Answer:
30
Step-by-step explanation:
z(z-7)
Let z= 10
10(10-7)
Parentheses first
10 (3)
Multiply
30
In order to find the value first multiply both sides by 100 to simplify the equation:
0.05w*100=15*100
5w=1500
Next, divide both sides of the equation by 5:
5w/5=1500/5
w=300
The final solution is w=300!
Hope i could help.
have a great day
Answer:
7/3
Step-by-step explanation:
Simplify the following:
(1 + 3/4) (1 + 1/3)
Hint: | Put the fractions in 1 + 1/3 over a common denominator.
Put 1 + 1/3 over the common denominator 3. 1 + 1/3 = 3/3 + 1/3:
(1 + 3/4) 3/3 + 1/3
Hint: | Add the fractions over a common denominator to a single fraction.
3/3 + 1/3 = (3 + 1)/3:
(1 + 3/4) (3 + 1)/3
Hint: | Evaluate 3 + 1.
3 + 1 = 4:
(1 + 3/4)×4/3
Hint: | Put the fractions in 1 + 3/4 over a common denominator.
Put 1 + 3/4 over the common denominator 4. 1 + 3/4 = 4/4 + 3/4:
4/3 4/4 + 3/4
Hint: | Add the fractions over a common denominator to a single fraction.
4/4 + 3/4 = (4 + 3)/4:
4/3 (4 + 3)/4
Hint: | Evaluate 4 + 3.
4 + 3 = 7:
7/4×4/3
Hint: | Express 7/4×4/3 as a single fraction.
7/4×4/3 = (7×4)/(4×3):
(7×4)/(4×3)
Hint: | Cancel common terms in the numerator and denominator of (7×4)/(4×3).
(7×4)/(4×3) = 4/4×7/3 = 7/3:
Answer: 7/3
Answer:
b=5V2
Step-by-step explanation:
Area =31 1/4 = b*12.5 sin45/2=b*12.5*V2/2* 1/2=12.5V2/4 *b
(31*4+1)/4=125/4
so 125/4= 12.5V2*b/4
12.5V2*b=125
b=125/12.5V2=10/V2=10V2/2=5V2
