You are planning a trip to Yellowstone National Park, and know that you can save money by driving
and staying with family along the way. The first leg of your journey will be 426 miles from Portland,
OR to Boise, ID where your aunt lives. After visiting with her, you will drive 388 more miles to
Yellowstone. Estimate the number of miles you will drive to get to Yellowstone National Park by
first rounding to the tens place.
Answer:
the number of miles that you would drive to go the yellowstone is 814 miles
Step-by-step explanation:
The computation of the number of miles that you would drive to go the yellowstone is shown below:
= First leg of the journey from portland + more drives to yellow stone
= 426 miles + 388 miles
= 814 miles
Hence, the number of miles that you would drive to go the yellowstone is 814 miles

The area of Jordan’s yard can be modeled by the expression 3x2 – 2x + 1. Jordan purchases additional land from his neighbors. The area of this land can be modeled by the expression 4x2 + 3x + 7. Which expression represents the new area of Jordan’s yard?
A.
x2 + 5x + 6
B.
x2 + x + 8
C.
7x2 + x + 8
D.
7x2 + 5x + 6
Answer:
7x^2 + x + 8
Step-by-step explanation:
here's your solution
=> The model of Jordan yard = 3x^2 - 2x + 1
=> The model of new yard = 4x^2 + 3x+ 7
=> now, for total area we need to add both
=> 4x^2 + 3x^2 + 3x - 2x + 7 + 1
=>7x^2 + x + 8

x = 6.156
will give brainliest if you help with this question.
Answer: (-5, 2). Please mark me brainliest
Step-by-step explanation: So we are finding the coordinates of point A first we have to mark the x-coordinate (-5) so we have to look at the horizontal line (x-coordinate) and the A is an -5 so the first part should be -5 next we have to do the vertical line (y-coordinate) and it is on the 2 so 2 so the answer is (-5,2).

Daniela fue a la florería a comprar rosas rojas para regalar a su madre el día de su cumpleaños. Si una rosa cuesta $2.550 ¿Cuánto cuesta 2 docenas?
Answer:
2 docenas cuestan $61.200.
Step-by-step explanation:
Para encontrar la respuesta, debes considerar que una docena equivale a 12 artículos, por lo cual tienes que multiplicar 12 por 2 para encontrar el número de rosas en 2 docenas:
12*2=24
Ahora, dado que sabes que una rosa cuesta $2.550 tienes que multiplicar este valor por 24 para encontrar cuanto cuestan 2 docenas:
$2.550*24=$61.200
De acuerdo a esto, la respuesta es que 2 docenas cuestan $61.200.

A car and a truck left Washington, DC traveling in opposite directions. The car
traveled 19 miles
per hour faster than the truck, and at the end of 8 hours they were
1048 miles apart. What was the average speed of each vehicle?
Answer:
The speed of the car is 75 mph.
The speed of the truck is 56 mph.
Step-by-step explanation:
Call the speed of the truck (x) miles per hour. As per the given information, the car is (19) miles per hour faster. Thus, one can form expressions to represent the speeds of the vehicles.
car = ( x + 19 ) mph
truck = ( x ) mph
Using the formula, ( (speed) * (time) = (distance) ), one can say that the speed of the car, times the time it took plus the speed of the truck times the time will equal the distance between the two vehicles:
(( car speed )( time )) + (( truck speed )( time )) = ( distance between vehicles )
Substitute,
( ( x + 19 ) ( 8 ) ) + ( ( x ) ( 8 ) ) = 1048
Simplify,
8x + 152 + 8x = 1048
16x + 152 = 1048
-152 -152
16x = 896
/16 /16
x = 56
Add (19) to find the speed of the car:
truck speed + 19
= 56 + 19
= 75
The speed of the car is 75 mph.
The speed of the truck is 56 mph.
Answer:
The truck traveled at 81
mph. The car traveled at 100
mph.
