Since the triangle is isosceles, then (x + 4) must be equal (3x - 8)

Solving the (x + 4) = (3x - 8), we'll get:

(x + 4) = (3x - 8)

3x - x = 8 + 4

2x = 12

x = 6

So, the length of AC is 6 units

A church building fund has invested some money in two ways: part of the money at 7% interest and four times as much at 11%. Find
aliya0001 [1]

Answer: he invested $15000 in part 1 and $60000 in part 2

Step-by-step explanation:

Let x represent the amount of money invested in part one.

Let 4x represent the amount of money invested in part 2 .

Total amount of money invested in part 1 and part 2 is

x + 4x = 5x

The formula for simple interest is expressed as

I = PRT/100

Where

P is the principal or initial amount.

T is the duration in years

R is the number rate.

For part 1

R = 7%

T = 1 year

P = x

I = (x × 7 × 1)/100 = 0.07x

For part 2,

R = 11%

T = 1 year

P = 4x

I = (4x × 11 × 1)/100 = 0.44x

if the total annual income from interest is 7650. This means that

0.44x + 0.07x = 7650 - - - - - - - -2

0.51x = 7650

x = 7650/0.51

x = 15000

Amount invested in part 1 is $15000

Amount invested in part 2 is 4×15000 = $60000

Find the secant of angle Z<br> A.4/5<br> B.4/3<br> C.3/5<br> D.5/3
Alex73 [517]

Answer:

D 5/3

Step-by-step explanation:

Secθ= Hypotenuse/Adjacent

Secθ=10/6

Simplify: 10/6 -->5/3

Ans: D 5/3

remember your six trigonometric functions:

Sinθ=Opp/Hyp -->Cscθ=Adj/Hyp

Cosθ=Adj/Hyp -->Secθ=Hyp/Adj

Tanθ=Opp/Adj-->Cotθ=Opp?Adj

It is basically the opposite of each other, don't forget when you are at the last step you simplify! never forget. Also working with square roots will be a bit tricky when converting to Csc/ Sec/ Cot. Just noting you that Square roots don't belong in denominators!

Is 1/4 less than or greater than 1/8
lana66690 [7]
To find this answer, you need to find a common denominator. A common denominator is when the number on the bottom of two fractions is the same. The easiest was to do this is to first multiply the two denominators, then multiply the numerator (or top number) by the opposite denominator. This sounds complicated, but it's pretty simple. Here's the equation written out. (I hope this helps!)

4*8 = denominator for both numbers.

8*1 = numerator for the first number

4*1 = numerator for the second number.

This should give you the fractions with common denominators, 8/32 and 4/32. Then, to compare the fractions, just see which numerator is larger. In this case, 8 is larger than 1 which shows that 1/4 is greater than 1/8.

I hope this made sense. There's more than one way to solve these problems, so comment below if you would like me to explain it differently and I'll get back to you as soon as I can!  :)
