Answer: 49

Step-by-step explanation:

[tex]-11\frac{2}{3}*-4\frac{1}{5}[/tex]

The first thing we are going to do is to convert to an improper fraction. To do this, you take the whole number, you multiply it by the denominator and add the numerator; all over the same denominator.

[tex]-\frac{11*3+2}{3}*-\frac{4*5+1}{5}[/tex]

Solve;

[tex]-\frac{33+2}{3}*-\frac{20+1}{5}[/tex]

[tex]-\frac{35}{3}*-\frac{21}{5}[/tex]

Now you can simply multiply numerators and denominators. Also, remember the negative signs which become positive because -*-=+

Before multiplying, it's easier to solve fractions that are being multiplied if you simplify them.

35 and 5 can be simplified.

35/5=7

5/5=1

21 and 3 can be simplified.

21/3=7

3/3=1

Leaving our multiplication as:

Answer:

y+3x+11=0

Step-by-step explanation:

m=-3, x1=-4, y1=1

from m=y-y1/x-x1

-3=y-1/x-(-4)

-3(x+4)=y-1

-3x-12+1=y

y=-3x-11

Answer: 35 hours

Step-by-step explanation: 450-100 because of the advanced pay, then you dived 350 by ten so you get 35 hours

Answer:

Sandy needs to babysit for 35 hours to earn enough money to buy an Iphone.

Explanation:

Sandy gets $100 advance pay and $10 per hour for babysitting.

Let x denotes the number of hours then  

10x + 100

Sandy wants to buy an Iphone for $450

10x + 100 = 450

Solving the above equation

10x = 450 - 100

10x = 350

x = 350/10

x = 35 hours

Therefore, Sandy needs to babysit for 35 hours to earn enough money to buy an Iphone.

Answer:

a) [tex] \mu -\sigma = 8500 -1500 = 7000[/tex]

[tex] \mu +\sigma = 8500 +1500 =10000[/tex]

[tex] \mu -2*\sigma = 8500 -2*1500 = 5500[/tex]

[tex] \mu +2*\sigma = 8500 +2*1500 =11500[/tex]

[tex] \mu -3*\sigma = 8500 -3*1500 = 4000[/tex]

[tex] \mu +3*\sigma = 8500 +3*1500 =13000[/tex]

On the figure attached we have the illustration for required showing the percentages and the limits for each case

b) [tex] z= \frac{6000-8500}{1500}= -1.67[/tex]

And using the normal standard table or excel we got:

[tex] P(Z<-1.67) = 0.047[/tex]

Step-by-step explanation:

For this case we have the following properties:

[tex] \mu = 8500, \sigma = 1500[/tex]

Part a

And for this case from the empirical rule we know that within one deviation from the mean we have 68% of the values , within two deviation 95% and within 3 deviations 99.7%. So then we can find the limits like this:

[tex] \mu -\sigma = 8500 -1500 = 7000[/tex]

[tex] \mu +\sigma = 8500 +1500 =10000[/tex]

[tex] \mu -2*\sigma = 8500 -2*1500 = 5500[/tex]

[tex] \mu +2*\sigma = 8500 +2*1500 =11500[/tex]

[tex] \mu -3*\sigma = 8500 -3*1500 = 4000[/tex]

[tex] \mu +3*\sigma = 8500 +3*1500 =13000[/tex]

On the figure attached we have the illustration for required showing the percentages and the limits for each case

Part b

For this case we want to find this probability:

[tex] P(X<6000)[/tex]

We can calculate the number of deviation below the mean with the z score formula given by:

[tex] z = \frac{X -\mu}{\sigma}[/tex]

And replacing we got:

[tex] z= \frac{6000-8500}{1500}= -1.67[/tex]

And using the normal standard table or excel we got:

[tex] P(Z<-1.67) = 0.047[/tex]

Answer:

0.28

Step-by-step explanation:

The sum of the geometric value progression is S = 0.28

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the sequence be A = { 1 - 0.99 + 0.99² - 0.99³... - 0.99⁷⁹ }

So , A = 1 - { 0.99 - 0.99² + 0.99³... + 0.99⁷⁹ }

Let the first term of the GP be a₁ = 0.99

Now , the common ratio of GP , r = 0.99

And , the number of terms in GP = 80

And , Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

On simplifying , we get

S₈₀ = 0.99 ( 1 - 0.99⁸⁰ ) ( 1 - 0.99 )

On further simplification , we get

S₈₀ = 0.7224

So , the sum of the GP is S = 1 - S₈₀ = 0.28

Hence , the sum of GP is 0.28

good news, the second one is relatively easy because it can be factored to (2x+1)(2x-3) which means that number two has solutions of -1/2 and 3/2

but for number one you have to either use the quadratic equation cause I've tried using synthetic division or just use the second equation to derive the first solutions so I tried move the graph up by two units and found that the intercepts are approximately (1+-√2)/2 or 1/2+-1/√2 for 4x^2-4x-1

Answer:

Micah can put 61072.56 ml³ of water in his cup.

Step-by-step explanation:

The volume of a cone is given by the following formula:

[tex]V = \frac{h\pi r^{2}}{3}[/tex]

In which h is the height and r is the radius.

The radius is half the diameter.

In this question:

Radius of 72/2 = 36 ml. So [tex]r = 36[/tex]

Height of 45 ml, so [tex]h = 45[/tex]

The dimensions are in ml, so the volume will be in ml³.

So

[tex]V = \frac{h\pi r^{2}}{3}[/tex]

[tex]V = \frac{45\pi*(36)^{2}}{3}[/tex]

[tex]V = 61072.56[/tex]

Answer:

Step-by-step explanation:

Let the sailboats be s and the dinghies be d.

We have that:

s : d = 5 : 7

In other words:

s / d = 5 / 7

If there are 70 sailboats, this implies that s = 70

=> 70 / d = 5 / 7

=> d = (70 * 7) / 5 = 490 / 5 = 98

There will be 98 dinghies.

[tex]25x^2 - 36\\(5x ) (5x )[/tex]

Since 36 is negative, we have to have a positive 6 and a negative 6:

Answer:

19 feet

Step-by-step explanation:

First we must make the scale make sense, that is, it is in the same unit, therefore, we will pass 3 inches to feet, we know 1 foot is 12 inches, therefore:

3 inches * 1 foot / 12 inches = 0.25 feet

Which means that the real equivalence is 0.25: 8, now they are 7 inches, therefore:

7 inches * 1 foot / 12 inches = 0.583333

Now, we calculate the number of actual feet using the scale.

0.583333 * 8 / 0.25 = 18.66 feet

that is to say that the length of the current Kitchen is 19 feet if we round
