A phone shop sells iPhones and Samsung phones in a ratio of 7:5.
Last week the shop sold 42 iPhones.

How many Samsung phones did it sell?

Answers

Answer:

Step-by-step explanation:

Given the ratio 7 : 5

The 42 iPhones sold relates to the 7 part of the ratio.

Divide 42 by 7 to find the value of one part of the ratio.

42 ÷ 7 = 6 ← value of 1 part of the ratio, thus

5 parts = 5 × 6 = 30 ← number of Samsung phones sold

Answer:
They sold 30 Samsung’s

Step-by-step:explanation:
If they sold 42 iPhones then skip count 7,14,21,28,35,42 and as you can see we skipped count 6 times so then just do 5 times 6 which will give u 30

Last winter in the northeast the temperature was 5degrees Fahrenheit at midnight. It dropped 3 degrees every hour for 3hours and then rose 8 degrees every hour after that. What was the temperature at noon?

Answers

Answer:

68 [tex]^\circ F[/tex]

Step-by-step explanation:

Initial temperature in the northeast in the midnight = 5 [tex]^\circ F[/tex]

Drop for the next three hours = 3 degrees per hour.

Temperature after the 3 hours = 5 [tex]^\circ F[/tex] - 3 - 3 - 3 = - 4[tex]^\circ F[/tex]

Now, it is given that the temperature is rising 8[tex]^\circ F[/tex] every hour.

3 hours have already passed from the midnight.

Now, there are 9 more hours till noon.

So, the temperature at noon can be found by adding 8 for 9 times in the temperature after 3 hours.

Temperature at noon = - 4 + 8 + 8 .... 9 times

Temperature at noon = - 4 + 9 [tex]\times[/tex] 8 = -4 +72 = 68[tex]^\circ F[/tex]

Therefore, the answer is: 68[tex]^\circ F[/tex]

Jubal wrote the four equations below. He examined them, without solving them, to determine which equation has no solution.

7 x + 1 = 7 x+ 1. 3 x + 2 = 3 x minus 2. 4 x + 1 = 3 x + 8. negative 2 x minus 1 = negative 2 x minus 1.

Which of Jubal’s equations has no solution?
