3/5 of the ride = 15 km
1/5 of the ride = 15 ÷ 3 = 5km
5/5 of the ride = 5 x 5 = 25km
Answer: the ride is 25km
Answer:
x = 2.8 units
Step-by-step explanation:
volume = width x length x height
23.52 = 1.5 x 5.6 x height
height = 23.52/(1.5 x 5.6) = 23.52/8.4 = 2.8 units
Answer:
78.5
Step-by-step explanation:
3.14*5*5=78.5
Answer:
∠a and ∠d; ∠b and ∠c
Step-by-step explanation:
The two triangles as similar triangles and the scale factor is 2 : 1
The sides measuring 6 and 3 are corresponding sides
The sides measeuring 8 and 4 are ocrreposnding sides
⇒ ∠a and ∠d are corresponding angles
The sides measuring 8 and 4 are corresponding sides
The sides measeuring 4 and 2 are ocrreposnding sides
⇒ ∠b and ∠c are corresponding angles
Answer:
⇒ The given quadratic equation is x2−kx+9=0, comparing it with ax2+bx+c=0
∴ We get, a=1b=−k,c=9
⇒ It is given that roots are real and distinct.
∴ b2−4ac>0
⇒ (−k)2−4(1)(9)>0
⇒ k2−36>0
⇒ k2>36
⇒ k>6 or k<−6
∴ We can see values of k given in question are correct.
