Answer:

Yes

Step-by-step explanation:

Total Price of all 3 items - $34.19

35 > 34.19

Yes, Kiera will have enough to purchase all three items.

No, $35 will not be enough to purchase all three items.

To determine if $35 is enough to purchase all three items, we need to calculate the total cost of the items and compare it to the amount of money Kiera has.

The cost of each item is as follows:

- Mixing bowl: $14.95

- Spatula: $8.49

- Measuring cups: $10.75

Now, let's add up the costs of these items to find the total cost:

Total cost = Cost of mixing bowl + Cost of spatula + Cost of measuring cups

Total cost = $14.95 + $8.49 + $10.75

To make the calculation easier, we can round each price to the nearest whole number:

- Mixing bowl: $14.95 ≈ $15.00

- Spatula: $8.49 ≈ $8.50

- Measuring cups: $10.75 ≈ $10.75 (already a whole number)

Now, let's calculate the total cost with these rounded numbers:

Total cost ≈ $15.00 + $8.50 + $10.75

Total cost ≈ $34.25

However, even with rounding, the total cost is $34.25, which is still less than $35. Therefore, we need to calculate the exact total cost without rounding:

Total cost = $14.95 + $8.49 + $10.75

Total cost = $34.19

Since the total cost of $34.19 is less than $35, it appears that Kiera has enough money to purchase all three items. However, we must also consider sales tax, which is not included in the given prices. Sales tax rates vary by location, but let's assume a standard rate of 7%.

To calculate the total cost including sales tax:

Total cost with tax = Total cost before tax + (Total cost before tax × Sales tax rate)

Total cost with tax = $34.19 + ($34.19 × 0.07)

Total cost with tax = $34.19 + $2.3933

Total cost with tax ≈ $34.19 + $2.40 (rounded to the nearest cent)

Total cost with tax ≈ $36.59

After including the sales tax, the total cost is approximately $36.59, which is more than the $35 Kiera has. Therefore, $35 will not be enough to purchase all three items once sales tax is included.

Answer:

x is less than 6 so that is correct because 24 divided by 4 is 6

Answer:

y + 5 = 3(x + 1) → point-slope form

y = 3x - 2 → slope-intercept form

3x - y = 2 → standard form

Step-by-step explanation:

The point-slope form of an equation of a line:

y - y₁ = m(x - x₁)

m - a slope

(x₁, y₁) - a point on a line

We have

m = 3, (-1, -5) → x₁ = -1, y₁ = -5

Substitute:

y - (-5) = 3(x - (-1))

y + 5 = 3(x + 1) → point-slope form

convert to the slope-intercept form y = mx + b:

y + 5 = 3(x + 1)      use the distributive property: a(b + c) = ab + ac

y + 5 = 3x + 3     subtract 5 from both sides

y = 3x - 2 → slope-intercept form

convert to the standard form Ax + By = C:

y = 3x - 2            subtract 3x from both sides

-3x + y = -2         change the signs

3x - y = 2 → standard form

Answer:

Step-by-step explanation:

       Meghan is soon going to have to spend $78.99 on a dress, $32.50 on shoes, $25 for the ticket and $50 for dinner.

       Meghan already has $52 from her savings to spend. She earns money from babysitting at $12 each hour.

       Let the number of hours Meghan babysits be denoted by [tex]x[/tex].

From [tex]x[/tex] hours of babysitting, Meghan earns $([tex]x\times12[/tex]).

So, her total earnings sum up to [tex]12x+52[/tex]. This should be greater than total spendings.

       [tex]12x+52\geq 78.99+32.50+25+50\\12x\geq 134.49\\x\geq 11.208[/tex]

So, Meghan must work for 12 hours so she has something left after spendings.

∴ Meghan must babysit for 12 hours.

The amount deposited in CD is $660

Given that , To save for the purchase of a new car, a deposit was made into an account that earns 8% annual simple interest.  

Let the amount deposited in new car be $ n

Another deposit, $1700 less than the first deposit, was placed in a certificate of deposit (CD) earning 12% annual simple interest.  

Then, amount deposited in CD will be $ (n – 1700)

The total interest earned on both accounts for 1 year was $676

The simple interest is given as:

[tex]\text { Simple interest }=\frac{\text { principal } \times \text {rate} \times \text {time}}{100}[/tex]

Simple interest for purchase of new car:

[tex]\text { S. } \mathrm{I}=\frac{n \times 8 \times 1}{100}=\frac{8 n}{100}[/tex]

Simple interest for CD:

[tex]\text { S.I } =\frac{(n-1700) \times 12 \times 1}{100}=\frac{12(n-1700)}{100}[/tex]

Now, given that S.I for new car + S.I for CD = 676

[tex]\begin{array}{l}{\frac{8 n}{100}+\frac{12(n-1700)}{100}=676} \\\\ {\frac{8 n+12 n-12 \times 1700}{100}=676}\end{array}[/tex]

20n = 67600 – 20400

n = 2360

So money deposited in CD = n - 1700 = 2360 – 1700 = 660

Hence, the CD deposit amount is $660

To find the amount deposited in the CD, set up an equation using the given information. Solve for x to find the amount of the first deposit. Subtract $1700 from the first deposit to find the amount deposited in the CD.

To find the amount of money deposited in the CD, we can set up an equation using the given information.

Let the amount of the first deposit be x.

The second deposit is $1700 less than the first deposit, so it is x - $1700.

Using the formula for simple interest, the interest earned on the first deposit is x * 0.08.

The interest earned on the second deposit is (x - $1700) * 0.12.

According to the given information, the total interest earned is $676. Therefore, we can set up the equation: x * 0.08 + (x - $1700) * 0.12 = $676.

Simplifying and solving for x:

0.08x + 0.12x - $204 = $676

0.20x - $204 = $676

0.20x = $880

x = $4400

Therefore, the amount of money deposited in the CD is $4400 - $1700 = $2700.

Answer:

The total amount of money Alex spends on 5 DVD = $ 35.

Step-by-step explanation:

Total number of DVD purchased by Alex = 5

The cost of each DVD = $9

So, the total cost of purchasing 5 DVD = 5 x ( csot of 1 DVD)

= 5 x ( $ 9) = $ 45

Now , the discount if 1 DVD = $ 2

So, the total discount of 5 DVD = 5 x ( Discount on1 DVD)

= 5 x ($ 2) = $ 10

⇒ The total amount Alex spends

= Total cost of 5 DVD - Discount on 5 DVD

= $ 45 - $ 10 = $ 35

Hence, the total amount of money Alex spends on 5 DVD = $ 35.

Answer:

The labor cost per shirt of the American factory is 0.36 times the labor cost per shirt of the foreign company.

Step-by-step explanation:

A textile factory in the United States plays 300 workers a total of $9 million each year to produce 4.5 million shirts.

Therefore, the labor cost per shirt will be

[tex]\frac{9 \times 10^{6}}{300 \times 4.5 \times 10^{6}} = 0.0067[/tex]

Again, a foreign factory employs 225 workers at a total cost of $1,050,000 to produce 2,500,00 shirts.

Therefore, the labor cost per shirt will be

[tex]\frac{1050000}{250000 \times 225} = 0.01867[/tex]

Therefore, the labor cost per shirt of the American factory is 0.36 times (Approximate) the labor cost per shirt of the foreign company. (Answer)

 Answer:

Number of Adult's tickets sold on Saturday = 3,356

Number of Children's tickets sold on Saturday = 2, 928

Total number of tickets sold over these two days is 8,938.

Step-by-step explanation:

Here, the number of tickets sold on FRIDAY:

Adult Ticket sold = 1,678

Children's Tickets sold = 976

So, the total number of tickets sold on Friday  

= Sum of ( Adult + Children's ) tickets  = 1,678  + 976 = 2,654 ....  (1)

The number of tickets sold on SATURDAY:

Adult Ticket sold =   2 times  the number of adult tickets sold on Friday  

                             =  1,678 x 2  = 3,356

Children's Tickets sold = 3 x the number of children's tickets sold on Friday.

                                      =  976  x 3 = 2, 928

So, the total number of tickets sold on Saturday  

= Sum of ( Adult + Children's ) tickets  = 3,356 + 2,928 = 6, 284 ....  (2)

Now, the total number of tickets booked in these two days :

Sum of tickets booked on (Friday + Saturday)

= 2,654 +  6, 284  =   8,938

Hence, total number of tickets sold over these two days is 8,938

The relation to find base is, [tex]base=\frac{area\ of\ the \ parallelogram}{height}=\frac{86}{12}=7.16\ cm[/tex]

Step-by-step explanation:

Given

Area of the parallelogram [tex]=86\ cm^2[/tex]

Height of the parallelogram [tex]=12\ cm[/tex]

We know that the area of the parallelogram [tex]=base\times height[/tex]

So

To find base we have to divide the height on both sides of the equation.

The new copier can create 2000 copies in 20 minutes.

Step-by-step explanation:

Given,

It takes 60 minutes to make 2000 copies by old printer and 15 minutes to made x number of copies, therefore, using proportion

[tex]60:2000::15:x[/tex]

Product of mean = Product of extreme

[tex]2000*15=60*x\\30000=60x\\60x=30000[/tex]

Dividing both sides by 60

[tex]\frac{60x}{60}=\frac{30000}{60}\\x=500[/tex]

As the new copier is working with old copier, therefore,

Copies made by new printer = 2000 - 500 = 1500

New copier can make 1500 copies in 15 minutes and 2000 copies in x minutes, using proportion

[tex]1500:15::2000:x\\1500*x=15*2000\\1500x=30000[/tex]

Dividing both sides by 1500;

[tex]\frac{1500x}{1500}=\frac{30000}{1500}\\x=20[/tex]

The new copier can create 2000 copies in 20 minutes.

I think it's false.... 5/6 is 83.33% as a percent so I don't think it's true.

6/6 ......... 100%

5/6 ..............x%

x = 5/6*100/6/6 = 500/6 = 83,(3)%

So if you're asked to graph a function and its inverse, all you have to do is graph the function and then switch all x and y values in each point to graph the inverse. Just look at all those values switching places from the f(x) function to its inverse g(x) (and back again), reflected over the line y = x.

The equation of the line across which all inverses reflect is y = x. This reflection principle applies to linear functions, hyperbolas, and other mathematical relations where inverses can be found by interchanging the roles of x and y.

The equation of the line that all inverses reflect across is y = x. This is because when you are finding the inverse of a function, you swap the x and y variables, thus mirroring the original function across the line y = x. If you have a linear function in the slope-intercept form (y = mx + b), and you find its inverse, assuming the function is one-to-one and therefore has an inverse, you would essentially swap the x and y coordinates, resulting in the equation of its inverse. This process reflects each point of the original function across the line y = x.

As an example, for a line with an equation y = -x + 1, the inverse when reflected across the line y = x would result in swapping x and y to get x = -y + 1, which when solved for y, gives the inverse function's equation. Conversely, for a function expressed in another form, such as a hyperbola or a set of simultaneous linear equations, the principle is the same: to find the inverse, interchange the roles of the dependent and independent variables. For instance, a hyperbola described by y = a - b/x could have its inverse derived by interchanging x and y, leading to the inverse relation x = a - b/y.

Answer:

42 years, 9 months

Step-by-step explanation:

Using the compound interest formula Accrued Amount = P (1 + r/n)^(nt)

where Accrued amount (A) which is quadruple the initial deposit

A = 4 x 500 = $2000

P = principal; $500

r = 3.25% = 0.0325

t = number of years

n = number of times interest is compounded = 12 for monthly

Therefore

2000 = 500 (1 + 0.0325/12)^(12t)

Therefore

(1.002708)^12t = 2000/500

(1.002708)^12t = 4

finding the log of both sides

12t x log 1.002708 = log 4

12t x 0.001174 = 0.6021

12t = 0.6021/0.001174

12t = 512.83

t = 512.83/12

t = 42.7

which is estimated as 42 years, (0.7 x 12 = 9) months

hence it takes about 43 years to quadruple the deposit

The number of years it will take to be the amount by quadruple will be 42.7 years.

Compound interest is applicable when there will be a change in the principal amount after the given time period.

As per the given,

The total amount will be,

A = 4 × 500 = $2000

Principle amount P = $500
Rate of interest r =  3.25% = 0.0325

The time period is t.

n = number of times interest is compounded

n = 12

By compound interest formula,

2000 = 500 [tex](1 + 0.0325/12)^{12t}[/tex]

(1.002708)^12t = 2000/500

(1.002708)^12t = 4

Take logs on both sides,

12t × log 1.002708 = log 4

12t × 0.001174 = 0.6021

12t = 0.6021/0.001174

12t = 512.83

t = 512.83/12

t = 42.7

Thus, the time period will be 42.7 years.

Hence "The number of years it will take to be the amount by quadruple will be 42.7 years.".

Answer:

Total pay for the week is $924.

Step-by-step explanation:

The per hour rate of weekdays from Monday to Friday =  $15.40

The rate for Saturday = One and Half ( $15.40)

Now,  [tex]1\frac{1}{2}  \times (15.40)  = \frac{3}{2} (15.40) = 23.1[/tex]

So, the per hourly rate for work on Saturday  = $23.1

The rate for Sunday  = 2 x ( $15.40)  = $30.80

So, the per hourly rate for work on Sunday  = $30.80

Now, total hours worked in weekday = 38

So, the rate of 38 hours = 38 x ( Per hour rate) = 38 x ($15.40)  

                                        = $585.2

Now, total hours worked on Saturday  = 8

So, the rate of 8 hours = 8 x ( Per hour rate) = 8 x ($23.1)    = $184.8

Now, total hours worked on Sunday  = 5

So, the rate of 5 hours = 5 x ( Per hour rate) = 5 x ($30.80)    = $154

Hence the total pay = Payment of ( weekday  + Saturday +Sunday)

= $585.2 +  $184.8 +  $154  =  $924

Hence, total pay for the week is $924.

Answer:

When the denominator is an irrational number in order to make the denominator a rational number we rationalize the denominator.

Step-by-step explanation:

For example,

[tex]\frac{1}{1+\sqrt{2} }[/tex] (here the denominator is an irrational number)

Multiply the numerator and denominator by [tex]1-\sqrt{2}[/tex]

We get [tex]\frac{1-\sqrt{2} }{(1+\sqrt{2})(1-\sqrt{2}) }[/tex]

Here (1+\sqrt{2})(1-\sqrt{2}) = -1

Thus we get [tex]\sqrt{2} -1[/tex]

Here the denominator has become a rational number.

When we are isolating a variable we are only taking the required variables to one side thus it doesn't require rationalization.

[tex]a = \frac{x}{1+\sqrt{2} }[/tex]

Then we can say,

[tex]x = a(1+\sqrt{2})[/tex]

No rationalisation required
