Diana invested $3000 in a savings account for 3 years. She earned $450 in interest over that time period. What interest rate did she earn? Use the formula I=Prt to find your answer, where I is interest, P is principal, r is rate and t is time. Enter your solution in decimal form rounded to the nearest hundredth. Fr example, if your solution is 12%, you would enter 0.12.

Answers

Answer 1

Answer:

0.05

Step-by-step explanation:

we are given the formula

I = Prt, where

I = interest earned = $450

P = Principal amount = $3000

t = time = 3 years

r = rate (we are asked to find this_

Simply substitute the known values into the equation

I = Prt

450 = 3000 x r x 3

450 = 9000r

r = 450/9000

r = 0.05

lisa an experienced shipping​ clerk, can fill a certain order in 7 hours. ​bill, a new​ clerk, needs
8 hours to do the same job. Working​ together, how long will it take them to fill the​ order?

Answers

Answer:

3.73 hours

Explanation:

In 1 hour, Lisa does 1/7th of the order while Bill does 1/8th of the order in an hour. To find out how long it will take them to fill the order, we have to:

Step 1:

Add the rate of both Lisa and Bill together

1/7 + 1/8

Step 2:

Since both denominators of the fractions are different, you have to find the least common multiple of 7 and 8

7·8= 56    8·7= 56

which is 56.

Step 3:

Then, you have to multiply the numerator of 1/7 with 8 and the numerator of 1/8 with 7.

1·8= 8    1·7= 7

The fractions would now have equal denominators:

Lisa: 8/56    Bill: 7/56

Step 4:

Now, you can add them together

8/56 + 7/56

which equals to 15/56. Both Lisa and Bill together completes 15/56th of the order in 1 hour.

Step 5:

15/56 is not the final answer as it is the RATE of them working together. To find how long it will take them total to complete the order, you must divide 56 with 15.

56/15

which is 3.73 hours in decimal form (rounded).

Write the equation of the line with the given point and slope.
(-5, -3); slope = -3/5

Answers

A line in point slope form is y = mx + b

m = the slope

b = y-intercept

So far our line looks like: y = -3/5x + b

Let's plug -5 into x and -3 into y to solve for b

-3 = -3/5(-5) + b

Let's multiply -5 by -3/5

-3 = 3 + b

Subtract 3 from both sides.

-6 = b

Our line is: y = -3/5x - 6

The equation y =0.7x represents the distance Henry hikes in miles over time in hours. The graph
represents the rate that Cark hikes. Determine which hiker is faster. Complete the explanation


Henry’s unit rate is ___ miles per hour. Clark’s unit rate is 1.5 miles per hour . So, ____ is faster.

Answers

Answer:

Henry’s unit rate is 0.7 miles per hour. Clark’s unit rate is 1.5 miles per hour . So, Ckark is faster.

Step-by-step explanation:

Distance covered by Henry is represented by y = 0.7x, where x = time (hrs), and y = distance (miles).

Distance covered in 1 hour by Henry would be:

y = 0.7(1) = 0.7 miles per hour

Distance covered by Clark in 1 hour = 1.5 miles per hour

Ckark covers more miles per hour than Henry covers in one hour, therefore, Ckark is faster.

Answers

Answer:

1. b     2. b

Step-by-step explanation:

1. In the graph it shows a negative slope so we can immediately eliminate a and c since they have a positive slope as shown in the equation. Then the initial value is the y coordinate when x is 0. In the graph you can see that when x is 0 y is 18 so the equation would be h= -3+18

2. In the problem it says that Jennifer is paid $2,200 as a base salary. This means that this is her initial value. Then you can see that she gets paid 300 extra for every car she sales. This is the rate of change. The equation will be y=300x+2,200

fyi 300 goes first because it is the rate of change and those always go first.
