3. If the lateral surface area of a
cylinder is 94.2 cm2 and its height
is 5 cm, then find
i) radius of its base
ii) its
volume
Use pi = 3.14
Step-by-step explanation:
Answer:
I) R = 3 cm;
II) V = 14.3 cm³.
Step-by-step explanation:
I) C = 94.2 ÷ 5 = 18.84
A cylinder has a base with a circumference of 18.84cm.
[tex]R=\dfrac{C}{2\pi } =\dfrac{18.84}{2 \cdot 3.14} =\dfrac{18.84}{6.28} =3 \: (cm)[/tex]
II) [tex]V=\pi R^{2}H=3.14 \cdot 3^{2} \cdot 5 = 141.3 \: (cm^{3})[/tex]
On the coordinate plane shown, what is the distance from point Y to point Z? Round your answer to the nearest hundredth.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, but I would solve a similar question:
Find the distance between the two points shown on the coordinate plane. (Round your answer to the
nearest tenth.)
Solution:
The coordinate plane is a plane formed by the intersection of the vertical line and the horizontal line. The vertical line is known as the y axis and the horizontal line is the x axis. The y axis and x axis intersect at a point known as the origin.
The distance between two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] on the coordinate plane is given by:
[tex]Distance=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Given points (-2, -1) and (2, 3), the distance is:
[tex]Distance=\sqrt{(3-(-1))^2+(2-(-2))^2}=\sqrt{4^2+4^2}=\sqrt{16+16}=\sqrt{32}[/tex]

Find the measure of Angle A. (include and explanation so I could do the rest on my own, preferably :)
Answer:
13) Angle A is 30°
14) Angle A is 45°
15) Angle A is 40°
16) Angle A is 40.5°
Step-by-step explanation:
By the angle sum theorem for the interior angles of a triangle, we have;
13) 130° + 2·x + 3·x = 180°
∴ 2·x + 3·x = 180° - 130° = 50°
2·x + 3·x = 5·x = 50°
x = 50°/5 = 10°
∠A = 3·x = 3 × 10° = 30°
∠A = 30°
14) 3·x + 9 + 4·x + 9 + 78° = 180°
7·x + 18 + 78° = 180°
7·x = 180° - (18 + 78)° = 180° - 96° = 84°
x = 84°/7 = 12°
∠A = 3·x + 9 = 3 × 12° + 9 = 45°
∠A = 45°
15) 90° + x + 51 + x + 61 = 180°
∴ x + 51 + x + 61 = 180° - 90° = 90°
2·x + 112 = 90°
2·x = (90 - 112)° = -22°
x = -22°/2 = -11°
x = -11°
∠A = x + 51 = -11° + 51 = 40°
∠A = 40°
16) x + 79 + x + 49 + 70° = 180°
x + x = (180 - 70 - 79 - 48)° = -17°
2·x = -17°
x = -17°/2 = -8.5°
x = -8.5°
∠A = x + 49 = (-8.5 + 49)° = 40.5°
∠A = 40.5°.

Does anyone know ?
The sum of the interior angles of this irregular hexagon is 720
How to determine the sum of the angles?The sum of the interior angles of a polygon is:
Sum = 180 *(n - 2)
A hexagon has 6 sides.
So, we have:
Sum = 180 *(4 - 2)

Three Duos is worth the same amount as two Trios. Steve has thirty-six Trios. If he converts all of his Trios to Duos, then how many Duos will Steve have?
Answer:
Steve has 54 Duos
Step-by-step explanation:
Proportions
It's given three duos (D) is worth as two trios (T), i.e.:
3D = 2T
Steve has 36 trios, that is, 36T. To find the equivalence to duos, we multiply the given relationship by 18:
18*3D = 18*2T
Operating:
54D = 36T
Therefore, 36 trios are equivalent to 54 duos.
Steve has 54 Duos

Find the 26th term of an arithmetic sequence with ai = -33 and d= 4.
O 67
O-130
O 71
O-129
Answer:
The 26th term of an arithmetic sequence is:
[tex]a_{26}=67[/tex]
Hence, option A is true.
Step-by-step explanation:
Given
a₁ = -33d = 4An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting a₁ = -33 and d = 4 in the nth term of the sequence
[tex]a_n=-33+\left(n-1\right)4[/tex]
[tex]\:a_n=-33+4n-4[/tex]
[tex]a_n=4n-37[/tex]
Thus, the nth term of the sequence is:
[tex]a_n=4n-37[/tex]
now substituting n = 26 in the nth term to determine the 26th term of the sequence
[tex]a_n=4n-37[/tex]
[tex]a_{26}=4\left(26\right)-37[/tex]
[tex]a_{26}=104-37[/tex]
[tex]a_{26}=67[/tex]
Therefore, the 26th term of an arithmetic sequence is:
[tex]a_{26}=67[/tex]
Hence, option A is true.

if a triangle has a area of 42 cm^2 and a base of 8 cm, what is the height?
show work plsssss
Answer:
The height would be 10.5 cm
Answer:
hb=10.5cm
Step-by-step explanation:
Area of triangle = 1/2(height x base)
The problem states that base is 8 cm greater than the height; therefore, base-8 = height.
A = 1/2(b*h)
42 = 1/2(b*[b-8])
84=(b^2-8b)
rearrange to
b^2 - 8b -84
factor to
(b+8)(b-14)
Therefore, b = -8 cm which makes no sense and
b = +14 cm
and height = 14-8 = 6
Check:
1/2(b*h) = area
1/2(14*6) = 1/2(84)=42

Answer:
the probability would be 8/15
The solution is Option 2.
The probability of selecting a ball that has an odd number and is divisible by 5 is 2/15
What is Probability?
The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
The value of probability lies between 0 and 1
Given data ,
Let the probability of selecting a ball that has an odd number and is divisible by 5 be P
Now , the equation will be
The total number of balls in the bag = 15 balls
The numbered balls in the bag A = { 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 }
The numbers of the balls in the bag that are divisible by 5 B = { 5 , 10 , 15 }
The odd numbers from the set B = { 5 , 15 }
So , the probability of selecting a ball that has an odd number and is divisible by 5 P = odd numbers from the set B / total number of balls in the bag
Substituting the values in the equation , we get
The probability of selecting a ball that has an odd number and is divisible by 5 P = 2/15
Therefore , the value of P is 2/15
Hence , the probability is 2/15
