Step-by-step explanation:
A warehouse worker moved 108 pallets in 4.5 hours. In minutes, what is the rate to move one pallet? The worker will be off the clock in 2 hours. How many pallets can he move before quitting time?
Number of pallets moved in 4.5 hours = 108
converting 4.5 hours in minutes we get,
4*60 + 0.5*60 = 240+30 = 270 minutes
So, 108 pallets were moved in = 270 minutes
1 pallet was moved in = [tex]\frac{270}{108}=2.5[/tex] minutes
As the tie will get over in 2 hours or 2*60 = 120 minutes, the number of pallets that can be moved will be = [tex]\frac{120}{2.5}= 48[/tex] pallets.
Hence, 48 pallets can be moved before quitting time.
Answer:
The answer is 2.5 minutes; 48 pallets
Step-by-step explanation:
Number of pallets worker moved in a warehouse = 108
Number of hours it takes to do so = 4.5
Rate at which they require to move one pallet is given by
Number of pallets worker moved in a warehouse = 108
Number of hours it takes to do so = 4.5
Rate at which they require to move one pallet is given by
4.5/108 x 60 minutes = 2.5 minutes
Now, if the worker will be off the clock in 2 hours ,
So, number of pallets he can move before quitting time is given by
In 4.5 hours, number of pallets they moved = 108
In 1 hour, number of pallets they moved = 108/4.5 = 24
In 2 hours, number of pallets they moved = 24 x 2 = 48

What is the equation of a line that is parallel to y=47x−3 and passes through (14, 4) ?
PARALLEL slopes always have the same slope no matter what because they are parallel
Answer:
[tex]y=47x-654[/tex]
Step-by-step explanation:
To find the line parallel to the given linear equation, we have to use the same slope, because the condition of parallelism is that they must have the same slope.
So, the slope of the given line is [tex]m=47[/tex], because it's expressed in slope-intercept form, where the coefficient of the variable x is the slope.
Now, we know that they new parallel lines must have a slope equal to 47, and must pass through (14,4). Using this data, we apply the point-slope formula to find the equation of the new line:
[tex]y-y_{1}=m(x-x_{1})\\y-4=47(x-14)\\y=47x-658+4\\y=47x-654[/tex]
The image attached shows the parallelism.
Therefore, the answer is [tex]y=47x-654[/tex]

Answer:
Step-by-step explanation:
4×+3Y-15-3y+×
The equivalent expressions to 5x-15 are 5(x-3), 4x+3y-15-3y+x, and -20-3x+5+8x. These simplify to 5x-15 when combining like terms and distributing, matching the original expression.
The student is asking which expressions are equivalent to 5x-15. To find the equivalent expressions, we need to check each option to see if they simplify to the same form.
5(x+15) is not equivalent because when you distribute the 5, you get 5x + 75, which is not the same as 5x - 15.5(x-3) is equivalent because when you distribute the 5, you get 5x - 15, which matches the original expression exactly.4x+3y-15-3y+x is equivalent because when you combine like terms (4x + x and 3y - 3y), you get 5x - 15.-7y-6x-8y+x is not equivalent because even if you combine like terms, the x terms do not add up to 5x, nor do the constants add up to -15.-20-3x+5+8x is equivalent because when you combine like terms (-3x + 8x), you get 5x, and when combining constants (-20 + 5), you get -15; hence, it simplifies to 5x - 15.Therefore, the expressions 5(x-3), 4x+3y-15-3y+x, and -20-3x+5+8x are equivalent to 5x - 15.

All real numbers greater than or equal to -6 and less than or equal to 6
The range is the interval [tex][-2,2][/tex]
All real numbers greater than or equal to -2 and less than or equal to 2
The graph's domain spans from -6 to 6, and the range extends from -2 to 2. In summary, the domain is [-6, 6], and the range is [-2, 2].
In the given graph, the domain represents all possible input values, and it spans from -6 to 6, inclusive. This is because the graph includes every real number greater than or equal to -6 and less than or equal to 6 along the horizontal axis.
The range, on the other hand, corresponds to the output values of the function and extends from -2 to 2, inclusive. This is derived from the observation that the graph encompasses all real numbers greater than or equal to -2 and less than or equal to 2 along the vertical axis.
The domain is [-6, 6], indicating all real numbers between -6 and 6, and the range is [-2, 2], signifying all real numbers between -2 and 2. The graph visually illustrates these intervals as the inclusive bounds for both domain and range.

What is the sum of the series 3,---5,-13..........-229
ANSWER
[tex]S_{30}= - 3390[/tex]
EXPLANATION
The given sequence is
3,-5,-13,.....-229.
The first term of this sequence is
a_1=3
There is a common difference of
[tex]d = - 5 - 3 = - 8[/tex]
The last term of this sequence is -229.
The nth term of this sequence is given by:
[tex]a_n=a_1+d(n-1)[/tex]
We use the last term to determine the number of terms in the sequence.
[tex] - 229 = 3 + - 8(n - 1)[/tex]
[tex]- 229 - 3= - 8(n - 1)[/tex]
[tex]- 232= - 8(n - 1)[/tex]
Divide through by -8;
[tex]29= (n - 1)[/tex]
[tex]n = 30[/tex]
Hence there are thirty terms in the sequence.
The sum of the first n terms is given by:
[tex]S_n= \frac{n}{2} ( a_{1} + l)[/tex]
The sum of the first 30 terms is given by:
[tex]S_{30}= \frac{30}{2} ( 3 + - 229)[/tex]
[tex]S_{30}=15( - 226)[/tex]
[tex]S_{30}= - 3390[/tex]

Myra invested $10,000 in an account earning a nominal 8% per year compounded continuously. How much was in the account at the end of one year? Round the answer to nearest dollar.
Answer:
[tex]\$10,833[/tex]
Step-by-step explanation:
we know that
The formula to calculate continuously compounded interest is equal to
[tex]A=P(e)^{rt}[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
e is the mathematical constant number
we have
[tex]t=1\ years\\ P=\$10,000\\ r=0.08[/tex]
substitute in the formula above
[tex]A=\$10,000(e)^{0.08*1}=\$10,833[/tex]
Compound interest computed continuously after one year on a principal sum of $10,000 with an 8% interest rate will yield $10,833, rounded to the nearest dollar.
Explanation:Your question relates to the mathematics topic of compound interest. When interest is compounded continuously, we use the formula A = P * e^(rt), where A is the amount of money accumulated after n years, including interest. P is the principal amount (the initial amount of money), r is the annual interest rate (in decimal form), and t is the time in years.
In your case, you are looking to find how much $10,000, invested at a nominal 8% per year compounded continuously, would amount to at the end of one year. Substituting the given values into the formula, we have:
A = $10,000 * e^(0.08*1).
The value of 'e' is approximately 2.71828. Therefore, we calculate:
A = $10,000 * 2.71828^0.08 = $10,833.
So, the amount in the account at the end of one year, rounded to the nearest dollar, would be $10,833.

Step-by-step explanation:
Remember that the standard exponential function is [tex]y=ab^x[/tex]
where
[tex]a[/tex] is the coefficient
[tex]b[/tex] is the base
If [tex]b>0[/tex], the function is growing
If [tex]0<b<1[/tex] the graph is decaying
We can infer from the graph that the function is growing, so we can discard [tex]y=0.45^x[/tex] and [tex]y=0.73^x[/tex].
Now, to evaluate our tow remaining equations, we are using the test values [tex]x=0[/tex] and [tex]x=1[/tex]:

For [tex]x=1[/tex]
[tex]y=1.8^1[/tex]
[tex]y=1.8[/tex]
The graph passes through the points (0,1) and (1, 1.8)
For [tex]y=3.9^x[/tex]
[tex]x=0[/tex]
[tex]y=3.9^0[/tex]
[tex]y=0[/tex]
[tex]x=1[/tex]
[tex]y=3.9^1[/tex]
[tex]y=3.9[/tex]
The graph passes through the points (0,1) and (1, 3.9)
We can see in the graph when [tex]x=1[/tex], [tex]y[/tex] is almost 4, so we can conclude that the correct equation is [tex]y=3.9^x[/tex]

cosA = AM/AT = (3√17)/13
tanA = MT/AM = 4/(3√17) = (4√17)/51
sinT = AM/AT = (3√17)/13
cosT = MT/AT = 4/13
tanT = AM/MT = (3√17)/4

The ratio of boys to girls in a group is 5:3. If there are 16 more boys than girls, work out how many people there are in total.
We find that there are 24 girls and 40 boys, leading to a total of 64 people in the group.
To solve for the total number of people in the group given the ratio of boys to girls and the information that there are 16 more boys than girls, we can set up a proportion based on the ratio 5:3. Let the number of girls be represented by x and the number of boys be represented by x + 16, as there are 16 more boys than girls. From the ratio 5:3, we know that for every 8 parts (5+3), there are 5 parts boys and 3 parts girls. This gives us two equations: 5/8 of the total is boys, and 3/8 of the total is girls.
From the information given:
(x + 16) / x = 5 / 3
Cross-multiplying gives us:
3(x + 16) = 5x
3x + 48 = 5x
48 = 5x - 3x
48 = 2x
x = 24
This means there are 24 girls. Since there are 16 more boys, this means there are 24 + 16 = 40 boys. Adding up the boys and girls gives us the total number of people in the group:
40 boys + 24 girls = 64 people in total.

Answer: [tex]x=\frac{37}{9}[/tex]
Step-by-step explanation:
By the negative exponent rule, you have that:
[tex](\frac{1}{a})^n=a^{-n}[/tex]
By the exponents properties, you know that:
[tex](m^n)^l=m^{(nl)}[/tex]
[tex](m^n)(m^l)=m^{(n+l)}[/tex]
Rewrite 4, 8 and 32 as following:
4=2²
8=2³
32=2⁵
Rewrite the expression:
[tex](2^2)^{(x-7)}*(2^3)^{(2x-3)}=\frac{32}{2^{(x-9)}}[/tex]
Keeping on mind the exponents properties, you have:
[tex](2)^{2(x-7)}*(2)^{3(2x-3)}=32(2^{-(x-9)}[/tex]
[tex](2)^{2(x-7)}*(2)^{3(2x-3)}=(2^5)(2^{-(x-9)})\\\\(2)^{(2x-14)}*(2)^{(6x-9)}=(2^5)(2^{(-x+9)})\\\\2^{((2x-14)+(6x-9))}=2^{(5+(-x+9))}[/tex]
As the bases are equal, then:
[tex](2x-14)+(6x-9)=5+(-x+9)\\\\2x-14+6x-9=5-x+9\\\\8x-23=14-x\\9x=37[/tex]

Answer:

Step-by-step explanation:
We are given the following linear equation and we are to solve it:
[tex] 4 ^ { x - 7 } \times 8 ^ { 2x - 3 } = \frac { 32 } { x ^ { x - 8 } } [/tex]
Changing the constants to the same base to make it easier to solve:
[tex] 2 ^ { 2 ( x - 7 ) } \times 2^ { 3 ( 2x - 3 ) } = \frac { 2 ^ 5 } { 2 ^ { x - 9 } } [/tex]
[tex]2^{2x-14} \times 2^{6x-9} = 2^{5}(2^{-x+9})[/tex]
[tex] 2 ^ { 2x - 14 + 6x - 9 } = 2 ^ { 5 - x + 9 } [/tex]
[tex] 2 x + 6x - 14 - 9 = 5 - x + 9 [/tex]
[tex]8x+x=14+9+5+9[/tex]
