Question

To express ​7.5 % as a​ decimal, _______, ___________ and remove the percent sign.

▼ move the decimal point  [two] [three] [one] places to the [left] [right]

▼ leave the number as it is.

▼ remove the dollar sign.

▼ divide by 100.

Answer:

▼ move the decimal point  [two] places to the [left]

▼ divide by 100.  

Step-by-step explanation:

Given

[tex]Number = 7.5\%[/tex]

Required

Express as decimal [Select all correct options]

From the list of given options, the correct options are:

▼ move the decimal point  [two] places to the [left]

▼ divide by 100.  

To prove that the options are correct:

(1)

▼ move the decimal point [two] places to the [left]

7.5% becomes 0.075%

▼ Remove the percent sign

0.075% becomes 0.075

So:

[tex]7.5\% = 0.075[/tex]

(2)

Divide by 100

7.5% when divided by 100 is: 0.075%

Remove the % sign, we have: 0.075

Answer:

B

Step-by-step explanation:

Hey There!

they are asking for the equation in slope intercept form

Slope intercept form is y=mx+b

where m equals slope and b equals y intercept

to find the slope we do change in y over chang in x

as y goes up 2 x goes down 5 so the slope would be -2/5

the y intercept is at (0,4) so the y intercept is 4

now we add everything together and get that the equation in slope intercept form is

y=-2/5x+4

so we can conclude that the answer is B

Answer:

Step-by-step explanation:

A line can be expressed as

y=mx+b, where m is the slope and b is the y intercept (the value of y when x=0)

Any two points form a line when connected.

m=(y2-y1)/(x2-x1), in this case we have points (0,4) and (5,2) so

m=(2-4)/(5-0)

m=-2/5 so our line is now

y=-2x/5+b, using (5,2) we can solve for b

2=-2(5)/5+b

2=-2+b

b=4, so the line is

y=-2x/5+4

Answer B

Answer:

The real solutions are : -6, -3 and 2

Step-by-step explanation:

The solutions of a functions are the input values at an output zero

Graphical wise, this can be represented by the order pairs (x, 0)

In other words, these are the points that lie on the x-axis

Examining the given graph, we can see that the points lying on the x-axis are:

(-6, 0), (-3, 0) and (2, 0)

This means that:

The real solutions of the function are:

-6, -3 and 2

Hope this helps :)

Answer:

x=6

Step-by-step explanation:

The two triangles shown are similar (AAA: they share the angle on the right and the two other angles are corresponding and therefore equal).

Since, they're similar, the sides are in ratio to eachother:

[tex]\frac{x+(x+3)}{8+12} = \frac{x+3}{12}[/tex]

12(2x+3)=20(x+3)

24x+36=20x+60

4x=24

x=6

Step-by-step explanation:

On simplifying its

M2 + 10m - 56 = 0.......... (divide both side by 3)

M2 - 4m + 14m - 56=0

M(M-4) + 14(m-4) =0

(M+14) + (m-4)=0

M =4, - 14.

If the condition is given that you cannot put m's value negative. Than the answer is M=5....

THANKU

Answer:

m = 4

m = -14

Step-by-step explanation:

here's your solution

=> 3m^2 + 30m - 168

=> firstly we will make it in simplest form

=> take 3 common

=> 3(m^2 + 10m - 56)

=> we get , (m^2 + 10m - 56)

=> now, factories it by using middle term split

=> m^2 + 14m - 4m - 56

=> now take common

=> m(m + 14) - 4(m + 14)

=> (m - 4) (m + 14)

=> m - 4 = 0

=> m= 4

=> (m+14) =0

=> m = -14

Answer:

(x-17)*(-7)=-140

x-17=20

x=37

Step-by-step explanation:

Answer:

37

Step-by-step explanation:

-140 ÷ - 7

= 20 (the difference)

20 + 17

= 37

Answer: 240

Step-by-step explanation:

2x36)/2=36

(36+39)x2/2=75

(31+39)x2/2=70

(14+31)x2/2=45

(2x14)/2=14

14+45+70+75+36=240

Answer:

60 people

Step-by-step explanation: Multiply 20 by 3 and you will get 60, which is the total combonation of people.

Answer:

6840 I think.

Step-by-step explanation:

There's 20 people in the race, it's asking for how many possibilities there are for each person to end up as 1st, 2nd, & 3rd.

Problems like these are solved by 20! (20x19x18xetc till 1) over (the number of competitors (20) minus the number of prized places (3)). 20-3=17.

20! over 17!.

Sorry if it's wrong but it's how I remember it to be.

Answer:

  91 rad/s

Step-by-step explanation:

The relationship between angular velocity (ω) and constant angular acceleration (ω') is ...

  ω(t) = ω0 + t·ω'

  ω(0.25) = 95 = ω0 + 0.25(16)

  95 -4 = ω0 = 91 . . . rad/s

The initial angular speed was 91 radians per second.

Answer:

Part A; Initial dosage is 10 milligrams

Part B:

8.4113 milligrams after 1 hour

5.0057 milligrams after 4 hours.

Step-by-step explanation:

It is given M(h)= 10 [tex]e^{-0.173h}[/tex]

Initial dosage is the 10 milligrams

After 1 hour, plug in h as 1

So, M(1)=10[tex]e^{-0.173*1}[/tex]

Simplify the right side

M(1)=10(0.84113)

M(1)= 8.4113 milligrams.

Now, after 4 hours

M(4)=10 [tex]e^{-0.173*4}[/tex]

M(4)=10(0.50057)

M(4) =5.0057 milligrams

angle 1 — 90

angle 2 — 180 - (90 + 63) = 27

angle 3 — 180 - (90 + 54) = 36

Answer:

40 cups

Step-by-step explanation:

7 part nuts and 2 parts M&M makes up 1 trail mix

7 and 2 part = 9 parts in total

There are 180 cups in total, so each part would be:

180/9 = 20 cups = 1 part

Now, we know there are 2 parts M&Ms and there are 20 cups in a part, so:

M&Ms required = 2 * 20 = 40 cups

Answer:

$40

Answer:

  C +2D = 3s -21

Step-by-step explanation:

Use the substitution property of equality.

  C = s -5

  D = s -8

Then the value of your expression is ...

  C +2D = (s -5) +2(s -8)

  = s -5 +2s -16

  C +2D = 3s -21
