Answer:
The answer is A. This is because 2.50 times 5 is 12.50. 12.50 added with the photography monthly bill of $15 equals 27.50.
If this helped let me know! Have a great day! :)
Answer:
Im assuming you are trying to convert scientific notation to a number. In that case 1.18 x 10 to the third power would be 1,180 and 9.1 x 10 to the -6 would be .0000091.
Hope this helps!
Step-by-step explanation:
The perimeter of a triangle is given by:
Perimeter = sum of three sides
We are given perimeter = 112 in.
Hypotenuse = 50 in.
Let us say the other two sides are a and b.
So , we have
...............(2)
In a right angle triangle we can apply pythagorean theorem,
a² + b² = c²
here c is hypotenuse which is 50 in.
a²+b² = 50²
a²+b² = 2500............(2)
Plugging the value of a from equation (1) in (2)
Factorising ,
So we have two values of b
b=14 and b=48
If b=14, a=48
If b=48, a=14
Answer: The shorter leg will be 14 inches.
Answer:
x= 18
y =45
Step-by-step explanation:
first these two angles are supplementary and add up to 180 degrees:
(6x+7) + (4x-7) = 180
find x:
10x = 180
x = 18
substitute x = 18 for the angle (6x+7)
now we know what 6x +7 =
6 (18) + 7 = 115
since angle 3y-20 = 115, solve for y
3y = 135
y = 45
Answer:
B=50
Step-by-step explanation:
THE TRINGLE IS 180 DEGREE (RULE)
(X+38)+(3X-12)+(2X-2)=180
6X=180-(38-12-2)
6X=156
X=26
B=2X-2
B=2(26)-2=52-2=50
