given that log 8=0.931,log9=0.9542.fimd the value of log60
9514 1404 393
Answer:
log(60) = 1.7781
Step-by-step explanation:
60 = 3·2·10 = (√9)(∛8)(10)
log(60) = (1/2)log(9) +(1/3)log(8) +1 = 0.9542/2 +0.9031/3 +1
log(60) ≈ 1.7781 . . . . accurate in all digits shown
_____
It appears that the problem statement has a missing digit in the log of 8. It is actually about 0.9031, so that is the value we used above.

A supply company manufactures copy machines. The unit cost of C (the cost in dollars to make each copy machine) depends on the number of machines made. If x machines are made, then the unit cost is given by the function C(x)=0.4x^2-232x+38,207. How many machines must be made to minimize the unit cost? Do not round your answer.
Answer:
The unit cost C (the cost in dollars to make each copy machine) depends on the number of machines made. If x machines are made, then the unit cost is given by the function C (x) = 0.8x ^ 2 - 256x +25,939 .

The value of the equation is A = 2 2/7
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first number be P = 6 2/7
The value of P = 44/7
Let the second number be Q = 2 3/4
The value of Q = 11/4
A = ( 6 2/7 ) / ( 2 3/4 )
On simplifying the equation , we get
A = ( 44/7 ) / 11/4
A = ( 44/7 ) x ( 4/11 )
A = 16/7
Therefore , the value of A is 2 2/7
Hence , the equation is A = 2 2/7

In your own words, explain what treating your credit card like cash means.
Answer:
It means that you need to not use a lot of money on your credit card. When you have cash, you can only use the money that you have while on a credit card, you don't really have a limit to your use of money.
:)
Step-by-step explanation:
Treating your credit card like cash means always spending the money from a credit card carefully, as we do in cash. Because spending exceeding money can cause you in debt.
What are credit cards and cash?
A credit card is a card that is used to spend money that is paid afterward. These cards are issued by banks so that we can spend money when we want to.
It suggests you shouldn't put a lot of money on your credit card. When you have cash, you can only spend what you have, whereas, with a credit card, you have no restrictions on how much money you can spend.
Therefore, treating your credit card like currency entails always spending money from a credit card with caution, just as we do with cash. Because spending too much money can lead to debt.

We are designing gift bags of fruit, and a bag is supposed to contain 30 pieces of fruit. Find the number of bags of fruit that can be made out of apples, bananas, oranges, and pears, where, in each bag, the number of apples is even, the number of bananas is a multiple of 5, the number of oranges is at most 4, and the number of pears is 0 or 1.
a. What if the 30 were replaced by n?
b. Is there a formula for the number of bags with n pieces of fruit that obey these rules?
Step-by-step explanation:
For each type of fruit, the corresponding generating function will be:
For apples the generating function will be:
For banana the generating function will be:
For orange the generating function will be:
[tex]\sum_{e 3=0}^{\infty} x^{e^{3}} &=1+x+x^{2}+x^{3}+x^{4}+\ldots \ldots \\

There is a line whose slope is 10 and whose y -intercept is 6. What is its equation in slope -intercept form?
will give brainiest! <3
Answer:
The equation is y = 10x + 6.
Step-by-step explanation:
In a slope-form equation, y = mx + b, m represents gradient and b is y-intercept. Given that slope is 10 and y-intercept is 6. So the equation will be y = 10x + 6.
Answer:
y = 10x + 6
Step-by-step explanation:
slope-intercept (a.k.a. y-intercept) form is y = mx + b
m represents the slope and b represents the y intercept, so when writing in slope-intercept form, just replace m and b with that information.

Color of socks white black blue brown
Number of socks 3 9 5 2
The ratio of white socks to brown socks is
Answer:
White Socks: 1/4 of the whole
Black Socks: 3/4 of the whole
Step-by-step explanation:
white socks to black socks:
3:9
White Socks: 1/4 of the whole
Black Socks: 3/4 of the whole
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 3 + 9 = 12
White Socks: = 3 and Black Socks: = 9 are numerators for each fraction.
The fractions are then:
3/12 and 9/12
Meaning:
White Socks are 3/12 of the whole
Black Socks are 9/12 of the whole
Reducing the fractions, it is also true that:
White Socks = 1/4 of the whole
Black Socks = 3/4 of the whole

The price of a television is marked down for a weekend sale. After the sale is over, the price of the television is back to its original price. Are the percent of decrease and the percent of increase the same? Explain your thinking
9514 1404 393
Answer:
No. The bases for computing percentages are different.
Step-by-step explanation:
Suppose the original price is $100 and it is marked down 20%. Then the amount of markdown is 0.20×$100 = $20. The marked-down price is then $100 -20 = $80.
After the sale, the price increase of $20 is computed using the base price of $80:
increase % = $20/$80 × 100% = 25%
The percentage decrease and increase are different because they are computed using different numbers as the reference.
__
Additional comment
The closer to zero the percentages are, the closer they are to being the same. A 1% markdown will equate to a 1.010101...% markup, for example.

17. A hemisphere of lead of radius 7 cm is cast into a right circular cone of height 49 cm. Find
the radius of the base of the cone
Answer:
[tex]r = 3.74cm[/tex]
Step-by-step explanation:
Given
Hemisphere
[tex]Radius = 7cm[/tex]
Cone
[tex]Height = 49m[/tex]
Required
Determine the radius of the cone
First, we calculate the volume (V1) of the hemisphere.
[tex]V_1 = \frac{2}{3}\pi r^3[/tex]
Substitute 7 for r
[tex]V_1 = \frac{2}{3}\pi * 7^3[/tex]
[tex]V_1 = \frac{2}{3}\pi * 343[/tex]
[tex]V_1 = \frac{686}{3}\pi[/tex]
Volume (V2) of a cone is:
[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]
Because the lead is cast into a cone, then they have the same volume.
So, we have:
[tex]\frac{686}{3}\pi = \frac{1}{3}\pi r^2h[/tex]
[tex]686 = r^2h[/tex]
Substitute 49 for h
[tex]686 = r^2 * 49[/tex]
Divide both sides by 49
[tex]r^2 = \frac{686}{49}[/tex]
[tex]r^2 = 14[/tex]
[tex]r = \sqrt{14[/tex]
[tex]r = 3.74cm[/tex]
Hence, the radius of the cone is 3.74cm

From the table, you'ld realise that it is in a sequence of (12), that is 1×12=12, 2×12=24, therefore, the number of passengers that can be transported in 5 vans are 5×12= 60 passengers.
The projected value of an investment is modeled by the exponential function V(t) = 30,000(1.125) where V(t) is the total value
after t years. What does 1.125 represent in the function?
The growth factor of the investment
The initial value of the investment
The projected value of the investment
D)
The value of the investment after t years:
Exponential function is given by [tex]A(t)=A_0(1+r)^t[/tex].
Option (1) will be the correct option.
An exponential function given in the form of [tex]A(t)=A_0(1+r)^t[/tex]represents the growth/decay function.
Here, [tex]A(t)=[/tex] Final value
[tex]A_0=[/tex] Initial value
[tex]t=[/tex] Duration or time
[tex]r=[/tex] Rate of growth or decay
(1 + r) = Growth factor
By comparing this function with the exponential function given for the investment,
[tex]V(t)=30000(1.125)^t[/tex]
[tex](1+r)=(1+0.125)[/tex]
Therefore, 1.125 is the growth factor of the investment.
