The height of the ladder far up the wall to the nearest hundredth is 7.52 foot.

A right angle triangle is formed.

A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.

The length of the ladder is the hypotenuse side of the triangle formed.

Therefore,

sin 70 = opposite / 8

cross multiply

opposite = 8 sin 70

opposite side = 8 × 0.93969262078

opposite side = 7.51754096629

opposite side = 7.52

Present age of mom : Present age of son = 6 : 1

Therefore let :

Ages after 10 year :

The ages after 10 years are given in rational of 8 : 3.

Which means :

Step-by-step explanation:

To make such a frequency distribution table, first, write the class intervals in one column. Next, tally the numbers in each category based on the number of times it appears. Finally, write the frequency in the final column. A frequency distribution table drawn above is called a grouped frequency distribution table.

The break-even period after which you could make a $10,000 claim for

property damage without the insurance company suffering a loss is 15 months.

The break-even point is the point at which total revenue is equal to the total cost.

Taking only this customer's premiums, deductible, and claims into account, the break-even time during which the client might submit a $10,000 claim for property damage without causing the insurance company a loss is 15 months.

The corporation will not generate a profit or a loss during this break-even time. Therefore, the following Data and Calculations can be made,

Monthly insurance premium payable = $600 (assumed to be paid monthly)

Deductible on the insurance policy = $1,000

Minimum coverage = 30/50/10

Coverage for injury or death to one person = $30,000

Coverage for injury or death to two or more people = $50,000

Coverage for damage to property = $10,000

Average accidents every year = 2

Total claims cost to the insurance before deductibles = $40,000 ($30,000 + $10,000)

Break-even period = 15($10,000 - $1,000)/$600

This break-even period is calculated by subtracting the deductible from the customer's claim and dividing the result by the monthly insurance cost.

Thus, after a 15-month break-even period, the client might file a $10,000 claim for property damage without the insurance company incurring a loss.

Answer:

C. is the correct answer

Step-by-step explanation:

A. is incorrect because the sequence does not start with 15

B. is incorrect because the pattern increases by 5, not multiplied by 5

C. is correct because all of the even numbers in the pattern do end in 0

D. is incorrect because even numbers don't end in 5's

Hope this helps!

Answer: "Every even-numbered term in the pattern has a 0 in the evens place"

Step-by-step explanation:

     We can compare each statement to the pattern and see which ones don't apply.

   The first one is not true. We are adding 5, not having a sum of previous numbers.

  The second one is not true, it is adding 5. Not 5 times greater.

  An even number is a number ending in 0, 2, 4, 6, or 8. This means

that the third option is correct, giving us our answer.

Answer:

49.36 degrees to the nearest hundredth.

Step-by-step explanation:

In the right angled triangle formed the adjacent side is 25.88 m and the opposite = 30.15 m.

So tan B =  30.15 / 25.88 = 1.16499

So m < B = 49.36 degrees.

A. The word mean is the same as saying average. To find the average/mean add all the numbers together and then divide by the amount of numbers. For example, if your numbers were 2, 6, and 7. You would do 2+6+7=15. Then 15 divided by 3 is 5. The mean of those numbers is 5.

B. The median is the middle number. Put the numbers in a list from least to greatest and then find the one in the middle. For example, if your numbers were 1, 2, 3, 4, 5, 6,  the median would be 3.

C. The mode is the most frequent number. Count how many of each number appears in the list, the one with the most is the mode. For example, if your numbers were 1, 1, 3, 8, 2, 1, the number 1 would be the mode because it appears the most frequently.

D. The range is the smallest number and the largest number. If your numbers were 2, 12, 46, and 9, the range would be 2-46 or 2 to 46.

Answer:

y = 4x - 6

Step-by-step explanation:

Hi there!

We are given the points (3,6) and (1, -2), and that a line passes through these 2 points

We want to find the equation of said line

There are 3 ways to write the equation of the line:

The  most common way is slope-intercept form, so let's write the equation of the line this way

First, we need to find the slope

The slope (m)  can be found using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] & [tex](x_2, y_2)[/tex] are points

Before we calculate, let's label the values of the points.

[tex]x_1=3\\y_1=6\\x_2=1\\y_2=-2[/tex]

Now substitute into the formula

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-2-6}{1-3}[/tex]

Subtract

m=[tex]\frac{-8}{-2}[/tex]

Divide

m= 4

The slope of the line is 4

Substitute 4 as m in y=mx+b:

y = 4x + b

Now to find b

Since the equation passes through both (3,6) and (1, -2), we can use either point to help solve for b.

Taking (3,6) for example:

Substitute 3 as x and 6 as y.

6 = 4(3) + b

Multiply

6 = 12 + b

Subtract 12 from both sides

-6 = b

Substitute -6 as b into the equation

y = 4x - 6

Hope this helps!
