Answer: D because the two longer sides are 7 unites longer, meaning you need to add 14 (7x2) to the final product

Answer:

Option D [tex]4x+14[/tex]

Step-by-step explanation:

Given: The longer sides are 7 units longer than the shorter sides. The shorter side is x.

To find: Write an expression below that represents the perimeter.

Solution: It is given that the shorter side is x.

The longer side is 7 units longer than the shorter side. So, the longer side is [tex]x+7[/tex]

We know that the perimeter of the rectangle is [tex]2(\text{length}+\text{breadth})[/tex]

So, the expression for the perimeter

[tex]=2(x+x+7)[/tex]

[tex]=2(2x+7)[/tex]

[tex]=4x+14[/tex]

Hence, the expression for perimeter is [tex]4x+14[/tex].

So, option D is correct.

Hello!

your answer is: 4

2 cubed is also written as: 2³

2 squared is also written as: 2²

so the re-written equation is: 2³ - 2²

To solve, simplify by doing the exponents.

2³ = 8

2² = 4

8 - 4 = 4

I hope this helps, and have a nice day!

Answer:

yes they're congruent.

The given information does not provide specific triangles or measurements needed to determine congruency, making it impossible to answer the question.

The question asks about determining whether pairs of triangles are congruent and identifying the congruence criteria (SSS, SAS, ASA).

Unfortunately, the provided information does not include any pairs of triangles or any specific measurements needed to determine congruency.

Therefore, it is not possible to answer the question based on the given information.

The correct answer is (B) Only (-3, 3).

To determine which ordered pair is a solution of the equation, you need to substitute the values of \( x \) and \( y \) into the equation and see if it holds true. Let's check:

For option A: (-4, 4)
Substituting into the equation: \( -3(-4) - 4 - 6 = 12 - 4 - 6 = 2 \) which is not equal to 0, so it's not a solution.

For option B: (-3, 3)
Substituting into the equation: \( -3(-3) - 3 - 6 = 9 - 3 - 6 = 0 \) which is equal to 0, so it is a solution.

Thus, the correct answer is (B) Only (-3, 3).

Complete question :

Answer:

The slope of the line is 3

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have a line that passes through the origin,

so

The graph shows a proportional relation ship

[tex]k=y/x[/tex]

For (1,3) ------> [tex]k=3/1=3[/tex]

For (2,6) ------> [tex]k=6/2=3[/tex]

For (3,9) ------> [tex]k=9/3=3[/tex]

The equation is

[tex]y=3x[/tex]

The slope of the line is 3

Answer:

The slope of the line is 3.

Step-by-step explanation:

In the graph x-axis shows Pyramid Volume in cubic units and the y-axis shows Prism Volume in cubic units.

The line starts at (0, 0) and passes through (1, 3), (2, 6) and (3, 9).

If a line passes through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the slope of the line is

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Consider any two points of the line: (0, 0) and (1, 3). So, the slope of the given line is

[tex]m=\frac{3-0}{1-0}[/tex]

[tex]m=3[/tex]

Therefore, the slope of the line is 3.

Answer:

The value of x = 0.5, y = 0.8 and z = 0.9

Step-by-step explanation:

From the given figure. Let's form the equations

50z + 13 + 45x + [tex]\frac{19}{2}[/tex] = 90°

45x + 50z + 13 + 9.5 = 90

45x + 50z + 22.5 = 90

45x + 50z = 90 - 22.5

45x + 50z = 67.5  --------------------------(1)

[tex]\frac{225y}{2} = 90[/tex]° Because it is a right angle.

225y = 180

y = [tex]\frac{180}{225}[/tex]

y = 0.8   --------------------(2)

44x + 125y + 80z -14 = 180° because they are supplementary angles add upto 180 degrees.

44x + 125y + 80z = 180 + 14

44x +125y + 80z = 194  ------------(3)

Now plug in y = 0.8 in the above equation (3), we get

44x + 125 times 0.8 + 80z = 194

44x + 100 + 80z = 194

44x + 80z = 194 - 100

44x + 80z = 94 ---------------------(4)

Now let's solve the equation (1) and (4) using elimination method.

x = 0.5

Now plug in x = 0.5 in the equation (4) and find the value of z

44(0.5) + 80z = 94

22 + 80z = 94

80z = 94 - 22

80z = 72

z = [tex]\frac{72}{80}[/tex]

z = 0.9

Therefore, the value of x = 0.5, y = 0.8 and z = 0.9

The natural numbers for which x/8 is a proper fraction and x/4 is an improper fraction are 4, 5, 6, and 7.

Firstly, let's understand what proper and improper fractions are. A proper fraction is a fraction whose numerator is less than the denominator, and an improper fraction is a fraction whose numerator is equal to or greater than the denominator.

Given that x/8 is a proper fraction and x/4 is an improper fraction, we are looking for a number that is less than 8 (for the proper fraction) and equal to or greater than 4 (for the improper fraction). These restrictions on x mean that x must be in the range 4 ≤ x < 8.

When we consider that x should be a natural number, the only numbers that meet this criterion are 4, 5, 6, and 7. Hence, these are the natural values of x for which x/8 is a proper fraction and x/4 is an improper fraction.

https://brainly.com/question/33440318

#SPJ2

Final answer:

The values of x that meet both conditions are 5, 6, and 7.

Explanation:

In order to find natural values for x where x/8 is a proper fraction and x/4 is an improper fraction, we must first understand what proper and improper fractions are. A proper fraction is one where the numerator is less than the denominator, whereas an improper fraction has a numerator larger than or equal to the denominator. Given that x/8 must be a proper fraction, x must be less than 8. For x/4 to be an improper fraction, x must be greater than or equal to 4. Therefore, to satisfy both conditions simultaneously, x must fall within the range of 5, 6, or 7. This is because these are the only natural numbers less than 8 and greater than 4.

Answer:

7 groups, 3 boys and 8 girls

Step-by-step explanation:

Let total number of groups be [tex]x[/tex]

and total hikers in one group be [tex]y[/tex]

if number of girls and boys in every group is same, then

[tex]\frac{21}{x} + \frac{56}{x} = y[/tex]

[tex]\frac{21 + 56}{x} = y\\x*y = 77[/tex] ....(1)

from (1) [tex]x[/tex] will either be 11 or 7

for [tex]x = 11[/tex] the values won't be real.

For [tex]x = 7\\y = \frac{77}{7} \\y = 11[/tex]

so there will be 7 groups with 11 hikers in each groups and every group will have [tex]\frac{21}{7} = 3[/tex] boys and [tex]\frac{56}{7} = 8[/tex] girls

Solving the nested logarithmic equation log2 [log3 (log4 x)] = 0 requires repeatedly using the concept that y = logb(x) is equivalent to x = by, resulting in x = 64.

To answer your question, we'll need to understand that logarithmic expressions such as log2 [log3 (log4 x)]=0 can be solved by step-by-step process called exponentiation.

First, knowing that y = logb(x) is equivalent to x = by, we can re-write the equation log2 [log3 (log4 x)] = 0 as log3 (log4 x) = 20.

Then, using the concept that the logarithm of a number raised to an exponent is the product of the exponent and the logarithm of the number, move forward to solve log4 x = 31.

Finally, applying the same rule once more gives us x = 43 = 64.

1 cm is approximately 0.394 inches which is the fraction of an inch for 1 cm. This can be discovered by inverting the known relation (1 in = 2.54 cm) or by using dimensional analysis method.

The subject of your question concerns the conversion between the units of length, centimeters and inches. In measurement, it is known that 1 inch is equal to 2.54 centimeters. However, you asked what fraction of an inch is 1 centimeter. To find this, we need to invert the relation we know. Thus, 1 cm = 1/2.54 inches.

For a clearer understanding, 2.54 cm is exactly 1 inch (by definition). To find the fractional value of 1 cm in inches, we simply take the reciprocal (invert) of 2.54, because we are essentially asking the question, 'How many cm are there in 1 inch?'. This yields about 0.394, and thus 1 cm = 0.394 inch approximately.

Another method to understand this conversion is dimensional analysis. It tells us that we're able to convert one unit to another as long as the units are in the same dimension (in this case, length). So based on the relation 1 inch = 2.54 cm, we establish the conversion factor of 1/2.54 = 0.394 inch/cm. So 1 cm * 0.394 inch/cm gives us 0.394 inch.

Total: -141

Covert the ratios so they are all the same measurement type.

A. 5 feet = 5 x 12 = 60 inches.

The scale becomes 1:60

B. 1:30

C. 12 yards = 12 x 3 = 36 feet x 12 = 432 inches.

The scale is 12:432  = 1:36

D. 1 meter = 39.37 inches.

1 inch = 2.54 cm

39.37 x 2.54 = 99.99 inches

The scale converted to inches becomes 1 :100 inches.

The first number would be the size of the drawing, the second number is the size of the actual object

If you use all 4 scale factors for a real object that is 100 inches:

A would need 100/60 = 1.67 inches.

B would need 100/30 = 3.3 inches.

C would need 100/36 = 2.78 inches.

D would need 100/100 = 1 inch.

The larger scaled drawing would be B.

Answer:

Option B.

Step-by-step explanation:

We need to find which scale would produce the largest scale drawing of an object when compared to the actual object.

First of all cover all units in inches.

In option 1,

1 inch : 5 feet

We know that

1 feet = 12 inch → 5 feet = 60 inch

So the ratio in inches is 1:60. It means the scale factor is 60.

In option 2,

1 inch : 30 inches

So the ratio in inches is 1:30. It means the scale factor is 30.

In option 3,

1 foot : 12 yards

12 inches : 12 yards                     (1 feet = 12 inch)

1 inch : 1 yards

1 inch : 36 inch                     (1 yard = 36 inch)

So the ratio in inches is 1:36. It means the scale factor is 36.

In option 4,

1 centimeter : 1 meter

1 centimeter : 100 centimeter         (1 m = 100 cm)

1 inch : 100 inch

So the ratio in inches is 1:100. It means the scale factor is 100.

Option B has smallest scale factor, so it will produce the largest scale drawing of an object when compared to the actual object.

Therefore, the correct option is B.

Answer:$14.35

Step-by-step explanation:

The shop will charge $14.352 as markup price.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Cask’n’Cork wine shop that has a markup rate of 15%. A bottle of zinfandel wine costs $12.48 wholesale.

Assume that the shop charges $x. Then, we can write -

x = 12.48 + 15% of 12.48

x = 12.48 + (15/100) x 12.48

x = 12.48 + (3/20) x 12.48

x = 12.48 + 1.872

x = 14.352

Therefore, the shop will charge $14.352 as markup price.
