91.) A car is traveling at 5 m/s. How far has it gone in 12 seconds?
5 m/s · 12 s = 5 m · 12 = 60 m
Answer: in 12 seconds that car has gone 60 metres.
Answer:
A car travels at a constant rate of 5 metres per second.
That means that for every second,the car travels 5m/s.
The question is asking you for how far the car travelled after 12 seconds.Muntiply 12 to bottom and top.
5m/1s*12/12=60/12
The car travels 60 metre in 12 seconds

Point F is on line segment EG. Given FG = 3x – 5, EF = x, and
EG = 5x – 8, determine the numerical length of FG.
A line segment can have one or more points on it. The numerical length of FG is 4
Given that:
[tex]FG = 3x - 5[/tex]
[tex]EF = x[/tex]
[tex]EG = 5x - 8[/tex]
Because point F is on EG, then:
[tex]EG = EF + FG[/tex]
So, we have:
[tex]5x - 8 = x + 3x - 5[/tex]
[tex]5x - 8 = 4x - 5[/tex]
Collect like terms
[tex]5x - 4x = 8 - 5[/tex]
[tex]x =3[/tex]
Recall that:
[tex]FG = 3x - 5[/tex]
Substitute [tex]x =3[/tex]
[tex]FG = 3 \times 3 - 5[/tex]
[tex]FG = 9 - 5[/tex]
[tex]FG = 4[/tex]
Hence, the numerical length of FG is 4

Here is a room with two lasers. Your goal is to get to the opposite side of the room. However there is a catch; if you do not stay equidistant from each laser, you will be blasted. Describe in a Word document how you would find the straight-line path across the room. Be sure to use correct geometric terminology from what you have learned so far.
Step-by-step explanation:
we would calculate the line of sight between the 2 lasers.
then we would create a line that goes through the middle point between the 2 lasers and is perpendicular to the line between the lasers. if we are lucky, then "You" is on the same perpendicular line. if not, we need to shift our starting point to a point where the perpendicular line hits the wall of the room.
by following that perpendicular line precisely, we we always have the same distance from both lasers.

If three circular metal discs of equal thickness whose radii are 5cm, 20cm and 40cm are melted down to form one circular disc of the same thickness, find its radius.
Answer: 45 (cm)
Step-by-step explanation:
Since the discs have the same thickness, we will think about the areas.
Let say x the new radius:
[tex]\pi*5^2+\pi*20^2+\pi*40^2=\pi*x^2\\\Longrightarrow\ 5^2+20^2+40^2=x^2\\\\\Longrightarrow\ 2025=x^2\\\\\Longrightarrow\ x=\sqrt{2025} =45[/tex]

Hello! I'm looking for help on the question: 6 2/3 x 3/10 in simplest form. Thank you! ^^
Answer:
6/5 or 1 and 1/5
Step-by-step explanation:
To do this you need to multiply 6/1, 2/3, and 3/10 all together by cancelling out the numerator in 3/10 and the denominator for 2/3. Then you would be left with 6*2*1/10
This simplifies to 6*1/5 because of the 2*1/10 is 1/5, because 1/5 doubled is 1/10.
then multiply the numerator and 6 together to get 6/5.
Hope this helps!
Factor Completely.
25z^2 − 36w^2
Answer:
(5z-6w)(5z+6w)
Step-by-step explanation:
Hi there!
We're given the expression 25z²-36w² and we want to factor it.
The expression written as a difference of squares. The difference of squares is given as a²-b²=(a-b)(a+b)
Let's label the values of what is a² and b², and then try to determine what a and b are from that information
[tex]a^{2}=25z^2\\b^2=36w^2[/tex]
Alright then! Let's square root both sides to find what a and b are
[tex]\sqrt{a^2}=\sqrt{25z^2[/tex]
Which then means:
a=5z
And then for b:
[tex]\sqrt{b^2}=\sqrt{36w^2}[/tex]
b=6w
Now substitute those values into the formula
a²-b² = (a-b)(a+b)
[tex]25z^{2}-36w^2=(5z-6w)(5z+6w)[/tex]
Hope this helps!
Can you answer this math homework? Please!
Answer:
Question 1: c) 12.5 m/s
Question 2: a) The object is not moving.
Step-by-step explanation:
Question 1: 100(m) divided by 8(s) equals 12.5(m/s)
So she goes 12.5 meters per second (m/s).
Question 2: Distance = x variable (horizontal) because the distance depends on the time. Time = y (vertical) because the time is independent.
If the points on the distance or x axis stay the exact same while the time or y axis continues to change, this will lead to a straight horizontal line on a graph and mean that whatever it is being measured for distance, is staying still or 'constant'.

O -5=17
2.
Answer:
[tex] {x}^{2} + 5x = - 2[/tex]
arrange the equation according to general formula;
General formula: ax² + bx + c = 0
therefore:
[tex] {x}^{2} + 5x + 2 = 0[/tex]
Using the quadratic equation :
[tex]x = \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a} \\ [/tex]
a » 1, b » 5, c » 2
substitute:
[tex]x = \frac{ - 5± \sqrt{ {5}^{2} - (4 \times 1 \times 2) } }{(2 \times 1)} \\ \\ x = \frac{ - 5± \sqrt{17} }{2} [/tex]
therefore solutions are;
[tex]{ \boxed{ \boxed{x_{1} = \frac{ - 5 + \sqrt{17} }{2} }}} \: \: and \: \: { \boxed{ \boxed{x_{2} = \frac{ - 5 - \sqrt{17} }{2} }}}[/tex]

Nothing. It could be odd or even. You can't take the chance. So you need to start your list with 2y
That means that 2y + 2 is the second member in your list
2y + 4
2y + 6
2y + 8
2y + 10
But notice you only have 5 numbers. 2y + 10 cannot be the answer.
The answer must be 2y + 20
