dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year. how much will he earn in 4 years?

Answers

Answer:

= $655.20

Step-by-step explanation:

Simple Interest =( Principal * rate * time)/100

                          =( $ 6300 * 2.60% * 4years)/100, workout in the brackets first then divide by 100.

                        =   65520/100

                        = $655.20

Dexter will earn $655.2.

What is the simple interest?

Simple interest is the borrowing amount added only to the principal amount.

Formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100 ,

Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.

Dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year.

P = $6300

R = 2.60% and T = 4 years

Then by the formula;

6300 x 2.6 x 4 /100

= $655.2

Therefore, Dexter will earn $655.2.

Answer:

25. y=2x+1

26. $13

Step-by-step explanation:

25. 2x is the cost each day or the x, and the 1 is the initial fee, I found this because it said one day costs $3 and if I know that one days fee is $2 then I know that the y intercept or the price it starts at also known as a fee is $1. This is also backed up in the 4 day statement saying that 4 days is 9 dollars. I can do 9-1 to take away the fee and 8/2=4 so it is correct.

26. Since I already have the equation I can just plug in the vales and solve. y=2x+1, x=2 or the daily cost so 12+ (the fee) 12+1=13 so $13.

good luck, and have a great day.    :)

For 25 the answer would be y = 2x +

Write and solve an equation that can be used to find x, in the figure below:

Answers

Answer: x=40

Step-by-step explanation:

so you would add the two angles you already know.

30+63=93

The sum of the angles of a triangle is always 180°. Knowing this, you can do

180-93=87

so you know the third angle is 87°

plug this into the equation: 2x+7

2x+7=87

subtract both sides by 7

2x=80

divide by two

x=40

The correct answer is X=40 because

1. Add the 2 angles you already know.

30 + 63 = 93

2. The sum of all angles in a triangle is always 180°

180 - 93 = 87

3. third angle is 87°

2x + 7 = 87

4. Subtract BOTH sides by 7

2x = 80

5. Divide by 2

X = 40

Sam drew a rectangle measuring 9 feet in length by 15 feet in width. If she wants to make a similar rectangle measuring 27 feet in length, what should the width be?

Answers

Answer:

45

Step-by-step explanation:

If sam made a rectangle 9 feet in length and 15 in width. And we already know the next rectangle is 27 feet we can divide it by 9.

27/9=3

Now that we know its 3x the normal size we can grab the 15 and multiply it by 3.

15x3=45

in short: the answer is 45

Answer:

The answer is that angle 1 is 70 degrees.

Step-by-step explanation:

Alright so all vertical angles are congruent and the sum of all angles IN and triangle equals 180 degrees. So, the angle on the inside of the top of the triangle is 60 degrees because vertical angles are congruent. Now the angle across from the 130 degree angle is 130 degrees, and we know that the outer and inner angles are supplementary, (add up to 180 degrees) so the angle on the inside is 50 degrees. Then, all angles of a triangle equal 180 degrees therefore, 180-(60+50)= the final angle. Now 70 degrees is the last angle and this angle is vertical to angle 1 which means that angle 1 equals 70 degrees.

Without solving, identify whether this equation has a solution that is positive,negative, or zero:3x-5=-3
