■ Answer:

a = 141°

b = 13°

c = 26°

■ Step-by-step explanation:

a = 128 + b

c = 2b

a + b + c = 128

replace a & c

(128 + b) + b + 2b = 180

4b = 180 - 128

4b = 52

b = 13°

a = 128° + 13° = 141°

c = 2×13° = 26°

We can write an equation using the information given in the problem.

2x + x + x + 128 = 180

Solve for x.

4x + 128 = 180

4x = 52

x = 13

Second angle:

13 + 128 = 141

Third angle:

13 * 2 = 26

Therefore, the answer is [ 13, 26, and 141 ]

Best of Luck!

Problem Page A principal of $2100 is invested at 7.75% interest, compounded annually. How much will the investment be worth afte
just olya [345]

Answer:

After 12 years the investment will be worth $5145.

Step-by-step explanation:

The formula used for compounded interest is:

A = P(1+r/n)^nt

where,

A = future value

P = Principal Amount

r = interest rate

n = no of times interest is compounded

t = time

In the question given:

A=?

P = $2100

r = 7.75% or 0.0775

n = 1

t= 12

A= 2100*(1+0.0775/1)^1*12

A= 2100 *(1+0.0775)^12

A= 2100 *(1.0775)^12

A= 2100 * 2.45

A= 5145

So, after 12 years the investment will be worth $5145.

I WILL NAME YOU THE BRAINLIEST!
OlgaM077 [116]

Answer: c=5.4

The two roots are 3/5 and 9/5


Step-by-step explanation:

assume 5x2−12x c=0 is supposed to be 5x^2 - 12x + c = 0

p = (12 + sqrt(144-20c))/10

q = (12 - sqrt(144-20c))/10

p-3q=0,

1.2 + 0.1sqrt(144-20c) +

-3.6 + 0.3sqrt(144-20c) = 0

-2.4 + 0.4sqrt(144-20c) +2.4 = 2.4

sqrt(144-20c) = 2.4/0.4 = 6

144-20c=36

144-36=20c

c = 108/20 = 5.4

5x^2-12x+5.4=0

x = 3/5 or x = 9/5

How do you this??<br><br> Scientific notation
Airida [17]
So Scientific Notation is a "simplified version" of a number. For example, is your number is 2,345, the scientific notation would be 2.345 * 10³. 

If it was 0.023, then the scientific notation would be 2.3 * 10^-2. 

Scientific notation is found by moving the decimal place to the left or right, until only one digit is left to the left of the decimal; it has to be greater than 1, but less than ten. If you move the decimal place to the right, it's a negative power of 10. If you move it to the left, it is a positive power of 10.


Hope this helps!
