On average, the post office processes 45.6 letters every hour. How many letters can the office process during the 9 hours it is open? 410.4 4104 405 None of the above During Christmas, the post office opens 12 hours a day. Compared to usual days (9 hours), how many more letters can the post office process? 410.4 136.8 547.2 None of the above

Answers

Answer 1

Answer:

410.4

136.8

Step-by-step explanation:

Because the post office processes 45.6 letters every hour and is open 9 days an hour, it processes 45.6*9, or 410.4 letters per day.  Because it is open on Christmas for 3 hours more than normal days(12-9), it produces 45.6*3, or 136.8 more letters on Christmas.

Hope it helps <3

Answer 2

Answer:

A. 410.4 letters

B. 136.8 more letters

Step-by-step explanation:

1.

We know that the post office processes 45.6 letters per hour. If we want to know how many letters they process in 9 hours, we can multiply 45.6 and 9.

45.6 * 9

Multiply

410.4

The post office can process 410.4 letters in 9 hours, therefore A is correct.

2.

The post office still process 45.6 letters per hour, but they are open for 12 hours. First, multiply 12 and 45.6.

12 * 45.6

547.2

We are asked to find how many more letters they can process. We need to find the difference between the letters they normally process and the letters they process on Christmas.

Christmas - normal

They process 547.2 on Christmas and 410.4 normally.

547.2 - 410.4

136.8

They process 136.8 more letters on Christmas. Therefore, choice B is correct. Thank

The sum of ages Afful and Naomi is 34. In 5 years time , Afful will be 2 times the age on Naomi now. How old are they now.

Answers

Answer:

Afful is 21 and Naomi is 13.

Step-by-step explanation:

Let [tex]A[/tex] represent the age of Afful and [tex]N[/tex] represent the age of Naomi.

The sum of their ages is 34. In other words:

[tex]A+N=34[/tex]

In 5 years time, Afful will be two times the age of Naomi now. In other words:

[tex]A+5=2N[/tex]

Therefore, we have that each member made or selected only on vaction option which gives;

The number of members that prefer a beach vacation and a ski vacation are;

Sample A  = 5 + 19 = 24 members

Sample B =  6 + 21 = 27 members

The number of members that prefer an adventure vacation are;

Sample A  = 6 members

Sample B =  1 members

Which shows that more people prefer a beach vacation and a ski vacation than an adventure vacation.

To find Angle A we use cosine

cos ∅ = adjacent / hypotenuse

From the question

The adjacent is 17

The hypotenuse is 38

So we have

cos A = 17/38

A = cos-¹ 17/38

A = 63.4

A = 63° to the nearest degree

To find Angle C we use sine

sin ∅ = opposite / hypotenuse

From the question

The opposite is 17

The hypotenuse is 38

So we have

sin C = 17/38

C = sin-¹ 17/38

C = 26.57

C = 27° to the nearest degree

The perimeter of a rectangle is 60 cm. The ratio of length to width is 3:2. Find the length and width of the rectangle.

Answers

Answer: L = 18 and W = 12

Explanation:

Find the semi rectangle:

60/2 = 30

Now we can find the length and width using the semi rectangle:

L = 30 x 3/5 = 18

W = 30 x 2/5 = 12

Answer:

See below.

Step-by-step explanation:

The perimeter = 2*length + 2 * width.

As the ratio is 3:2 the fraction 3 / (3 +2)  is used to find the length:

The measure of the 2 lengths = 3/ (3+2)  * 60

= 3/5 * 60

= 36 cm

So the measure of the length = 18 cm

So the measure of  the width = (60 - 36) / 2

= 24/2

= 12 cm.

Any time you have compounding more than once a year (which is annually), unless we are talking about compounding continuously, you will use the formula

The interest rate in decimal form is .18; that's r.

The number of times the interest compounds is 12; that's n

Filling all that into the formula:

[tex]4672.12=P(1+\frac{.18}{12})^{(12)(3.5)}[/tex] Simplifying it down a bit:

The surface area of a solid is 10 square feet. The dimensions of a similar solid are

is...
PLEASE urgent

Answers

Answer:

90 ft²

Step-by-step explanation:

Given the sides of similar figures in the ratio a : b, then

ratio of areas = a² : b²

Here ratio of sides = 1 : 3 , thus

ratio of areas = 1² : 3² = 1 : 9

That is the surface area of the new solid is 9 times the first

SA = 9 × 10 = 90 ft²

The total surface area of the new solid in square feet is 90 square feet

Let the solid be a cube.

The surface area of a cube = 6L²

L is the length o the cube;

If the surface area of a solid is 10 square feet, then;

10 = 6L²

L² = 10/6

L = √10/6

If the dimensions of a similar solid are  three times as great as the first, then;

New length Ln = 3√10/6

Total surface area of the new solid = 6Ln²

Total surface area of the new solid = 6(3√10/6)²

Total surface area of the new solid = 6(9*10/6)

Total surface area of the new solid = 6(90/6)

Total surface area of the new solid = 90 square feet

This shows that the total surface area of the new solid in square feet is 90 square feet

if the vertex of a parabola is (-4,6) and another point on the curve is (-3,14), what is the coefficient of the squared expression in the parabola's equation?

Answers

Answer:

8

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (- 4, 6 ), thus

y = a(x + 4)² + 6

To find a substitute (- 3, 14) into the equation

14 = a(- 3 + 4)² + 6 ( subtract 6 from both sides )

8 = a

The closure property describes cases when mathematical operations are CLOSED. It means that if you apply certain mathematical operations in a polynomial it will still be a polynomial. Polynomials are closed for sum, subtraction, and multiplication.

It means:

[tex]\text{Sum of polynomials } \Rightarrow \text{ It will always be a polynomial}[/tex]  

[tex]\text{Subtraction of polynomials } \Rightarrow \text{ It will always be a polynomial}[/tex]  

[tex]\text{Multiplication of polynomials } \Rightarrow \text{ It will always be a polynomial}[/tex]  

But when it is about division:

[tex]\text{Division of polynomials } \Rightarrow \text{ It will not always/sometimes be a polynomial}[/tex]  

Example of subtraction of polynomials:

[tex](2x^2+2x+3) - (x^2+5x+2)[/tex]

[tex]x^2-3x+1[/tex]

Step-by-step explanation:

First, it is very important to define what is a polynomial in standard form:

It is when the terms are ordered from the highest degree to the lowest degree.

Therefore I can give:

[tex]x^5-5x^4+3x^3-3x^2+7x+20[/tex]

but,

[tex]x^5+3x^3-3x^2+7x+20-5x^4[/tex] is not in standard form.

For this question, I can simply give the answer: [tex]x^5-5x^4+3x^3-3x^2+7x+20[/tex] and it is correct.

But I will create a fifth-degree polynomial using this formula

[tex]$(a+b)^n=\sum_{k=0}^n \binom{n}{k} a^{n-k} b^k$[/tex]

Also, note that

[tex]$\binom{n}{k}=\frac{n!}{(n-k)!k!}$[/tex]

For [tex]a=x \text{ and } b=7[/tex]

[tex]$\left(x + 7\right)^{5}=\sum_{k=0}^{5} \binom{5}{k} \left(x\right)^{5-k} \left(7\right)^k$[/tex]

[tex]\text{Solving for } k \text{ values: } 0, 1, 2, 3, 4 \text{ and } 5[/tex]

Sorry but I will not type every step for each value of [tex]k[/tex]

The first one is enough.

For [tex]k=0[/tex]

[tex]$\binom{5}{0} \left(x\right)^{5-0} \left(7\right)^{0}=\frac{5!}{(5-0)! 0!}\left(x\right)^{5} \left(7\right)^{0}=\frac{5!}{5!} \cdot x^5= x^{5}$[/tex]

Doing that for [tex]k[/tex] values:

[tex]\left(x + 7\right)^{5}=x^{5} + 35 x^{4} + 490 x^{3} + 3430 x^{2} + 12005 x + 16807[/tex]

The company requires a minimum cash balance of $ 7 comma 600. January cash collections are $ 548 comma 570. Total cash payments for January are $ 567 comma 610. Prepare a cash budget for January. How much cash, if any, will Howard need to borrow by the end of January? Divide. Plssssss I forgot how The velocity selector in in a mass spectrometer consists of a uniform magnetic field oriented at 90 degrees to a uniform electric field so that a charge particle entering the region perpendicular to both fields will experience an electric force and a magnetic force that are oppositely directed. If the uniform magnetic field has a magnitude of 37.8 ~\text{mT}37.8 mT, then calculate the magnitude of the electric field that will cause a proton entering the velocity selector at 40.640.6 km/s to be undeflected. Give your answer in units of kV/m. how would you solve this problem? Suppose the mean height for adult males in the U.S. is about 70 inches and the standard deviation is about 3 inches. Assume mens heights follow a normal curve. Using the Empirical Rule, 95% of adult males should fall into what height range?
