The best estimate for the sum of 5/6 and 3/7 by rounding to the nearest 0, 1/2, or 1 is 1.5 or 3/2.
To estimate the sum of 5/6 and 3/7, we round each addend to the nearest of the given values: 0, 1/2 (0.5), or 1. Five-sixths is closer to 1 than it is to 1/2 or 0. So, we round 5/6 to 1.
Three-sevenths is closer to 1/2 than to 1 or 0. So, we round 3/7 to 1/2. After rounding, our new equation for estimation is 1 + 1/2.
The best estimate for the sum thus becomes 1 + 1/2 which equals 1.5 or 3/2. This is a quick way to find a rough estimate of the sum without finding a common denominator or adding the actual fractions.
You are dealt one card from a 52- card deck. Find the probability that you are not dealt a six
Answer:
48/52, or 0.92307692307
Step-by-step explanation:
There are 13 cards in each of the 4 suits.
A,2,3,4,5,6,7,8,9,10,J,Q,K.
If there is 1 six in 1 suit, and there are 4 suits, there are 4 sixes. The chance of NOT getting a 6 is 52(all the cards)-4(six delt) /52.
48/52=0.92307692307
Want it more professionally?
Using the scientific probability method:
p=probability
p(all cards in 1 deck)-p(a 6 dealt)=p(not dealt a 6)
p(52/52)-p(4/52)=p(not dealt a 6)
p(48/52)=p(not dealt a 6)
There is a 48/52 chance (0.92307692307) that you are not dealt a 6.
Hope this helps!
The probability of not being dealt a six from a 52-card deck is 12/13.
Probability of not being dealt a six:
There are 52 cards in a deck.
There are 4 sixes in a deck .
Hence, the probability of not getting a six when dealt one card is 1 - (4/52) = 48/52 = 12/13.

Answer:
The correct answer is:
Ken will have run 3 laps and Hamid will have run 4.
Explanation:
To find this, we first find the number of seconds that will have passed when they meet again. We use the LCM, or least common multiple, for this. First we find the prime factorization of each number:
80 = 10(8)
10 = 5(2)
8 = 2(4)
4 = 2(2)
80 = 2(2)(2)(5)(2)
60 = 10(6)
10 = 5(2)
6 = 2(3)
60 = 2(2)(3)(5)
For the LCM, we multiply the common factors by the uncommon. Between the two numbers, the common factors are 2, 2 and 5. This makes the uncommon 2, 2, and 3, and makes our LCM
2(2)(5)(2)(2)(3) = 240
This means every 240 seconds they will both be at the start line.
Since Ken completes a lap in 80 seconds, he completes 240/80 = 3 laps in 240 seconds.
Since Hamid completes a lap in 60 seconds, he completes 240/60 = 4 laps in 240 seconds.

A factory sells backpacks for $35 each. The cost to make 1 backpack is $15. In addition to the cost of making backpacks, the factory has operating expenses of $11,000 per week. The factory's goal is to make a profit of at least $7,800 per week. Write and solve an inequality that represents the number of backpacks, x, that need to be sold? *
Answer:9400 backpacks
[tex]\geq[/tex]Step-by-step explanation
since the number of packs to be sold in a is represented by x,
selling price for 1 week = 35x
cost price for 1 week = 15x
profit = 35x-15x = 20x
additional cost of production = 11,000
this implies that 20x - 11,000 [tex]\geq[/tex] 7800
20x - 11,000 [tex]\geq[/tex] 7,800
20x [tex]\geq[/tex] 7800+ 11000
20x [tex]\geq[/tex] 18,800
x [tex]\geq[/tex] 18800/2
x [tex]\geq[/tex] 9,400
at least 9,400 packs have to be sold each week to make a profit of $7800

Check the picture below.
A)
well, we start off by making a table of values for the function, with a few "t" values, as you see in the picture, then graph those points to get the graph.
B)
at t = 0, h(0) = 98, and at t = 1, h(1) = 82, so it went from 98 to 82, for a difference of 16.
C)
at t = 1, h(1) = 82, and at t = 2 h(2) = 34, so it went from 82 to 34, for a difference of 48.
does it fall the same distance on both intervals? well, they're different, so nope.
which pair of points forms line that does no intersect the line that passes through the points (5,7) and (7,7)?
Answer:
(8, -9), (11, -9)
Step-by-step explanation:
The points (5, 7) and (7, 7) are on a horizontal line in which the y-coordinates of all points are 7. The line has equation y = 7.
For a line to not intersect the line y = 7, it must be parallel to y = 7.
The answer is the pair of points which both have the same y-coordinate, and that y-coordinate is not 7.
From the choices you added to your comments, the only choice with two points with the same y-coordinate is (8, -9) and (11, -9). This is the answer.
Answer: (8, -9), (11, -9)

factor q^2+q+5pq+5p by grouping
Answer:
(q + 1)(q + 5p)
Step-by-step explanation:
q² + q + 5pq + 5p
= (q² + q) + (5pq + 5p)
Consider that : q² + q = q(q + 1) and 5pq + 5p = 5p(q + 1)
then
q² + q + 5pq + 5p
= (q² + q) + (5pq + 5p)
= q(q + 1) + 5p(q + 1)
= (q + 1)(q + 5p)
Good luck :)
Final answer:
The expression q^2 + q + 5pq + 5p is factored by grouping into (q + 5p)(q + 1) by factoring out common factors from the grouped terms.
Explanation:
To factor by grouping the expression q2 + q + 5pq + 5p, we need to group the terms in a way that common factors can be factored out.
Firstly, we divide the expression into two groups:
q2 + q5pq + 5pWe can then factor out the common factor from each group:
q2 + q = q(q + 1)5pq + 5p = 5p(q + 1)Now, we can see that the term (q + 1) is common in both grouped expressions:
q(q + 1) + 5p(q + 1)
The expression can be factored as:
(q + 5p)(q + 1)
This is the factored form of the original expression.
The diagram shows a sector of a circle of radius 6 units, formed from an angle of size 305°.
Find the exact length of the arc.
3050
The length of the arc is 31.92 units
Explanation:
Given that the sector of a circle of radius 6 units.
The angle is given by [tex]\theta=305^{\circ}[/tex]
Arc length of the circle:
The arc length of the circle can be determined using the formula,
[tex]\ {arc\ length}=2 \pi r\left(\frac{\theta}{360}\right)[/tex]
where r = 6 and [tex]\theta=305^{\circ}[/tex]
Substituting the values, we have,
[tex]\ {arc\ length}=2 \pi (6)\left(\frac{305}{360}\right)[/tex]
Multiplying the numerator, we have,
[tex]\ {arc\ length}=\frac{3660 \pi}{360}[/tex]
Substituting [tex]\pi=3.14[/tex], we have,
[tex]\ {arc\ length}=\frac{3660(3.14)}{360}[/tex]
Multiplying the terms, we get,
[tex]\ {arc\ length}=\frac{11492.4}{360}[/tex]
Dividing, we get,
[tex]\ {arc\ length}=31.92 \ units[/tex]
Thus, the arc length of the circle is 31.92 units

If you bought a car five years ago for $15,000 and today you can sell for $7000 what was its rate of depreciation
Step-by-step explanation:
The price of car purchased 5 years ago = 15000
The price of car sold = 7000
By compound depreciation,
[tex]Pn = P (1 - R/100) ^ T[/tex] ... (1)
where Pn = 7000
P = 15000
R = rate of interest to be calculated
T = 5 ( number of years)
substituting the values in equation (1), we get
[tex]7000 = 15000 (1 - R/100) ^ 5[/tex]
[tex]0.46 = (1 - R/100) ^ 5[/tex]
[tex]0.858 = 1 - R/100[/tex]
0.858 is rounded off as 0.86
R/100 = 0.14
By simplifying the above equation, we get
Rate of depreciation = 14%

The sum of two numbers is 35.
Three times the larger number is
the same as 4 times the smaller
number. Find the larger number.
(HINT: Let x = larger number;
35 - X=smaller number.)
Answer:
Larger number(x)=20
Step-by-step explanation:
They're saying that the larger number 3 times is EQUAL(the same) to 4 times the smaller number.
The smallest number=35-x.
The larger number= x.
3 times the larger number=3x
4 times the smaller number=4(35-x)
Now, input it into an equation and solve:
3x=4(35-x) Distribute by multiplying 4 with 35 and x.
3x+4x=140-4x+4x Get 140 by itself by adding 4x.
7x/7=140/7 Divide.
x=20
Since x= the larger number, x=20.
To find the larger number when the sum of two numbers is given and the relationship between them is described, we can set up and solve an equation.
Explanation:To solve this problem, we can set up two equations based on the given information. Let x represent the larger number and 35 - x represent the smaller number. According to the problem, we have the equation 3x = 4(35 - x). Solving this equation will give us the value of x, which represents the larger number.
Expanding the equation, we have 3x = 140 - 4x. Combining like terms, we get 7x = 140. Dividing both sides by 7, we find that x = 20. Therefore, the larger number is 20.

An international company has 12,700 employees in one country. If this represents 27.1% of the company's employees, how many employees does it have in total?
The international company has 46864 employees in total.
Step-by-step explanation:
Given that,
An international company has 12,700 employees in one country.
And, this 12,700 employees represents 27.1% of the company's employees.
Therefore, the total number of employees can be found by calculating the 100% of the employees.
Let us assume that the total number of the employees be 'x'.
From the x number of employees, 12,700 employees were 27.1%
Now, framing the above statement in the equation form to solve for x :
⇒ 27.1 % of x = 12700
⇒ (27.1 / 100) x = 12700
⇒ 0.271 x = 12700
⇒ x = 12700 / 0.271
⇒ x = 46863.5 (which is approximately 46864 employees)
Therefore, the total number of employees is 46864.

Suppose you have $300 to invest. One bank offers an annual
simple interest rate of 4.5% for a 3-year investment. Another
bank offers an annual simple interest rate of 6.8% for a 2-year
investment. Which account will earn you more money?
Answer:
$40.50
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
I= P × r × t
Where:
P is the principal amount, which is $300.00.
r equals the interest rate, which 4.5% per year, or as a decimal, 4.5/100=0.045.
t equals time involved, which is 3 years
To find the simple interest, we multiply 300 × 0.045 × 3 to get that the interest is: $40.50
hope this helped! pls give a thanks:)

hi again, a ice cream shop uses the following ingredients to make 1 sundae.
ice cream=2 scoops
sprinkles=4 spoonfuls
wipped cream=2 tablespoons
how many sundaie's did the shop make if they used 32 spponfuls of sprinkles?
Answer:
8 sundaes.
Step-by-step explanation:
Follow below steps:
Combinations without repetition:
In the given scenario, the ice cream shop uses 4 spoonfuls of sprinkles for 1 sundae. To find out how many sundaes they made with 32 spoonfuls of sprinkles, divide the total number of spoonfuls by the amount of sprinkles used per sundae: 32 spoonfuls ÷ 4 spoonfuls = 8 sundaes.
Combinations with repetition:
Explaining combinations with repetition involves calculating the different combinations possible when taking into account repeated flavors in ice cream selections.
Ivanna made $414 for 18 hours of work.
At the same rate, how many hours would she have to work to make $115?
Answer:
5hours
Step-by-step explanation:
Ivanna made $414 for 18 hours of work.
Working at the same rate, she will make $115 for = (115 x 18)/414 = 5hours
Answer:
5
Step-by-step explanation:
First, we have to figure out how much money she makes per hour. We can do this by dividing. 414 divided by 18 = 23. Then, we multiply. 23 x 17 = 391, 23 x 16 = 368 etc. we multiply until we get to, 23 x 5, which equals 115. I hope this made sense!
How do you determine the base when solving for x by converting to a log?
The answer was supposed to be
x= ln(3/2) / 4ln(1.0125)
why is it ln?
[tex]$x=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}[/tex]
Solution:
Given expression:
[tex]$(1.0125)^{4 x}=\frac{3}{2}[/tex]
To solve the expression:
[tex]$(1.0125)^{4 x}=\frac{3}{2}[/tex]
If f(x) = g(x) then ln(f(x)) = ln(g(x)).
Using the above condition, we can write
[tex]$\ln \left(1.0125^{4 x}\right)=\ln \left(\frac{3}{2}\right)[/tex]
Apply log rule: [tex]\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)[/tex]
[tex]$4 x \ln (1.0125)=\ln \left(\frac{3}{2}\right)[/tex]
Divide both side of the equation by [tex]4 \ln (1.0125)[/tex].
[tex]$\frac{4 x \ln (1.0125)}{4 \ln (1.0125)}=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}[/tex]
[tex]$x=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}[/tex]
The answer is [tex]x=\frac{\ln \left(\frac{3}{2}\right)}{4 \ln (1.0125)}[/tex].
Final answer:
To solve for x by converting to a logarithm, the base used depends on the context and specific problem. In this case, the natural logarithm is used as the base is relevant to the equation.
Explanation:
To solve for x by converting to a logarithm, you need to determine the base of the logarithm. In this case, the answer is x = ln(3/2) / 4ln(1.0125), where ln represents the natural logarithm.
The natural logarithm, denoted by ln, is the logarithm with base e, where e is an irrational number approximately equal to 2.71828. It is commonly used in calculus and other fields of mathematics.
When converting to a logarithm, the base can be any positive number greater than 1. The choice of base depends on the context and the specific problem being solved. In this case, the natural logarithm is used because it is relevant to the given equation.

A circle has a circumference of 150 meters. What is the measure of its radius? Round
to the nearest tenth.
circumferend
What is the measure of its radius?
Answer:
R = 23.9
Step-by-step explanation:
formula for circles circumfrence is, C = 2*3.14*R
in this one we have to work backwards so we plug wut we have.
150 = 2* 3.14*R
we divide 150 by 2 so it will be
75 = 3.14R
now we divide 75 by pi so wwe get
23.8732414638 = R
Now we round it to nearest tenth
R = 23.9
1) A survey of favorite colors showed 198 people chose
green, 212 chose blue, and 187 chose red. If 39% of the
people surveyed are children, ABOUT how many
people surveyed were children? (use a calculator – show
all work!)
Answer:
233
Step-by-step explanation:
so we add up the total number of people surveyed (198+212+187) and get 597. So, then we multiply 597 by 0.39 (597(.39)) and that gives us 232.83. we round up 232.83 to 233 and thats the answer
