Mateo and Logan finished 65% of their math homework. If it has 20 problems, how many problems have they done?​
frosja888 [35]

Answer:

1st question: 13 questions

2nd question: Mr.Philps will not have enough

Step-by-step explanation:

Mateo and Logan finished 65% of their math homework. If it has 20 problems, how many problems have they done?​

20 x 0.65 = 13

Mr. Philps made 1 gallon of fruit punch for his class party. If he has 27 students, and each of them will drink 1 cup, will he have enough?

1 gallon = 16 cups

27 students x 1 cup each = 27 cups

27 is greater than 16, so no, he will not have enough.

Create an Equation that represents a line that is perpendicular to a line with a slope -2?
Mademuasel [1]

(first step:

you must remember the following theorem :

Two lines whose slopes are m1 and m2, are perpendicular if and only if m1m2 = -1

(second step

you have one slope given and it  is -2 then you  substitute in the previous equation

(third step

m1*-2=-1⇒m1=-1/-2⇒m1= 1/2

it means that new slope of the equation is 1/2

(for step

with a given point and a  the slope you can build the equation that is perpendicular to a line with slope -2

the equation point- slope is

y-y1=m(x-x1)

with any given point as (2,-5) substitute it in the previous equation

[y-(-5)]=  1/2(x-2)⇒ (y+5) = 1/2x-1/4⇒y-1/2x+5+1/4⇒y-1/2x+21/4 =0

(five step

you must look for the value of x in the following equation

y-1/2x+21/4 =0

where, y = 1/2X-21/4  and this is the equation that represents a line that is perpendicular to a line with slope -2
