Anna has to straighten her arm from 90° to 118°. She can straighten it
by about 12° every 3 days. How many days will it take to get to 118°?​

Answer:

32

Step-by-step explanation:

put the numbers in order from less to greatest

3,13,14,16,27,37,42,64,95,97

the middle numbers are 27 and 37

27+37 is 64

64 divided by 2 is 32

First put the numbers in order from least to greatest

3, 13, 14, 16, 27, 37, 42, 64, 95, 97

Median means middle so find the middle number by deleting the least and greatest number in each "layer"

3, 13, 14, 16, 27, 37, 42, 64, 95, 97

   13, 14, 16, 27, 37, 42, 64, 95

         14, 16, 27, 37, 42, 64

               16, 27, 37, 42

                     27, 37

You have two numbers left. To find the middle take the mean of these two numbers, by adding them together then dividing the sum by two

27 + 37 = 64

64 / 2 = 32

32 is the median!!!

Answer:

128

Step-by-step explanation:

To create 128 different hamburgers with multiple combinations of condiments, you would need 7 different condiments. This is due to the fact that each condiment presents 2 possibilities, on the burger or not, and 2 to the power of 7 equals 128.

In this scenario, each condiment represents an option that can be either included or excluded. This means that, for each condiment, there are 2 possibilities (it's either on the burger, or it's not). The question implies that the number of possible combinations equals 128, which is 2 to the power of 7.

So, to create 128 different hamburgers, the restaurant must offer 7 different condiments. This is because 2 (possibilities for each condiment) to the power of 7 (condiments) equals 128.

Answer:

0.589

Step-by-step explanation:

THis is a conditional probability question. Let's look at the formula first:

P (A | B) = P(A∩B)/P(B)

" | " means "given that".

So, it means, the "Probabilty A given that B is equal to Probability A intersection B divided by probability of B."

So we want to know P (Female | Undergraduate ). This in formula is:

P (Female | Undergraduate) = P (Female ∩ Undergraduate)/P(Undergraduate)

Now,

P (Female ∩ Undergraduate) means what is common in both female and undergraduate? There are 43% female that are undergrads. Hence,

P (Female ∩ Undergraduate) = 0.43

Also,

P (Undergraduate) is how many undergrads are there? There are 73% undergrads, so that is P (undergraduate) = 0.73

plugging into the formula we get:

P (Female | Undergraduate) = P (Female ∩ Undergraduate)/P(Undergraduate)

=0.43/0.73 = 0.589

this is the answer.

A = 18 m²

true

any given point in a circle is equal distance from the center

Answer: TRUE.

Step-by-step explanation:

It knows that the distance "d" between any two points is equal to [tex]\sqrt{(x-x_0)^2-(y-y_0)^2}[/tex].

In a circle the distance between a point that belongs to the circumference and the center ([tex]x_0,y_0[/tex]) is always the same. Then:

[tex]\sqrt{(x-x_0)^2-(y-y_0)^2}[/tex] is always equal to a constant called "r".

This is:

[tex]\sqrt{(x-x_0)^2-(y-y_0)^2}=r[/tex]

Square both sides of the equality:

[tex](\sqrt{(x-x_0)^2-(y-y_0)^2})^2=r^2[/tex]

[tex](x-x_0)^2-(y-y_0)^2=r^2[/tex]

Note that we obtain the General equation of a circle.

This prove that if the distance between a given point in the plane and a collection of points is equal, then the equation of a circle is obtained.

Therefore, the statement "A circle is the collection of points in a plane that are the same distance from a given point in the plane." is true.

1) [tex]b=101\degree[/tex]

2) [tex]m=50\degree[/tex]

3) [tex]h=79\degree[/tex]

4) [tex]g=101\degree[/tex]

5) [tex]i=51\degree[/tex]

6) [tex]j=130\degree[/tex]

Explanation

From the diagram,

[tex]b=101\degree[/tex], corresponding angles are equal.

From the diagram, m=k, corresponding angles are equal.

But k+130=180, angles on a straight line sum up to 180 degrees.

This implies that k=180-130=50

[tex]\therefore m=50\degree[/tex]

From the diagram ; [tex]h+101=180\degree[/tex],angles on a straight line sum up to 180 degrees.

[tex]\implies h=180-101\degree[/tex]

[tex]\implies h=79\degree[/tex]

From the diagram, [tex]g=101\degree[/tex] vertically opposite angles are equal.

From the triangular portion;

i+h+m=180. sum of interior angles of a triangle.

This implies that:

i+79+50=180

i+129=180

i=180-129

[tex]i=51\degree[/tex]

Finally

[tex]j=130\degree[/tex], vertically opposite angles are equal.

Answer:

Part 1) ∠b=101°

Part 2) ∠m=50°

Part 3) ∠h=79°

Part 4) ∠g=101°

Part 5) ∠i=51°

Part 6) ∠j=130°

Step-by-step explanation:

Part 1) ∠b

we know that

∠b=101° ------> by corresponding angles

Part 2) ∠m

we know that

∠m=∠k ------> by corresponding angles

and

∠k+130°=180° -----> by supplementary angles

∠k=180°-130°=50°

therefore

∠m=50°

Part 3) ∠h

we know that

∠h+101°=180° -----> by supplementary angles

∠h=180°-101°=79°

Part 4) ∠g

we know that

∠g=101° -----> by vertical angles

Part 5) ∠i

we know that

The sum of internal angles of a triangle must be equal to 180 degrees

so

∠h+∠m+∠i=180°

substitute the values and solve for ∠i

79°+50°+∠i=180°

∠i=180°-129°=51°

Part 6) ∠j

we know that

∠j=130° -----> by vertical angles

As we know distance equals speed multiplied by time

118*2.25=265.5

Therefore the car can travel 265.5km in 2 hours 15 minutes with the speed of 118km/h

The van can travel approximately 265.5 kilometers in 2 hours and 15 minutes.

To find out how far the van can travel in 2 hours and 15 minutes, we need to use the formula:

Distance = Speed × Time

Given:

- Speed of the van = 118 km/h

- Time = 2 hours 15 minutes

First, let's convert the time to hours:

2 hours 15 minutes = 2 + 15/60 hours

= 2.25 hours

Now, we can use the formula to calculate the distance:

Distance = 118 km/h × 2.25 hours

Distance ≈ 265.5 km

Therefore, the van can travel approximately 265.5 kilometers in 2 hours 15 minutes.

a)zw  = 44.295 cos(1.924) +isin(1.924))

b) z/w= 4.921 cos(-0.936) + isin(-0.936)

Step-by-step explanation:

Given:

z=13+7i

w=3(cos(1.43)+isin(1.43)  

a. convert zw using De Moivre's theorem  

First coverting z into  polar form:

13^2 + 7^2  = 14.765

[tex]\sqrt{14.765}[/tex] =r

θ= arctan (7/13)

 = 0.49394                            (28.301 in degrees)

z= 14.765(cos(0.49394)+isin(0.49394)  )

Now finding zw

zw= 14.765(cos(.494)+isin(.494))×3(cos(1.43)+isin(1.43))

Using De Moivre's theorem, the modulus will be multiplied

14.765 x 3=44.295

whereas the angles will be added

.494+1.43=1.924

Thus:

zw  = 44.295 cos(1.924) +isin(1.924))

b)

finding z/w

z/w= 14.765(cos(.494)+isin(.494)) / 3(cos(1.43)+isin(1.43))

Using De Moivre's theorem, the modulus will be divided

14.765 / 3 = 4.921

whereas the angles will be subtracted:

.494-1.43=-0.936

Thus:

z/w= 4.921 cos(-0.936) + isin(-0.936) !

The lateral area of the cone comes out to be 48984 m^2.

What is lateral area?

The formula of the lateral area of cone is given by, area = pi×r×L

The amount of territory occupied by the curved surface area of a cone is known as the lateral surface area.

The lateral surface area of a cone is also in the three-dimensional plane because it is a three-dimensional form. The shape of a cone is created by stacking and rotating several triangles around an axis. Since a cone has a flat base so it has curved surafce area as well as total surface area.  A cone's lateral area is measured in square units, such as cm2, m2, in2, and so on.

Given,

Height of cone : 50m

Diameter of cone: 240m

so,it's radius will be 120m

L = [tex]\sqrt{r^{2}+h^{2}}[/tex]

L = [tex]\sqrt{120^{2} +50^{2} }[/tex]

The width of the border around the stained glass window is approximately 1.15 feet, calculated by subtracting the stained glass area from the total area including the border.

To find the width of the border, we need to subtract the area of the stained glass window from the total area including the border.

Given:

- Length of stained glass window = 4 feet

- Width of stained glass window = 2 feet

- Area of stained glass window = [tex]\(4 \times 2 = 8\)[/tex] square feet

- Total area including the border = Area of stained glass window + Area of border = 8 + 7 = 15 square feet

Let's denote the width of the border as x feet.

The total length including the border is 4 + 2x feet, and the total width including the border is 2 + 2x feet.

The area of the total window with the border is the product of its length and width:

(4 + 2x)(2 + 2x) = 15

Expanding this equation:

8 + 4x + 4x + 4x^2 = 15

8 + 8x + 4x^2 = 15

4x^2 + 8x - 7 = 0

Now, let's solve this quadratic equation using the quadratic formula:

[tex]\[x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}\][/tex]

Where a = 4, b = 8, and c = -7.

[tex]\[x = \frac{{-8 \pm \sqrt{{8^2 - 4 \times 4 \times (-7)}}}}{{2 \times 4}}\][/tex]

[tex]\[x = \frac{{-8 \pm \sqrt{{64 + 112}}}}{8}\][/tex]

[tex]\[x = \frac{{-8 \pm \sqrt{{176}}}}{8}\][/tex]

[tex]\[x = \frac{{-8 \pm 4\sqrt{{11}}}}{8}\][/tex]

[tex]\[x = \frac{{-2 \pm \sqrt{{11}}}}{2}\][/tex]

Since the width cannot be negative, we take the positive root:

[tex]\[x = \frac{{-2 + \sqrt{{11}}}}{2} \approx 1.15 \text{ feet}\][/tex]

Therefore, the width of the border is approximately 1.15 feet.
