(PLEASE ANSWER FOR BRAINILEST ASAP!!) (EXPLAIN!!) 3 boxes all way the same amount. All together they weigh 54.3 pounds. How much does 1 box weigh?

Answers

Answer 1
One weighs 18.1 pounds.
Answer 2

Answer:

Step-by-step explanation:

Let B = the weight of box B

Let 2B = the weight of box A

Let 2B + 30 = the weight of box C

B + 2B + 2B + 30 = 640

5B = 610

B = 122 pounds, weight of box B

2B = 2(122) = 244 pounds, weight of box A

2B + 30 = 2(122) + 30 = 274 pounds, weight of box C

Answers

Answer:

1 - sec (x)

Step-by-step explanation:

Write the problem as a mathematical expression

tan (x) (cot(x)−csc(x)

Apply the distributive property

tan (x) cot(x) +tan (x) (−csc(x)

Rewrite in terms of sines and cosines, then cancel the common factors

1+tan (x) (−csc(x)

Then u get 1 - sec (x)

Answers

Answer:

a=82

b=119

c=108

d=171

e=60

Step-by-step explanation:

since we can see the figure has 5 sides we can use the interior angle formula 180(n-2) and replace n for 5 getting 180(3) which woukd get us to 540. with this information we know that all the verticals have to equal 540 so we can add the equations together to get

16x+44=540 - subtract 44 from both sides to get x by itself

16x=496 - simplify

x=31

substitute x for 31 in the equations.

Answers

Answer:

6. x = 15

7. JL = 78

Step-by-step explanation:

6. 8x - 23 = ½(10x + 44) (midsegment theorem)

Multiply both sides by 2

2(8x - 23) = 10x + 44

16x - 46 = 10x + 44

Collect like terms

16x - 10x = 46 + 44

6x = 90

Divide both sides by 6

x = 90/6

x = 15

7. MN = 5x - 16

JL = 4x + 34

MN = ½(JL) (midsegment theorem)

5x - 16 = ½(4x + 34) (substitution)

2(5x - 16) = 4x + 34

10x - 32 = 4x + 34

Collect like terms

10x - 4x = 32 + 34

6x = 66

x = 66/6

x = 11

JL = 4x + 34

Plug in the value of x

JL = 4(11) + 34 = 44 + 34

JL = 78

What is the remainder if f(x) = x4 – 5x2 - 6x - 10 is divided by x - 3?

Answers

Answer:-46

Step-by-step explanation: just took test

The remainder when f(x) is divided by (x - 3) is 8 and this can be determined by using the factorization method.

Given :

[tex]\rm f(x) = x^4-5x^2-6x-10[/tex]

The following steps can be used in order to determine the remainder if f(x) is divided by (x - 3):

Step 1 - Write the mathematical expression of the statement "f(x) is divided by (x - 3)".

[tex]=\dfrac{x^4-5x^2-6x-10}{x-3}[/tex]

Step 2 - Now, try to factorize the numerator in the above expression.

[tex]=\dfrac{x^4-3x^3+3x^3-9x^2+4x^2-12x+6x-18+18-10}{x-3}[/tex]

Step 3 - Further simplify the above expression.

[tex]=\dfrac{x^3(x-3)+3x^2(x-3)+4x(x-3)+6(x-3)+8}{x-3}[/tex]

[tex]=(x^3+3x^2+4x+6) +\dfrac{8}{x-3}[/tex]

So, the remainder when f(x) is divided by (x - 3) is 8.

Step-by-step explanation:

Pythagorean theorem :)

Answers

Answer:

A^2 + B^2 = C^2

Step-by-step explanation:

Your welcome!

Answer:

x = 13

Step-by-step explanation:

In order to solve this you need to know the Pythagorean theorem:

a^2 + b^2 = c^2

a - 1 side

b - 2nd side

c - hypoteneuse

Step 1: Find the missing side of the triangles

** Note both triangles are equal to each other as shown by the dashed line in both that signifies both sides are equal to each other, and the 90-degree angle there as well**

Solve:

17^2 + b^2 = 19^2

289 + b^2 = 361

361 - 289 = 72

√72 = √b^2

8.5 = b (approximately, to the tenth)

Step 2: Because both of the triangles are equal to each other, the missing side is equal to 8.5, but there are two of them, in order to determine x, you need to add both values together:

8.5 + 8.5 = 17  

Then you   subtract it from the base value: 31

31 - 17 = 13

Therefore, x = 13, as that is the remaining of the base.
