A car travels at a speed of 55 km/h. Find the distance travelled by the car in 12 minutes 30 seconds , giving your answer in metres
Answers
Step-by-step explanation:
S=vt
v=55kmh^-¹
55×1000
=_______ms^-¹
60×60
=15.2778ms^-¹
t=12 min 30s
=12×60+30
=750s
so, s(distance)=750×15.2778 m =11458.35 m
Write an equation in slope-intercept form for the line with slope 2 and y-intercept 5. Then graph the line.
Answers
See image attached
Answer:
y = 2x + 5
Step-by-step explanation:
Slope-intercept form: y = mx + b
where:
m is the slopeb is the y-intercept (when x = 0)Given: a line with a slope of 2, and y-intercept of 5
Equation: y = 2x + 5
y-intercept: (0, 5)Randomly select y-values that will help you graph the equation:
when y = -9:
-9 = 2x + 5 [subtract 5 from both sides]
-9 - 5 = 2x
-14 = 2x [divide both sides by 2]
-14 ÷ 2 = 2x ÷ 2
-7 = x
coordinate: (-7, -9)
when y = -5:
-5 = 2x + 5 [subtract 5 from both sides]
-5 - 5 = 2x
-10 = 2x [divide both sides by 2]
-10 ÷ 2 = 2x ÷ 2
-5 = x
coordinate: (-5, -5)
when y = -1:
-1 = 2x + 5 [subtract 5 from both sides]
-1 - 5 = 2x
-6 = 2x [divide both sides by 2]
-6 ÷ 2 = 2x ÷ 2
-3 = x
coordinate: (-3, -1)
when y = 3:
3 = 2x + 5 [subtract 5 from both sides]
3 - 5 = 2x
-2 = 2x [divide both sides by 2]
-2 ÷ 2 = 2x ÷ 2
-1 = x
coordinate: (-1, 3)
With these coordinates, graph them on a coordinate plane and draw a straight line through them. That should be the graph of the equation.

Answers
Answer:
1.
[tex]y=\frac{1}{4}x+2[/tex]
m= [tex]\frac{1}{4}[/tex]
b= 2
2.
[tex]y=-\frac{1}{3}x+1[/tex]
m= [tex]-\frac{1}{3}[/tex]
b= 1
3.
[tex]y=3x+4[/tex]
m= 3
b=4
Step-by-step explanation:
1. The line intersects the y-axis at the point (0,2) therefore its y-intercept is b=2.
The line rises up 1 unit on the y-axis for every 4 units on the x-axis therefore the line has a slope of m=1/4.
Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that [tex]y=\frac{1}{4}x+2[/tex]
2. The line intersects the y-axis at the point (0,1) therefore its y-intercept is b=1.
The line down up 1 unit on the y-axis for every 3 units on the x-axis therefore the line has a slope of m= -1/3.
Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that [tex]y=-\frac{1}{3}x+1[/tex]
3. The line intersects the y-axis at the point (0,4) therefore its y-intercept is b=4.
The line rises up 3 units on the y-axis for every 1 unit on the x-axis therefore the line has a slope of m=3.
Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that [tex]y=3x+4[/tex]

What is the value of y in the equation 3(3y - 9) = 0?

Answers
Step-by-step explanation:
Use the Distributive Property in order to solve.
Distributive Example:[tex]a(b+c)=ab+ac[/tex]
Using the property into the equation:
[tex]3(3y-9)=3(3y)-3(9)=9y-27[/tex]
[tex]9y-27=0[/tex]
Add 27 to both sides:
[tex]9y=27[/tex]

Answers
Answer:
B) P' (-4, -4) and Q' (-1, -2)
Step-by-step explanation:
From inspection of the graph:
P = (-4, 4)
Q = (-1 ,2)
If the line PQ is reflected across the x-axis, then the x-coordinates of the points do not change, and the y-coordinates of the points become negative.
Therefore,
P' = (-4, -4)
Q' = (-1, -2)
Reflected over x axis so x co-ordinates remains constant.
The line is present in Quadrant 2 so it will be shifted to quadrant 3.
y co-ordinates will be negative.(In Q3 y<0)So the rule is (x,-y)
The co-ordinates are

184.6cm³ up you are rounding to the nearest tenth 184.56cm³ if you are rounding to the nearest hundredth
It's a hemisphere instead of a sphere so the formula is 2/3×π×r³ which gives us the equation of 2/3×π×4.45³ snd the reason we use 4.45 is because the diameter is 8.9 so we have to divide that by 2 to get the radius which is 4.45

The equation of a leftward parabola is [tex]\rm (y - 4)^2 = -4(x+ 3)[/tex]. Then the correct option is D.
What is the parabola?It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called the focus, and the non-movable line is called the directrix.
The parabola is open to the left.
We know that the equation of the parabola will be in square form.
a. [tex]\rm (x - 4)^2 = 4(y +3)[/tex]
This is an equation of an upward parabola.
b. [tex]\rm (x - 4)^2 = -4(y+ 3)[/tex]

Its width is___
its length is____
Answers
Answer:
Length will be 46 ft and width will be 16 ft
Explanation:
Let the width be x.
then the length will be 3x - 2
using the rectangle perimeter formula:
2( length + width )
2(x + 3x-2) = 124
2(4x-2) = 124
8x - 4 = 124
8x = 128
x = 16 ft
Width will be 16 ft and

Please select the best answer from the choices provided
Answers
Based on IRS regulations, the taxes withheld for a single person with 2 withholding allowances making $799 per period is C. $53.
IRS regulations in 2005 stated that when a person who is making at least $780 per payroll period, but not more than $800, and had 2 withholding allowances, they would have taxes withheld of $53.
The single person in this scenario is making $799 which falls into the above bracket so they will have taxes withheld of $53.
In conclusion, option C is correct.

Trapezoids A and B are similar. Find the values of x and y.
Answers
Step-by-step explanation:
when 2 shapes are similar, it means that all their angles are the same compared with each other.
and all distances (incl. side lengths) if one shape correlate to the corresponding distances in the other shadow by the same ratio or factor.
we have one side (30 m in A and 50 m in B), where we have both measures.
we see that the ratio to "go" from A to B is 30/50 = 3/5.
that means a distance in A is the same distance in B multiplied by 3/5.
and that factor is the same also for every other side.
therefore,
x = 15 m × 3/5 = 3 m × 3 = 9 m
y × 3/5 = 18 m
3y = 90 m
y = 30 m
