Answer:
B. Scalene and D. Acute
Step-by-step explanation:
Check each answer.
A. Equilateral
All sides or all angles are not equal. So it is not equilateral.
B. Scalene
All sides are unequal. So it is scalene.
C. Obtuse
No any angle is greater than 90°. So it is not obtuse.
D. Acute.
All angles are less than 90°. So it is acute.
E. Isosceles
No two sides are equal. So it is not isosceles.
F. Right
No angle is 90°. So it is not right
Therefore, only answers B. Scalene and D. Acute are correct.
2 numbers are 0.45 and 0.4. 0.4 would equal 2/5 in simplest form. 0.45 in simplest form is 9/20. hope this helps.
Answer:
x = -6
Step-by-step explanation:
3(x+4)-1=-7
Add 1 to each side
3(x+4)-1+1=-7+1
3(x+4)=-6
Divide by 3
3/3(x+4)=-6/3
x+4 = -2
Subtract 4 from each side
x+4-4 = -2-4
x = -6
Answer:2.6
Step-by-step explanation:
Use your graphing calculator of you have one and if you don't you can find one online and plug in the equation and find the intersection . If you get 2.5571 round it to the nearest tenth and you should get 2.6
Area of the circle can be calculated using the following rule:
area = pi*(radius)^2
For the first circle:
We are given that:
area = 1040.9 square units ....> I
For the second circle:
We are given that:
radius = 27 units
Therefore:
area = pi * (27)^2 = 2290.221044 square units ....> II
For the third circle:
We are given that:
circumference = 87.92 units
Therefore:
circumference = 2*pi*radius = 87.92
radius = 13.99 units
area = pi*(13.99)^2 = 615.12799 square units ...> III
For the fourth circle:
We are given that:
diameter = 19 units
Therefore:
radius = 19/2 = 9.5 units
area = pi*(9.5)^2 = 283.528 square units ....> IV
Based on the above, the order according to increasing area would be:
IV , III , I , II
hope this helps :)
