Negative 1 times the square root of 61 is -7.81
A. An integer is a whole number without decimals
If this is rounded to the nearest integer, the number is -8
B. Rounded to the nearest tenth is the first decimal place. Therefore the number would be -7.8.
Answer:
The perimeter of the triangle 198 cm.
Step-by-step explanation:
Given that,
In a right angled triangle, a and b are the length of the legs and c is length of the hypotenuse.
Pythagorean Theorem:
Sum of square of the legs is equal to square of hypotenuse.
∴a²+b²=c²
a= ?, b= 77 cm and c=85 cm
a²+77²=85²
⇒a²+5929=7225
⇒a²=7225-5929
⇒a²= 1296
⇒a = 36 cm
The perimeter of the triangle = sum of all sides
=a+b+c
=(36+77+85) cm
= 198 cm
Answer:
24
Step-by-step explanation:
The multiples of 8 are 8,16,24,32 etc. and the multiples of 6 are 6,12,18,24,30, ect. The answer is 24 because it is the lowest multiple of 6 that crosses with multiples of 8.
-2 degrees because 4 times -3 is -12 and 10-12 is -2
we are given
The scale is
the distance from Happy Hill Park to Rainbow Valley Park is 4 1/2 inches
we can change it into rational form
and we get
so, we can multiply both sides by 9
now, we can simplify it
so, the actual distance between the two parks is 27 miles........Answer
