Answer:
3/2
Step-by-step explanation:
Because the problem tells you that the two triangles are similar, the value of a/b would be equivalent for both triangles. The fact that they are right triangles also indicates which sides are which in case the image was not drawn to scale. A is proportional to 2.1 and b is proportional to 1.4. So a/b= 2.1/1.4. This can reduce itself to 3/2 because both are divisible by .7
Answer: D) 6.0 hours
Step-by-step explanation:
The destination is 420 mi away, and you're travelling at 70 mph. This means you travel 70 miles every hour. This leads to 420÷70, which is 6. The answer is 6 hours.
Answer:
The standard form is 2x^2-4x+5 and the vertex is (1,3)
Answer:
( x - 6 )² - 35
Step-by-step explanation:
x² - 12x + 1
→ Half the middle term and place it inside the bracket
( x - 6 )² + 1
→ Square it
( x - 6 )² - 36 + 1
→ Simplify
( x - 6 )² - 35
Answer:
Since the ray bd is bisecting the angle abc, equate 3x + 4 to 7x - 20.
Step-by-step explanation:
3x + 4 = 7x - 20
x = 6
.. Therefore, angle abc = 3x + 4 + 7x - 20
= 18 + 4 + 42 - 20
= 44
