Jill bikes 2/3 hour at 18 mph and then walks 2/5 hour at 5 mph. How much farther did she bike than walk?

Oksana_A [137]

Answer:

Step-by-step explanation:

When the equation says that Jill bikes 2/3 hour at 18 mph, it means that the amount of miles she biked is 2/3 of 18. 18 divided by 3 is 6. 6 times 2 is 12, so she biked 12 miles. If she walks 2/5 hour at 5 mph, then she walked 2 miles because 5 divided by 5 is 1 and 1 times 2 is two. The question is asking how much more she biked than walked, so 12-2=10.

What percent of 300 is 51

Gnoma [55]

Answer:

Step-by-step explanation:

300:51*100 =

(300*100):51 =

30000:51 = 588.24

Now we have: 300 is what percent of 51 = 588.24

Question: 300 is what percent of 51?

Percentage solution with steps:

Step 1: We make the assumption that 51 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x.

Step 3: From step 1, it follows that $100\%=51$100%=51.

Step 4: In the same vein, $x\%=300$x%=300.

Step 5: This gives us a pair of simple equations:

$100\%=51(1)$100%=51(1).

$x\%=300(2)$x%=300(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{51}{300}$

100%

x%=

300

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{300}{51}$

100%=

300

$\Rightarrow x=588.24\%$⇒x=588.24%

Therefore, 17% of 300 is 51

Select from the matches below to correctly complete the statements. I'll give brainliest to someone with correct answer!

Aneli [31]

Answer:

<h3>The correct matches as follows :</h3>

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

3) The product of a linear monomial and a linear binomial - Quadratic binomial

Step-by-step explanation:

The correct matches as follows :

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

<h3> Monomial is a linear expression having only term with degree 1 (variable)</h3>

For Example : Let x and y be two monomials which is linear
If we product the two linear monomials we get
$x\times x=x^2$ which is a quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

<h3>For example : Let $x^2$ be the Quadratic monomial has one term with degree 2 and $x^2+2x+3$ be the quadratic trinomial ( has 3 terms with degree) </h3>
