Answer:

The answer is $6216.66

Step-by-step explanation:

(8*40)+6%*×=$692; 320 + 0.6x = 692; .6×=692-320; 0.6x=373; ×=373÷.6;

x=6216.66

Total earnings= $692

Total hours worked = 40 hours

Earnings per hour = $8

Total hourly earnings = Total hours worked × Earnings per hour

= 40 hours × $8

= $320

Commission earnings = Total earnings - Total hourly earnings

= $692 - $320

= $372

Total amount of her sales for the week = x

6% of x = $372

0.06 × x = 372

0.06x = 372

x = 372 / 0.06

x = $6,200

Therefore, her total amount of her sales for the week is $6,200

[tex]Five = 31[/tex]

Step-by-step explanation:

Given

[tex]Total = 142[/tex]

[tex]Even = 56[/tex]

[tex]One = 21[/tex]

[tex]Three = 34[/tex]

Required:

Number of times 5 were rolled

Even represents 2, 4 and 6.

So, we have:

[tex]Total = Even + One + Three + Five[/tex]

[tex]142 = 56 + 21 + 34 + Five[/tex]

[tex]142 = 111 + Five[/tex]

Collect Like Terms

[tex]Five = 142 - 111[/tex]

Answer:

$48.13

Step-by-step explanation:

before $44.98

sale tax 7.00% or 3.15

after-tax price $48.13

========================================================

There are two methods to get the answer.

The slightly longer method is to take 7% of the original price to get

7% of 1350 = (7/100)*1350 = 0.07*1350 = 94.50

The sales tax is $94.50

Add this onto the original price to get 1,350+94.50 = 1,444.50

----------------------------

A shortcut is to multiply the original price by 1.07

The multiplier 1.07 represents a 7% increase since

So we will have 1.07*1350 = 1,444.50

Answer:

$172.5

Step-by-step explanation:

Store A is defintley better because 6% of sales tax is $72 and $1200 + $71 = $1272 while store B: 7% of $1350 is $94.5 and $1350 + $94.5 = $1444.5. To find out how much you would save by using store A, you would simply subtract it =  $1444.50 - $1272 = $172.5

Answer:

1. Yes

2. Yes

3. No

Step-by-step explanation:

Given

Rectangle A:

[tex]Length = 12; Width = 8[/tex]

Rectangle B:

[tex]Length = 15; Width = 10[/tex]

Rectangle C:

[tex]Length = 30; Width = 15[/tex]

Solving (1): Is Rectangle A a scaled copy of Rectangle B?

To do this, we simply determine the ratio of the length and width of both rectangles;

i.e.

[tex]Ratio = \frac{A}{B}[/tex]

For Length:

[tex]Ratio = \frac{12}{15}[/tex]

[tex]Ratio = 0.8[/tex]

For Width:

[tex]Ratio = \frac{8}{10}[/tex]

[tex]Ratio = 0.8[/tex]

Since both ratios are the same, then this statement is true

Solving (2): Is Rectangle B a scaled copy of Rectangle A?

This is the inverse of (1) calculated above.

Since (1) is true, then (2) is also true

3. Is Rectangle A a scaled copy of Rectangle C?

To do this, we simply determine the ratio of the length and width of both rectangles;

i.e.

[tex]Ratio = \frac{A}{C}[/tex]

For Length:

[tex]Ratio = \frac{12}{30}[/tex]

[tex]Ratio = 0.4[/tex]

For Width:

[tex]Ratio = \frac{8}{15}[/tex]

[tex]Ratio = 0.53[/tex]

Since both ratios are the not same, then this statement is false

40

Step-by-step explanation:

Answer:

Step-by-step explanation:

To find the expression for 5/a, you first need to solve the equation 5=a^x for a.  To solve for a, raise both sides of the equation to the 1/x power.  

5=a^x

5^(1/x)=(a^x)^(1/x)              (now multipy exponents)

5^(1/x)=a                           (x*1/x = 1 - the exponent on a)

Now that the equation is solved for a, substitute the left side of the equation into 5/a.  So,

5/a = 5/5^(1/x)             (since the bases are the same, 5, subtract the exponents; note that the exponent in the numerator = 1)

5/a = 5^(1 - 1/x)           (subtract by getting lcd, x)

5/a = 5^((x-1)/x)

Just to show you that this works:  Let a = 25 and x = 1/2.

We know that 5 = a^x = 25^(1/2) = sqrt(25)=5.

Now, 5/a should equal 5/25 = 1/5, so let's plug the numbers into the new expression.

5/a = 5^((.5-1)/.5)   (I'm using .5 instead of 1/2 so it's not so many parentheses.)

Answer:

y=-3x-5

Step-by-step explanation:

2y = -6x-10 (you need to isolate the y and so i took 6x and subtracted it from both sides)

y = -6/2x-10/2 ( dont feel like explaining)

divide them (-6/2 and -10/2) to get

y=-3x-5

What he said lol

Answer with step-by-step explanation:

If the ratio for the ingredients is 1:2:3, then the total would be 6. If so, we have to divide 2.1 by 6, which is 0.35. Now, you need to multiply 0.35 to the according ingredient amounts.

Cement: 1 x 0.35 = 0.35

Sand: 2 x 0.35 = 0.70

Quicklime: 3 x 0.35 = 1.05

If you add it up, you will get 2.1, which is the volume.
