Answer:

The answer is 1

Step-by-step explanation:

Start by solving the division part of the equation. In order to do that, you have to flip the fraction (reciprocal) and switch from division to multiplication, thus getting 3 x 3 = 9. Now you have 9 – 9 + 1, and from there you can simply work from left to right and get your final answer: 1.

To divide by a fraction, multiply by the reciprocal of that fraction

9-3x3+1

Multiply the numbers

9-9+1

Since two opposites add up to zero, remove them from the expression

sweet [91]

Answer:

Mr. devito needs to buy 40 packs

Step-by-step explanation:

Given:

Total number of fourth grade students = 118

The number of pencils in one pack = 6

The number pencil each student gets =2

To find:

The number of packs of pencils that is to be bought = ?

Solution:

To give all the 118 fourth grade students each 2 pencils , the total number of pencils needed will be

= > $118 \times 2$

=> 236 Pencils

We know that a pack contains 6 pencils, so the number of pack that has to be bought , in order to have 236 pencils will be

=> $\frac{ \text{total number of pencils}}{\text{ number of pencils per pack }}$

On substituting the values

=> $\frac{236}{6}$

=> 39.33

=> 40

How do you solve this type of problem?<br> Thanks!

Stolb23 [73]

We know that the total is 180 degrees of the lines.

To find x:
(5x+20)+(4x-11) = 180
x=19

To find y, input the value of x into the equation 4x-11 since this equation is equal to 2y+19
4(19)-11 = 65
2y+19 = 65
y=23

RS 40 as a percent of RS 25 with step by step solution

gregori [183]

Answer:

Step-by-step explanation:

Solution for What is 25 percent of 40:

25 percent * 40 =

(25:100)* 40 =

(25* 40):100 =

1000:100 = 10

Now we have: 25 percent of 40 = 10

Question: What is 25 percent of 40?

Percentage solution with steps:

Step 1: Our output value is 40.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$40=100\%$.

Step 4: Similarly, $x=25\%$.

Step 5: This results in a pair of simple equations:

$40=100\%(1)$.

$x=25\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{40}{x}=\frac{100\%}{25\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{40}=\frac{25}{100}$

$\Rightarrow x=10$

Therefore, $25\%$ of $40$ is $10$

If the initial population is 3100 [that is, p(0)equals 3.1], what can be said about the limiting population ModifyingBelow li

jarptica [38.1K]

Answer:

Step-by-step explanation:

Given that initial population is 3100

The population is decreasing continuously which means the population at any time t can be represented by the funciton

$P = P_0 e^{-rt}$

where t = time and r = rate

The population is continuously decreasing at the rate of r% per unit of time.

When t becomes very large,

we get limit would be P0 (0) =0

The population will decrease and almost tend to 0 as time advances.

There is no chance for further decrease as population cannot be negative

So limiting population is 0.
