Relate ratios in right triangles

Mathematics
1 answer:
SIZIF [17.4K]2 years ago
3 0

Answer:

B

Step-by-step explanation:

Cos is the adjacent side over the hypotenuse.  The adjacent side to <E is side ED.  The hypotenuse is side EF.  ED/EF.  They do not go right out and give you this choice, but you see that B says the same thing.

Well, hopefully you know how to get Kelvin. For example. 1 degrees Celsius to Kelvin is 274.15.   Celsius - Kelvin 273.15. Anyway, two other related equations would be  x Celsius + 273.15 =  y (Kelvin) and   Celsius - Kelvin = Add 273.15

If the temperature in Celsius is 23 degrees, it would be 296.15 Kelvin. 

300 Kelvin is greater than 25 Celsius. I got my answer because I know to get Celsius, you would add 273.15 to the celsius. 25 + 273.15 = 298.15. So 300 Kelvin is greater than 25 Degrees Celsius.

I hope this helps!!

What is 5r^(2)-14r+ 8 = <br> in general trinomial
eimsori [14]

Answer:

STEP

1

:

Equation at the end of step 1

(5r2 - 14r) + 8

Step-2 : Find two factors of 40 whose sum equals the coefficient of the middle term, which is -14 .

-40 + -1 = -41

-20 + -2 = -22

-10 + -4 = -14 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -10 and -4

5r2 - 10r - 4r - 8

Step-4 : Add up the first 2 terms, pulling out like factors :

5r • (r-2)

Add up the last 2 terms, pulling out common factors :

4 • (r-2)

Step-5 : Add up the four terms of step 4 :

(5r-4) • (r-2)

Which is the desired factorization

Final result :

(r - 2) • (5r -4)

What’s the correct answer for this?
grigory [225]

Answer:

The answer is 20

Step-by-step explanation:

Reasoning it is correct because for questions like this the bottom numbers for each shape are 10 and 8 they are very close to each other on the number line there fore since the number is two off you subtract 2 and then two again since it is 2 off to get 21 the closest answer is 20

It is a little confusing but since it is two places off you subtract two twice

One side of triangle is 4 4 times the shortest side. The third side is 23 23 feet more than the shortest side. The perimeter is
jasenka [17]

Answer:

9, 32 and 36

Step-by-step explanation:

The perimeter of a triangle is the sum of all the sides.  Since you know the perimeter and the expressions for each of the sides, you can set up an equation to solve for the variable and find the values of the other sides:

one side: '4 times the shortest side' = 4s

shortest side: 's'

third side: '23 more than the shortest side' = s + 23

perimeter  = 77

Equation:  4s + s + (s + 23) = 77

Combine like terms:  6s + 23 = 77

Subtract 23 from both sides:  6s + 23 - 23 = 77 - 23 or 6s = 54

Divide by 6:  6s/6 = 54/6 or s = 9

one side: 4s = 4(9) = 36

shortest side: s = 9

third side: s + 23 = 9 + 23 = 32

18. What is the value of j in the equation √ j + √ j + 14 = 3√ j + 10? A. 16 B. √ 2 C. 4 D. 2
Rudik [331]

Answer:

  A. 16

Step-by-step explanation:

The equation can be simplified to ...

  2√j +14 = 3√j +10

  4 = √j . . . . . add -2√j -10

  16 = j . . . . . . square both sides
