Step-by-step explanation:

Hi,

4 (1/5 +2/3)

Find common denominators...

1/5 = 3/15

2/3 = 10/15

Add...

13/15

Now, multiply...

4 (13/15)

52/15

Simplify...

3 7/15

Hope this helped :)

The sides of △FGH are FG = 6 x+ 7, GH = 8x - 5, and FH = 10x - 11. If the perimeter of △FGH is 87, list the angles in order from

irga5000 [103]

Answer:

From largest to smallest: FG, FH, GH

Step-by-step explanation:

Given

$FG = 6x + 7$

$GH = 8x - 5$

$FH = 10x - 11$

$Perimeter = 87$

Required

Order the sides in descending order

First, we need to solve for x.

Perimeter of FGH is calculated as thus:

$Perimeter = FG + GH + FH$

Substitute values for FG, GH, FH and Perimeter

$87 = 6x + 7 + 8x - 5 + 10x - 11$

Collect Like Terms

$87 - 7 + 5 + 11= 6x + 8x + 10x$

$96= 24x$

Reorder

$24x = 96$

Divide through by 24

$x = 96/24$

$x = 4$

Substitute 4 for x in FG, GH and FH

$FG = 6x + 7$

$FG = 6 * 4 + 7$

$FG = 24 + 7$

$FG =31$

$GH = 8x - 5$

$GH = 8 * 4 - 5$

$GH = 32 - 5$

$GH = 27$

$FH = 10x - 11$

$FH = 10*4 - 11$

$FH = 40 - 11$

$FH = 29$

In order of arrangement in descending order, we have:

$FG =31$ $FH = 29$ $GH = 27$

Bob's password consists of a non-negative single-digit number followed by a letter and another non-negative single-digit number

maw [93]

9/20 is the probability that Bob's password consists of an odd single-digit number followed by a letter and a positive single-digit number

It is given that bob's password consists of a non-negative single-digit number followed by a letter and another non-negative single-digit number (which could be the same as the first one).

P (odd single digit number ) = ( 5 odd single digits / 10 non-negative single digits) = (5/10) = 1/2

P (positive single digit number ) = (9 positive single digits / 10 non-negative single digits) = 9/10

The total probability is (1/2) (9/10) = 9/20

Plz help with the math worth 21 points

Answer:

As there is one math problem over there.

Lets see the question first:

It says that "A hair dryer is rated $1200\ W$ ,if you use the dryer for $0.25\ h$ .How much electric energy do you use ?"

Final answer = Electic energy $=0.3\ kW\ h$

Step-by-step explanation:

Electrical Energy $E=Power \times time$ .

The total amount of electrical energy used depends on the total power used by the electrical device and the total time they are used for.

So we have been given the power of the hair dryer $=1200\ W =\frac{1200}{1000}=1.2\ kW$

Now the time it has been use for $=0.25\ hrs$

To calculate electric energy we will multiply both the terms.

Electric energy $=0.12 \times 0.25 =0.3\ kW\ h$

So electric energy used for the hairdryer is = $0.3\ kW\ h$
