please help with 6-8 ! will give brainliest !! :)

Answers

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

Rewrite that with distributive property for crown!!!

Answers

Answer:

90 + 72 -> 162

Step-by-step explanation:

15 times 6 equals 90 and 12 times 6 equals 72, the distributive property equation is 90 + 72 in which can be added to 162 as a result.

Hey there!

The formula is: a(b + c) = a(b) + a(c) = ab + ac

“6(15 + 12)”

6(15 + 12)

6(15) + 6(12)

6(15) = 90

6(12) = 72

NEW EQUATION: 90 + 72

ANSWER: 90 + 72 = 162 ☑️

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.

Shelly deposited $8,000 into a savings
account that earns 4% simple interest.
How much interest did she earn after
three years?

Answers

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.

Peter has a 25 acre field. He 20.5 acres with sweet corn . What fraction of his field does Peter plant with sweet corn

Answers

Answer:

82%

Step-by-step explanation:

Multiply 25*4 to get 100.

Then multiply 20.5*4 because what you do to one side you have to do for the other.

You end up with 0.82 or 82%

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.

Rewrite the expression as square of a monomial.

EXTRA POINTS!!!

Answers

Answer:

Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.

0.3

Step-by-step explanation:

Brainliest?

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:

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

you are rolling a die number 1-6. What is the theoretical probability that you roll a 6?

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.
