Find the lenght of the unknown side. Round it to the nearest tenth
A.9.4 m
B.88 m
C.15.8 m
D.4 m

Answer:

7 hours and 30 minutes

Step-by-step explanation:

[tex]240 \div 4 = 60km \: per \: h[/tex]

[tex]450 \div 60 = 7.5 = 7h \: 30min[/tex]

It will take motor bike 7.5 hours to cover 450 Km of distance.

Speed of a body is defined as the distance travelled by it per unit time taken to cover the distance.

Mathematically-

S = Δd/Δt  or   S = {d(2) - d(1)}/{t(2) - t(1)}

It is a scalar quantity as it only has magnitude and no direction.

Given is a motor bike travels 240 km ins 4 hours.

We can calculate the speed of the bike as -

s = 240/4 = 60 Km/hr

Then, the time taken to cover 450 Km will be -

t = 450/60

t = 7.5 hours

Therefore, it will take motor bike 7.5 hours to cover 450 Km of distance.

Answer: They are both correct

Step-by-step explanation:

Jane saying 5 is a factor for every while number that has a 5 in the ones place is correct. For example, in the number 345 or 25, we can see that we have 5 in the ones place and 5 is a common factor for the numbers.

Also, Fred saying 5 is a factor for every while number that has a 0 in the ones place is correct as well. For example, the numbers 10, 20, and 200 all have 0 in their ones place and they have a factor of 5 as well.

Therefore, both of them are correct.

Answer:

1 i believe or 2

Step-by-step explanation:

you must change the denominator so they both equal the same and then find out how many times 2/3s are in 9/8

Answer:

3/4

Step-by-step explanation:

We first need to have these two as a common denominator.

We can multiply 3 by 4 to get 12 as our denominator, which matches both denominators.

5/12 + 1*4/3*4 =

5/12 + 4/12 =

(5+4)/12 =

9/12

We can simplify further by diving by 3, which would give us 3/4.

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

Let's say that the number is x. Hedi adds 5 to the number, then multiplies its sum by -2. The result is 6. Writing this out as an equation:

[tex]-2(x+5)=6[/tex]

So now we solve for x. First, we divide both sides by -2, giving us:

[tex]x+5 = -3[/tex]

Then, to finish the problem, we subtract 5 from both sides:

[tex]x=-8[/tex]

Thus, the number Hedi started with was -8

Step-by-step explanation:

To find the Slope of each line, pick two points you can clearly identify on each graph. The first graph has a point (-5,5) and (4,-5). Using these two points find the difference of the y coordinates divided by the difference in the x coordinates, like this:

5 - (-5). = 10

-5 - 4 = - 9

So the Slope is - 10/9

Finding the degree of a polynomial is really simple. All you have to do is find the largest exponent in the polynomial, so in this case, the degree is 5 (Yes, my previous answer is wrong) and not 26. I don't know how you got 26.

Another example: In 3x² - 8x⁷ + 6xy⁴, the degree is 7.
