Answer:

B=1 and the rest Im unsure of sorry hope this helps

Step-by-step explanation:

The total amount in the account after 1 year will be $420

Based on the information given, the following can be deduced:

Principal = $400

Interest rate = 5%

Time = 1 year

Therefore, the simple Interest will be:

= PRT/100

= ($400 × 5 × 1)/100

= $2000/100

= $20

Therefore, the amount will then be:

= Principal + Interest

= $400 + $20

= $420

Therefore, the total amount is $420

Answer:

 y = -1/2x -3

Step-by-step explanation:

The line perpendicular to one with a slope of 2 will have a slope that is the negative reciprocal of 2, that is, -1/2. The given point is the y-intercept of the required line, so we can write its equation directly in slope-intercept form:

y = mx + b

where m is the slope (-1/2), and b is the y-intercept (-3). Your line is ...

 y = -1/2x -3

Answer:

75% of 60 = 45

Step-by-step explanation:

In order to find the answer to this question you need to divide the percentage of the number by one-hundred and then divide that number by the number the number you are trying to find the percentage of.

60/x=100/75

(60/x)*x=(100/75)*x        

60=1.33333333333*x      

(1.33333333333) to get x

60/1.33333333333=x

45=x

x=45

75% of 60 = 45

Answer: X = 9

Step-by-step explanation:

First insert the function into a graphing calculator.

We are trying to find the x intercepts, we substitute y=0.

With a graphing calculator look at where the line intercepts the x axis, (9,0) , and we find that x=9.

Answer:

the right answer is x = 9/2

Answer:

A) Dilated 150% then reflected across the x-axis

Step-by-step explanation:

By counting the squares of shape A, you can see that 2 squares = 100% and 1 square = 50%. You can then count 2 squares into shape B (because that is your starting point) and then count the remaining squares, which is 3. 3 squares is equal to 150% so we know there is a 150% dilation.

We can then also see shape A has been reflected across the x-axis to give shape B.

Answer:

212=70+(m X 0.40)

If $212 is the total cost for a one-day rental, the number of miles driven is 455 miles.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Cost of car rent per day for 100 miles = $70

Additional cost per mile = $0.40

Let m = number of miles driven

Total cost for one day rental = $212

The equation that represents the additional m = miles driven for a day that cost $212 is:

212 - 70 = 0.40m

142 = 0.40m

m = 142 / 0.40

m = 355

This means 355 additional miles were driven.

The number of miles driven for the day is:

= 100 + 355

= 455 miles

Thus if $212 is the total cost for a one-day rental, the number of miles driven is 455 miles.

Answer:

In my thinking the answer is 9.

Step-by-step explanation:

the slope (or gradient) of a line is the factor of x.

in our case here : 3

it is expressed as ratio y/x and represents the amount of units y changes (and via the sign in what direction), when x changes a certain amount of units (again, via the sign in what direction). like when going from a point 1 to a point 2.

so, here we have 3 = 3/1, and that means, when x changes by 1 unit to the right (positive), y changes 3 units up (positive).

the y-axis intercept is simply the point, where x = 0. clearly, any point with the x coordinate being unequal to 0 cannot be on the y axis.

so, here

y = 3×0 + 7 = 7

=>

the y-axis intercept point is (0, 7).

Answer:

Length = 21

Width = 16

Step-by-step explanation:

We know that the formula for perimeter is:

P=2W+2L

And we also know that:

L=W+5

So then we put all that we know in the formula:

74=2W+2(W+5)

Now we expand the brackets and do some algebra:

74=4W+10 (-10)

64=4W (÷4)

16=W

Now that we know the width we can pop that into the length equation:

L=16+5

L=21
