Answer:
m = 21 inches
The model length is 21 inches
Question;
Use the scale factor 1:12 to find the missing dimension. Great white shark actually lengthy 21ft. Find the model length in inches.
Step-by-step explanation:
Given;
Scale factor = 1:12
Actual length a = 21 ft
Let m represent the model length;
The ratio of model length to actually length is given as;
m/a = 1/12
m = a/12
Substituting a=21 ft;
m = 21/12 ft
Converting to inches;
1 ft = 12 inches
So,
m = 21/12 ft × 12 inches/ft
m = 21 inches
The model length is 21 inches
it would take them 5 hours and 70 seconds

Answer:
(1/2,4)
Step-by-step explanation:
First, determine y in first equation: 2x+y=5 or y=5-2x
replace value of y determined in first equation (5-2x) into 2nd equation
4x-3(5-2x)=-10
4x-15+6x=10
10x=5
x=1/2
put value of x into either equation to solve for y so
2(1/2)+y=5
1+y=5
y=4
answer: x=1/2, y=4
check answer by substituting x and y into either equation:
4x-3y=-10
4(1/2)-3(4)=-10
2-12=-10
-10=-10
or
2x+y=5
2(1/2)+4=5
1+4=5
5=5
