Answer:
7√5
------- or (7/5)√5
5
Step-by-step explanation:
7√100
---------- can be simplified by reducing the radicand from 100/500 to 1/5.
√500
Then we have 7
------
√5
Multiplying numerator and denominator both by √5 results in
7√5
------- or (7/5)√5
5
Answer:
A = 21.2
Step-by-step explanation:
Assuming that the triangle is equilateral, the area would be approximately 21.2 feet.
Answer:
121 sweets
Step-by-step explanation:
David is the first 4 in the ratio 4:3:4. We know that David gets 44 sweets. We also know that Paul gets 44 sweets because he is the other 4 in the ratio. To find out how many sweets 3 is equal to, you need to find the unit rate. To do this, you can divide 44 by 4 to know how much 1 equals. When you divide 44/4, you get 11. This means that 1 is 11. To find out what three is, you can multiply 11 by 3 to get 33. The question asks how many sweets are there altogether, so you must add 44+33+44. This equals 121.
The central angle measure of the sector is 4.19 rad.
<h3>Area of a Sector</h3>
You need apply the formula: for finding the area of the sector, in radians. In this formula, the variables are:
r= radius
= central angle
The question gives:
A=54 cm²
r= radius= 9cm
Thus, the central angle will be:
For =3.14159..., you have :
