A square has a side length of 15 cm. Which of the following is closest to the
length of a diagonal of the square?

A. 15 cm
B. 18 cm
C. 21 cm
D. 24 cm

PLEASE HELP PLEASE!!!!

Answers

Answer 1
21cm cause a^2 + b^2 = c^2
so 15^2 + 15^2 = 450 and the square root of 450 rounds to 21
Answer 2

The length of a diagonal of the square is 21cm.

What is the diagonal of the square?

A square can have two diagonals. Each of the diagonal can be formed by joining the diagonally opposite vertices of a square.

A square has a side length of 15 cm.

The following is closest to the length of a diagonal of the square is;

[tex]\rm d^2 =15^+15^2\\\\d^2=225+225\\\\d^2=450\\\\d=21[/tex]

Hence, the length of a diagonal of the square is 21cm.

A company makes muesli which contains nuts and sultanas.

They counted the number of nuts in 50 individual serving packets.

They drew a table.

To Find :

complete the table

calculate and estimate for the mean

The estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.

a) To complete the table, we need to find the values of "fx" (frequency multiplied by the midpoint) for each class interval. Here's the updated table:

Number of Nuts Number of Packets Midpoint (x) fx

4-6 5 5 5 * 3 = 15

7-9 8 8 8 * 9 = 72

10 - 12 11 11 11 * 12 = 132

13 - 15 14 14 14 * 17 = 238

16 - 18 17 17 17 * 9 = 153

Total 50  610

b) To calculate an estimate for the mean, we use the formula:

Mean = Sum of (fx) / Total Number of Packets

Mean = 610 / 50

Mean ≈ 12.2

Therefore, the estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.

A shelf is 36 inches long. How many DVD’s can I place on it if each one is 5/8 inches thick?

Answers

we can find this by diving 36 by 5/8
We will use the keep, change, flip rule
So instead of 36 / 5/8
We will calculate as
36 * 8/5
We will first multiply 36 * 8 = 288
Now we have 288/8 = 36
This means 36 DVDs will fit on the shelf

You can place approximately 57 DVDs on the shelf if each DVD is 5/8 inches thick. To determine the number of DVDs that can fit on a shelf, we need to divide the length of the shelf by the thickness of each DVD.

The shelf is 36 inches long, and each DVD is 5/8 inches thick.

Dividing the length of the shelf by the thickness of each DVD:

36 inches / (5/8) inches

To divide by a fraction, we multiply by its reciprocal:

36 inches * (8/5 inches)

Simplifying the multiplication:

288 inches / 5 inches

Now we can divide:

288 inches / 5 inches = 57.6

Therefore, you can place approximately 57 DVDs on the shelf if each DVD is 5/8 inches thick.

Time = 18years

Principal P= ????

The expression for the compound interest is given bellow as

A=P(1+r)^t

4500= P(1+0.017)^18

4500= P(1.017)^18

4500= P*1.35

P= 4500/1.35

Make r the subject - picture underneath

Answers

Answer:

The answer is r = 6a / (5m² - 1).

Step-by-step explanation:

The steps are :

[tex]m = \sqrt{ \frac{6a + r}{5r} } [/tex]

[tex] {m}^{2} = \frac{6a + r}{5r} [/tex]

[tex]5r {m}^{2} = 6a + r[/tex]

[tex]5r {m}^{2} - r = 6a[/tex]

[tex]r(5 {m}^{2} - 1) = 6a[/tex]

[tex]r = \frac{6a}{5 {m}^{2} - 1 } [/tex]

Answer:

r = [tex]\frac{6a}{5m^2-1}[/tex]

Step-by-step explanation:

Given

m = [tex]\sqrt{\frac{6a+r}{5r} }[/tex] ( square both sides )

m² = [tex]\frac{6a+r}{5r}[/tex] ( multiply both sides by 5r )

5rm² = 6a + r ( subtract r from both sides )

5rm² - r = 6a ← factor out r from each term on the left side

r(5m² - 1) = 6a ← divide both sides by (5m² - 1)

r = [tex]\frac{6a}{5m^2-1}[/tex]
