 = 0.077 = 7.7%

Step-by-step explanation:

Given the data :

Pilot error = 347

Other human error = 83

Weather = 596

Mechanical problem = 374

Sabotage = 114

Cummlative sum = (347 + 83 + 596 + 374 + 114) = 1487

Relative frequency :

Pilot error = 347 / 1487 = 0.233 = 23.3%

Other human error = 83 / 1514 = 0.055 = 5.6%

Weather = 596 / 1487 = 0.401 = 40.1%

Mechanical problem = 374 / 1487 = 0.233 = 23.3%

Sabotage = 114 / 1487 = 0.077 = 7.7%

Based on the relative frequency estimate, Weather is the most serious threat to aviation safety.
