Step-by-step explanation:
The formula for the area of a triangle is . Since this square pyramid is essentially four triangles with base length 21.5 feet and height 13.4 feet, we can calculate the area that they take up with the formula
square feet. Hope this helps!
The wrong step is step 4, because you only need one conversion.
The formula to convers pounds to kilograms is
Obviously, the inverse formula is
So, you're given an input of 142 pounds. To convert it in kilograms, plug that value into out formula:
and this is the answer you're looking for, so you need no more steps.
Bella can cut 24 pieces of ribbon from this long strip
<u>Solution:</u>
Given that Bella has 85 feet of ribbons in total
She needs identical strips of ribbon measuring 3.5 feet each
To find: Number of peices of ribbon can she cut from long strip
Number of peices of ribbon can she cut from long strip can be calculated by dividing the total feet of ribbon she has by length of identical strips she needs
<em><u>Mathematically written as:</u></em>
Hence , the number of strip can be 24 each of size 3.5 feet
Answer:
Step-by-step explanation:
A direct variation equation is of the form
y = kx,
where, in words, it reads "y varies directly with x" or "y varies directly as x". In order to use this as a model, we have to have enough information to solve for k, the constant of variation. The constant of variation is kind of like the slope in a straight line. It rises or falls at a steady level; it is the rate of change.
We have that a vet gives a dose of three-fifths mg to a 30 pound dog. If the dose varies directly with the weight of the dog, then our equation is
d = kw and we need to find k in order to have the model for dosing the animals.
Divide both sides by 1/30 to get k alone.
and
Our model then is
This means that for every pound of weight, the dog will get one-fiftieth of a mg of medicine.
