Answer:10,400

Step-by-step explanation:

Assuming he drives at a speed of 60 miles per hour, it will take him 5.5 hours to drive the 330 miles.

If Harold drives 330 more miles at the same rate of 60 miles per hour, we can use the formula:

distance = rate x time

Let t be the time in hours it takes to drive the additional 330 miles. Then we have:

330 = 60t

Solving for t, we get:

t = 330/60

t ≈ 5.5 hours

Therefore, it takes approximately 5.5 hours to drive the additional 330 miles at a rate of 60 miles per hour.

the interest earned on 250000 at a 7.5% interest rate for half a year is 4687.50. This means that after half a year, the total amount that you would have is the sum of the principal and the interest, which is 254687.50.

To calculate the interest on 250000 at a 7.5% interest rate for half a year, we first need to determine the annual interest rate, as most interest rates are quoted on an annual basis. To do this, we can divide the annual interest rate of 7.5% by 2 to get the half-yearly interest rate, which is 3.75%.

Next, we can use the formula for simple interest to calculate the interest earned over half a year. Simple interest is calculated by multiplying the principal amount (in this case, 250000) by the interest rate (3.75%) and the time period (0.5 years).

So, the interest earned would be:

Interest = Principal x Rate x Time

= 250000 x 0.0375 x 0.5

= 4687.50

Therefore, the interest earned on 250000 at a 7.5% interest rate for half a year is 4687.50. This means that after half a year, the total amount that you would have is the sum of the principal and the interest, which is 254687.50.

It's worth noting that this calculation assumes that the interest is simple interest, which means that the interest earned is not reinvested. If the interest is compounded (i.e., the interest earned is reinvested), then the interest earned would be higher.

The given function [tex]y=x^2 - 6x - 7[/tex] describes the graph A.

What is function?

In mathematics, a function is a relation between a set of inputs (the domain) and a set of possible outputs (the codomain) with the property that each input is related to exactly one output.

We can solve this Function by substituting the 0 for Y.

To find the value of x when y is equal to 0, we can substitute 0 for y in the equation and solve for x:

[tex]0 = x^2 - 6x - 7[/tex]

To solve for x, we can use the quadratic formula:

x = (-b ± [tex]\sqrt{(b^2 - 4ac)}[/tex]) / 2a

In this case, a = 1, b = -6, and c = -7. Substituting these values into the formula, we get:

x = (-(-6) ± [tex]\sqrt {((-6)^2 - 4(1)(-7)}[/tex])) / 2(1)

Simplifying:

x = (6 ± [tex]\sqrt{64}[/tex]) / 2

x = (6 ± 8) / 2

x = 7 or x = -1

Therefore, when y is equal to 0, x can be either 7 or -1.

Therefore the given function describes the graph A.

Answer:

The diameter of the circle is 12 inches, which means the radius of the circle is half of the diameter, or 6 inches.

The formula for the area of a circle is:

A = πr^2

where A is the area of the circle and r is the radius.

Plugging in the value for the radius, we get:

A = π(6 in)^2

A = π(36 in^2)

A = 113.1 in^2 (rounded to one decimal place)

Therefore, the area of the circle is approximately 113.1 square inches.

A gallon of milk is approximately 4 liters. 250 gallon containers of air will it take to full one cubic meter.

The setup for calculating how many gallon containers of air it will take to fill one cubic meter is:

1 m³ × 1000 L/m³ ÷ 4 L

A gallon of milk is approximately equal to 4 liters.

1 cubic meter (1 m³) of air is equal to 1000 liters.

One cubic foot of water contains 7.48 gallons. Dividing the total number of gallons by 7.48 will get the cubic feet equivalent.

To convert liters to gallons,

divide by 4 (since 1 gallon is approximately equal to 4 liters).

The calculation for how many gallon containers of air it will take to fill one cubic meter is:

The area of the figure composing of a rectangle and a semi-circle is 105.12 ft².

The figure in the image composes of a rectangle and a semi-circle.

The area of a rectangle is expressed as;

Area = Length × Width

The area of a semi-circle is expressed as;

Area = 1/2 × πr²

First, we find the area of the rectangle.

Area = Length × Width

Plug in Length = 10ft and Width = 8ft

Area = 10ft × 8ft

Area = 80ft²

Next, find the area of the semi-circle.

Area = 1/2 × πr²

Since diameter = 8ft, radius r = diameter/2 = 8ft/2 = 4ft

Area = 1/2 × 3.14 × (4ft)²

Area = 1/2 × 3.14 × 16 ft²

Area = 25.12 ft²

Now, area of the composite figure will be:

Area of the rectangle + Area of the semi-circle.

Area = 80ft² + 25.12 ft²

Area = 105.12 ft²

Therefore, the area of the figure is 105.12 ft².

In Linear pair, 52°  is the value ∠AZJ .

What is Linear pairs?

When two lines meet at a single point, a pair of linear angles is created. If, following the junction of the two lines, the angles are next to one another, they are said to be linear. A linear pair's total angles are always equal to 180 degrees.

                                   A pair of adjacent angles is said to be a linear pair if the total of the two angles' (measured) angles is 180°. This means that a linear pair of angles always adds up to 180°. The linear pair of 30°, for instance, is 150°; the linear pair of 70°, 110°; etc.

∠JZF or ∠HZG

Linear pairs form supplementary angles.

The probability of selecting a vowel from a hat with letters of the alphabet is 5/26 or approximately 0.1923. There are 5 vowels and 26 total letters.

There are 5 vowels in the English alphabet: A, E, I, O, and U. Therefore, the number of favorable outcomes (i.e., the number of vowels in the hat) is 5.

There are a total of 26 letters in the English alphabet. Therefore, the number of possible outcomes (i.e., the number of letters in the hat) is 26.

The probability of selecting a vowel is the ratio of the number of favorable outcomes to the number of possible outcomes:

P(vowel) = number of favorable outcomes / number of possible outcomes

P(vowel) = 5 / 26

Step-by-step explanation:

Because the critical region is all on one side in a one-tailed test and needs to be split between the two tails in a two-tailed test.

In a one-tailed test, the alternative hypothesis is directional and the critical region is all on one side of the distribution. In a two-tailed test, the alternative hypothesis is non-directional and the critical region is split between the two tails of the distribution.

It is easier to reject the null hypothesis with a one-tailed test because the critical region is all on one side of the distribution, making it more likely to observe a significant difference and reject the null hypothesis. In contrast, the critical region is split between the two tails in a two-tailed test, making it less likely to observe a significant difference and reject the null hypothesis.

The simplified form of the polynomial expression in standard form is: - x² - 8x - 8

The standard form of a polynomial is usually expressed by writing the highest degree of terms first then the next degree and so on. The standard form of polynomial is given by, f(x) = aⁿxⁿ + aⁿ⁻¹xⁿ⁻¹ + aⁿ⁻²xⁿ⁻² + ... + a₁x + a₀, where x is the variable and a_i are coefficients.

The polynomial expression is given as (x+4)² is subtracted from 8. Thus, we have:

8 - (x+4)²

Expanding gives:

8 - (x² + 8x + 16)

= 8 - x² - 8x - 16

= - x² - 8x - 8
