E ==5e + 3f = -36-e + 2f = 2f = 1

Answers

Answer 1

Answer:

e = -6

f = -2

Step-by-step explanation:

I used the elimination method and multiplied the second equation by 5 to get:

  -5e + 10f = 10.  Added this to:

+  5e + 3f = -36

13f = -26

f = -2

now find e:  -e - 4 = 2

-e = 6

e = -6

If cos 0 = 3/5
and angle 0 is in Quadrant IV, what is the value of tan 0 ?
Tan =

Answers

Answer:

-4/3.

Step-by-step explanation:

cos O = 3/5

Using Pythagoras to find the length of the side opposite  the angle O:

As the  cos of O is adjacent/ hypotenuse,  Hypotenuse = 5 , adjacent side = 3 so

opposite side. = sqrt(5^2 - 3^2) = sqrt 16

= 4.

Now the tangent is negative in Q IV so

tan O =  opposite / adjacent side = -4/3

A new bank customer with ​$4,000 wants to open a money market account. The bank is offering a simple interest rate of 1.2​%.

a. How much interest will the customer earn in 30 ​years?
b. What will the account balance be after 30 ​years?

Answers

Answer:

Interest: $1440

Total Account Balance: $5440

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 1.2%/100 = 0.012 per year,

then, solving our equation

I = 4000 × 0.012 × 30 = 1440

I = $ 1,440.00

The simple interest accumulated

on a principal of $ 4,000.00

at a rate of 1.2% per year

for 30 years is $ 1,440.00.

The simple Interest is $1440 and the total Account Balance: $5440.

What is simple interest?

Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest.

First, converting R percent to r a decimal,

r = R/100 = 1.2%/100 = 0.012 per year,

Then, solving our equation,

I = 4000 × 0.012 × 30 = 1440

I = $ 1,440.00

The simple interest accumulated,

on a principal of $ 4,000.00

at a rate of 1.2% per year

for 30 years is $ 1,440.00.

Therefore, the simple Interest is $1440, and the total Account Balance: $5440.

On a map of hiking trails, 0.5 inch represents 1 mile. A trail is shown as 1.25 inches long on the map. How long is the actual trạil?

Answers

Answer:

2.5 miles

Step-by-step explanation:

Answer:

The actual trail length is 2.5 miles.

Step-by-step explanation:

Let's solve this. 0.5 inches on the scale = 1 mile. Since the trailer is 1.25 inches long on the scale, let's first multiply 0.5 by 2. You would get 1 inch on the scale, which would be 2 miles.

2 miles = 1 inch on the scale. But it says 1.25, so since 0.5 inches is 1 mile, then 0.25 inches is 0.5 miles. Add 2 miles and 0.25 miles, and you will get 2.5 miles.

The trailer length is 2.5 miles.

y = -25x + 170

Step-by-step explanation:

For the graph equation y = ax + b, we have to find a and b.

Pick two points that are on the grid for best accuracy.

e.g., (2,120) and (6,20)

Then a = (20-120)/(6-2) = -25

b is the y coordinate of the line with the y axis: 170

So the formula is:

y = -25x + 170

24 is 3/4% of what number

Answers

24 is 3/4 of the number 32

Answer:

32

Step-by-step explanation:

Alright, so think of the "what number" as x in this case. (Or any number/symbol you choose.)

So our simple equation looks something like this:

[tex]24= x *\frac{3}{4}[/tex]

So, to find out what the "what number" would be we'd flip the fraction around/find the reciprocal and multiply 24 by it. That gives us "x" or the number we're missing.

So: [tex]24 * \frac{4}{3} = x[/tex]

Doing the simple math we get:

[tex]24 * \frac{4}{3} = 32[/tex].

32 is your answer.
