Asanji left the science museum and drove toward the lake at an average speed of 45 km/h. Sometime later Huong left driving in th

Cloud [144]

Answer:

Asanji drove for $5$ hours before Huong caught up

Step-by-step explanation:

Let the time for which Asanji drove alone is "X" hours

Asanji and Huong met after three hours of driving of Huong.

Total time for which Asanji drove $= X+3$ hours

Thus, distance travelled by Asanji in $X+3$ hours is equal to distance travelled by Huong in $3$ hours

$45 ( X+3) = 75 (3)\\$

On solving the above equation, we get -

$45 X + (45 *3) = 75 *3\\45 X = (75-45)*3\\45 X = 30 *3 \\X = \frac{30 *3}{45} \\X = 2$

Asanji drove for $3 + 2 = 5$ hours before Huong caught up

Through: (-3,-5), perp. to y=-1/3x+2

lara [203]

Y = -1/3x + 2.....the slope here is -1/3. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, flip the slope and change the sign. So the slope is -1/3.....flip it and it becomes - 3/1....change the sign and it becomes 3/1 or just 3. So ur perpendicular line will have a slope of 3.

y = mx + b
slope(m) = 3
(-3,-5)....x = -3 and y = -5
now sub into the formula and find b, the y int
-5 = 3(-3) + b
-5 = -9 + b
-5 + 9 = b
4 = b
so ur perpendicular equation is : y = 3x + 4 <===

The temperature on Wednesday evening was -5 Fahrenheit. The temperature decreased another 8 degrees throughout the night. What w

katovenus [111]

Answer:

The Temperature on Thursday morning will be -13° Fahrenheit.

Step-by-step explanation:

Given:

Temperature on Wednesday evening = -5 Fahrenheit

Temperature decreased Throughout the night = 8 degrees

We need to find the Temperature on Thursday morning.

Now we know that;

The temperature decreased means the temperature went more below the current temperature.

So To calculate Temperature on Thursday morning we will Subtract the temperature which got decreased by the temperature noted on Wednesday evening.

framing in equation form we get;

Temperature on Thursday morning = $-5-8 =-13\°\ Fahrenheit$

Hence The Temperature on Thursday morning will be -13° Fahrenheit.
