for # 1 the answer is B

for the second one i dont know

for the last one the answer is D

Step-by-step explanation:

Given:

A figure of a kite.

To find:

The area of the given kite.

Solution:

The area of a kite is the half of the product of its diagonals.

[tex]A=\dfrac{d_1d_2}{2}[/tex]             ...(i)

Where, [tex]d_1,d_2[/tex] are two diagonals of the kite.

From the given figure it is clear that the length of one diagonal is the sum of 12 and 8.

[tex]d_1=12+8[/tex]

[tex]d_1=20[/tex]

Let the second diagonal be 2x. The first diagonals bisect the second diagonal. So, the length of one parts of the diagonal is x.

Diagonals of a kite are perpendicular to each other. Using Pythagoras theorem, we get

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

[tex]13^2=x^2+12^2[/tex]

[tex]169-144=x^2[/tex]

[tex]25=x^2[/tex]

[tex]5=x[/tex]

The length of second diagonal is:

[tex]d_2=2x[/tex]

[tex]d_2=2(5)[/tex]

[tex]d_2=10[/tex]

Substituting [tex]d_1=20,d_2=10[/tex] in (i), we get

[tex]A=\dfrac{20\times 10}{2}[/tex]

[tex]A=\dfrac{200}{2}[/tex]

[tex]A=100[/tex]

Therefore, the area of the kite is 100 square units.

Answer:

Option A. 47°

Step-by-step explanation:

In the given triangle as per sine rule

sin F/DE = sin D/54

sin 71/70 = sin D/54

sin D = (54×sin 71)/70 = 54×0.9455/70 = 51.06/70 = 0.729

Therefore Option A. angle D = 47° is the answer.

Answer:

The length of the arc is approximately 2.0944

Step-by-step explanation:

The given parameters are;

The equation of the circle = x² + y² = 1

The radius of the circle, r = 1

The equation of the line, y = 1/2

Therefore, we point where the line intersects with the circle are given as the points 'y = 1/2' as follows;

When y = 1/2, the equation of the circle becomes;

x² + (1/2)² = 1

x² = 1 - (1/2)² = 3/4

x = ±√3/2

The angle subtended by the arc, θ = 2 × arctan((√3/2)/(1/2)) = 120°

The circumference of the circle, C = 2·π·r

∴ C = 2 × π × 1 = 2·π

The length of the arc, l = (θ/360) × C

∴ l = (120/360) × 2·π = (2/3)·π

The length of the arc, l = (2/3)·π ≈ 2.0944

The length of the arc is approximately 2.09

From the question, we have the following parameters

The equation of the circle = x² + y² = 1

The radius of the circle, r = 1

The equation of the line, y = 1/2

The line intersects with the circle are given as the points 'y = 1/2' as follows;

When y = 1/2, the equation of the circle becomes;

x² + (1/2)² = 1

x² = 1 - (1/2)² = 3/4

x = ±√3/2

Determine the subtended angle

The angle subtended by the arc is expressed as:

θ = 2 × arctan((√3/2)/(1/2))

θ = 120°

The circumference of the circle, C = 2·π·r

C = 2 × π × 1 = 2·π

The length of the arc, l = (θ/360) × C

l = (120/360) × 2·π = (2/3)·π

The length of the arc, l = (2/3)·π ≈ 2.09

The length of the arc is approximately 2.09

Answer:

We know that for every (3/4) cups of sugar, she uses (1/2) cups of flour.

Now let's find how much flour she needs to use for each case:

If she uses (1/8) cups of sugar, how much flour she uses?

First, we need to count how many times we have (3/4) cups of sugar in (1/8) cups of sugar, which is the quotient:

(1/8)/(3/4) = 4/(3*8) = 4/24 = 1/6

This means that we need to use (1/6) times (1/2) cups of flour.

this is:

(1/6)*(1/2) cups of flour = (1/12) cups of flour.

If she uses (4/3) cups of sugar, we need to count how many times we have (3/4) cups of flour in that amount, this is:

(4/3)/(3/4) = (4*4)/(3*3) = 16/9

Then we need to se (16/9) times (1/2) cups of flour, this is:

(16/9)*(1/2) cups of flour = (16/18) cups of flour = (8/9) cups of flour

If she uses (1/2) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:

(1/2)/(3/4) = 4/(2*3) = 4/6

Then she needs to use (4/6) times (1/2) cups of flour

this is:

(4/6)*(1/2) cups of flour = 4/(6*2) cups of flour = (1/3) cups of flour.

If she uses (1/4) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:

(1/4)/(3/4) = 4/(4*3) = 4/12

Then she needs to use (4/12) times (1/2) cups of flour

this is:

(4/12)*(1/2) cups of flour = 4/(12*2) cups of flour = (1/6) cups of flour.

If she uses (1/5) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:

(1/5)/(3/4) = 4/(5*3) = 4/15

Then she needs to use (4/15) times (1/2) cups of flour

this is:

(4/15)*(1/2) cups of flour = 4/(15*2) cups of flour = (2/15) cups of flour.

Answer:

6 centimeters

Step-by-step explanation:

There are 6 sides, so each side would have an area of 216/6 = 36.

Then, since each side is a square you know that the length of one side would be [tex]\sqrt{36} = 6[/tex]

x + 83° = 180°

x = 180° - 83°

Answer: [tex]\frac{5}{4}\ ft[/tex]

Step-by-step explanation:

Given

Maria kite tail is [tex]3\ \frac{1}{2}\ ft[/tex] long

Max's kite tail is [tex]2\ \frac{1}{4}\ ft[/tex] long

Converting it to a fraction

Maria kite tail

[tex]\Rightarrow \dfrac{3\times2+1}{2}=\dfrac{7}{2}\ ft[/tex]

Max's kite tail

[tex]\Rightarrow \dfrac{2\times4+1}{4}=\dfrac{9}{4}\ ft[/tex]

Difference between lengths

[tex]\Rightarrow \dfrac{7}{2}-\dfrac{9}{4}\\\Rightarrow \dfrac{14-9}{4}=\dfrac{5}{4}\ ft[/tex]

Max's tail is [tex]\frac{5}{4}\ ft[/tex] short than Maria kite tail

Answer:

15.D

16.A

Step-by-step explanation:

Hello There!

For 15

We can find the slope given two points by using the slope formula

[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

so given the two points (2,-3) and (-2,5)

we plug in the y values and x values into the formula

[tex]slope=\frac{5-(-3)}{-2-2} \\5-(-3)=8\\-2-2=-4\\slope=\frac{8}{-4}[/tex]

Finally we want to simplify

8/-4=-2

so we can conclude that the slope of a line that passes through the points (2,-3) and (-2,5) is -2 (D)

For 16

The y intercept is at (0,0) meaning that at 0 hours there was no water in the pool

So we can conclude that the pool was originally empty

Answer:

below sea level;

-100 feets

Step-by-step explanation:

Given that:

Dallas, Texas elevation = 200 feets

Jacksonville = 300 feets less than elevation of Dallas

Hence, elevation of Jacksonville :

Dallas elevation - 300 feets

200 feets - 300 feets = - 100 feets

Hence Elevation of Jacksonville city is - 100 feets

-100 feets, means elevation of Jacksonville city is below sea level (elevation points less than 0, are below sea level).

answer: 8

Explanation:

Use the formula for the area of a circle:

A = π r 2

Here, the area is  16 π

16 π = π r 2  

Divide both sides by  

16 = r 2

Take the square root of both sides:

√ 16 = √ r 2

4 = r

Since the radius of the circle is  

4

, the diameter is twice that:

d = 4 × 2 = 8

Answer:48-8=40 the temperature range is 8. , I think.

The interquartile range (IQR) of the data set is 24 degrees Celsius.

The interquartile range (IQR) is a measure of variability or spread in a dataset. It is the difference between the third quartile (Q'') and the first quartile (Q) of the dataset.

To calculate the interquartile range (IQR) of this data set, we first need to find the first quartile (Q) and the third quartile (Q'').

Arrange the data in order from smallest to largest:

08, 09, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48

Find the median (Q') of the entire data set:

Median (Q') = (24 + 28)/2 = 26

Find Q by taking the median of the lower half of the data:

Lower half: 08, 09, 12, 16, 20, 24

Q = (12 + 16)/2 = 14

Find Q'' by taking the median of the upper half of the data:

Upper half: 28, 32, 36, 40, 44, 48

Q'' = (36 + 40)/2 = 38

Calculate the IQR by subtracting Q from Q'':

IQR = Q'' - Q = 38 - 14 = 24

Therefore, the interquartile range (IQR) of this data set is 24 degrees Celsius.

Answer:

1/20

Step-by-step explanation:

Karina ate 1/2 of the muffins. Ulysses ate 1/4 of the muffins. Zawanna ate 1/5 of the muffins. Juan ate the rest of the muffins. What fraction of the muffins did Juan eat?

Let the total number of muffins = 1

Hence:

The fraction of muffins Juan ate =

1 - (1/2 + 1/4 + 1/5)

Lowest common denominator is 20

1 - ( 10 + 5 + 4/20)

1 - 19/20

= 1/20

The Fraction of muffins Juan ate is 1/20
