Answer: 27.80
Step-by-step explanation:
(3/5) x 14 = 8.4
That's 4 of the 2 kilogram tubs and 1 of the 1 kilogram tub (gives 9 kilograms)
4 x 6.15 = 24.60
1 x 3.20 = 3.20
24.60 + 3.20 = 27.80
Answer:
It means 3 times pi (π) or 3 times 3.14159...
Step-by-step explanation:
if a number/value is directly next to another number/value, then that means that you're multiplying. Example: 3x or 3(5). Hope this makes sense and good luck on your assignment.
Answer:
81.25%
Step-by-step explanation:
Given that :
Engine power = 240 hp
Power delivered to drive wheel = 195 hp
Efficiency = (power delivered to drive wheel / Engine power) * 100%
Efficiency = (195 / 240) * 100%
Efficiency = 0.8125 * 100%
Efficiency = 81.25%
The efficiency of transmission and drive mechanism is 81.25%
Answer:
∠M=85 the shortest side is segment LM
Step-by-step explanation:
To figure out ∠m you need to add all of the angles together and make them equal 180.
(2x+5)+(3x+10)+(x+15)=180 Set the angles up to 180
6x+30=180 Combind like terms
6x=150 Subtract 30 from both sides
x=25 Divide by 6
Now you take x and plug it into ∠M
3x+10 The equation for angle M
3(25)+10 Add x into the equation
75+10 Multiply 3 by 25
85 Add 10
85=∠M
This is angle M. Now you have to do this for the rest of the of the angles.
2x+5 The equation for angle L
2(25)+ 5 Add x into the equation
50+5 Multiply 2 by 25
55 Add 5
55=∠L
x+15 The equation for angle N
(25)+15 Add x into the equation
25+15 Add 15
40
40=∠N
Answer:
B. f(x) = -x + 11
Step-by-step explanation:
First if you rearrange the equation you get f(x) = -x + 11, like this:
x + y = 11
Minus x from both sides
y = -x + 11
F(x) and y are interchangeable so we just put f(x) in
f(x) = -x + 11
Each of the graphs are attached and we see that they are the same!
