Answer:

B: BC ≅EC

Step-by-step explanation:

You know that the two angles starting in C are congruent (they're opposite by vertex C).

Given that the B angle and the E angle are congruent, in order for the two triangles to be congruent by A(ngle)S(ide)A(ngle) you want the side inbetween to be congruent. That is BC and EC. Option B

Step-by-step explanation:

the general slope intercept form is

y = ax + b

a is the slope. a parallel line must have the same slope.

in our case here it is -3.

b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).

we get b by using the point coordinates in the equation and solve for b :

-4 = -3×-9 + b = 36 + b

b = -40

so, the full equation of the parallel line is

y = -3x - 40

P(Neither 9th grade)=16/28*16/28=16/28*16/28=(16/28)^2=256/784≈0.3265

Answer:

The probability that neither of the students selected are 9th  graders is about 0.33.

Step-by-step explanation:

Pls give brainliest

Probabilities are used to determine the chances of events

The probability that neither of the students is a 9th grader is 0.33

From the table, the number of students that are not 9th graders are:

[tex]N9 =9 + 7[/tex]

[tex]N9 =16[/tex]

The total number of students is:

[tex]Total =12 + 9 + 7[/tex]

[tex]Total =28[/tex]

The probability that neither of the students is a 9th grader is calculated as follows

[tex]P =P(N9) \times P(N9)[/tex]

So, we have:

[tex]P =\frac{16}{28} \times \frac{16}{28}[/tex]

Multiply

[tex]P =\frac{256}{784}[/tex]

Divide and approximate

[tex]P =0.33[/tex]

Hence, the probability that neither of the students is a 9th grader is 0.33

Answer:

y = - 3x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + y - 1 = 0 ( subtract 3x - 1 from both sides )

y = - 3x + 1 ← in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, thus

y = - 3x + c ← is the partial equation

To find c substitute (1, 4) into the partial equation

4 = - 3 + c ⇒ c = 4 + 3 = 7

y = - 3x + 7 ← equation of line in form y = mx + c

Answer:

x = 9

Step-by-step explanation:

78 - 2x = 87 - 3x

3x - 2x = 87 - 78

x = 9

x = 9

Step-by-step explanation:

=> 78-2x= 87 -3x

=> 78-87=-3x+2x

=> -9 = -x

Answer:

4.95

Step-by-step explanation:

The volume of the rectangular prism is 16.2 ft³.

The volume of any object defined the capacity of it, how much it can hold something is called its volume.

Given is rectangular prism, we need to find the volume of the same,

So, we know that the volume of a rectangular prism is the product of its dimensions.

V = length × width × height.

[tex]V = 1\frac{1}{5} \times 4\frac{1}{2} \times 3[/tex]

[tex]V = \frac{6}{5} \times \frac{9}{2} \times 3[/tex]

V = 162/10

V = 16.2

Hence, the volume of the rectangular prism is 16.2 ft³.

Answer:

8 or 9

Step-by-step explanation:

Your primary equation that they gave you is ?b and has to be greater than ?a  7 x ?a =42

So your answer to ?a is 7 because 7 x 7 =42   therefore your answer to ?b has to be 8 or above.  

the next part of your problem states that it is a whole number UNDER 10....  this limits your possible answer to either 8 or 9.
