Write it out like so..
Small
A = lw
Large
A = (2l)(2w)
A = 4(lw)
Ratio is 4:1

4 0
A=L*W
A=(21)*(2w)=4*L*W
you are comparing 4lw to 1lw
the ratio is 4 to 1 or 4:1 or 4/1

What's the degree of x^2+9x-8
marishachu [46]

Answer:

2

Step-by-step explanation:

The degree of a function is the highest power any single term is raised to.

x^2 is the term that has the highest degree, so in this case, the degree is 2.

For example; in x^5-x^4-3x^3; the degree would be 5 because the highest power x is raised to is 5.

Find all angles and pls show steps ​
Ghella [55]

Answer:

Both angles have a measure of 134degrees, y = 27degrees.

Step-by-step explanation:

As per what is given in the problem:

There are 2 parallel lines, both are intersected by a transversal.

Remember the theorem, when two parallel lines are intersected by a transversal, then the alternate exterior angles are congruent.

The is meanse that:

3y + 53 = 7y - 55

Solve using inverse operations:

3y + 53 = 7y - 55

     +55         +55

3y + 108 = 7y

-3y            -3y

108 = 4y

/4      /4

27 = y

Now, substitute back in to find the value of the angle:

3y + 53

y = 27

3 ( 27 ) + 53

81 + 53

= 134

Since the angles are alternate exterior, they are congruent, hence both angles have a measure of 134degrees.

Step-by-step explanation:

Solve for radius first using the equation for circumference:

C = 2πr

44 = 2πr

44/2π = r

r = about 7 cm

d = 2r

d = 2*7
