Find attached to this question, the diagram of the right angle triangle

Answer:

Leg a = 4

Step-by-step explanation:

A right angle triangle has 3 sides : side a, b and c

The formula to solved for a right angle triangle =

a² + b² = c²

In that above question,

a = unknown

b = 3

c = 5

Therefore,

a² + 3² = 5²

a² = 5² - 3²

a² = 25 - 9

a² = 16

a = √16

a = 4

Therefore, leg a = 4

Answer:

7/10

Step-by-step explanation:

Finding the totals of each column and row, we find:

There are 3+2+1 = 6 children in the baseball league.

There are 7+2+1 = 10 children in the softball league.

There are 3+7 = 10 children in the 7-9 division.

There are 2+2 = 4 children in the 10-12 division.

There are 1+1 = 2 children in the 13-15 division.

There are a total of 10+6 = 16 children.

We start with the information that the team is a member of the softball league.  There are 10 children in this league; this is the denominator of the probability.

There are 7 children in the 7-9 division that are in the softball league.  This gives us the probability 7/10.

Answer:

C. (4,0)

Step-by-step explanation:

Given a graph of the system of equations

3x+4y=12; and

2x-y=8.

We can see that both lines pass through (4,0). Therefore, (4,0) is a point of intersection of the two lines.

It is therefore a solution to the system of equations.

Step-by-step explanation:

Proportion of students using the app, p = 63/100 = 0.63

Proportion of students not using the app, q = 1 - 0.63 = 0.37

Sample size, n = 2

Probability that the two students are using the app.

[tex]P(X = r) = nCr p^{n} q^{n-r} \\P(X = 2) = 2C2 *0.63^{2} *0.37^{2-2}\\P(X = 2) = 2C2 *0.63^{2} *0.37^{0}\\P(X=2) = 0.63^{2} \\P(X=2) =0.3906[/tex]

The length of the diagonal of the rectangular prism will be √35 units. Then the correct option is B.

A closed solid with two parallel rectangular bases joined by a rectangle surface is known as a rectangular prism.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The dimension of the rectangular prism will be 3 units long, 5 units wide, and 1 unit high. Then the diagonal of the prism is given as,

D² = 3² + 5² + 1²

Simplify the equation, then we have

D² = 3² + 5² + 1²

D² = 9 + 25 + 1

D² = 35

D = √35 units

The length of the diagonal of the rectangular prism will be √35 units. Then the correct option is B.

Answer:(3x – 1) and (x + 4)

Step-by-step explanation:

Jenna needs to model the factors (3x – 1) and (x + 4) for the sides of the configuration. The correct answer would be an option (B).

Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original.

The model is given in the question, as follows:

3x² + 11x – 4

Each row has a coefficient of 3 and an x term, which can be modeled with 3 tiles and 1 tile, respectively.

The first row has a constant term of -1, which can be modeled with 1 tile in the Factor 1 spot.

The second row has a constant term of 4, which can be modeled with 4 tiles in the Factor 2 spot.

So, the configuration shows the correct factors (3x – 1) and (x + 4) for the sides of the model.

Step-by-step explanation:

if im wrong sorry

Answer:

D

Step-by-step explanation:

A function of x means that there can only be one value of y per x value.  Therefore, D does not match this because there are 4 values of y per x value (3).

Answer:

D

Step-by-step explanation:

Each x value can have only ONE y value

this means that there cannot be more than one of the same x value:

think of the x values as an input, each input has one output right?

ex:

input: 7

output:8

input:3

output:2

how is it possible that the same input has different outputs?

input: 5

output: 6,7

this does not make any sense, one input should only have one output hence, one value of x(input) should have only one value of y(output)

Answer:

[tex] \frac{9c + 160}{5} [/tex]

Step-by-step explanation:

C = 5(F - 32)/9

so we do a little algebra here

9C = 5F - 160

we move both side

5F - 160 = 9C

5F = 9C + 160

so in the end

F =

[tex] \frac{9c + 160}{5} [/tex]

a = 9

b = 160

c = 5

Answer:

[tex]F=\frac{9C+160}{5}[/tex]

Step-by-step explanation:

[tex]C=\frac{5(F-32)}{9}[/tex]

Multiply both sides with 9.

[tex]9C=5(F-32)[/tex]

Use distributive property.

[tex]9C=5F-160[/tex]

Add 160 to both sides.

[tex]9C+160=5F[/tex]

Divide 5 to both sides.

[tex]\frac{9C+160}{5}=F[/tex]

Answer:

x = [tex]-\frac{9}{2}[/tex]

Step-by-step explanation:

=> 3+2(2x+8) = 1

=> 3+4x+16 = 1

=> 4x+19 = 1

=> 4x = 1-19

=> 4x = -18

Dividing both sides by 4

=> x = [tex]-\frac{18}{4}[/tex]

=> x = [tex]-\frac{9}{2}[/tex]

Answer: -9/2

Step-by-step explanation:

3 + 2(2x + 8) = 1

3 + 4x + 16 = 1

19 + 4x = 1

4x = -18

x = -18/4 = -9/2

Answer: 84 people

Step-by-step explanation:

From the question, 240 people are going to a charity event and 3/5 of the guests have ordered chicken for their meals. This means (3/5 × 240) = 144 people ordered chicken. Since 144 people have ordered, the number of remain people left will be:

= 240 - 144

= 96 people.

Out of the remaining guests which is 96, 12.5% have ordered gluten free meals. This means (12.5% × 96) = 12 ordered gluten free meals.

The people who haven't ordered their meals yet will be:

= 96 - 12

= 84 people.

Using the appropriate arithmetic operations, the number of guests who haven't made an order yet is 126

Chicken orders = 3/5 × 240 = 144

Number left = 240 - 144 = 96

Gluten free meat = 12.5% × 144 = 18

Not yet ordered = 144 - 18 = 126

Therefore, the Number of guests who haven't made an order yet is 126

14x + 12.50y = 500

Answer:5

Step-by-step explanation:

rate of change is the same thing as slope (or m)

The required rate of change for the given equation y = 5x + 25 is 5.

Given that,
For the given equation y =5x +25 the rate of change is to be determined.

The slope of the line is the tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

The rate of change is defined as the change in value with the rest of the time is called rate of change.

Here,
The given equation,
y = 5x + 25
Differentiate the above equation with respect to x,
dy/dx = d(5x +25)/dx
dy/dx = 5dx/dx + d25/dx

dy/dx = 5      (since dx/dx =1 and d25/dx = 0)
here dy/dx is the slope of the equation or m or rate of change = 5

Thus, the required rate of change for the given equation y = 5x + 25 is 5.
