Answer:
The x intercept is (-5,0)
The y intercept is (0,-3)
Step-by-step explanation:
To find the x intercept we set y=0 and solve for x
3x+5y = -15
3x+0 = -15
3x = -15
Divide by 3
3x/3 = -15/3
x = -5
The x intercept is (-5,0)
To find the x intercept we set x=0 and solve for y
3x+5y = -15
0+5y = -15
5y = -15
Divide by 5
5y/5 = -15/5
y = -3
The y intercept is (0,-3)
1: not sure what you mean
2: to add and subtract, get common denominator. To multiply, multiply the terms horizontally. To divide, multiply by the reciprocal
3: multiply by reciprocal. Multiply the number part and fraction part.
4: volume=length*width*height
5: count all the cubes inside
Answer:
Step-by-step explanation:
time taken to complete the second half=65.49-31.73=33.76 seconds
Given:
Desmond deposits $ 50 monthly.
Yearly he deposits = $50×12 = $ 600
Rate of interest compounded monthly = 4.7%
To find the amount he will receive after 10 years and the rate of change the value of his account after 10 years.
Formula
where,
A be the final amount
P be the principal
r be the rate of interest
t be the time and
n be the number of times the interest is compounded.
Now,
Taking,
P = 600, r = 4.7, n = 12, t = 10 we get,
or,
or,
Now,
At starting he has $ 600
At the end of 10 years he will be having $ 959.1
So,
The amount of change in his account = $ (959.1-600) = $ 359.1
Therefore the rate of change =
= 59.85%
Hence,
a) His account will contain $ 959.1 after 10 years.
b) The rate of change in his account is 59.85% after 10 years.
Answer:
15 miles
Step-by-step explanation:
9 miles is 60% of the total
We can translate this to an equation. Remember:
- "IS" means "EQUAL"
- "OF" means "MULTIPLICATION"
- Percentage should be converted to decimal first by dividing by 100
- Let total be t
60% will be 60/100 = 0.6
Now, translating the word problem into an equation:
Now, we solve for total (t):
Hence, she ran 15 miles all week
