Answer 1

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

we can find angle C  b/c the angles of a triangle always add to 180 , soo

180= C + 81 +63.5

35.5 = C

now that we have angle C and we know the Hyp we can use sin to find side g

where g = Opp and Hpy = 13.8 for this question

Sin(35.5) = Opp / 13.8

13.8*Sin(35.5) = Opp

8.0137 = Opp

g = 8.0137

next they ask for the area of the biggest triangle  ABC ( there are two smaller ones when you use D )

we can use 1/2 * base * height , but we don't know the base yet, even thou we do know the height.  

we can solve for line segment CD and DB and then add them for the side a .. or the base of the biggest triangle sooo.. CD = adj

Cos(35.5) = Adj / 13.8

13.8*Cos(35.5) = Adj

11.234794 =Adj

now solve for DB using cos again but with the other smaller triangle where  Adj = DB now

Cos(63.5) = Adj / 8.9

8.9*Cos(63.5) = Adj

3.971160

add these two Adjs together to get the total  'a' side

15.205954

now plug in side a as the base and g as the height of our biggest triangle

Area = 1/2 * 15.205954 * 8.0137

Area = 60.9159

rounded to 2 sig figs

Area = 60.92   :)   hope you get an "A"    :P

Solve the variable for 2e=6.8

Answers

Answer:

e=3.4

Step-by-step explanation:

Your equation is 2e=6.8

All you have to do is divide both sides by 2 and get that:

e=3.4

The solution for 2e=6.8 is 3.4

What is equation?

Equation, statement of equality between two expressions consisting of variables and/or numbers.

Given equation is: 2e=6.8

Divide both by 2, to make the coefficient of e 1.

2e/2=6.8/2

e=3.4

Hence, the solution of the equation is 3.4.

2). Write an equation and solve. You will not be given credit for your answer if you do not include your equation! This month's cell phone bill was for $15.27 more than last month's cell phone bill. If this month's phone bill is for $72.50, how much was last month's cell phone bill?​

Answers

Answer:

Equation is:     x+15.27 = 72.50Solution to that equation:    x = 57.23Interpretation:   Last month's phone bill was $57.23

========================================================

Explanation:

We'll make x the value of last month's phone bill. So if lets say x = 50, this means that last month's phone bill was $50. We don't know yet if x = 50 is the actual solution or not.

We're told that "This month's cell phone bill was for $15.27 more than last month's cell phone bill". This means this month's bill, in terms of x, is x+15.27 dollars. Whatever x is, we add 15.27 onto it getting this month's bill. This works because x is really a placeholder for a number.

Going back to x = 50, that would mean this months bill is x+15.27 = 50+15.27 = 65.27 dollars. We can see that we don't reach 72.50 that we're told the current months bill actually is. Since we don't have a match, this means x = 50 is too small. We can guess and check our way to hopefully land on the answer. However, using algebra is the most efficient method.

----------

The equation we need to solve is:   x+15.27 = 72.50

This is because x+15.27 represents this month's bill and so does the 72.50, as your teacher gave in the instructions.

To solve this equation, we'll undo the "plus 15.27" to isolate x fully. The opposite of addition is subtraction. We'll subtract 15.27 from both sides

x+15.27 = 72.50

x+15.27-15.27 = 72.50-15.27

x = 57.23

Last month's phone bill was $57.23

As a check, adding 15.27 onto last month's bill should get us to 72.50

x+15.27 = 57.23+15.27 = 72.50

It works out, so we've confirmed the answer.

Bilal and Charlie have some sweets. Bilal has 4 times as many sweets as Charlie. Bilal gives Charlie 15 of his sweets and now they have the same amount. How many sweets do they have altogether?

Answers

Answer:

50

Step-by-step explanation:

The computation of the number of sweets they do have altogether is as follows:

Let us assume Charlie sweets be x

So bilal sweets is 4x

Now Bilal gives Charlie 15 of his sweets due to which they must have the same amount

4x - 15 = x + 15

4x -x = 15 + 15

3x = 30

x = 10 = Charlie sweets

Bilal sweets = 4x = 4(10) = 40

So the total no of sweets held by them is 50

The least amount of time spent is : 1

The most amount of time spent is : 3 3/4

From Julie's assertion, that the most amount of time spent is equal to 1 1/2 the least amount of time spent.

Most amount of time = 1 1/2 * least amount of time

3 3/4 = 1 * 1 1/2

15/4 = 3/2

However, 15/4 ≠ 3/2

Find two consecutive numbers if square root of the bigger number is 5 less than the smaller number

Answers

9 and 8, square root of 9 is 3 which is 5 pess than 8

Using a system of equations, it is found that the two consecutive numbers can be 8 and 9, or 3 and 4.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the numbers are consecutive, hence they are n(smaller number) and n+1(larger number).

The square root of the bigger number is 5 less than the smaller number, hence:

[tex]\sqrt{n+1} = n - 5[/tex]

[tex](\sqrt{n+1})^2 = (n - 5)^2[/tex]

[tex]n^2 - 10n + 25 = n + 1[/tex]

[tex]n^2 - 11n + 24 = 0[/tex]

[tex](n - 8)(n - 3)[/tex]

The solutions are n = 8 and n = 3. Hence, the consecutive numbers can be 8 and 9, or 3 and 4.
