(50 POINTS) What is the sum of the interior angles of this traffic sign?

Answer:

12in

Step-by-step explanation:

15in squared - 9in squared is 144in and the square root of 144 is 12

Answer:

12 in

Step-by-step explanation:

Pythagoras' Theorem:  a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

let x = unknown side

Given:

Substituting the given values into the equation:

⇒ x² + 9² = 15²

⇒ x² + 81 = 225

⇒ x² + 81 - 81 = 225 - 81

⇒ x² = 144

⇒ x = √(144)

⇒ x = ±12

As the length is positive, x = 12 only.

Therefore, the length of the unknown side is 12 in.

Answer:

185.8-(25+1)*3

185.8-26*3

answer: 107.8

Answer:

We know what all of these signs mean, but what does 5^2 mean? I'll show you.

5^2, more commonly known as 5 squared, means a number times itself.

With that given info, we can multiply 5 times itself and find the answer.

[tex]5 * 5 = 25[/tex]

Put 25 in the blank.

Now you know what to do.

Incase you have more questions, I can answer them with PEMDAS.

Step-by-step explanation:

(2x - 3) + 8x = 180 (linear pairs)

10x - 3 = 180

10x = 180 + 3

10x = 183

x = 183÷10

x = 18.3

1 = 2x - 3

2 × 18.3 - 3

= 33.6

2 = 8x

8 × 18.3

146.4

Angle 1 + Angle 2 = 180

33.6. + 146.4. = 180

37 : 5 = 7,4

so 7 sets + [37 - (7x5)] = 2 left over

7 x 5 + 2 = 37

Answer:

The correct answer is C. 7 sets with 2 left over

Step-by-step explanation:

7 × 5 = 35

37 - 35 = 2

1 whole pan minus 5/8 the result is 3/8.

Answer:

22ft^3

Step-by-step explanation:

I took off the small bit to the bottom right first, then found the volume of the larger part (19). Then I added the volume of the smaller part (3). This gave me the answer of 22ft^3.

The volume of planter is 27 cubic feet .Therefore, amount of soil is needed to fill the planter will be 27 cubic feet.

Volume of the cuboid is the total space occupied by the cuboid in the three  dimensional space. It is calculated as:

Volume of cuboid = length × breadth × height

According to the given question

Planter is made up of two cuboids.

Therefore,

Amount of soil needed to fill the planter= volume of the planter

so, volume of the planter=(3×2×3)+(3×1×3)=27 cubic feet.

Hence, 27 cubic feet soil is need to fill the planter.

Answer:

z=7 and x=60

Step-by-step explanation:

well from the square that is combining the angles 1 and 2, they tell you that that is a right angle and you know that angle 2 is 38 so 90-38=52 which is the measurement of angle 1 so to find z, you would have to divide 38/-2 which is -19 and then add 12 so 12-19=-7 so z=7. so you know that one side =90 degrees so angle 3 must also =90 degrees because they are on the same line and a line is equal to 180, so all you have to do is reverse the operations in 1 1/2x to find x, so 1 1/2 or 3/2 divided by 90 is 60.

pls this took a lot of work and i kindly ask for brainliest.

Answer:

They would be 5%

Step-by-step explanation not for sure but what I did was add the correct numbers and added the incorrect numbers and It came out to 110 and 105 so I used 110/105 and looked at how much the percentage was and then when I got that I just took the percentage that would make it 100 percent. Hope it helps and sorry if it is incorrect I tried.

Answer:

I can't see the chart...

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

both lunes c and d are parrallel

line c =

∠1 + ∠4 = 240°

360 -240= 120 °

120/2 = 60°

as angle 2 and 3 are opposite each other they will have the same angle { 60°}

line d =

∠5 is 120° , ∠5 and ∠8 are opposites so ∠8 is equal to 120°

120 ×2 = 240

360-240=120°

120° / 2 = 60°

so ∠7 and ∠6 are 60°

both lines are parallel as the angles are corresponding

6 [tex]\frac{1}{12}[/tex] (6 1/12)

Question explanation:

First: 9 [tex]\frac{3}{4}[/tex] (9 3/4)

Convert any mixed number to fractions.

Then you initial equation becomes:

[tex]\frac{49}{4} - \frac{5}{2}[/tex]

(49/4 - 5/2)

Applying the fractions formula for subtraction,

(49 x 2) - (5 x 4)

4 x 2

98 - 20

8

= [tex]\frac{78}{8}[/tex]

(78/8)

Simplifying 78/8, the answer is:

9 [tex]\frac{3}{4}[/tex]

(9 3/4)

Second: 5 [tex]\frac{3}{4}[/tex] (5 3/4)

Convert any mixed numbers to fractions.

Reduce fractions where possible

Then your initial equation becomes:

Answer:

Coordinates involve two points. (x,y)

Too find a pair (coordinate), use the x and y lines on the graph and see where the point falls.

For example

Point A is number 1 on the y axis

number -4 on the x axis

So, you would write the coordinate out at

(-4,1)

The y axis values are the second point, so after you plot all of letters, use the y axis numbers and number them from least to greatest so you can find the mystery word.
