the length of a rectangle is represented by 3x-7 and the width by x+4. express the perimeter as a polynomial in simplest form

**Answer: 8**x - 6

**Step-by-step explanation:**

Perimeter is found by doing 2l + 2w

The length is 3x - 7 and width is x + 4

2(3x - 7) + 2(x + 4) =

6x - 14 + 2x + 8 =

**8x - 6**

**Answer:**

ang 4 = 60°

**Step-by-step explanation:**

ang 1 and ang 4 are Linear pair or supplementary angles.

ang 1 + ang 4 = 180

120° + ang 4 = 180° (Putting the value of ang 1)

ang 4 = 180° - 120°

ang 4 = 60°

Subtract the fractions. Simplify if possible. 3/4 - 1/4 - 2/4 =

This ones really easy. When the denominators are the same, all you have to do is subtract the numerators. So 3-1-2=0. Now put the denominator in: 0/4. But to simplify it, just 0.

determine the 1st term of the first 21 term of an arithmetic series if the sum of the three middle term is 126 and the sum of the three last terms is 288

**Answer:**

- 18

**Step-by-step explanation:**

arithmetic sequences are in form:

a(n)=a(o)+d(n-1)

sum are in form:

s(n)=[a(0)+a(n)](n/2)

three middle terms is:

10th, 11th, 12th term

How to think: 21 = 10+1+10 --> middle 3 is 10,11,12

sum of these 3 terms:

a(10)+a(11)+a(12)

=a(o)+9d+a(0)+10d+a(0)+11d

=3a(0)+30d=126

a(0)+10d=42 ......(equation 1)

Last three terms is:

19th, 20th, 21th

a(19)+a(20)+a(21)

=a(0)+18d+a(0)+19d+a(0)+20d

=3a(0)+57d=288

a(0)+19d=96 ......(equation 2)

now you have

a(0)+10d=42 ......(equation 1)

a(0)+19d=96 ......(equation 2)

solve and gives

d=6

a(0)= -18

The director of a customer service center wants to estimate the mean number of customer calls the center handles each day, so he randomly samples 29 different days and records the number of calls each day. The sample yields a mean of 279.4 calls with a standard deviation of 25.1 calls per day. He can be 99% confident that the mean number of calls per day is between 266.5 and ________. (Round your answer to 1 decimal place.)

**Answer:**

He can be 99% confident that the mean number of calls per day is between 266.5 and **292.3.**

**Step-by-step explanation:**

**Confidence interval:**

A confidence interval is symmetric, which means that the difference between the sample mean and the lower bound is the same as the difference between the upper bound and the sample mean.

**In this question:**

Sample mean: 279.4 calls

Lower bound: 266.5 calls

Upper bound: x calls

**Due to the symmetry of the confidence interval:**

[tex]x - 279.4 = 279.4 - 266.5[/tex]

[tex]x = 12.9 + 279.4[/tex]

[tex]x = 292.3[/tex]

So

He can be 99% confident that the mean number of calls per day is between 266.5 and **292.3.**

Thinking about the table...Why does this

table start at zero? Why aren't there any

negative numbers in the DOMAIN?

**Answer:**

The vertical axis on trending charts should almost always start at zero. The reason it's almost always is because you may have trending data that contains negative values or fractions. In those situations, it's generally best to keep Excel's default scaling.

Why aren't there any negative numbers in the DOMAIN?There are no domain restrictions, even though there is a variable under the radical. Since , can never be negative. The least it can be is , so there is no danger of taking the square root of a negative number.

Find the total surface area of the

following prism:

5 cm

5 cm

5 cm

10 cm

5 cm

apothem = 3.6 cm

SA = [ ? ] cm2

**Answer:**

**Total surface area = 340 cm²**

**Step-by-step explanation:**

Surface area of the given prism = Area of two bases + Area of its lateral surfaces

Area of pentagonal base = [tex]\frac{1}{2}(\text{Apothem)}(\text{Perimeter})[/tex]

= [tex]\frac{1}{2}(3.6)(5\times 5)[/tex]

= 45 cm²

Area of the lateral sides of the prism = Perimeter of the pentagonal base × height

= (5×5)×10

= 250 cm²

**Total surface area of the prism** = 2(45) + 250

= 90 + 250

= **340 cm²**

Y -6 = 2(x+5)

y - 6 + 6 = 2x + 10 + 6

y = 2x + 16

So y = 2x + 16 is your answer

y - 6 + 6 = 2x + 10 + 6

y = 2x + 16

the sumof the present ages of a father and his son is 60 years. 6years ago, the father's age was 5 times the age of his son.after 6 years, how old will the son be?

**Answer:**

20 years

**Step-by-step explanation:**

Let the present ages of son and father be x and (60 -x) years respectively.

Then, (60 - x) - 6 = 5(x - 6)

54 - x = 5x - 30

6x = 84

x = 14.

Son's age after 6 years = (x+ 6) = 20 years..

**Answer:**

No DB is not a perpendicular bisector of AC

**Step-by-step explanation:**

This is because as AC is a straight line it's angle degree is 180 which when bisected by DB becomes,

180 ÷ 2 = 90

On both the angles i.e <BDC = <NDA = 90°

To make it a perpendicular bisector but

<BDC is not equal to <NDA is not equal to 90°.

Hence, DB is not a perpendicular bisector of line AC.

Reflect the figure across the y- axis, then state the ordered pairs of the image.

May someone please explain how I would reflect it?

B’ (3, 2)

R’ (2, -3)

X’ (-2, 0)

Z’ (-2, -2)

EXPLANATION:

Reflecting a figure across the y-axis basically means flipping all of the x-values of your coordinates while retaining its y-value.

In other words, flip the signs of x and keep y the exact same for each coordinate.

B (-3, 2)

Nikki brought a patio set on sale for $480 the original price was 850 what is the rate of discount

**Answer:**

43.5%

**Step-by-step explanation:**

Substitute the original price of $850 and the sale price of $480 to find

amount of discount=850−480=370

Use the amount of discount, $370, to find the discount rate. Use the equation

amount of discount=discount rate×original price.

Rearrange the equation to solve for the unknown value.

discount rate=amount of discountoriginal price

Substitute in the known values and solve to find the discount rate.

370850=0.435=43.5%

Thus, the discount rate on the patio set was 43.5%.

At what rate per annum compound

interest will N4000 amount to N5353

in 5 years?

Answer: Just look it up on goo gle

Step-by-step explanation:

The **rate** per annum **compound** **interest** is approximately 11.5%.

To find the rate per **annum** compound interest, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^{nt}[/tex]

Where:

A = the final amount (N5353 in this case)

P = the **principal amount **(N4000 in this case)

r = the annual interest rate (what we want to find)

n = the number of times interest is compounded per year (assuming once per year)

t = the number of years (5 years in this case)

Now, we can plug in the **values**:

[tex]N5353 = N4000(1 + r/1)^{1*5}[/tex]

Divide both sides by N4000:

[tex]1.33825 = (1 + r)^5[/tex]

Now, isolate (1 + r) by taking the** fifth root **of both sides:

[tex]1 + r = (1.33825)^{1/3}\\1 + r \approx 1.115[/tex]

Now, subtract 1 from both sides to find the interest rate (r):

r ≈ 1.115 - 1

r ≈ 0.115

Finally, convert the interest rate to a **percentage**:

r ≈ 0.115 * 100

r ≈ 11.5%

The angle measurements in the diagram are represented by the following expressions

**Answer:**

∠A is equal to 73°

**Step-by-step explanation:**

Because the two lines that move roughly bottom/left to top/right are marked as being parallel, we can say that ∠A + ∠B = 180°

With that we can take the two equations at the top, and add them together for a sum of 180°:

6x - 35° + 3x + 53° = 180°

9x + 18° = 180°

x + 2° = 20°

x = 18°

Now that we have x, we can solve for ∠A:

∠A = 6x - 35°

∠A = 6(18°) - 35°

∠A = 108° - 35°

∠A = 73°

We can test our answer by solving for ∠B. We know that ∠A and ∠B add up to 180°, so ∠B = 180° - ∠A = (180 - 73)° = 107°. Now let's solve for be given x and the original equation, and see if we have the right numbers:

∠B = 3x + 53°

∠B = 3(18°) + 53°

∠B = 54° + 53°

∠B = 107°

Which matches up, showing us that we have the correct answer.

Please explain in words.
