The top two are 3 and 4.

The bottom two are both 6.

Step-by-step explanation:

You see how the top one is a 7, you divide it into 2 in any way.

Like how I did 3 and 4 which would equal to 7, it can also be 6 and 1 etc..

And for the bottom one it doesn't change.

Answer:

The value of [tex]x[/tex] :

[tex]x = 16[/tex]

Step-by-step explanation:

-To find the value of x, you need to use [tex]3x + 18[/tex]  and [tex]66\textdegree[/tex] written as in equation like this:

[tex]3x + 18 = 66[/tex]

-Then, you solve for it:

[tex]3x + 18 = 66[/tex]

[tex]3x + 18 -18 = 66 -18[/tex]

[tex]3x = 48[/tex]

[tex]\frac{3x}{3} = \frac{48}{3}[/tex]

[tex]x = 16[/tex]

So, therefore the final answer is [tex]x = 16[/tex].

Answer:

B

Step-by-step explanation:

Graph B represents a linear function.

Notice that graph D also shows a line, but it is not the graph of a function, since it doesn't pass the vertical line test for functions.

Graph A shows a quadratic function, and graph C shows likely an exponential function. It is graph B the one that is linear, and a function as well.

Answer: It is B.

Step-by-step explanation:

A is a quadratic function

B is a linear function because it is a straight line and every input has exactly one output.

C is a is not straight

D failed the vertical line test.

Answer :

9 sides

Explanation:

Step 1

Since the interior angle is 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.

Step 2

Method 2: Since the exterior angle is 140°

The sum of the interior angles = (2n - 4) × right angles.

So 140n =(2n - 4) ×right angles, or we can also say

140n =(2n - 4) × 90

140n = 180n - 360

40n = 360

Divide both sides of the equation by 40

n = 9 sides.

n = 9 sides.Hence the number of sides is 9 sides.

Answer:

f(3) = 63

Step-by-step explanation:

f(x) = 4^x-1;

Let x =3

f(3) = 4^3 -1

     = 64-1

     =63

Answer:

f(3)=16

Step-by-step explanation:

This question asks us to find f(3). We have to find what f(x), or y is, when x is equal to 3.

f(x)=4^x-1

Substitute 3 in for x.

f(3)=4^3-1

First, subtract what is in the exponents.

f(3)=4^2

4^2 is the same as multiplying 4, 2 times.

4^2=4*4=16

f(3)=16

Answer:

a.  x = 61 degrees.

Step-by-step explanation:

By the External angle of a Triangle Theorem:

116 = 55 + x

x = 116 - 55

x = 61 degrees.

Answer:

a) 61

Step-by-step explanation:

The classic way to do this is to subtract 116 from 180, then adding that result to 55 and subtracting this second result from 180.

But another way that I have discovered is to subtract 55 from 116. You will get the same answer of 61.

Answer:

$1193

Step-by-step explanation:

First we need to find the volume of one pedestal, that has a cylindrical part and a cubic part.

The volume of the cylindrical part is:

V1 = pi * r^2 * h

The radius is half the diameter, so r = 8/2 = 4 in. So the volume is:

V1 = pi * 4^2 * 3 = 48pi in3

The volume of the cubic part is:

V2 = side^3 = 8^3 = 512 in3

So the total volume of the pedestal is:

V = V1 + V2 = 512 + 48pi in3

If we want 15 pedestals, we have a total volume of:

15 * V = 15 * (512 + 48pi) = 9941.9467 in3

As each cubic inch costs $0.12, we just need to multiply the volume by the price to find the total cost:

Cost = 9941.9467 * 0.12 = $1193.03

Rounding to the nearest dollar, we have a cost of $1193

Answer:

7/13 or 54% or about 0.54

Answer:

Step-by-step explanation:

the volume of a rectangle is length x width x height, so the volume of the first rectangle is 2700.

the square has a length and width of 15 with a missing height. because they have the same volume, you can plug in the length and width of the square with the volume of the prism to find the height

v = length x width x height

2700 = (15)(15)h

2700/225 = h

the height is 12

Answer:

Therefore the expression that finds the coterminal angles is:

[tex]coterminal = 126\º \pm 360[/tex]

Step-by-step explanation:

Coterminal angles are angles that finish at the same line. Therefore in order to find the coterminal angles with 126º we need to add or subtract a angle of 360º. So the expressions are:

coterminal angle = 126º + 360º = 486º

coterminal angle = 126º - 360º = -234º

Therefore the expression that finds the coterminal angles is:

[tex]coterminal = 126\º \pm 360[/tex]

Answer:

126° + (720n)°, for any integer n or D on edge :)

Answer:

$56.25

Step-by-step explanation:

We know that Max has just enough money to buy 3 tickets that each cost $18.75, so let's write the expression:

18.75 * 3

We just solve this by multiplication:

18.75 * 3 = $56.25

Max saved $56.25.

Answer:

$56.25

Step-by-step explanation:

His savings were equal to the cost of 3 tickets, therefore

Savings = 3 × 18.75

Savings = 56.25

Answer:

There are no tables, but... I made a quick graph.

Step-by-step explanation:

y=2x-1 means that you start at (0,-1), one down from the origin (0,0). From there, you go up 2 and right one (1, 2), as well as down 2 and left 1 (-1, -2), since the slope is 2 (or [tex]\frac{2}{1\\}[/tex]). The lines continues in both directions, of course.

The table for the equation is y = 2x - 1

x y

0 -1

1 1

2 3

To determine which table represents the equation y = 2x - 1, we substitute the values of x into the equation and check if the resulting y values match those given in the table.

Substitute the values 0, 1, and 2 into the equation y = 2x - 1 and calculate the corresponding y-values:

For x = 0:

y = 2(0) - 1

y = 0 - 1

y = -1

For x = 1:

y = 2(1) - 1

y = 2 - 1

y = 1

For x = 2:

y = 2(2) - 1

y = 4 - 1

y = 3

The corresponding y-values for x = 0, 1, and 2 are -1, 1, and 3, respectively.

n+(n+1)+(n+2)+(n+3)=34

4n+6=34

4n=28

n=7 ANSWER: The smallest integer is 7

CHECK:

7+8+9+10=34

34=34

the least of the four consecutive integers is 7.

Let's denote the four consecutive integers as x, x + 1, x + 2, and x + 3.

According to the given information, the sum of these four consecutive integers is 34:

x + ( x + 1 ) + ( x + 2 ) + ( x + 3 ) = 34

Simplifying the equation:

4 x + 6 = 34

Subtracting 6 from both sides:

4 x = 28

Dividing both sides by 4:

x = 7

The four numbers are 7, 8, 9, 10

Therefore, the least of the four consecutive integers is 7.

Answer: 1/4 full.

Step-by-step explanation:

The question is asking for how much gas will be left in the tank after 2/3 of the gas in the tank is used.

There is currently 3/4 of the tank remaining.

To find 2/3 of 3/4, you can multiply the fractions together.

Do this by multiplying both numerators and both denominators:

[tex]\frac{2}{3} *\frac{3}{4} = \frac{2*3}{3*4} = \frac{6}{12}[/tex]

Then, subtract 6/12 from 3/4. You can do this by simplifying the first fraction to 2/4 (divide both the numerator and denominator by 3).

3/4 - 2/4 = 1/4

There will be 1/4 of the tank left.

Answer:

1/4

Step-by-step explanation:

We have 3/4 of a tank

We will use 2/3 of the  gas in the tank

See the diagram  That will leave us 1/4

Mathmatically

3/4*2/3 = 2/4 =1/2  this is the amount that is used

Subtract this from the amount in the tank

3/4 -1/2

3/4 -2/4 = 1/4

This is the amount that is left in the tank

B, 5x - 3 = 12

Step-by-step explanation:

3 less means subtracting, it's going to be -3.

It says 3 less than five times a number, meaning we don't know the number, so we can put it as x.

3 less means your subtracting from something, which would make it 5x - 3.

Finally, they state that it equals 12, making the equation 5x - 3 = 12.
