Answer:

5.25

Step-by-step explanation:

7 - 1.75 = 5.25

Answer:

s = 5.25

Step-by-step explanation:

7 = s + 1.75

Subtract 1.75 from both sides.

7 - 1.75 = s + 1.75 - 1.75

5.25  = s

Answer:

It is A: 1/36

Step-by-step explanation:

With one cube the probability for it to land on 1 is 1/6. But when you add another cube in there you are multiplying the 1/6 by 2 which gives you 1/36

Answer:

  15

Step-by-step explanation:

||3v|| = ||(-9, 12)|| = √((-9)² +12²) = √225

||3v|| = 15

Additional comment

The (3, 4, 5) Pythagorean triple shows up in numerous algebra, geometry, and trigonometry problems. This is one of them. Once you identify the magnitude of v as the hypotenuse of a triangle with legs 3 and 4, you know immediately that ||v|| = 5 and ||3v|| = 15.

#1. 4x^2 + 17 - 15 = 0

Use the roots given, and plug them in to a factored form. Then, foil! It can also be helpful to multiply the equation to get rid of decimals/fractions.

(x - 3/4)(x + 5) = 0

x^2 - 3/4x + 5x - 3 3/4 = 0

x^2 + 4.25 - 3.75 = 0 (multiply everything by 4)

4x^2 + 17 - 15 = 0

#2. y = 0, -4

Both 4y^2 and 16y contain a 4 in the coefficient and a y in the variables. Therefore, we can factor out a 4y from each.

4y(y + 4) = 0

Then, set both parts of the factored equation equal to 0.

4y = 0

y = 0

y + 4 = 0

y = -4

#3. a = 0, -3

Both 6a^5 and 18a^4 contain a 6 in the coefficient and an a in the variables. Therefore, we can factor out a 6a^4 from each.

6a^4(a + 3) = 0

Then, set both parts of the factored equation equal to 0.

6a^4 = 0

a = 0

a + 3 = 0

a = -3

#4. x = -8

We are looking for two terms that multiply to equal a * c, and add up to equal b. We know that 8 + 8 = 16, and 8 * 8 = 64. There are no negatives in this equation, therefore both signs in our factored form are positive.

(x + 8)(x + 8) = 0

x + 8 = 0

x = -8

#5. x = -8, 8

First, subtract 64 from both sides. The key word here is 'factoring.' If this was not present, there is a different way (which may be easier for some).

x^2 = 64

x^2 - 64 = 0

Next, use the difference of two squares property to factor (x - c)(x + c), and set the two binomials equal to 0.

(x - 8)(x + 8) = 0

x - 8 = 0

x = 8

x + 8 = 0

x = -8

Hope this helps!! :)

Answer:

question 4 = 5

the mobile is of equal weight you have 5 of one item which is 5 X 4 = 20. there are 4 circles so 20/4 = 5

question 5 = 16

again mobile is shown to be equal you have 16 altogether on one side therefore the hexagon = 16

question 6 = 3

you are told there is 18 on each side.

you've already been given the leaf worth 6

18/2 = 9

9-6 = 3

star = 3

question 7 diamond = 2, heart = 12

again the mobile is shown to be equal. the mobile is a total 24, you've already been given 12 so the heart is = to 12 the other side both sides need to add up to 6 to make 12 so the diamond = 2

question 8 diamond = 3, heart = 16

44/2 = 22

22/2= 11

both sides need to add up to 22

Answer:

8,64,216,512

Step-by-step explanation:

Answer:

a/b = 2

so , a = 2b

b/c = 3/4

so , c = 4b/3

c/a = (4b/3) / 2b

which gives 2/3

Step-by-step explanation:

Step-by-step explanation:

[tex] \frac{b}{c} = \frac{3}{4} \\ 3c = 4b \\ c = \frac{4b}{3} [/tex]

[tex] \frac{a}{c} = 2 \\ a = 2b[/tex]

Answer:

4. Obtuse

5. Right

6. Acute

Step-by-step explanation:

Pythagorean Theorem.

a^2 + b^2 = c^2

a + b > c = Acute

a + b < c = Obtuse

a + b = c = Right

Answer:

$1320

Step-by-step explanation:

Given data

Cost of two ounces =$2,640

Let the cost of one ounce be x

So if 2 ounces cost $2,640

1 ounces will cost x

Cross multiply

2x=$2,640

Divide both sides by 2

x=$2,640/2

x=$1320

18 + 42 = 60 total question

what percent of 60 is 18 then

18 / 60 = .30*100 = 30%   :)

Answer: 43 3/4

Step-by-step explanation:

Reduce means simplify

43.75= 43 75/100

you can dive each side of 75 and 100 by 5

it will get you to 43 15/20

again it is not reduced dived by five once more

it will get you to 43 3/4

Answer: Yes, this is a function, and the function is:

population = y = f(d) = 5*(2)^d

Step-by-step explanation:

If the population doubles each day, we will have an exponential growth, that can be written as

f(d) = A*(r)^d

Where:

A is the initial population. (in this case 5)

r is the rate of growth.

d is our variable, in this case the number of days

then:

f(d) = 5*(r)^d

such that:

f(0) = 5*(r)^0 = 5

after one day, we should have the double of 5, this is 10:

f(1) = 10 = 5*(r)^1 = 5*r

10 = 5*r

10/5 = r

2 = r

Then the equation that tells the population of bacteria is:

y = f(d) = 5*(2)^d  (at least for the first four days, we do not know what happens after that)

Is the population of bacteria a function of the number of days?

Yes, this is a function because for each input d, we have only one output y.

Answer:

y = 3x - 13

Step-by-step explanation:

slope of line segment is -1/3 so a segment perpendicular to this would need a slope of 3

the midpoint for the segment is (2, -7); midpoint formula is [([tex]x_{1}[/tex]+[tex]x_{2}[/tex]/2), ([tex]y_{1}[/tex]+[tex]y_{2}[/tex]/2)]

using slope of 3 and point (2, -7) we can plug into y = mx + b

-7 = 3(2) + b

-7 = 6 + b

b = -13
