A weather forecaster says the temperature will be about-5C “give or take” 10 degrees. What is the greatest possible temperature?
IRINA_888 [86]

The greatest possible temperature is 5^{\circ} \mathrm{C} and least possible temperature is -15^{\circ} \mathrm{C}

<u>Solution:</u>

Given that according to weather forecaster the temperature will be about -5 degree celsius given or take 10 degree”

Need to determine greatest possible temperature and least possible temperature.

Give and take in given statement means a temperature can go up by 10 degrees and can go down by 10 degrees

So greatest possible temperature will be -5^{\circ} \mathrm{C}+10^{\circ} \mathrm{C}=5^{\circ} \mathrm{C}

Least possible temperature will be -5^{\circ} \mathrm{C}-10^{\circ} \mathrm{C}=-15^{\circ} \mathrm{C}

Hence according to weather forecaster, greatest possible temperature = 5^{\circ} \mathrm{C} and least possible temperature = -15^{\circ} \mathrm{C}

PIT_PIT [208]
So we have 2 variables here: tacos and orders of nachos.

When we translate the paragraphs into equation: 28t + 27n = 114.80 \\ \\ 12t + 3n = 37.20

Now, in this situation we can make use the elimination method by converting 3n to -27n.

- 108t - 27n = - 334.8

Add both equations: 28t + 27n - 108t - 27n = 114.8 - 334.8 \\ \\ - 80t = - 220 \\ \\ t = 2.75

So we find that one taco costs $2.75.

We can plug this into any of the first two equations to find n: 12 \times 2.75 + 3n = 37.2 \\ \\ 33 + 3n = 37.2 \\ \\ 3n = 4.2 \\ \\ n = 1.4

So one order of nachos cost $1.40.

Marianna [84]

Answer: No, the equation is not accurate.

Step-by-step explanation: The proper equation is 4x + 40 = 129. This is because 16 is nowhere in the scenario, and the term before x is months, so the correct term would be 4x.

Trent is fishing from a pier.
snow_tiger [21]
To estimate the distance between the tip of his fishingrod which is above the water and the hook which is below the water, you will need to estimate the absolute values of both distances.
|53 3/4| + |12 2/3|54 + 1367 ft
Trents estimate is not reasonable because you would around both of these values up to the next whole number making it greater than 65.

What kind of slope is (6,-3)and (-4,-3)
Pavel [41]

Answer:

0

Step-by-step explanation:

Slope = y2- y1/x2 - x1

Given

x1 = 6

y1 = -3

x2 = -4

y2 = -3

Slope = -3 -(-3) /-4 - 6

= -3 + 3 /-10

= 0/10

= 0

This means that the line of the slope is horizontal
