1. 18.8 units

2. 3 units

3. 9.4 units

Breaking the circle into more sectors

1. The circumference of circle is 18.8 units

2. The height of parallelogram is 3 unit.

3. The approximate length of the parallelogram if the base were completely straight is 9.4 unit

4. The estimation is easier by breaking down into sector.

5. Area of Circle is 28. 26 unit²

The circumference of the circle is 2πr where is the radius of the circle.

1. The circumference of circle

= 2πr

= 2 x 3.14 x 3

= 18.8 units

2. From Figure the height of parallelogram is 3 unit.

3. The approximate length of the parallelogram if the base were completely straight

= 18.8 / 2

= 9.4 unit

4. The estimation is easier by breaking down into sector.

5. Area of Circle

= πr²

= 3.14 x 9

= 28. 26 unit²

Answer:

297 ft squared

Step-by-step explanation:

find the area of the triangle, which is (bh)/2

(22*7)/2=77

find the area of the rectangle (bh)

22*10=220

add

77+220=297

First, -43-(-7) is the same as -43+7, which is equal to:-

-36

Is the answer positive or negative? The sign in front of 36 will tell us whether the number is positive or negative.

It is negative, because there's a minus sign next to it.

Answer:

? = 4

Step-by-step explanation:

2/13 + ?/13 = 6/13        (Given)

-2/13               -2/13      (Isolate the unknown through subtraction)

?/13 = 6/13 - 2/13        

?/13 = 4/13                    (Combine like terms)

? = 4

Because the demoninators are the same, the unknown value can be found using isolation techniques. To find the unknown, subtract 2/13 from both sides. This eliminates the 2/13 from the right side while obeying the rule that states that what is done to one side must to done to the other. This leaves the ?/13 by itself on the right and 4/13 on the left. Again, because the demoninators are identical, the unknown value must be 4.

Explanation:

90° is 90/360 = 1/4 of a full 360° rotation. Meaning that if the central angle of the pizza slice is 90°, then we have four equal slices.

One slice is 7 square inches, so all four slices combine to 7*4 = 28 square inches

The time taken by Nadia for her entire journey is 5 hours

Speed is the rate at which an object is moving, and it is defined as the distance traveled per unit of time. The formula for speed is:

           Speed = Distance/Time

Where distance is the distance traveled by an object and time is the time taken to travel that distance.

From the fomrula, we can write as

          Distance = Speed × Time

Here we have

Nadia walks at an average speed of (x + 2) km/h for (x – 3) hours and cycles at an average speed of (3x + 5) km/h for x hours.

As we know, Distance = Speed x Time  

Distance walked = (x + 2)(x - 3)

Distance cycled = (3x + 5)(x)

The total distance covered is given as 74 km,

=> (x + 2)(x - 3) + (3x + 5)(x) = 74

=> x² - 3x + 2x - 6 + 3x² + 5x = 74

=> 4x² + 4x - 80 = 0

Hence, the final equation is 4x² + 4x - 80 = 0

(ii) The quadratic equation, can be solved as follows

=> x² + x - 20 = 0  

=> x² + 5x - 4x - 20 = 0

=> x(x + 5) -4(x + 5) = 0

=> (x + 5) (x - 4) = 0

=> x = - 5 and x = 4

Here we cant take time as negative so take x = 4 hours

(iii) To find the time taken for her entire journey, we need to add up the time taken for walking and cycling:

Total time = (x - 3) + x

Total time = 2x - 3

Substituting the value of x  

Total time = 2(4) - 3 = 8 - 3 = 5

Therefore,

The time taken by Nadia for her entire journey is 5 hours

On cross multiplying,

Answer:

[tex]x=-2[/tex]

Step-by-step explanation:

Given equation:

[tex]\dfrac{3x+5}{2x+1}=\dfrac13[/tex]

Cross multiply:

[tex]\implies 3(3x+5)=1(2x+1)[/tex]

Expand brackets:

[tex]\implies 9x+15=2x+1[/tex]

Subtract [tex]2x[/tex] from both sides:

[tex]\implies 9x+15-2x=2x+1-2x[/tex]

[tex]\implies 7x+15=1[/tex]

Subtract 15 from both sides:

[tex]\implies 7x+15-15=1-15[/tex]

[tex]\implies 7x=-14[/tex]

Divide both sides by 7:

[tex]\implies \dfrac{7x}{7}=-\dfrac{14}{7}[/tex]

[tex]\implies x=-2[/tex]

Using the z-distribution, as we are working with a proportion, it is found that the margin of error for the 90% confidence interval is of 0.0524 = 5.24%.

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this problem, the critical value is given as z = 1.645, and since 26 out of 80 students said they would be willing to pay extra:

[tex]n = 80, \pi = \frac{26}{80} = 0.325[/tex]

Then, the margin of error is of:

[tex]M = 1.645\sqrt{\frac{0.325(0.675)}{80}} = 0.0524[/tex]

Each pound is divided into 16ths since 10 sixths are represented by the marker then the answer would be 10/16.

10 / 16 = 5 / 8


10 divided by 2 = 5

16 divided by 2 = 8

My answer is due to, it doesn't use the markers it goes by smaller numeral making me believe it uses the 16th instead of the 8th, also you can see it hits the tick mark for the bigger saying that is settled on making me think that is the answer.

To break it down why the others are not correct the [tex]\frac{4}{8}[/tex] is the mesurent saying it is half which it clearly is not half way. The other is [tex]\frac{7}{8}[/tex] butyou can see the marker is not nearly close enough for it to be almost to a pound. and the last option 1[tex]\frac{5}{8}[/tex] doesn't make sense it seems it would have to be more then a pound.

The experimental probability of a blue outcome is its likelihood

The experimental probability of blue is 0.4

The number of trials is given as:

Trials = 5

The outcomes of blue is given as:

Blue = 2

The experimental probability of obtaining a blue outcome is:

P(Blue) = Blue/Trials

This gives

P(Blue) = 2/5

Evaluate the quotient

P(Blue) = 0.4

2. D. no determination can be made

3. B. right

4. D. it cannot be determined

Step-by-step explanation:

1. If ∠KAT and ∠GIF are supplementary angles then one is acute and the other is obtuse

example : m∠KAT = 70° and m∠GIF = 110°

2.If ∠DEF and ∠IPN are congruent, they are no determination can be made

counter-example:

m∠DEF = 50° and m∠IPN = 50°

3.If the sides of a triangle measure 3, 4 and 5, then the triangle is right

because : 5² = 3² + 4²

4. If two sides of a triangle measure 4 and 14, and an angle measures 34º, then the triangle is it cannot be determined

The answer is B

seeing there are 3 way to put it

(a+b)(a-b)=a 2-b 2

(a+b)(a-b)=a^2-b^2
