(02.03 MC) The temperature at a mountain base camp was −2 degrees Celsius on Thursday. Friday morning, the temperature was 1 deg

aev [14]

Answer:

The temperature at the base camp Friday evening is - 6 degrees Celsius.

Step-by-step explanation:

To get the temperature at a mountain base camp on Friday evening, we must translate statement into a mathematical form:

(i) The temperature at a moutain base camp was - 2 degress Celsius on Thursday:

$T_{o} = -2\,^{\circ}C$

(ii) Friday morning, the temperature was 1 degree Celsius lower than it was on Thursday:

$\Delta T_{1} = -1\,^{\circ}C$

(iii) Friday evening, the temperature was 3 degrees Celsius lower that it was that morning:

$\Delta T_{2} = -3\,^{\circ}C$

The temperature at the base camp Friday evening is:

$T = T_{o}+\Delta T_{1}+\Delta T_{2}$

$T = -2\,^{\circ}C-1\,^{\circ}C-3\,^{\circ}C$

$T = -6\,^{\circ}C$

The temperature at the base camp Friday evening is - 6 degrees Celsius.

Which one is the correct one

kenny6666 [7]

Step-by-step explanation:

Sum of opposite angles are supplementary,

x + 60 + 3x = 180

4x + 60 = 180

4x = 180 - 60

4x = 120

x = 120 / 4

x = 30

What’s -3+4(-2) 4-2(-5) (-7+3)(4-5x2)

White raven [17]

Answer:

1. -2

2. -10

3. -8

Step-by-step explanation:

1. you add 4 to -3 which is equal to one then you multiply 1 by -2 which is -2

2. 4-2=2 then 2(-5) is equal to -10

3. -7+3=-4 and 4-5 is equal to -1 then you multiply that by 2 which is equal to -2

A scooter travels 18 miles in the same time a bike covers 8 miles. If the rate of the scooter is two miles per hour than twice t

blsea [12.9K]

ANSWER:

A scooter travels 18 miles in the same time a bike covers 8 miles.The rates of both scooter and bike are 8 miles per hour and 18 miles per hour

SOLUTION:

Given, a scooter travels 18 miles in the same time a bike covers 8 miles.

The rate of the scooter is two miles per hour than twice the rate of the bike

We need to find both rates of scooter and bike.

Let the speed of scooter be x and speed of bike be y.

And, time taken to travel be t.

Then, for scooter:

$\bold{distance = speed \times time}$

$18 = x \times t$

$t=\frac{18}{x}$ --- (1)

For bike:

$\bold{distance = speed \times time}$

$8=y \times t$

$\mathrm{t}=\frac{8}{y}$ --- (2)

Now, equate both (1) and (2)

$\frac{18}{x}=\frac{8}{y}$

On cross-multiplication we get

18y = 8x

4x – 9y = 0 ---- (3)

We also know that, rate of the scooter is two miles per hour than twice the rate of the bike.

x = 2 + 2y ---- (4)

Now substitute (4) in (3)

4(2 + 2y) – 9y = 0

8 + 8y – 9y = 0

9y – 8y = 8

y = 8.

Again substitute y value in (4)

x = 2 + 2(8) = 2 + 16

x = 18.

Hence, the rates of both scooter and bike are 8 and 18 miles per hour
