Answer:
<u>The</u><u> </u><u>requ</u><u>ired</u><u> </u><u>num</u><u>ber</u><u> is</u><u> </u><u>7</u><u>0</u><u>.</u>
Step-by-step explanation:
let the no. be 10y + x where x is unit digit and y is ten's digit.
given , sum of the digit is 7
x + y = 7 ...(1)
also , reversing the no. we get 10x + y ,where x is ten's digit and y is unit digit.
given reversed digit decreases the number by 63 .
so, 10y + x - ( 10x + y ) = 63
9y -9x = 63
( dividing both side by 9 )
y - x = 7 ....(2)
adding 1 and 2 [ refer attachment ]
so the required original number is
10y + x = 10×7+0 = 70
Answer:
(f/g)(8)= f(8)/g(8)= = 65/41
Step-by-step explanation:
f(x)=3 - 2x
g(x)=1/x +5
The easiest approach is to eval first the point in every function before performing the division, thus we have that:
f(8)= 3-2*8=-13
g(8)=1/8 +5= 41/5
Now, (f/g)(8)= f(8)/g(8)= 13 / (41/5) = 65/41
Blaise Pascal (June 19, 1623 - August 19, 1662) was a great contributor to math, science, and philosophy, especially Christian philosophy. Interesting Blaise Pascal Facts: Pascal's early education in France was conducted at home by his father due to the prodigious talent and understanding he showed as a child. Did u mean pascal instead of pasical becaus ethere is no such thing. Hope I helped :)
Answer:
ST/XY
Step-by-step explanation:
(RT/RX)/(RS/RY)= ST/XY
if the shapes are equal and the same then the ratio are equal
if RT is corresponds to RX and RS is corresponds to RY then TS corresponds to TS
Answer:
17.32 meters
Step-by-step explanation:
We realize the cable is the hypotenuse and then that height would be the new side, the measurement would not change once hypotenuse is found.
60 deg is the lower angle as it meets the ground base.
Sin (60) = 0.8660254038 x 20 = 17.32m
0.86 reduction = a
We use Sin (60) = a a x 20 to find the pole as above.
We use Tan (60) x base to find 20m to check hypotenuse if base was given = length of floor x tan(60) etc.
