1)88 2)44.5

Step-by-step explanation:

i'm not sure about 3 and 4

Answer:

1.) 88cm²

2.) 44.5cm²

3.) 141.37cm²

4.) 44cm²

Step-by-step explanation:

Alrighty, we're just going to do an abridged version, but if you need me to explain it more, I can:

1.) 6 x 8 ÷ 2 = 24

8 x 8 = 64

64 + 24 = 88

1.) 88cm²

2.) 2 + 2 + 3 = 7

7 x 5 ÷ 2 = 17.5

9 x 3 = 27

27 + 17.5 = 44.5

2.) 44.5cm²

3.) 3.14 x 3² = 28.27

3.14 x 6² = 113.1

28.27 + 113.1 = 141.37

3.) 141.37cm²

4.) 3.14 x 4² ÷ 2 = 25.135

4 x 2 = 8

8 x 9 ÷ 2 = 36

8 + 36 = 44

4.) 44cm²

if any of these are wrong, let me know

hope this helps:)

Answer:

Number 1: 3 hours.

Number 2: $2434.04

Step-by-step explanation:

3/4 + 3/4 = 1 1/2 (after some simplifying)

1 1/2 + 1 1/2=3. She practiced 3 hours.

Number 2 will be harder to explain. We have 3 sides. That means 90 1/4 x 3. That is 270 3/4. 270 x 8.99 (8.99 per foot) gets us 2427.3, 3/4 x 8.99 (rounded to nearest hundreths) gets us 6.74. We add that together, and we get $2434.04.

I am pretty sure about 1, although not so sure about 2. Hope that helps you.

The first answer would work out to be 3 hours

While walking to the gym, Marie decides to play a game using a her lucky fair
six-sided die (which she carries with her all the time). Tossing an even number would
indicate walking forward that many steps and, likewise, tossing an odd number would
mean walking backwards that many steps (i.e. if she tosses a 3, she walks backward 3
steps). If the probability that after 2 rolls of the die, she is further away from the gym
that she was at the beginning of the game, can be represented as m/n
for m and n being relatively prime positive integers, find m^2 + n^2 ?

Sue saved $360. She spent 75% of her savings. How much does she have left

Answers

Answer:

Step-by-step explanation:

Expense = 75%

Percentage of amount left = (100 -75)% = 25%

25% of 360 = 0.25* 360 = 90

Remaining amount left with Sue = $ 90

She would only have 25% remaining so 25% times 360 is $90

The mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.

What is mean absolute deviation?

It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.

We have data as shown in the picture in the form of frequency graph.

The mean = 11/4 = 2.75

The difference between each value and mean is shown in the attached table.

MAD = 5/4 = 1.25

The nearest value is 1.1.

Thus, the mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.

a skydiver jumps out from the plane at 10,000 feet above the ground. the skydiver decends at a rate of 175 feet per seconds. how high in the air is the skydiver when he opens his parachute after 25 seconds?

Answers

Answer:

5625 feet

I hope it's helps you

Answer:

5625 feets

Step-by-step explanation:

Rate(feet/seconds) = height(feets)/time(seconds)

175 = x/25

x = 4375

After the skydiver opens his parachute the height reduces

Initial height – reduced height

10000 – 4375

= 5625 feets
