Given:
There are 4/5 as many students who do not wear glasses as those who do.
60 students wear glasses.

Find the total number of students in the grade.

Calculate 60 * 4/5 = (60 * 4)/5 = 240 / 5 = 48 students who do not wear glasses.

Total students = 60 w/ glasses + 48 w/o glasses = 108 students.

108 students

Further explanation

Given:

In the fifth grade at Lenape Elementary School,

  • there are ⁴/₅ as many students who do not wear glasses as those who do wear glasses;
  • there are 60 students who wear glasses.

Question:

How many students are in the grade?

The Process:

Create a model representing the students who wear glasses.

\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} = 60

Next, build a model for the students who do not wear glasses. From the information above, the number of students without glasses equals ⁴/₅ of those with glasses.

\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} =?

Now compute how many students do not wear glasses.

\boxed{ \ = \frac{4}{5} \times 60 \ }

We canceled 5 with 60.

\boxed{ \ = 4 \times 12 \ }

\boxed{\boxed{ \ 48 \ }}

Finally, add the counts of students who wear glasses and who do not to obtain the total number in the grade.

\boxed{\boxed{ \ 60 + 48 = 108 \ students \ }}

tester [12383]

Response:

2/9 = 0.22

Clarification:

There are two ways to select the first number that is odd and less than 5: 1 and 3.

For each of these, the second number drawn can be any of the values from 1 to 9, giving us a total of 18 options.

Out of these, the only pairs that result in a sum less than 5 are (1,1), (1,2), (1,3), and (3,1). Thus we have 4 combinations from the total of 18:

4/18 = 2/9 = 0.22

Let P be a point not on the line L that passes through the points Q and R. The distance d from the point P to the line L is d =
AnnZ [12381]

Answer:

The distance from the point (0,1,1) to the specified line is zero.

Step-by-step explanation:

Considering the parametric equations of the line,

x=2t, y=5-2t, z=1+t

In order to calculate the distance from (0,1,1), we must remove t from the equations above, such that

y=5-2t=5-x\implies x+y=5=4+1=4+z-t=4+z-\frac{1}{2}x

\implies 3x+2y-2z-8=0\hfill (1)

whose direction ratios are (l,m,n)=(3,2,-2) and the distance from point (a,b,c)=(0,1,1) is defined as

\frac{al+bm+cn}{\sqrt{l62+m^2+n^2}}=\frac{(3\times 0)+(2\times 1)+(-2)(1)}{\sqrt{3^2+2^2+(-2)^2}}=\frac{0+2-2}{\sqrt{17}}=0

The distance between the point (0,1,1) and (1) amounts to zero. Therefore, the point (0,1,1) is located on the line (1).

A student is deriving the quadratic formula. Her first two steps are shown. Step 1: –c = ax2 + bx Step 2: -c = a[x^2+b/ax] Which
Svet_ta [12734]

The options presented are:

(1) division property of equality

(2) factoring the binomial

(3) completing the square

(4) subtraction property of equality

Response: (2) factoring the binomial

Step 1: -c = ax^2 + bx

Step 2:-c = a[x^2+\frac{b}{a} x]

In step 2, 'a' is extracted from ax^2 + bx. Upon factoring out 'a', we divide all terms by 'a', resulting in a[x^2+\frac{b}{a} x].

Step 2 involves the binomial factorization process.
