Answer: 10.7%
Step-by-step explanation:
The percentage error will be calculated as:
Estimated value - Actual value / Actual value × 100
= (40 - 48) / 48 × 100
= 8/48 × 100
= 1/6 × 100
= 10.7%

What is the slope of the line that contains these points? xxx -4−4minus, 4 -3−3minus, 3 -2−2minus, 2 -1−1minus, 1 yyy 222 555 888 111111
Given:
The table of values is
x y
-4 2
-3 5
-2 8
-1 11
To find:
The slope of the line that contains these points.
Solution:
From the given table consider any two point.
Let the line passes through the points (-4,2) and (-3,5). So, the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-2=\dfrac{5-2}{-3-(-4)}(x-(-4))[/tex]
[tex]y-2=\dfrac{3}{-3+4}(x+4)[/tex]
[tex]y-2=\dfrac{3}{1}(x+4)[/tex]
Using distributive property, we get
[tex]y-2=3x+12[/tex]
[tex]y=3x+12+2[/tex]
[tex]y=3x+14[/tex]
Therefore, the required equation of line is [tex]y=3x+14[/tex].
Answer: The slope is 1/5.
Step-by-step explanation:
You can find the answer by subtracting 6-1, (5) and 0-1,(1), which shows you 1/5. (Explanation sucks, sorry)

3. Compute the product axb in each of the
following cases:
a) a = -7.5
and b=0.25 ;
b) a = -2.5
and b=-18;
c) a = -812
and b=-0.75;
d) a = 4.25 and b= -326.
Answer:
a). -7.5*0.25 = -1.875
b). -2.5*(-18) = 45
c). -812*(-0.75) =609
d). 4.25*(-326) = -1385.5
What is BC in simplest radical form
Answer:
Step-by-step explanation:
Draw altitudes from A and D to get two 30°-60°-90° triangles.
The sides of a 30°-60°-90° triangle are in the ratio 1:√3:2.
BC = 3√3 + 16 + 9√3 = 16 + 12√3

The dimensions of a square are altered so that one dimension is increased by 7 feet, while the other is decreased by 2 feet. The are of the resulting rectangle is 90ft^2. Find the original area of the square.
Answer:
64 ft^2
Step-by-step explanation:
(x+7)(x-2)=90
x^2-2x+7x-14=90
x^2+5x-104=0

Find x and y plz help
Answer:
x = 6.81 and y = 4.20
Step-by-step explanation:
by using SOHCAHTOA
hypotenus = 8
adjacent = x
opposite = y
sin45° = y/8
y = 8sin45°
y = 6.66
cos45° = x/8
x = 8cos45°
x = 5.66

I need help using the Expand Group and Factoring method on this problem.
27a^2+72a+28
Answer:
1 x (27a^2+72a+28) or 1(27a^2+72a+28)
Step-by-step explanation:
First find the GCF (greatest common factor) of 27a squared 72a and 28. It is 1 because there is nothing else that can go in.
So put 1 outside the parentheses and keep the terms
1 x (27a^2+72a+28)

Graph the following features:
• Slope = 2
Y-intercept = -5
y = mx + b
y = 2x - 5
you can go to desmos calculator online and simply put in the equation. but what you're going to do is find -5 on the y axis. then you will go up 2 and then 1 to the right.
it should look like this:

The Milgram Family drove 440 miles on 20 gallons of gas. At this rate, how many miles can they drive on 25 gallons of gas? *
Answer:550
Step-by-step explanation: first you need to find the unit rate ( or how many miles per gallon) by dividing 440 by 20 which would get 22, then you would take that and multiply it by 25 to get 550. Hope this helps!
