Answer:

b=121, a and c=59

Step-by-step explanation:

b and 121 are congruent angles, so they are equal to each other.

each side of a line equals 180 degrees, so subtracting 180-121=c gives you 59 degrees.

a and c are congruent angles so they are also equal to each other

Andrea's living room floor is a rectangle 12 feet by 15 feet. She wants to buy a rug that is geometrically similar to her living

Sliva [168]

Answer:

180 square feet

Step-by-step explanation:

A rug that is geometrically similar to her room floor is one that has the same size as her room floor.

The floor has dimensions 12 feet by 15 feet.

The area of the floor and hence, the rug is:

A = 12 * 15 = 180 square feet

She should buy a rug that is 180 square feet

Subtract the given function and indicate the domain of the difference

maxonik [38]

Answer:

The domain is $x\in (-\infty,\infty).$

Step-by-step explanation:

Given functions $f(x)=x^2+3x+1$ and $g(x)=2x^2-4x-1$

Subtract these two functions:

$f(x)-g(x)\\ \\=(x^2+3x+1)-(2x^2-4x-1)\\ \\=x^2+3x+1-2x^2+4x+1\\ \\=(x^2-2x^2)+(3x+4x)+(1+1)\\ \\=-x^2+7x+2$

Plot these difference on the coordinate plane (see attached diagram). This function is defined for all vlues of x, so the domain is $x\in (-\infty,\infty).$

A total investment of $10,700 is made into two savings accounts. One account yields 5% simple interest and the other 6% simple i

AlladinOne [14]

Answer:

He earn $535.00 in the 5% account

Step-by-step explanation:

$I = \frac{prt}{100}$

I = interest amount

p = $10 700

r = 5%

t = 1 year

I = (10700×5×1)/100

= $535.00
