$27.55
29.95 x 8% (aka .08) = 2.396
29.95- 2.396 = 27.55
Suppose an astronaut on the moon drops a tool. How long
does it take the tool to fall 4 feet?
Answer:
3/2
Step-by-step explanation:
If d = feet and the question is how long it takes if a tool falls down 4 feet then plug that in the equation, which is 4 = 8/3 t
Then bring the 3 to the other side by multiplying which is 8x = 12
Lastly it is 12/8, simplified to 3/2
The astronaut's tool would take 1.5 seconds to fall 4 feet on the moon when using the given function d(t) = 8/3 t.
To find the time it takes the tool to fall 4 feet on the moon, we would need to set the distance d equal to 4 in the given mathematical expression and solve for t. So we would use the given function d(t) = 8/3 t.
So the astronaut's tool would take 1.5 seconds to fall 4 feet on the moon.

running at the same rate?
We want to create a proportion with minutes over miles for each person. The proportion for this problem is shown below.
30 minutes / 4 miles = 56 minutes / 7 miles
To find out if these people are running at the same rate, we can cross-multiply.
224 = 210
Because 224 and 210 are not equivalent, the people are not running at the same rate.
Hope this helps!! :)
-6+{14+2 [60 – 9(1+3)]}
Enter your answer in the box.
Answer:
56
Step-by-step explanation:
To simplify the given expression, solve the innermost parentheses first, followed by simplifying the expression within the brackets, and finally performing addition. The simplified expression is 56.
To simplify the given expression, we need to follow the order of operations (PEMDAS/BODMAS). In the given expression, we start by solving the innermost parentheses first:
9(1+3) = 9(4) = 36.
Then, we simplify the expression inside the brackets:
[60 - 36] = 24.
Finally, we substitute the value of the simplified expression back into the original expression:
-6 + {14 + 2 × 24} = -6 + {14 + 48}.
Further simplification within the brackets:
-6 + {62}.
And finally, performing the addition:
-6 + 62 = 56.
Therefore, the simplified expression is 56.
