Answer:

14.95

Step-by-step explanation:

Use a median calculator

Final answer:

To find the number in the middle of 8.6 and 21.3, you calculate their average by adding them together and dividing by two, resulting in 14.95.

Explanation:

To calculate the number in the middle of 8.6 and 21.3, we need to find the average of these two numbers. To do this, you add the two numbers together and then divide by two.

The calculation is therefore: (8.6 + 21.3) / 2.

Adding 8.6 and 21.3 gives us 29.9, and dividing 29.9 by 2 gives us 14.95. So, 14.95 is the number in the middle of 8.6 and 21.3.

Answer:

75.5

Step-by-step explanation:

The correct height of the flower basket above the ground is 75.5 inches.

To determine the height of the flower basket above the ground, we can use trigonometry. The camera forms a 25 ° angle of elevation with the flower basket, and the distance from the camera to the base of the rod is given as 72 inches. We also know that the camera is positioned 42 inches above the ground.

We can use the tangent function, which relates the angle of elevation to the opposite side (the height of the flower basket above the camera's height) and the adjacent side (the horizontal distance from the camera to the rod).

Let's denote the total height of the flower basket above the ground as h, and the height of the camera above the ground as [tex]h_c[/tex] = 42 inches. The height of the flower basket above the camera is then [tex]\( h - h_c \)[/tex].

Using the tangent function:

[tex]\tan(25\°) = \frac{\text{opposite}}{\text{adjacent}}[/tex]

[tex]= \frac{h - h_c}{72}[/tex]

We can solve for h:

[tex]\[ h - h_c = 72 \times \tan(25\°) \][/tex]

[tex]\[ h = 72 \times \tan(25\°) + h_c \][/tex]

Now we calculate the value of tan(25°) and substitute the known values:

[tex]\[ h = 72 \times \tan(25\°) + 42 \][/tex]

Using a calculator, we find that 25° is approximately 0.4663. Plugging this value into the equation gives us:

h = 72 x 0.4663 + 42

h = 33.5 + 42

h = 75.5

Therefore, the flower basket is approximately 75.5 inches above the ground.

Final answer:

To determine Miguel's total cost including the 8% sales tax, add the pre-tax total of $20.98 to the sales tax amount, which is calculated as $20.98 multiplied by 0.08, totaling $22.66.

Explanation:

To calculate Miguel’s total cost including an 8% sales tax on his purchases, follow these steps:

First, find the total cost before tax by adding the prices of the items. If Miguel bought items totaling $20.98, this is the pre-tax total.

Next, convert the tax percentage to a decimal form. For an 8% sales tax, this is done by dividing by 100, which gives us 0.08.

Then, calculate the amount of sales tax by multiplying the pre-tax total by the decimal tax rate: $20.98 × 0.08 = $1.6784.

Round the sales tax to the nearest cent, which gives us $1.68.

Finally, add the sales tax to the pre-tax total to find the total cost: $20.98 + $1.68 = $22.66.

The total cost for Miguel after adding the 8% sales tax is $22.66.

Answer:

$241.58

Step-by-step explanation:

he amount of money A, accrued at the end of n years when a certain amount, P is invested at a compound annual rate, r, is given by:

[tex]A=P(1+r)^n[/tex]

From the given information:

P =$150

r=10%=0.1

n= 5 years

Therefore the balance after 5 years is:

[tex]A=P(1+r)^n\\=150(1+0.1)^5\\=150*1.1^5\\=\$241.58[/tex]

The balance of the account after 5 years, with an initial investment of $150 and an annual interest rate of 10%, compunded annually, would be approximately $241.58.

To find the balance of the investment after 5 years, we substitute the values into the given formula. P is the principal amount which is $150, r is the annual interest rate which is 10% or 0.10 in decimal form, and n is the number of years which is 5. So the formula becomes A = $150 * (1 + 0.10)^5.

To simplify, calculate 1 + 0.10 to get 1.1. Then raise 1.1 to the power of 5 to get 1.61051. Multiply that by $150 to get approximately $241.58. So, the balance of the investment after 5 years would be approximately $241.58.

Answer:

i times the square root of 3

Step-by-step explanation:

Whenever you take a square root of a number, look for anything that you could take out! Like if you have the square root of 40, that’s 4 * 10, so you could take out a 2 from the square root and leave the 10.

In this, we see that it’s the square root of 3 times the square root of -1, which we can simplify to the square root of 3 times “i.” We use i to represent the square root of -1.

A perpendicular bisector is a line segment that goes form a vertex to its opposite side. The important characteristic is that a perpendicular bisector intersects the opposide at the mid point and with a right angle, that's why is called perpendicular and bisector.

So, Andrew can conclude that side BC is divide equally, that is, BD = DC.

Therefore, the right answer is the second choice.

Based on the given information after drawing the triangle Andrew can conclude only  BD = DC.

Use the concept of triangle defined as:

A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.

Given that,

Andrew draws triangle ABC.

He constructs a perpendicular bisector from vertex A.

The perpendicular bisector intersects side BC at point D.

Based on Andrew's drawing,

He can conclude that BD is equal to DC.

The perpendicular bisector from vertex A divides side BC into two equal parts, making BD and DC congruent.

However, Andrew cannot conclude that AB is equal to BC,

AD is equal to BC, or AC is equal to BC based on the given information.

Hence,

For this triangle Andrew can conclude only BD = DC.

Answer:

False - Linear is a proportional relationship as it is a straight line.

False.

False. A proportional relationship is linear. In a proportional relationship, when one variable increases or decreases, the other variable also increases or decreases at a constant rate. This results in a straight-line graph passing through the origin (0,0). In contrast, a non-linear relationship does not exhibit constant rate of change and does not form a straight line when graphed.

Complete correct question:

True or False

A proportional relationship is non- linear.

The diameter of the cone is 4√3 cm, which is approximately 6.93 cm when rounded to two decimal places.

To find the diameter of the cone, we first need to identify the formula for the volume of a cone, which is V = (1/3)πr^2h. Given that the volume (V) of the ice cream cone is 12π cubic cm and the height (h) is 9 cm, we can set up the equation to solve for the radius (r):

12π = (1/3)πr^2(9)

We can simplify this equation by dividing both sides by π and multiplying both sides by 3/9 (which is the reciprocal of 1/3 times 9):

12 = r^2

Therefore, r = √12 cm. To find the diameter, which is twice the radius, we calculate:

Diameter = 2r = 2(√12) cm = 2(√4√3) cm = 4√3 cm

The diameter of the cone is 4√3 cm or approximately 6.93 cm when rounded to two decimal places.
