Answer:

a=18.1 or √329

Step-by-step explanation:

a²+b²=c²

a²+20²=27²

a²+400=729

a²=329

a=18.1 or √329 depending on what form you are answering in, radical or decimal.

Answer:

2304 beams

1296 beams

Step-by-step explanation:

Total beams  to be used in the 9 houses = number of frames needed for a beam x total number of house frames

9 x 256 = 2304

Total beams left over = total number of beams delivered to the 9 houses - total number of beams  to be used in the 9 houses

total number of beams delivered to the 9 houses = 400 x 9 = 3600

3600 - 2304 = 1296

Answer:

Dennis's score = 104

Step-by-step explanation:

Let us represent:

Dennis's score = x

Amanda's score = y

Jorge's score = z

Three friends go bowling.​

Dennis's score is 46 points greater than​ Amanda's score.

x = 46 + y

​ Amanda's score is 70 points less than​ Jorge's score.

y = z - 70

If​ Jorge's score is​ 128

z = 128

what is​ Dennis' score?

Step 1

we solve for y = Amanda's score

y = z - 70

z = 128

y = 128 - 70

y = 58

Step 2

We solve for Dennis's score

x = 46 + y

x = 46 + 58

x = 104

Dennis's score = 104

Answer:

C. 12

Step-by-step explanation:

To change triangle PQR to XYZ you divide by 4. This can be seen in the change from 12 to 3 on the left side of the triangle. So, you divide 20 by 4 and get 5 and then divide 16 by 4 and get 4.

12/4=3

20/4=5

16/4=4

So, you add these values together to get the perimeter of 12.

Answer:

l = 9

Step-by-step explanation:

Create equations w = l - 6, A = 27, so A = l (l-6) so 27 = [tex]l^{2}[/tex] - 6l

so  [tex]l^{2}[/tex] - 6l - 27 = 0, by factoring (l-9)(l-3) = 0 so l = 9 or l = 3 since the width can't be negative then l has to be 9 so that w = 9-6 = 3, so width = 3 and l = 9

Step-by-step explanation:

Answer:

C

Step-by-step explanation: it's a negative slope, the y-intercept (b) is -1, and the rise over run is -4/1

answer:

**the answer is the picture**

i plotted the dots in the order they're in on the chart

(the x axis is the time and the y axis is the distance)

so you would plot (1,4) which is the equivalent to time=1 distance=4

next (2,8) then (3,12) and lastly (4,16)

good luck :)

hopefully, this helps

**i tried my best**

have a great day !!

Answer:

The equation is (x-1)*2 + (y + 4)*2

Answer: $467.21

Step-by-step explanation:

8% of 600 = 48

600 - 48 = 552

8% of 552 = 44.16

552 - 44.16 = 507.84

8% of 507.84 = 40.6272

8% of 507.84 ≈ 40.63

507.84 - 40.63 = 467.21

Answer:

x=3

Step-by-step explanation:

1st distribute

8x-6-8=4+2x

2nd add

8x-14=4+2x

3rd move like terms

8x-2x=4+14

4th add the numbers

6x=18

5th divide both sides by 6

6x/6=18/6

x=3

Answer:

B. One

Step-by-step explanation:

There is one solution for the given system. The correct answer would be an option (B).

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

The system of equations is given in the question, as follows:

x + 2y = 10   ....(i)

2x + 8y = 16 ....(ii)

From equation (i),

x + 2y = 10

x = 10 - 2y   .....(iii)

Substitute the equation x = 10 - 2y in the equation (ii), and solve for y

Then we get the value of y  = -1

Substitute the equation y  = -1 in the equation (iii), and solve for x

So we get the value of x = 12

Thus, there is one solution for the given system.

Answer: I believe it is (2)3

Step-by-step explanation:

Answer:

the correct answer to your question is A:38

Step-by-step explanation:

this math is pretty basic, all you have to do is subtract 90-54 and you get 38.

the angle you are working with is a 90 degree angle and it gives you one part of the whole angle that is split into two parts. one part is 54 and the other is 38 making 90.
