Mr. Sonny's science class is calculating the average number of blinks per minute. Jan blinks 126 times in 7 minutes. What is her blinking rate, in blinks per minute?

Answers

Answer 1

18 blinks per min since 126 divided by 7 equals 18

Answer 2

Answer:
b. Every 24 minutes
Step-by-step explanation:
A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.
The first step is to:
Find and list multiples of each time each neon sign blinks.
This means, we find the Multiples of 6 and 8
Multiples of 6:
6, 12, 18, 24, 30, 36
Multiples of 8:
8, 16, 24, 32, 40
The first and common multiple of 6 and 8.
Therefore, the Least common multiple [LCM(6, 8) ] = 24
Hence, they often blink at the same time every 24 minutes.
Therefore, option b.Every 24 minutes is correct.

George is putting trim around his rectangular deck, including the gate. He will need 46 feet of trim to do the entire deck. If the deck is 15 feet long, how wide is the deck?
A.
6 feet
B.
16 feet
C.
8 feet
D.
23 feet

Answers

Answer:

C: 8 feet

Step-by-step explanation:

You have to find the parameter.

To do that you add all the side lengths together.

15+15=30 now you have to subtract 30 from 46 to find how much room is left.

46-30=16 now divide your answer by 2 to get the 2 remaining sides of the deck.

16/2=8 so the answer is 8!

What type of triangle is this triangle?

acute scalene

obtuse isosceles

obtuse scalene

acute isosceles

Answers

Answer:

Obtuse scalene

Step-by-step explanation:

Answer:

obtuse scalene

Step-by-step explanation:

Scalene means that none of the sides are equal.

Isosceles means that two of the sides are equal.

Obtuse means an angle in the triangle is larger than 90 degrees.

Acute means all angles in the triangle are smaller than 90 degrees.

None of the sides are equal so this triangle has to be scalene and the angle in the bottom right is larger than 90 degrees so this triangle is obtuse.

Hope this helps! :)

Hello, I would really like some help on this!! Please leave an explanation of how you got your answer! Thank You!

Answers

1a) To find the total area, you must find the area of the triangular part that is missing, then subtract this from the area of the rectangle. For the triangle’s area, you need to know the width (2m) and length (2m). For the rectangle’s area you need to know the width (3m) and length (4m).
1b) the total area is 10m^2 (10 meters squared). This is found by subtracting the triangle (.5x2x2=2) from the rectangle (3x4=12).

(-aⁿ)ᵒᵈᵈ = -aⁿ

(-aⁿ)ᵉᵛᵉⁿ = aⁿ

aⁿ × aⁿ = aⁿ⁺ⁿ

_________

In this situation, 6 is an even exponent which means that the negative coefficient of this 9th degree monomial will be positive. Now the only step is to multiply the exponents by the exponent outside of the perenthesis which is 6.

so (-a³b⁴c⁹)⁶ = ((-a³)⁶(b⁴)⁶(c⁹)⁶) = ((a³ˣ⁶)(b⁴ˣ⁶)(c⁹ˣ⁶)) = ((a¹⁸)(b²⁴)(c⁵⁴)) = a¹⁸b²⁴c⁵⁴
