Step-by-step explanation:

The sum of two opposite interior angles equals one exterior angle

111°=60°+‹G

‹G=111°-60°=51°

We use the same property above

3x+4x+5=68°

7x=68-5

7x=63

x=63/7=9

‹D=4(9)+5

‹D=41°

Brittany opened a savings account with an annual interest rate of 10% and an initial deposit of $7000. If her interest is compou

GenaCL600 [577]

Initial Deposit = $7000

It means P= $7000

rate of interest = 10%

So , r = 0.10

compounded quarterly , so n = 4

and we have to find the amount after 5 years , So t = 5

Now the formula we use here is

$A= P(1+\frac{r}{n} )^{nt}$

$A= 7000(1+\frac{0.10}{4} )^{(4)(5)}$

$A= 7000(1.025 )^{(20)}$

$A= 7000(1.63861644029)$

$A= 11470.315$

So amount after 5 years = $11470.315

Is (x + 1) a factor of 10x^3 - 15x^2 + 7x + 32?

iragen [17]

$10x^3-15x^2+7x+32^{}=0$

we can divide the equation on (x+1) and if we have a real solutons (x+1) is a factor

is a factor because the remainder is 0

so the new form of the equation is

$(x+1)(10x^2-25x+32)$

A rectangular poster is 3 times as long as it is wide. A rectangular banner is 5 times as it is wide. Both the banner and the po

Svetradugi [14.3K]

The length and width of poster are 9 inches and 3 inches respectively and length and width of banner are 10 inches and 2 inches respectively

<u> Solution:</u>

Given, A rectangular poster is 3 times as long as it is wide.

Rectangular banner is 5 times as long as it is wide.

Both the banner and the poster have perimeters of 24 inches

Let, the width of poster be p, then its length will be 3p

And, the width of banner be b, then its length will be 5b

Now, according to given information,

Perimeter of poster = 24 inches and perimeter of banner = 24 inches

2(length of poster + width of poster) = 24

2(3p + p) = 24

2(4p) = 24

8p = 24

p = 3

And 2(length of banner + width of banner) = 24

2(5b + b) = 24

2(6b) = 24

12b = 24

b = 2

So, width of poster is 3 inches, then length of poster is 3p = 3 x 3 = 9 inches

And, width of banner is 2 inches, then length of banner is 5b = 5 x 2 = 10 inches
