your total would be $10 and you have 1 variable. so it would be ($2x) for the pounds of veggies, plus the 3.50 for the basket, equals $10. then solve for X from there
Answer:
8. 504ft²
9. 4970yd² (rounded to 3 s.f.)
Formulas (For easy reference):
Area of rectangle = length × breadth
Area of circle = pi×r×r
Circumference of circle = pi×r×2
-----------------------------------------------------------------------------------------------------------
Step-by-step explanation:
8. You know a box has 6 sides, and there are 3 types of surfaces that are different from each other, and you have to multiply each side by 2 cus there are the front and backside (You can draw the box with its dimensions to see the 3 types of surfaces and why I multiplied by 2):
(2×12×6) + (2×12×10) + (2×6×10) = 144 + 240 + 120
= 504ft²
9. The net of a cylinder contains two circles of radius 24yd and one long sheet to wrap around the circles with the length that is the circumference of the circle (so that it can wrap around the two circles) and a width which is the height of the cylinder (9yd).
2 Circles = 2×pi×24×24
= 1152pi
Long sheet = 9×24×2×pi
= 432pi
Now we can add all of them together:
432pi+1152pi = 1584pi
= 4970yd² (rounded to 3 s.f.)
<span>Simplify both sides of the inequality.
x-5>25
</span><span> Add 5 to both sides.
</span>
x-5+5>25+5
x>30
The mode is the value that appears more often in a dataset. In your dataset, you have two 6's, two 9's and two 14's.
So, there is no value that is repeated more than any other.
In those cases, some say that your dataset has no mode. Others say that your dataset has three modes: 6, 9 and 14.
It's really all about definition, so it depends on which convention your book/course/professor sticks to.
So if we have 52 cards it would be easy to check the odds with a formula, here is the procedure:
<span>P(Ace) is 4/52 = 1/13
P(Spade) is 13/52 = 1/4
P(Ace and Space) = 1/52
therefore P(Ace or Spade) = 1/13 +1/4 - 1/52 = 4/13 =</span><span>0.30769230769230769230769230769231. that is the probability</span>
