(answer choices are in the picture)

Answer:

$260 because if there are two children you do 2x25=50 then 2x3=6 then 6x35=210 and then add 50 and 210 and you get 260.

Answer:

$260

Step-by-step explanation:

One Adult Ticket= $35

One Child Ticket= $25

Let c represent children and a represent adult

1)Cost for children = [tex]2c*25= $50[/tex]

2)Formula to find number of adults = [tex]2c+3=6a[/tex]

3)Cost for adults = [tex]6a*35=210[/tex]

4) Cost for group = [tex]210+50=260[/tex]

Answer = $260

A number line is a straight line drawn horizontally where the numbers are placed at an equal intervals.

Given is a number line.

A point is marked in between -3 and -4.

In between -3 and -4, the region is equally spaced in to 4 parts.

The point is market at 1/4 distance from -3.

So the point can be written as -3 1/4.

Answer:

Step-by-step explanation:

Using proportions, it is found that the table will be 110 feet long when the carpenter builds it.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In the drawing, 0.75 inches represent 11 feet. The drawing is of 7.5 inches, and the real dimension is of d, hence the rule of three is given by:

0.75 inches - 11 feet.

7.5 inches - d feet

Applying cross multiplication:

0.75d = 7.5 x 11

d = 7.5 x 11/0.75

d = 110.

The table will be 110 feet long when the carpenter builds it.

The scale model of the table would ensure that the actual table is bigger than the scale model

The length of the table would be 110 feet

The scale model is given as:

Ratio = Scale : Actual

So, we have:

Ratio = 3/4 inches : 11 feet

For a table of 7 1/2 inches, we have the following ratio

Ratio = 7 1/2 inches : Actual

Equate both ratios

7 1/2 inches : Actual = 3/4 inches : 11 feet

Express as decimals

7.5 inches : Actual = 0.75 inches : 11 feet

Rewrite as:

7.5 : Actual = 0.75 : 11 feet

Express as fraction

Actual/7.5 = 11 feet/0.75

Multiply both sides by 7.5

Actual = 7.5 *  11 feet/0.75

So, we have:

Actual = 110 feet

Hence, the length of the table would be 110 feet

Step-by-step explanation:

9 ft / 12 = 0.75 ft

0.75 ft × 12 in. / ft = 9 in.

Answer: 0.75 ft or 9 in.

9 feet

when divided equally, the length of each piece.

9/12

when simplified= 3/4

in decimal form= 0.75ft

The countertop is  8.37 square metersStep-by-step explanation:LetL &gt; the length of the countertopW &gt; the width of the countertopwe know

Answer:

19.83 square meters

Step-by-step explanation:

So, if we are finding the area of a rectangular countertop, we need to multiply the length by the width.          A=lw    l=length    w=width

First, we multiply the length and width of the countertop (13 and 5).

13x5=65 square feet              65 is the area of thecountertop in feet.

Next, we have to multiply that by 0.305 to convert it into meters.

65*0.305=19.825 square meters       If we round it, its 19.83 square meters.

Answer:

<1=28, <2=62

Step-by-step explanation:

You know that the large triangle is 180 and there is a smaller triangle that is also 180. You are also provided an angle is 90 and another is 62.

90+62=152.

180-152=28. So, angle 1=28.

28+90=118.

180-118=62

The value of measure of angle ∠1 is,

⇒ ∠1 = 28°

And, The value of measure of angle ∠2 is,

⇒ ∠2 = 118°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Now, For definition of angles of triangles;

We get;

⇒ 62° + 90° + ∠1 = 180°

⇒ 152° + ∠ 1 = 180°

⇒ ∠ 1 = 180° - 152°

⇒ ∠1 = 28°

And, Sum of two interior angles of triangle is equal to an exterior angle of triangle.

Hence, We get;

⇒ ∠2 = ∠1 + 90°

⇒ ∠2 = 28° + 90°

⇒ ∠2 = 118°

Thus, The value of measure of angle ∠1 is,

⇒ ∠1 = 28°

And, The value of measure of angle ∠2 is,

⇒ ∠2 = 118°

(If you need it explained in words just let me know)

The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

The two angles are said to be supplementary angles if their sum is 180 degrees.

By the above property of angle, the equation is written as,

x + 100° + 3x = 180°

Simplify the equation, then we have

x + 100° + 3x = 180°

4x = 80°

x = 80° / 4

x = 20°

The equation using supplementary angles is x + 100° + 3x = 180°. Then the value of 'x' is 20°.

[tex]400x^{2}[/tex]

Step-by-step explanation:

Factor the coefficent which is just the number parts of these terms.

(800 and 1200)

you find that both have a factor of 400 in common but many other numbers as well. You choose the highest number because you need to find the greatest common factor.

Then, you look at the variables. y is immediately incorrect since one of the terms do not have y. You look at x. Again, you can factor [tex]x^{2} and x^{3}[/tex] into x*x  and x*x*x. Since there can only be 2 x in common, your variable gcf is [tex]x^{2}[/tex]

Answer:

The machine takes 25 minutes to make 5 chairs. It would take the machine 160 minutes to make 32 chairs.

Step-by-step explanation:

Divide 2 chairs by 10 minutes to find the amount of chairs made per minute.

2/10 = 0.2 chairs per minute

Divide 5 chairs by 0.2 chairs per minute to find how much time it takes to make 5 chairs.

5/0.2 = 25 minutes

It takes the machine 25 minutes to make 5 chairs.

Divide 32 chairs by 0.2 chairs per minute to find how much time it takes to make 32 chairs.

32/0.2 = 160 minutes

It takes the machine 160 minutes to make 32 chairs.
