Is the given sequence arithmetic? If so, identify the common
difference,
10, 20, 30, 40

Answer:

118

Step-by-step explanation:

The sum of the angles is 180 degrees

(3x + 13) + (x-8) +x = 180

Combine like terms

5x +5 = 180

Subtract 5 from each side

5x+5-5= 180-5

5x =175

Divide by 5

5x/5 = 175/5

x = 35

We want to find angle A

3x+13

3(35)+13

105+13

Answer:

-4.3s+0.6t-2.6

Step-by-step explanation:

Add like terms:

-3.5t+4.1t-4s-0.3s+4.5-7.1

= 0.6t-4.3s-2.6

= -4.3s+0.6t-2.6

Answer:

Only point C. (9,4)

Step-by-step explanation:

To check if the points are inside the region of the inequalities, we just need to use the values of the point in each inequation, and if the point satisfy all inequations, the point is inside the region.

point A = (1,8): s = 1 and t = 8

first inequation: s<24 - 0.66t

1 < 24 - 0.66*8

1 < 18.72 (true)

second inequation: s>12 - t

1 > 12 - 8

1 > 4 (false)

So point A is not inside the region.

point B = (-9,21): s = -9 and t = 21

As we can see from the fourth inequation, the s value needs to be greater than 0, and point B has s negative, so point B is not inside the region.

point C = (9,4): s = 9 and t = 4

first inequation: s<24 - 0.66t

9 < 24 - 0.66*4

9 < 21.36 (true)

second inequation: s>12 - t

9 > 12 - 4

9 > 8 (true)

third inequation: s< 30 - t

9 < 30 - 4

9 < 26 (true)

fourth inequation: s>0

9 > 0 (true)

fifth inequation: t>0

4 > 0 (true)

As all conditions are true, point C is inside the region.

point D = (30,10): s = 30 and t = 10

first inequation: s<24 - 0.66t

30 < 24 - 0.66*10

30 < 17.4 (false)

So point D is not inside the region.

r=3 ft

Step-by-step explanation:

it is similarity of two triangles

one

perpendicular side=10 ft

base=10/2=5 ft

second

perpendicular side=10-4=6 ft

Base r=?

[tex]\frac{r}{5}=\frac{6}{10}\\r= \frac{6}{10} \times 5=3~ft[/tex]

Answer:

Exactly 1 solution

Step-by-step explanation:

First we must disrupte3y+27=12y+13

Next we switch one number to the other side27=9y+13

Now we must switch the other number14=9y

Now we must solve by dividing 14 by 9y=1.555

This is one solution, so we now have our answer.

The equation has only one solution. Then the correct option is A.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equations are given below.

3y = -6x + 9

y = -2x + 3       ...1

y = -6x + 9      ...2

From equations 1 and 2, then we have

-2x + 3 = -6x + 9

4x = 6

x = 6/4

x = 1.5

Then the value of the variable 'y' is calculated as,

y = -2x + 3

y = -2(1.5) + 3

y = - 3 + 3

y = 0

The solution of the equation y = -2x + 3 and y = -6x + 9 will be (1.5, 0). Then the equation has only one solution. Then the correct option is A.

Answer:

5 to the power of -2

Step by Step explanation:

Because you are diving, you need to subtract the powers.

For example, you subtract 10 from 12 to get -2

The 5 remains the same so the answer should be 5 to the power of -2

Answer:

[tex]log_{4}[/tex] (64)=x

Step-by-step explanation:

The logarithmic form of the equation Log₄( 64 ) = x.

The logarithm of a number is the power or index, a certain base will be raised to give that number.

Analysis:

4 is the base, x is the index and 64 is the number. so the logarithm of 64 to base 4 is 3 which can be written as ㏒ = x

in conclusion, the equation 4x can be written in a logarithmic form as  

=  Log₄( 64 ) = x.

Answer:

r = 11

Step-by-step explanation:

Given

The above table

y = rx

Required.

Find the constant of proportionality.

To find the constant of proportionality, we simply test the values of y and x in the given formula.

Using y = rx

Make r the subject of formula by dividing both sides by x

y/x = rx/x

y/x = r

r = y/x

From the above table of data;

When x = 2, y = 22

So, r = 22/2

r = 11

When x = 7, y = 77

So, r = 77/7

r = 11

When x = 9, y = 99

So, r = 99/9

r = 11

Notice that r maintains the value of 11 all through.

Hence, the constant of proportionality, r for the above data is 11

Answer:

r = 11

Answer:

115Gallons

Step-by-step explanation:

1. Calculate the Volume - Volume of a cylinder is done by this formula, V=π*R^2*H.

3.14x1.5^2x4.5=V

V=31.79ft^3

2. Find the amount of Gallons it can hold total - V=31.79 Now per 1ft^3 its roughly 7.5 gallons. 31.79x7.5=238.44gallons

3. Find the amount occupied by the water currently in the barrel - So we need the middle point so we have something to go off of, now 2.5ft isn't half of 4.5, 2.25 is. So 238.44/2=119.22Gallons. Now 2.5 is 53.4% the difference is 3.4. So we need to take 119.22Gallons*.034=4.05 now add that to the 119.22 and you get 123.27 gallons used

4. How much is left over? - Take 238.44-123.27=115.17 more Gallons that the barrel can hold.
