Answer:
2 metre= 1millimetre
Step-by-step explanation:
From the measurement of the house The front patio, is 14 meters wide in real life, is 7 millimeters wide in the drawing
Real life= 14 meters
Drawing= 7 millimeters,
The scale he used is 2 metre= 1millimetre
Which means he magnify the drawing by scale of 2 metre to get the real life structure.
✓Let us clarify it
14 meters = 7 millimeters
2 metre= x millimeter
If we cross multiply
7 millimeters× 2 metre= 14 metre × X millimeters
Make X subject of the formula we have
X= 1millimetres
Answer:
C. (x + 4)(x + 5).
Step-by-step explanation:
We need 2 numbers whose product is + 20 and whose sum is + 9.
They are + 5 and + 4 , so
x2 + 9x +20
= (x + 4)(x + 5).
Answer:
a.
R-------8/38--------RR
R------9/39--------B-------13/38-------RB
G------17/38--------RG
R-------9/38--------BR
B--------13/39------B-------12/38-------BB
G-------17/38-------BG
R-----9/38--------GR
G---------17/39-------B------13/38-------GB
G------16/38-------GG
b).
- 9 ways
- ways you can select 1 blue are; RB,BR,BG,GB
RB=9/39 × 13/38=3/38
BR= 13/39 × 9/38 =3/38
BG= 13/39 × 17/38=17/114
GB= 17/39 × 13/38=17/114
=3/38 +3/38+17/114+ 17/114 =26/57
- Probability of selecting 2 red markers= RR = 9/39 × 8/38 =12/247
- Probability of selecting a green marker and then a red marker= GR= 17/39×9/38 =51/494
24% = 24/100 = 12/50 = 6/25
24% is 6/25 fraction of world's energy.
