Find the area of a sector of a circle with radius 7 cm and and central angle 240°.

Answers

Answer 1
The formula for finding area of a sector is angle/360 * area. Now plug in. Area of whole circle is 49pi. Central angle is 240. 240/360 = 2/3. 2/3*49pi = 98pi/3

A baker has three different recipes. Recipe A uses 3 cups of flour to make 12 rolls. Recipe B uses 5 cups of flour to make 24 rolls. Recipe C uses 11 cups of flour to make 48 rolls. Which recipe uses the most cups of flour per roll?

a) Recipe A
b) Recipe B
c) Recipe C
d) The ratios are all proportional

Answers

Answer:

Recipe A

Step-by-step explanation:

Hope this helped!!!

Answer:

[tex]{\huge\red{\fbox{{࿐αɴѕωєя࿐}}}}[/tex]

Recipe A:

Cups of flour used = 3

Rolls made = 12

Cups of flour per roll

[tex] = \frac{3}{12} \\ = \frac{1}{4} \\ = 0.25[/tex]

Recipe B:

Cups of flour used = 5

Rolls made = 24

Cups of flour per roll

[tex] \frac{5}{24} \\ = 0.20[/tex]

Recipe C:

Cups of flour used = 11

Rolls made = 48

Cups of flour per roll

[tex] \frac{11}{48} \\ = 0.22[/tex]

Now compare Recipe A, B & C.

[tex]0.25 > 0.22 > 0.20[/tex]

Recipe A > Recipe C > Recipe B.

✏ So, Recipe A used the most cups of flour per roll (option a).

Step-by-step explanation:

a)

Two of the three interior angles are known. Both are equal to 55°. This can be seen by looking closely at the picture. To find the third angle subtract the other two from 360°

[tex]360\textdegree-55\textdegree-55\textdegree=x[/tex]

b)

Juan compro un plasma en cuotas que costó $8000 si le faltan pagar 3 cuotas y ya pagó $6500 ¿cual es el valor de cada cuotas fijas?

Answers

Answer:

El valor de cada cuota fija es de $500.

Step-by-step explanation:

Para encontrar el valor de cada cuota fija, puedes calcular la diferencia entre lo que Juan ha pagado y el valor que costó el plasma para saber cuál es el monto que aún debe. Después, debes dividir la cantidad que aún debe pagar entre tres que es el número de cuota pendientes para encontrar el valor de cada cuota teniendo en cuenta que son fijas:

8000-6500=1500

1500/3=500

De acuerdo a esto, la respuesta es que el valor de cada cuota fija es de $500.

Answers

Answer:

x = 29.5

y = 48.16

z = 34.05

Step-by-step explanation:

Sorry if the explanation is messy

answer

x=29.44

y=48.08

z=68

Step-by-step explanation:

opp/adj = tan(30)

17/x = tan(30)

x = 29.44

hyp^2 = x^2+y^2

hyp^2 = (29.44)^2 + (17)^2

hyp^2 = 867 + 289

hyp = 34

opp/hyp = Sin(45)

34/y = Sin(45)

y = 48.08

adj/hyp = Cos(45)

z/(48.08) = Cos(45)

z = 68

As shown, several colored paper squares are placed in a bowl. One paper square is randomly selected. Is this a uniform or non-uniform probability model? Justify your reasoning. A) It is a uniform probability model because each color has an equal chance of being selected. B) It is a non-uniform probability model because each color has an equal chance of being selected. C) It is a uniform probability model because each color does not have an equal chance of being selected. D) It is a non-uniform probability model because each color does not have an equal chance of being selected.

Answers

Answer:

B it is a non-uniform probability model because each color has an equal chance of being selected

Step-by-step explanation:

Developing a uniform probability model by assigning equal probability to all. If we select one student at random from the ten, is that a uniform then student name or grade level or color of their shirt or shoe size or different that the probability model uniform is different so that means the model is a non-uniform

En una tienda de ropa vas a comprarte una pantalones que están de 150 a 90 euros y una camiseta de 40 a 24 ¿ tienen el mismo porcentaje de rebaja ?

Answers

Respuesta:

Sí, tienen el mismo descuento del 40%

Explicación paso a paso:

Dado :

PANTALÓN :

Precio inicial = 150

Precio con descuento = 90

Porcentaje de descuento en el precio:

(150 - 90) / 150 * 100%

60/150 * 100%

0,4 * 100

= 40%

CAMISA:

Precio inicial = 40

Precio con descuento = 24

Porcentaje de descuento en el precio:

(40-24) / 150 * 100%

16/40 * 100%

0,4 * 100

= 40%

Answers

Answer:

The relation between the sides and angles of a right triangle is the basis for trigonometry.

Step-by-step explanation:

The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b ).

Answer:

The legs

Step-by-step explanation:

In a right triangle, sides a and b are called "the legs." These are the sides that create the right angle. Side c is called the hypotenuse and it is the longest side of a right triangle. Side c is opposite of the right angle.

Answers

Answer:

a) 58.24 square centimeters

b) 5cm

Step-by-step explanation:

a) Area of a parallelogram

The formula for the Area of a parallelogram = Base × Height

Height : 5.2cm

Base : 11.2cm

Area = 5.2 cm × 11.2cm

= 58.24 square centimeters

b) Volume of a cuboid

The formula for the Volume of a cuboid = Length × Width × Height

7cm = Width

3cm = Length

y = Height

Volume = 105cm³

We are to find y

Hence,

105cm³ = 7cm × 3cm × y

y = 105cm³/7cm × 3cm

y = 5cm

At a certain middle school, there are 200 5th graders, 220 6th graders, 180 7th graders, and 150 8th graders. The Dean of Students chooses a scholar at random to help run Community Circle. What is the probability that a 7th grader is chosen?

Answers

Answer:

6/25

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

probability that a 7th grader is chosen = total number of 7th graders / total number of students

total number of 7th graders = 180

total number of students = 200 + 220 + 180 + 150 = 750

180 / 750

Jacob sold 40 candy bars and made $65. He sold two types of
bars - chocolate for $2 each and peanut butter for $1 each.
How many of each type of candy bar did Jacob sell?

Answers

Answer:

Jacob sold 25 bars - chocolates and 15 peanut butter.

Step-by-step explanation:

Jacob sold 40 candy bars.

Let the bars - chocolate be x and peanut butter be y and made $65.

Now,

x + y = 40 ...(1)

2x + y = 65 ...(2)

Now, From equation (1) we get,

x + y = 40

x = 40 - y

Now, put the value of x = 40 - y in equation (2) we get,

2x + y = 65

2(40 - y) + y = 65

80 - 2y + y = 65

y = 80 - 65

y = 15

Now, put the value of y in equation (1)

x + y = 40

x + 15 = 40

x = 40 - 15

x = 25

The bars - chocolate = x = 25 and

peanut butter = y = 15

Thus, Jacob sold 25 bars - chocolates and 15 peanut butter.

It is desired to estimate the average weight of a new born baby. The birth records of arandom sample of 60 babies' weights showed a mean of 7.0 lbs and standard deviation of 1.5 lbs.Construct a 95% confidence interval forμ.

Answers

Answer:

95% confidence interval for the mean

(6.61251, 7.38749)

Step-by-step explanation:

Step:-1

Given that a random sample 'n' = 60

Given that mean of the sample x⁻ = 7.0

Given that the standard deviation of the sample (S) = 1.5

Level of significance = 0.05

Degrees of freedom = n-1 = 60-1 = 59

t₍₀.₀₅ , ₙ₋₁₎ = 2.0010

Step(ii):-

95% confidence interval for the mean is determined by

[tex](x^{-} - t_{0.05,n-1} \frac{S.D}{\sqrt{n} } , x^{-} + t_{0.05 , n-1} \frac{S.D}{\sqrt{n} } )[/tex]

[tex]( 7.0 - 2.0010 \frac{1.5}{\sqrt{60} } , 7.0 + 2.0010 \frac{1.5}{\sqrt{60} } )[/tex]

(7.0 - 0.38749 , 7.0 + 0.38749)

Final answer:-

95% confidence interval for the mean

Step-by-step explanation:

You can simply apply BODMAS(Bracket of Division Multiplication Addition Subtraction)

Step-by-step explanation:

First you do the things inside the parenthesis which is 62 + 1 = 63

Which gives you this  -----> 4[ 3 x 63]-36

Then do the brackets (brackets are these btw "[ ]" )

After doing the brackets you should bet this 4 x 189 - 36

Then you do the multiplication -----> 756 - 36

756 - 36 = 720
