a = 10, c = 15, b = 5√5

a = 8, c = 18, b = 2√65

a = 12, c = 14, b = 2√13

a = 4, c = 20, b = 8√6

a = 12, b = 14, c = 2√85

a = 4, b = 20, c = 4√26

a = 10, b = 15, c = 5√13

a = 8, b = 18, c = 2√97

There are 3 girls and 4 boys in the Reese's family. Mr Reese's booth 6 1/2 pounds of candy. How much will each kid get

Sloan [31]

Answer:

Each Child get = 0.928 pounds of candy

Step-by-step explanation:

Total no of girls are 3

total no of boys are 4

Total no boys and girls are = 3 + 4

= 7

Now it is given that Mr Reese booth have some pound of candies and he wants to distribute it equally among each children

total candy Mr Reese have is $6\frac{1}{2}$

Now converting it to proper fraction

$6\frac{1}{2}$ = $\frac{6*2+1}{2}$

= $\frac{13}{2}$

Now the amount of candy have = $\frac{13}{2}$

Now we have to divide it into 7 kids

each kid get = total candy / total children

= $\frac{13}{2}$ ÷7

Changing the divide sign to multiplication

$=\frac{13}{2}*\frac{1}{7}$

Which becomes

$=\frac{13}{14}$

solving it gives

Each Child get = 0.928 pounds of candy

Answer:

The equation of the elipse is

$\frac{x^2}{169} + \frac{y^2}{25} = 1$

Step-by-step explanation:

Equation of an elipse:

The equation of a elipse with centre $(x_c,y_c)$ has the following format:

$\frac{(x - x_c)^2}{a^2} + \frac{(y - y_c)^2}{b^2} = 1$

Centre at (0,0):

Means that $(x_c,y_c) = (0,0)$ .

$\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1$

Vertex at (13,0):

Vertex at 13 means that $a = 13, a^2 = 13^2 = 169$

Focus at (-12,0):

Means that $c = 12, c^2 = 12^2 = 144$

We have that:

$a^2 = b^2 + c^2$

$169 = b^2 + 144$

$b^2 = 25$

So, the equation of the elipse is

$\frac{x^2}{169} + \frac{y^2}{25} = 1$

It took Marty 10 seconds to walk 15 feet. How fast was he walking in feet per second. Answer with supporting work

lozanna [386]

10 seconds = 15 feet
We want a measure of feet per second. (If seconds = 1, feet = ?)
Let's divide both sides by 10. (division prop. of equality)
1 second = 1.5 feet
1.5 ft/s
