Answer
Find out the total amount of interest earned at the end of 3 years .
To prove
Formula
As given
Dawnie deposited $350 In a savings account earns 3% simple interest over three years .
Here Principle = $350
Interest = 3%
Time = 3 years
Put in the above formula
Simple interest = $31.5
Therefore $31.5 is the total amount of the interest in 3 years.
Answer:
9
Step-by-step explanation:
Slope is the same as coefficient of x
From the equation
3x+4y=12
Y=(-3/4)x+3
The slope for this eqn is -3/4
For this equation
Px+12y=30
12y=-p+30
Y= (-p/12)x +30/12
The slope is -p/12
To get p
-p/12=-3/4
P=9
Answer:
(3x-4)(x-5)
Step-by-step explanation:
This is in the form
ax²+bx+c.
To factor this, we find factors of a·c that sum to b; this means factors of 3(20) = 60 that sum to -19:
60 = 1(60) or -1(-60); 2(30) or -2(-30); 3(20) or -3(-20); 4(15) or -4(-15); 5(12) or -5(-12); 6(10) or -6(-10). The only of these that sum to -19 are -4 and -15. This means we will split up -19x into -4x and -15x:
3x²-4x-15x+20
Next we group the first two terms and the last two terms:
(3x²-4x)+(-15x+20)
Factor out the GCF of each group. For the first group, this is x:
x(3x-4)
For the second group, this is -5:
-5(3x-4)
The common factor for these two groups is (3x-4):
(3x-4)(x-5)
Answer:
15
Step-by-step explanation:
Use Pythagorean theorem.
c² = a² + b²
c² = 9² + 12²
c² = 225
c = 15
I believe it’s C because none of the others are even close and the 3 and 7 add up correctly
