Perimeter of a triangle is 450 m and its sides are in the ratio 13 : 12 : 5. Find the area of the triangle and the altitude to the largest side.
Answer with steps .

Answer:

Sam solves 54. I hope this helps with your RSM.

Step-by-step explanation:

18x7=126

18x3= 54

126+54=180

Answer:  28x  + 15y = 131   and x + y =  7   where x is the number of Dress shirt and y is the number of T-shirt.

Step-by-step explanation:

We will represent the number of Dress shirt he bought by x and we will represent the number of T-shirt he bought by y.

We know that he spent 131 so the cost of each dress shirt plus the cost of each T-shirt has to equal  131.  Also, he bought 7 total shirts so x plus y has to equal 7.

28x  + 15y = 131  

x + y =  7

Note: it says don't solve so I didn't solve but if you want to solve use these equations.

Step-by-step explanation:

Order these numbers from largest at the top, to smallest at the bottom.

1.57x10^-4

4.5x10^3

1.3x10^1

987

We can see that:-

The exponent with highest power is the largest number.

Here, the largest number is

[tex]1.3 \times 10 ^3[/tex]

Next, is [tex]987[/tex]

Smaller than this, next is :-

[tex]1.3 \times 10^1[/tex]

A number with negative power is smaller.

So, last is

[tex]1.57 \times 10^{-4}[/tex]

Hope it helps :)

Answer: The answer is 40

Step-by-step explanation: If you use the formula to find the area of a triangle(A=Bh/2) and plug the number in like so(A=8 * 10) you would get 80 then you would divide the 80 by 2 and get 40

Answer:

0.08 which is eight hundredths

Step-by-step explanation:

0.283

The 8 in is the hundredths place, so the eight's value is 8 hundredths.

Answer:

the value of 8 is hundredths

I think but it can also be the first one

The graph shows a proportional relationship because it is a line, and each x-value is a multiple of 2.

Answer: it may be C

Step-by-step explanation:

The graph does not show a proportional relationship because the line does not go through the origin.

Answer:a=4

Step-by-step explanation:

Answer:

a = 4

Step-by-step explanation:

16 × a = 32 × 2

16a = 64

dividing both sides of the equation by 16 gives

16a/16 = 64 /16

a = 4

Answer:

80 yd^2

Step-by-step explanation:

Since the formula for squares is s^2, we can use this to set up an equation, which is

s^2=400

If we square root this, we get

s=20

The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2

Answer:

A. KE=1/2; B. KE=4; C. KE=24; D. KE=1

Step-by-step explanation:

A. KE=1/2*1*1²=1/2

B. KE=1/2*2*2²=1*4=4

C. KE=1/2*3*4²=1.5*16=24

D. KE=1/2*8*0.5²=4*0.25=1

Answer:

3/2

Step-by-step explanation:

Given y = 2x + 5, let's rewrite the equation in terms of x;

y = 2x + 5 => Bring 5 to the other side

2x = y - 5 => Divide either side by 2

x = (y - 5)/2

If we want to take the inverse, simply swap the variable's positions...

We have y = (x - 5)/2

Now let's determine f^-1(8), substituting for "y" provided y is our inverse, f^-1

f^-1(8) = (8 - 5)/2 = 3/2

Solution: 3/2

Answer:

-1/3 x 9x -1/3 x 30 + 2

-3x -10 +2

-3x - 8

Step-by-step explanation:

this is a distributive type of problem you distribute the -1/3 to the 9x and the 30 by distribute i mean multiply. if you dont know how to multiply this use the calculator but you multiply it by the 2 pairs of numbers in the parenthesis and then you just add the 2

Step-by-step explanation:

the answer is 9=3;/5

Answer: x=-2

Step-by-step explanation:

First subtract 4 from both sides

Sqrt(x+3)=1

Then square both sides

X+3=1

Then subtract 3

X=-2

Hope this helps!

Answer:

Answer:

Step-by-step explanation:

The simplest way to create a class with one one instance is to use an enum. public enum Singleton { INSTANCE } You can compare this with Steve Taylor's answer to see how much simple it is than alternatives. BTW: I would only suggest you use stateless singletons. If you want stateful singletons you are better off using dependency injection. ( You can create more than one tho )

But, the singleton class means you can create only one object for the given class. You can create a singleton class by making its constructor as private, so that you can restrict the creation of the object. Provide a static method to get instance of the object, wherein you can handle the object creation inside the class only.

Answer:

x = 4

Step-by-step explanation:

Well, while this is not a full quadratic equation, this can still be worked with, so let's get started.

Taking [tex]-24x=6x^2[/tex], we can simplify this just to make it a bit more professional, to say [tex]6x^2=-24x[/tex] (We can do this because of the Symmetric Property of Equality, which states that a=b then b=a).

Now, we can really start by dividing both sides by 6, to get [tex]x^{2} =-4x[/tex], and then divide both sides by x to get [tex]x=4[/tex].

So, the answer of this quadratic equation is x = 4.
