Answer:
Scale Factor states that the ratio that you get when you divide corresponding side lengths of similar figures.
Given: Triangle ABC is congruent to Triangle DEF.
Similar figures have corresponding angles that are equal and corresponding sides that are equal.
To find the scale factor,
you need to find the ratio between the corresponding sides of the triangle.
now, you can multiply each side of one triangle by the same number to get the sides of the other triangle.
∴ The number is the scale factor, that is what we are trying to find.
That means he had 400 or 4000mm
Answer:
y=7600(5^(t/22))
Step-by-step explanation:
This is going to be an exponential function as it grows rapidly.
This type of question can be solved using the formula y=a(r^x), where a is the inital amount, r the factor by which the amount increases and x is the unit of time after which the amount increases.
x=t/22
a=7600
r=5
∴y=7600(5^(t/22))
Answer:
10°
Step-by-step explanation:
the sum of interior angles of triangle is 180°
so. 8x+x+90°=180°
9x=90°
x=10°
