Answer:
-7
Step-by-step explanation:
4 + (-11)
=> {since, positive x negative = negative}
=> 4 - 11
=> -7
Answer:
7 1/3
Step-by-step explanation:
1 2/3 - ( -5 2/3)
Subtracting a negative is like adding
1 2/3 + 5 2/3
6 4/3
Simplify the fraction
6 3/3 + 1/3
7 1/3
Answer:
9/19
Step-by-step explanation:
if 20 students are boys, then the remaining students are girls. 38-20 = 18
There are 18 girl students.
18/38 can be simplified to 9/19
Answer:
The side lengths are 32 units each
Step-by-step explanation:
Given
Required
The side lengths and missing angles
Since JKMN is as square, then:
-- all sides are equal
Collect like terms
Divide by -2
Substitute in
The missing angles can't be solved without an attachment.
<em>However, if the missing angles are the angles at the edges of the square, then they measure 90 degrees each (i.e. angles at right angle)</em>
We first must find the value of angle z.
Angle z = 90° - 42°
Angle z = 48°
We now use the sine function to find y.
sin(48°) = 35/y
y = 35/sin(48°)
y = 47.0971455362
We now round off to two decimal places.
y = 47.10
I hope this helps....
