The temperature decreased so you would subtract the amount from the original temperature.

The answer would be:

-15 - 10 = -25

In Jamie's class, 1/5 of the students are boys. What percent of the students in Jamie’s class are boys?

Cloud [144]

Answer:

The percentage of boys students in Jamie's class is 20 %

Step-by-step explanation:

Given as :

The total number of boys in the Jamie's class = $\frac{1}{5}$ of the total student

Let the total number of student's in the class = x

So, The number of boys = $\frac{1}{5}$ × x

I.e The number of boys = $\dfrac{x}{5}$

So , in percentage the number of boys students in class = $\dfrac{\textrm Total number of boy student}{\textrm Total number of students}$ × 100

OR, % boys students = $\dfrac{\dfrac{x}{5}}{x}$ × 100

or, % boys students = $\frac{100}{5}$

∴ % boys students = 20

Hence The percentage of boys students in Jamie's class is 20 % . Answer

JKLM is a rhombus. KM is 10 and JL is 24. Find the perimeter of the rhombus.

Ahat [919]

Given that JKLM is a rhombus and the length of diagonal KM=10 na d JL=24, the perimeter will be found as follows;
the length of one side of the rhombus will be given by Pythagorean theorem, the reason being at the point the diagonals intersect, they form a perpendicular angles;
thus
c^2=a^2+b^2
hence;
c^2=5^2+12^2
c^2=144+25
c^2=169
thus;
c=sqrt169
c=13 units;
thus the perimeter of the rhombus will be:
P=L+L+L+L
P=13+13+13+13
P=52 units
