Answer:

∠ B ≈ 66.42°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos B = $\frac{adjacent}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{2}{5}$ , thus

B = $cos^{-1}$ ( $\frac{2}{5}$ ) ≈ 66.42° ( to the nearest hundredth )

1.2x + 3 =4x + 2

Dmitry_Shevchenko [17]

1. 2x+3=4x+2
⇒ 4x-2x=3-2
2x=1
x=1/2
There is one solution.

2. 18p-10p=5+6/2
8p=5+3
8p=8
p=8:8
p=1

3. 6a/3=2a
2a-a= -2 -3
a= - 5

4. 5+r-2=9,
5-2+r=9
3+r=9
r=9 - 3
r=6

5. -0,9 m= 9
m= - 10

6. -2 (x+1/4)=5-1=4
x+1/4= -2
x= -2 - 1/4
x= -8/4 - 1/4= - 9/4

7. 6f+4f= 6 + 12
10 f = 18
f=18/10=1,8

8. 7n - 3n= 16
4n=16
n=16:4
n=4

9. 1/3m-5/6m= - 15 - 3
2/6 m-5/6=-18
- 3/6m=-18 ⇒ 1/2m=18
m=2*18=36

10. A 266-hp output is required for an engine. If there is a 5% loss of power, what amount of input

marta [7]

Answer:

Amount of input horsepower needed is 279.3 hp.

Step-by-step explanation:

if there is a loss of power of 5% the base horsepower will need to be increased by same percentage so that same amount of power can be delivered.

Now to calculate 5% of 266 hp, we can write

266 × $\frac{5}{100}$ = 13.3 hp
