If you have 49 questions on a test what score must you get to pass the test?

1 answer:

7 0

Well, on every test I have at a school and I believe most schools do this. You need at leasr 80% to pass. But to pass you'd most likely need 80% or 70%. But if you get an 80% you'll be sure to pass! I hope this helps you!

Can someone show me how to do this? I’m not sure how to do this

Allushta [10]

Answer: Slope means the gradient. So find the equation of the line first then graph the points on the graph.

Step-by-step explanation:

y=mx+c *We want m*

m=(y2-y1)/(x2-x1)

m=(0-1)/(6-3)

m=-1/3

y=-1/3x+2 *(0,2) co-ordinate means it's the y-intercept=c*

I think the slope is -1/3 and then just plt the points on the graph manually.

Alex swims at an average speed of 45m/min. How far does he swim in 1 minute and 24 seconds?

aksik [14]

Answer:

63 m

Step-by-step explanation:

We are given the following in the question:

Average speed of swimming = 45 m/min

Time = 1 minute 24 seconds

Converting time into minutes:

$=1 + \dfrac{\text{seconds}}{60}\\\\=1 + \dfrac{24}{60}\\\\=1.4\text{ minutes}$

Formula:

$\text{Speed} = \dfrac{\text{Distance}}{\text{Time}}$

Putting values, we get.

$45 = \dfrac{\text{Distance}}{1.4}\\\\\text{Distance} = 45\times 1.4 = 63\text{ m}$

Thus, Alex swims for 63 m in 1 minute and 24 seconds.

What is the perimeter of a square with an area of 169 square meters?

alekssr [168]

The area of a square is A=s^2

We already have the area, so we solve for the side length:

169=s^2

13=s

The perimeter of a square is P=4s

We plug in 13 for s:

P=4(13)

P=52

So the perimeter of the square is 52 m^2

Hope this helped!
