Answer:
a = 300
b = 150
c = 60
d = 30
e = 6
To find the answer:
One way is to put the percents into fractions simplest form and divide by 600.
So:
a = 1/2
b= 1/4
c = 1/10
d = 1/20
e = 1/100
Divide these by 600, you get the same answers.
-----------------------------------------------------------------------
The Advanced Way:
To find a percent, you (can) turn the percents into fractions and multiply the number from the fraction.
For example: Question A:
600 x 1/2 = 300
You get the same answers as the ordinary version too. From right above Advanced.
Have a great evening, good luck on your homework.
Answer:
1) 60°, 75°, 120°, 105°
2) 101.5 m
Step-by-step explanation:
1) The sum of ratio units is 4+5+8+7 = 24, which corresponds to the sum of angles, 360°. Then each ratio unit must stand for 360°/24 = 15°. Multiplying the given ratio units by 15° gives the angle measures:
- 4×15° = 60°
- 5×15° = 75°
- 8×15° = 120°
- 7×15° = 105°

2) The similarity statement and the scale factor mean ...
MJ : TQ = 4 : 7
7·MJ = 4·TQ . . . . . . . . . "cross multiply"
TQ = 7/4×MJ = 7/4(58 m) . . . . . divide by 4, substitute the value of MJ
TQ = 101.5 m
ANSWER
EXPLANATION
We want to factor:
completely.
Recall from binomial theorem that:
We make x³-y³ the subject to get:
We now factor the right hand side to get;
We factor further to get,
This finally simplifies to:
Answer:
<em>B. 74.89</em>
Step-by-step explanation:
sin(27) = 34/x
sin(27) → 0.45399049974 ≈ 0.45399
x = 34/0.45399
x = 74.89
Hope this helped! :)
