Hank put $10,000 in an account for 10 years. The account earned 2.5% interest. How much interest had been earned by the end of the 10 years?

Answer:

-4e-9

Step-by-step explanation:

3e-19-7e+10

3e-7e-19+10

-4e-9

The simplified expression is -4e - 9.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

3e - 19 - 7e + 10

Combine like terms.

(3e - 7e) - 19 + 10

-4e - 9

Thus,

The final expression is -4e - 9.

Answer:

C. Infinite Solutions

Step-by-step explanation:

In order to solve this we fist have to simplify the equation so we do the following:

[tex]\frac{1}{7}(63n -77) = -11 + 9n\\\\(\frac{1}{7})(7)(63n - 77) = (7)(-11 + 9n) \\\\63n - 77 = -77 + 63n\\63n - 77 = 63n - 77[/tex]

From here we know that any value of n is the solution of this equation so the answer is option C.

Step-by-step explanation:

Answer:

2 teaspoons for the two frozen cookies

3/4 a cup for the cooking oats

2 cups for the flour

Step-by-step explanation:

First Question

The recipe makes 18 cookies. Divide the cookies by 9, half of the batch, to get 2. Now all you have to do is devide the amount of vanilla extract by 9, it will give you two teaspoons.

1 and 1/2 devided by two since you're devidng the recpie by two to get 9 cookies. A cup is four so 3/4 plus 3/4 equals 6/4. Simplified it'd be 1 and 1/2 or 1 and 2/4.

The recipe already calls for 1 and 1/2 a dozen. All you're doing is multiplying the recipe b two to get 3 dozen cookies. Now focusing our attention to the flour, there is 1 cup for 1 and 1/2. Multiply 1 by 2 since there is already half of the recipe here. 1 and 1/2 + 1 and 1/2 is 3 so there'd be 2 cups. Basically just double the recipe.

Answer:

Let's define the variables:

D = arrangements of daisies that he buys

R = arrangements of roses that he buys.

Each arrangement of daisies costs $4.25, then for D of them, the total cost is:

D*$4.25

And for the roses, the cost of each one is $6.50, then the cost for R of them is:

R*$6.50

We know that he wants to spend less than $39, then we have the inequality:

D*$4.25 + R*$6.50 < $39

And we also know that he wants to buy at least, 4 arrangements, then:

D + R ≥ 4

Now we have a system of inequalities:

D + R ≥ 4

D*$4.25 + R*$6.50 < $39

This has quite a few solutions, for example, he could buy 3 arrangements of daisies and 2 of roses, the total cost would be:

3*$4.25 + 2*$6.50 = $25.75, which is less than $39, and he is buying 5 arrangements, more than 4 as he wanted.

And there are a lot of other possible options.

Answer:

Bag of lemon

Step-by-step explanation:

Given that:

Cost of loose lemon = $0.99 for 2

Cost of bag of lemon = $2.50 for 6

Calculating the cost per 1 for loose and bag of lemon (unit cost) ;

Loose lemon :

$0.99 /2 = $0.495

Bagged lemon :

$2.50 / 6 = $0.4167

Hence, since the unit cost of bagged lemon is lesser than loose lemon, then purchasing a bag of lemon is better

HOPE THIS HELPS IF NOT THEN SORRY

Step-by-step explanation:

8. ∠COB and ∠AOD are vertical angles or C

9. Vertical angles are equivalent to each other so 4x-16 = 112°

4x - 16 = 112°

4x - 16 + 16 = 112 + 16

4x = 128

4x/4 = 128/4

x= 32° or D

10. ∠AOC is vertical to ∠DOB therefore the 2 angles are congruent

You can do 360 - (112 + 112) = 2AOC

360 - 224 = 2AOC

136 = 2AOC

AOC = 68°or A

OR

You could just do 180 -112

Since ∠AOD and ∠AOC are supplementary angles, they both add up to 180°

We already know the measure of ∠AOD, it's 112°

So all you would need to do is subtract 112 from 180

And you get 68° or A

Answer:

Student's tickets: 60

Adult's tickets: 190

I think this is right

Step-by-step explanation:

"Let x represent the number of tickets sold to students under the age of 16. Let y represent those over the age of 16.

Equation 1, number of tickets sold:

The total number of tickets sold to students under the age of 16 plus the number of tickets sold to students over 16 must equal 250 (since the theater was sold out). The equation becomes:

x + y = 250

Equation 2, revenue from tickets sold.

The total revenue was $910. The cost of tickets under 16 is $2.50 and the cost of tickets over 16 is $4.00. The equation becomes:

2.50 * x + 4.00 * y = 910.00

The system of equations to solve is:

         x  +  y = 250

2.50 * x +  4.00 * y = 910.00 "

78.5in

Step-by-step explanation:

C= 2(pi)r

C= 2 x 3.14 x 12.5

C= 78.5in

Answer:

78.5

Step-by-step explanation:

To find circumference, you need to multiply radius (r) times pi (3.14 or 22/7) times 2. So, you would do 12.5 times 2 times 3.14. You would get 78.5.

Step-by-step explanation:

Answer:

Step-by-step explanation:

You first have to find 6% of 35. Which is 2.1 and so you then multiply 2.1×3 which is 6.3 and then subtract 6.3 from 35. 35-6.3 which is 28.7 and then divide that by 3. Which is essentially 9.6 if you round up the decimal. Otherwise it'd just be 9.566667. So, I'd say each is 9.6 or 10 if you're rounding for the nearest whole number.
