Which value of y makes the inequality 3y^2 +2(y-5)>8 true?

Answer:

Undefined

Step-by-step explanation:

Slope of the line

[tex] = \frac{ - 2 - 3}{ - 9 - ( - 9)} \\ \\ = \frac{ - 5}{ - 9 + 9} \\ \\ = \frac{ - 5}{0} \\ \\ = \infty \: \: or \: undefined[/tex]

Answer:

After the first 3 weeks Jeremiah saved $135. If the situation is proportional:

$135 : 3 = $ 45. It means that he can save $45 for one week.

Therefore an equation is:

s = 45 * w,

where s is the amount saved and w is the number of weeks.

After 8 weeks :

s = 45 * 8 = $360.

Step-by-step explanation:

6x100=600/15=40

Answer:

turn it into an equation

since the total number of students is 63 and for every 3 boys are 4 girls

3x + 4x = 63

7x = 63

x = 63/7

x= 9

to get the number of boys

3 x 9 = 27

therefore the number of boys is 27

Answer:

#5: 60

#6:55

#7:70

#8:55

11.81

Step-by-step explanation:

#5

∠CFD=60 (all the angles in an equilateral triangle are 60)

#6

∠AFD=150=∠AFB+∠BFC+∠CFD

∴150=∠AFB+35+60

∴∠AFB=55

#7

An isosceles triangle has one unique vertex angle and two equal base angles. All the angles in a triangle add up to 180. We know the base angles (55), so:

180 = ∠ABF + 2(55)

∴∠ABF = 70

#8

∠A=∠AFB = 55 (base angles of an isosceles triangle)

11. An isosceles triangle has one unique vertex angle and two equal base angles. All the angles in a triangle add up to 180. Vertex angle is 18, so the sum of both bases is 180-18=162. Therefore, each base angle is 81.

Answer:

[tex]tan165^0 = -2 + \sqrt{3}[/tex]

Step-by-step explanation:

Given;

tan165⁰

165⁰ is in the second quadrant, and sine is positive in this quadrant, thus tan will be negative.

In second quadrant, tanθ = -tan(180 - θ)

tan165⁰ = -tan(180-165)

tan165⁰ = -tan15⁰

[tex]- tan15^0 = -tan(60 - 45)\\\\ tan(\alpha - \beta) = \frac{tan \alpha -\ tan \beta}{1 + tan \alpha tan \beta}\\\\ -tan(60 - 45) = -(\frac{tan 60 - tan 45}{1+tan60tan45} )\\\\ -(\frac{tan 60 - tan 45}{1+tan60tan45} )= -(\frac{\sqrt{3} \ - 1}{1+ \ \sqrt{3} } ) = \frac{1 \ -\sqrt{3} }{1+ \ \sqrt{3} }\\\\\frac{1 \ -\sqrt{3} }{1+ \ \sqrt{3} } =( \frac{1 \ -\sqrt{3} }{1+ \ \sqrt{3} })(\frac{1 - \ \sqrt{3}}{1 - \ \sqrt{3}} ) = \frac{1-\sqrt{3} -\sqrt{3} \ +\ 3 }{1\ -\ 3} = \frac{4-2\sqrt{3} }{-2}[/tex]

[tex]\frac{4-2\sqrt{3} }{-2} = -2 + \sqrt{3}[/tex]

Therefore, [tex]tan165^0 = -2 + \sqrt{3}[/tex]

Answer:

On EDG

Using the binomial distribution, it is found that the probabilities are given as follows:

a) 0.2036 = 20.36%.

b) 0.0011 = 0.11%.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem, the parameters are given as follows:

p = 0.95, n = 5.

Item a:

The probability is P(X = 4), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 4) = C_{5,4}.(0.95)^{4}.(0.05)^{1} = 0.2036[/tex]

Item b:

The probability is:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2).

Then:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{5,0}.(0.95)^{0}.(0.05)^{5} \approx 0[/tex]

[tex]P(X = 1) = C_{5,1}.(0.95)^{1}.(0.05)^{4} \approx 0[/tex]

[tex]P(X = 2) = C_{5,2}.(0.95)^{2}.(0.05)^{3} = 0.0011[/tex]

Then:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0 + 0 + 0.0011 = 0.0011.

Answer:

Ratio is [tex]\frac{9}{6}[/tex]

You can simplify it of course to 3/2

Step-by-step explanation:

Volume of a cube is V = length^3 or l^3

Volume for larger cube = 729 cubic inches

Volume for smaller cube = 216 cubic inches

Surface area is S = 6*l^2

So we just need to find the length of each side of the cube.

We take the cube root for each cube volume since there are three sides.

Larger cube = 729^(1/3) = 9

smaller cube = 216^(1/3) = 6

Ratio is [tex]\frac{9}{6}[/tex]

Answer:

t = 0

Step-by-step explanation:

(7t - 2) - (-3t + 1) = -3(1 - 3t)

because you can not do anything inside the parantheses, you distribute. there aren't any numbers on the left side of the parantheses on the left side of the equation so we just imagine the number 1. on the right side of the equation, just distribute normally

[ 1(7t - 2) -1(-3t + 1) = -3(1 - 3t) ]

will be

7t - 2 + 3t - 1 = -3 + 9t

add like terms

10t - 3 = -3 + 9t

subtract 9t from both sides

t - 3 = -3

add 3 to both sides

t = 0

Answer:

1 Cup of Water

Step-by-step explanation:

Well, this is pretty simple.

This questions topic is known as Equivalent Ratios.

To find an equivalent ratio, add or divide the numbers by the same amount.

Let's do it together.

4:2 is the ratio we already have. If we have to make it have 2 cups of flour, let's divide 2 on both sides.

Since 4 divided by 2 is 2, and 2 divided by 2 is 1,

We can confirm that you would need to put in 1 cup of water.

Answer:

The integers are  9 and 22

Step-by-step explanation:

Step one:

given data

let the smaller integer be x

and the bigger be y

x+y=31-----------1

so

y=(2x+4)

Step two:

put y=(2x+4 in equation 1 we have

x+2x+4=31

3x+4=31

3x=31-4

3x=27

divide both sides by 3

x=27/3

x=9

the smaller integer is 9

the bigger is 2(9)+4= 18+4=22
