Answer:

4XY-34

Step-by-step explanation:

1. x*y=xy

2.xy*4=4xy

3. 4xy-34

The mean is the average.

Add the number of contacts and divide by the number of people:

112 + 104 + 96 + 54 +98 +120 = 584

584 / 6 = 97.3

The mean = 97.3

Now add the standard deviation to the mean for the higher value and subtract the standard deviation from the mean for the lower value:

97.3 - 21 = 76.3

97.3 +21 = 118.3

The answer would be D.

Answer:

13 square units.

Step-by-step explanation:

We can find the area of the parallelogram using the formula:

[tex]Area=2\times \frac{1}{2}[|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|][/tex]

where [tex]A(x_1,y_1)[/tex], [tex]B(x_2,y_2)[/tex]. and [tex]C(x_3,y_3)[/tex] are the vertices of one of the triangles created by the diagonals.

[tex]Area=[|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|][/tex]

We use A(5, 3), B(8, 4), C(7, 8) to obtain:

[tex]Area=[|5(4-8)+8(8-3)+7(3-4)|][/tex]

[tex]Area=[|-20+40-7|][/tex]

[tex]Area=|13|=13[/tex]

The area of the parallelogram is 13 square units.

Answer:

24 ft up the wall

Step-by-step explanation:

We can use the Pythagorean theorem to solve, letting the 25 ft ladder be the hypotenuse

a^2 +b^2 = c^2

7^2 +b^2 = 25^2

49 + b^2 = 625

Subtract 49 from each side

49-49 +b^2 = 625-49

b^2 = 576

Take the square root of each side

sqrt(b^2) = sqrt(576)

b = 24

We only take the positive solution since length cannot be negative

The ladder will reach 24 ft up the wall

Answer:

∠1 = 72°

Step-by-step explanation:

Complementary angles sum to 90°, thus

∠1 + ∠2 = 90, substitute ∠1 = 4∠2 , thus

4∠2 + ∠2 = 90

5∠2 = 90 ( divide both sides by 5 )

∠2 = 18°

Hence ∠1 = 90 - 18 = 72°

ANSWER

6.4 hours

EXPLANATION

if it takes 10 hours to get 50%, then it will take less number of hours to get 32%

We use proportion to solve this question.

If less more divides.

The number of hours it will take to get 32% is

[tex] = \frac{32\% \times 10}{50\%} [/tex]

[tex] = 6.4[/tex]

Hence it will take 6.4 hours to get 32%

Explanation:

If you had one coin, then there are 2 outcomes because of the two sides heads or tails, which I'll shorten to H and T respectively.

With two coins, there are 2*2 = 4 outcomes (HH, HT, TH, or TT)

Having 3 coins there are 2*2*2 = 2^3 = 8 outcomes

4 coins and we have 2^4 = 2*2*2*2 = 16 outcomes

and so on

With 9 coins there are 2^9 = 512 different outcomes

Answer:

There are 2 outcomes per flip.

Therefore the answer is 2^9 which equals 512 outcomes.

Answer:

48in

Step-by-step explanation:

We know that the photograph is

Width photo = 5in

Lenght photo = 7in

The length and width of the frame are 2x inches larger than the width and frame of the photograph so:

Width frame = 5in x 2 = 10 in

Lenght frame = 7in x 2 = 14 in

The perimeter is the distance around a two-dimensional shape. Then, the perimeter of the frame is:

Perimeter = 10 in + 14 in + 10 in + 14 in = 48in

70%

A percentage is the same thing as a fraction with a denominator of 100. To make our current denominator change to 100, we must multiply it by 10. So, we must do the same thing to the numerator. 7 times 10 is 70, and 10 times 10 is 100. This means 7/10 equals 70/100, which is 70%.

On solving the given inequality, we get x > 11.81

Given is the following inequality -

81 - 11/5x ≤ 55

We have -

81 - 11/5x ≤ 55

(11/5)x ≥ 81 - 55

(11/5)x ≥ 26

(11/5)x ≥ 26

x ≥ = (26 x 5)/11

x > 11.81

Therefore, on solving the given inequality, we get x > 11.81

Answer:

w<240 pounds

Step-by-step explanation:

The inequality of weight is w≤250 pounds.

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), larger than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

A go-cart has a maximum weight limit of 240 pounds.

let the weight is represented by 'w'

We can use inequality sign here as ≤.

Now, in the given situation weight should be less than or equal to 250 pounds.

Hence, the equality is w≤250 pounds.

Answer:

9.36cm

Step-by-step explanation:

We can add up all the sides to find the perimeter.

[tex]x+2x+2x=5x[/tex]

So the perimeter, 46.8, is equivalent to 5x.

Solve.

[tex]5x=46.8 \\ \\ x=9.36[/tex]

So [tex]x[/tex] is 9.36.

Since the base is [tex]1x[/tex], the base is 9.36cm.

We can plug back in to check our answers.

[tex]2x=18.72\\9.36+18.72+18.72 = 46.8[/tex]

The answer is 9.36cm hope u do well :)

Answer: tasha needs at least 252 inches of ribbon

your exact answer should be 252 inches

Step-by-step explanation: multiply the width times height to find the area of a rectangle

Tasha requires 64 inches of ribbon to decorate the outer edge of her bulletin board. To determine this, we use the formula for the perimeter of a rectangle, 2*(length+breadth), substituting the dimensions of the board.

To calculate the amount of ribbon Tasha requires, you need to find the perimeter of the bulletin board. The perimeter of a rectangle (which is the shape of the bulletin board) is calculated by the formula 2*(length+breadth).

In this instance, the length is 18 in, and the width (or breadth) is 14 in. Substituting these values into the formula we get: 2*(18 in + 14 in) = 2*32 in = 64 inches. Thus, Tasha needs 64 inches of ribbon to decorate the entire outer edge of the bulletin board.

Answer:

x=5  y=-1

Step-by-step explanation:

7x-2y=37

[2(4x+y=19)]=

8x+2y=38

---------------------

15x/15=75/15

x=5

[4(5)+y=19]

y=-1

Final answer:

The solution to the given system of equations using elimination is x = 5 and y = -1. This was achieved by multiplying the second equation by 2 and then adding both equations to eliminate y.

Explanation:

We are given a system of linear equations and are asked to solve it using the method of elimination. We have the following equations:

1) 7x - 2y = 37

2) 4x + y = 19

To eliminate one of the variables, we can multiply the second equation by 2 to make the coefficient of y the same in both equations (but with opposite signs). After this step, our system looks like:

1) 7x - 2y = 37

2) 8x + 2y = 38

Now, adding the two equations will eliminate y, and we get:

7x + 8x = 37 + 38

15x = 75

x = 5

We can then substitute the value of x into one of the original equations to solve for y:

4x + y = 19

4(5) + y = 19

20 + y = 19

y = -1

So, the solution to the system is x = 5 and y = -1.

Step-by-step explanation:

Hope this helps!

For this case we must simplify the following expression:

[tex]\frac {2} {3} + \frac {5} {8}[/tex]

Then, we add the fractions making cross product:

[tex]\frac {2} {3} + \frac {5} {8} = \frac {8 * 2 + 3 * 5} {3 * 8} = \frac {16 + 15} {24} = \frac {31 } {24}[/tex]

Thus, the fraction can not be simplified.
