Answer:
60 feet
Step-by-step explanation:
Perimeter is the sum of the four sides of a rectangle
the formula for the perimeter of a rectangle = 2 x (length + breadth)
2 x (10 + 20)
2 x (30)
= 60 feet
Alternatively, you can add the sides together : 10 + 10 + 20 + 20 = 60 feet

Answer:
105
Step-by-step explanation:
To find the surface area, we need to find the area of all the sides. There are five sides, but four of them are exactly the same.
To find the area of a triangle, you need to do width x height / 2. The width is five and the height is eight. 5 x 8 / 2 = 20. There are three more sides that have the exact same area as this. Since there are four sides that have a surface area of twenty, we do 20 x 4 = 80. Then, we find the area of the bottom piece. To find the area of a square, you need to do length x width. 5 x 5 = 25. Then, we add our two areas to get the final result. 80 + 25 = 105. Therefore, 105 is the surface area of the pyramid.
Hope this helps! Thanks for brainliest! :D

Jodie has chosen a set of vases for her wedding registry. The vases are cylindrical and their dimensions (in inches) are as follows.
• Vase A: h = 12 and r= 2
• Vase B: h = 6 and r = 4
Which of the following statements about the volumes of the vases is true?
OA. The volume of vase A is half the volume of vase B.
ОВ.The volumes of the two vases are equal.
OC. The volume of vase B is half the volume of vase A.
OD.The volume of vase B is four times the volume of vase A.
Answer:
Option A
Step-by-step explanation:
V = πr2h = π·22·12 ≈ 150.79645 - Vase A
V = πr2h = π·42·6 ≈ 301.59289 - Vase B

Given in the figure below, find the values of X and Z.
Step-by-step explanation:
8x-12+104=180°
= 8x=180-92
= x=88/8
= x=11°
104=y
Answer:
Step-by-step explanation:
Angles (8x - 12) and 104 are "straight angles;" their sum is 180 degrees.
Therefore, 8x - 12 + 104 = 180, or 8x - 12 = 76, or 8x = 88.
Dividing both sides by 8, we get x = 11
Angles z and 104 are vertical angles and are thus equal to one another. Thus, z = 104 degrees

Answer:
t (is less than or equal to) 96
Step-by-step explanation:
to solve for t, you need it to be isolated. to move the 3 to the other side, you need to multiply it on both. 3 x t/3= t and 32 x 3= 96, therefore t (is less than or equal to) 96.
i hope this helps :)
Answer:
t ≤ 96
Step-by-step explanation:
t / 3 ≤ 32
(multiply both sides by 3)
t / 3 * 3 ≤ 32 * 3
t ≤ 96
let f(x)=3x-2 and g(x)=x^2+4 find f(g(12)
Let f(x)=3x-2 and Let g(x)=x^2+4.
Find f(g(12)).
Answer:
442
Step-by-step explanation:
Find g(12) first.
12^2 + 4 = 144 + 4 = 148.
Now find f(148).
(3 x 148) -2 = 444-2 = 442.

If the probability of a cup drink being rasberry flavour is 0.29, what is the probability of a cup drink being cola flavour?
Answer: 0.71
Step-by-step explanation:
Since we have just two flavors, the probability of a cup drink being cola flavour will be calculated below:
P(R) + P(C) = 1
0.29 + P(C) = 1
P(C) = 1 - 0.29
P(C) = 0.71
Therefore, the probability of a cup drink being cola flavour is 0.71.
