Subtract using a number line.
−2.3−(−0.4)
Plot the minuend and the difference on the number line.
The difference on the number line of the expression −2.3−(−0.4) is - 1.9
Number lines are lines that are used to mark integers based on the required interval between the integers
Given the expression
−2.3−(−0.4)
First, let us find the difference
= −2.3−(−0.4)
= −2.3 + 0.4
= -1.9
Hence the difference of the number is -1.9

A library wishes to build an access ramp for wheelchairs. The main entrance of the library is 8 ft. above sidewalk level. If the architect recommends a grade (angle of elevation) of 6°, how long must the access ramp be?
Answer:
About 76.5 ft.
Step-by-step explanation:
Draw a diagram of a right triangle. The shorter leg represents the height of the main entrance of the library, which is 8 ft. The longer leg won't matter in this case. The hypotenuse is what we're trying to find, so mark it as x. We know there's a 6° angle of elevation, so the 30° angle of the triangle will be 6° in this case. Now we have to use trig. Think of Soh Cah Toa. The 6° is opposite from 8 and the hypotenuse is x. So, the equation to find x would be:
sin (6°) = 8/x
Multiply both sides by x
sin (6°) * x = 8
Divide both sides by sin (6°)
x = 8/sin (6°)
When putting it into a calculator, your answer should be 76.534, which rounds to 76.5 ft.

Jeffery took a drive to town at an average rate of 50mph. When he returns, he drove back at the rate of 30 mph. If he spent a total of 8 hours traveling, what is the distance traveled by Jeffery? Please answer.
Answer:
150 + 150 = 300
Step-by-step explanation:
50x = 30y
x + y = 8
~~~~~~~~~~~~~~~
x = 8 - y
50(8-y) = 30y
400 - 50y = 30y
400 = 80y

Answer:
22.5 degrees and 67.5 degrees
Step-by-step explanation:
complementary angles add up to 90°
x + 3x = 90°
4x = 90
90/4 = x
x = 22.5
The first angle is 22.5
The second angle is 3 times as much
22.5 x 3 = 67.5

what is the distance between points (6,-5) and (2,-2)
Answer:
5.
Step-by-step explanation:
Distance = √(2-6)^2 + (-2-(-5)^2)

= √25
= 5.
Hello ;)
We can calculate the distance between two points by knowing their coordinates.
Here is the formula :
Let two points [tex]A(x_{A};y_{A})[/tex] and [tex]B(x_{B};y_{B})\\[/tex]
The distance between those two points is given by using this formula :
[tex]AB^{2} =(x_{B}-x_{A})^{2} +(y_{B}-y_{A})^{2}[/tex]
Now, we can use this formula in your exercice.
(2 - 6)² + (-2 - (-5))²
= (-4)² + 3²
= 16 + 9
= 25
Do not forget to do the square root of 25 ;)
So we obtain : [tex]\sqrt{25}=5[/tex]
The distance between points (6 ; -5) and (2 ; -2) is 5 units of lengh.

Calculate the volume of a warehouse that has inside dimensions of 22.4 meters by 11.3 meters by 5.2 meters.
The volume of the warehouse with the three dimensions is V = 1,316.224 cubic meters.
Given data:
To calculate the volume of the warehouse, you need to multiply its length, width, and height:
Volume = Length * Width * Height
The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle
Given the dimensions:
Length = 22.4 meters
Width = 11.3 meters
Height = 5.2 meters
Substitute these values into the formula:
Volume = 22.4 m × 11.3 m × 5.2 m
Calculate the result:
Volume = 1,316.224 m³
So, the volume of the warehouse is approximately 1,316.224 cubic meters.

4. Find the equation of the lines described.
A. Find the equation of the line parallel to y = 3x -5
and passing through
(-4, 7).
Answer:
y = 3x + 19
Step-by-step explanation:
Apply point-slope form. Our point (y1, y2) is (-4, 7) and our slope (m) is 3. The slope of y = 3x - 5 is 3 because it is "m" in y = mx + b. Parallel lines have the same slope.
y - y1 = m(x-x1)
y - 7 = 3(x-(-4))
y - 7 = 3(x+4)
y - 7 = 3x + 12
y = 3x + 19

For x-intercept:
put y=0
0=-1/4 x -15
1/4x=-15
x=-15×4
x=-60
points(-69,0)
For y-intercept:
put x=0
y=-1/4(0)-15
y=-15
points(0,-15)
This line will never pass through first quadrant.
Note:if you need to ask any question please let me know.
The line will never pass through first quadrant.
What is intercept?The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.
Given line:
y= -1/4 x-15
Now, the x-intercept:
0=-1/4 x -15
1/4x=-15
x=-15×4
x=-60
and the y-intercept will be
y=-1/4(0)-15
y=-15

Gordon makes 4/5 of a recipe with 2/3 bag of cheese. At this rate, what fraction of the bag of cheese will Gordon use to make the entire recipe?
Answer:
Gordon will use 5/6 of the bag of cheese to make the entire recipe.
Step-by-step explanation:
We are given that Gordon makes 4/5 of a recipe with 2/3 bag of cheese.
And we want to determine what fraction of the bag of cheese Gordon will use to make the entire recipe.
We can write the following ratio:
[tex]\displaystyle \frac{\dfrac{2}{3}\text{ bag of cheese}}{\dfrac{4}{5}\text{ recipe}}[/tex]
Find the unit rate. Multiply both layers by 5/4:
[tex]\displaystyle \frac{\dfrac{2}{3}\text{ bag of cheese}}{\dfrac{4}{5}\text{ recipe}}\times \frac{\dfrac{5}{4}}{\dfrac{5}{4}}[/tex]
Multiply:
[tex]\displaystyle \frac{\dfrac{5}{6}\text{ bag of cheese}}{1 \text{ recipe}}[/tex]
In conclusion, Gordon will use 5/6 of the bag of cheese to make the entire recipe.
