A bus is moving at a pace of 43.65 miles in 0.4 of an hour. How many miles will this car travel in 3 hours?
Speed of car in first 15 minutes = 40 km/h
Distance covered = speed × Time taken
60 minutes = 1 hour
15 minutes =
60
15
hour
Distance covered = 240×
60
15
=10km
Speed of car in next 15 minutes = 60 km/h
Distance covered = 60×
60
15
=15km
∴ Total distance covered = (10+15)km = 25 km
∴ 25 km is correct

Solve the expression and find the value of x.
[tex] \frac{x + 1}{10} - \frac{3(x - 1)}{5} = 2 [/tex]
[tex]\large\underline{\sf{Solution-}}[/tex]
[tex]\sf \dfrac{x + 1}{10} - \dfrac{3(x - 1)}{5} = 2[/tex]
[tex]\sf\longmapsto \dfrac{x + 1}{10} - \dfrac{3x - 3}{5} = 2[/tex]
[tex]\sf\longmapsto \dfrac{(x + 1) - 2(3x - 3)}{10} = 2[/tex]
[tex]\sf\longmapsto \dfrac{x + 1 - (6x - 6)}{10} = 2[/tex]
[tex]\sf\longmapsto \dfrac{x + 1 - 6x + 6}{10} = 2[/tex]
[tex]\sf\longmapsto \dfrac{ - 5x + 7}{10} = 2[/tex]
[tex]\sf\longmapsto - 5x + 7 = 20[/tex]
[tex]\sf\longmapsto - 5x = 20 - 7[/tex]
[tex]\sf\longmapsto - 5x = 13[/tex]
[tex]\sf\therefore x = - \dfrac{13}{5} [/tex]
Hence, the value of x will be -13/5 respectively.
[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]
[tex]\frac{x + 1}{10} - \frac{3(x - 1)}{5} = 2 \\ [/tex]
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
[tex]\frac { x + 1 } { 10 } - \frac { 3 ( x - 1 ) } { 5 } = 2 \\ \frac { x + 1 } { 10 } - \frac { 3 ( x - 1 ) } { 5 } = \frac{2}{1} [/tex]
Take a look at the denominators. The denominators are 10, 5 & 1. Their LCM is 10. So, multiply the fractions on both the sides of the equation by 10.
[tex]\frac { x + 1 } { 10 } - \frac { 3 ( x - 1 ) } { 5 } = \frac{2}{1} \\ \frac{x + 1}{10} \times \frac{1}{1} - \frac{3x - 3}{5} \times \frac{2}{2} = \frac{2}{1} \times \frac{10}{10} \\ \frac{x + 1}{10} - \frac{6x - 6}{10} = \frac{20}{10} [/tex]
Now cancel the denominators (as they have the same value) & take the numerators.
[tex]x + 1 - (6x - 6) = 20 \\ [/tex]
Now, simplify it.
[tex]x + 1 - (6x - 6) = 20 \\ x + 1 - 6x + 6 = 20 \\ x - 6x + 1 + 6 = 20 \\ - 5x + 7 = 20 \\ - 5x = 13 \\ x = -\frac{13}{5} \\ \boxed{ \boxed{ \bf x = - \frac{13}{5} =\: - 2 \frac{3}{5} = - 2.6}}[/tex]

Answer:
The answer is a.
Step-by-step explanation:
The equation formula is y=mx+b. M stands for the slope. B stands for the y-intercept. In the question, it says that your slope is 3/8 and that your y-intercept is -2. Remember, if it says (0, -2), and 0 is your x-coordinate, it means that it is a y-intercept. So, plug in the numbers into the formula and the equation should be: y=3/8x-2

Step-by-step explanation:
we have one large rectangle and 2 small right-angled triangles to add.
the area of the rectangle is easy : 15×25 = 375
the right-angled triangle on the long side has one side = 5, and the "invisible" side is 25 - 12 - 5 = 8.
these 2 sides are hitting each other in a right angle and can therefore be used as baseline and height of the triangle.
the area of a triangle is baseline×height/2.
so, the area of the this triangle is 8×5/2 = 20.
the right-angled triangle on the right short side has one side = 5, and the "invisible" side is 15 - 10 = 5.
these 2 sides are hitting each other in a right angle and can therefore be used as baseline and height of the triangle.
so, the area of the this triangle is 5×5/2 = 12.5.
so the total area is
375 + 20 + 12.5 = 407.5

Add like terms. Real terms are added; imaginary terms are added.
(√3 -i) + (2-√3i) = (√3 +2) +(-i -√3i)
= (√3 +2) -i(1 +√3) . . . . . the common factor of -i can be factored out

Which of the following describes the parabola with the equation y = 4x^2 − 12x + 9?
A. The axis of symmetry is x = 4 and the vertex is (4, −12).
B. The axis of symmetry is x = −1.5 and the vertex is (−1.5, 36).
C. The axis of symmetry is x = 0 and the vertex is (0, 9).
D. The axis of symmetry is x = 1.5 and the vertex is (1.5, 0).
Answer:
D. The axis of symmetry is x = 1.5 and the vertex is (1.5, 0).
Step-by-step explanation:
y=4x^2-12x+9:\quad \mathrm{Parabola\:with\:vertex\:at}\:\left(h,\:k\right)=\left(\frac{3}{2},\:0\right),\:\mathrm{and\:focal\:length}\:|p|=\frac{1}{16}
To find the vertex of this parabola, "complete the square:" Rewrite y = 4x2 - 12x + 9 in the form y = 4(x - h)^2 + k:
y = 4x^2 - 12x + 9 => y = 4(x^2 - 3x) + 9.
Now complete the square of x^2 - 3x: Take half of -3 and square the result, obtaining (-3/2)^2, or 9/4. Add 9/4 to x^2 - 3x and then subtract 9/4 from the result: We get x^2 - 3x + 9/4 - 9/4. Substitute this result back into
y = 4(x^2 - 3x) + 9: y = 4(x^2 - 3x + 9/4 - 9/4) + 9
and then rewrite the perfect square x^2 - 3 + 9/4 as the square of a binomial:
y = 4(x - 3/2)^2 - 9/4) + 9. This simplifies to:
y = 4(x - 3/2)^2 + 0.
Thus, the vertex is at (3/2, 0) and the axis of symmetry is x = 3/2. This agrees with Answer B.
Given : equation y = 4x^2 − 12x + 9
To Find :
A) The axis of symmetry is x = 0 and the vertex is (0,9).
B)The axis of symmetry is x= 1.5 and the vertex is (1.5, 0).
C)The axis of symmetry is x = 4 and the vertex is (4, -12).
D)The axis of symmetry is x = -1.5 and the vertex is (-1.5, 36).
Solution:
y = 4x² - 12x + 9
=> y = (2x)² - 2(2x)3 + 3²
=> y = (2x - 3)²
=> y = 4(x - 3/2)²
=> y = 4(x - 1.5)²
Axis of symmetry is x= 1.5
Vertex = (1.5 , 0)
The axis of symmetry is x= 1.5 and the vertex is (1.5, 0).
For the piecewise defined function f (x)=
3x-1 x<3
1/2 x + 7. x>3
what is the following is the value of f (6) ?
Answer:
10
Step-by-step explanation:
f(x)=f(6) means x=6
Now, as 6>3 we use the formula for x>3
Substituting 6 into 1/2x+7 we get,
1/2(6)+7
=3+7
=10
The value of function at x= 6 is 10.
What is Piecewise function?A piecewise-defined function in mathematics is one that is composed of several smaller functions, each of which has a certain interval of the domain it applies to. Instead of being a property of the function itself, piecewise definition is a means to express the function.
We have,
f(x) = 3x -1 , x<3
1/2x + 7, x>3
Now, for x = 6 which falls in condition x>3
f(6) = 1/2(6)+ 7
f(6) = 3 + 7
f(6)= 10

A) 2
B) 4
C) 3
D) 5
Answer:
D) 5
Step-by-step explanation:
To find the unit rate or the amount of shoes per hour. Take the amount of shoes sold and divide by how many hours. On Monday he sold (15/3) or 5 shoes per hour and on Tuesday he sold (20/4) or 5 shoes sold per hour again.
Susan made $357 for 17 hours of work.
At the same rate, how much would she make for 9 hours of work?
