Answers

Answer:

3.1

Step-by-step explanation:

If you are doing this for big ideas, the answer ended up being 3.1

I'm sorry if you wanted the work, I found the answer from something else that didn't show the work but this was the correct answer...

Final answer:

To find the measure of BD⌓, the visible portion of Earth's surface from a hot air balloon 1.5 miles above the ground, convert the height to kilometers and use the formula D = 112.88 km × √h to get the distance to the horizon, which is about 175.4 km. Then, calculate the semicircular distance visible by using C/2 = (π × D) / 2, which results in approximately 276.1 km for the measure of BD⌓.

Explanation:

To calculate the measure of BD⌓, the portion of Earth's surface that is visible from a hot air balloon 1.5 miles above the ground, you can use the formula for the distance to the horizon, given as D = 112.88 km × √h, where h is the height above the Earth's surface. In this case, we must convert the height of 1.5 miles to kilometers before applying the formula, as the formula uses kilometers.

The conversion from miles to kilometers is 1 mile = 1.60934 kilometers, so 1.5 miles is approximately 2.414 km.

Inserting h = 2.414 km into the formula, we get:

D = 112.88 km × √2.414

D = 112.88 km × 1.5535 (approx)

D ≈ 175.4 km (rounded to the nearest tenth)

This is the straight-line distance to the horizon. To find the measure of the arc BD, which is the portion of the Earth's surface visible, we can treat this distance as the radius of a circle and calculate the circumference. However, since we are only looking at the visible part, which is a semicircle, we use half of the circumference C = π × D.

The measure of BD⌓ is therefore approximately:

C/2 = (π × 175.4 km) / 2

C/2 ≈ 276.1 km

Thus, the measure of BD⌓ to the nearest tenth is 276.1 km.

(x − 2) = √(2x + 1) ;

→ "Square" each side of the equation; that is, raised EACH SIDE of the equation to the power of "2" ; to get rid of the "radical" ; as follows:
_______________________________________________

[(x - 2)]² = [ √(2x + 1) ] ² ;

to get:

→ (x - 2)² = (2x - 1) ;

Expand the " (x - 2)² " ;

→ (x - 2)(x -2) = ?

NOTE: (a + b)(c + d) = ac + ad + bd .

→ = (x * x) + (x * -2) + (-2 * x) + (-2 * -2) ;

= (x²) + (-2x) + (-2x) + (4) ;

= x² − 2x − 2x + 4 ;

= x² − 4x + 4 ;
______________________________________________
Now, rewrite the entire question:

→ (x − 2)² = (2x − 1) ;

→ as follows:
______________________________________________

→ " x² − 4x + 4 = 2x − 1 " ;

Now, subtract "2x" from each side of the equation;
& add "1" to each side of the equation:

→ " x² − 4x + 4 − 2x + 1 = 2x − 1 − 2x + 1 " ;

to get:

→ " x² − 6x + 5 = 0 " ; Solve for "x" ;

Let us if : " x² − 6x + 5 " can be factors:

If Tom, George and Mario work together, they can paint a 600 ft2 room in 4 hours. When only George and Mario work together, it takes 8 hours to paint the room. Tom and George, working together, take 6 hours to paint the room. How long would it take Tom to paint the room alone? Hint: Write the system of equations shown below in augmented form, then solve the system for T (Tom's painting rate). Next, use the equation Painted Area = Painting Rate× Time and solve for Time to determine how long it would take Tom to paint the room alone.

4(T+G+M)=600
8(0+G+M)=600
6T+G+0)=600

Answers

We call:

T = Tom's paiting rate [tex]( \frac{ ft^{2} }{h} )[/tex]
G = George's paiting rate [tex]( \frac{ ft^{2} }{h} )[/tex]
M = Mario's paiting rate [tex]( \frac{ ft^{2} }{h} )[/tex]

As the first statement says that they can work together, then:

T + G + M = Painting rate working together, that is the surface area they paint per hour.

Since the problem says that they last four hours painting a [tex] 600ft^{2} [/tex] room, then we need to multiply the amount of hours times the painting rate that is equal the surface area of the room, so:

4(T + G + M) = 600

Applying a similar reasoning, the George and Mario's painting rate is:

0 + G + M
Note that 0 implies that Tom didn't work in this case.

As they last eight hours painting the room, then:

8(0 + G + M) = 600

The same reasoning is applied to Tom and George working together. In this case 0 implies that Mario didn't work, so:

6(T + G + 0) = 600

We have a system of linear equations in three variables T, G, M:

4(T+G+M)=600
8(0+G+M)=600
6(T+G+0)=600

Solving:

(1) T + G + M = 150
(2) G + M = 75
(3) T + G = 100

Substitute (3) in (1):
100 + M = 150 ∴ M = 50

Replace M in (2):
G + 50 = 75 ∴ G = 25

Substitute G in (3)
T + 25 = 100 ∴ T = 75

Then, the painting rates are:
Tom = 75 [tex]( \frac{ ft^{2} }{h} )[/tex]
George = 25 [tex]( \frac{ ft^{2} }{h} )[/tex]
Mario = 50 [tex]( \frac{ ft^{2} }{h} )[/tex]

Solving for Time to determine how long it would take Tom to paint the room alone:

Painted Area = Painting Rate×Time, so:

[tex]Time Tom = \frac{Painted Area}{Painting Rate (T)} [/tex]
[tex]Time Tom = \frac{600}{75} = 8 hours [/tex]

Answer:

A. 8 hours

Question options:

$108.60

$77.01

$66.03

$100.56

Answers

For question 1, We need to calculate the total, find the tax, then add the shipping cost to the total. (70+30+38=138) now we find the tax (138*0.06=8.28) Now we add the tax and cost together and then the shipping and handling and we have our answer (138+8.28+10.75=157.03) So your answer is A.

For question 2, We need to calculate the total and then find the tax. So, we do this: 25.67*3=77.01. Then we add the skirt to the total (77.01+23.55=100.56). Finally, we calculate the tax cost (100.56*0.08=8.0448). So our total is (100.56+8.0448=108.6048) So the answer is A.

The total amount of his order is $157.03.

The total amount of the order is the sum of the items bought, the tax paid an the cost of shipping and handling .

Total cost of the order = cost of the items bought + tax paid + shipping and handling

Total cost of the items bought = cost of jacket + slacks + shirt

$70 + $30 + $38 = $138

Tax paid = 6% x $138 = $8.28

Shipping and handling = $10.75

Total cost = $138 + $8.28 + $10.75 = $157.03

A single 6-sided dice is being rolled. What is the probability of rolling a 5 or an odd number?

Answers

S = sample space
S = set of all possible outcomes
S = {1,2,3,4,5,6}

E = event space
E = set of items we want to happen (rolling a 5, or rolling an odd number)
E = {1, 3, 5}
note: the event of "rolling a 5" is a subset of "rolling an odd number" because 5 is odd

n(S) = number of items in the sample space
n(S) = 6

n(E) = number of items in event space
n(E) = 3

Divide the values to get the probability
P(E) = n(E)/n(S)
P(E) = 3/6
P(E) = 1/2
P(E) = 0.50
P(E) = 50%

The answer in fraction form is 1/2
The answer in decimal form is 0.50
The answer as a percentage is 50%
These three values all represent the same idea, just written in different forms.

note: writing "P(E)" means "the probability of event E occurring", which I've defined as the event space above

Under his "Household expenses" Budget category, Mark has allocated $60 per month for pet food. He can purchase "wet food" for $1.50 per can or "dry food" for $3 per bag.

D.) Name a combination of bags and cabs that will allow him to meet his budget exactly.

Answers

A possible answer to this question is 10 cans of "wet food" and 15 bags of "dry food". 10 cans of wet food make $1.50 * 10 = $15 and 15 bags of dry food make $3.00 * 15 = $45. $45 + $15 = $60.
We can find answers by creating this equation.
$1.50c + $3.00b = $60
where c and b represent the number of "wet food" cans and "dry food" bags, respectively. We can easily substitute numbers and solve for the other quantity that will satisfy the condition of total cost adding up to $60.

Final answer:

The question asked for a combination of wet and dry pet food that meets a monthly budget of $60. One such combination would be buying 10 bags of dry food and 20 cans of wet food, as 3(10) + 1.5(20) equals $60, which fits the budget exactly. There are also other combinations that can fulfill the budget constraint.

Explanation:

The student asked for a combination of bags and cans of pet food that would allow Mark to meet his monthly budget of $60 exactly. With wet food costing $1.50 per can and dry food costing $3.00 per bag, we can create a simple algebraic equation to find multiple combinations. Let's let x represent the number of bags and y represent the number of cans. The equation can be written as 3x + 1.5y = 60.

To find a combination that fits exactly into Mark's budget, consider the following example:

If Mark buys 10 bags of dry food, that would cost 10 × $3 = $30. He would then have $30 left of his budget. At $1.50 per can, he could buy 20 cans of wet food (because 20 × $1.50 = $30). Thus, one possible combination would be 10 bags and 20 cans. The equation for this would be 3(10) + 1.5(20) = 30 + 30 = 60, which satisfies Mark's budget constraint.

It's important to note that there are other combinations that would also meet Mark's budget exactly. The student could experiment with different numbers of bags (x) and cans (y) to find additional combinations. The key is that the total cost must not exceed $60.

The data shows the number of grams of fat found in 9 different health bars.12, 14, 16, 16.5, 11, 18, 18, 14, 20 What is the IQR (interquartile range) for the data?
9
5
16
18

Answers

The interquartile range (IQR) for the given health bar fat content data set is 5 grams, calculated by subtracting the first quartile (13) from the third quartile (18).

To calculate the interquartile range (IQR) of the given health bar data set, first, we must organize the numbers in ascending order: 11, 12, 14, 14, 16, 16.5, 18, 18, 20. The IQR is the difference between the third quartile (Q3) and the first quartile (Q1).

Find the median (the middle value) of the dataset, which will also serve as the second quartile (Q2). The median of the dataset here is 16.

To find Q1, calculate the median of the lower half of the data (not including the median of the dataset if your dataset has an odd number of values). So the lower half of the data is 11, 12, 14, 14, and the median of this is 13.

To find Q3, calculate the median of the upper half of the data. The upper half following our median is 16.5, 18, 18, 20, with a median value of 18.

The IQR is Q3 - Q1, which is 18 - 13 = 5.

Thus, the IQR for the health bars' fat content data is 5 grams.

Hello!

You have to find the probabilities of them happening separately

To do this you do the amount of favorable outcomes over the total amount of outcomes

3 + 2 + 2 + 2 + 5 = 14 total fruit

The chance of Jack getting a peach is 5 / 14

The chance of Bethany getting an orange is 2 / 13 because Jack did not put the fruit back in so their is one less to choose from

You multiply the two probabilities to find the probability of them happening in a row

5/14 * 2/13 = 5/91
