Answer 1
Answer: Hello!

Reading these types of graphs can be difficult, but it displays the following numbers:

27, 30, 31, 43, 45, 49, 51, 58, 62, 64

To find mean, or average, you need to add up all of the numbers and divide by how many there are (10)

This will give you 46.

I hope this helps you and good luck!

A right triangular prism has a height of 26 cm and base edges of 10 cm, 24 cm, and 26 cm. What is the lateral area of the prism? A.1560 cm2
B.1680 cm2
C.800 cm2
D.3120 cm2

Answers

The lateral area is 1560 cm².

The lateral area is the area of the lateral faces (the faces that are not bases).  The dimensions of these are:
24 by 26
10 by 26
26 by 26

These are all rectangles.  The area of each rectangle is given by length * width:
24*26 = 624
10*26 = 260
26*26 =676

624+260+676=1560

You need to work this out using pythagoras' theorem.

Csquared=Asquared+Bsquared

But you are finding out A, not C, so you must rearrange the equation.

Asquared=Csquared-Bsquared
Asquared= 484-256
Asquared=228
A=Square root of 228
A=15 :)

Anna wants to bake 2 1/2 dozen cookies for a party. However, the recipe she has only makes a dozen cookies. If the original recipe calls for 1 1/4 cups of sugar, how many cups of sugar does she need to make the cookies for her party? Express your answer as a mixed number.

Answers

Given :

Sugar required for 2 1/2 = 5/2 dozen of cookies is 1 1/4 = 5/4 cups.

To Find :

How many cups of sugar does she need to make the cookies for her party.

Solution :

Let, cups of sugar required to make cookies for her party is x.

So,

x = ((5)/(4))/((5)/(2))\n\n\nx = (1)/(2)

Therefore, 1/2 cup of cookies is required to make 1 dozen cookies.

Hence, this is the required solution.

Answer: 25/8

Step-by-step explanation:  

We would first turn 2 1/2 and 1 1/4 into an improper fraction.

That leaves us with 5/2 and 5/4.

Then, because she needs to make 5/2 dozen cookies and needs 5/4 cups of sugar for every batch, we would multiply 5/2 and 5/4 together.

Therefore x, or the amount of sugar she needs, is 25/8

Principal: $9,000, annual interest: 3%, interest periods: 12 , number of years: 13

Answers

Answer:

Step-by-step explanation:

P: the principal, amount invested

A: the new balance

t: the time

r: the rate, (in decimal form)

n: the number of times it is compounded.

Ex2:Suppose that $5000 is deposited in a saving account at the rate of 6% per year. Find the total amount on deposit at the end of 4 years if the interest is:

P =$5000, r = 6% , t = 4 years

a) simple : A = P(1+rt)

A = 5000(1+(0.06)(4)) = 5000(1.24) = $6200

b) compounded annually, n = 1:

A = 5000(1 + 0.06/1)(1)(4) = 5000(1.06)(4) = $6312.38

c) compounded semiannually, n =2:

A = 5000(1 + 0.06/2)(2)(4) = 5000(1.03)(8) = $6333.85

d) compounded quarterly, n = 4:

A = 5000(1 + 0.06/4)(4)(4) = 5000(1.015)(16) = $6344.93

e) compounded monthly, n =12:

A = 5000(1 + 0.06/12)(12)(4) = 5000(1.005)(48) = $6352.44

f) compounded daily, n =365:

A = 5000(1 + 0.06/365)(365)(4) = 5000(1.00016)(1460) = $6356.12

The present value of the money in your savings account is $420, and you're receiving 3% annual interest compounded monthly. What is the future value in two months?
