Henry has 15 lawns mowed out of 60 lawns. What percent of the lawns does Henry still have to mow?

1 answer:

8 0

Using is/of=%/100 15 lawns is what % of 60
15 over 60 = % over 100
Cross multiple and divide and you should get 25%
That percent means that 25% of the lawns are mowed, so 75%  of the lawns need to be mowed

Do the ratios 10:20 and 2:24 form a proportion?

expeople1 [14]

We have:

$10:20=\frac{10/10}{20/10}=\frac{1}{2} \\2:24=\frac{2/2}{24/2} =\frac{1}{12} \\=>\frac{1}{2}\neq \frac{1}{12}\\$

So: $10:20\neq 2:24$

ANSWER: No

Ok done. Thank to me :>

What is square root of 5x^4-6x^5+x^6+16x^3-8x^2-8x+4 ? help me pleasee !

Natali5045456 [20]

Answer:

y = (x + 1)(x - 0.586) ( x - 3.414)

Step-by-step explanation:

I sure wouldn't recommend doing this by trial and error.

I made a graph of which you can see. Every time this monster touches the x axis and speeds away upward is two equal roots of y. So the square root would be one of each of them.

y = (x + 1)^2 (x - 0.586)^2 (x - 3.414)^2

are the listed roots.

The square root is

y = (x + 1)(x - 0.586) ( x - 3.414)

Do I know that this is right? I don't. But I can tell you this: if you multiply 1^2 * (-0.586)^2 * (- 3.414)^2

you get 4 just as you should. Amazing that we have tools that do that sort of thing.

Klio2033 [76]

Answer:

x = 2x

x + 20 = 2x + 20

And,

1.5(x + 20) = 2x + 20

x = 20 i.e. Alexis

And, Jelani be 40

Step-by-step explanation:

Given that

Jelani has twice as much as Alexis

And, both can added $20

Jelani will have 1.5 times as much on his pass on Alexis

We need to write an equation also the amount does Jelani and Alexis have

So,

Let us assume the alexis be x

And, Jelani be 2x

Now

x = 2x

x + 20 = 2x + 20

And,

1.5(x + 20) = 2x + 20

1.5x + 30 = 2x + 20

-0.5x = -10

x = 20 i.e. Alexis

And, Jelani be 40

Wewaii [24]

Answer:

The question is incomplete, so I looked for similar ones and found:

Of the 25 girls on the Alden Middle School soccer team, 40% also play on a travel team. How many of the girls on the middle school team also play on a travel team?

we can solve this the following way:

25 girls on the soccer team x 40% that play on a travel team = 10 girls form the soccer team that play on a travel team

we can also multiply (25 girls x 40) / 100 = 10 girls

we can check our work by:

10 girls / 40% = 25 girls in total
