Answer:
Step-by-step explanation:
27 ) 2x² - x - 1 = 0
2x² - 2x + x - 1 = 0
2x ( x - 1) + (x - 1) = 0
(x - 1)(2x + 1) = 0
x - 1 = 0 ; 2x + 1 = 0
x = 1 ; 2x = -1
x = -1/2
x = 1 ; -1/2
Option b
28) Area of a rectangle = 24 cm²
length * width = 24
(3x +2 )(2x -1) = 24
3x(2x -1) + 2(2x - 1) = 24
3x *2x - 3x *1 + 2*2x - 2*1 = 24
6x² -3x + 4x - 2= 24
6x² + x - 2 -24 = 0
6x² + x - 26 = 0
6x² -12x + 13x - 26 = 0
6x(x - 2) + 13(x - 2) = 0
(x -2)(6x +13) = 0
x = 2 {Ignore 6x + 13 as it gives negative value}
length = 3x + 2 = 3*2 + 2 = 6 + 2 = 8 cm
Width = 2x - 1 = 2*2 - 1 = 4 - 1 = 3 cm
29) Area of square = 900 cm²
Side² = 900
(5x)² = 900
25x² = 900
x² = 900/25
x² = 36
x = √36 = √6*6
x = 6 cm
30) base = b cm
height = b + 2
Area of triangle = 24 cm²
[tex]\dfrac{1}{2}base*height = 24\\\\\dfrac{1}{2}*b*(b+2) = 24\\[/tex]
b(b + 2) = 24*2
b² + 2b = 48
b² + 2b - 48 = 0
b² - 6b + 8b - 48 = 0
b(b - 6) + 8(b - 6) = 0
(b - 6) (b + 8) = 0
b - 6 = 0 {Ignore b +8 = 0 as it gives negative value}
b = 6 cm
height = 6+ 2 = 8 cm

Product quantity is 560 products, average weight is 120g, knife level movement is 20g. Ask how many products in the range (100; 140g)
Answer:
Step-by-step explanation:
120 +-20 =(100 ; 140) -> X±k*σ= 100 =>k=1
According to Chebyshev, approximately 66.67% of the data lie within one standard deviation of the mean
->66.67%*560 = 373 products in (100;140)

a) Find the ratio of the number of boys to the number of girls in a class if the number of boys is
115 and that of girls is 46.
Answer:
5/7
Step-by-step explanation:
First calculate the total number of students:
Girls + boys
= 46 + 115
= 161
Then divide the number of boys over all students
= 115/161
= 5/7
X-6y=6 find an ordered pair
Answer:
(6,0) or (0,-1)
Step-by-step explanation:
X-6y=6
X=6+6y
X/6=1+y
X/6-1=y
y=X/6-1
We'll use substitution to solve the ordered pair. Let's say Y = 0. We'll insert it back into our equation.
0=X/6-1
1=X/6
6=X
(6,0)
We can also start with X being = 0.
y=0/6 -1
y=-1
(0,-1)

Given the two points, write the
I equation in slope-intercept form.
(-5, 2) and (10, 8)
Answer:
y = 2/5x + 4
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Slope:
( y1 - y2 ) / ( x1 - x2 )
( 2 - 8 ) / ( -5 - 10 )
( -6 ) / ( -15 )
2 / 5
Y-Intercept:
8 = 2/5(10) + b
8 = 4 + b
4 = b
