Solve –3(2 – 5w) = 9w + 66 for w.

Answer:

0

Step-by-step explanation:

The formula gives you a relation between S and n. For every n, you can perform the calculation and obtain an S.

So, for n=0 we get 0/2 (0+1) which equals 0. So (0,0) is an (n,S) pair.

Answer:

13.72 cubic units

Step-by-step explanation:

The equation below shows the total volume (V), in cubic units, of 5 identical boxes with each side equal to s units:  V = 5s3  

If s = 1.4 units, what is the value of V?

Substitute s = 1.4 into V = 5s³ = 5(1.4)³ = 13.72 cubic units.

Answer:

wats part A?

Step-by-step explanation:

Give me the data:)

The correct answer is C = 9.

Step by step:

Subtract 12 - 9 = 3

3 + 9 = 12.

It’s that simple. Hold this helps!

The value of c is 9 makes the equation true.

It is given that the equation 12 - 9 + c =12.

It is required to find the value of c that makes the equation true.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

We have a linear equation in one variable:

12 - 9 + c = 12

-9 + c =0   (subtract 12 on both sides)

c = 9   ( add 9 on both sides)

Thus, the value of c is 9 makes the equation true.

A ray is a part of a line that has one endpoint and goes on infinitely in only one direction you can't measure the length of a ray ..hope this helps

Step-by-step explanation:

The endpoint of a ray is the starting point from which the ray extends indefinitely in one direction. It's different from a line, which has no endpoint as it extends indefinitely in both directions.

In mathematics, specifically in geometry, a ray is a part of a line that starts at a particular point, known as the initial point, origin, or endpoint, and extends indefinitely in one direction. This is different from a line, which extends in both directions. When you draw a ray, you put an arrow on one end to show that it continues without end in that direction. The

end point of a ray is essentially the starting point from which the ray extends. For example, if you have a ray AB, point A is the endpoint and the ray extends towards point B but beyond it indefinitely. Thus, a ray has only one endpoint, not two.

Step-by-step explanation:

You will pay the whole price of the item which is p or 1p. Then you will add 4% tax or 0.04p. So the total will be 1p + 0.04p = 1.04p.

A. 12 in

We know that the sports stadium is 180 ft tall and that in the scale model there is 2 in for every 30 ft. If we divide 180 by 30 we get 6. There is 2 in for every 30 ft, so the answer would be 6 x 2 or 12 in.

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

If 2 inches = 30 feet and the height of the sports stadium is 180 feet.

The height of the sports stadium in scale model in inches is 12 inches.

Option C is the correct answer.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

In 5 minutes a machine can cut 10 potato

In 1 minute a machine can cut 2 potato.

We have,

30 feet = 2 inches

Divide both sides by 30.

1 feet = 2/30 inches

Now,

1 feet = 2/30 inches

Multiply 180 on both sides.

180 feet = 180 x 2/30 inches

180 feet = 6 x 2 inches

180 feet = 12 inches

Thus,

If 2 inches = 30 feet and the height of the sports stadium is 180 feet.

The height of the sports stadium in scale model in inches is 12 inches.

Answer:

see explanation

Step-by-step explanation:

Since AC = BC then ΔABC is isosceles with base angles

∠BAC =∠ABC, thus

3x + x = 70

4x = 70 ( divide both sides by 4 )

x = 17.5

----------------------------------------------------

∠ADC is an external angle of ΔABD and the external angle is equal to the 2 opposite interior angles, hence

y = 70 + x = 70 + 17.5 = 87.5

Answer:

37 Chairs

Step-by-step explanation:

Last week she set up 22 chairs.

This week, that amount was 15

Add those together, and you have 37.

Gina set up a total of 37 chairs in the past two weeks.

To find the total number of chairs Gina set up in the past two weeks, we need to add the number of chairs she set up last week to the number of chairs she set up this week.

Answer:

[tex]d\geq 5\\\\w<7\\\\a\leq 4[/tex]

Step-by-step explanation:

For each you have to look at three things - the direction of the arrow, if the circle is filled in, and the number the point is located on.

If the arrow is pointed right and the numbers are increasing, you use the greater than sign (>).

If the arrow is pointed left and the numbers are decreasing, you use the less than sign (<).

If the circle is filled in, it means you use the greater than or equal to (≥) less than or equal to signs (≤).

For the first inequality, the arrow is pointing right, the circle is filled in, and the point is on five so the inequality is [tex]d\geq 5[/tex].

For the second inequality, the arrow is pointing left, the circle is not filled in, and the point is on seven so the inequality is [tex]w<7[/tex].

For the third inequality, the arrow is pointing left, the circle is filled in, and the point is on four so the inequality is [tex]a\leq 4[/tex].

Step-by-step explanation:

If the wave length is 100m and it goes at a speed of 200m/s then it will only take 0.5 seconds because 100 is half of the speed of 200

Answer:

C

Step-by-step explanation:

The formula we use to solve this would be:  [tex]T=\frac{\lambda}{v}[/tex]

Where

T is the period in seconds

[tex]\lambda[/tex] is the wavelength in m, and

v is the speed of the wave in m/s

We have [tex]\lambda[/tex] equal to 100, and v = 200 m/s. Plugging these into the equation, we get the period:

[tex]T=\frac{\lambda}{v}\\T=\frac{100}{200}\\T=0.5[/tex]

C is the right answer.

Answer:

= -43

Step-by-step explanation:

Evaluating the expression;

(–1)8 + (–1)7 + –16 + –14 – (–1)2

We can use Bodmas

We remove the brackets first

(–1)8 + (–1)7 + –16 + –14 – (–1)2

We get

-8 + - 7 + -16 + -14 - -2

but; - × + = - and - × - = +

Thus;

-8 - 7 - 16 - 14 + 2

= -8 -7 - 16 - 12

Answer:

528

Step-by-step explanation:

x = 480

1.1 x = 480 * 1.1

480 + 48 = 528

Timothy traveled 528 miles using the gasoline from Smith's Station, which is 10% farther than the 480 miles he traveled with gasoline from Jack's Station.

To calculate how far Timothy traveled using the gasoline from Smith's Station, we need to determine what 10% more than the 480 miles he traveled using gasoline from Jack's Station is. First, let's find 10% of 480 miles:

Now, let's add this additional distance to the original 480 miles to find the total distance traveled with gas from Smith's Station:

Therefore, Timothy traveled 528 miles on a tank of gas from Smith's Station.

Third option

x ≠2 and x cannot be any value for which v(x) = 0

Step-by-step explanation:

In this problem we are asked to find the domain of the function

[tex](UoV)(x)[/tex]

We know that [tex](UoV)(x) = U(V(x))[/tex].

We know that:

Domain of U(x) is all real numbers except x = 0

Domain of V(x) is all real numbers except x = 2.

Then the domain of the composite function U(V (x)) is:

all real numbers except x = 2. (since x = 2 does not belong to the domain of V(x) and all values of x for which V(x) = 0 (since x = 0 does not belong to the domain of U(x))

Finally the domain of [tex](UoV)(x)[/tex]) is:
