What is the total surface area?? PLEASE HELP THIS IS A QUIZ IM SO CONFUSED
Answer:
246 cm
Step-by-step explanation:
So I solved for the two triangles, 6x8=48/2=24, since there are 2, I multiplied by 2 to get 48 (Could've kept it just as 48 but it's good to keep the habit of dividing by 2 to get area of a triangle). Then I did 6x9 for the front rectangle to get 54, and then solved for the right and back rectangle by doing 9x8 to get 72, 72x2=144
144+48+54= 246

Answer:
a. 5,040 ways
b. 210 ways
Step-by-step explanation:
a) We want to pick 4 numbers out of 10 given that orders matter
If orders do matter, it will be a permutation problem
Mathematically;
n P r = n!/(n-r)!
In this case, n is 10 and r is 4
Thus, we have it that;
10 P 4 = 10!/(10-4)! = 5,040
b) if orders do not matter
It will be a combination problem
n C r = n!/(n-r)!r!
n = 10 and r = 4
10 C 4 = 10! /(10-4)!4!
= 210
A teacher is making a seating chart in order to group his class of 30 students. He puts 5 students in each group.
What should the teacher do to figure out how many groups he will have?
Answer:
The teacher should divide the amount of students by 5, that way they'll find how many groups they'll have. And the amount of groups they'll have is 6 groups of 5 students, you didn't ask for this part but I decided it'd be best to add it. Hope this helps, have an amazing day you awesome human! ^w^

for f(x) = 5x - 7 and f(x) = -3, what is the value of x
Answer:
Step-by-step explanation:
hello :
f(x) = 5x - 7 and f(x) = -3
5x - 7 = -3
5x=7-3
5x=4
x=4/5
Answer:
x = 4/5
Step-by-step explanation:
5x - 7 = -3
5x = -3 + 7
5x = 4
x = 4/5
Check:
5*4/5 - 7 = -3
4 - 7 = -3
First, consider the number of moves as a
sequence: 1, 3, 7, 15, 31, 63,
.
To find a pattern, look at the differences between
consecutive terms. These differences also form a
sequence.
3-1 = 2,7 – 3 = 4, ...
Complete the sequence:
2, 4, ___, ___, ____
Answer:
The sequence is 2, 4, 8, 16, 32
The next answer is 2
Step-by-step explanation:
The missing terms of the required sequence are 8, 16 and 32 respectively.
What is a geometric sequence?In a geometric sequence, the ratio of two consecutive terms are always equal.
The general expression for the nth term is given as aₙ = a₁ × rⁿ⁻¹ .
The sum of n terms for this sequence is given as Sₙ = (rⁿ - 1)/(r - 1)
The given sequence is 1, 3, 7, 15, 31, 63...
Then, the sequence formed by subtracting the consecutive terms are given as,
3 - 1, 7 - 3, 15 - 7, 31 - 15, 63 - 31 .....
Which can be rewritten as,
2, 4, 8, 16, 32......
It is a geometric sequence as ratio of the consecutive terms are equal,
4/2 = 8/4 = 16/8
Hence, the required sequence is a geometric sequence found as 2, 4, 8, 16, 32......

Answer:
x = 4
Step-by-step explanation:
In similar triangles, the ratios of the length of the corresponding sides are equal.
[tex]\frac{CD}{ED}=\frac{GD}{FD}\\\\[/tex]
[tex]\frac{48}{5x-2}=\frac{40}{2x+7}\\[/tex]
Cross multiply,
48*(2x + 7) = 40*(5x - 2) {use distributive property: a*(b+c)=(a*b)+ (a*c)}
48*2x + 48*7 = 40*5x - 40*2
96x + 336 = 200x - 80 {Subtract 96x from both sides}
336 = 200x - 96x - 80
336 = 104x - 80 {Add 80 to both sides}
336 + 80 = 104x
416 = 104x {divide both sides by 104}
416/104 = x
x = 4
