A right angles has 2 sides 157 and 168 what is the other length
just olya [345]

Step-by-step explanation:

we can find the length of other side by hypotenuse formula,

which is h² = a² + b²

so,

a = 157

b = 168

now after inserting the values we got,

→ h² = (157)² + (168)²

→ h = 24649 + 28224

→ h = 52,873

→ h² = √52873 = 229.94

so, length of other side is 229.94

A cylindrical can of cat food has a diameter of 3.5 inches and a height of 1.25 inches A second brand of cat food is packaged in
UNO [17]
So..Volume of a cylinder = pi(r)^2 x Height
The first can has a radius of 1.75 (3.5/2) and a height of 1.25 inches..put that in the formula and you'll get the volume of the first cylinder ~ 12.02 
Do the same thing with the second cylinder and you'll get ~5.65 as the volume. 
Now calculate the difference between the two by simply subtracting the two volumes and the difference would  approximately be 6.37 
hope this helps! :)

The low temperature last week in Iceland was-2.25. The low temperature this week was 1.25. What was the change in temperature fr
viktelen [127]

Answer:

The change in temperature from last week to this week=3.5

Step-by-step explanation:

To get the change in temperature from last week to this week, we need to take last week's temperature and subtract it from this week's temperature.

For example;

Change in temperature=This week's temperature-last week's temperature

where;

This week's temperature=-2.25

last week's temperature=1.25

replacing;

Change in temperature=(1.25)-(-2.25)=1.25+2.25=3.5

The change in temperature from last week to this week=3.5

Please help me with these. <br> Thanks
DIA [1.3K]
5.

f(K) = D^3 => f(25) = 125 => 25 * t = 125 ( because K is directly proportional with D^3 )=> t = 125 / 25 => t = 5 => f(25) = 25 * 5 => K * 5 = D^3 ;

6. 

f(L) = F^3 => f(2) =3^3 =>f(2) = 27 => 2 / t =27 => t = 2 / 27 => t = 0.074 => f(2) = 2 / 0.074 => K / 0.074 = F^3 ;

Write the series using summation notation. Then find the sum of the series.
ivolga24 [154]

Hello, please consider the following.

\displaystyle 1+2+3+...+12=\sum_{k=1}^{k=12} {k}=\dfrac{12*13}{2}=6*13=78

For the second we will need to put on the same denominator.

\displaystyle \dfrac{1}{2}+\dfrac{1}{4}+...+\dfrac{1}{14}=\sum_{k=1}^{k=7} {\dfrac{1}{2k}}\\\\=\dfrac{1}{2}\dfrac{420+210+140+105+84+70+60}{5*7*3*2*2}\\\\=\dfrac{1}{2}\dfrac{1089}{420}\\\\=\dfrac{1089}{840}=1.296429...

Thank you.
