help me pls I'll give brainliest to the person who has the correct question-Determine the surface area of the pyramid
Answers
Answer:
surface area: 16 mm
Step-by-step explanation:
surface area is only length (8mm) times width (8mm), so in this case you would disregard the height (10mm) and just multiply 8 x 8

Which equation has (100, –100) as a solution?
A. y = 0.1x – 99
B. y = – x – 100answer
C. y = x
D. y = –x
Answers
Answer:
D
Step-by-step explanation:
Ok so you just need to plug in the points
A. -100= 0.1(100)-99 (FALSE)
B. -100= -100-100 (FALSE)
C. -100= 100 (FALSE)
D. -100= -(100) (TRUE)
Why did I plug in the numbers? Because its (x,y) meaning 100=X and -100=Y. So just plug them in to know the correct answer.

Step-by-step explanation:
for some reason the equation at the top says 7(x+2) but both of the equations at the bottom say 7(x-2)... I'm just going to do 7(x-2)
Emmanuels Work:
7(x-2)=91
distribute the 7 by multiplying both x and -2 by it
7x-14=91
add 14 to both sides
7x=105
divide both sides by 7
x=15
Mauricio's Work:
7(x-2)=91
to get rid of the 7 multiplication, divide both sides by 7
x-2=13
add 2 to both sides
x=15
I only know the first one with the method Emmanuel is doing sorry ;(

Have an amazing day!
PLEASE RATE!
Answer:
Step-by-step explanation:
Alright, so the answer is $400. So we know that $284 is a discount on the whole price, 29% off. So 284 is 71% of the whole price, 100%-29%=71%. So then I just divided 284 by 71 and got 4. 284/71=4. Because I divided it by 71, $4 is 1% of the whole price, so I multiplied 4 by 100 and got $400 as the original price. You can just do this equation with any type of calculator, also please select my answer as the brainliest.✌

16.2 is what percent of 90?
18%
14.6%
90%
16%
Answers
Answer:
18%
Step-by-step explanation:
Step 1: We make the assumption that 90 is 100% since it is our output value.
Step 2: We next represent the value we seek with x
Step 3: From step 1, it follows that 100%=90
Step 4: In the same vein, x%=16.2
Step 5: This gives us a pair of simple equations:
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
Step 7: Taking the inverse (or reciprocal) of both sides yields
Therefore, 16.2 is 18% of 90
Answer:
16%
Step-by-step explanation: If its 16.2 out of 90 its %16 bc the .2 is not more than 5
The length of two sides of triangle are 4cm and 5cm. Between what two
measures should the length of the third side fall?
Answers
Answer:
1 and 9
Step-by-step explanation:
By the Triangle Inequality Theorem, the sum of two side lengths of a triangle is always greater than the length of the third side.
In other words, in a triangle with side lengths [tex]a, b,[/tex] and [tex]c,[/tex] we always have [tex]a+b > c.[/tex]
Applying this to this question, the other side length, [tex]x,[/tex] must satisfy the following inequalities:
[tex]4+5 > x,\\x+5 > 4,\\x+4 > 5.[/tex]
Solving these inequalities gives
[tex]x < 9,\\x > -1,\\x > 1.[/tex]
Combining these solutions, we have [tex]1 < x < 9.[/tex] Therefore, the length of the third side falls between 1 and 9.
