a) Write 5.1 x 10¹ as an ordinary number.
b) Work out the value of (1.7 x 10¹) × (8.5 × 10-²)
Give your answer in standard form.

Answers

Answer 1

On solving the provided question we can say that ordinary number the answer is  1.495 x 10^0

What is an ordinary number?

An ordinary number, also known as a standard form number or a decimal number, is a number that is written in the familiar base-10 format, with a whole number part and a fractional part separated by a decimal point.

A) 5.1 x 10¹ as an ordinary number is 51.

B) To work out the value of (1.7 x 10¹) × (8.5 x 10-²), we first need to multiply the two numbers:

(1.7 x 10¹) × (8.5 x 10-²) = 1.7 x 8.5 x 10¹ x 10-² = 14.95 x 10-1

To express the answer in standard form, we need to move the decimal point to the left so that there is only one non-zero digit to the left of it. 14.95 x 10-1 is 1.495 x 10^0. So the answer is 1.495 x 10^0

Answer:

65   3    46

Step-by-step explanation:

Answer:

a² + 1 = 65

18/2a = 3

6(d + 8) - 10d = 46

Step-by-step explanation:

a² + 1 when a = 8

first, plug in 8 for a.

a² + 1 ⇒ 8² + 1

begin simplifying by finding , which is just 8 · 8.

+ 1 ⇒ 64 + 1

finish simplifying by adding 64 + 1.

64 + 1 = 65

therefore, when a = 8, a² + 1 = 65.

18/2a when a = 3

first, plug in 3 for a.

18/2a ⇒ 18/2(3)

begin simplifying by multiplying 2 · 3.

18/2(3) ⇒ 18/6

finish simplifying by dividing 18 ÷ 6.

18/6 = 3

therefore, when a = 3, 18/2a = 3.

6(d + 8) - 10d when d = 1/2

(i'm going to convert 1/2 to 0.5 because i prefer working with decimals rather than fractions)

so... 6(d + 8) - 10d when d = 0.5

first, plug in 0.5 for d.

6(d + 8) - 10d ⇒ 6(0.5 + 8) - 10(0.5)

begin simplifying by distributing 6 to 0.5 and 8, which is just 6 · 0.5 and 6 · 8.

6(0.5) = 36(8) = 48

after distributing, your expression is 3 + 48 - 10(0.5).

continue simplifying by multiplying -10 · 0.5.

3 + 48 - 10(0.5) ⇒ 3 + 48 - 5

add 3 + 48.

3 + 48 - 5 ⇒ 51 - 5

finally, finish simplifying by subtracting 5 from 51.

51 - 5 = 46

therefore when d = 1/2 or 0.5, 6(d + 8) - 10d = 46.

find the measure of the missing angle​

Answers

Answer:

50

Step-by-step explanation:

40 plus 90 equals 130 and triangle must be 180 so we need 50 degree

50°

Let x be the missing angle.

90°(right angle) + 40°(given) + x = 180° ( the sum of degrees of interior angles of triangle)

x = 180°-130°

x = 50°

Step-by-step explanation:

Hello!

I think I can help.

Lets use the first problem and walk through it and I think it could help you with the others.

3/7 = ?/49

So basically with these problems you are working backwards. You are working right to left and dividing to figure out what you will need to multiply the other part of the fraction by.

So here we have 49 and 7 that line up with each other. (Always look for the fractions that line up horizontally)

Going right to left and dividing :

49 / 7

= 7

So we know that it was 7 x 7 to get that 49

So now we used the number we just found by dividing (7) and multiply it left to right by the other number to find the missing number (?).

If we do this we do :

3 x 7

= 21

And that is the missing number !

We plug that in right where the blank is (?) and we get :

3/7 = 21/49

I am not sure if you have to simplify this but you cant anyways. If you have questions about simplifying ask in the comments.

To check this we can actually multiply the side that had two numbers to begin with (the left side numbers) and multiply it by the number we found by dividing (7).

So we do this with 3/7 :

3 x 7 = 21

7 x 7 = 49

if we plug this back in we get :

21/49 = 29/49 and we know this is correct.

I hope this helps you solve the other problems. If you have any questions or are still confused with others please message me or comment and I will do what I can to help.  :)

Please help, this is due soon

Determine a differential equation for the number x(t) who have contracted the fluif the rate at which the disease spreads is proportional to the number of interactions between the number of students who have the fluand the number of students show have not been exposed to it.

Answers

Answer:

[tex]\frac{dx}{dt}[/tex] = k.x.[1000 - x] ;  

where k is the proportionality  constant

Step-by-step explanation:

Let

The number of people who are infected with the flu = x(t)

Total number of students = 1000

So,

Total number of student who do not expose with the flue = 1000 - x(t)

As given,

We have to find the differential equation such that

The rate at which the disease spreads is proportional to the number of interactions between the number of students who have the flu and the number of students show have not been exposed to it.

⇒[tex]\frac{dx}{dt}[/tex] ∝ x(t) . [ 1000 - x(t) ]

⇒[tex]\frac{dx}{dt}[/tex] = k.x.[1000 - x] ; where k is the proportionality  constant

Bonnie has 4 sharpened and 8 unsharpened pencils in her pencil case. She randomly selects 2 of the pebcils from the box without replacement. What is the probability that both pencils will be sharpened? A. 1/2 B.1/9 C. 4/33 D.1/11

Answers

Answer:

D. 1/11.

Step-by-step explanation:

There are 12 pencils in the case.

Prob( first one is sharpened) = 4/12 = 1/3

Prob(second is sharpened) = 3/11

Prob(both sharpened) = 1/3 * 3/11

= 3/33

= 1/11.

The probability is 1/11 that both pencils will be sharpened which is the correct option(D).

What is probability?

The probability is defined as the possibility of an event being equal to the ratio of the number of outcomes and the total number of outcomes.

Given that,

Bonnie has 4 sharpened and 8 unsharpened pencils

So, there is a total of 12 pencils in the pencil case.

Let, the probability first one is sharpened is P(E₁)

The probability second one is sharpened is P(E₂)

P(E₁) = 4/12 = 1/3

P(E₂) = 3/11

Required probability both sharpened P(E) = P(E₁)×P(E₂)

Required probability both sharpened P(E) = 1/3 × 3/11

Required probability both sharpened P(E) = 3/33

Required probability both sharpened P(E) = 1/11.

Hence, the probability is 1/11 that both pencils will be sharpened.

Take the 0 out of the end of the 0.010 because there is no reason for it to be there.

Then you just multiply 81.04 by 1 because the rest of 0.01 is just zeros and the you get 81.04.

Then you count the decimal places in 0.01 which you get two so you move the decimal in 81.04 two times to the left.
