Answer:

Step-by-step explanation:

the measure of the angle= 47-27=20

since it is a square all sides are equal

A=a*a=36

length=width=6

perimeter 2L+2W=12+12=24

Answer:

See step-by-step explanation

Step-by-step explanation:

16. C, <AOB = 20

The total angle (<AOC) is equal to the sum of the angles inside of it (<AOB and < BOC).

<AOC= <AOB + <BOC

47=<AOB+27

<AOB=20

17. 24

Area of a square = s^{2}

36= s^{2}

s= 6

One side is 6

The perimeter of a square is 4(s)

4(6) = 24

Word of encouragement:

Good luck!

If 11250 = m(600) + b and 7650 = m(400) + b, how do I find the values of b and m? I forgot how to compare when I have two differ
Lelu [443]

Answer:

b=450 and m=18

Step-by-step explanation:

This exercise is an example of <em>linear system equations</em>. A <em>system of linear equations</em> is a set of (linear) equations that have more than one unknown. The unknowns appear in several of the equations, but not necessarily in all of them. What these equations do is relate the unknowns to each other.

The easy way to solve this problem is by using the<em> reduction method</em>.The <em>reduction method</em> consists of operating between the equations, such as adding or subtracting both equations, so that one of the unknowns disappears. Thus, we obtain an equation with a single unknown.

Ordering the equations as a system equations.

\left \{ {{600m+b=11250} \atop {400m+b=7650}} \right.

Using the reduction method, let's substract the second equation with the first equation, in order to clear m.

600m + b = 11250

<u>-400m -  b = -7650</u>

200m       = 3600    -------->  m = 3600/200 -----> m = 18

We can substitute the value of m in any of the two equations to obtain the unknow b.

Let's substitute the value of m in the second equation.

400(18) + b = 7650

7200 + b = 7650 -----> b = 7650 - 7200 -------> b = 450

We can check this values in both equations.

600m + b = 11250 -----> 600(18) + 450 = 11250

400m + b = 7650 ----->  400(18) + 450 = 7650

Satisfying the result of both equations.

Can someone help me with these two questions?The last answer choice is 90 degrees.
gizmo_the_mogwai [7]

For the first one:

The radian of 60º is 1.047. you just have to find one that has the same value, which would be \pi/3. (the last choice).

for the second one:

you do it the other way. The answer is 45 degrees.
