Answer:
The best deal is the middle one.
Step-by-step explanation:
35.95 with a 20% discount.
You can do this the straight forward way. Take 20% 35.95
20/100 * 35.95 = 7.19
Now subtract this from 35.95
35.95 - 7.19 = 28.76
15/100 * 29.75 = 4.46
29.75 - 4.46 = 25.28
25% * 38.49 = 9.62
38.49 - 9.62 = 28.86
Answer:
Step-by-step explanation:
in a right angled triangle angles given are 45,90
Then third angle is also 45 °
as two angles are 45° each.
Then sides are also equal.
Let the equal sides be each =x
then hypotenuse=√(x²+x²)=√(2x²)=x√2
sin 45°=x/(x√2)=1/√2
The related multiplication fact to 3 x 5 = 15 is 4 x 3 = 12
<h3>Multiplication Facts</h3>
Given:
3 x 5 = 15
The expression a x b = c means that a is added to itself b times to give c
3x 5 means adding 3 in 5 places
That is:
3 x 5 = 3 + 3 + 3 + 3 + 3
A related multiplication fact is:
4 x 3 = 12
This is true because:
4 x 3 = 4 + 4 + 4 = 12

|p| = 7
p=7or p =-7
Answer:
I will assume that ABCD is a parallelogram.
1. In a parallelogram, opposite sides are congruent so 3x = 18 which means x = 6.
2. The diagonals of a parallelogram bisect each other so BE is half of BD, therefore, BD = 7.5.
3. Consecutive angles of a parallelogram are supplementary so m∠ADC = 180° - 135° = 45°.
4. Consecutive angles of parallelograms are supplementary so 2x + 10 + 135 = 180 → 2x + 145 = 180 → 2x = 35 → x = 17.5°.
5. Again, the diagonals bisect each other so -6 + 8v = 9v - 10 → v = 4.
6. DA || BC so ∠DAC and ∠ACB are (congruent) alternate interior angles, therefore, m∠DAC = 37°.
7. The area of a parallelogram is base * height; we know base = 18 and height = 21 u so area = 378 u.
