Answer:
<h2>1/5</h2>
Step-by-step explanation:
The sample space for pens is
5 red pens, 6 blue pens, 3 black pens,(5+6+3)= 14pens
The sample space for paper is
4 silver paper clips and 16 white (4+16)=20 papers
The probability of selecting a black pen and white paper
Pr(black pen)*Pr(white paper)
=3/14*16/20
=48/280
= 14/70
= 2/10
= 1/5
Answer:
x = -6
Step-by-step explanation:
-18 + 26 = -2(x + 2)
8 = -2x - 4
12 = -2x
x = -6
Step-by-step explanation:
A school needs 2,2337 notepads. They come in packs of 20. This is a common question.
Start by finding out how many packs of 20 go into 2,337. This is done by doing the division 2337 ÷ 20. This finds the answer 116. The remainder is 17. Hmm. The school cannot buy 116 packs of notepads otherwise they would be 17 short ( the remainder), so they buy one extra pack-117 packs. This extra pack covers the extra 17, even though there are no packs of 17, only 20. This means they will have three spare.
The answer is 117 packs.
Answer:
Answer. circumference = 151 m ( appr.) Ans :- The cost of fencing is Rs 604 .
A.) If Lucy sells 1 necklace, her sales would equal to $15.99. Then her profit would be:
Profit = $15.99 - $3.38(1) - $5.57(1)
Profit = $7.04
The fraction of the sale price of the necklace in profit is denoted as x.
15.99x = 7.04
x = 704/1559
b.) This is the same as part (a) but in decimal form. Just simply divide 704 by 1559. The answer is 0.44
c.) If Lucy's sales is $223.86 and each necklace costs $15.99, then the number of necklaces sold is $223.86 ÷ $15.99/necklace = 14 necklaces
Her profit for the 14 necklaces sold would be:
$223.86 - $3.38(14) - $5.57(14) = $98.56
