4 miles
Step-by-step explanation:
if you travel 8 in 1 hour just cut it in half
8 * 1/2 = 4
Answer:
374
Step-by-step explanation:
11/50=0.22
number/1700=0.22
so 374/1700=0.22 hope that's a choice and helps.
"31-inch piece of steel is cut into three pieces"
Call the pieces a,b,c
a + b + c = 31
"second piece is twice as long as the first piece"
b = 2a
"third piece is one inch more than seven times the length of the first piece"
c = 1 + 7a
Ok, we have our equations, let's substitute the second and third into the first.
a + 2a + 1 + 7a = 31
10a + 1 = 31
10a = 30
a = 30/10 = 3
b = 2a = 6
c = 1 + 7a = 22
Check: 3 + 6 + 22 = 31, good
Answer: 3 inches, 6 inches, 22 inches
Answer:
The value of x is 12.1
Step-by-step explanation:
To find the value of x, we will just apply the formula of trigonometric ratio;
SOH CAH TOA
sin Ф = opposite/ hypotenuse
cos Ф = adjacent / hypotenuse
tan Ф = opposite / adjacent
From the diagram given, since we are working with angle 48 then opposite is 9 and hypotenuse is x
Ф =48° opposite = 9 and hypotenuse = x
The best formula to use is;
sin Ф = opposite/ hypotenuse
sin 48° = 
cross-multiply
x sin 48° = 9
Divide both-side by sin 48°
x sin 48° / sin 48° = 9/sin48°
x = 9/sin 48°
=12.11069
x ≈12.1 to the nearest tenth
Therefore the value of x is 12.1
