What kind of angle is each internal angle of a Square

2 answers:

8 0

For a square, the inner angles will all be Right Angles, meaning they have a measure of 90°. This is because all 2D shapes have an inner angle measure of (n-2)180° where n is the number of sides and all 4 angles of a square are equal.
This means that the measure of each angle in a square is:
$(4-2)180 =4x\\
x=\frac{(2)180}{4}\\
x=90$
Thus each inner angle has a measure of 90°.

Kristen invests $5,745 in a bank. The bank pays 6.5% interest compounded monthly. How long must she leave the money in the bank

s344n2d4d5 [400]

formula is $A=P(1-\frac{r}{n})^{nt}$

where A=final amount

P=principal

r=interest rate in decimal

n=number of times per year it is compounded

t=time in years

we want to find where

A=2P

and P=5745

and r=6.5%=0.065

n=monthly=12

remember that $ln(x^a)=a(ln(x))$

also that $(a^b)^c=a^{bc}$

$2(5745)=5745(1+\frac{0.065}{12})^{12t}$ , solving for t

divide both sides by 5745 to simplify things a bit

$2=(1+\frac{0.065}{12})^{12t}$ I'd rather not simplify this because it give us a decimals and those aren't exact, if we combine, we get 12.065/12 for inside parenthases

$2=(\frac{12.065}{12})^{12t}$

take ln of both sides

$ln(2)=ln((\frac{12.065}{12})^{12t})$

$ln(2)=(12t)ln(\frac{12.065}{12})$

divide both sides by $12ln(\frac{12.065}{12})$

$\frac{ln(2)}{12ln(\frac{12.065}{12})}=t$

using our calculator, t≈10.6927

so rounded, we get 10.7 years

Please help with number 33 and 34!

Problem 33

For each number, generate a factor tree. This is where you break a number down into smaller factors in a visual "tree" like style. The idea is to factor down to the prime factors and then you circle the common primes between each number. The values you circle are then multiplied if you circle more than one value in each tree.

-------------------------------------------------------------------------------

Problem 34

Xiao factored correctly but didn't pull out the GCF. So he didn't factor fully. In the case of 60 and 90, the GCF is 30. This is the largest shared factor between the two values. So we can pull out 30 to get
60+90 = 30*2+30*3 = 30*(2+3)

I'm basically using the distributive property in reverse. You can distribute the 30 back in and get 60+90 again. Notice how the inner stuff 2 and 3 have no factors in common other than 1.

A system of equations is graphed on the coordinate plane.

ANTONII [103]

You have 2y=3x-1 and 4y=6x-2. first step is to get the y by itself . first equation you divide everything by 2 which gives you the equation: y= 3/2x-1/2
or y= 1.5x-.5, for the second equation you divide everything by 4, which gives you y=6/4x-2/4 (1/2) or y=1.5-.5. both equations are equal to one another:
the answer is therefore C Infinitely many solutions.
