I need help with an explanation

Answer:34.3 N and 15.7 N

Explanation:

 = force on the left end of the rod

 = force on the right end of the rod

M = mass of Halloween decoration = 3 kg

 = weight of the Halloween decoration = Mg = 3 x 9.8 = 29.4 N

m = mass of rod = 2.1 kg

 = weight of the rod = mg = 2.1 x 9.8 = 20.6 N

From the force diagram, using equilibrium of torque about A

(AB) +  (AC) =  (AD)

(29.4) (21) + (20.6) (57) =  (114)

 = 15.7 N

Using equilibrium of force along the vertical direction

+  =   +

15.7 +   = 29.4 + 20.6

= 34.3 N

Answer:

1,250 curtain rods

Step-by-step explanation:

2500 + 3750 = 6250

6250/5=1,250

1,250 curtain rods

(If one square on the graph = one centimeter)

b = 10cm

b = 10cmh = 10cm

Area:

[tex] = \frac{1}{2} \times b \times \: h[/tex]

[tex] = \frac{1}{2 } \times 10 \times 10[/tex]

[tex] = \frac{1}{2} \times 100[/tex]

Answer:

c would be the closest

Step-by-step explanation:

All triangles equal 180*. so if you combine the 2 angles, which adds up to 77* then that would leave the third angle to be 103* but since that isnt an option choose c since its the closest.

3 is the ans

9514 1404 393

Answer:

Step-by-step explanation:

The x-terms are the same in each equation, so subtracting one equation from the other will eliminate the x-variable.

The y-terms are opposites in the two equations, so adding the two equations will eliminate the y-variable.

Both strategies (subtracting, adding) are applicable to this system of equations.

Have a safe and happy new years

Step-by-step explanation:

Answer:

Step-by-step explanation:

The first step here is to use the distributive property to make the first equation back into a polynomial.

The way we do this is by multiplying each term on the inside of the parentheses by the -2 on the outside.

-2 x x = -2x

-2 x 3 = -6

So, our new equation reads: -2x - 6

-2x - 6 = -2x + 3 - 9

Our next step is to subtract the 9 from 3.

-2x - 6 = -2x - 6

We add 6 to each side

-2x = -2x

x = x

0 = 0

=================================================

Explanation:

Check out the image below. I've posted the synthetic division table. The value at the very end of the bottom row is the remainder. By the remainder theorem, this is exactly the value of g(-5).

Recall the remainder theorem says: If you divide p(x) by (x-k), then the remainder is p(k). In this case, k = -5 is our test root which is the value placed in the box on the left.

As a way to check the answer, we can say

g(x) = 2x^2 + 6x + 5

g(-5) = 2(-5)^2 + 6(-5) + 5

g(-5) = 25

So the answer is confirmed.

Answer:

45

Step-by-step explanation:

Answer:

a = 45

b = 15

Step-by-step explanation:

From the information given, you can deduce that both ΔPQR and ΔPSR are isosceles triangles that share base PR. This means that ∠a = ∠SRP because the base angles of an isosceles triangle are always congruent.

Because the vertex of ΔPSR is 90°, you know that the base angles add up to 90 because 180(sum of a triangle's angles) - 90 = 90. 90/2 = 45, so a = 45.

To find b, you need to subtract the base angle of ΔPSR from the base angle of ΔPQR. ΔPQR's base angle is 60, because 180 - 60 = 120 and 120/2 = 60. 60 - 45 = 15, so b = 15.

Но звезда, что высоко в небе, по-прежнему показывает мой путь.

Step-by-step explanation:

Answer:

(0,0) , (a,b) , (2a,2b) is the answer

Step-by-step explanation:

for a triangle to be isosceles, then two sides must be equal

To picture this, if we have a point at the origin, with coordinate (0,0); we can have the coordinates of the other points being the same so as to make the distance from the origin the same

Then from here, we can get that the length of the two sides are equal

From what we have, option 4 can be correct

This is because , finding the distance between two points is;

D = √(x2-x1)^2 + (y2-y1)^2

From what we have

The distance between (0,0) and (a,b) will give same answer for the distance between (a,b) and (2a,2b)

number 3. answer is 7/80

number 4. answer is 31.25%

number 5. answer is 60%

Step-by-step explanation:

hope this helps!

Answer:

1. 561%

2. 1

3. 7/80

4. 31.25%

5. 6%

Step-by-step explanation:

To start off, lets learn how to convert decimals to percent's.

Converting is actually not too hard. All you need to do is multiply the decimal by 100.

So 5.61 * 100

That would be 561 and then you add a percent sign to the end.

To convert a percent to a decimal is just the opposite of what we just did. Simply divide the percent by 100.

So 100% /100

A number divided by itself is 1

So 100% = 1

To make this problem easier, you can convert the fraction to a decimal.

8 3/4 = 8.75%

Now divide it by 100

8.75/ 100

0.0875

Now just convert it back to a fraction.

0.0875 = 7/80

Convert to a decimal.

5/16 = 0.3125

Multiply by 100

31.25

add percent sign

31.25%

Last one.

Convert to decimal

3/5 = 0.6

Multiply by 100

6%

Answer:

tan360°= 0

I hope this helps you

Answer:

please mark as brainliest

Step-by-step explanation:

tan360°

= cot (90°-360°) = cot -270°

-tan360°

= tan (-360°) = -tan 360°

= cot (90°+360°) = cot 450°

= tan (180°-360°) = tan -180°

Answer: It would be 4.8

Step-by-step explanation: Each side of a square is equal, there's 4 sides in a square, so you multiply 1.2 by 4. That should give you the perimeter.

Answer:

10a-10ab-7b

Step-by-step explanation:

i dont feel like putting the steps but ik this is correct

The answer is -4a -8ab -7b after subtracting  8b - ab + 7a from 3a - 9ab + b.

It is defined as the combination of constants and variables with mathematical operators.

We have two expressions:

8b - ab + 7a and  3a - 9ab + b

After subtracting:

= (3a - 9ab + b) - (8b - ab + 7a)

= -4a -8ab -7b

Thus, the answer is -4a -8ab -7b after subtracting  8b - ab + 7a from 3a - 9ab + b.
