**Answer:**

3 divide 7 is **0.4285714285714286 **but 7 divide 3 is 2.33 (Never ending)

Answer:

It’s a decimal, (0.42857142857)

Step-by-step explanation:

solve the following quadratic equation

2×2-x=21

[tex]2x^2-x=21\\\\\implies 2x^2 -x -21 =0\\\\\text{Apply quadratic formula},~ x = \dfrac{-b \pm \sqrt{b^2 -4ac}}{2a}\\\\\text{In this case,}~ a =2 , b =-1, c =-21}\\\\\implies x = \dfrac{-(-1) \pm \sqrt{(-1)^2 - 4\cdot 2 \cdot (-21)}}{2(2)}\\\\\implies x =\dfrac{1 \pm \sqrt{169}}{4}\\\\\\\implies x = \dfrac{ 1 \pm 13}4\\\\\\\text{Hence,}\\\\x =\dfrac{1+13}4 = \dfrac{14}4 = \dfrac 72\\\\\text{or}\\\\x =\dfrac{1-13}4 = -\dfrac{12}4 =-3[/tex]

**Answer:**

x1=7/4, x2=-3

**Step-by-step explanation:**

[tex]2x^{2} - x - 21 = 0\\x1,2 = (1±\sqrt{-168-1})/4\\x1,2 = (1±13)/4\\x1 = 14/4 -> x1 = 7/2\\x2 = -12/4 -> x2 = -3[/tex]

The cost of paving a square room at the rate of RS.15 per m2 is Rs.1500. What is the Area and the Perimeter of the room?

hope it helps you...................

....

..

The area of the room is equal to 100 m² and **perimeter **is 40m

The area is the **space **covered by the object. It is the region occupied by any shape. While measuring the area of a **square**, we consider only the length of its side. All sides of a **square **are equal; hence, its area is equal to the **square **of the side and the perimeter of a square = 4 × side units.

Given here: Unit rate of **painting **per meter square=15 and it cost 1500 in total

Thus **Area **= 1500/15

=100 m²

Then a²=100 and a=10

∴Perimeter of the **square **room is = 4×10

=40 m

Hence, The area of the room is equal to 100 m² and **perimeter **is 40m

Graph the line that represents a proportional relationship between d and t with the property that an increase of 3 units in t corresponds to an increase of 8 units in d. What is the unit rate of change of d with respect to t? (That is, a change of 1 unit in t will correspond to a change of how many units in d?) The unit rate of change is Graph the relationship. The unit rate of change is _____

**Answer:**

Draw a straight line through these two points (0, 0) and (1, 3).

**Step-by-step explanation:**

"Proportional relationship" implies line or curve that goes through the origin; there is no "y-intercept" in this case.

Plot a dot at (0, 0). Next, move your pencil point 1 unit to the right (you'll end up at (1, 0), and then move it from there up to (1, 3). Draw a straight line through these two points (0, 0) and (1, 3).

Work Shown:

(3 mm)/(17 m) = (x mm)/(55 m)

Solve for x.

2x−4=6−3x

A: x= -0.4

B: x= 2

C: x= -2

D: x= 0.4

**Answer:**

x = 2

**Step-by-step explanation:**

First, let's write out our equation:

[tex]2x-4=6-3x[/tex]

I want to isolate x on one side, so first, I'll add 4 to both sides to remove the -4 from next to 2x:

[tex]2x-4+4=6-3x+4\\2x=-3x + 10[/tex]

Notice that I combined like terms with the -4 and 4 (to get 0) and the 6 and 4 on the right side (to get 10). Next, I'll add 3x to both sides:

[tex]2x + 3x = -3x + 3x + 10[/tex]

And then I'll add like terms:

[tex]5x=10[/tex]

Now, all we have to do is divide both sides by 5:

[tex]5x/5=10/5\\x=2[/tex]

And there's our answer. Hopefully that's helpful! :)

Laura just became a personal trainer and is finalizing her pricing plans. One plan is to charge

$55 for the initial consultation and then $41 per session. Another plan is to charge $50 for the

consultation and $46 per session. Laura realizes that the two plans have the same cost for a

certain number of sessions. How many sessions is that? What is that cost?

Using **algebraic equations:**

the number of sessions that will give same cost for both plans is:** 1**

the cost is: **$96**

Translate the situation into **algebraic equations.**

**Equation ***for total cost of the first plan:*

y = 41x + 55

*Equation **for the total cost of the second plan:*

y = 46x + 50

To find the number of sessions that would yield same cost for both plans, make both **equations **equal to each other and solve for x.

41x + 55 = 46x + 50

Combine like terms together41x - 46x = - 55 + 50

-5x = -5

x = 1

For a session, both plans will yield the same cost.

*The cost 1 session will yield for both:*

41x + 55 = 46x + 50

Plug in the value of x41(1) + 55 = 46(1) + 50

96 = 96

Therefore, using **algebraic equations:**

the number of sessions that will give same cost for both plans is: 1

the cost is: $96

wahts the gcf and lcm of 18 and 30

Hey there. So first, to work out the LCM, we need to find the multiples of 18 and 30. We’ll start with 18, and we’ll stop at a reasonable number.

18, 36, 54, 72, 90.

30, 60, 90, 120.

Already we notice that 90 is the smallest multiple that is evident in both numbers. So 90 is your LCM.

Now for the GCF, we want to begin by creating a factor tree for 18 and 30. I found one on the internet so it’s easier to view.

When finding the GCF, you want to circle all the prime numbers you have, so in this case, for 18, we have 2 x 3 x 3. They’re all prime.

For 30, we have 2 x 3 x 5. They’re all prime.

If we now circle the numbers that are common in both so we have (2) in 18 and 30, and we have (3) in 18 and 30. We are left with 5 and 3, ignore them for now. Because we managed to circle 2 and 3, if we multiply them together, we get 6. So the GCF of 18 and 30 is 6. And the LCM of 18 and 30 is 90.

Sorry if this sounds confusing, i tried my best.

if a baseball team has lost 50 matches out of the 120 matches played in total, find out their winning percentage?

To find the amount of matches won:

120 – 50 = 70

So the baseball team has won 70 matches.

To convert this to a percentage:

(Matches won / Total matches ) x 100

(70/120) x 100 = 58.3% (rounded to 1 decimal place)

120 – 50 = 70

So the baseball team has won 70 matches.

To convert this to a percentage:

(Matches won / Total matches ) x 100

(70/120) x 100 = 58.3% (rounded to 1 decimal place)

The **percentage **is the indicating **hundredth **thus the percentage of **winning **is 58.33%.

The percentage is also called the indicating hundredths. Thus, 2% is two-**hundredth**, which means 2%=2/100=0.02.

The percentage is just like the **amount **of that value but between 1 to 100 and it is very **useful **to **predict **for example if you say 678 then we have to know about the full number also but if you say 80% then it **becomes clear**.

As per the given,

Total matches = 120

**Number **of **lost **matches = 50

Number of winning match = 120 - 50 = 70

**Winning percentage **= (70/120) x 100 = 58.33%

Hence "The **percentage **is the indicating **hundredth **thus the percentage of **winning **is 58.33%".
