Answer:
we know all angles are 90° in the rectangle
therefore, angle d = bdc+bda = 90
=> 31+bda = 90
=>angle bda= 59
Answer:
Length between the longest bolt and the shortest bolt is:
2.375 inch
If we laid one of each size bolt end to end , then the length of row of bolts is:
5.125 inch
Step-by-step explanation:
We are given that:
Martin sorted the bolts in his toolbox by size.
They measured 3/8 inch, 1/2 inch,5/8 inch, 7/8 inch, and 1 1/4 inches
longest bolt= 11/4 inches shortest bolt=3/8 inch
Difference between longest and shortest bolt= 
Now, if we lay one of each size bolt end to end then, length of row will be:

=41/8
= 5.125 inches
Divide the arrow into upper triangle and lower rectangle
area of triangle :-


area of rectangle :-

add both the area :-
area of triangle+ area of rectangle = area of arrow
310 + 300 = 610 cm²
Answer:
Rational number
Step-by-step explanation:
Any number that can be written as a ratio of two integers is a rational number.
In the question, you have the keyword 'ratio', meaning a comparison between two numbers. For example 1.5 can be expressed as the ratio between 3 and 2 (3/2), as a fraction.
<u>When a number cannot be expressed as a fraction, it's called an irrational </u>number. <u> The most famous irrational number of all would be pi (π). </u> You cannot express pi in a ratio between numbers, because it's too complicated, it's basically an infinite number without any periodicity.
