Which three side lengths will NOT form a triangle?
a- 4cm, 2cm, 8cm
b- 5in, 8in, 4in
c- 2ft, 3ft, 6ft
d- 5m, 2m, 4m

Answer:

12

Step-by-step explanation:

So, the 24cm, is the diameter, a little circle autonomy here, the diameter is the length across the circle, and the radius is to the mid point, or half-way point, which means that the radius is half the diameter, so, 24 ÷ 2 = 12

hope this helps:)

Answer:

FV= $669.11

Step-by-step explanation:

Giving the following information:

Purchase price (PV)= $800

Decrease value (d)= 1.5% per year

Number of periods (n)= 12 years

To calculate the value of the card after 12 years, we need to use the following formula:

FV= PV / (1 + d)^n

FV= 800 / (1.015^12)

FV= $669.11

Answer:

Step-by-step explanation:

After some trial and error, we can find that x = 2 is one solution to this problem. We know that then (x-2) is a solution. We can then do polynomial division to get a quadratic equation. We can then solve the quadratic equation to get the other two factors which are -1/3 and -3/2. You can also graph it and find the roots as well. There isn't a really good method to do this and it is more like trial and error.

Step-by-step explanation:

Problem 5

-------------------------

Explanation:

When we increase some value by 7%, we are effectively multiplying by 1.07

Note how 100% + 7% = 107% = 1.07

The 1.07 multiplier is then handy to use algebra to find the cost before tax is added

x = cost before tax

1.07x = cost after tax

1.07x = 524.30

x = 524.30/1.07

x = 490

Before tax, the water heater cost $490.

If we apply a 7% tax, then we pay 7% of 490 = 0.07*490 = 34.30 dollars on top of the $490 to get 490+34.30 = 524.30 which matches with the instructions. So our answer is verified.

Or you could use the 1.07 multiplier shortcut to see that 1.07*490 = 524.30

======================================================

Problem 6

-------------------------

Explanation:

His gross pay is $1750. This is the amount he earned before any taxes are applied. The items of Medicare, Social Security, and Federal Withholding Income Tax, are all various taxes that Ian has to pay. So his gross pay will be reduced to some smaller value to get the net pay.

To find the total amount of taxes deducted from his paycheck, we add up the tax percentage values to get: 1.45+6.2+18 = 25.65

This means Ian is taxed at a total rate of 25.65% of his gross pay, and he has to pay 0.2565*1750 = 448.875 = 448.88 dollars to the government. This leaves 1750-448.88 = 1301.12 dollars left over for his net pay.

A slightly alternative way is to note how if Ian pays 25.65% of his gross pay, then he's left with 100% - 25.65% = 74.35% of his paycheck, and 0.7435*1750 = 1,301.125 which would round down to 1301.12

I'm rounding up when it comes to determining the amount of tax to pay, while rounding down any amount Ian has left over for his net pay. This ensures that we consider the worst-case scenario.

Answer:

D

Step-by-step explanation:

Probability is, by definition, a number between 0 and 1, which can be expressed as a fraction or a percentage. For example, the odds of getting heads if you throw a fair coin are 50%, or ½. The odds of not getting heads are 1-½=½.

If the probability of something happening is 1, it means that that thing will happen for sure. Likewise, if the probability of an event is 0, it means that the event will never happen.

You can therefore easily understand that it doesn't make sense to have a probability greater than 1, as we have in choice D.

Answer:

u = 23 and t = 6

Step-by-step explanation:

Given

u = 4v - 3t

(a)

u = 4(5) - 3(- 1) = 20 + 3 = 23

(b)

- 10 = 4(2) - 3t

- 10 = 8 - 3t ( subtract 8 from both sides )

- 18 = - 3t ( divide both sides by - 3 )

6 = t

Answer:

see explanation

Step-by-step explanation:

The function has a maximum value when sinx = 1 , then

y = 3(1) + 5 = 3 + 5 = 8

The function has a minimum value when sinx = - 1, then

y = 3(- 1) + 5 = - 3 + 5 = 2

Thus

range is 2 < y < 8

Answer:

9

Step-by-step explanation:

To solve this, you need to find the proportion.

p is a leg of the large triangle, and the leg to the small triangle is 6.

8 is another leg of the small triangle, and 8+4 is the leg of the large triangle.

So [tex]\frac{small triangle}{big triangle} = \frac{small triangle}{big triangle\\}[/tex]

[tex]\frac{8}{12} =\frac{6}{p}[/tex]

[tex]\frac{2}{3} =\frac{6}{p}[/tex]

cross multiply to get 2p=18

divide both sides by 2

p=9.

Answer:

[tex]\frac{11}{6}[/tex] units

Step-by-step explanation:

To find the x- intercepts let y = 0 , that is

6x² - 7x - 3 = 0 ← in standard form

(3x + 1)(2x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

3x + 1 = 0 ⇒ 3x = - 1 ⇒ x = - [tex]\frac{1}{3}[/tex]

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

Find the difference of the 2 x- intercepts using absolute value

distance = | [tex]\frac{3}{2}[/tex] - (- [tex]\frac{1}{3}[/tex] ) | = | [tex]\frac{3}{2}[/tex] + [tex]\frac{1}{3}[/tex] | = | [tex]\frac{11}{6}[/tex] | = [tex]\frac{11}{6}[/tex]

Answer:

Answer:

A- 36 inches

Step-by-step explanation:

The equation gives you 60 as a diagonal, so that means that 60 is the hypotenuse. It also gives you 48 as the length of a base.

Putting that into the Pythagorean theorem, you get...

48^2 + ?^2 = 60^2

Now, you need to solve for ?. After solving through the equation and simplifying, you're gonna get 36.

Answer:

Step-by-step explanation:

4) Angles opposite to equal sides are equal

45 + 45 + x = 180     {Angle sum property}

        90 +x = 180       {Subtract 90 from both sides}

               x = 180 - 90  

               x = 90

120 +y + y = 180        {Angle sum property}

      120 +2y = 180       {Subtract 120 from both sides

              2y =180 - 120

               2y = 60      {Divide both sides by 2}

                 y = 60/2

y = 30

5)All sides are equal. so this is a equilateral triangle.

So each angle of equilateral triangle = 60

4x = 60

x = 60/4

x = 15

y = 60 +60   {Exterior of triangle equal sum of opposite interior angles}

y = 120

6) All sides are equal. so this is a equilateral triangle.

So each angle of equilateral triangle = 60

y - 10 = 60    {add 10 to both side}

y = 60 + 10

y = 70

x + 5 = 60    {Subtract 5 from both sides}

x = 60 - 5

x = 55

Answer:

For 4 times the original recipe  Lebron needs 12 cups of cranberry juice with  8 cups of apple juice.

Step-by-step explanation:

For 5 cups of punch Lebron needs 3 cups of cranberry juice with 2 cups of apple juice.

For 4 times the original recipe  Lebron needs 3*4= 12 cups of cranberry juice with 2*4= 8 cups of apple juice.

He will get 20 cups of punch.

We multiply each ingredient of the original recipe by the factor 4 to get the required ingredients of the 4 times product as the original product.
