2 1/4 x4/5 ÷ 3/5 - 1/2
Answer:
2.5.2 1/2.Step-by-step explanation:
We need to solve in the most hard way.
Equation simplified:
((((2 1/4) * 4/5) / (3/5)) - (1/2)Solve left to right:
((((2 1/4) * 4/5) / (3/5)) - (1/2)= ((((2 1/4) * 4/5) / (3/5))= 3 - 1/2= 2 1/2.If we solve this separately, starting with 2 1/4 * 4/5 without dividing 3/5, we would be doing it wrong.
If we do it like this, we would get the correct answer.
2 1/2 is the answer.

Write the point slope form of the equation of the line through the given points: (-4,-1) and (-3,1)
EXPLAIN. STEP BY STEP
Answer:
SLOPE IS = 2
Step-by-step explanation:
to find the slope you should remeber the slope equation:
[tex]M=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
[tex](x_{1} ,y_{1} )=(-4,-1)\\(x_{2} ,y_{2} )=(-3,1)[/tex]
[tex]M=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }\\M=\frac{1-(-1)}{-3-(-4)}[/tex]
[tex]M=\frac{2}{1} \\M=2[/tex]
SLOPE IS =2
Five students each ate 2/3 of their own bag of skittles. What was the total amount eaten?
Answer:
Total number of students= 5
Each ate = 2/3
Total amount eaten=?
Then,
2/3×5
=10/3
Hence 10/3 is the total amount eaten.
Determine which of the lines, if any, are parallel or perpendicular. Explain.
Line a: -x+2y=3
Line b: -6x=3y-1
Line c: 4x-8y=5
Answer:
See below
Step-by-step explanation:
Let's rewrite all three equations is standard slope-intercept format of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).
Line a: -x+2y=3
2y = x + 3
y = (1/2)x + 3
Line b: -6x=3y-1
-3y = 6x - 1
y = -2x + (1/3)
Line c: 4x-8y=5
-8y = -4x + 5
y = (1/2)x - (5/8)
Parallel lines have the same slope (m). Perpendicular lines have slopes that are the negative inverse (-1/m)of each other.
Slopes, m, for the lines are;
a) (1/2)b) -2c) (1/2)The negative inverse of (1/2) is -2.
Lines a and c are parallel (same slope)
Line b is perpendicular since it's slope is the negative inverse of both a and b (-1/(1/2)) = -2

A spinner has three sections. The table shows the results of spinning the arrow on the spinner 80 times. What is the experimental probability of the arrow stopping over Section 1?.
Experimental probability of the arrow of spinner (rotated 80 times) stopping over Section 1 is one fourth or 0.25.
What is experimental probability?Experimental Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event during the experiment.
Given information-
Total number of sections in a spinner is 3.
Total number of times the trials done is 80.
The three section table given in the problem has the values as,
The values of the first column is section 1 and 20.The values of the second column is section 2 and 36.The values of the third column is section 3 and 24.The experimental probability of the arrow stopping over Section 1 has to be find out.
As the experimental probability of an event is the ratio of number of times it took place to the total trails. Thus the experimental probability of the arrow stopping over Section 1 is,
[tex]P=\dfrac{20}{80}\\P=\dfrac{1}{4}\\P=0.25[/tex]
Thus experimental probability of the arrow of spinner (rotated 80 times) stopping over Section 1 is one fourth or 0.25.

What is the answer to -x/4<7
Answer:
[tex]x>-28[/tex]
Step-by-step explanation:
Given the following question:
[tex]-x\div4<7[/tex]
In order to find the answer, we have to isolate the variable by multiplying four on both sides.
[tex]\frac{-x}{4} <7[/tex]
[tex]\frac{-x}{4} =x\times4[/tex]
[tex]7\times4=28[/tex]
[tex]-x>28[/tex]
[tex]-x\times-1=x[/tex]
[tex]28\times-1=-28[/tex]
[tex]x>-28[/tex]
Hope this helps.
Answer:
x>-28
Step-by-step explanation:
First to cancel out the fraction times the whole fraction by the denominator 4 AND the 7 then multiply 7*4=28
This leaves you with
-x<28
To get rid of the -x divide both sides of the inequality by -x, This also changes the sign of the inequality to > Because you are Dividing both sides of the inequality
Negative/Negative =positive
Positive/Negative =Negative
So, You get
x>-28

Advanced Trigonometry please help!!!!!
Answer:
i) Area = 25 m²
ii) slope of roof = 36.87°
Step-by-step explanation:
(i) Let the midpoint of AB = M
Find BC by using Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse of a right triangle)
Legs = MB and MC, hypotenuse = BC
⇒ 1.5² + 2² = BC²
⇒ 6.25 = BC²
⇒ BC = √(6.25) = 2.5
Area of a rectangle = width x length = BC x BE
⇒ area of BCFE = 2.5 x 5 = 12.5
⇒ area of ACFD = area of BCFE = 12.5
Therefore area covered by tiles = 12.5 + 12.5 = 25 m²
ii)
The angle of the slope of the roof will be angle ∠B of the right triangle ΔCMB.
Using sin(A)/a = sin(B)/b = sin(C)/c
sin(90)/2.5 = sin(B)/1.5
0.4 = sin(B)/1.5
0.6 = sin(B)
∠B = 36.87°

∠5 = x + 20
So,
∠2 = ∠5

3x - x = 20 + 20
2x = 40
x = 40/2
