Answer: A
Step-by-step explanation: 107 is larger than 30
Answer:
To find the number of nickels and dimes, we can use this equation: 0.10d + 0.05n = 5.25
We are given the information that Sonji has 21 dimes (which means that d=21). We can use the equation to find the number of nickels n.
0.10d + 0.05n = 5.25
0.10(21) + 0.05n = 5.25
2.10 + 0.05n = 5.25
0.05n = 3.15
n = 3.15 / 0.05
n = 315 / 5
n = 63
Sonji has 63 nickels.
Let's check our answer.
21(0.10) + 63(0.05) = 2.10 + 3.15 = 5.25
It seems that our answer is correct.
Step-by-step explanation:
Answer:
1.the angle of a triangle is 180
2. it depends on the triangle, if it is an equalatral all angles are 60
Because all the sides are equal
Here we want to analyze the given exponential equation. The answers are:
- initial value = 7500
- Rate of growth = 1.03
- Percent of change = 3%
<h3>
General exponential equation:</h3>
The general exponential equation is just:
y = A*(r)^x
Where:
- A is the initial value
- r is the rate of growth or decay
- (r - 1)*100% gives the percent of change.
Now that we know the general form, we can look at our equation:
y = 7500*(1 + 0.03)^x
Using the above information, we can see that:
- initial value = 7500
- Rate of growth = 1 + 0.03 = 1.03
- Percent of change = (1.03 - 1)*100% = 3%
