Is 70 thousand written in standard form or word form ? Explain

1 answer:

5 0

<span>70 thousand is written in short word form, because its written as a combination of numbers and letters. Standard form would be to write the number easily using multiplication with 10. That woul be: 70000=7*10^4. It;s 10^4 because the decimal point has been 4 laces to the left to get the number to be 7. Word form can be obtain by writing the number using letters. Long word form is: seventy thousand. But because sevety is written with number (70), this is short word form of the number,</span>

The sale price S (in dollars) of an item is given by the formula

S=L−rL , where L is the list price (in dollars) and r is the discount rate.

Since, S = L -rL

rL = L -S

r = $\frac{L-S}{L}$

r = $1-\frac{S}{L}$

Since, the listed price of the shirt is $30, we have to find the discount rate.

Therefore, r = $1-\frac{S}{30}$ is the discount rate.

A large washer has an outer radius of 10mm and a hole with a diameter of 14mm. What is the area of the top surface of the washer

choli [55]

<h2>Answer:</h2>

The area of the top surface of the washer is: 160.14 square mm.

<h2>Step-by-step explanation:</h2>

The top of the surface is in the shape of a annulus with a outer radius of 10 mm and a inner radius of 7 mm ( since the diameter of the hole is: 14 mm and we know that the radius is half of the diameter)

Now, we know that the area of the annulus region is given by:

$Area=\pi (R^2-r^2)$

where R is the outer radius and r is the inner radius.

Here we have:

$R=10\ mm\\\\and\\\\r=7\ mm$

Hence, we have:

$Area\ of\ top\ surface=\pi (10^2-7^2)\\\\i.e.\\\\Area\ of\ top\ surface=\pi (100-49)\\\\i.e.\\\\Area\ of\ top\ surface=\pi\cdot 51\\\\i.e.\\\\Area\ of\ top\ surface=160.14\ mm^2$

Imran deposited 3000 per month (at the start of month) into a saving account for 10 months. If the bank offer 6% interest compou

AnnZ [28]

Answer:

3.590.04

Step-by-step explanation:

The formula given for total amount saved when compounding interest =

A = P(1 + r/n)^nt

Where

A = Total amount saved after t years

P = Principal or initial amount saved

r = Interest rate

n = compounding frequency

t = time in years

From the above question

P = 3000

r =6% = 0.06

n =compounded monthly = 12

t = 3 years

Hence,

A = 3000(1 + 0.06/12)^3 × 12

A = 3000(1 + 0.06/12)^36

A = 3,590.04

Therefore, the total amount Imran will have in his account after 3 years = 3,590.04

1.Design a number line containing five (5) points 2.Benin, one of the smallest count pinstripes in Africa, has a total area of 4

gtnhenbr [62]

1.Design a number line containing five (5) points
For this case what you should do is place a line with five points.
You can think of one of the axes of the Cartesian plane, for example, the x-axis. We place five separate points in that line the same distance.
line: 0 1 2 3 4 5

a. Round off the total population to the nearest hundred thousand people
nearest hundred thousand means
100,000
Then rounding off we have:
10,160,555
hundred thousand: 10,161,000
b. Round off Benin's area in square miles to the nearest thousand.

nearest thousand means
1,000
Then rounding off we have:
43,475
thousand: 44,000

Round off the number of miles of surfaced roads to the nearest ten. nearest ten means
10
Then rounding off we have:
870
ten: 870

d. Round off the number of people who live in rural areas to the nearest million
nearest million means
1,000,000
Then rounding off we have:
3,657,790
million: 4,000,000
