First of all on the graph when you see it’s 5 seconds it has 50 distance traveled so 50/5 = 10 so number 2 would be t=10
Answer:
The circumference of a circle is pi times diameter, so half-way around the pond is (1/2)pi times diameter.
The difference between walking around the pond and walking across the bridge is: 1.57d - d = 0.57d
Plug in diameter of 0.25
0.25*0.57 = 0.14 miles
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
9/5 = z/20
First, we have to divide what we know
9/5 = 1.8
1.8 = z/20
Next, we have to multiply both sides of the equation by 20 to cancel out the division sign
1.8•20 = z/20•20
36 = z
Answer:
The number of students in the school band = 70
40% of students in the school band are sixth graders.
20% of students in the school band are seventh graders.
We have to find the number of band members that are sixth graders.
The number of sixth graders in school band are:
![40\% of 70](https://tex.z-dn.net/?f=40%5C%25%20of%2070)
![0.40 \times 70](https://tex.z-dn.net/?f=0.40%20%5Ctimes%2070)
![28](https://tex.z-dn.net/?f=28)
Therefore, there are 28 band members that are sixth graders.
In this item, we let x be the amount that is deposited in the account that has a simple interest equal to 7%. With this representation, the amount that is deposited in the account with simple interest of 6% is equal to 12000 - x.
The amount of interest earned from the investment is calculated through the equation,
I = P x (i)
For the first investment,
I = (x)(0.07)
For the second investment,
I = (12000 - x)(0.06)
Adding up the interests,
800 = 0.07x + (0.06)(12000 - x)
The value of x from the equation is 8000.
<em>Therefore, the amount invested to that with 7% interest is $8000 and the amount invested to that with 6% interest is $4,000.</em>
