Can someone help ASAP please?

Answer:

60

Step-by-step explanation:

Ok. first you want to determine the size of each side. 5 x 9 = 45 gets you the rectangle. You already have the tricky part, which is getting the width of the triangle. Now what you do is add  2.5 + 2.5 + 5 for the length, then you can do simple math and say 2.5 + 2.5 + 5 = 10

10 x 3 = length x width = 30, but since it's a triangle divide it by 2 and you'd get 15.

Now all you do is add them together and you get 60

The mean is equal for Group A and Group B.

Two groups of students were asked how far they lived from their school.

The table shows the distances in miles:

Group A (distance in miles) 1 1.5 3.03 3.2 2.8 1.5 1.8 2.5 2.2

Group B (distance in miles) 2 2.5 3.23 1.3 1.8 2.4 3 1.5 1.8

The mean of any data set or observation is equal to the sum of all the observations and divided by the number of observations.

The formula used to calculate the mean is;

[tex]\rm Mean = \dfrac{Sum \ of \ all \ observation}{Number \ of \ obrservation}[/tex]

The mean of group A is;

[tex]\rm Mean = \dfrac{Sum \ of \ all \ observation}{Number \ of \ obrservation}\\\\\rm GroupA \ mean = \dfrac{1 + 1.5 + 3.03 + 3.2 + 2.8 + 1.5 + 1.8 + 2.5 + 2.2}{9 }\\\\\rm Group A \ mean=\dfrac{ 19.53}{9}\\\\ Group A \ mean = 2.17[/tex]

The mean of group B is;

[tex]\rm Mean = \dfrac{Sum \ of \ all \ observation}{Number \ of \ obrservation}\\\\\rm Group B \ mean = \dfrac{2 + 2.5 + 3.23 + 1.3 + 1.8 + 2.4 + 3 + 1.5 + 1.8}{9} \\\\Group B \ mean = \dfrac{19.53}{9}\\\\ Group B \ mean = 2.17[/tex]

Hence, the mean is equal for Group A and Group B.

Answer:

  c = 29, A = 48°, B = 54°

Step-by-step explanation:

The unknown side is c. Using the last Law of Cosines formula, we find it to be ...

  c² = a² +b² -2ab·cos(C)

  c² = 22² +24² -2(22)(24)cos(78°) ≈ 840.445

  c ≈ √840.445 ≈ 29 . . . . . rounded to integer

__

The angle at B can be found using the Law of Sines. We want the angle in the numerator, so we can write the equation as ...

  sin(B)/b = sin(C)/c

  B = arcsin(b/c·sin(C)) ≈ arcsin(24/28.9904×sin(78°))

  B ≈ 54°

The remaining angle can be found using the sum of angles of a triangle:

  A +B +C = 180°

  A = 180° -B -C = 180° -54° -78° = 48°

The solution to the triangle is ...

  c = 29, A = 48°, B = 54°

Answer:

x = 12

Step-by-step explanation:

Step 1: Add 9 to both sides.

Step 2: Divide both sides by 7.

Step 3: Check if solution is correct.

Therefore, x = 12.

Answer:

x = 12

Step-by-step explanation:

This is a multi-step equation.

The first thing we can do is add 9 to both sides, eliminating the -9 from the left side of the equation. Now we have 7x = 84.

You can divide 84 over 7x to get a total of x =12.

Answer: The answer is 78

Step-by-step explanation: I had just taken the quiz

The measure of angle 2 is 78°. Therefore, option C is the correct answer.

Given that, lines m and n are parallel and intersect transversal t.

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

From the figure given m∠8=78°

m∠8=m∠6 (Vertically opposite angles are congruent)

m∠6=78°

m∠6=m∠2 (Corresponding angles on parallel line are equal)

So, m∠2=78°

The measure of angle 2 is 78°. Therefore, option C is the correct answer.

Step-by-step explanation:

The distance the outfielder must throw the ball to return it to the pitcher is 125 feet.

Given

On a softball field, the home plate is 43 feet from the pitcher’s mound.

A ball is hit at an angle of 27° east of the pitcher’s mound.

The ball travels 162 feet before it is caught by an outfielder.

Distance of the home plate from the pitcher's mound = 43 feet

The angle at which the ball is hit = 27° east of the pitcher's mound

The distance the ball travels before it is caught = 162 feet

The sides, b and c, and the included angle, A, of the triangle drawn are respectively;

b = 43 feet

c = 162 feet

A = 27°

The length of the third side, of the triangle, is the distance from the outfielder to the pitcher.

According to the law of cosines, we have;

a² = b² + c² - 2·b·c·cos(A)

a² = 43² + 162² - 2 × 43 × 162 × cos(27°) ≈ 15679.497105

Approximating to the nearest foot, we get;

a = 125 feet

Hence, the distance the outfielder must throw the ball to return it to the pitcher is 125 feet.

Answer:

The number of chicken and cows should be 19 and 11.

Step-by-step explanation:

The number of chicken and cows should be 19 and 11.

Given that,

The farm has 30 chickens and cows, and there are 82 chicken and cow legs all together.

Let x represent the number of chickens in the farm.

Let y represent the number of cows in the farm.

Based on the above information, the calculation is as follows:

x + y = 30

Since a chicken has 2 legs and a cow has 4 legs.

So,  

2x + 4y = 82 - - - - - - - - - - - - 1

Now  

Substituting x = 30 - y into equation 1, it becomes

2(30 - y) + 4y = 82

60 - 2y + 4y = 82

- 2y + 4y = 82 - 60

2y = 22

y = 11

Now

x = 30 - 11

= 19

Answer:

40% Use the ratio method

Step-by-step explanation:

Since

10 : 25 = X : 100

Then we know

10/25 = X/100

Multiplying both sides by 100 cancels on the right

100 × (10/25) = (X/100) × 100

100 × (10/25) = X

Then solving for X

X = 100 × (10/25)

X = 40

Therefore

10 : 25 = 40 : 100
