Answer:

10 meters in 1 second

Step-by-step explanation:

10*100=1000m=1km in 1*100seconds

Hence for 6km, it will take 6*100=600 seconds

Which is =10 min

[tex]\bold{1.66 \: is \: the \: speed \: of \: the \: school \: bus. }[/tex]

Step-by-step explanation:

Formula :-

[tex]s = \frac{distance}{time} [/tex]

Therefore :-

[tex] \longmapsto [/tex] [tex]s = \frac{100}{60} [/tex]

[tex] \longmapsto [/tex] [tex]s = \frac{10}{6} [/tex]

[tex] \longmapsto [/tex] [tex]s = 1.66[/tex]

Speed = 1.66 is the answer.

[tex]\\ \tt\hookrightarrow Speed=Distance/Time[/tex]

[tex]\\ \tt\hookrightarrow Distance=Speed\times Time[/tex]

[tex]\\ \tt\hookrightarrow Distance=30(10.5)[/tex]

[tex]\\ \tt\hookrightarrow Distance=315km[/tex]

First, let's organize the equations of the lines into slope-intercept form.

And,

Since both the graphs are the same, the two equations have infinitely many solutions.

Answer:

Step-by-step explanation:

Hello!

When given an equation y=mx+b, m stands for the slope and b stands for the y-intercept. The y-intercept tells us that even if we start on the x value 0, whatever is the y-intercept will be our answer.

For this equation, the 20 does not represent per hour rental, as it should be the slope if it was. The total cost is not true either, 20 would be placed where the Y is.

It is A, since no matter how many hours you rent the kayak, it will still be a 20 dollar deposit.

Hence, the value of s must be 35 units so that the quadrilateral becomes a parallelogram.

keeping in mind that a function doesn't have any X-repeats, namely the x-coordinate of every pair must not repeat, Check the picture below.

Answer:

Given :0.2x + 0.3y = 1.3

0.4x + 0.5y = 2.3

To Find solve using substitution method

Solution :

0.2x + 0.3y = 1.3

0.4x + 0.5y = 2.3 -2

Substitute the value of x from 1 in 2

0.4(1.3-0.3) +0.5y = 2.3

y = 3

0.2x + 0.3(3) = 1.3

0.2x = 1.3 0.9

X = 1.3-0.9 0.2

x = 2

So, x = 2 and y = 3

Answer:

[tex]y=5[/tex]

Step-by-step explanation:

[tex]8-1.2y=2[/tex]

Subtract 8 from both sides.

[tex]-1.2y=2-8[/tex]

Subtract 8 from 2 to get -6.

[tex]-1.2y=-6[/tex]

Divide both sides by -1.2.

y= [tex]\frac{-6}{-1.2}[/tex]

Expand [tex]\frac{-6}{-1.2}[/tex] by multiplying both numerator and the denominator by 10.

[tex]y=\frac{-60}{-12}[/tex]

Divide -60 by -12 to get 5.

[tex]y=5[/tex]

Answer:

60

Step-by-step explanation:

Start by identifying the part (48) and the percentage (80%). If you know these two values, you can find the whole.

By replacing the given values in the formula, you get:

80 = 48

100 whole

Now cross-multiply:

80 × whole = 48 × 100

Then, divide both sides by 80 and get the whole:

whole = 48 × 100  = 60

80

One step:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 48 is 80% of = 48 × 100  = 60

80

Note: most values are rounded to 10 digits.

Answer:

1) 105.5    2) 67,994,000    3) -4.1

Step-by-step explanation:

The place value after the decimal point goes 10th, 100th, 1000th, etc.

For #1, we're asked to round to the nearest 10th. The 10th value is 4. To round it to the nearest 10th, we have to look at the number after that. In this case, it's 9. Since 9 is bigger than 4, the 4 becomes a 5, and all the other decimal points become 0. So, 105.496 rounded to the nearest 10th is 105.5

For #2, we're asked to round to the nearest 10,000s. The 10,000s value in 67,994,374 is 9. The value after that is 4. Since 4 is less than 5, the 4 stays the same but all the other values become 0. So, 67,994,374 rounded to the nearest 10,000s is 67,994,000.

For #3, we're asked to round to the nearest 10th. The 10th value is 0. To round it, the value after that is 5. 5 is equal to five, which means the 0 turns 1, and the other values become 0. So -4.05 rounded to the nearest 10th is -4.1

Step-by-step explanation:

I just answered that. how often did you put that in ?

Answer:

Exponential function: a*b^x

if B is less than 1, it is a decay function

if B is more than 1, then it is a growth function  

if B is 0, then the function neither decreases nor increases

Example 1: 100*0.14^x

The y-intercept is decreasing by 86%

Example 2: 3000*1.14^x

The y-intercept is increasing by 14%

Example 3: 400*0

The y-intercept is neither decreasing nor increasing

Going back to the function, a is the y-intercept, and b is the rate

I hope this will help you, I just started to learn about exponential functions..

Answer:

  (b)  √5

Step-by-step explanation:

The square root of an integer is rational if the integer is a perfect square. You probably know the first few perfect square integers are 1, 4, 9, 16, 25, 36, ...

The integer 5 is not on that list, so its square root will be irrational.

  √5 is irrational

Your welcome

The average rate of change for the function f(x)= 3^x + 25 using the intervals of x=2 to x=6 is 6.75

The function is given as:

f(x) = 3^x + 25

The interval is given as:

x = 2 to 6

Start by calculating f(2) and f(6)

f(2) = 3^2 + 25 = 34

f(6) = 6^2 + 25 = 61

The average rate of change is then calculated as:

[tex]m = \frac{f(6) - f(2)}{6 -2}[/tex]

This gives

[tex]m = \frac{61 - 34}{6 -2}[/tex]

[tex]m = \frac{27}{4}[/tex]

m = 6.75

Hence, the average rate of change is 6.75

Step-by-step explanation:

The largest number she uses for a random number is 100. The smallest is one.

A wand comes up 47% of the time. Since it is the most common event, you could put it first and let the range be 1 to 47 inclusive.

But any range will work as long as there are 47 numbers between the beginning and the end, like 30 and 77. This looks like it won't work, but it will. It's just a little awkward. One of the other 2 might have to be split.

The Amulet can go from 78 to 100 which takes up 22 numbers. The other 13 can go before the 30
