tinku is fond of collecting spiders and insects. He knows spiders have 8 legs and insects have 6 legs. he counted 36 legs. How many of each does he have in hi collection?

Answers

Answer 1

Let, number of spiders = x
number of insects = y

6x + 8y = 36

remember, legs can't be in fraction or decimal.

So, only (3, 2) fits with that.

So, there are 3 spiders & 2 insects in his collection.

So the number 72 is between the PRODUCT of two perfect squares such as those.

One product has to be above 72, and the other below it.

So lets multiply.

8 x 8 = 64
9 x 9 = 81

Oh look at that, 72 is between 64 and 81.

64=8^2

Your poor health causes you to miss one work day every two weeks. You do not get paid when you are out sick. You normally work 8 hours a day and get paid $9.29 per hour. How much pay are you losing each year

Answers

Final answer:

The annual loss of income due to missing one work day every two weeks at $9.29 per hour, working 8 hours per missed day, is $1,932.32.

Explanation:

To calculate the amount of pay being lost each year due to missing one work day every two weeks, we need to consider the weekly work schedule and hourly wage.

Step-by-Step Calculation

First, determine the hourly wage and the number of hours missed per day. In this case, the hourly wage is $9.29 and each missed day accounts for 8 hours of work.
Second, calculate the daily loss of income due to illness. Multiply the hourly wage by the number of hours missed: $9.29 x 8 = $74.32.
Third, calculate how many work days are missed per year. Since one work day is missed every two weeks, and there are 52 weeks in a year, there would be a total of 52 / 2 = 26 missed work days per year.
Finally, multiply the daily loss of income by the number of missed work days per year to find the annual loss: $74.32 x 26 = $1,932.32.

The annual loss of income due to missing one day of work every two weeks at an hourly wage of $9.29 is $1,932.32.

The sales tax rate in jans town is 7.5.if she buys 3 lamps for $23.59 each and a sofa for $769.99 , how much sales tax does she own ?

Answers

I believe that tax rate are in percent, so tax rate = 7.5%

Now, lets we total the money that she must pay without tax ( just for 3 lamps and 1 sofa ) :
3 lamps = 3 . $23.59 = $70.77
1 sofa = $ 769.99
Total amount = $769.99 + $70.77 = $840.76

We have to find tax amount, the tax amount of the total amount is about 7.5% of the price. Then we have to adding the tax amount into the total amount. So that we have the Total amount including the tax.

tax amount = 7.5% . 840.76 = $63.057
Total amount (inc. tax amount) =
$840.76 + $63.057 = $903.817

Therefore, she must pay those sofa and lamps about $903.817. So expensive huh? =))

Answers

Q5. The answer is $474.

Discretionary income = Net income - Total Expenses
Total Expenses = $2,376.00
Net income = $2,850.00

Discretionary income = $2,850.00 - $2,376.00 = $474

Q8. The answer is 83.47% (over 75% of the circle).

Total Expenses = Housing + Insurance + Food + Utilities + Miscellaneous + Transportation + Clothing + Medical + Savings

Total Expenses = $500.00 + $283.00 + $225.00 + $174.00 + $75.00 + $64.00 + $50.00 + $25.00 + $20.00 = $1416

Total of housing, utilities, food, and insurance is: $500.00 + $174.00 + $225.00 + $283.00 = $1182

Calculate the percent of $1182 in $1416:
$1182 : $1416 * 100 = 83.47%

find two consecutive odd integers whose sum is -88

Answers

Instead of guessing (guess and check) or me giving you the answer, lets solve this mathematically.

first number is x. Second number is the next (or consecutive) odd number so its x+2 (can also do x-2)

Using (x+2)
x + (x+2) = -88
2x = -90
x = -45
and the other number will be -43

Using (x=2)
x + (x-2) = -88
2x = -86
x = -43
and the other number will be -45

The answer: -45, -43.
______________________
Explanation:
_________________________________
Let "x" = one of the odd integers.

Let "x + 2" = the other odd integer.
_________________________________
x + (x + 2) = - 88 ;

x + x + 2 = - 88;

2x + 2 = - 88 ; Now, subtract "2" from EACH side of the equation:
_______________________
2x + 2 - 2 = - 88 - 2 ; to get:
______________________________
2x = -90 ; Now, divide EACH side of the equation by "2"; to isolate "x" on one side of the question; and solve for "x";

If 3x-1=11, then 2x=?

Answers

Final answer:

To find 2x, we first need to solve for x in the equation 3x - 1 = 11. We isolate x by adding 1 to both sides and divide by 3 to obtain x = 4. Finally, multiplying x by 2 gives us 2x = 8.

Explanation:

To solve the equation 3x - 1 = 11 for 2x, we need to isolate x first. Adding 1 to both sides, we get 3x = 12. Dividing both sides by 3, we find that x = 4. Now, to find 2x, we simply multiply x by 2, which gives us 2(4) = 8.

A, 4, D, H, 16, M, 25, _, _ What are the next two in the sequence?

Answers

I would say that the new two in sequence are S and 36.
There are two numbers between A and D, three between D and H, four between H and M, which means that S is the fifth number after M.
I think you are missing number 9 between D and H, which means that 4 + 5 =9, 9 + 7 = 16, 16 + 9 = 25, and 25 + 11 = 36, 2 is added to each number.

The sequence alternates between letters and squares of integers. The letters seem to follow a particular positional increment pattern, and the numbers are squares of consecutive positive integers. The missing elements in the sequence are R and 36.

The given sequence is: A, 4, D, H, 16, M, 25, _, _. This sequence appears to have two separate patterns interleaved. One pattern is a sequence of letters and the other is a sequence of numbers. For the letters part, A (1st letter), D (4th letter), H (8th letter), M (13th letter), so the next letters might follow an increasing pattern with the position of the letters in the alphabet. For the numbers, we have 4, 16, 25 which are squares of 2, 4, and 5 respectively. To solve for the next elements in the pattern, we would have to decipher the rule that connects the letters with their positions and the next squares of numbers.

The numbers are squares of consecutive positive integers: 2², 4², 5². The next number is 6² which is 36. Following the pattern in letters, after M (the 13th letter), the next letter should be the letter that is five positions ahead because the interval between the previous letters increased by 3 each time (D is 3 letters after A, H is 4 letters after D, M is 5 letters after H), so the next letter should be R (the 18th letter, which is 5 letters after M).

Therefore, the sequence should continue with R, 36.

We have to find the length of diagonal.

We know In rectangle diagonal are of equal lengths.

Therefore, for rectangle ABCD diagonals AC= BD

Substitute the values, we get,

[tex]\frac{3y}{5}=3y-4[/tex]

Cross multiply , we get

[tex]3y=5(3y-4)[/tex]

On simplyfy , we get

[tex]3y=15y-20[/tex]

Solve for y , we get

[tex]12y=20[/tex]

Divide both side by 12, we get,

[tex]y=\frac{20}{12}=\frac{10}{6}[/tex]

Thus, put the values of y in AC and BD to find the length of diagonals , we get,

7 / 35 = ? / 28

Answers

Final answer:

To find the missing number in the proportion 7 / 35 = ? / 28, we can use the concept of cross-multiplication. The missing number is 5.6.

Explanation:

To find the missing number in the proportion 7 / 35 = ? / 28, we can use the concept of cross-multiplication. Cross-multiplication involves multiplying the numerator of one fraction by the denominator of the other fraction, and then setting the two products equal to each other. In this case, we have 7 * 28 = ? * 35. Solving for the missing number, we get:

7 * 28 = ? * 35
196 = ? * 35
? = 196 / 35
? = 5.6

So, the missing number is 5.6.

Which function has the greatest y-intercept? (2 points)

f(x)

g(x)

h(x)

All three functions have the same y-intercept.

Answers

Final answer:

The function h(x) has the greatest y-intercept of 8, as it crosses the y-axis at the highest point.

Explanation:

The function that has the greatest y-intercept is the one that crosses the y-axis at the highest value. The y-intercept is the point where the graph of a function intersects the y-axis, which is when x = 0. So, to find the function with the greatest y-intercept, we need to evaluate the y-value when x = 0 for each function.

Let's consider the functions f(x), g(x), and h(x). If f(x) has an equation of y = 3x + 5, g(x) has an equation of y = x - 2, and h(x) has an equation of y = -2x + 8, we can plug in x = 0 and see which function gives us the greatest y-value.

For f(x), when x = 0, y = 3(0) + 5 = 5. For g(x), when x = 0, y = 0 - 2 = -2. And for h(x), when x = 0, y = -2(0) + 8 = 8. Thus, h(x) has the greatest y-intercept because it crosses the y-axis at the highest point, which is 8.
