Answer:

3)  x = 15; 95 and 85      4)  x = 12; 98 for both angles

Step-by-step explanation:

2x + 65 + 3x + 40 = 180       Set the equations equal to 180

5x + 105 = 180                      Combine like terms

     - 105  - 105                      Subtract 105 from both sides

5x = 75                                  Divide both sides by 5

x = 15

Plug 15 into both equations

2(15) + 65 = 95

3(15) + 40 = 85

4)  5x + 38 = 9x - 10             Set the equations equal to each other

  - 5x          - 5x                    Subtract 5x from both sides

 38 = 4x - 10

+ 10       + 10                         Add 10 to both sides

48 = 4x                                  Divide both sides by 4

12 = x

Plug 12 into both equations

5(12) + 38 = 98

9(12) - 10 = 98

1 million is 1*10^6

300 thousand is 3*10^5

Since 300,000 is one power of ten below 1 million, it's either A or B.

The correct choice is A, however, because of 1 million being 10^6. We choose the biggest value we get.

The options that  can be angle measures of a triangle is

2. Set: 25°, 130°, 25°

How to find measure of triangle

To determine whether a set of three angle measures can be the angle measures of a triangle, you can use the sum of internal angles of a triangle which is 180 degrees

Let's analyze each set of three angle measures:

1. Set: 41°, 112°, 52°

41 + 112 + 52 = 205

This cannot be a triangle

2. Set: 25°, 130°, 25°

25 + 130 + 25 = 180

This can be a triangle

3. Set: 30°, 40°, 90°

30 + 40 + 90 = 160

This cannot be a triangle

4. Set: 132°, 141°, 31°

132 + 141 + 31 = 304

This cannot be a triangle

It costs $ 30240 to stain floor of the entire room

Solution:

Given that,

Sgt. Merritt has bought a house now that his tour of duty is up

He wants to stain the wood floors of the living room, which measure 18 x 14

Therefore,

length = 18 yards

Width = 14 yards

[tex]Area = length \times width\\\\Area = 18 \times 14\\\\Area = 252[/tex]

Thus area of wood floors is 252 square yards

The stain costs $120 per square yard

[tex]Cost = 252 \times 120\\\\Cost = 30240[/tex]

Thus it costs $ 30240 to stain floor of the entire room

To stain Sgt. Merritt's living room floors, which measure 18x14 feet, first calculate the area in square feet, convert to square yards, and then multiply by the cost per square yard. The total cost will be $3,360.

To determine the cost to stain the wood floors in the living room, first we need to calculate the total area in square yards since the stain is sold by square yard. The room measures 18 feet by 14 feet.

Step 1: Calculate Square Footage

Multiply the length and width in feet to get the square footage:

18 feet × 14 feet = 252 square feet

Step 2: Convert Square Feet to Square Yards

There are 9 square feet in 1 square yard. Therefore, we divide the total square footage by 9 to convert to square yards:

252 square feet / 9 square feet per square yard = 28 square yards

Step 3: Calculate the Cost

The cost to stain one square yard is $120. So, we multiply the total square yards by $120 to get the total cost:

28 square yards × $120 per square yard = $3,360

Therefore, the cost to stain the entire living room floor will be $3,360.

Step-by-step explanation:

To find out how much weight the black bear lost during hibernation, subtract the weight after hibernation from the weight before hibernation: 265 - 260 = 5 pounds.

To find out how much weight the black bear lost during hibernation, we can use the information that black bears lose 1/5 of their body weight during hibernation. We know that the black bear weighed 265 pounds before hibernation and weighs 260 pounds after hibernation. To calculate the weight loss, we subtract the weight after hibernation from the weight before hibernation: 265 - 260 = 5 pounds. Therefore, the black bear lost 5 pounds while hibernating.

Step-by-step explanation:

The 5 in 458,039 is 100 times greater than the 5 in 271,145 because it represents 50,000 while the 5 in 271,145 represents 500. This can be determined by understanding place values, as each digit's value depends on its position in the number.

The 5 in 458,039 is in the ten thousands place, meaning it represents 50,000. The 5 in 271,145 is in the hundreds place, meaning it represents 500. To understand how many times greater one is than the other, we would divide 50,000 by 500. The result is 100, therefore, the 5 in 458,039 is 100 times greater than the 5 in 271,145. So, the answer is B. 100.

The wavelength of an electromagnetic wave with a frequency of 135,000 Hz is approximately 2,222 meters. This can be calculated using the equation λ = c / f, with c being the speed of light and f the frequency of the wave.

The wavelength of an electromagnetic wave can be calculated from the frequency when we understand their relationship through the wave's speed. In the case of an electromagnetic wave, this speed is the speed of light (denoted by c), which is approximately 3.00 x 108 m/s. This relationship is expressed by the equation c = fλ, where f is the frequency and λ is the wavelength.

To calculate the wavelength (λ) from the frequency (f), we rearrange the equation to λ = c / f. Substituting 3.00 x 108 m/s for c and 135,000 Hz for f, gives λ = 3.00 x 108 m/s / 135,000 Hz. After performing the calculation, we find the wavelength to be approximately 2,222 meters.

The wavelength of an electromagnetic wave with a frequency of 135,000 Hz is approximately 2,222 meters, based on the relationship provided by the equation c = fλ.

The wavelength of an electromagnetic wave is directly related to its frequency by the equation c = fλ, where 'c' is the speed of light in vacuum, 'f' is the frequency and 'λ' is the wavelength. In this equation, the speed of light 'c' is typically 3.00 × 108 m/s. Therefore, if we want to figure out the wavelength of an electromagnetic wave with a frequency of 135,000 Hz, we can rearrange the equation to solve for the wavelength: λ = c/f. Substituting the given values, we have λ = (3.00 × 108 m/s)/(135,000 s-1), which simplifies to λ = 2,222 m.

In the image, the length of the segment will be 120 units.

Step-by-step explanation:

Whatever may be transformation, either rotation, reflection or translation, the length the line segment will not change.

Here one segment with 120 units and other segment with 240 units is rotated 90 degrees about the origin and then it is translated 50 units up, we will get the image of the segment with the same size.

In the image, the length of the segment will be 120 units.

P = perimeter

L = length

W = width

Formula for the perimeter of a rectangle = L + L + W + W  or  P = 2L + 2W

You know:

P = 110ft

L = W + 5  [length is 5ft greater than the width]

So plug this into the formula:

P = 2L + 2W             Substitute/plug in (W + 5) for L

110 = 2(W + 5) + 2W           Distribute/multiply 2 into (W + 5)

110 = (2)W + (2)5 + 2W

110 = 2W + 10 + 2W       Combine like terms (2W + 2W)

110 = 4W + 10       Subtract 10 on both sides

110 - 10 = 4W + 10 - 10

100 = 4W     Divide 4 on both sides to get "W" by itself

[tex]\frac{100}{4}=\frac{4W}{4}[/tex]

25 = W        Now that you know the width, plug it into the equation for length

L = W + 5       Plug in 25 for W

L = 25 + 5

L = 30

L = 30 ft

W = 25 ft

PROOF

P = 2L + 2W

110 = 2(30) + 2(25)

110 = 60 + 50

110 = 110

The solution to the system of equations is x = -2 and y = 4

How to solve the equation

To solve this system of equations using Cramer's rule, we need to first express the equations in standard form: Ax + By = C

According to the problem, we have the equations

4x + 3y - 4 = 0

6x = 8 - 5y.

This is the same as

4x + 3y = 4

6x + 5y = 8

The determinants required for Cramer's rule:

Coefficient matrix (D)

[tex]\[D = \begin{vmatrix} 4 & 3 \\ 6 & 5 \end{vmatrix} = (4 \times 5) - (3 \times 6) = 20 - 18 = 2\][/tex]

For Dₓ

[tex]\[D_x = \begin{vmatrix} 4 & 3 \\ 8 & 5 \end{vmatrix} = (4 \times 5) - (3 \times 8) = 20 - 24 = -4\][/tex]
