which of the following shows a strategy to use to find 4x275 (4x300)+(4x25)
(4x300)-(4x25) (4x275)-100 (4x200)+75
The correct strategy is (4x275) - 100. So option (3) is correct.
To find 4 multiplied by 275 using the given strategies, let's go through each one:
1. (4x300) + (4x25):
First, calculate (4x300) = 1200. Then, calculate (4x25) = 100. Finally, add these results together: 1200 + 100 = 1300.
2. (4x300) - (4x25):
Calculate (4x300) = 1200. Then, calculate (4x25) = 100. Now, subtract the second result from the first: 1200 - 100 = 1100.
3. (4x275) - 100:
Simply multiply 4 by 275 to get 1100. Then, subtract 100: 1100 - 100 = 1000.
4. (4x200) + 75:
Calculate (4x200) = 800. Then, add 75: 800 + 75 = 875.
The correct strategy is the third one: (4x275) - 100.
Detailed Calculation:
1. [tex]\(4 \times 275 = 1100\)[/tex]
2. [tex]\(1100 - 100 = 1000\)[/tex]
So, using the strategy of (4x275) - 100, the result is 1000.

Kevin and randy Muise have a jar containing 41 coins all of which are either quarters or nickels . The total value of coins in the jar is 7.45 how many of each type of coin do they have
To find the number of quarters and nickels, we can set up a system of equations using the total number of coins and the total value of the coins. Solving this system of equations, we find that Kevin and Randy have 27 quarters and 14 nickels.
Explanation:To solve this problem, we can set up a system of equations. Let's use the variables q (number of quarters) and n (number of nickels). We know that there are a total of 41 coins, so we can write the equation q + n = 41. We also know that the total value of the coins is $7.45, so we can write the equation 0.25q + 0.05n = 7.45.
Now we can solve this system of equations using substitution:
Isolate one variable in one of the equations. Let's isolate q in the first equation: q = 41 - n.Substitute this expression for q in the second equation: 0.25(41 - n) + 0.05n = 7.45.Simplify and solve for n: 10.25 - 0.25n + 0.05n = 7.45. Simplifying further, we get 0.20n = 2.80. Dividing by 0.20, we find that n = 14.Substitute this value of n back into the first equation to find q: q = 41 - 14 = 27.Therefore, Kevin and Randy have 27 quarters and 14 nickels in their jar.

The radius r of a circle is increasing at a rate of 8 centimeters per minute. find the rate of change of the area when r = 39 centimeters
The rate of change of the area of the circle when the radius is 39 centimeters is 1976π cm²/min. This uses the concept of related rates in calculus and the area formula A = πr².
Explanation:The problem deals with the concept of related rates in calculus. In this problem, we're looking at how the rate of change of the radius of a circle impacts the rate of change of the area of the circle. The formula for the area of a circle is A = πr².
Differentiating both sides with respect to time(t) gives dA/dt = 2πr(dr/dt). In this case, dr/dt (the rate of change of the radius) is given as 8 cm/min. To find dA/dt (the rate of change of the area) when r = 39 cm, we substitute these values into the differentiated equation: dA/dt = 2π(39cm)(8 cm/min) = 1976π cm²/min
So, the rate of change of the area when r = 39 centimeters is 1976π cm²/min. As the radius increases, the area of the circle increases at a rate directly proportional to the radius.

Write an explicit formula for the sequence (3,7,11,15,19,23,27,...)
The explicit formula for the given sequence is a_n = 3 + 4(n-1).
Explanation:The given sequence is (3, 7, 11, 15, 19, 23, 27, ...).
To find the explicit formula for this sequence, we can observe that each term is obtained by adding 4 to the previous term. So, the formula can be written as:
an = 3 + 4(n-1)
where n represents the position of the term in the sequence.
Standard 6 sided die is weighted so that the probabilities of rolling 2,3,4,5 or 6 are equal and the probability of rolling 1 is three times the probability of rolling a 2. if the die is thrown twice, what is the probability that the sum of the numbers thrown will be 4
There are 6 sides of the die, let us say that side 1 is S1, side 2 is S2 and so on.
Assigning a value of 3 to S1, so the probabilities are:
Probability
S1 = 3 3/8
S2 = 1 1/8
S3 = 1 1/8
S4 = 1 1/8
S5 = 1 1/8
S6 = 1 1/8
total = 8
The combinations that the sum of the two rolls will be 4 are:
S1 and S3
S3 and S1
S2 and S2
So the total probability is:
P = (3/8) * (1/8) + (1/8) * (3/8) + (1/8) * (1/8)
P = 0.1094 = 10.94%
So there is about 0.1094 or 10.94% probability that the sum will be 4.

The value V of a square glass varies directly as the square of its length X cm. If the value of a square glass with length 3 cm is $243, find the value of a glass with length 5 cm
The value V of a square glass varies directly as the square of its length X cm. This means that V is proportional to [tex]X^2[/tex], which can be expressed as:
[tex]\[ V = kX^2 \][/tex]
where k is the constant of proportionality.
Given that the value of a square glass with length 3 cm is $243, we can use this information to find the constant k:
[tex]\[ 243 = k(3)^2 \][/tex]
[tex]\[ 243 = 9k \][/tex]
[tex]\[ k = \frac{243}{9} \][/tex]
[tex]\[ k = 27 \][/tex]
Now that we have the value of k, we can find the value of a glass with length 5 cm by substituting X = 5 into the original equation:
[tex]\[ V = 27(5)^2 \][/tex]
[tex]\[ V = 27 \times 25 \][/tex]
[tex]\[ V = 675 \][/tex]
Therefore, the value of a glass with length 5 cm is $675.
The answer is: 675.

Find the quotient 4/6÷4/12
If the circumference of a circle is 201 centimeters what is the radius of the circle (to the nearest whole number)? Use 3.14 for pi
A) 32 centimeters
B) 128 centimeters
C) none
D) 16 centimeters
E) 64 centimeters
Final answer:
The radius of a circle with a circumference of 201 centimeters is approximately 32 centimeters, found by dividing the circumference by 2 times pi (π), using 3.14 as the value of pi. The correct answer is A) 32 centimeters.
Explanation:
The question asks us to find the radius of a circle when its circumference is given to be 201 centimeters. We use the circumference formula of a circle, which is C = 2πr, where C stands for circumference, π (pi) is a constant approximately equal to 3.14, and r represents the radius of the circle.
To find the radius, we rearrange this formula to solve for r:
Divide both sides of the equation by 2π to isolate r.
Plug in the given circumference value, C = 201 cm, and the approximate value of pi, π = 3.14, into the rearranged formula.
So the calculation would be r = C / (2π) = 201 / (2 * 3.14) = 201 / 6.28. When we compute this, we get r ≈ 32 centimeters to the nearest whole number.
Therefore, the correct answer is A) 32 centimeters.
