Answer:

76 m

Step-by-step explanation:

The area of a rectangle = length × width.

If we know that the area is 4864m² and the width is 64m, we can substitute this into the formula:

4864 = length × 64

To find the length, all we have to do is divide the area by 64: length = 4864 ÷ 64 = 76 m

Answer:

3(x-7) – x=2x-21 ( the equation)

--> infinitely many solutions

Step-by-step explanation:

The solution of the equation is infinitely many solutions, the correct option is C.

In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We are given that;

Equation 3(x-7) – x=2x-21

Now,

To solve the equation, we need to simplify both sides and isolate x. We can do this by following these steps:

3(x-7) – x = 2x - 21 Expand the parentheses by multiplying 3 with x and -7:

3x - 21 - x = 2x - 21 Combine like terms on the left side by subtracting x from 3x:

2x - 21 = 2x - 21 Subtract 2x from both sides to eliminate x:

-21 = -21 This equation is always true, regardless of the value of x. This means that the equation has infinitely many solutions. Any value of x will satisfy the equation

Therefore, the answer of the given equation will be  infinitely many solutions

The ratio of y:x should be constant for any value of x and y.

If go over every table, you'll find that this is true for the third one and that the ratio is r=50

The table showing the proportional relationship between x and y is the third one.

Two sequences of numbers, often experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, which is called the coefficient of proportionality or proportionality constant.

Given are four tables, giving values of x and y, we need to identify the table giving the relation between x and y which is proportional.

Table 1)

x = 1, 2, 3, 6

y = 1.5, 3, 6, 9

y/x = 1.5, 1.5, 2, 1.5 [not proportional]

Table 2)

x = 2, 4, 5, 6

y = 6, 12, 18, 21

y/x = 3, 3, 3.6, 3.5 [not proportional]

Table 3)

x = 1, 3, 4, 5

y = 50, 150, 200, 250

y/x = 50, 50, 50, 50 [proportional]

Hence, the table showing the proportional relationship between x and y is the third one.

Answer:

60

Step-by-step explanation:

m(ADB) + m(BDC) = 90°

(3x+9) + (2x -4) = 90°

5x + 5 = 90°

5x = 85

5x/5 = 85/5

x = 17

m(ADB) = 3x + 9

3.17 + 9 = 51 + 9 = 60

Hope this helps ^-^

Answer: 60°

Step-by-step explanation:

Looking at the figure, we know that the angles add up to 90°. We add both equations and solve for x.

3x+9+2x-4=90          [combine like terms]

5x+5=90                    [subtract both sides by 5]

5x=85                        [divide both sides by 5]

x=17

Now that we know x, we can plug it into ADB to find the angle.

3(17)+9                      [multiply]

51+9                          [add]

60

Now, we know that ADB is 60°.

Answer:

unit rate = 0.9 miles per hour

Step-by-step explanation:

Rate per hour of walking is calculate by = distance moved in miles/ time taken in miles

_________________________

given

distance = 3/5 of a mile = 3/5 miles

time = 40 minutes

we have to find time in hours

60 minutes = 1 hour

40 minutes = 1/60 *40 hours = 2/3 hours

thus

unit rate = (3/5 miles)/ (2/3 hours ) = (3*3)miles/(5*2) hour = 9/10 miles per hour

The set of data 6, 2, 2, 2  will have the least dispersion from its mean.

From four sets of data, we take the mean of 6,2,2,2

[tex]\rm mean =\dfrac{ Sum \ of\ data}{Number \ of\ data}[/tex]

So the mean will be

[tex]\rm mean =\dfrac{ 6+2+2+2}{4}=\dfrac{12}{4} =3[/tex]

So the mean of the data (6,2,2,2) is 3 which has the least dispersion from its every data as compared to the other data

Answer:

(True or False) The inequality |x + 1| < 0 has no solution.

Solution

The absolute value of a real expression is either positive or equal to zero. Therefore there is no value of x that makes |x + 1| negative and therefore |x + 1| < 0 is never true and the statement "The inequality |x + 1| < 0 has no solution" is TRUE.

Number  = 15.

Step-by-step explanation:

Given : If you multiply a number by 3 and then subtract 5, you will get 40.

To find : what is the number.

Solution : We have given if you multiply a number by 3 and then subtract 5, you will get 40.

According to question :

Let the number =  x

Multiply is with 3 = 3x

Subtract 5 from it we get 40 .

3x -5 = 40

On adding both sides by 5

3x = 45 .

On dividing both sides by 3

x =  15.

Therefore, Number  = 15.
