The decimal number 0.0014 can be written in standard form (also known as scientific notation) as 1.4 x 10^-3. This is done by shifting the decimal place so that you have a number between 1 and 10, and then indicating how many places you moved the decimal in the exponent of ten.

The student asked to convert the decimal 0.0014 into standard form. The standard form for representing decimal numbers involves using the scientific notation which means expressing numbers as a number between 1 and 10, multiplied by the power of ten. So, 0.0014 can be written as 1.4 x 10^-3 in standard form.

Step-by-step explanation:

Answer:

B= [tex]\frac{2A}{H}[/tex]

Step-by-step explanation:

If you noticed, A= [tex]\frac{1}{2}[/tex]BH is the formula for finding the area for a triangle. Your goal is to get B by it's self. Your first step will be to clear of the fraction first, so you will multiply both sides by 2.   2(A)=2([tex]\frac{1}{2}[/tex]BH).    On the left, you have 2×A= On the right side, you have     2([tex]\frac{1}{2}[/tex]BH),     but since you have a number in the equation, you will only use 2×[tex]\frac{1}{2}[/tex]. To solve  2×[tex]\frac{1}{2}[/tex], you will cnacel out both 2's and you have 1. 1×BH will still equal BH, so you are now left will B×H.

(Your new equation looks like this by the way).    2A=BH

Since you need to get B by its self, the way to clear the H away from the B is by dividing.  You will now divide the B and H aswell as 2A and H. (It will look like this) [tex]\frac{2A}{H} = \frac{BxH}{H}[/tex] . (Again when you have the same number or letter, you cross it out. When you divide, you won't change anything on the left side, and all you have to do on the right id to cross out the H next to the B and cross out the H on the bottom of the equation). You should be left with [tex]\frac{2A}{H}[/tex] = B. Now you can turn it around for your final answer. B= [tex]\frac{2A}{H}[/tex].

Answer:

Part A) [tex]A_s=\frac{\pi r^{2}}{360^o}{\theta}[/tex]

Part B) option 1,option 4

Step-by-step explanation:

Part A) Derive the formula for the area of a sector

we know that

The area of circle is equal to

[tex]A=\pi r^{2}[/tex]

The area of circle subtends a central angle of 360 degrees

so

using proportion

Find out the area of a sector  [tex]A_s[/tex]  by a central angle of ∅ degrees

[tex]\frac{\pi r^{2}}{360^o}=\frac{A_s}{\theta}[/tex]

[tex]A_s=\frac{\pi r^{2}}{360^o}{\theta}[/tex]

Part B) Verify each case

case 1) we have

radius = 5 cm

angle = 120°

area = 26.2 cm 2

Find the area of the sector and then compare with the value of the given area

assume

[tex]\pi=3.14[/tex]

substitute the given values

[tex]A_s=\frac{(3.14)(5)^{2}}{360^o}{120^o}[/tex]

[tex]A_s=26.2\ cm^2[/tex]

so

The given value of area is correct

case 2) we have

radius = 4 cm

angle = 105°

area = 16.7 cm 2

Find the area of the sector and then compare with the value of the given area

assume

[tex]\pi=3.14[/tex]

substitute the given values

[tex]A_s=\frac{(3.14)(4)^{2}}{360^o}{105^o}[/tex]

[tex]A_s=14.7\ cm^2[/tex]

so

The given value of area is not correct

case 3) we have

radius = 6 cm

angle = 85°

area = 23.7 cm 2

Find the area of the sector and then compare with the value of the given area

assume

[tex]\pi=3.14[/tex]

substitute the given values

[tex]A_s=\frac{(3.14)(6)^{2}}{360^o}{85^o}[/tex]

[tex]A_s=26.7\ cm^2[/tex]

so

The given value of area is not correct

case 4) we have

radius = 7

angle = 75°

area = 32.1 cm 2

Find the area of the sector and then compare with the value of the given area

assume

[tex]\pi=3.14[/tex]

substitute the given values

[tex]A_s=\frac{(3.14)(7)^{2}}{360^o}{75^o}[/tex]

[tex]A_s=32.1\ cm^2[/tex]

so

The given value of area is correct

Option E

The sum of all possible values of y is 20

Solution:

Given that,

6x + 2y = 25

Where, xy > 0

We have to find the sum of all possible values of y if x is a positive integer

We can use values of x = 1, 2, 3, 4

For x = 5 and above, y will be negative

Substitute x = 1 in given equation

6(1) + 2y = 25

6 + 2y = 25

2y = 25 - 6

2y = 19

Divide both the sides of equation by 2

[tex]y = \frac{19}{2}[/tex]

Substitute x = 2 in given equation

6(2) + 2y = 25

2y = 25 - 12

2y = 13

Divide both the sides of equation by 2

[tex]y = \frac{13}{2}[/tex]

Substitute x = 3 in given equation

6(3) + 2y = 25

2y = 25 - 18

2y = 7

Divide both the sides of equation by 2

[tex]y = \frac{7}{2}[/tex]

Substitute x = 4 in given equation

6(4) + 2y = 25

24 + 2y = 25

2y = 25 - 24

2y = 1

Divide both the sides of equation by 2

[tex]y = \frac{1}{2}[/tex]

Now add all the values of "y"

[tex]\text{Sum of possible values of y } = \frac{19}{2} + \frac{13}{2} + \frac{7}{2} + \frac{1}{2}\\\\\text{Sum of possible values of y } = \frac{19+13+7+1}{2}\\\\\text{Sum of possible values of y } = \frac{40}{2}=20[/tex]

Thus sum of all possible values of y is 20

Answer:

Question 1: A. 2

Question 2: C. [tex]x>90[/tex]

Step-by-step explanation:

Question 1:

Amount to be spend = $625

Cost to rent the ball room for 3 hrs = $350

Cost of each additional hour = $125

Ms Jensen wrote the Inequality as,

[tex]625>350+125h[/tex]

h⇒ Number of additional hours.

We need to find the value of 'h'.

Solution:

[tex]625>350+125h[/tex]

Now Subtracting both side by 350 using subtraction property of Inequality we get;

[tex]625-350>350+125h-350\\\\275>125h[/tex]

Dividing both side by 125 using Division property of Inequality we get;

[tex]\frac{275}{125}>\frac{125h}{125}\\\\2.2>h[/tex]

Hence The value of 'h =2' make the Inequality true.

Question 1:

Given:

[tex]20+2<\frac{x}{3}-8[/tex]

We need to find the solution for Inequality.

Solution:

First we will add the like terms we get;

[tex]22<\frac{x}{3}-8[/tex]

Now Adding both side by 8 using addition property of Inequality we get;

[tex]22+8<\frac{x}{3}-8+8\\\\30<\frac{x}{3}[/tex]

Now multiplying both side by 3 Using multiplication property of Inequality we get;

[tex]30\times3<\frac{x}{3}\times 3\\\\90<x[/tex]

Hence The solution to given Inequality is [tex]x>90[/tex].
