6.34x5.2= 32.968
I use the Latisse Method for multiplying, I don't know how to do it the regular way. If you need me to explain it I can, just ask.
I hope this helps though. (^_^)

The answer is 32.96800, you can do the equation by: stacking the numbers on top so 6.34 will be on top then put 5.2 on bottom but 5 needs to be directly under the 6 and add a 0 to the end of 5.2 so it will look like 5.20 then multiply like you would with regular multiplication and you get the answer 32.96800.

Which of the following ordered pairs is a solution of x + 1/2y = 1?

pogonyaev

(-2,6)

for example

x+1/2y=1

the ordered pair i will use is the first one. (-2, 6)

(-2) + 1/2(6)=1

from there it is a simple add/subtract and multiply/divide math problem.

1/2(6)=3

(-2) + 3 = 1

yes this ordered pair works for the solution meaning it is the answer.

Write the quadratic equation whose roots are 4 and 5, and whose leading coefficient is 4.

Umnica [9.8K]

Answer:

Answer: 4x² - 9x + 20 

Step-by-step explanation:

• General quadratic equation:

${ \rm{ {x}^{2} - (sum \: of \: roots)x + (product \: of \: roots) }}$

• sum of roots → 4 + 5 = 9

• product of roots → 4 × 5 = 20

• substitute:

${ \boxed{ \rm{4 {x}^{2} - 9x + 20 }}}$

PLS HELP SHOW ALL YOUR WORKING OUT BRAINLIEST

C = to squares diagonal length

Pythagoras theorem: a^2 + b^2 = c^2

5^2+5^2=c^2
25+25=c^2
50=c^2
square root so c would be about 7.071

Since the diagonal is less than the diameter of the circle, the square will fit inside without touching the edge

Phil Fresno worked 51.5 hours.

N76 [4]

So he makes 10.40 per hr for regular work, and time and a half for anything over 40 hrs.......and he worked 51.5 hrs

10.40 (40) = 416 for his regular hrs
51.5 - 40 = 11.5 hrs overtime......1.5(10.40) * 11.5 = 15.60(11.5) =
179.40 for his overtime hrs
for a total gross pay of : 416 + 179.40 = 595.40 <==

because he worked 40 hrs at 10.40 per hr...giving him $ 416...and he worked 11.5 hrs overtime at a rate of 15.60 per hr...giving him 179.40...for a total of $ 595.40 total gross pay
