Answer:

15.38% or 0.1538

To know:

[] There are 4 cards that are 8s in a standard 52-card deck

[] There are 4 aces in a standard 52-card deck

Step-by-step explanation:

[] Wanted outcomes divided by possible outcomes

4 + 4 = 8 wanted outcomes

52 possible outcomes

8 / 52 ≈ 0.1538

[] Converting to a percentage

0.1538 * 100 = 15.38%

Have a nice day!

The perimeter of a kite is 50 mm. The length of one of its sides is 1 mm more than twice the length of another. Find the length

rosijanka [135]

Answer:

The length of the longest side is 13mm

Step-by-step explanation:

Represent the two sides with a and b, where a is the longest

$Perimeter = 50$

$a=b + 1$

Required

Determine the length of the longest side

Perimeter of a kite is calculated as thus:

$Perimeter = 2(a + b)$

Make b the subject in $a=b + 1$

$b = a -1$

Substitute a - 1 for b and 50 for Perimeter in $Perimeter = 2(a + b)$

$50 = 2(a + a - 1)$

Divide through by 2

$25 = a + a - 1$

$25 = 2a- 1$

Add 1 to both sides

$25 + 1 = 2a - 1 +1$

$25 + 1 = 2a$

$26 = 2a$

Solve for a

$a = 26/2$

$a = 13$

Hence, the length of the longest side is 13mm

Combine like terms to create an equivalent expression 2s+ (-4s) pls help

pav-90 [236]

The equivalent expression to $2s + (-4s)$ is $-2s.$

Step-by-step explanation:

Step 1:

In sums like these, it is easier to take the common term out of the simplification.

In the expression $2s + (-4s)$ , the common term between $2s$ and $-4s$ is the term s. So we take the term s as the common factor.

So taking s out of $2s + (-4s)$ we get $s (2+(-4)).$

Step 2:

If we multiply a positive with a negative we get a negative. S0 $+(-4) = -4.$

$2s + (-4s) = s (2-4) = s(-2) = -2s.$

So the equivalent expression to $2s + (-4s)$ is $-2s.$
