Mr. Garcia's fourth grade class has 35 minutes to eat lunch every day. If their lunch begins at 11:15 a.m., at what time will their lunch end?

Answers

in this problem you can look at only the minutes. in 11:15, 11 can be considered 11 hours and 15 can be considered 15 minutes. We want to add the 35 minutes to the 15 since lunch begins at 15 minutes and ends 35 minutes after. Therefore 15 + 35 = 50 minutes. So the answer would be 11:50.

However, if lunch had started at 11:30, then we would have used 30 minutes as the start. This answer would be 30 + 35 = 65 minutes. But there is no time of 11:65. In this case since there are 60 minutes in an hour, you may subtract 60 from 65. Theb60 minutes we subtract will give us 1 hour instead and we can then add that to the 11 hours.
So
65 - 60 = 5 minutes
11 + 1 = 12 hours

Putting the 2 answers together is 12 hours and 5 minutes or 12:05
11:50

Let's take away the 11 hours. 15 plus 35 equals 50. So the answer is 11:50.

Answer:

x = 8, perimeter of triangle = 22 units

Step-by-step explanation:

the perimeter is the sum of the sides of the triangle , that is

x + x + 2 + x - 4 ( collect like terms)

= 3x - 2

the perimeter of a rectangle is calculated as

2 ( length + breadth )

= 2(x + 3) ← distribute parenthesis by 2

= 2x + 6

equate the 2 expressions for perimeter

3x - 2 = 2x + 6 ( subtract 2x from both sides )

3x - 2x - 2 = 2x - 2x + 6 ( simplify both sides )

x - 2 = 6 ( add 2 to both sides )

x - 2 + 2 = 6 + 2 ( simplify both sides )

x = 8

The perimeter of triangle is then

= 3x - 2

= 3(8) - 2

24 - 2

= 22 units

Which of the following is the reciprocal of x2 – 2x – 8?

Answers

Hi again

x² - 2x - 8
Factor
= (x + 2)(x -4)
Answer : A is the correct option.


If you wanna check if A is the right answer, I will solve it for you and it will you give you the exact answer which will be x² - 2x - 8
(x+2)(x-4)
Distribute
(x)(x) + (x)(-4)+(2)(x)+(2)(-4)
= x² - 4x + 2x - 8
= x² - 2x - 8
Here it is, we find the exam answer.

Thus, (x+2)(x-4) is the reciprocal of x² -2x - 8

8x-9y+16x+12y

How do I solve this equation

Answers

to solve this equation go to www.tigeralgebra.com
combine like terms (x's go with x's and y's go with y's) take the sign in from of the value and combine 8x+16x =24x  and -9y+12y=3y (combine only works if the variables have the same  exponent ( u can combine x and x(because they have an understood exponent of 1)  but not x and x^3)

There are 32 students in a play. The ratio of girls to all students on the play is 5 : 8. How many girls are in the play

Answers

There are 20 girls in the play.

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

Given that;

There are 32 students in a play.

And, The ratio of girls to all students on the play is 5 : 8.

Now,

Since, The ratio of girls to all students on the play is 5 : 8.

Hence, Number of girls = 5x

And, Number of students = 8x

Here, Number of all students = 32

So, We get;

⇒ 8x = 32

⇒ x = 4

Thus, Number of girls = 5x

                                  = 5 × 4

                                  = 20

Hence, Number of girls = 20
