Four is equal to half of the sum of a number n and 22. What is the number n ? n = 30 n = 24 n=−14 n=−20.

Answer:

$30

Step-by-step explanation:

cost of tip is represented by 25 multiplied by 0.2:

25*0.2=5

add onto original price:

25+5=30

good luck :)

Answer:

$30 dollars

Step-by-step explanation:

Given the following question:
Total price = $25.00
20% tip

In order to find the answer, we find 20% of the 25-dollar haircut. Then we add that number to the original price of the haircut.

[tex]\frac{25\times20}{100} =25\times20=500\div100=5[/tex]
[tex]25+5=30[/tex]
[tex]t=30.00[/tex]

Total cost of the haircut was "$30.00 dollars."

Answer:

adjacent. x=55

Step-by-step explanation:

Answer:

Adjacent

x=55

Step-by-step explanation:

Vertical angles are made by the same lines but are opposite of each other. These angles are not opposite, and thus they are not vertical. Adjacent angles, on the other hand, share a common side and vertex. In other words, they touch. So, since these share both a common side and vertex, they are adjacent.

Additionally, the large-angle (that contains the smaller, adjacent angles) is a right angle, meaning that it has a measure of 90 degrees. So, if we know that part of the angle is 35 degrees, then the missing angle must be equal to 90-35. 90-35=55 degrees.

Answer:

x = 4

Step-by-step explanation:

Let's look at the ratio of the hypotenuse of both triangles:

25 : 5 = 25/5 = 5

we can see that the measures of the sides of the larger triangle are 5 times those of the smaller triangle.

Therefore, 3x + 8 = 4 x 5

⇒ 3x + 8 = 20

⇒ 3x = 20 - 8 = 12

⇒ x = 12 ÷ 3 = 4

⇒ x = 4

Answer:

x=4

Step-by-step explanation:

As you can see, these triangles are demonstrating a scale factor. It is upscaling by 5. To find out what x is equal to, we need to upscale the smaller side. In this scenario, we have to multiply 4 by 5. This will get you 20. Now we can make an equation.

20=3x+8

We can subtract 8 from both sides.

Now we have:

12=3x

now dividing 12 by 3, we get

x=4

The length of the line segment AB is √3 inches.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given, length of the diagonal of rectangle ABCD = 2 inches.

We have to find the length of the line segment AB.

We know, opposite sides of a rectangle are equal.

Thus, AB = CD

Now consider triangle DCB, which is a right angled triangle

In triangle DCB, angle C is 90°

Angle D is 30°

Angle B is 60°

By Pythagoras theorem,

sin θ = opposite/hypotenuse

sin 60° = CD/BD

√3/2 = CD/2

CD = 2(√3/2)

CD = √3

Thus, AB = CD = √3

Therefore, the length of the line segment is √3 inches.

Law of cosine is applicable to all the triangles. The value of the angle by which the boat turns is 39.195°.

Law of cosine helps us to find the third side of the triangle when 2 sides and an angle are known. It is formulated as,

[tex]c=\sqrt{a^{2}+b^{2}-2 a b \cdot \cos \gamma}[/tex]

a, b, c is the sides of the triangle and,

[tex]\gamma[/tex] = angle opposite c

A.)

Given to us

A boat traveled north for 28 miles, then turned x° southwest and traveled for 25 miles before stopping.

When it stopped, the boat was 18 miles from its starting point.

According to the given statements, sides and angles can be written,

a = 25 miles

b = 28 miles

c = 18 miles

[tex]\theta = x^o[/tex]

Substitute the values,

[tex]c=\sqrt{a^{2}+b^{2}-2 a b \cdot \cos \gamma}[/tex]

[tex]18=\sqrt{25^{2}+28^{2}-2(25)(28) \cdot \cos \theta}\\\\\theta = 39.195^o[/tex]

Hence, the value of the angle by which the boat turns is 39.195°.

B.)

Given to us

Starting at the dock, it travels 18 miles to the left, then 25 miles up and to the right, and then 28 miles down and back to the dock.

The angle between 25 miles and 28 miles is x degrees.

According to the given statements, sides and angles can be written,

a = 25 miles

b = 28 miles

c = 18 miles

[tex]\theta = x^o[/tex]

Substitute the values,

[tex]c=\sqrt{a^{2}+b^{2}-2 a b \cdot \cos \gamma}[/tex]

[tex]18=\sqrt{25^{2}+28^{2}-2(25)(28) \cdot \cos \theta}\\\\\theta = 39.195^o[/tex]

Hence, the value of the angle by which the boat turns is 39.195°.

Answer: 30 should be negative

Step-by-step explanation:

when having an equation like that, you must multiply -5 by 3, which equals to -15, then multiply-5 by 6 which then equals to -30. The correct equation should be -5(3+6)= -15+-30= -45

I think this should be correct, hope this helps!

Answer:

a) The negative was not distributed to the 6

b) -45

Step-by-step explanation:

This simplification uses the distributive property. This is when a factor outside of parentheses is multiplied by the factors within the parentheses. When using this property, if the factor outside the parentheses is negative, then that negative must be distributed to both factors within the parentheses.

Step-by-step explanation:

We know the area is 52 cm and that one length is 13cm. This means that in order to find the missing length, we need to divide 52 by 13. this gives us 4, meaning that the missing side is 4 cm.

Now we add 26 (Double of 13 because it is both sides) to 8 (Double of 4 because they are same lengthening sides)

Answer:

Step-by-step explanation:

A trapezoid is a four-sided polygon or a quadrilateral. It has one set of opposite sides which are parallel and a set of non-parallel sides.

(Therefore, statement 1 is incorrect and statement 4 is correct)

If the non-parallel sides of the trapezoid are equal in length, then it is called an isosceles trapezoid.  An isosceles trapezoid has a line of symmetry and both the diagonals are equal in length.

(Therefore, statement 3 is correct).

Statement 2 is incorrect as the diagonals are NOT perpendicular

Answer: The number of Beetiebots to decorate

Step-by-step explanation:

Area of a polygon can be derived from sum of area of its sub-parts. The area of the considered polygon is given by: Option C: 316 cm²

Some polygon are of standard shapes like rectangle, triangle, parallelogram etc, but some are not standard and can be of any shape. For finding their area, we divide that non-standard polygon in parts such that it gets divided in standard polygons.

Then, we get:

Area of non-standard polygon = sum of all standard polygons forming that initial polygon.

For the given case, dividing the polygon in the shapes whose area we know(which is called here as standard polygons), as shown in the figure attached below, we get:

Area of polygon = Sum of area of those composing parts.

Area of polygon =  Area of upper triangle ABC + Area of bottom rectangle BDEF

Height of ABC triangle = height of polygon - height of rectangle

Height of ABC = 18 - 14 = 4 cm

Base of ABC = length of BC = length of BD - length of CD = 21-10 = 11 cm

Thus, area of ABC = [tex]\dfrac{1}{2} \times base \times height = \dfrac{1}{2} \times 4 \times 11 = 22 \: \rm cm^2[/tex]

Area of rectangle BDEF = length times width = [tex]14 \times 21 = 294\: \rm cm^2[/tex]

Thus, area of polygon = Area of ABC + Area of BDEF = 22 + 294  cm²

Area of polygon = 316 cm² (option C)
