Answer:  A=50.2

Step-by-step explanation:

using 3.14 as pie...

A=3.14[tex]r^{2}[/tex]

A=3.14x[tex]4^{2}[/tex]

A=3.14x16

A=50.24

Answer:

a) f(-6) = 37

b) f(8) = 65

Step-by-step explanation:

Answer:

4x^4-12x^3+16x^2

Step-by-step explanation:

(-4x+4)(x^3+4x^2)

a      b    c      d

using foil method multiply

term a by term c and d

-4x * x^3= -4x^4

-4x * 4x^2= -16x^3

*dont forget to add the exponents, when x is by itself you it always has an imaginary 1

then multiply term b by term c and d

4 * x^3= 4x^3

4 * 4x^2= 16x^2

line up all of your answers from biggest exponent to smallest

-4x^4-16x^3+4x^3+16x^2

we can combine like terms with -16x^3 and 4x^3 becaus ethey have the same exponent value

4x^4-12x^3+16x^2

Answer:

$125.42

Step-by-step explanation:

Her grandparents will cover 65% of $8600, which is 8600 * 0.65 = $5590. Therefore, she needs to pay for the part they're not covering, which is $8600 - $5590 = $3010.

2 years = 24 months, so assuming she wants to save the same amount each month, we need to divide $3010 by 24 to get the amount per month. This gets us $125.42

The minimum amount that she should save each month for two years is $125.42.

Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.

Amount given by her grandparents = 65% x 8600= $5590

Amount she would have to save each month for two years = (8600 - $5590) / 24 = $125.42

probability of green marble=?

green marbles are 5 so,

       Probability=number of favourable outcomes / number of all possible outcomes

   total outcomes=20

green ball chances=5

       =5/20

          =1/4

Answer:

she bought 4 large frames and 14 small frames!

Step-by-step explanation:

This is a system of equation problem!

let's say that x= large frames and y=small frames.

since there's 18 total, we already have our first equation set.

x+y=18

(number of large frames) + (number of small frames)= 18

13x would represent the large frames because each one is 13 dollars.

6y would represent the small frames because each one is 6 dollars.

Since she paid 136 dollars total, we can already tell that

13x+6y=136

(price of large frames*number of large frames) + (price of small frames*number of small frames)=136.

Now, time for the math!

Attached below is how you would work it out using substitution.

Hope this helps!

x=4 and y=14

Meaning that she bought 4 large frames and 14 small frames!

Answer:

136 cm²

Step-by-step explanation:

Area of the composite figure = area of the triangle + area of the rectangle

= ½*bh + L*W

Where,

b = 16 - 8 = 8 cm

h = 13 - 7 = 6 cm

L = 16 cm

W = 7 cm

Plug in the values into the equation

Area of the composite figure = ½*8*6 + 16*7

= 24 + 112

= 136 cm²

Answer:

Step-by-step explanation:

Meal cost=$15.75

tip=15%

   =  (15*15.75) /100

=236.25/100

  =2.235$=2.24 will give as tip

Cost of shoes=80$

Discount=50%

coupon discount=10%

Total discount=50%+10%=60%

Final price of shoes=?

( 60*80)/100

4800/100

48

60% of 80 is 48 .

pricec  that lyia paid=total price-dicount

         =80-48

         =32$

Xbox=$350

NBA=$45

total=395$

sales tax=8%

(8*395)/100

3160/100

31.6=31.60$

For total price=31.60+395=426.6$

Answer:

1.) $2.36  

2.) $36

3.) a) $31.60

3.) b) $426.60

Step-by-step explanation:

1.) To begin we need to convert 15% to a decimal. To do this we can move the decimal point 2 spaces to the left. This gives us 15% -> 0.15

Then we multiply this number (0.15) by the total mean cost.

15.75 · 0.15 = 2.36

This means that a 15% tip on a $15.75 meal would add $2.36 to the total cost.

2.) To begin we need to find what 50% of 80 is. This is simple because 50% is half of the original price. We can also move the decimal place over 2 numbers to the left to get 0.50 and multiply this by the original price.

80 · 0.50 = 40         OR...        80 ÷ 2 = 40

Now the problems says that Lyla has an extra 10% off from that discounted price that we just figured out (40). We move the decimal place 2 numbers to the left again and multiply by 40.

40 · 0.10 = 4

Finally we subtract our 10% discount (which is $4) from our new original price ($40).      

40-4 = 36

3.) a.) 350 + 45 = $395 ( this is the price of both items before tax).

To find the extra cost of the 8% tax we move the decimal over to the left 2 places. 8% -> 0.08

We can then multiply of cost and tax.

395 · 0.08 = 31.60 (this means that there is a $31.60 tax on this purchase).

3.) b.) For the total price we add the tax we just found and the original cost of the 2 items.

$31.60 + $395 = $426.60

Step-by-step explanation:

Answer:

The store owner must use 18 pounds of the 45 ¢ pasta.

Step-by-step explanation:

Given that a store owner has 12 pounds of pasta worth 70 ¢ a pound, and she wants to mix it with pasta worth 45 ¢ a pound so that the total mixture can be sold for 55 ¢ a pound, to determine how much of the 45 ¢ pasta must she use, the following calculation must be performed:

100 x 0.7 + 0 x 0.45 = 70

90 x 0.7 + 10 x 0.45 = 67.5

50 x 0.7 + 50 x 0.45 = 57.5

40 x 0.7 + 60 x 0.45 = 55

40 = 12

60 = X

60 x 12/40 = X

720/40 = X

18 = X

Thus, the store owner must use 18 pounds of the 45 ¢ pasta.

Answer: 19/21

Step-by-step explanation: find the same multiple for both so you can combine them

Answer:

Step-by-step explanation:

On the left side of the chart, is the x values. The x values are listed on the x axis which is the horizontal line.

The right side of the chart are the y values. The y values are listed on the y axis which is the vertical line.

Knowing this, we can start

First, for all the answer that we know the x value, we need to find the number that matches on the x axis. Once we find that number, we go up or down on the y axis until we find the line.

If we know the y value, we need to find the number that matches on the y axis. Then we will go right until we find the line.

Remember - There CAN NOT be two y values for the same x value but THERE CAN BE two x values for the same y value

Answer:

Part a [5522.3511 ; 5727.8488]

Part b. The p-value is 0.050115.

The H0 is rejected and concluded that the true mean life of a biomedical device is greater than 5500.

Step-by-step explanation:

The 95 % confidence interval for the mean of the population is given by

∝= 1- 0.95= 0.05

υ= n-1= 15-1= 14

x`± t ∝() s / √n

5625.1 ± { t (0.05) (14)} 226.1 / √15

5625.1 ± 1.76 * 226.1/3.8729

5625.1 ± 102.7488

[5522.3511 ; 5727.8488]

Part b

State the null and the alternate hypothesis

H0: u= 5500  against the claim Ha: u > 5500

the test statistic

t= x`- u/ s/ √n

t= 5625.1-5500/226.1 / √15

t=2.143

The p-value is 0.050115.

The result is not significant at p < 0.05.

The H0 is rejected and concluded that the true mean life of a biomedical device is greater than 5500.
