Answer: 3/8, 0.375, 37.5%
Step-by-step explanation:
Count the number of cards with odd numbers that are greater than 4. 5, 7, and 9 are odd numbers greater than 4. There are 3 cards with odd numbers greater than 4. Probability is found by dividing this by the total number of cards, 8. This gets you a fraction of 3/8.
Answer:
solution 1= 40ml
solution 2= 160ml
Step-by-step explanation:
%alcohol= amount of alcohol/total solutionx100
0.52x200=104ml of alcohol present
0.2x L=0.2Lml of alcohol in solution one
0.6 x M=0.6Mml of alcohol in solution two
1st equation
0.2L+0.6M=104ml alcohol
times 10 to get whole
2L+6M=1040ml
2nd
same for this equation
10L+10M=2000ml
10L+10M=2000
2L+6M=1040
elimination method
=20L+20M=4000
-
=20L+60M=10400
-40M=-6400
M=160ml
2L+6 (160)=1040
2L=1040-960
2L=80
L=40ml
145=10x-8x it’s A I’m pretty sure

<h3><u>Question:</u></h3>
The rectangle below has an Área of x^2 + 11x + 28 square meters and a length of x+7 meters. What expression represents the width of the rectangle?
<h3><u>Answer:</u></h3>
The expression representing width of rectangle is (x + 4) meters
<h3><u>Solution:</u></h3>
Given that rectangle has an area x^2 + 11x + 28 square meters and a length of x + 7 meters
To find: width of the rectangle
<em><u>The area of rectangle is given as:</u></em>

Here area = x^2 + 11x + 28 square meters
length = x + 7 meters
<em><u>Substituting the values in given formula,</u></em>

Cancelling (x + 7) on numerator and denominator,

Thus expression representing width of rectangle is (x + 4) meters
