In the diagram below DE is the midsegment of AABC.
Find the length of DE and BC.

Answer:

3.13

Step-by-step explanation:

Because the 4 is in the hundreds place. The rule for the number would be less than five so round down. 4-1=3.

The value of π to the nearest hundredth is 3.14.

Place value, which is related to a digit's location in a number, is the amount that each digit is worth.

Given:

An equation,

π = 3.14

To round off the number to the nearest hundredth:

The digit at the hundredth place in decimal is 4.

And the left to the digit is 3.

The number 4 is less than the number 5.

So, there will be no changes in the approximation of the decimal number.

So, π = 3.14.

Therefore, the value is π = 3.14.

Answer:

The solution is (15, 11)  There is only one solution.

Step-by-step explanation:

Solve this system using substritution.  In the second equation replace x with 2y - 7, obtaining:

4(2y - 7) + y = 71, which simplifies as follows:

8y - 28 + y = 71, or

9y = 99.  then y must be 11.  If y is 11, then x = 2y - 7, or x = 2(11) - 7 = 15

The solution is (15, 11)  There is only one solution.

Answer:

Step-by-step explanation:

Since we are not given actual numerical values then we can use the available information to write an equation that calculates the final amount in the account on Friday (f). In this equation, x will be our variable that represents the amount of money in the account on Tuesday. Since the amount on Tuesday was 4 times more than on Friday, we need to divide the amount on Tuesday by 4 to get the amount on Friday.

f = [tex]\frac{x}{4}[/tex]

This equation will give us the value of the account on Friday after we input the value of x.

Answer:

19 years approx

Step-by-step explanation:

Given data

Principal P= $4400

Rate r=7%

Final amount A=$10100

Time t= ???

Let us apply the simple interest expression

A=P(1+rt)

substitute

10100=4400(1+0.07*t)

open bracket

10100=4400+308t

10100-4400=308t

5700=308t

t= 5700/308

t= 18.50

Hence the time is 19 years approx

i don't know english very well so i don't knoe what transplant is but i think i got it right with my logic

Answer:

m∠1 = 136°

m∠2 = 44°

m∠3 = 136°

m∠4 = 44°

m∠5 = 136°

m∠6 = 44°

m∠7 = 136°

Step-by-step explanation:

Corresponding angles, like m∠1 and m∠5, need to equal each other.

m∠1 and m∠3 are the same

m∠3 and m∠2 need to be added together to equal 180

Answer:

13122

Step-by-step explanation:

6 x 3 = 18; 18 x 3 = 54; continue to do this 8 times and you get 13122!

Answer:

a(8) = 6*3^7 = 13122

Step-by-step explanation:

Each new term is equal to the previous one times the common ratio, r, which in this case is 3.

The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1).

In this particular case, we have a(n) = 6*(3)^(n -1).

The 8th term of this sequence is a(8) = 6(3)^(8 - 1), which works out to:

a(8) = 6*3^7 = 13122

Answer:

20 m

Step-by-step explanation:

Given :

Leveling cost per square meter = 15

Total leveling cost = 6000

Number of square park leveled :

Tottal cost / unit cost

6000 / 15

= 400 m²

The length of one side of the square

Area of square = s²

where, s = side length

400 = s²

Sqrt(400) = s

s = 20 m

Length of one side = 20 m

Answer:

3s+2p= $120

each shirt is $15

3(15)+2p= $120

45+p=120

p= $75
