a carpenter uses a circular saw to cut a piece of lumber at a 145 angle what is the measure of the other angle formed by the cut

1 answer:

8 0

The other angle would be 35 degrees. This is because in a straight line (the wood) there are 180 degrees and when you take away 145 (the cut) you are left with 35.

180-145= 35

I hope this helps!

Simplify the square root of 40x^4

Otrada [13]

Answer:

4 = 22

Step-by-step explanation:

Factor 40 into its prime factors

40 = 23 • 5

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

4 = 22

Factors which will remain inside the root are :

10 = 2 • 5

To complete this part of the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

2 = 2

At the end of this step the partly simplified SQRT looks like this:

2 • sqrt (10x4)

Rules for simplifing variables which may be raised to a power:

(1) variables with no exponent stay inside the radical

(2) variables raised to power 1 or (-1) stay inside the radical

(3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

(3.1) sqrt(x8)=x4

(3.2) sqrt(x-6)=x-3

(4) variables raised to an odd exponent which is >2 or <(-2) , examples:

(4.1) sqrt(x5)=x2•sqrt(x)

(4.2) sqrt(x-7)=x-3•sqrt(x-1)

Applying these rules to our case we find out that

SQRT(x4) = x2

sqrt (40x4) =

2 x2 • sqrt(10)

Simplified Root :

2 x2 • sqrt(10)

Ooooooooof I need help

snow_lady [41]

Answer:

a) x = -1 and y = -10

Step-by-step explanation:

The first part says find the value of y when the value of x is -3. Then the second part of the question is to find the value of x when the value of y is 2.

so lets solve part a)

$y=6x+8\\y=6(-3)+8\\y=-18+8\\y=-10\\\\Now\ when\ y=2\ find\ x\ \\y=6x+8\\2=6x+8\\2-8=6x\\-6=6x\\-6/6=x\\-1=x\\$

So answer to part a is x = -1 and y = -10

similarly try the other parts.

Explain the steps needed to determine the value of the ex below. Be sure to provide the correct value of the expression in your

yuradex [85]

The correct answer is -1 and 1/2.

First, you need to divide 1/2 by -4/5. To do this, you multiply 1/2 by -5/4. You will get -10/8.

Then, you add -10/8 with -2/8 to get -12/8, or -1 and 1/2.

Finished goods inventory is $197,000. If overhead applied to these goods is $72,000, and the overhead rate is 150% of direct lab

prohojiy [21]

Answer:

77,000

Step-by-step explanation:

If 72,000 is 150% of direct labor, then direct labor is 48,000 (72000/1.5)

direct labor 48000

overhead. 72000

total. 120,000

total costs: 197,000

less total above: 120,000

=material costs. 77,000

What is FJ for brainliest

Likurg_2 [28]

Hiiii i just commented but it works now!

THE ANSWER IS: 9

let the length FJ be x

since the triangles are similar, set up a ratio that matches the corresponding sides
so the longest side of the triangle over the shortest side of the triangle

set the ratios equal to each other

to solve for 16+x, multiply 15x15 then divide by x
rewrite that as 225/x = 16+x

solve for x
you’ll get two answers: -25 and 9
since the side length can’t be negative, the answer is 9
