[tex]v = u + 5t\\\\5t=v-u\\\\t=\dfrac{v-u}{5}[/tex]

To make t the subject of the formula v = u + 5t, subtract u from both sides and divide by 5.

To make t the subject of the formula v = u + 5t, we need to isolate t on one side of the equation.

First, subtract u from both sides of the equation: v - u = 5t.

Then, divide both sides of the equation by 5: (v - u)/5 = t.

THE SQUARE PERIMETER X IS TWO THIRDS OF THE SQUARE PERIMETER Y. THE PERIMETER OF THE SQUARE Y IS TWO THIRDS OF THE PERIMETER OF THE SQUARE Z. THE AREA OF THE SQUARE X IS 16 CM2 WHAT IS THE AREA OF THE SQUARE Z?

Let

Px--------> the perimeter of square x

Py--------> the perimeter of square y

Pz--------> the perimeter of square z

Ax--------> the area of square x

Az--------> the area of square z

Step 1

Find the length side of the square x

we know that

[tex]Px=\frac{2}{3} Py[/tex] -------> equation A

[tex]Py=\frac{2}{3} Pz[/tex] -------> equation B

[tex]Ax=16\ cm^{2}[/tex]

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

so

[tex]x^{2}=16[/tex]

[tex]x=4\ cm[/tex]

Step 2

Find the perimeter of square x

[tex]Px=4x[/tex]

substitute the value of x in the formula

[tex]Px=4*4=16\ cm[/tex]

Step 3

Find the perimeter of square y

use the equation A

[tex]Px=\frac{2}{3} Py[/tex]

solve for Py

[tex]Py=\frac{3}{2} Px[/tex]

substitute the value of Px

[tex]Py=\frac{3}{2}16=24\ cm[/tex]

Step 4

Find the perimeter of square z

use the equation B

[tex]Py=\frac{2}{3} Pz[/tex]

solve for Pz

[tex]Pz=\frac{3}{2} Py[/tex]

substitute the value of Py

[tex]Pz=\frac{3}{2} 24=36\ cm[/tex]

Step 5

Find the area of square z

we know that

the area of the square z is equal to

[tex]Az=z^{2}[/tex]

Find the length side of square z

[tex]Pz=4z[/tex]

[tex]Pz=36\ cm[/tex]

so

[tex]4z=36[/tex]

[tex]z=9\ cm[/tex]

substitute the value of z in the area's formula

[tex]Az=9^{2}=81\ cm^{2}[/tex]

therefore

the answer is

the area of the square z is [tex]81\ cm^{2}[/tex]

Answer:

86

Step-by-step explanation:

The pattern follows this rule:

Every time, the difference between current term and the succeeding term is 0.5 more than that of the current term and preceding term.

The difference between the current term and the preceding term is:

89.5 - 92.5 = 3

Hence, the next term of the sequence should be 3.5 less than the current term.

Hence, the next term is 89.5 - 3.5 = 86.

Step-by-step explanation:

Sales tax paid by Donte = [tex]\frac{5.6}{100} (5)[/tex]

= 0.28

Sales tax paid by Trista = [tex]\frac{7}{100} (5)[/tex]

= 0.35

The extra tax paid by Trista = 0.35 - 0.28 = 0.07.

Hence, Trista paid $0.07 more than Donte.

To calculate the total amount Aleta spent, including the tip, multiply the bill ($36) by the tip percentage (15%) to get the tip amount ($5.40) and add it to the bill to get the total cost ($41.40).

The question asks us to calculate the total amount Aleta spent on dinner including a 15% tip. To find the tip amount, we multiply the bill by the tip percentage in decimal form. The bill is $36, so we calculate 15% of $36 as follows:

0.15 × $36 = $5.40

The total cost of the meal including the tip is $36 (the original bill) + $5.40 (the tip) = $41.40.

5 . x ÷ 7 = 10 or less

5 . 14 = 70 ÷ 7 = 10

The unknown number, when multiplied by five and divided by seven, has to result in a value of 10 or less. To find this number, we solve the inequality 5x / 7 <= 10 and find that x must be less than or equal to 14.

The question is asking for a number that, when multiplied by five and then divided by seven, yields a result of 10 or less. Let's denote the unknown number as x. We can put this into a mathematical inequality:

5x / 7 <= 10

To solve for x, we first multiply both sides by 7 to cancel the denominator on the left side:

5x <= 70

Then, we divide both sides by 5 to isolate x:

x <= 14

Therefore, the number must be less than or equal to 14.

The riddle compares a lame elephant to the act of adding 19 and 4, where the answer lies in the wordplay of 'one-legged' (1+9+4) and 'too-free' (sounding like 23).

The question "Why is a lame elephant like adding 19 and 4?" appears to be a playful riddle rather than a straightforward math problem.

The answer to this riddle plays on the similarity in sound between the words 'lame' and the number '1' when saying 'one-legged' or '1-legged', as well as the sum of the numbers 19 and 4 being 23, which can sound like 'two' and 'three' or 'too-free' when spoken quickly.

To conclude, a lame elephant is like adding 19 and 4 because it is 'one legged' or could be jokingly considered 'too-free' to walk as it would if it weren't lame.

Answer:  The required length and breadth of the rug are 46 yards and 189 yards respectively.

Step-by-step explanation:  Given that a rectangular rug has a perimeter of 470 yards. The width of the rug is 5 yards more than four times the length.

We are to find the length and width of the rug.

Let l represents the length of the rug. Then, the width of the rug will be

[tex]w=4l+5.[/tex]

According to the given information, we have

[tex]470=2l+2w\\\\\Rightarrow 470=2l+2(4l+5)\\\\\Rightarrow 470=2l+8l+10\\\\\Rightarrow 10l=460\\\\\Rightarrow l=\dfrac{460}{10}\\\\\Rightarrow l=46.[/tex]

So, the width is given by

[tex]w=4\times46+5=184+5=189.[/tex]

Thus, the required length and breadth of the rug are 46 yards and 189 yards respectively.

[tex]4+\dfrac{3}{5}\left(15+2x\right)=25\\\\\dfrac{3}{5}\left(15+2x\right)=21\\\\15+2x=35\\\\2x=20\\\\x=10[/tex]

To determine the size of the home video collection one can save, subtract the used space (122 GB) from the total hard drive capacity (160 GB). The remaining space is 38 GB, which is the maximum size for the home videos that can be saved. The inequality representing the available space in terms of 'a' is: a ≤ 38 GB.

The subject of this question is a practical application of mathematics related to computer storage space.

If the computer's hard drive has a total capacity of 160 GB and you have already used 122 GB, we can determine the remaining available space with a simple subtraction: 160 GB - 122 GB = 38 GB.

So, the size of the home video collection that you can save cannot exceed 38 GB.

To represent this as an inequality where u is the amount used, and a is the amount available, we can write:

u + a ≤ 160 GB

Since you've used 122 GB already, the inequality in terms of a alone is:

a ≤ 160 GB - 122 GB

a ≤ 38 GB

This inequality states that the amount of additional data (home videos) you can save, denoted as a, should be less than or equal to 38 GB, which is the available space remaining on your hard drive.

Final answer:

To determine the available space on your hard drive, subtract the amount used from the total capacity. The possible sizes of the home video collection you can save range from 0GB to a maximum of 38GB. The inequality a ≤ 38GB represents the amount of space available.

Explanation:

To determine the amount of space available, you subtract the amount of space used from the total capacity. In this case, the total capacity is 160GB and the amount used is 122GB, so the amount of space available is 160GB - 122GB = 38GB.

Therefore, the possible sizes of the home video collection you can save range from 0GB (if you don't save any videos) up to a maximum of 38GB (if you save videos that take up the entire available space).

The inequality that represents this is: a ≤ 38GB, where 'a' represents the amount of space available.

Vanessa originally had $685. After spending $273 and donating $119, she now has $293 remaining.

To find out how much money Vanessa has left after spending and donating some of her money, we need to perform two subtraction operations. First, subtract the amount she spent from her original amount, then subtract what she donated.

Vanessa had $685 originally. She spent $273 on purchases, so let's subtract this amount:

After spending, Vanessa has $412 left. Now, let's subtract the amount she donated:

So, after donating, Vanessa has $293 left.

Final answer:

Vanessa initially has $685. After spending $273 and donating $119, she has $293 left.

Explanation:

The question involves solving a basic arithmetic problem. Vanessa initially has $685. She spends $273 and then donates $119. To find out how much money Vanessa has left, we need to subtract the total amount spent and donated from her initial amount.

Step-by-Step Calculation:

Therefore, after spending and donating the specified amounts, Vanessa has $293 left.
