The ratio of isaiah,s liabilities is less than 1.
Let , isaiah has total debt (not including mortgage) is $7,410.
Her net worth (not including his home) is $21,000.
Therefore, his debt-to-equity ratio is $7,410 divided by $21,000, or 0.35.
therefore, this ratio is less than 1, isaiah has not reached the upper limit of debt obligations.
Your net worth can be calculated by subtracting all of your debts and liabilities from your assets. You may have items that are intangible or difficult to sell that may be excluded from calculations used by financial institutions to determine loan eligibility.
the difference between your assets and your liabilities is your net worth. The formula looks like this: (Sum of the current value of all assets) - (Sum of the current total of all outstanding liabilities) = Net worth.
The net worth of a business is also known as its book value, or as its owners' (stockholders') equity. This figure can be computed relatively easily using information found on a company's balance sheet. However, even if the balance sheet isn't available, you can still calculate a business' net worth if you have some basic financial information.

The toasters produced by a company have a normally distributed life span with a mean of 5.8 years and a standard deviation of 0.9 years, the company is willing to have a warranty that replaces at most 5% of their toasters sold. What is the longest a blender can last and still be in the lowest 5% of life spans?
4.6 years
7.3 years
4.3 years
5.9 years
The longest a blender can last and still be in the lowest 5% of life spans will be 4.6 years. The correct option is A.
What is a normal distribution?The z-score formula can be used to resolve issues with samples that have a normal distribution. The score of a measure X in a collection with mean and standard deviation is given by:
Z = ( X - μ ) / σ
The Z-score calculates the deviation of the measure from the mean in standard deviations. We glance at the z-score table after determining the Z-score to determine the p-value connected to it.
The likelihood that the measure's value is less than X, or the percentile of X, is represented by this p-value. The likelihood that the value of the measure is greater than X is obtained by deducting 1 from the value.
In this problem, we have that:
μ = 5.8, σ = 0.9
Only those on the 5th percentile or lower will be replaced. So the warranty is the value of X when Z has a value of 0.05.
The value of x will be:-
Z = ( X - μ ) / σ
-1.28 = ( X - 5.8 ) / 0.9
X = 4.6
Therefore, the longest a blender can last and still be in the lowest 5% of life spans will be 4.6 years. The correct option is A.

A car and a truck follow the same route on a pair of round-trip deliveries. The function c(x) = -72 ∣ x - 5 | + 360 represents the distance (in miles) of the car from the starting point after x hours. The truck’s distance from the starting point is shown in the graph
Which vehicle takes longer to complete the delivery? How much longer? Justify your answers.
The truck takes a time of 1 longer to complete the delivery than that of the vehicle.
How to interpret Linear Functions?We are given the function that represents the distance (in miles) of the car from the starting point after x hours as;
C(x) = -72|x - 5| + 360
Now, at a time of x = 5 hours, the distance covered by the car is;
C(5) = -72|5 - 5| + 360
C(5) = 0 + 360
C(5) = 360 miles
Thus, the car covers a distance of 360 miles in 5 hours
Now, from the given graph that represents the truck’s distance from the starting point, we see that after 6 hours, it has covered 360 miles. Thus, we say that the truck covers 360 miles in 6 hours.
Thus, the truck takes 1 longer to complete the delivery than that of the vehicle.

What is £105.035 rounded to the nearest whole penny?
Answer:
£105.04
Step-by-step explanation:
To round an amount to the nearest cent, check the value of its thousandths. If the value is equal to 5 or greater, increase the value in the cent’s place by 1 and then remove all digits to the right after the second decimal place. If the value is equal to 4 or less, simply remove all the digits to the right after the second decimal place. For example with £105.035 the thousandths’ value is 5, so we round up: £105.035 --> £105.04

. Mike is putting up a fence in the backyard. The fence comes in sections that are 4 2/3
feet long. If the yard is 34 feet long, how many sections will he need to buy?
Answer:
[tex]7\frac{2}{7}[/tex] sections of fence
Step-by-step explanation:
since we are trying to find how many sections we need and we are given the total length of the yard and the length of each section of the fence, we are going to divide.
you want to divide the 34 yards into the 4 2/3 feet. to make this easier, we can turn 4 [tex]\frac{2}{3}[/tex] into a mixed number. to do this we multiply the 4 by the denominator which is the number on the bottom and add it to the numerator which is the number at the top.
4x3=12
12+2 = 14
[tex]\frac{14}{3}[/tex]
[tex]\frac{34}{1}[/tex] ÷[tex]\frac{14}{3}[/tex]
to divide fractions we multiply by the reciprocal which would be
[tex]\frac{34}{1}[/tex]×[tex]\frac{3}{14}[/tex]
now we just multiply across
34x3= 102
1x14=14
[tex]\frac{102}{14}[/tex]
now the furthest we can simplify this is by dividing the whole thing by 2
51/7
now we turn this back into an improper fraction
we get [tex]7\frac{2}{7}[/tex]
