The total distance, in miles, that kara walked at the park this week is 57/20.

<h3>What is the unitary method?</h3>

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that kara walks five days each week. this week she walked 7/8 mile on monday, 3/5 mile on tuesday, 4/10 on wednesday, 1/10 mile on thursday, and 9/10 mile on friday.

Now, in order to find the total distance, in miles, that kara walked at the park this week.

kara walked on Monday = 7/8

kara walked on Tuesday = 3/5

kara walked on wednesday = 4/10

kara walked on thursday=1/10

kara walked on friday= 9/10

Now, to get the total distance in miles by adding both the miles she walked this week:

7/8 + 3/5 +4/10 + 1/10 + 9/10

35/40 + 24 / 40 + 14/10

59/40 + 14/10

114/40

57/20

Therefore, the total distance, in miles, that kara walked at the park this week is 57/20.

A water balloon is thrown out of a window 96 feet above the ground. The balloon is traveling downward at 16 feet per second init

Marysya12 [62]

Answer:

3 seconds.

Step-by-step explanation:

Since we are figuring out when the water balloon will hit the ground, y will need to be equal to 0.

0 = - 16t² - 16t + 96

Now we simply factor the trinomial to find t.

0 = -16(t² - t - 6)

0 = (t - 3)(t + 2)

t - 3 = 0 ⇒ t = 3

t + 2 = 0 ⇒ t = -2

Since we are referring to time, we need to use the positive value. Therefore, the water balloon will take 3 seconds to hit the ground.

74. A portion of a board has length x feet. The other part has

Novay_Z [31]

Step-by-step explanation:

Given that,

Length of the one portion of the board = x feet
Length of the another portion = (7x – 9) feet

According to the question,

$\longrightarrow$ Total length = Sum of the length of the two pieces

$\longrightarrow$ Total length = {x + (7x – 9)} feet

$\longrightarrow$ Total length = {x + 7x – 9} feet

$\longrightarrow$ <u>Total length = (8x – 9) feet</u>

Therefore, the total length of the board as a simplified expression in x is (8x – 9) feet.

La dirección del Colegio Montes y los padres de familia están organizando un viaje cultural a Guanajuato para los alumnos de seg

notsponge [240]

Answer:

x + y = 47 (eqn 1)

x + 2y = 79 (eqn 2)

Solving the simultaneous equation,

The hotel has 15 single rooms and 32 double rooms.

Step-by-step explanation:

English Translation

The management of Colegio Montes and the parents are organizing a cultural trip to Guanajuato for second grade students and their teachers. Students will sleep in double rooms and teachers in singles. The hotel has double rooms (2 beds) and single rooms (1 bed), totaling 47 rooms and 79 beds. To confirm if they can be accommodated, they want to know how many rooms there are of each type. If "x" denotes single rooms and "y" denotes double rooms, Write the system of equations that represents the situation: Equation that represents the number of rooms (1) Equation that represents the number of beds (2)

Solution

The number of single rooms = x

The number of double rooms = y

The number of beds in single rooms = x

The number of beds in double rooms = 2y

Total number of rooms = 47

Total number of beds = 79

Sum of single and double rooms = Total number of rooms

x + y = 47 (eqn 1)

Sum of the beds in the single rooms and the beds in the double rooms = Total number of beds

x + 2y = 79 (eqn 2)

Writing the equations together

x + y = 47 (eqn 1)

x + 2y = 79 (eqn 2)

Solving the equations simultaneously,

x = 15, y = 32

Hence, the hotel has 15 single rooms and 32 double rooms.

Hope this Helps!!!
