write each fraction number as a decimal 33/40

Answers

Answer:

0.825

Step-by-step explanation:

In order to make the denominator 100, we must multiply both the numerator and denominator by 2.5

33*2.5 = 66 + 16.5 = 82.5

33/40 = 82.5/100

Now we solve, 82.5/100 = 0.825

What is a line segment?

A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.

Given that the value of x and QR if Q is between P and R.

PQ=2x

QR=x + 2

PR= 5x -10

The value of x will be calculated as below:-

2x+x+2=5x-10

3x+2=5x-10

2=2x-10

12=2x

x = 12 / 2

x =6

The value of QR will be calculated as below:-

QR=x+2

6+2=8

Therefore, the value of x is 6 and the value of QR will be 8 units.

what is the midpoint of (4,5) and (9,17)

Answers

Answer:

Step-by-step explanation:

Midpoint formula: ( (x1+x2)/2, (y1+y2)/2)

where (x1, y1) and (x2, y2) are our points

Let (x1, y1) = (4, 5)

and (x2, y2) = (9, 17)

x1 = 4

x2 = 9

y1 = 5

y2 = 17

Then ( (4+9)/2, (5+17)/2 ) = (13/2, 22/2) = (13/2, 11)

**3. What is the y-intercept of the line that has a slope of
-4 and passes through the point (4, -6)?

Answers

Answer:

10

Step-by-step explanation:

We'll first write in point-slope form:

y - y1 = m(x - x1)

where (x1, y1) is our point and m is our slope.

Then convert into slope-intercept form to make it easier to find the y-intercept.

y - (-6) = -4(x-4)

y + 6 = -4(x-4)

y + 6 = -4x + 16

y = -4x + 10

Now that we've put the equation in slope-intercept form, we see that our b-value

y = mx + b

b = 10, so our y-intercept is 10

Given m||n, find the value of x.

The pyrite cube is, well, a cube, so it has a side length s such that the area of its base is

Then its volume is

s ³ = 13.824 cm³

Pyrite is also known as "fool's gold" because it looks a lot like gold. So if gold has a unit price of €785/cm³, then a pyrite cube with volume 13.824 cm³ could be mistaken for a gold cube of the same volume, which would sell for a price of

Bot #11

Step-by-step explanation:

If you picked bot 12 in 5 second it produces 21 clicks which means if you add another 5 second it will be 10 second with 42 clicks. But, if you pick the bot with 17 clicks per 4 second, 8 seconds it will already be 34 clicks and 10 seconds half of 17 is  8/5 which in 10 seconds it produces 42.5 which shows the first bot produces more.

Which equation represents a population of 250 animals that decreases at an annual rate of 21% ?

A. p = 250(1.21)
B. p = 250(1.79)
C. p= 250(0.79)
D. p=250(0.21)

Answers

Answer: Choice C.  p = 250(0.79)^t

Work Shown:

p = a*b^t

p = a*(1+r)^t

p = 250*(1+(-0.21))^t

p = 250(0.79)^t

Note that r = -0.21 is negative to indicate we have exponential decay.

A certain forest covers an area of 4900 km². Suppose that each year this area decreases by 7%. What will the area be after 8 years?
Use the calculator provided and round your answer to the nearest square kilometer.

Answers

Answer:

area after 8 years is 2156km²

Step-by-step explanation:

Area of forest=4900 km²

decrease in area in 1 year=4900km² × 7%

decrease in area in 1 year= 343km²

decrease area in 8 years=343km² × 8

=2744km²

Remaining area= (4900-2744)km²

=2156km²

A 10 1/2-inch candle burns down in 7 hours. If b represents how much of the candle, in inches, has burned away at any time given in hours, t, write a proportional equation for b in terms of t that matches the context.

Answers

The proportional formula for b is 3/2 in terms of t.

What is proportional equation?The equation y = kx represents a proportionate relationship between two quantities y and x that have the same proportionality constant, k. If an equation in another form can be rewritten as in the example above, then the relationship is proportional.Assume that b = kt is the equation.In light of the statement 10 1/2 = k.7So, k = 10 1/2 /7 =21/2 /7 => 3/2Therefore, the equation is b = 3/2t, where t is the proportionality factor.y = k x, where is the proportionality constant, is the equation that depicts a proportional relationship, or a line. Find k and create the equation by using k = y x from a table or graph. Tables, graphs, and equations can all be used to represent proportional relationships.

If a^2+b^2=13 and ab =6 find the value of
(i)(2a+2b)
(ii)(2a-2b)

Answers

Answer:

I)

[tex]2a + 2b = -10\text{ or } 2a + 2b = 10[/tex]

II)

[tex]2a - 2b = -2 \text{ or } 2a-2b= 2[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaytstyle a^2 + b^2 = 13 \text{ and } ab= 6[/tex]

I)

Recall the perfect square trinomial pattern:

[tex]\displaystyle (a+b)^2 = a^2 + 2ab + b^2[/tex]

Rewrite:

[tex]\displaystyle (a+b)^2 = (a^2 + b^2) + (2ab)[/tex]

Substitute:

[tex]\displaystyle (a+b)^2 = (13) + (12)[/tex]

Evaluate:

[tex]\displaystyle (a + b)^2 = 25[/tex]

Take the square root of both sides:

[tex]\displaystyle a + b = \pm\sqrt{25} = \pm5[/tex]

Hence:

[tex]\displaystyle 2a + 2b = \pm 10[/tex]

Therefore:

[tex]\displaystyle 2a + 2b = -10 \text{ or } 2a + 2b = 10[/tex]

II)

Likewise:

[tex]\displaystyle (a-b)^2 = a^2 - 2ab + b^2[/tex]

Substitute:

[tex]\displaystyle (a-b)^2 = (13) -(12)[/tex]

Solve:

[tex]\displaystyle \begin{aligned} (a-b)^2 &= 1 \\ a-b &= \pm \sqrt{1} \\ a-b &= \pm 1\\ 2a - 2b &= \pm 2\end{aligned}[/tex]

In conclusion:

[tex]2a - 2b = -2 \text{ or } 2a-2b= 2[/tex]
