Answer:
It is [tex]\frac{1}{2}[/tex] (12 × 4) = 24
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] (base × height) = area of triangle
[tex]\frac{1}{2}[/tex] (12 × 4) = area
area = 24

"Find the surface area of each pyramid. Round to the nearest tenth if necessary."
Answer: The total surface area is 633.9
Step-by-step explanation:
12.25 times 15.75, then divide by 2 = 96.46875 (this is the area of the triangle
Then times 4 = 385.875 (Because there are four triangles
15.75 times 15.75 = 248.0625 (The area of the square)
The sum is 633.9375
Rounded = 633.9

How to solve this? WILL GIVE BRAINLIEST
HELP MEEEE!!!!!!!!!!!!!!!!!
How do you find the surface area of this?
Answer:
132
Step-by-step explanation:
No way you can find the whole area with one solution. So we have to go by each shape.
Let's start with the triangle on top, only one part of it. We know that half of the base is 3. We could go long and hard and use the pythagorean theorem and then repeat that 8 times. Instead, you can imagine moving the 2 triangles into a rectangle. Now you have a rectangle that is 3x4 inches. Repeat 4 times for each of the triangles. Then just the square which is 6x6. Add them and bam!

one step equation Y/1.8=80 what’s the answer?? ( with steps )
Answer:
5) Y = 144
Step-by-step explanation:
[tex]\frac{Y}{1.8} = 80[/tex]
Bring 1.8 from the numerator to the denominator and change the sign from divide to multiply. Also, the 1.8 switches sides so the equation looks like:
Y = 80*1.8
Y = 144
Hence, Y is equal to 144.

The circumference of a circle is 125.6 millimeters. What is the circle's diameter?
Use 3.14 for .
Answer:
C = 2 pi r, so diameter is 40!
Step-by-step explanation
125.6 = 2 pi r
125.6 divided by 2 is 62.8.
Now its, 62.8 = pi times r
62.8/3.14 = 20.
r = 20
but this is the radius so the diameter is 2 times for than the radius. 20 x 2 = 40

B. 4
C. 1, 2, 5, 7, 8, 10
D. 1, 3, 4, 5, 6, 7, 8, 10
Answer:
1 3 4 5 6 7 8 10
Step-by-step explanation:
the numbers 7,8,9,0 represent 8th graders and the groups 1 3 4 5 6 7 8 10 all contain at least one of the numbers while the others groups dont meaning they are no 8th graders in groups 2 or 9

It is equal. The same either way. :)
Hey there!
PROBLEM #1. 4 * 2,160
4 * 2,160
= 2,160 * 4
= 2,160 + 2,160 + 2,160 + 2,160
= 4,320 + 4,320
= 8,640
Therefore, the answer should be: 8,640
Problem #2. 4 * 2,610
4 * 2,610
= 2,610 * 4
= 2,610 + 2,610 + 2,610 + 2,610
= 5,220 + 5,220
= 10,440
Therefore, the answer should be:
10,440
Good luck on your assignment & enjoy your day!

X/3+1 = 6
Answer: x=15
Step-by-step explanation:
x/3+1= 6
Step 1: Subtract 1 from both sides (always do inverse operations with the number, not the x term(s))
x/3 + 1-1 = 6-1
x/3= 5
Step 2: Now we need to isolate x (get it on its own). To do this, we must move the 3 to the other side, which we will do by multiplying the 3 and the 5 (as since the 3 was used for divisision, its inverse operation is multiplication).
x/3 = 5
x = 5x3
x= 15
Step 3: Check by using PITA, or "Plugging In the Answers"
We came to the conclusion that x=15. Now, we can "plug in", or substitute the x in the equation for 15:
x/3 + 1= 6
15/3 + 1= 6
5+ 1= 6
6=6
Correct ✔️
Answer:
X = 24
Step-by-step explanation:
3 + 1 = 4
X/4 = 6
Multiply both sides by 4
X = 24

A prism has a length of 4 centimeters, width of 2 centimeters, and height of 10 centimeters. Use the prism to complete the statements. The surface area of the prism is cm2. The volume of the prism is cm3.
Answer:
Surface area = 136 cm² Volume = 80cm³
Step-by-step explanation:
Surface Area = face 1 + face 2 + face 3 + face 4+ face 5 + face 6
SA = 2(4) + 2(4) + 2(10) + 2(10) + 4(10) + 4(10)
SA = 8 + 8 + 20 + 20 + 40 + 40
SA = 16 + 40 + 80
SA = 136

Volume = l*w*h
Volume = 4*2*10

The table shows the cost of hiring a plumber for the first 3 hours of a job.
Which graph shows the points in this table?
Ps: sorry there are too many screen shots.
Answer: it's A
Step-by-step explanation:
since the cost for hiring a plumber for three hours costs $120 so in graph A the graph has more likely stopped at $120 on the y axis which can be said as the cost axis too. I'm pretty sure the answer is A!

solve the inequality
1/5x+3>9
Answer:
Step-by-step explanation:
First, you would want to subtract the 3 on the left side to the right side to get the 1/5x to be alone.
1/5x>6
Next, we need to solve for x, by multiplying 5 to cancel out the 1/5.
(5)1/5x>6(5)
That leaves us with x>30
treat the inequality sign as an equal sign, that should help
