Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
4.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

Pulling out like terms :
8.1 Pull out like factors :
-17x2 - 14x + 10 = -1 • (17x2 + 14x - 10)
Trying to factor by splitting the middle term
8.2 Factoring 17x2 + 14x - 10
The first term is, 17x2 its coefficient is 17 .
The middle term is, +14x its coefficient is 14 .
The last term, "the constant", is -10
Step-1 : Multiply the coefficient of the first term by the constant 17 • -10 = -170
Step-2 : Find two factors of -170 whose sum equals the coefficient of the middle term, which is 14 .
-170 + 1 = -169
-85 + 2 = -83
-34 + 5 = -29
-17 + 10 = -7
-10 + 17 = 7
-5 + 34 = 29
-2 + 85 = 83
-1 + 170 = 169
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
-17x2 - 14x + 10

In ΔOPQ, q = 83 inches, p = 80 inches and ∠P=70°. Find all possible values of ∠Q, to the nearest degree
Answer:
77.12°
Step-by-step explanation:
Given that:
In triangle OPQ
∠P=70°
line q = 83 inches
line p = 80 inches
To find ∠Q; we use the since rule:
[tex]\dfrac{Sin \ Q}{q} = \dfrac{Sin \ P}{p}[/tex]
[tex]\dfrac{Sin \ Q}{83} = \dfrac{Sin \ 70}{80}[/tex]
[tex]Sin \ Q= \dfrac{Sin \ 70 \times 83}{80}[/tex]
[tex]\text{Sin \ Q= 0.9749}[/tex]
[tex]Q=Sin ^{-1}( 0.9749)[/tex]
[tex]\mathbf{Q = 77.12^0}[/tex]
Solve the following equation for x.
3x - 9 = -42
Answer:
x = -11
Step-by-step explanation:
Add 9 to both sides of the equation
3 − 9 = −42
3 − 9 + 9 = −42 + 9
Simplify
Add the numbers
3 = −33
Divide both sides of the equation by the same term
3 = −33
3/3 = −33/3
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
= −11

Answer:
x = 1.75
Step-by-step explanation:
Given
3.5(2.25 + x) = 14 ( divide both sides by 3.5 )
2.25 + x = 4 ( subtract 2.25 from both sides )
x = 1.75

Step-by-step explanation:
round 34 1/8 to the nearst whole number
Answer:
34
Step-by-step explanation:
Because it is a mixed fraction, it tells us the whole number already. After that, we need to look at the actual fraction part and decide if it's large enough to round the whole number up. 1/8 is not, so we keep the whole number at 34
Answer:
That would be 34

what percent of 82 is 9.75. Round your answer to the nearest tenth
Hi there!
8 would be the nearest ten of 7.995..
1.Multiply 82 with 0.01:
[tex]82[/tex]·[tex]0.01=0.82[/tex]
2.Multiply the terms:
[tex]0.82[/tex]·[tex]9.75=7.995[/tex]
3.Round the term:
[tex]7.995=8[/tex]
Therefore, 82% of 9.75 in nearest tenth is 8.

Answer:
m = 2
Step-by-step explanation:
∠ GLI = 90°
∠ GLH + ∠ HLI = ∠ GLI , that is
9m + 25m + 22 = 90
34m + 22 = 90 ( subtract 22 from both sides )
34m = 68 ( divide both sides by 34 )
m = 2
Then
∠ HLG = 9m = 9 × 2 = 18°

100 points ! What is the area of the following composite figure? All angles are right angles.
24 m^ 2
27 m ^2
29 m^ 2
22 m^ 2
Answer:
24m²
Step-by-step explanation:
..,.................
Area = 5*4+2*1+2*1
Area = 20+2+2
Area = 24m²
Answer:
24 m^2
Step-by-step explanation:
We need to study the structure well
We can find the magnitude of the big rectangle. We will need to find the total length and total breadth of the big rectangle
Then we remove the area of the four squared cut out from the big rectangle.
Total length of the rectangle is 5+1+1=7m
Then the length of the breath of the rectangle is 2+1+1=4m
So area of rectangle is given as length × breadth
Area= l×b
Area=7×4=28m²
Area of the big rectangle is 28m²
Then the squared is made of dimension 1m by 1m
Area of a square is s²
Then, a=1m
Area of the square= 1²=1m²
There are four squared side
Then, the total area of the four squared is 4×1=4m²
Then the required area is
Area=Total area - area of four squared side
Area=28m²-4m²
Area =24m²
Area of the figure is 24m²
The correct option is A.

Answer: 15 √ 2
Step-by-step explanation:
Equilateral triangles have three equal side lengths, three equal angles of 60 degrees, and three equal altitudes.
You would think that the height of an equilateral triangle would also be equal to it's sides, but it's not. The formula for height is: side/2 x √3
10√6 / 2 * √ 3 = 15 √ 2
The decimal form: 21.2
The number of people who sleep 8-8.9 hr per night is about how many times the number who sleep 6-6.9 hr a night
Answer:
3.75 times
Step-by-step explanation:
From the histogram plot of the data :
The number of people who sleep 8 - 8.9 hour per night is about 375
The number of people who sleep 6 - 6.9 hour per night is about 100
Therefore, to compare how many times the number of people who sleep 6 - 6.9 hrs and 8 - 8.9 hrs :
8 - 8.9hrs = 6 - 6.9 hrs * x
375 = 100x
x = 375 / 100
x = 3.75
Hence, the number of people who sleep 8 - 8. 9 is 3.75 times the number of people who sleep 6 - 6.9
