-5*(-6)=
-27 divided by 9=
Answer:
-5*(-6) = 30
-27/9 = -3
Step-by-step explanation:
We know a negative times a negative is a positive, a positive times a positive is a positive, and a negative times a negative is a positive. This rule goes the same for division.
Using that rule -5*(-6) = 30. Which is a negative times a negative = positive.
-27/9 = -3 Which is a negative divided by positive = negative

I WILL GIVE YOU BRAINLIEST!!!!! The first side of a triangle is three times as long as the second side, and the third side is 50 cm shorter than the first side. Find all sides of the triangle if its perimeter is 370 cm. PLS HELP ME!!!!!!!
Answer:
The first side of the triangle = 180 cm
The second side of the triangle = 60 cm
The third side of the triangle =130 cm
Step-by-step explanation:
To solve this, we will follow the steps below;
First, re-write the question in a mathematical format and then solve;
let a=the first side of the triangle
b=the second side of the triangle and
c=the third side of the triangle
"The first side of a triangle is three times as long as the second side" can be re-write mathematically as:
a=3b ------------------------------------------------(1)
"the third side is 50 cm shorter than the first side" can be re-write as :
c=a-50-----------------------------------------------(2)
"perimeter is 370" can be re-write as:
a + b + c = 370 --------------------------------------(3)
from equation (2), make b subject of the formula; a= 3b
b=a/3 ------------------------------------(4)
substitute equation (2) and (4) into equation (3)
a + b + c = 370
a+[tex]\frac{a}{3}[/tex] + a-50 = 370
add 50 to both-side of the equation
a+[tex]\frac{a}{3}[/tex] + a-50 + 50= 370 + 50
a+[tex]\frac{a}{3}[/tex] + a= 420
[tex]\frac{3a + a + 3a}{3}[/tex] = 420
[tex]\frac{7a }{3}[/tex] = 420
multiply both-side of the equation by 3
[tex]\frac{7a }{3}[/tex] ×3= 420×3
7a = 1260
Divide both-side of the equation by 7
[tex]\frac{7a}{7}[/tex] = [tex]\frac{1260}{7}[/tex]
a= 180
from equation (4) b = a/3
b = 180/3 = 60
from equation (2) c= a- 50
c= 180 - 50
c= 130
a= 180 cm
b = 60 cm
c= 130 cm
Therefore,the first side of the triangle = 180 cm
the second side of the triangle = 60 cm
the third side of the triangle =130 cm

Tamanika got a raise in her hourly pay, from $15.50 to $17.36. Find the percent increase
Answer:
12%
Step-by-step explanation:
The required percent increase is 12%
Tamanika got a raise in her hourly pay, from $15.50 to $17.36
What is percentage?percentage is defined as, composition of something out of whole inbounds of 100.
since = 17.36 - 15.50/15.50 x 100
= 1.86/15.50 x 100
= 0.12 x 100
= 12
Thus the required percent increase is 12%.

A 28 and 45
B 79 and 88
C 19 and 45
D 28 and 17
Answer:
A 28 and 45
Step-by-step explanation:
So keep in mind that columns must add up to the total numbers, and rows must add up to their total numbers.
We know that what goes in the box canoeing + swimming is
x + 43 = 71.
It needs to add up to 71!
x = 71 - 43 = 28
We know that what goes in the box no swimming + no canoeing is
34 + y = 79
It needs to add up to 79.
y = 19 - 34 = 45
So the answer is A. 28 and 45.
Now, I did this with the columns, but you could easily do this with the rows and get the same result!

Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
tan x = [tex]\frac{sinx}{cosx}[/tex] , sec x = [tex]\frac{1}{cosx}[/tex] , sin²x + cos²x = 1
Consider the left side
tan²y × cos²y + [tex]\frac{1}{sec^2y}[/tex]

= sin²y + cos²y
= 1
= right side ⇒ proven
Step-by-step explanation:
[tex] (\tan^2y) (\cos^2y) +\frac{1}{\sec^2y} = 1\\
LHS
= (\tan^2y) (\cos^2y) +\frac{1}{\sec^2y} \\\\
\frac{\sin^2y}{\cos^2y}\times \cos^2 y + \cos^2 y \\\\
= \sin^2y + \cos^2 y \\\\

A garden measuring 12 meters by 6 meters is going to have a walkway constructed all around the perimeter, increasing the total area to 160 square meters. What will be the width of the pathway? (The pathway will be the same width around the entire garden).
Pls Show Work
Answer:
Width of Pathway; 2 meters
Step-by-step explanation:
To determine the width of the pathway we can tell that the length of the ends ( in meters ) is distributed among the two other ends of the garden so that the width ⇒
Increase length on one side * 2, if increased length / width ⇒ x, 2x
From this we can formulate an equation based on the lengths of the garden, as the increased lengths represents the side lengths of the total area ( walkway + garden );
( 12 + 2x )( 6 + 2x ) = 160 ⇒ Expand,
72 + 36x + 4x^2 = 160 ⇒ Subtract 160 on either side,
4x^2 + 36x - 88 = 0 ⇒ Factor,
4 * ( x - 2 ) * ( x + 11 ) = 0 ⇒ Use Zero Factor Principle,
x = 2, and x = - 11;
Now the width can only be a positive value, thus;
Solution; Width ⇒ 2 meters

Answer:
7/30
Step-by-step explanation:
First we need to find the number of girls on the Newcastle team, which is the total number of girls minus the number of girls on the other team, giving us 20-6=14. This means the number of player total is 3+7+6+14 or 30 players. There are 7 Sunderland boys so we have 7/30
