Answer:

The first step is to Multiply The next step is to Divide.

Step-by-step explanation:

Ok so if you were wondering what to do on the box that says this

Move Decimal
Divide
Multiply
Subtract
Bring down

Like my self on this. The answer is simple. Just click them in order from first to last. Wow such detective work I did. I know, it's not much but I was kind of confused on this as well so you might be too. So to explain the actual answer here we go. Now in order to solve these types of problems you have to use a technique called PEMDAS which stands for.

Parenthisis
Exponent
Multiply
Divide
Add Subtract

I know I spelled the first one wrong but its 2 am and I'm doing school for you. Now we have to take into account, does this have any parentheses. This certain problem does not. Now we have to look to see if this problem has exponents, yes it does. As stated in the answer box on the lesson itself. So know we have to take that into concideration(spelled wrong but I dont care this is math class)Now we multiply by a power of 10, so the divisor is a whole number. The next step is to divide by figuring out how many times 25 goes into 105. I know that was copied from the question but oh well. So this was the explanation, I know I didn't solve the whole problem but I had no need to, it wasn't in the question.

ΔABC is a right triangle. Prove: a2 + b2 = c2 Right triangle BCA with sides of length a, b, and c. Perpendicular CD forms right

777dan777 [17]

Answer: Pythagorean Theorem Pieces of Right Triangles is not a justification for the proof.

Explanation : Here, $\triangle ABC$ is a right triangle with sides a, b and c. Perpendicular CD forms right triangles BDC and CDA.

CD measures h units, BD measures y units, DA measures x units.

Draw an altitude from point C to Line segment AB Let segment BC = a segment CA = b, segment AB = c, segment CD = h, segment DB = y, segment AD = x,

y + x = c

a/c=y/a( Similarity theorem in triangles ABC and DBC )

$a^2 = cy$ ------(1) (Cross Product Property)

Similarly, $b^2 = cx$ (Similarity theorem in triangles ABC and ADC)---------(2)

$a^2 + b^2 = cy + cx$ (after adding equation (1) and (2) )

$a^2 + b^2 = c(y + x)$ ( By additional property of equality)

$a^2 + b^2 = c^2$ . ( because y + x=c)

Thus, it has been proved that except Pythagorean Theorem Pieces of Right Triangles we use all other properties.

At Pizza Perfect, Ron and Harold make pizza crusts. When they work separately Ron finishes the job of making 100 crusts 1.2 hour

Arada [10]

Answer: Ron take approximately 4.2 hours to make 100 crusts alone.

Step-by-step explanation:

Since we have given that

Number of hours taken by Ron before Harold = 1.2 hours

Number of hours taken by Ron and Harold together = 1.8 hours

We need to find the number of hours taken by Ron alone i.e. 'x'.

Let number of hours taken by Harold alone be '1.2-x'.

Let work done by Ron alone = $\dfrac{1}{x}$

Work done by Harold = $\dfrac{1}{x-1.2}$

According to question, we get that

$\dfrac{1}{x}+\dfrac{1}{x-1.2}=\dfrac{1}{1.8}\\\\\dfrac{x-1.2+x}{x(x-1.2)}=\dfrac{1}{1.8}\\\\\dfrac{2x-1.2}{x^2-1.2x}=\dfrac{1}{1.8}\\\\3.6x-2.16=x^2-1.2x\\\\x^2-1.2x-3.6x+2.16=0\\\\x^2-4.8x+2.16=0\\\\x=0.5,4.2$

x-1.2 does not satisfied with x = 0.5 so, x = 4.2

Hence, Ron take approximately 4.2 hours to make 100 crusts alone.

Abe and Amil rode in a bike-a-thon. Abe rode for 77 minutes at a faster rate per mile than Amil. Find Amil's unit rate. Then exp

sp2606 [1]

Step-by-step explanation:
If Abe rode for 77mins
Let ta represent Amil time and tb represent Abe time.
Then tb=77mins
The rate if amil is faster than able
Let the speed of mail be Va and that of Abel be Vb
Therefore Va>Vb
Velocity = distance / time
Amil rate Va=d/ta
If Amil rode 15miles
Da = 15miles
ta= 55mins
Since they are on the same track then the rate of Amil is
Va=Da/ta
Va= 15/55
Va= 0.273miles/minutes
Since they are on the same track they will have the same speed Da.
Vb= 15/77
Vb= 0.195miles/minutes

contractor wishes to build 9 houses, each different in design. In how many ways can he place these houses on a street if 6 lots

Tju [1.3M]

The houses can be placed in 362,880 ways.

Step-by-step explanation:

The 9 houses are each in different design.

The each lot can place any of the 9 houses.

The 1st lot can place anyone house of all the 9 houses.
The 2nd lot can place one of remaining 8 houses.
The 3rd lot can place one of remaining 7 houses.

Similarly, the process gets repeated until the last house is placed on a lot.

From the above steps, it can be determined that :

The number of ways to place the 9 houses in 9 lots = 9!

⇒ 9×8×7×6×5×4×3×2×1

⇒ 362880 ways.

Therefore, the houses can be placed in 362880 ways.
