Answer:

6.86 kg

Step-by-step explanation:

Here ,apparently the weight and number of sheets are proportional.

Let m be the weight of 700 sheets.

[tex]\text{} \begin{matrix}500\ \text{sheets} \text{} \longrightarrow 4.9\ \text{kg} \\ 700\ \text{sheets} \text{} \longrightarrow m\ \text{kg} \end{matrix}[/tex]

coefficient of proportionality :

[tex]\text{} \text{The coefficient of proportionality is equal to :} \ \frac{700}{500} =\frac{7}{5}[/tex]

Then

[tex]\frac{m}{4.9} = \frac{7}{5}[/tex]

Then

[tex]m = \frac{7}{5} \times 4.9 =6.86 \ \text{kg}[/tex]

Kenneth will have to run 2.25 minutes at the same speed to win the bet.

Speed is the rate of movement of an object along a path in time.

=> [tex]Speed =\frac{Distance}{Time}[/tex]

Now,

Given:

To find: Number of minutes to maintain the speed to win the bet.

Finding:

According to the information given in the question,

The speed in minutes = [tex]\frac{400}{54}(60)[/tex] = 444.44 meter/min

Since Kenneth is determined to run at this speed for 1 km, he will have to maintain it for:

=> [tex]\frac{1000}{444.44}[/tex] = 2.25 minutes (As [tex]Speed =\frac{Distance}{Time}[/tex], => [tex]Time=\frac{Distance}{Speed}[/tex])

Hence, Kenneth will have to run 2.25 minutes at the same speed to win the bet.

The value of x of the first rectangular deck is 8.

For given question,

The perimeter of a one rectangular deck is 78 feet.

The length of the first rectangular deck is  represented as (2x + 3), and its width is represented as (3x-4).

Similarly, the perimeter of a second rectangular deck is 2 times the perimeter of the first deck with a length of (4x + 6) and a width of (6x -1).

We need to find the value of x of the first rectangular deck.

Let P1 be the perimeter of the first rectangular deck.

⇒ P1 = 2 × (length + width)

⇒ 78 = 2 × [(2x + 3) + (3x - 4)]

⇒ 39 = (2x + 3x + 3 - 4)

⇒ 39 = 5x - 1

⇒ 40 = 5x

⇒ x = 40/5

⇒ x = 8

Therefore, the value of x of the first rectangular deck is 8.

Answer: 13 (simplified)

Step-by-step explanation: 9 + 4= 13, minus 9  equals 4

Answer: Question: x-9=4

Step-by-step explanation: X is 13

Answer:

x = 7

Step-by-step explanation:

Let's solve the problem,

→ 4x - 2x + x - 6 = 15

→ 3x - 6 = 15

→ 3x = 15 + 6

→ x = 21/3

→ [ x = 7 ]

Thus, the value of x is 7.

The value of "x" in the given figure and question is 20 units.

As per the question statement, We are given a figure in which we are supposed to find the value of x.

Before solving the question, if we observe the figure, we can conclude that this question will include the concepts of right angled triangle or specifically Pythagoras Theorem, which states that

[tex]Perpendicular^{2} + base^{2} = hypotenuse^{2}[/tex] where perpendicular, base and hypotenuse are the three sides of the right angled triangle.

In Triangle RTQ

using Pythagoras Theorem

[tex]RQ^{2} = TQ^{2} +TR^{2} \\RQ=x\\x^{2} = 16^{2} + TR^{2} \\TR^{2} = x^{2} -16^{2}[/tex]

Now considering triangle SRT

using Pythagoras Theorem

[tex]SR^{2} = RT^{2} + ST^{2} \\SR^{2} = (x^{2} -16^{2}) +9^{2}\\[/tex]

Now considering triangle RSQ

using Pythagoras Theorem

[tex]SQ^{2} = SR^{2} +RQ^{2} \\(9+16)^{2} = SR^{2} + RQ^{2} \\(9+16)^{2} = x^{2} -7^{2}+x^{2} \\ (9+16)^{2} =2x^{2} -7^{2} \\25^{2}+7^{2} = 2x^{2}[/tex]

[tex]2x^{2} =674[/tex]

[tex]x^{2} =337\\x=\sqrt{337} \\x=18.357[/tex]

Therefore x = 18.357 approx 20 units.

Step-by-step explanation:

Rational numbers are able to be denoted as a ratio. -2/7 is a ratio, so it is rational.

Over the weekend she walked a total distance of (4 + 5/8) miles

We know that on Saturday she walked a total of (3 + 7/10) miles (so we need to work with mixed numbers), and on Sunday she walked 0.25 of that distance.

Then the  distance that she walked on Sunday is:

D = 0.25*(3 + 7/10) miles

We can rewrite: 0.25 = 1/4

replacing that:

D = (1/4)*(3 + 7/10) mi = (3/4 + 7/40) mi

   = (30/40 + 7/40)mi = (37/40)mi

Then the total distance that she walked over the weekend is:

d = (3 + 7/10) mi +  (37/40)mi

  = (120/40 + 28/40) mi + (37/40) mi

  = (185/40)mi = (160/40 + 25/40) mi = (4  + 5/8) mi

Over the weekend she walked a total distance of (4 + 5/8) miles

The 1st 10 perfect squares are 1,4,9,16,25,36,49,64,81 and 100.

[tex]1^{2} =1\\2^{2} =4\\3^{2} =9\\4^{2} =16\\5^{2} =25\\6^{2} =36\\7^{2} =49\\8^{2} =64\\9^{2} =81\\10^{2} =100\\[/tex]

2. What does it mean for a number to a perfect square? provide an example.

By squaring a whole number or an integer, one can create perfect squares. Let's examine an illustration to get the idea behind perfect squares. We can use a set of four and a second set of six marbles for this. Let's set the marbles in order.

See the figure(1).

With four marbles, we can create a square with two rows and two marbles in each row. We can create a rectangle with 6 marbles that has 2 rows with 3 marbles in each row. It signifies that 4 = 2[tex]\times[/tex]2 and 6 = 3[tex]\times[/tex]2 mathematically. Let's concentrate just on the square-shaped numerals. Here, 4 = 2 × 2 = [tex]2^{2}[/tex].

Square A is smaller then Square B. Square B is smaller then Square C.

complete the equation each of the square shown.

3. Square A=Area=[tex]3^{2}[/tex]=9

4. Square B= Area=[tex]4.2^{2}[/tex]=17.64

5. Square C=Area= [tex]\frac{5}{2} =\frac{25}{4}[/tex]

Find the length of the side of the square for each area is given

The graph represent the equation [tex]y=x^{2}[/tex].

9.complete the table of values to find corresponding y-values.

if x =-1.4

Substituting in the equation [tex]y=x^{2}[/tex]

Then y=[tex]-1.4^{2}[/tex]

y=1.96.

Therefore, (x,y)=(-1.4,1.96)

if x =-1

Substituting in the equation [tex]y=x^{2}[/tex]

Then y=[tex]-1^{2}[/tex]

y=1.

Therefore, (x,y)=(-1,1)

if x =0

Substituting in the equation [tex]y=x^{2}[/tex]

Then y=[tex]0^{2}[/tex]

y=0.

Therefore, (x,y)=(0,0)

if x =[tex]\frac{2}{5}[/tex]

Substituting in the equation [tex]y=x^{2}[/tex]

Then y=[tex](\frac{2}{5}) ^{2}[/tex]

y=[tex]\frac{4}{25}[/tex].

Therefore, (x,y)=([tex]\frac{2}{5}[/tex],[tex]\frac{4}{25}[/tex])

if x =2

Substituting in the equation [tex]y=x^{2}[/tex]

Then y=[tex]2^{2}[/tex]

y=4.

Therefore, (x,y)=(2,4)

10. why the graph of equation  [tex]y=x^{2}[/tex] is above x-axis.

Because the [tex]y=x^{2}\\[/tex] the x values are always positive because x as a square. So, the equation is always on x- axis or above x-axis.

x = 12.

Perpendicular lines are lines that intersect at a 90-degree angle. So, for example, line ST is perpendicular to line CD. So line ST is perpendicular to line CD.

Perpendicular lines always intersect each other, however, all intersecting lines are not always perpendicular to each other. The two main properties of perpendicular lines are: Perpendicular lines always meet or intersect each other. The angle between any two perpendicular lines is always equal to 90.

Given that

line m and n are perpendiculars

then angle ∠a = ∠b

then

5x + 20 = 7x -4

7x -5x = 20 + 4

2x = 24
