Answer: 23.2 miles per hour
Step-by-step explanation:
He ran 100 meters in 9.63 seconds.
First convert the number of meters he ran to miles:
= 100 * 3.28
= 328 feet
= 328/5,280
= 0.062121212 miles
Convert the seconds to hours:
= 9.63 / 60
= 0.1605 minutes
= 0.1605/60
= 0.002675 hours
Speed in miles per hour is:
= 0.062121212 / 0.002675
= 23.22
= 23.2 miles per hour

-5(t + 3)= -30
Solve for the variable!! Please
Answer:
[tex]\huge\boxed{t=3}[/tex]
Step-by-step explanation:
[tex]-5(t+3)=-30[/tex]
METHOD 1:[tex]-5(t+3)=-30[/tex] divide both sides by (-5)
[tex]\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}[/tex]
[tex]t+3=6[/tex] subtract 3 from both sides
[tex]t+3-3=6-3\\t=3[/tex]
METHOD 2:[tex]-5(t+3)=-30[/tex] use the distributive property a(b + c) = ab + ac
[tex](-5)(t)+(-5)(3)=-30[/tex]
[tex]-5t-15=-30[/tex] add 15 to both sides
[tex]-5t-15+15=-30+15[/tex]
[tex]-5t=-15[/tex] divide both sides by (-5)
[tex]\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3[/tex]

The mean length of 11 adults' big finger is 14.1cm.
What is the mean length (rounded to 2 DP) of these 21 people's big finger?
Answer:
The mean length of 10 children's big finger is 8.1 cmAverage length of all the 10 children's finger is (8.1×10) cm = 81 cm.
The mean length of 11 adult's big finger is 14.1 cmAverage length of all the 11 adult's big finger is (14.1×11) cm =155.1
Mean length of these 21 people's big finger is[tex] \frac{(81 + 155.1)}{21} = 11.242857[/tex]Hence, 11.24 is the right answer.A. I and II ONLY

The statement supported the graph is
The axis of symmetry is x = 3
The coordinates of the y-intercept are (0,7)
What is axis of symmetry?A line that divides an object into two equal halves and produces a mirror-like reflection of each side of the object is known as an axis of symmetry.
1. The axis of symmetry is x = 3
The axis of symmetry is the central axis of the graph, which signifies the middle point of the graph. It is evident that this graph is centered on x = 3.
2. The coordinates of the y-intercept are (0,7)
The y intercept is the point where the graph meets the y-axis, that is, the value of y on the graph when x=0.
From the graph, the coordinates of the y-intercept is (0, 7)
3. The X-intercept is located at (-3,0)
The x intercept is the point where the graph meets the x-axis, that is, the value of x on the graph when y=0.
From the graph the curve x axis at x= 1.5 and x= 4.5
So, the x-intercept is truly located at (1.5, 0) and (4.5,0)

In this case, we need to substitute n with 10.
So, it is like this: f(10) = 3(10) + 4
f(10) = 3(10) + 4
f(10) = 30 + 4

2x+3y=4 y+3x=6
find x and y
Answer:
x=-3/2y+2
y= y=−3x+6
Step-by-step explanation:
solve for x.
2x+3y=4
Add -3y to both sides.
2x+3y+−3y=4+−3y
2x=−3y+4
Divide both sides by 2.
2x/2= -3+4/2
x= -3/2 y+2
solve for y.
y+3x=6
Add -3x to both sides.
3x+y+−3x=6+−3x
y=−3x+6

a bus travels 320 miles in 6.4 hours. if the bus continues at the same rate, which proportion can be used to find m, the number of miles the bus will travel in 9 hours.
Answer:
A
Step-by-step explanation:
Ok first we need to find rate of MILES per HOUR
320/6.4=50
m= miles in 9 hours
9*50=450
Cross Multiplyis your answer
A
(6.4*9)/320m=Hours/miles
Hope this helps!
The number of miles the bus will travel in 9 hours will be 6.4 / 320 = 9 / m. Then the correct option is B.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
A bus travels 320 miles in 6.4 hours. if the bus continues at the same rate.
We know that speed is the ratio of distance and time. Then we have
The number of miles the bus will travel in 9 hours will be
320 / 6.4 = m / 9
6.4 / 320 = 9 / m
Then the correct option is B.

How can you write the equation for a linear function if you know only two ordered pairs for the function? Drag tiles tho complete the explanation. Tiles may be used once, more than once, or not at all.
Answer:
Explanation below
Step-by-step explanation:
First determine the slope using (y2-y1)/(x2-x1)
Then set up point slope form and add in an ordered pair for x and y to determine the y intercept: y - y1 = m(x - x1). Solve for y and you'll end up with slope intercept form.
For example: (-2,1), (3,2) find slope and y intercept.
(2-1)/(3-(-2))= 1/5
y-2=.2(x-3)
y=.2x-.6+2
y=.2x+1.4 or y=(x/5)+(7/5)
If the points are (-10, 3), (-2, 10) what is the slope?
Answer:
= 7/ 8
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 10-3)/( -2 - -10)
= ( 10-3)/( -2 +10)
= 7/ 8
