Answer:
Number of pineapples = 10
Number of pears = 10 + 9 = 19
Number of kiwis = 10 - 2 = 8
Step-by-step explanation:
Money = $ 13.5
Cost of a pear = $ 0.5
Cost of a pineapple = $ 1.5
Cost of a kiwi = $ 0.3
let the number of pineapple = p
Number of pears = p + 9
Number of kiwis = p - 2
Cost is
0.5 (p + 9) + 0.15 p + 0.3 (p - 2) = 13.5
0.5 p + 4.5 + 0.15 p + 0.3 p - 0.6 = 13.5
0.95 p = 9.6
p = 10
So, number of pineapples = 10
Number of pears = 10 + 9 = 19
Number of kiwis = 10 - 2 = 8
Hello there!
4x² = 100
We wanna start by dividing both sides by 4
4x²/4 = 100/4
x² = 25
Now we can take square root
x = +/-√25
x = 5 or x = -5
As always, it is my pleasure to help students like you!
Answer:
Step-by-step explanation:
If the sum of two angles = 180°
Then the pair of angles will be supplementary.
If the sum of two angles = 90°
Then the pair of angles will be complementary.
Sum of angles having measures 98° and 82° = 98° + 82°
= 180°
Therefore, both the angles will be supplementary.
Sum of angles having measures 134° and 36° = 134° + 36°
= 170°
Therefore, these angles are neither supplementary nor complementary.
So the answer is NEITHER.
2 radians = 2 full rotations
pi = 3.14
circumference of wheel = 2(pi)r
= 20 * 3.14
=62.8 cm
= 0.628m
meters rolled = 0.628 * 2
=1.256 m
Second moment of area about an axis along any diameter in the plane of the cross section (i.e. x-x, y-y) is each equal to (1/4)pi r^4.
The second moment of area about the zz-axis (along the axis of the cylinder) is the sum of the two, namely (1/2)pi r^4.
The derivation is by integration of the following:
int int y^2 dA
over the area of the cross section, and can be found in any book on mechanics of materials.
