Answer:
1 3/4=7/4 since 1*4+3=7, so (90/7)/(7/4)=(90/7)(4/7)=360/49, mixed number form is 7 17/49 and in decimal form is 7.35.
Step-by-step explanation:
Answer:
Y = 26
W = 73
X = 81
Step-by-step explanation:
∠W = 3∠Y - 5
∠X = ∠W + 8 = 3∠Y - 5 + 8 = 3∠Y + 3
∠Y + ∠W + ∠X = 180
substitute in the formula
Y + (3Y - 5) + (3Y + 3) = 180
7Y -2 = 180
7Y = 182
Y = 26
W = 3(26) - 5 = 73
X = 73 + 8 = 81
Answer:
The one that is 0,-3 and 3,0
Step-by-step explanation:
Answer:
A) 15 cm B) 1292 cm^2
Step-by-step explanation:
A) height can be used by using Pythagoras theorem
Height^2+base^2=slant^2
height^2+8^2=17^2
height=15 cm
B) The amount of cardboard used can be found by calculating the area
Area=2*(area of triangle) + 3*(area of rectangles)
17*16+3*(20*17)=1292 cm^2
