how many legs do 10 people have? if two people dont have legs. one person has 3 legs and one person has one leg. and mary has a
Ganezh [65]
So here is the answer. Normally, 10 people have 20 legs since each person has 2 legs each. But given the scenario that two people don't have legs, this would mean 20 minus 4, is 16 legs. Then one person has 3 legs, 16 plus 3 and it is 19. And then, another person has one leg, 19 plus 1 is 20. Therefore, the total legs would still be 20. Hope this helps. The dog does not count.

kolbaska11 [484]

Answer:

You can proceed as follows:

Step-by-step explanation:

First solve the quadratic inequality x^{2}-5x+4\leq 0. To do that, factorize, then we have that (x-4)(x-1)\leq 0. This implies that

x-1\leq 0\, \text{and}\, x-4\geq 0

or

x-1 \geq 0\, \text{and}\, x-4\leq 0

In the first case the solution is the empty set \emptyset. In the second case the solution is the interval 1\leq x \leq 4. Now we have that

A=[1,4]

B=(3,5)

C=(3,4].

To show that A\cap B\subseteq C consider x\in A\cap B. Then 1\leq x \leq 4\, \text{and}\, 1, this implies that 3, then x\in C. Now, to show that C\subseteq A\cap B consider x\in C, then 3, then 1\leq x \leq 4\, \text{and}\, 3, then x\in [1,4] \, \text{and}\, x\in (3,5), this implies that x\in A\cap B.

In 2000 the number of students enrolled at Arlington County day school was 823 students in 2010 the population was approximately
RoseWind [281]

Answer:

enrollment decreases by 14.34%.

Step-by-step explanation:

Given that number of students enrolled in 2000 = 823

Given that number of students enrolled in 2010 = 705

705 is less than 823 so that means number of students enrollment is decreasing.


Decrease = 823-705 = 118

Percent decrease is given by formula:

Percent =\frac{part}{whole}\cdot100 =\frac{118}{823}\cdot100= 14.3377885784

which is approx 14.34%.

Hence final answer is that enrollment decreases by 14.34%

Jennifer has a beginning balance of $4,750 in her Checking account. After depositing a paycheck (p), she writes a check (c), and
Zepler [3.9K]

Answer:

An Algebraic Expression that models the situation is 4750+p-c-d+r

Step-by-step explanation:

Beginning balance of Jennifer=$4750

Now she deposits a paycheck = p

So, New balance = 4750+p

Now she writes a check = c

Remaining balance = 4750+p-c

Now she writes a check = d

Remaining balance = 4750+p-c-d

Now refunded some money (r) for returning a pair of shoes she bought.

New balance = 4750+p-c-d+r

Hence  an Algebraic Expression that models the situation is 4750+p-c-d+r

The perimeter of the triangle below is 6a+2b-5 units. write an expression to represent the length in units, of the missing side
ANTONII [103]

Answer:

3a + 5b - 2

Step-by-step explanation:

The perimeter is the sum of all 3 sides of the triangle.

To find the missing side (x ) sum the 2 known sides and subtract from the perimeter.

x = 6a + 2b - 5 - (2a + 6b - 6 + a - 9b + 3 ) ← simplify parenthesis

  = 6a + 2b - 5 - (3a - 3b - 3 ) ← distribute by - 1

  = 6a + 2b - 5 - 3a + 3b + 3 ← collect like terms

  = 3a + 5b - 2 ← length of missing side
