Answer:

x=8°

Step-by-step explanation:

If two sides are equal than there angles are also equal.

2x+40+5x+22+5x+22=180

12x+84=180

12x=180-84

12x=96

x=96/12

x=8°

Answer:

$760

Step-by-step explanation:

Given data

weekly = $325

commission= 7.5%

if she sold $5,800 worth of merchandise

Her earnings will be

Week earning= base salary+ 7.5% of sales

Week earning= 325+ 7.5/100*5800

Week earning= 325+ 0.075*5800

Week earning= 325+ 435

Week earning= $760

ANSWER:

tan(30⁰)=√3/3

cos(30⁰)=√3/2

sin(x) /√3/2 =√3/3

3·sin(x) /√3/2 =3·√3/3

2√3 sin (x) =√3

2√3 sin (x) / 2√3 = √3 / 2√3

sin (x)= 1/2

Answer:

6 ft < L₃ < 30 ft

Step-by-step explanation:

To obtain the answer to the question given above, we must bear in mind that:

The sum of the length of two sides of any triangle is always greater than the 3rd length i.e

L₁ + L₂ > L₃

With the above information in mind, we can obtain the answer to the question given above as follow:

Length 1 (L₁) = 12 feet

Length 2 (L₂) = 18 feet

Length 3 (L₃) =..?

Case 1:

L₁ + L₂ > L₃

12 + 18 > L₃

30 > L₃

L₃ < 30 feet

Case 2:

L₁ + L₃ > L₂

12 + L₃ > 18

Collect like terms

L₃ > 18 – 12

L₃ > 6 feet

Thus,

6 feet < L₃

Combining case 1 and 2,we obtained:

6 ft < L₃ < 30 ft

Therefore, the possible Lenght of the 3rd side is : 6 ft < L₃ < 30 ft

Answer:

[tex]x = 13[/tex]

Step-by-step explanation:

Given

See attachment

Required

Find x

From the attachment, we have:

[tex]BC = x + 4[/tex]

[tex]BD = 2x - 7[/tex]

[tex]GE = 51[/tex]

[tex]GF = 57[/tex]

Because both triangles are similar, we use the following equivalent ratios:

[tex]BC : BD = GE : GF[/tex]

Substitute values for each parameter

[tex]x + 4 : 2x- 7 = 51 : 57[/tex]

Convert to fractions

[tex]\frac{x + 4}{2x- 7} = \frac{51 }{ 57}[/tex]

Simplify the right-hand side

[tex]\frac{x + 4}{2x- 7} = \frac{17}{19}[/tex]

Cross Multiply

[tex]19(x + 4) = 17(2x - 7)[/tex]

[tex]19x + 76 = 34x - 119[/tex]

Collect Like Terms

[tex]19x - 34x = -76 - 119[/tex]

[tex]-15x = -195[/tex]

Solve for x

[tex]x = \frac{-195}{-15}[/tex]

[tex]x = 13[/tex]

Answer: x=13

Step-by-step explanation:

:(x+4) 57 = (2x-7) 5157x + 228 = 102x - 357357+228 = 102x - 57x585 = 45x13 =

Step-by-step explanation:

Answer:

141036.25

Step-by-step explanation:

Answer:

Answer is c. I, II and II

Step-by-step explanation:

Solution:

Answer is c. I, II and II

It will be increase by 10 points and it will be 10 points higher than the median for the noncurved data. and it will be halfway between Q1 and Q3 for the curved data.

Median for noncurved data = Q2 = 80

Median for curved data = 90

It will increase by 10 points = 90  

It will be 10 points higher than the noncurved data = 90-80 = 10 points

if the set contains 20 values then, noncurved data will be:

60 _ _ _ _ 70 _ _ _ _ 80 _ _ _ _ 87 _ _ _ _ 95

Curved data will be: (all grades increased by 10 points)

70 _ _ _ _ 80 _ _ _ _ 90 _ _ _ _ 97 _ _ _ _ 105

Here, we can see median = Q2 = 90, exactly, halfway between Q1 =80 and Q3 = 97

Hence, C is the right answer

====================================================

Explanation:

The weird looking E symbol is the greek uppercase letter sigma. It refers to a sum.

It tells us to add up terms in the form (-1)^n*(3n+2) where n is an integer ranging from n = 1 to n = 4.

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

If n = 1, then we have

(-1)^n*(3n+2) = (-1)^1*(3*1+2) = -5

Let A = -5 as we'll use it later.

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

If n = 2, then

(-1)^n*(3n+2) = (-1)^2*(3*2+2) = 8

Let B = 8 since we'll use this later as well

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

If n = 3, then

(-1)^n*(3n+2) = (-1)^3*(3*3+2) = -11

Let C = -11

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

If n = 4, then

(-1)^n*(3n+2) = (-1)^4*(3*4+2) = 14

Let D = 14.

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

We'll add up the values of A,B,C,D to get the final answer

A+B+C+D = -5+8+(-11)+14 = 6

This means that

[tex]\displaystyle \sum_{n=1}^{4}(-1)^n(3n+2) = 6[/tex]

Answer:

d. 80

Step-by-step explanation:

Similarity ratio of ABCD to EFGH = 4:3.

This implies that the ratio of AD to EH = 4:3

If EH = 60, then:

AD:60 = 4:3

AD/60 = 4/3

Multiply both sides by 60

AD = ⁴/3 × 60

AD = 80

Answer:

We conclude that the length of LM if L(3,4) and M(1,-2) will be:

[tex]d = 6.3[/tex]

Hence, option D is correct.

Step-by-step explanation:

Given

Determining the length of LM

The length of the distance between (x₁, y₁)  and (x₂, y₂)  can be determined using the formula

[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)

   [tex]=\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}[/tex]

   [tex]=\sqrt{2^2+6^2}[/tex]

   [tex]=\sqrt{4+36}[/tex]

   [tex]=\sqrt{40}[/tex]

   [tex]=\sqrt{4\times 10}[/tex]

   [tex]=\sqrt{2^2\times \:10}[/tex]

   [tex]=2\sqrt{10}[/tex]

   [tex]=6.3[/tex]

Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:

[tex]d = 6.3[/tex]

Hence, option D is correct.

The net of the solid is a plane shape, and The net of the solid is made from 6 faces

From the question, we understand that:

So, the number of faces is:

Face = Triangle + Pentagon

This gives

Face = 5 + 1

Face = 6

Hence, the net of the solid is made from 6 faces

Answer:

d ≈ 10.5

Step-by-step explanation:

The formula for the diagonal of a retangular prism (cuboid) is

[tex]d=\sqrt{l^2+w^2+h^2}[/tex]

1.) Plug in all the values for l, w, and h

[tex]d=\sqrt{5^2+6^2+7^2}[/tex]

2.) simplify by squaring the terms inside the square root

5 * 5 = 25

6 * 6 = 36

7 * 7 = 49

Answer: No, it is not commutative. If used a square as an example, centered at (1,1). If a dilation is performed on the square of a scale factor of 3, and the square is translated 5 units downward, then the result would be different than if I switched the order, doing the translation downward first and then performing the dilation centered at (1,1).
