Answer:

A

Step-by-step explanation:

Just square all of them to find 64

The square roots of 64 are -8 and 8. Neither 32 nor 64 1/2 are square roots of 64.

The square root of a number is a value that, when multiplied by itself, gives the original number. When dealing with real numbers, remember that a number can have two square roots: a positive root and a negative root.

For the number 64, we know 8 * 8 equals 64, so 8 is a square root. As a negative number multiplied by a negative number results in a positive number, -8 * -8 also equals 64. Therefore -8 is also a square root of 64.

Option A, -8, and B, '(64) 1/2' or -8, are correct. The square root of 64 is not 32 and 64 1/2.

Step-by-step explanation:

Answer: a) 1060, b) [tex]\dfrac{61}{167}[/tex]

Step-by-step explanation:

Since we have given that

Number of boys = 870

Number of girls = 800

Probability that a boy chosen studies Spanish = [tex]\dfrac{2}{3}[/tex]

Probability that a girl chosen studies Spanish = [tex]\dfrac{3}{5}[/tex]

So, the number of boys in the school who study Spanish would be

[tex]\dfrac{2}{3}\times 870=290\times 2=580[/tex]

So, the number of girls in the school who study Spanish would be

[tex]\dfrac{3}{5}\times 800\\\\=3\times 160\\\\=480[/tex]

So, total number of students who study Spanish would be :

[tex]480+580=1060[/tex]

b) What is the probability, as a fraction in its simplest form, that a student

chosen at random from the whole school does not study Spanish?

​Number of students who do not study Spanish would be:

[tex](870+800)-1060\\\\=1670-1060\\\\=610[/tex]

So, the probability of students who does not study Spanish would be :

[tex]\dfrac{610}{1670}=\dfrac{61}{167}[/tex]

Hence, a) 1060, b) [tex]\dfrac{61}{167}[/tex]

There are 1060 students who study Spanish in the school. The probability that a student chosen at random from the whole school does not study Spanish is 610/1670.

To work out the number of students in the school who study Spanish, we need to find the number of boys and girls who study Spanish and add them together. The probability that a boy chosen at random studies Spanish is 2/3. So the number of boys who study Spanish is 870 * (2/3) = 580. The probability that a girl chosen at random studies Spanish is 3/5. So the number of girls who study Spanish is 800 * (3/5) = 480. Therefore, the total number of students who study Spanish is 580 + 480 = 1060.

To find the probability that a student chosen at random from the whole school does not study Spanish, we subtract the probability that a student does study Spanish from 1. The probability that a student does study Spanish is 1060 (students who study Spanish) divided by 1670 (total number of students in the school). Therefore, the probability that a student does not study Spanish is 1 - (1060/1670) = 610/1670, which is already in its simplest form.

There are 8 people who attended the park.

To solve the problem, let's define the variables and write an equation. Let x be the number of people who attended. The total cost is the sum of the parking fee plus the admission fees.

The parking fee is $8.50, and the admission fee per person is $27.50. Therefore, the total cost can be expressed as:

Total Cost = Parking Fee + (Admission Fee per Person * Number of People)

This simplifies to:

$228.50 = $8.50 + $27.50 * x

First, subtract the parking fee from the total cost:

$228.50 - $8.50 = $27.50 * x

$220 = $27.50 * x

Now, divide both sides by the admission fee per person to find x:

x = $220 / $27.50

x = 8

Thus, 8 people attended the park.

Step-by-step explanation:

The area of the circular base is 707 square feet, calculated using the formula A = πr², where π is 3.14 and the radius is 15 feet.

The question asks for the area of a circular base of a statue with a given radius. This is a question of geometry, and the formula for the area of a circle is A = πr², where A represents the area and r represents the radius. In this case, the radius given is 15 feet.

To calculate the area, we insert the value of the radius into the formula, so it becomes A = π(15)². Since we are asked to use 3.14 for π, the calculation becomes: A = 3.14 * 15², which equals 706.5 square feet.

However, since we have been asked to round to the nearest whole number, the final answer would be 707 square feet.

To find the area of the circular base of the statue, we can use the formula A = πr^2, where A is the area and r is the radius. In this case, the radius is given as 15 feet. Plugging this value into the formula, we get:

A = 3.14 * 15^2 = 3.14 * 225 = 706.5 square feet

Rounding to the nearest whole number, the area of the base is approximately 707 square feet.

Where the graphs of the functions intersect it represents the number of weeks when they have both saved the same amount of money. So by solving the system we can find the number of weeks and that amount of money.

y = x^2 + 2x

y = -3x + 6 so

x^2 + 2x = -3x + 6

x^2 + 5x - 6 = 0

(x + 6)(x - 1) = 0

So x = 1  ( we ignore the negative)

So after 1 week  they have saved the same amount  and the amount is -3 + 6 = 3.

Answer:

The sprinkler can spread water in a radius of 24 feet.

Step-by-step explanation:

Since the sprinkler sends water in a circular pattern in order to find the distance at which it can spread the water we need to find the radius of the circle. The area of the circle is said to be 1808.64 and it's formula is given by:

area = pi*r²

1808.64 = 3.14*r²

r² = 1808.64/3.14 = 576

r = sqrt(576) = 24 feet

The sprinkler can spread water in a radius of 24 feet.

The equation y = 2x + 2 is a function, because each 'x' value corresponds to a single 'y' value, as per the mathematical definition of a function.

The graph of the equation y = 2x + 2 does indeed represent a function. In mathematics, a function is defined as a relation in which each input (or 'x' value) corresponds to exactly one output (or 'y' value). In the given coordinate pairs, you will notice that each individual 'x' value (such as -1, 0, 1, and 2) corresponds to a single 'y' value. Furthermore, the equation itself, y = 2x + 2, will always yield a single 'y' value for each 'x' value you substitute into it. This aligns with the definition of a function. Hence, the equation y = 2x + 2 is a function.

Step-by-step explanation:

The amount of money in the account after 3 years would be $828.

To determine the amount of money in the account after 3 years, we need to find the number of times the money doubles in a period of 3 years, given that it doubles every 7 years. To find this, we divide 3 by 7 to get the number of doubling periods which is approximately 0.4286. Since the money doubles every 7 years, we multiply the initial investment of $690 by 2 raised to the power of 0.4286 to find the final amount.

Using the formula A = P(1+r)^n, where A is the final amount, P is the initial investment, r is the interest rate per period, and n is the number of periods, we have P = $690, r = 100% (as the money doubles), and n = 0.4286. Substituting these values into the formula, we get A ≈ $827.84. Hence, the amount of money in the account after 3 years, to the nearest dollar, would be $828.

Final answer:

To calculate the future value of an investment that doubles every 7 years after 3 years, we use the exponential growth formula with an annual interest rate determined by the Rule of 70, resulting in approximately $918.

Explanation:

To determine how much money will be in the account after 3 years given that the amount doubles every 7 years, we can use the formula for exponential growth. The formula is A = P(1 + r/n)nt, 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 (as a decimal), n is the number of times that interest is compounded per year, and t is the time the money is invested for in years.

Since the money doubles every 7 years, the effective annual interest rate 'r' that would cause this can be found using the Rule of 70. The Rule of 70 states that to find the number of years required to double the money at a given interest rate, you divide 70 by the annual interest rate. Here, we have that number already (7 years), so we can rearrange to find the interest rate: rate = 70 / time to double. Therefore, the interest rate is 70 / 7, which equals 10% or 0.10 as a decimal.

However, we are looking for the amount after 3 years, not 7. Thus, we need to adjust our formula to account for this shorter time period:

A = P(1 + r)^t
A = 690(1 + 0.10)^3
A = 690(1.331)
A ≈ $918

So, after 3 years, the investment would grow to approximately $918, to the nearest dollar.
