Answer: Car B traveled 60 mph.
Step-by-step explanation:
A= B-15
A: (B - 15)(2 hr)=D
B: (B)(1.5)=D
Since B and A traveled the same distance you can plug in 1.5B for D.
2B - 30 = 1.5B
-1.5B +30 = -1.5B
——————+30—
2(0.5B) = 2(30)
B = 60 mph
Answer: The correct option is figure (1).
Explanation:
Reason for correct option:
The figure (1) shows the reflection across the side XY followed by reflection across the side YT.
When we reflect the triangle XYZ across the side XY we get the triangle XYT as shown in below figure.
After that we reflect the triangle XYT across the side YT and we get the triangle PYT.
Therefore, only figure 1 shows the triangle pairs can be mapped to each other using two reflections.
Reason for incorrect options:
The figure (2) shows the rotation of 180 degree along the point y.
The figure (3) shows the reflection across the side XY followed by the translation.
The figure (4) shows the reflection, followed by rotation , followed by translation.
Answer: the current value of the house is $343350
Step-by-step explanation:
The initial value of the house on the market was $315,000.
After several years the value increased by 9%. This means that the amount by which the value of the house increased over the years would be
9/100 × 315000 = 0.09 × 315000 = $28350
The current value of the house would be the sum of the previous value of the house and the increase in value. It becomes
315000 + 28350 = $343350
X=-1/3
In other way is
X=0.3,x=-3^-1
