Answer:
7 1/4 yards or 7.25 yards
Step-by-step explanation:
3+3=6
5/8+5/8=1 1/4 or 1.25
6+1 1/4=7 1/4 or 7.25
Answer:
(5a−3)^2
Step-by-step explanation:
25a^2 - 30a + 9
Factor the expression by grouping. First, the expression needs to be rewritten as 25a^2+pa+qa+9. To find p and q, set up a system to be solved.
p+q=−30
pq=25×9=225
Since pq is positive, p and q have the same sign. Since p+q is negative, p and q are both negative. List all such integer pairs that give product 225.
−1,−225
−3,−75
−5,−45
−9,−25
−15,−15
Calculate the sum for each pair.
−1−225=−226
−3−75=−78
−5−45=−50
−9−25=−34
−15−15=−30
The solution is the pair that gives sum −30.
p=−15
q=−15
Rewrite 25a^2 - 30a + 9 as (25a^2−15a)+(−15a+9).
(25a^2−15a)+(−15a+9)
Factor out 5a in the first and −3 in the second group.
5a(5a−3)−3(5a−3)
Factor out common term 5a−3 by using distributive property.
(5a−3)(5a−3)
Rewrite as a binomial square.
(5a−3)^2
N = 33 and m = 6 substitute in the values in place of the variables to get 33 - 5*(6). distribute the five to get 33 - 30 =3. the answer is three
Answer:
Option C.
Step-by-step explanation:
It is given that the ball's height, in feet, is modeled by the function
where, x represents time in seconds.
We need to find the height of the ball when Sarina throws it. It means, we need to find the initial height of the ball.
Substitute x=0 in the given function, to find the initial height.
The height of the ball is 3 feet when Sarina throws it.
Therefore, the correct option is C.
Answer:
Circumference of Circle A is about 16 units larger than the Circumference of Circle B
Step-by-step explanation:
Formula for Circumference of a circle = πd
Where, d = diameter of circle
Thus:
Circle A diameter = 13
Circle B diameter = 8
Therefore:
Circumference of Circle A = π*13 = 40.8407045 ≈ 41 unit (nearest whole number)
Circumference of Circle B = π*8 = 25.1327412 ≈ 25 unit (nearest whole number)
✔️Difference between circumference of Circle A and Circle B = 41 - 25 = 16
Therefore the Circumference of Circle A is about 16 units larger than the Circumference of Circle B
