Step-by-step explanation:
AC is not the hypotenuse. AB is the hypotenuse because its opposite the 90 deg angle
The total cost without the discount is given by:
$
Then, to find the discounted amount, we make the following rule of three:
10 $ ------------------> 100%
x ----------------------> 20%
From here, we clear the value of x.
We have then:
Then, the cost of the Strawberries with the discount is:
$
Answer:
Kate pays for the strawberries about $ 8.
Answer:
u gotta multiple 280 with 1.17 which results 327.6
Answer:
(5,-2)
Step-by-step explanation:
9x+5y=35
2x+5y=0
Multiply the second equation by -1
-1 (2x+5y) = 0*-1
-2x-5y = 0
Add the first equation and the modified second equation
9x+5y=35
-2x-5y = 0
-------------------
7x = 35
Divide by 7
7x/7 = 35/7
x = 5
Now we need to find y
2x+5y = 0
Substituting in x
2(5) +5y = 0
10 +5y = 0
Subtract 10
10-10 +5y = -10
5y = -10
Divide by 5
5y/5 = -10/5
y = -2
(5,-2)
Answer:
When the opposite sides of the trapezoid are parallels each other and the sumatory of the inner angles is equal to 180°.
Step-by-step explanation:
The definition of a trapezoid is: a quadrilateral figure that only have two parallels sides and unequal each other. There are diferent types of trapezoids and can be classifiyed according to there inners angles. The rectangulum trapezium has two consecutive angles of 90°. The isosceles trapezium has two and two aquals angles, and the scalen trapezium has the four inner angles unequal each other.
A parallelogram is a quadrilateral figure too but a parallelogram has all his sides parallels each others. Examples of parallelograms are the recntagle, the rhomb and the romboid.
In conclusion we can say that a trapezoid is a parallelogram when the opposites sides of the tifgure are totally parallels and the sumatory of the iner angles is equal to 180°.
