This question is one where the numbers don't add up. You should ask your teacher to show you how to work it.

___

Let n, d, q represent the numbers of nickels, dimes, and quarters Landau has, respectively.

... d = 7n +3 . . . . . the number of dimes is 3 more than 7 times the number of nickels

... q = 2n -4 . . . . . the number of quarters is 4 less than 2 times the number of nickels

... 5n +10d +25q = 330 . . . . the total value of the coins is 330 cents

Using the first two equations to substitute into the last one, we get

... 5n +10(7n +3) +25(2n -4) = 330

... 125n -70 = 330 . . . . . . eliminate parentheses, collect terms

... n = 400/125 . . . . . . . . add 70, divide by 125

... n = 3.2

... d = 7·3.2 +3 = 25.4

... q = 2·3.2 -4 = 2.4

Landau has 3.2 nickels, 25.4 dimes, and 2.4 quarters.

the new price is reduced by 10% of $3000.

10% of $3000 is one tenth of 3000, so 3000/10 = $300

so the original price was reduced by $300 to be $2700

4!(7 – 4)! is equivalent to (4!)(3)!

3! = 3*2*1 = 6, and 4! = 4(6) = 24.

Thus, 4!(7 – 4)! = 24(6) = 144

Answer:

7x+6 = 5(x+6)

Step-by-step explanation:

x represents Harry's age now, so 7x represents Nick's age now. (Nick is 7 times as old as Harry.)

In 6 years, Harry's age will be x+6.

In 6 years, Nick's age will be 7x+6, which is 5 times Harry's age at that time, 5(x+6). Hence an appropriate equation is ...

... 7x+6 = 5(x+6)

_____

Please note that finding the value of x does not give the answer to the question. We are asked for Harry's age in 6 years, so the answer is x+6 (=18).

Answer:

Its D) aka the last option

Step-by-step explanation:

To calculate the interest due after missing a payment, add any late fees to the unpaid bill and apply the monthly interest rate to the outstanding balance. Interest compounds monthly, so it's crucial to pay off the debt quickly to prevent the balance from growing.

To compute the interest due on the next bill after missing a payment for a bill, you need to consider any late fees in addition to the compounded interest. For a credit card company that charges a flat rate of $10 for a late payment and a daily rate of $5 for each day the payment remains unpaid, you would add these fees to the subtotal of the unpaid bill. Additionally, most creditors use a formula to calculate minimum payments and interest on the outstanding balance, typically on a monthly basis.

The interest on the next bill is calculated by multiplying the balance you owe by the interest rate that is applied each month. If you continue to carry a balance from month to month, this interest will be added to your outstanding balance, which will increase the amount you owe. It is important to pay off credit card debt as promptly as possible to avoid accruing additional interest.

Answer:

0.25

Step-by-step explanation:

we have to use the following formula here-

[tex]a^{-m}= \frac{1}{a^{m}}[/tex]

Now, here we get,

[tex]2^{-2}[/tex]

So, applying the formula we get

[tex]2^{-2}= \frac{1}{2^{2}}= \frac{1}{4} =0.25[/tex]

So, the answer is     0.25

[tex]2^{-2}[/tex] = [tex]\frac{1}{4}[/tex]

using the law of exponents

[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{}a^{m}[/tex]

x = -1

Solution :

Given , function[tex]f(x) = 2x+1[/tex]

we have to find the inverse of the function f(x)

Substitute y for f(x):  [tex] y=2x+1[/tex]

Subtract 1 from both sides, [tex]y-1=2x+1-1[/tex]

Divide both sides by 2, [tex]\frac{y-1}{2} = x[/tex]

[tex]\Rightarrow x=\frac{y-1}{2}[/tex]

Substitute [tex]f^{-1}(y)\:for\:x [/tex][tex]\RIghtarrow f^{-1}(y)=\frac{y-1}{2}[/tex]

Hence, The inverse of the function [tex]f(x)=2x+1\:is f^{-1}(y)=\frac{y-1}{2}[/tex]

Answer:

24.75 i just had this question got it wrong but there's the correct answer

This is because the total needs to be equal to 180 degrees. Since obtuse angles are greater than 90 degrees, then it needs an acute angle (lower than 90 degrees) to supplement it to equal 180

3x/6 +1 = 7

Subtract 1 from each side:

3x/6 = 6

Multiply both sides by 6:

3x = 36

Divide both sides by 3:

X = 36 / 3

X = 12

x = 12

given [tex]\frac{3x}{6}[/tex] + 1 = 7 ( subtract 1 from both sides )

[tex]\frac{3x}{6}[/tex] = 6 ( multiply both sides by 6 )

3x = 36 ( divide both sides by 3 )

x = 12

Answer:

110

Step-by-step explanation:

3x + 9y - 18 = 180

3x = 9y - 18

Which means

3x = 90

9y - 18 = 90

Solving for each:

x = 90/ 3

x = 30

And

9y = 108

y = 108/9

y = 12

Answer: x = 30 , y = 12

The values of x and y are 33 and 13, respectively. To find these, we used the properties of a linear pair of angles being equal and supplementary, which led us to a system of equations that we solved for both variables.

When two angles form a linear pair with equal measures, they are supplementary and equal to each other. Therefore, the sum of their measures is 180 degrees. Since both angles in the linear pair are equal, we can set them equal to each other to find the values of x and y.

The first angle is given as 3x degrees and the second angle is given as (9y - 18) degrees. Since they are equal, we can set up the equation:

3x = 9y - 18

To find the value of x and y, we also need to use the fact that angles in a linear pair add up to 180 degrees. Thus:

3x + (9y - 18) = 180

Substituting the value of 3x from the first equation into the second:

3x + 3x = 180 + 18

6x = 198

x = 33

Now substituting the value of x back into the first equation to find the value of y:

3(33) = 9y - 18

99 = 9y - 18

9y = 117

y = 13

The values of x and y are therefore 33 and 13, respectively.

You can write equations for total pay, but in the end, you want to find the amount of sales that makes the difference in commission make up for the difference in base pay.

... (commission rate difference) × sales = (base pay difference)

To find the sales, divide by its coefficient:

... sales = (base pay difference)/(commission rate difference)

Sales = (20,000 -17,000)/(.12 -0.05) = 3000/0.07 ≈ 42,857.14

You need to sell more than $42,857.14 for option A to pay more.

Sales = (25,000 -20,000)/(.09 -.03) = 5000/0.06 ≈ 83,333.33

You need to sell more than $83,333.33 for option A to pay more.

_____

In each case, total pay is ...

... total pay = (base pay) + (commission rate) × sales

For the two options to give the same total pay, the difference in total pay is zero. That occurs when ...

... 0 = (base pay₁) + (commission rate₁) × sales -((base pay₂) + (commission rate₂) × sales)

... 0 = (base pay₁) - (base pay₂) - sales × ((commission rate₁) -(commission rate₂))

Solving for sales, we get the above result:

... sales = ((base pay₂) -(base pay₁))/((commission rate₁) -(commission rate₂))

Solution 8:

We are given base salary of 17000 and 12% of sales.

Les us say salesperson does sales of x amount.

So 12% of x is 0.12x

Total salary = 17000+0.12x

In second case base salary is $20000 and commission of 5% of sales.

Total salay=20000+0.05x

Now for option A to pay more we have:

[tex]17000+0.12x>20000+0.05x[/tex]

Solving we get:

[tex]0.07x>3000[/tex]

x>42,857

Answer: Option A need to make sales of $42,857 more.

Solution 9:

We are given base salary of 20000 and 9% of sales.

Les us say salesperson does sales of x amount.

So 9% of x is 0.09x

Total salary = 20000+0.09x

In second case base salary is $25000 and commission of 3% of sales.

Total salay=25000+0.03x

Now for option A to pay more we have:

[tex]20000+0.09x>25000+0.03x[/tex]

Solving we get:

[tex]0.06x>5000[/tex]

x>83,333.33

Answer: Option A need to make sales of $83,333.33 more.

An angle bisector divides the angle into equal halves.

Given that:

[tex]\angle ABD = 52^o[/tex]

From the question, we understand that:

BC bisects [tex]\angle ABD[/tex]

This means that:

[tex]\angle ABD = 2 \times \angle ABC[/tex] ---- By definition of midpoint

So, we have:

[tex]52^o= 2 \times \angle ABC[/tex] ---- By substitution property

Divide both sides by 2

[tex]26^o= \angle ABC[/tex] ---- By division property of equality

So, we have:

[tex]\angle ABC = 26^o[/tex] --- By symmetric property of equality

Hence,

[tex]\angle ABC = 26^o[/tex] --- proved

Angle D is 180° -75° -45° = 60°. Drawing altitude MX to segment DN divides the triangle into ΔMDX, a 30°-60°-90° triangle, and ΔMNX, a 45°-45°-90° triangle. We know the side ratios of such triangles (shortest-to-longest) are ...

... 30-60-90: 1 : √3 : 2

... 45-45-90: 1 : 1 : √2

The long side of ΔMDX is 10√3, so the other two sides are

... MX = MD(√3/2) = 15

... DX = MD(1/2) = 5√3

The short side of ΔMNX is MX = 15, so the other two sides are

... NX = MX(1) = 15

... MN = MX(√2) = 15√2

Then the perimeter of ΔDMN is ...
