Answer:
8
Step-by-step explanation:
i don't see options to select from but my guess would be 8 because 7/8 is very close to being one and 8 1/10 is close to 8; 8 x 1 = 8
<h2>
Answer:</h2>
is 3 ohms
<h2>
Step-by-step explanation:</h2>
In a circuit containing two resistors
and
connected together in parallel, the total resistance
is given by;
---------(i)
<em>Make </em>
<em> subject of the formula;</em>
=>
=> ![\frac{1}{R_2} = \frac{R_1 - R_T}{R_TR_1}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_2%7D%20%3D%20%5Cfrac%7BR_1%20-%20R_T%7D%7BR_TR_1%7D)
=>
---------------(ii)
From the question,
= 6Ω
= 2Ω
Substitute these values into equation (ii) as follows;
=> ![{R_2} = \frac{2*6}{6 - 2}](https://tex.z-dn.net/?f=%7BR_2%7D%20%3D%20%5Cfrac%7B2%2A6%7D%7B6%20-%202%7D)
![{R_2} = \frac{12}{4}](https://tex.z-dn.net/?f=%7BR_2%7D%20%3D%20%5Cfrac%7B12%7D%7B4%7D)
= 3Ω
Therefore, the value of
= 3 ohms or
= 3Ω
Answer:
1.5.80 miles
2.9.80ft
3.56 inches
4.5.20 units
5. 13 units
6.5.40 ft
Step-by-step explanation:
⇒These questions are on the Pythagorean relationship
⇒General expression is ;
a²+b²=c² where a and b are values for the legs and c is the hypotenuse
1. Isaiah waked 3 miles north and 5 miles east.
Finding the distance from starting point we apply the equation;
a²+b²=c² where a=5 miles and b=3miles
5²+3²=c²
25+9=c²
34=c²
c=√34 = 5.80 miles
2.The ladder is leaning against the wall to form the hypotenuse side of 10 ft.The distance from the base to the ladder forms side a= 2ft. The question requires you to calculate the height b.
a²+b²=c²
2²+b²=10²
4+b²=100
b²=100-4
b=√96
b=9.80 ft
3. The television has a diagonal of 70 inches to represent side c and a height of 42 inches to represent the side a. The question requires you to find the width of the television which represents the side b
a²+ b²=c²
42²+b²=70²
b²=70²-42²
b=√3136
c=56 inches
4. An equilateral triangle is one that has all its sides and angles equal. Here you have to introduce a perpendicular line from the apex point of the triangle to the base and get the distance a.The using the hypotenuse and the distance a, you can find the height/b.
c= 6 units and a=6/2= 3 units
a²+b²=c² 3²+ b²= 6²
9+b²=36
b²=36-9
b=√27 =5.20 units
5.In this question, you are given the height and the width of the right triangle thus apply the relationship as;
a²+b²=c²..........where a=5 and b=12
5²+12²=c²
25+144=c²⇒⇒⇒c=√169 =13 units
6. In this question, the height of the plant represents side b and the distance of the base from where the string is tied is side b.You are to find the length of the string which represents the hypotenuse side.
a²+b²=c²
5²+2²=c²
25+4=c²
29=c²
√29=c
c=5.40 ft
