Answer:

[tex]x = 56[/tex]

Step-by-step explanation:

Use tangent function.

[tex] \tan(x) = \frac{18}{12} [/tex]

Take the arctan

[tex] \tan {}^{ - 1} ( \frac{18}{12} ) [/tex]

which is about

0.98279372.

Convert from radians to degrees in you will get

56 degrees.

Answer:

Step-by-step explanation:

You can solve this by using trigonometry and the formula SOH CAH TOA. You're looking for an angle that is adjacent (next to) 12, and opposite 18. Therefore, you will needed to use TOA, which stands for tangent = opposite/adjacent.

With substitution, this gives you tangent  = 18/12. 18/12 is equal to 1.5. Because we are looking for an angle we need to use the tan^-1 (tan to the power of -1) button on our calculator. Tan(1.5)^-1 equals 56.31 to 2dp.

Hope this helps!

Answer: [tex]h=8.33\ cm[/tex]

Step-by-step explanation:

Given

The length of a cuboid is [tex]l=15\ cm[/tex]

breadth is [tex]b=12\ cm[/tex]

Total surface area is [tex]S.A.=900\ cm^2[/tex]

Surface area is given by [tex]2(lb+hl+bh)[/tex]

Insert the values

[tex]\Rightarrow 900=2(15\times 12+15h+12h)\\\Rightarrow 450=225+27h\\\Rightarrow 225=27h\\\Rightarrow h=8.33\ cm[/tex]

Answer:

Answer:

Top left Equation:  [tex]\frac{2}{3} + (- 2 \frac{1}{3} ) = - 1 \frac{2}{3}[/tex]

Step-by-step explanation:

You start at 2/3, or the left side.

Since the line is directing left, you are subtracting, or adding a negative.

If you see, you are moving 7 - 1/3s to the left

7 x 1/3 = 7 / 3

7 / 3 = 2 1/3

And 2/3 + (-2 1/3) = -1 2/3

Answer:

The ratio of any two corresponding lengths in two similar geometric figures.

Step-by-step explanation:

You can see immediately that the length of each of the sides in triangle DEF is equal to the length of the corresponding side in ABC multiplied by “a”.

If you divide the length of DE by the length of AB:

a^2/a =a.

You get a scale factor of “a”

Answer:

x = 12 degree

Step-by-step explanation:

3x + 19 + 5x = 115 degree (sum of two interior opposite angles are equal to the third side)

Step-by-step explanation:

Answer:

3 ounces

Step-by-step explanation:

there are two ways that the answer to this question can be determined

Method 1

If the regular bottle  Holds 75% less in it, it means that the regular bottle holds 25%(100 - 75)

Ounces the regular bottle holds = 25% x 12

0.25 x 12 = 3

Method 2

Determine the value of 75%

75% x 12

0.75 x 12 = 9

Since the regular bottle  Holds 75% less in it, subtract the value of 75% from 12 ounces

12 - 9 = 3

Answer:

Step-by-step explanation:

• no solution:

3x+9+4x+x = 8x + 9

• one solution:

3x+9+4x+x = 7x + 11

• infinitely many solutions:

3x+9+4x+x = 8x + 11

Step-by-step explanation:

Answer:

[tex] A)\displaystyle2 < x < 3[/tex]

Step-by-step explanation:

A compound inequality is an inequality that combines two simple inequalities

we are given that

[tex] \displaystyle 4x - 4 < 8 \ \: \text{and} \: \: 9x + 5 > 23[/tex]

solving x for the first equation:

[tex] \displaystyle 4x - 4 < 8[/tex]

add 4 to both sides:

[tex] \displaystyle 4x < 12[/tex]

divide both sides by 4 and since we are dividing both sides by a positive number the inequality won't swap

[tex] \displaystyle x < 3[/tex]

solving x for the second equation:

[tex] \displaystyle 9x + 5 > 23[/tex]

cancel 5 from both sides:

[tex] \displaystyle 9x > 18[/tex]

divide both sides by 9 and since we are dividing both sides by a positive number:

[tex] \displaystyle x > 2[/tex]

therefore by combining the equations we obtain:

[tex] \displaystyle\boxed{2 < x < 3}[/tex]

hence,

our answer is A)

Answer:

25 meters .

Step-by-step explanation:

The actual width of the rectangle is 24.5 meters.

The area of rectangle equals the base(width) times the height.

A = w × h

Given

Area of rectangle = 500 square meters.

Length of rectangle = 4x - 3 meters

Width of rectangle = 2x + 6 meters

Area of rectangle = length × width

500 = (4x - 3) (2x + 6)

⇒ 500 = [tex]8x^{2}+24x-6x-18[/tex]

⇒ 500 = [tex]8x^{2}+18x-18[/tex]

⇒ 500 = [tex]2(4x^{2}+9x-9)[/tex]

⇒ [tex]\frac{500}{2}=4x^{2}+9x-9[/tex]

⇒ [tex]250=4x^{2}+9x-9[/tex]

⇒ [tex]4x^{2}+9x-9-250=0[/tex]

⇒ [tex]4x^{2}+9x-259=0[/tex]

⇒ 4x(x + 7) -37(x + 7) = 0

⇒ (x + 7) (4x - 37) = 0

⇒ x = -7, x = [tex]\frac{37}{4}[/tex]

-7 is not satisfied because it is a negative number.

By substituting x = [tex]\frac{37}{4}[/tex] in width of rectangle

Actual width of rectangle = 2x + 6

= 2( [tex]\frac{37}{4}[/tex]) + 6

= [tex]\frac{37}{2}[/tex] + 6

= [tex]\frac{37+12}{2}[/tex]

= [tex]\frac{49}{2}[/tex]

= 24.5 meters

Hence, the actual width of the rectangle is 24.5 meters.

Answer:

It is D, I think it’s because the letters need to be around in the same order

The angle corresponding to each other of different triangle are equal.

"Similar triangles are triangles that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion".

Here given,

Answer:

31 questions, but it's impossible to score 75%.

Step-by-step explanation:

It's impossible to get exactly a score of 75% out of 42 questions. However, you can get the next closest percentage, which is rounded up to 74% with 31 questions right out of 75.

This is because 31 / 42 = 0.738... You can round 0.738 to 0.74. Then multiply 0.74 by 100, which gives you 74. This means the closest score you can get to 75 is 74% with 31 questions.

You can also score 76% with 32 questions right out of 42 questions. This is because 32 / 42 = 0.761... You can round 0.761 to 0.76. Then multiply 0.76 by 100, which gives you 76.
