How Do I Solve This?

Answers

Answer 1

Answer:

A,

Step-by-step explanation:

Opposites sides are equal in a rectangle.

Answer 2

Answer:

The answer is: "It has to be a rectangle.  I measured the diagonals to be sure they were the same length."

Step-by-step explanation:

The other properties are true of a rectangle as well, but they could also be other shapes.

"It has to be a rectangle.  The opposite sides are the same length."

This could also be describing a rhombus or square.

"It has to be a rectangle because it is not a square."

This could also be a rhombus, trapezoid, or even kite.

"It has to be a rectangle.  I made sure that the two 8-foot boards are parallel and that the two 6-foot boards are parallel."

This can describe any parallelogram.  Just because the sides are congruent and parallel does not mean that there are four 90degree angles formed.

"It has to be a rectangle.  I measured the diagonals to be sure they were the same length."

This is a property of rectangle diagonals.  They will always be congruent.

A water spout is filling a large container with water. After 5 hours the container held 24L of water. After 8 hours the container held 30L of water. At this rate, how much water was in the container at 2 hours?

Answers

Answer:

Step-by-step explanation:

This is a direct proportionality. If a water spout is filling a large container with water, hence the time taken to fill the container is directly proportional to the volume v of water. MAthematically;

t = kV

If after 5 hours the container held 24L of water, then;

5 = 24k

k = 5/24

Also if after 8 hours the container held 30L of water

8 = 30k

k = 8/30

To get the rate of the container at 2 hrs

5[tex]\frac{7}{8}[/tex]

Step-by-step explanation:

You subtract all those distances from 22 to calculate the remaining distance.

22-4[tex]\frac{3}{4}[/tex]= 17[tex]\frac{1}{4}[/tex]

17[tex]\frac{1}{4}[/tex]-5[tex]\frac{1}{8}[/tex]=12[tex]\frac{1}{8}[/tex]

12[tex]\frac{1}{8}[/tex]-0=12[tex]\frac{1}{8}[/tex]

12[tex]\frac{1}{8}[/tex]-6[tex]\frac{1}{4}[/tex]=5[tex]\frac{7}{8}[/tex]

So the answer is 5[tex]\frac{7}{8}[/tex]

From a distance of 1217 feet from a spotlight,the angle of elevation to a cloud base is 43 degrees. Find the height of the cloud base to the cloud base to the nearest foot

Answers

Answer:

1134.9 ft

Step-by-step explanation:

CHECK THE ATTACHMENT FOR THE FIQURE

From, trigonometry,

Tan(X) = opposite/ adjacent

Distance from the spotlight = 1217 ft, which is the adjacent sides

Let the height of the cloud= X

, Which is the opposite sides

Then substitute, we have

Tan(43°)= X/1217

(0.9325)= X/1217

X= 0.9325×1217

= 1134.9 ft

Hence, the height of the cloud base to the cloud base to the nearest foot is 1134.9 ft

Aubree recorded the grade-level and instrument of everyone in the middle school School of Rock below.
Seventh Grade Students
Instrument # of Students
Guitar 9
Bass 12
Drums 4
Keyboard 7
Eighth Grade Students
Instrument # of Students
Guitar 12
Bass 14
Drums 5
Keyboard 8

Based on these results, express the probability that a seventh grader chosen at random will play an instrument other than drums as a percent to the nearest whole number.

Answers

Answer:

88%

Step-by-step explanation:

probability of 7th grader playing other instruments apart from drum = total number of students not playing drum / population of the 7th grade class

total number of students not playing drum = 9 + 12 + 7 = 28

population of the 7th grade class = 28 + 4 = 32

28/32 = 0.875

to express in percentage multiply by 1000 = 87.5%

To round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.
