A car is travelling in the velocity of 20 m/ s . After 30 sec it covers a distance of 1200 m. Calculate the acceleration of car and the final velocity of the car
Answer:
given values are:
u=20 m/st= 30 ss= 1200 mv= ?a=?s = ut + 1/2 at²1200 = 20×30 + 1/2 × 30²a
1200= 600 + 1/2 × 900a
600 = 450a
a = 600 / 450
a = 1.33 m/s²
v²= u² +2asv² = 20² +2 × 1.33 × 1200
v²= 400 + 3192
v = √3592
v = 59.9 ≈ 60 m/s

Answer:
A. StartFraction (x + 5) (x + 2) Over x cubed minus 9 x EndFraction
Step-by-step explanation:
Given:
(2x + 5) / (x² - 3x) - (3x + 5) / (x³ - 9x) - (x + 1) / x² - 9
Factor the denominators
(2x + 5) / x(x - 3) - (3x + 5) / x(x - 3)(x + 3) - (x + 1) / (x - 3)(x + 3)
Lowest common multiple of the 3 fractions is x(x - 3)(x + 3)
= (2x+5)(x+3) - (3x + 5) - (x + 1)x / x(x - 3)(x + 3)
= (2x²+6x+5x+15) - (3x + 5) - (x² + x) / x(x - 3)(x + 3)
= 2x² + 11x + 15 - 3x - 5 - x² - x / x(x - 3)(x + 3)
= x² + 7x + 10 / x(x - 3)(x + 3)
Solve the numerator.
Solve the quadratic expression by finding two numbers whose product is 10 and sum is 7
The numbers are 5 and 2
= x² + 5x + 2x + 10 / x(x - 3)(x + 3)
= x(x + 5) + 2(x + 5) / x(x - 3)(x + 3)
= (x + 5)(x + 2) / x(x - 3)(x + 3)

The lengths of two sides of a triangle are 11 cm and 19 cm. Identify the range of possible lengths for the third side.
Answer:
2nd option
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is in the range
difference of 2 sides < x < sum of 2 sides , that is
19 - 11 < x < 19 + 11
8 < x < 30
Answer:
8 < x < 30
Step-by-step explanation:
The rule for side lengths of a triangle is:
the sum of two side's must be bigger than the third side and their difference must be smaller than the third side :
19 - 11 < x < 19 + 11
8 < x < 30

Answer 3. -7.5 is located to the left of 6.5 on a number line oriented from left to right.
If (m,2m+1) is a solution of the equation x +3y=7, find the value of m
Answer: m = 4/7
Step-by-step explanation:
x = m
y = 2m+1
so
x+3y = 7
or, m+3(2m+1) = 7
or, m + 6m+3 = 7
or, 7m = 4
so m = 4/7
The perimeter of a rectangular plot of land whose length is (2x+5) and width is (x-10) is 80cm. Find the
i)value of x
ii) area
iii)cost of weeding the plot at GHc 0.24 per m²
Answer:
P.=2(2x+5)+2(x-10)=80cm
6x-10=80
x=90/6=15cm
Area= L*W= 35*5=175 squared cm= 0.0175 squared m
Cost= 0.24 * 0.0175 = GHc 0.0042
A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. The cost of weeding the rectangular plot is 0.0042 GHc.
What is a rectangle?That parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. A rectangle is always a parallelogram and a quadrilateral but the reverse statement may or may not be true.
A.) The perimeter of a rectangular plot of land whose length is (2x+5) and width is (x-10) is 80cm. Therefore, we can write,
Perimeter of the rectangel = 2(L+W)
80 = 2[(2x+5)+(x-10)]
80/2 = 2x+5+x-10
40 = 3x -5
40+5 = 3x
x = 15
Hence, the value of x is 15.
B.) The length of the rectangle = (2x+5) = 2(15)+5 = 35 cm = 0.35 m
The width of the rectangle = (x-10) = 15-10 = 5 cm = 0.05 m
Now, the area of the rectangle = L×B = 0.35m × 0.05m = 0.0175m²
C.) Given the cost of weeding 1m² is 0.24, therefore, the cost of weeding the rectangular plot is
Cost = 0.0175 × 0.24 = 0.0042 GHc
Hence, the cost of weeding the rectangular plot is 0.0042 GHc.

Given right triangle ABC, what is the value of tan (A)
O 5/13
O 12/13
O 12/5
O 13/12
Answer:
12/5
Step-by-step explanation:
Recall that trig function tan = opposite / adjacent
Find tan A
Opposite side of angle A = 24
Adjacent of A = 10
Tan (A) = 24/10
24/10 can be simplified to 12/5
Answer:
[tex]\frac{12}{5}[/tex]
Step-by-step explanation:
Tan is equal to [tex]\frac{opposite}{adjacent}[/tex]. The side opposite to angle A is BC while the side adjacent to it is AC. This means tan(A) is [tex]\frac{BC}{AC}[/tex]. It is given that BC is 24 and AC is 10, so we can substitute those values in and simplify:
tan(A) = [tex]\frac{24}{10} = \frac{12}{5}[/tex]
The denominator of a fraction is 5 more than the numerator. if both the numerator and denominator are increased by 3, the the resulting fraction becomes 3/4. find the original fraction.
Answer:
12/17
Step-by-step explanation:
Let
Numerator of the fraction = x
Denominator of the fraction = x + 5
The fraction is
x / (x + 5)
if both the numerator and denominator are increased by 3, the the resulting fraction becomes 3/4.
x + 3 / (x + 5) + 3 = 3/4
x + 3 / x + 8 = 3/4
Cross multiply
(x + 3)4 = (x + 8)3
4x + 12 = 3x + 24
4x - 3x = 24 - 12
x = 12
Recall,
x / (x + 5)
= 12 / (12 + 5)
= 12/17
The original equation = 12/17
find the value of x.

Trong một lớp học có tỉ số học sinh nam và nữ là 7: 5.Tìm số học sinh của lớp biết số học sinh nam lớn hơn số học sinh nữ là 6 học sinh
Answer:
Học sinh nam là 21 học sinh, số học sinh nữ là 15 học sinhH
Step-by-step explanation:
Tỉ số giữa nam và nữ là x/y = 7/5 => x/7 = y/5
áp dụng tính chất của dãy tỉ số bằng nhau, ta được:
x/7 = y/5 => x-y =/7-5 = 6/2 = 3
Vì x/7 = 3 => x = 21
y/5 = 3 => y= 15
Vậy số học sinh nam là 21 học sinh, số học sinh nữ là 15 học sinh
