PLEASE HELP, DUE TOMORROW​

Mathematics
1 answer:
navik [9.2K]3 years ago
5 0

Answer:

2% (rounded to nearest percent)

Step-by-step explanation:

The formula is already given.

From the problem, we can say that:

Actual Value = 13.6

Experimental Value = 13.3

To find percentage error, we use the formula [remember, the numerator of the formula has absolute value, so if we find any negative answer, that would becomes positive value]. lets do this:

Percent Error = \frac{|13.3-13.6|}{13.6}*100\\=\frac{|-0.3|}{13.6}*100\\=\frac{0.3}{13.6}*100\\=0.0221*100\\=2.21

So, 2.21%

Rounded to nearest percent, that would be 2%

How would I solve the equations: y = x-4 and y=x^2-4x using substitution
andriy [413]

Answer:

x = 6

Explanation:

y = x - 4

26 = 4x + y


If y = y, then we can rewrite this system as this: 4x + x - 4 = 26


Then we combine like terms and add 4  on both sides to give us  5  x  =  30 . Divide by 5 on both sides and we arrive at the solution: x = 6

Please find the perpendicular line slope equation please! Thanks!
lana66690 [7]

We need to convert this equation to slope-intercept form first.

We can do that by solving for y.

x - 5y = 15

<em><u>Add 5y to both sides.</u></em>

x = 5y + 15

<em><u>Subtract 15 from both sides.</u></em>

x - 15 = 5y

<em><u>Divide both sides by 5.</u></em>

y = 1/5x - 3

We now know the slope is 1/5.

The slope of the line perpendicular to the line with a slope of 1/5 is -5.

The slope of a perpendicular line is the negative reciprocal of the original slope.

Using a graphing calculator, we know the y-intercept of the line that is perpendicular to the original line must have a y-intercept of -6 to run through the points (-2, 5).

The equation of the new line is y = -5x - 6.

A fruit stand sells apples, peaches and tomatoes. Today, they sold 4 apples for every 5 peaches. They sold 2 peaches for every 3
Brrunno [24]

Answer:

He sold 32 apples, 40 peaches and 60 apples.

Step-by-step explanation:

We are given that

4 apples are sold every 5 peaches and

3 tomatoes are sold every 2 peaches.

i.e. the ratio is apples: peaches = 4 : 5     ...... (1)

and the ratio peaches: tomatoes = 2 : 3   ...... (2)

Peaches are the common link here in both the ratio terms.

Let us make the peaches value in both the <em>ratio as 10 </em>to make it equal in both the ratio terms.

Multiply (1) by 2 and (2) by 5:

The ratio becomes;

apples:peaches = 8:10

peaches: tomatoes = 10:15

In other words, the ratio becomes:

apples:peaches:tomatoes = 8:10:15

Let the number of apples = 8x

Let the number of peaches = 10x\\

Let the number of tomatoes = 15x

We are given that total fruits are = 132

\Rightarrow 8x+10x+15x = 132\\\Rightarrow 33x = 132\\\Rightarrow x =4\\

So, number of apples sold = 8 \times 4 = 32

Number of peaches sold = 10 \times 4 = 40

Number of tomatoes sold = 15 \times 4 = 60
