Convert 52°C to degrees Fahrenheit.
Nady [450]

52°C is equal to 125.6 degrees Fahrenheit.

Given that 52°C  it should be converted into degrees of Fahrenheit.

The celcius is represented by the letter C

And the degree Fahrenheit is represented by F

The formulas for the conversion are given by  C=\frac{5}{9} (F-32)

and F=\frac{9}{5} C+32

Here the given is  52°C and we convert this to  Fahrenheit by using the formula F=\frac{9}{5} C+32

We have a C value is 52

By substituting the C value in the formula we get the F value

  F=\frac{9}{5} C+32\\F=\frac{9}{5} (52+32)\\F=\frac{9}{5} (84)\\F=125.6

Hence 52°C to degrees Fahrenheit is 125.6

An artisan wants to split his equilateral triangular-shaped piece of glass into four equally sized pieces as part of a window de
jeka94

The triangle QPR having inscribed triangle STU will allow the artisan to divided his glass piece into four equal triangular pieces.

In order to divide an equilateral triangle into four equal triangular glass pieces, the artisan must;

  • Take S as the mid-point on PA, T as the mid-point on PR, and U as the mid-point on QR. Thus, S, T, and U are the three mid-points on each side of the equilateral triangle QPR.
  • Now, by joining these mid-points S, T, and U, four equal triangles are made(as shown in the figure).

Since the triangle is equilateral,

PQ = QR = RP

Mid-point divides the lines into equal parts. So,

PS = SQ = QU = UR = RT = TP

Thus, it is proved that

ΔPST = ΔSTU = ΔTUR = ΔQSU

Flura [38]

Answer:

  • 2/3

Step-by-step Solution:

Simply change the denominators such that both denominators are the same. Then, add the fractions to get your result.

  • 1/2 + 1/6
  • => 3 x 1/2 x 3 + 1/6
  • => 3/6 + 1/6
  • => 4/6 = 2/3

Hence, the solution is 2/3.

FrozenT [24]

Answer:

$74.96

Step-by-step explanation:

$79.80 × 0.12 = 9.576 (discount)

$79.80 - $9.576 = $70.224

$70.224 × 0.0675 = 4.74012 (add for sales tax)

$70.224 + $4.74012 = $74.96412

What is the correct evaluation of 4x2 + 4x - 2y2 +3y, when x is equal to -2 and y is equal to 3?
____ [38]

Answer:

-1

Step-by-step explanation:

This all comes down to the substitution. I am assuming that (4x2) is meant to be 4x^2 so I will solve as that.

4(-2)^2 = 4(4) = 16

4(-2) = - 8    

-2(3)^2 = -2(9) = -18

3(3) = 9

16-8-18+9= -1
