Answer:
Point B
Step-by-step explanation:
Lines given:
- y= 2/5x - 1/2
- y= -1/3x +2/3
x coordinate of intersection of given lines is:
- 2/5x - 1/2= -1/3x+2/3
- 2/5x+1/3x= 2/3 +1/2
- 6/15x+5/15x= 4/6+3/6
- 11/15x=7/6
- x= 7*15/11*6
- x= 35/22
For this value of x, the value of y is:
- y= 2/5*35/22 - 1/2
- y=14/22- 1/2
- y= 3/22
As per graph point (35/22, 3/22) is point B
Answer:
30
Step-by-step explanation:
s_{n}=\frac{a+l}{2}=n
first term=a
last term=l
number of terms=n
1485=\frac{6+93}{2}n
99 n=1485×2=2970
n=2970/99=270/9=30
number of terms=30
Answer:
A option
Step-by-step explanation:
ΔMNO: ∠M=79°, ∠O=22°, then ∠N=180°-79°-22°=79°.
ΔGHK: ∠G=∠H=79°, then ∠K=180°-79°-79°=22°.
ΔPQR: ∠R=20°, ∠Q=79°, then ∠P=180°-79°-20°=81°.
ΔDEF: ∠E=82°, ∠F=22°, then ∠D=180°-82°-22°=76°.
Similar triangles have congruent angles, then
ΔMNO and ΔGHK are similar.
Answer:
100m race
Step-by-step explanation:
because 10.4 x 4 because 100m and 400m right 10.4x4=41.6 and 43.9 so obviously the 100m race is faster.
