Mathematics

natali 33 [55]1 year ago

Answer:

44.7

Step-by-step explanation:

Speed = distance / time

speed from distance a to b = 50 = 10 / time

time = 10/50 = 12 minutes

Speed from a to c = 62 = distance / 30 minutes

distance = 62 x 0.5 = 31 m

diatance from b to c = 31 - 10 = 21

time = 30 - 12 = 28 minutes

speed = 21 / 28 minutes

31 / 0.47

A 100-square grid has 70 shaded squares. Explain how you could express this model as a fraction, percent, and decimal.
slava [35]
The fraction of squares shaded to total squares is 70/100  or 7/10
With a percent, 70% of all of the squares are shaded
With a decimal, there are 0.7 shaded blocks for every total block, so it is 0.7
Hope this helps!

The minimum of the graph of a quadratic function is located at (-1,2) . the point (2,20) is also shown on the parabola . which f
Gekata [30.6K]
The complete question in the attached figure

we know that
the equation of a parabola is
y=a(x-h)²+k
where
(h,k) is the vertex   --------> (h,k)--------> (-1,2)
so
y=a(x+1)²+2

point (2,20)
for x=2
y=20
20=a(2+1)²+2--------> 20=a*9+2--------> 9*a=18---------> a=2

the equation of a parabola is
y=a(x+1)²+2-------> y=2(x+1)²+2

therefore

the answer is the option
<span>C) f(x) = 2(x + 1)2 + 2</span>

the table shows different ways that cameron can display his 12 model cars on shelves. How many shelves will display 2 cars if 8
Lera25 [3.4K]

Answer:

4 shelves

Step-by-step explanation:

if there is 8 shelves that display 1 car then that means there is 8 cars total.

so if you need a total of 12 cars then you would do (total of cars needed - total of cars you have).

(12-8) which would equal 4.

you need 4 cars left but on each shelf going forward needs to have 2 cars on it.

now since you have 4 cars you would divide that by the amount of cars on each shelf going forward.

4/2) which equals 2.

you need 2 more shelfs for the 4 cars needed.
