Mathematics
1 answer:
Daniel [21]3 years ago
4 0

Answer:

66.67%

Step-by-step explanation:

They do not say that I estimate a value of 350 chips but in reality there were 210 chips in total, we have that the error formula is:

Percentage error (%) = (estimated value - actual value) / actual value × 100 (in absolute value)

replacing:

Percentage error (%) = | 350 - 210 | / 210 × 100

Percentage error (%) = 140/210 * 100

Percentage error (%) = 66.67

Which means that the percentage error is 66.67%

How do you find a subtotal
jolli1 [7]

This is the hardest question I've answered all day.

One way to find a sub-total is by *simply* adding everything together, and a example would be below, buy yeah, you just add everything together.

For example:

Cookies (item # 594993) $2.98

Cake (item # 4354533) $4.50

Vans low tops (item # 594939) $60.00

Vans socks (item # 598993) $15.00

And just by adding all this, that how you would find the subtotal. Hope this helps! ;)

Suppose that in a normal half hour of practice, a tennis player expends 280 calories of energy.
sertanlavr [38]

Answer:

308 Calories

Step-by-step explanation:

So we start off with 280 as usual, but I will focus on the percent. The given percent is 110% "effort". What we would need to do here is, Firstly, change the percent into a decimal, and this is done by moving the decimal spot of 110%. What I mean is that 110.% and you move that little period over 2 times to the left and also remove the percent as for now because we will not need it. After that you would get 1.10. This is what we will multiply by. So if we did 280x1.10 it equals 308, and that is how I got 308

Hope this helps!

An express train travels 80km/h from Ironton to Wildwood. A local train, traveling at 48km/h, takes 2 hours longer for the same
masha68 [24]

Answer:

They are 240 kilometers apart.

Step-by-step explanation:

This question can be solved using the following relation:

v = \frac{d}{t}

In which v is the velocity, d is the distance and t is the time.

An express train travels 80km/h from Ironton to Wildwood.

Here we have v = 80, t = x. So

v = \frac{d}{t}

80 = \frac{d}{x}

d = 80x

A local train, traveling at 48km/h, takes 2 hours longer for the same trip.

This means that when v = 48, t = x + 2[tex]. So[tex]v = \frac{d}{t}

48 = \frac{d}{x+2}

Since d = 80x

48 = \frac{80x}{x+2}

Applying cross multiplication

80x = 48(x + 2)

80x = 48x + 96

32x = 96

x = \frac{96}{32}

x = 3

So the distance is:

d = 80x = 80*3 = 240

They are 240 kilometers apart.
