Answer:
Your answer is 15.2
Step-by-step explanation:
use the formula a² + b² = c²
In this case, you know what a and c are.
a = 13
c = 20
Put those two into the formula.
13² + b² = 20²
13² = 169
20² = 400
169 + b² = 400
Bring 169 over to the other side to get b² by itself. do this by subtracting it from 400.
400 - 169 = 231
b² = 231
Now we need to get rid of the exponent. To do this, get the square root of both sides.
√b² = √231
b = 15.1986841536...
Finally, round your answer to the nearest tenth like the question tells you to.
15.2
Therefore:
b = 15.2
6.32ft per inch (rounded to the hundredth place).
You can get this number by dividing the total number of feet by the total number of inches
X - y < 0....so sub in ur answer choices to see which one makes the inequality true
subbing in (-2,0)
-2 - 0 < 0
-2 < 0 (true)
so ur answer is (-2,0)
Answer:
1.5
Step-by-step explanation:
a : b = 1 : 12/5
Area of a circle = πr²
Where : = π = pi = 22/7
R = radius
Let the radius of circle a = 1
Area of circle A = 1π
Radius of circle A = square root of 12/5 = 1.5
The circumference of a circle = 2nr
n = 3.14
circumference of circle A = 2 x n x 1 = 2n
circumference of circle B = 2 x n x 1.5 = 3n
ratio of circumference = 3n / 2n = 1.5
7/8(x-1/2)= -49/80
Multiply the bracket by 7/8
7/8x-7/16= -49/80
Move -7/16 to other side. Sign changes from -7/16 to +7/16
7/8x-7/16+7/16= -49/80+7/16
7/8x= -49/80+7/16
Find common denominator for 7/16 which is 5. Multiply 5 for the numerator and denominator.
7(5) / 16 (5)
= 35/80
7/8x= -49/80+35/80
7/8x= -14/80
Reduce -14/80 , divide by 2
(-14) /2=7 , 80/2= 40
-14/80= -7/40
7/8x= -7/40
Multiply by 8/7
7/8x*8/7= -7/40 * 8/7
Cross out 7 and 7 , and divide by 7. Cross out -7 and 7 and divide by 7. Cross out 40 and 8 divide by 8.
x= -1/5
Answer: x= -1/5 - G.
