Answer:

x = 18

Step-by-step explanation:

the sum of any exterior angle is equal to the sum of any two interior angles

3x-11 + 5x+14 = 9x-15

8x + 3 = 9x - 15

3 = x - 15

x = 18

Answer:

6

Step-by-step explanation:

We need to solve the equation .The given equation is ,

→ 8 - 6x = -28

→ -6x = -28-8

→ -6x = -36

→ x = -36/-6

→ x = 6

Answer:

18

Step-by-step explanation:

Answer:

The slope of the line is 4.

Step-by-step explanation:

Recall that slope = rise over run:  rise / run.

From the table we see that if x changes from 0 to 4, a run of 4, y changes from -1 to 15, a rise of 16, the slope of this line must be

m = rise / run = 16/4 = 4

The slope of the line is 4.

Answer:

15,000cm^3

Step-by-step explanation:

Dividing the solid into 2;

Volume = Volume of A + Volume of B

Volume of Top prism (A) =25cm * 20cm * 10cm

Volume of Top prism (A) = 5000cm^3

Volume of bottom prism B = 20cm * 50 * 10

Volume of bottom prism B = = 10000cm^3

Volume of the figure = 5000 + 10000

Volume of the figure = 15,000cm^3

Answer:

-50 N

Step-by-step explanation:

125 - 75 = 50

left = negative

right = positive

The ball is going to be kicked to the left because the net force on the right is larger, and as you can see above, left = negative and right = positive. So the answer would be -50 N

Step-by-step explanation:

The actual length is 21 ft = 21 × 12 = 252 in

The model is [tex]\frac{1}{12}[/tex] of the actual size , then

model length = 252 ÷ 12 = 21 in

Answer: 30 fish

Step-by-step explanation:

A tank measuring 5 feet by 3 feet by 3 feet has a volume of 5*3*3 =45 cubic feet.

If there are 45 cubic feet of water in this tank, and each fish requires 1.5 cubic feet of water, the number of fish that can fit in the tank is 45/1.5 = 30.

Answer:

C

Step-by-step explanation:

The solution is: When the line passes through x = -6, the value of y is: -13.

Here, we have,

given that,

A line on a coordinate plane passes through the point (2, -7) and has a slope of 0.75.

we know the equation of straight line is: ;

y = mx + c

here, m = 0.75 and, (x,y) =(2, -7)

so, we get,

c = -7 - 0.75*2 = - 8.5

So, the equation of straight line is:

y = 0.75x - 8.5

now, when the line passes through x = -6,

we get,

y =  0.75* (-6) - 8.5

  = - 13

Hence, The solution is: When the line passes through x = -6, the value of y is: -13.

Answer:

There are 59,049 different ways of answering the exam.

Step-by-step explanation:

The first thing we need to count is the total number of selections, then we need to count the number of options for each one of these selections. The total number of combinations will be equal to the product between all the numbers of options.

Here, the selections are each one of the 10 questions, so we have 10 selections.

And each one of these selections has 3 options (true, false, blank)

So, we have 10 selections with 3 options each, then the total number of combinations will be:

C = 3*3*3*3*3*3*3*3*3*3 = 3^10

C = 59,049

Answer:

I think it should be 15...

Step-by-step explanation:

13 * 3 = 39

5 * 3 = 15

Sida "a" of the given triangle ABC is 15.

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.

Given Triangle ABC and Triangle XYZ are similar triangles. Hence,

AB /BC  = XY / YZ

Since, XY  =13 , YZ = 5, and AB = 39

Putting these values in the above equation

39/ a = 13/5

a = 15

Therefore, in the given triangle ABC side a  is 15.

Answer:

g(x) = 5ln (x-6)

Step-by-step explanation:

For us to have a vertical stretch, we need to multiply the whole function by the factor of stretching

Say for example, we stretched f(x) by a factor of a , we have the result as a•f(x)

Now, when we shift by a certain number of units, this is particularly a translation

The kind we have here is a horizontal translation

So by shifting 6 units left, we have it that we need to subtract 6 units from the x-coordinate value

Thus, we have the resulting function as;

g(x) = 5ln (x-6)

Answer:

non-negative

Step-by-step explanation:

Given

[tex]-4x\cdot y\cdot 0^6[/tex]

[tex]x , y > 0[/tex] --- Positive numbers

Required

The sign

[tex]-4x\cdot y\cdot 0^6[/tex]

First, we simplify the expression

[tex]0^6 = 0[/tex]

So:

[tex]-4x\cdot y\cdot 0^6 = -4x\cdot y\cdot 0[/tex]

The product of 0 and any factor is 0. So:

[tex]-4x\cdot y\cdot 0^6 = 0[/tex]

Since the result is 0, then the sign is non-negative
