We want to rewrite the given expression as a square of a monomial. We will get:

0.09*a^2 = (0.3*a)^2

So we have the expression:

0.09*a^2

We want to write this as a square of a monomial like:

(c*a)^2 = 0.09*a^2

Basically, we must find a number c such that:

c^2 = 0.09

c = √(0.09) = 0.3

Then the monomial is:

0.3*a

And we can rewrite the given expression as:

(0.3*a)^2

Answer:

16.7 percent

So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.

Answer:

6:6=x

7:16=y

8:20=z

Step-by-step explanation:

For 6, since BD is a perpendicuar bisector, that means 15x=90. Divide 90 by 15 and you get 6

for 7, if bd is a angle bisector, you can set 3y=48. divide 48 by 3 and you get 16

for 8, since Bd is a median, you can set 2z-3=z+17. Isolate the variable and you will get 2z-z=17+3. Add like terms together and you get z=20

Just so you know, a perpendicular bisector will make both angles equal to 90, an angle bisector make both angles equal to each other, and medians make it so that it hit a line in the center therefor you can set both sides of the line to be equal

Based on the length of the field and the amount of the field that was planted the fraction of the field planted is 4.1/5.

The field has a length of 25 acres and Peter plants in 20.5 acres of them.

The fraction that is planted is:

= Amount of field planted on / Total area of field

Solving will give:

= 20.5 / 25

Take to the simplest form by dividing both by 5:

= 4.1 / 5

In conclusion, the fraction planted on is 4.1/ 5.

Answer: 36/200 = 18/100 = 18%

Step-by-step explanation:

Answer:

y = $19.50

x = $17.17

z = $20.67

Step-by-step explanation:

Notice that $13.50 of $22.50 is 60% (in math decimal form 0.6). The same is true for $16.20 of $27.00. Therefore, the value of y is going to be :

0.6 * $32.50 = $19.50

We notice as well that the added taxes to the discount price $13.50 is:

14.31 - 13.5 = $0.81, which at a time is a percent of the discounted sales price. Such percentage is calculated as shown below:

0.81/13.5 = 0.06 (or 6%)

we can then add 0.06 * 16.20 = 0.972 to 16.20 to find the total price "x"that includes tax:

x = $16.20 + $0.97 = $17.17

And we do something similar to find z:

z = $20.67

Answer:

y=5

x=30

Step-by-step explanation:

the triangle with all congruent angles is an equilateral triangle, which means all side and angles are congruent, so 8y has to equal to 40 by dividing 40 by 8.

x and the angle about forms a complementary angle, so it has to be 30 degrees to add up to 90.

Answer:

Shelly earned $8,960 in interest.

Step-by-step explanation:

The formula for simple interest is A=P(1+rt). For this problem, the equation is A=8,000(1+0.04x3). 8,000 is the initial balance, 0.04 is the annual interest rate, and 3 is the time in years. Following the order of operations, 0.04 multiplied by 3 is 0.12. 0.12 plus 1 is 1.12. 8,000 multiplied by 1.12 is 8,960.

Answer:

£960

Step-by-step explanation:

So you start of by calculating the interest for one year.

8,000 × 0.04 = 320

Because the interest rate is 4% you will write it as 0.04

And because it is simple interest, you will need to multiply 320 by 3 to get the amount of interest she will get after 3 years.

320 × 3 = 960

If you wanted the total amount of money she would have after receving the interest, you just have to add 960 to the starting amount of 8,000.

8,000 + 960 = 8,960

In this, you are assuming that she doesn't take any money out or put any money in for those 3 years.

I think that's right anyway.
