Help <br> Im giving 10 points
NISA [10]
I’m pretty sure the answer is B) d= 3.2t

Because 3.2 is basically 3.20. And 3.20 is basically 320. If you subtract that by the distance, it would be less than 320.

I think this is the answer but if it isn’t I’m sorry. But I think it is B

The equation for this problem would be a=97-4*2

So, 97-4=93, and 4 * 2=8 so 93+8= 101

So he had 101 chocolate bars at first.

Which number is larger? Justify your answer -4.03 or -4.3
Arada [10]
The larger number will be -4.03

For negative numbers, I like to sort of think backwards as I would when looking at positive numbers. For example:
+4.3 > +4.03
But when it is negative it will be the opposite!
-4.3 < -4.03

The “larger” the negative may seem, the smaller it actually is! Think of it on a number line!

Hoped this helps you out! Have a good day!

A and B are independent events. P(S) = 0.40 and P(B) = 0.30. What is P(A and B)
n200080 [17]

The value of the probability P(A and B) is 0.12

<h3>How to determine the probability?</h3>

The given parameters are

P(A) = 0.40

P(B) = 0.30

Given that the events are independent events;, we have:

P(A and B) = P(A) * P(B)

So, we have:

P(A and B) = 0.40 * 0.30

Evaluate

P(A and B) = 0.12

Hence, the value of the probability P(A and B) is 0.12

Math help please show work thanks

Problem 5

d = 29 = diameter

r = d/2 = 29/2 = 14.5 = radius

SA = surface area of sphere

SA = 4*pi*r^2

SA = 4*pi*(14.5)^2

SA = 841pi

SA = 841*3.14

SA = 2,640.74 square inches

To convert from square inches to square feet, we divide by 144. This is because 12^2 = 144.

2,640.74 square inches = (2,640.74)/144 = 18.3 sq ft

<h3>Answer: 18.3 square feet (approximate)</h3>

=====================================

Problem 6

d = 10.7 = diameter

r = d/2 = 10.7/2 = 5.35 = radius

L = 22.3 = slant height

SA = surface area of the cone

SA = pi*r^2 + pi*r*L

SA = pi*(5.35)^2 + pi*5.35*22.3

SA = 147.9275pi

SA = 147.9275*3.14

SA = 464.49235

<h3>Answer:  464.49235 square cm (approximate)</h3>
