Answer:
An integer, a, cannot be divided by an integer, b, when [tex]b=0[/tex]
Step-by-step explanation:
There is only one limitation when dividing two numbers. This is that you cannot divide a number by 0 as it is impossible to divide something into 0 groups.
As the integer, b, is the number that symbolized the number of groups something is divided into, this value cannot be 0.

A grocery store sells a party mix in 640 g bags. The ratio of pretzels to corn
chips is 5: 3. Determine the mass of the pretzels in the bag.
Answer: 400g
Step-by-step explanation:
The ratio of pretzels to corn chips is 5:3, which means that pretzels make up 5/8 of the party mix.
Mass of pretzels = 5/8 x 640g = 400g

Clare has $5,003 in a savings account that earns 8% interest, compounded annually.
To the nearest cent, how much interest will she earn in 4 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer: Clare earned $6806.53.
Step-by-step explanation:
The formula given to us is the formula for compounded interest.
You can substitute the values given in the first part of the problem into the equation to find B, the final amount:
[tex]B = p*(1+r)^t\\\\B = 5003 * (1 + 0.08)^4[/tex]
Note that 8% interest is expressed as 0.08 because it is a percentage of a whole number.
Now, use a calculator to raise 1.08 to the fourth degree to get this:
[tex]B = 5003 * 1.360488\\B = 6806.526[/tex]
As such, Clare earned $6806.53 in interest after 4 years.

Here are the first four terms of an arithmetic sequence.
5
12
19
26
Write down an expression, in terms of n, for the nth term of the sequence.
Answer:
nth term = 7n - 2
Step-by-step explanation:
The first 4 term of the arithmetic sequence is 5, 12 , 19 and 26. The expression in terms of nth term that model this sequence can be express below
The nth term of the arithmetic sequence form can be represented as follows.
nth = a + (n - 1)d
where
a = first term
d = common difference
Therefore,
a = 5
d = 12 - 5 = 7 or 19 - 12 = 7 or 26 - 19 = 7
nth = a + (n - 1)d
nth term = 5 + (n - 1)7
nth term = 5 + 7n - 7
nth term = 7n - 2

Question:
James has 14,500g of sand in his sandbox. He brings home another 7,400g of sand from the beach to add to his sandbox. How many kilograms of sand does James have in his sandbox now?
Answer:
The quantity of sandbox James has is 21.9kg
Step-by-step explanation:
Given
Initial quantity of sandbox = 14,500 g
Additional quantity = 7,400 g
Required
Total quantity of sandbox in kg
Tp get the total quantity of sandbox, we simply add in the initial and additional quantity of sandbox together;
This is represented mathematically as follows;
Total = Initial Quantity + Additional Quantity
Total = 14,500 g + 7,400 g
Total = 21,900 g
But the question says the answer should be in kg
1000 g is equivalent to 1 kg
21,900 g will be equivalent to [tex]\frac{21,900}{1,000} kg[/tex]
[tex]21,900g = \frac{21,900}{1,000} kg[/tex]
[tex]21,900g = 21.9 kg[/tex]
Hence, the quantity of sandbox James has is 21.9kg

a) 21 400 b) 15 800 c) 10 400 d) 10 800
Answer:
d) 10 800
Step-by-step explanation:
Um ângulo é considerado raso quando sua medida é exatamente 180 graus, visto que cada grau equivale a 60 minutos, para obter a medida de um ângulo raso em minutos basta multiplicar 180 por 60:
[tex]180 *60=10800\ minutos[/tex]

Find an angle 0 coterminal to 801°, where 0° < 0 < 360°.
Answer:
[tex]\alpha' = 81^{\circ}[/tex]
Step-by-step explanation:
Angle is periodical function, so that following condition is satisfied:
[tex]\alpha = n \cdot 360^{\circ}[/tex]
[tex]n = \frac{801^{\circ}}{360^{\circ}}[/tex]
[tex]n = 2.225[/tex]
The position of the coterminal angle is:
[tex]n' = 2.225 - 2[/tex]
[tex]n' = 0.225[/tex]
[tex]\alpha' = n' \cdot 360^{\circ}[/tex]
[tex]\alpha' = (0.225)\cdot (360^{\circ})[/tex]
[tex]\alpha' = 81^{\circ}[/tex]

What is the median of the data: 1, 2, 3, 3, 5, 6, 8

What is the range of the data: 1, 2, 3, 3, 5, 6, 8
i need help fast
Median: The middle number in the data set when the
data set is written from least to greatest.
Since our data set is already written from least to greatest,
we can just look for the number that appears in the middle.
In this case, it would be 3.
Mode: The number that appears
most frequently in a data set.
Notice that the number 3 appears twice in the data set and no other
number appears more than once. So the mode is 3.
Range: The difference between the greatest number in
the data set and the least number in the data set.
Since the greatest number is 8 and the least number is 1,
the range of the data set will be 8 - 1 or 7.
A store is having a sale on walnuts and chocolate chips. For 12 pounds of walnuts and 2 pounds of chocolate chips, the total cost is $45. For 3 pounds of walnuts and 5 pounds of chocolate chips, the total cost is $18. Find the cost for each pound of walnuts and each pound of chocolate chips.
cost for each pound of walnuts:
cost for each pound of chocolate chips:
Answer:
Each pound of walnuts cost $3.50 and each pound of chocolate chips cost $1.50
Step-by-step explanation:
Let the cost of one pound of walnuts = $w
and the cost of one pound of chocolate chips = $c
Cost of 12 pounds of walnuts and 2 pounds of chocolate chips = $45
12w + 2c = 45 ------(1)
Cost of 3 pounds of walnuts and 5 pounds of chocolate chips = $18
3w + 5c = 18 --------(2)
Multiply equation (2) by 4 then subtract it from equation (1)
(12w + 2c) - (12w + 20c) = 45 - 72
-18c = -27
c = [tex]\frac{27}{18}[/tex]
c = $1.5
Substitute c = 1.5 in equation (1),
12w + 2(1.5) = 45
12w = 45 - 3
w = [tex]\frac{42}{12}[/tex]
w = $3.5
Therefore, each pound of walnuts cost $3.5 and each pound of chocolate chips cost $1.5
A locker combination consists of two non-zero digits. The digits in a combination are not repeated and range from 2 through 9.
Event A = the first digit is an odd number
Event B = the second digit is an odd number
If a combination is picked at random with each possible locker combination being equally likely, what is P(B|A) expressed in simplest form?
A. 3/8
B. 3/7
C. 1/2
D. 4/7
Answer:
3/7 (b)
Step-by-step explanation:
If a combination is picked at random with each possible locker combination being equally likely, the conditional probability P(B|A) is 3/7.
What is conditional probability?Conditional probability is defined as the likelihood of an event or outcome occurring, based on the occurrence of a previous event or outcome.
Probability of event A = P(the first digit is an odd number) = 4/8
Given that event A has already occurred, we need to calculate the probability of the occurrence of probability B.
The total possible outcomes are 7 (out of 8 one is used up in event A).
Favorable outcomes are 3 (out of 4 one is used up in event A).
P(B|A) = 3/7

Change the following mixed expressions to fractions and then simplify the complex fractions.
y-(4x^(5))/(x^(2)-xy)
Answer:
see below
Step-by-step explanation:
[tex]y-\frac{4x^5}{x^{2}-xy }[/tex] find common denominator and rewrite 1st part as a fraction
[tex]\frac{y(x^{2}-xy) }{x^{2}-xy }[/tex] [tex]-\frac{4x^5}{x^{2} -xy}[/tex]
[tex]\frac{x^{2}y - xy^2 -4x^5 }{x^{2} -xy}[/tex]
[tex]\frac{x(xy-y^2-4x^4}{x(x-y)}[/tex]
[tex]\frac{xy-y^{2}-4x^4 }{x-y}[/tex]
The expression [tex]y -\frac{4x^5}{x^2 - xy}[/tex] can be simplified as [tex]\frac{yx - y^2-4x^4}{x-y}[/tex]or [tex]y -\frac{4x^4}{x - y}[/tex].
What is Fraction?Fractions are numbers which has two parts, numerator and the denominator and is of the form p/q. Here, the number on the top p is called the numerator and the one on the bottom q is called the denominator.
Fractions can also be expressed and decimals and the reverse can also be applied.
Given expression is a mixed expression. We have to first change it into fractions and then have to simplify the complex fractions.
Given expression is [tex]y -\frac{4x^5}{x^2 - xy}[/tex].
First do the cross multiplication.
[tex]y -\frac{4x^5}{x^2 - xy}[/tex] = [tex]\frac{[y(x^2 - xy)]-4x^5}{x^2-xy}[/tex]
= [tex]\frac{(yx^2 - xy^2)-4x^5}{x^2-xy}[/tex]
= [tex]\frac{x(yx - y^2-4x^4)}{x(x-y)}[/tex]
= [tex]\frac{yx - y^2-4x^4}{x-y}[/tex]
= [tex]\frac{y(x - y)-4x^4}{x-y}[/tex]
= [tex]y -\frac{4x^4}{x - y}[/tex]
Hence the mixed expression given as [tex]y -\frac{4x^5}{x^2 - xy}[/tex] can be simplified as [tex]\frac{yx - y^2-4x^4}{x-y}[/tex] or [tex]y -\frac{4x^4}{x - y}[/tex].
