I need help wit dis plz

A car drives for 1 hour 55 minutes with a constant speed of 36 km/h and then for another 1 hour 50 minutes with a constant speed

stich3 [128]

----------------------------------------
Convert hours to minutes
----------------------------------------
1 hour 55 mins = 60 + 55 = 115 mins
1 hour 50 mins = 60 + 50 = 110 mins

_____________________________________________________

----------------------------------------
Speed = 36/h
----------------------------------------
1 hour = 36 km

----------------------------------------
Rewrite 1 hour as 60 mins
----------------------------------------
60 mins = 36 km

----------------------------------------
Find 1 min
----------------------------------------
1 min = 36 ÷ 60
1 min = 0.6 km

----------------------------------------
Find 115 mins
----------------------------------------
1 min = 0.6 km
115 min = 0.6 x 115
115 min = 69km

_____________________________________________________

----------------------------------------
Speed = 72km/h
----------------------------------------
1 hour = 72 km

----------------------------------------
Write 1 hour as 60 mins
----------------------------------------
60 mins = 72 km

----------------------------------------
Find 1 min
----------------------------------------
1 min = 72 ÷ 60
1 min = 1.2 km

----------------------------------------
Find 110 min
----------------------------------------
1 min = 1.2 km
110 min = 1.2 x 110
110 min = 132 km

_____________________________________________________

----------------------------------------
Total Distance traveled:
----------------------------------------
69km + 132km = 201km

----------------------------------------
Answer: 201 km

Solve 0.252x = 41. Round your answer to the nearest hundredth

Oksana_A [137]

0.252x = 41

In Algebra, we must keep the equation balanced. What we do to one side, we must do to the other. We also need to isolate the variable x.

Since x is multiplied by 0.252, we must divide the left side by 0.252 to get rid of the 0.252. But, to keep the sides equal, we must do it to both sides.

0.252x/0.252 = 41/0.252

This leaves us with x = 162.69

Find the 6th term of the geometric sequence, given the first term and common ratio a1= 5 and r=3/2

uysha [10]

<u>Answer</u>

37.96875

<u>Explanation</u>

In geometric sequence we use the formula below to find the nth of a sequence.

Tn = ar⁽ⁿ⁻¹⁾

Where a ⇒ first term

n ⇒ the term we are looking for

T₆ = 5 × (3/2)⁶⁻¹

= 5 × (3/2)⁵

= 5 × 243/32

= 1215/32

= 37 31/32

= 37.96875

Mr. Shamir employs two part-time typists, Inna and Jim, for his typing needs. Inna charges $15 an hour and can type 6 pages an h

coldgirl [10]

Answer:

The minimum cost would be 480$ when Inna works for 8 hours and Jim works for 20 hours.

Step-by-step explanation:

We are given the following information in the question:

Charges for 1 hour for Inna = $15

Number of pages typed by Inna in 1 hour = 6

Charges for 1 hour for Jim = $18

Number of pages typed by Jim in 1 hour = 8

Let x be the number of hours Inna work and let y be the number of hours Jim work.

Total cost = $15x + 18y$

We have to minimize this cost.

Then, we can write the following inequalities:

$6x + 8y \geq 208\\x \geq 8\\y \geq 8\\$

The corner points as evaluated from graph are: (8,20) and (24,8)

C(8,20) = 480$

C(24,8) = 504$

Hence, the minimum cost would be 480$ when Inna works for 8 hours and Jim works for 20 hours.

The attached image shows the graph.

This is going to be tricky pls solve from i ready

shutvik [7]

Answer:

4/10 meters

Step-by-step explanation:

Original Length : 7/10 meters

Remaining Length after cut : 3/10 meters

amount cut off = original length - remaining length

= 7/10 - 3/10

= (7-3)/ 10

= 4/10
