Answer:
120
Step-by-step explanation:
z=8 w=8
7(8)=56
8(8)=64
56+64=120
Answer:
b and E and c
Step-by-step explanation:
- A is false because some elements have the same image like 2.3 and 2.2 , 2.5 ...
- B is true because the image of an integer remains the same using the greatest integer function. So C is true
- E is true
Point P is at (50, -40). Point R is vertically above
point Q. It is at the same distance from point Q
as point P is from point Q.
Point P is the same distance from Point Qas
Point R.
Point R is at (-30, 40), 80 units from Point Q.
Answer:
Pumkins $7 and Watermelons $5
Step-by-step explanation:
let pumkins be P and watermelons be W s0
5P+20W=135 and 10P+16W=150
express first equation in terms of P
5P+20W=135
5P=135-20W (divide equation by 5)
P=27-4W
now express the second equation using the new P value
10P+16W=150
10(27-4W)+16W=150
270-40W+16W=150
120=24W
W=5
now plug in w value and solve for p
5P+20(5)=135
P=7
Cos 75 = 45 + 30
Formula: cos 45 x cos 30 - sin 45 x sin 30
Cos 45 = root 2 / 2
Cos 30 = root 3 / 2
Sin 45 = root 2 / 2
Sin 30 = 1 / 2
