\text{Hey there!}

\text{Percentages usually run out of 100}

\dfrac{21}{25}\ = \ 21\div25\ = \ 0.84

\huge\text{Decimal form: 0.84}

\text{Remember what I said, percentages run out 100. ( e.g. x * 100)}

\text{0.84\% }\times\text{ 100 = 84\%}

\boxed{\boxed{\huge\text{Answer: 84\%}}}\huge\checkmark

\text{Good luck on your assignment and enjoy your day!}

For this case we must write as a percentage the following expression:

\frac {21} {25}

Dividing we have to:

\frac {21} {25} = 0.84

Now we multiply by 100%. So:

0.84 * 100 =

We run the decimal two spaces to the right, finally we have:

84%

Answer:

84%

Solve the system of equations by graphing. Check your solution.<br><br> 5x+y=14<br> 2x-y=7
Fudgin [204]
ANSWER

(3,-1)

EXPLANATION

The given system of equations is :

5x+y=14

2x-y=7

For the first equation when x=0,

5(0)+y=14

y=14

The y-intercept is (0,14).

When y=0, 5x+0=14

x = \frac{14}{5} = 2 .8

The x-intercept is (2.8,0).

We plot the intercepts and draw a straight line through them to obtain the graph of 5x+y=14 as shown in the attachment.

We repeat the same process for the second equation 2x-y=7.

The intercepts are (0,-7) and (3.5,0)

The solution to the system is the point of intersection of the two straight lines.

The two straight lines intersected at

(3,-1)

Hence x=2, y=-1

I really need help guys can some one plz help me it's for 10 points

Answer:

\sqrt{8}----- 2units,2units

\sqrt{7} ------\sqrt{5}units,\sqrt{2}units

\sqrt{5}-------1unit,2units

3------2units, \sqrt{5}units

Step-by-step explanation:

Use pythagorean's theorem to solve each pair individually.

The instructions say that you have the two sides (a and b) and you have to match it with their hypothenuse.

Formula: c^2=a^2+b^2

1. a=\sqrt{5}, b=\sqrt{2}

Plug this into the formula.

c=\sqrt{(\sqrt{5} )^2+(\sqrt{2})^2 }

The square here eliminates the roots.

c=\sqrt{5+2}\\ c=\sqrt{7}

2. a=\sqrt{3}, b=4

c=\sqrt{(\sqrt{3} )^2+(4)^2}\\ c=\sqrt{3+16}\\ c=\sqrt{19}

3. a=2, b=\sqrt{5}

c=\sqrt{(2)^2+(\sqrt{5})^2 }\\ c=\sqrt{4+5}\\ c=\sqrt{9}\\ c=3

4. a=2, b=2

c=\sqrt{(2)^2+(2)^2}\\ c=\sqrt{4+4}\\ c=\sqrt{8}

5. a=1, b=2

c=\sqrt{(1)^2+(2)^2}\\ c=\sqrt{1+4}\\ c=\sqrt{5}

Three of the four golfers 1 L of water. The fourth golfer drinks 1.5 L of water. How many milliliters of water did the group dri
elena55 [62]
Well, 1 Liter plus 1.5 Liters equals 2.5 Liters. We know that milli means 1000, so there are 1000 milliliters in a liters, so, all we have to do is multiply 2.5 liters by 1000 to get 2,500 milliliters!
