Answer: 1
Step-by-step explanation:
Let the number be p
75% of P= 3/4
75/100 of P = 3/4
0.75P =3/4
Cross multiply
0.75p×4=3
0.3p=3
P=3/0.3
P= 1
Therefore 75% of 1 = 3/4
It's 2.5 bc it goes up by 2.5 everytime
Answer:
Step-by-step explanation:
- Mass = Density*Volume
- V = m/d
- V = 378.24/2.76 = 137.04 cm³ (rounded)
The 38th term in the sequence is -51
Answer:
W=4 l=16
Step-by-step explanation:
Let w = width
Let l = length
Since the length is 4 times the width, l=4w
Perimeter of rectangle = 2l + 2w
= 2(4w)+2w
=10w
The perimeter of the rectangle =40, so
40=10w and w=4
Plug w into the length equation : l=4w=4(4)=16
