Length = 80
Breadth = 30
Height = 30
Total surface area of a cuboid is=
2 ( lb + bh + hl )
Putting the values in the formula,
We get,
= 2 [ (80 x 30) + (30 x 30) + (30 x 80)]
= 2 (2400 + 900 + 2400)
= 8100 cm²

What is the value of the expression
3+(2+8)^2+4*(1/2)^4
Answer:
Use photo math, it will explain it all
First here's the expression written out a little clearer
[tex]3+(2+8)^2+4*(\frac{1}{2} )^4[/tex]
Parentheses: (2+8) = (10).
Exponents: 10^2 is 100, and [tex](\frac{1}{2} )^4[/tex] is [tex]\frac{1}{2} \cdot \frac{1}{2} \cdot \frac{1}{2} \cdot\frac{1}{2} =[/tex] [tex]\frac{1}{16}[/tex]
Multiplication and division: 4 * 1/16 is [tex]\frac{4}{16}[/tex] or [tex]\frac{1}{4}[/tex] simplified
Addition and subtraction: Go left to right. 3 + 100 + [tex]\frac{1}{4}[/tex] = 103.25 (final answer)
If you place a 37-foot ladder against the top of a 12-foot building, how many feet will the bottom of the ladder be from the bottom of the building?
The building will be making 90° with the ground/horizontal.
Then we can apply Pythagoras theorem.
(Base)² + (Height)² = (Hypotenuse)²
=> x² + (12 foot)² = (37 foot)²
=> x² = (37 foot)² - (12 foot)²
We can expand LHS using a² - b² = (a + b)(a - b)
=> x² = (37 + 12 foot)(37 - 12 foot)
=> x² = 49 * 25 foot²
=> x² = (7 * 5)² foot²
=> x = 7 * 5 foot
=> x = 35 foot.
The teacher wants to group 87 students into teams which have the same number of students. There must be more than one team. At least how many teams are there and how many students are there in each team?
Answer:
3 teams and 29students in each team.
let, the team be x,y,&z
given all the team r equal so, x=y=z
x+y+z=87
3x=87
x=87/3
x=29
we get, x=y=z=29
hope it helps.

Find the next 3 terms in this pattern: 18, -6, 2, ___, ___, ___.
Answer: -0.67, 0.22, -0.074
Step-by-step explanation:
This is a geometric sequence because it has a common ratio. The common ratio is divide by -3.
18 / -6 = -3
-6 / 2 = -3
Therefore, we'd continue that ratio.
2 / -3 = -0.67
-0.67 / -3 = 0.22
0.22 / -3 = -0.074
It may ask you to write that in fraction form^^
In that case, 2/-3, then 2/-3 / -3, etc etc. :)
Divide by -3

The tables below show the values of Y for different values of X
Answer:
Option D
Step-by-step explanation:
Rate of change of a linear function between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Rate of change 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the given table,
Rate of change of the function between (-2, 6) and (-4, 9),
Rate of change 'm' = [tex]\frac{9-6}{-4-(-2)}[/tex]
m = [tex]\frac{3}{-2}[/tex]
Initial value = y-intercept
Let the equation of the line passing through a point (h, k) is,
y - k = m(x - h)
If a point (-2, 6) is lying on the graph of the function,
y - 6 = [tex]-\frac{3}{2}(x+2)[/tex]
y = [tex]-\frac{3}{2}x-3+6[/tex]
y = [tex]-\frac{3}{2}x+3[/tex]
Y-intercept of the function = 3
Therefore, initial value of the function = 3
Option D is the answer.

Solve for x. 5a/x = 5b/ x-1
Answer:solve for x 5a/x = 5b/ x-1 - 11261842. ... out the denominators by multiplying both sides by the bottom, you can then factor to find X= a / (a-b).

Answer:
TU = 28.5
Step-by-step explanation:
The triangles are congruent because of side-angle-side
TU = VU because corresponding sides of congruent triangles are congruent.
so:
3x + 9 = 7x - 17
simplify:
4x = 26
x = 6.5
TU = 3(6.5 + 9) = 19.5 + 9 = 28.5
Answer:
3x+9=7x-17
26 = 4x
x=6.5
TU:28.5

Answer:
y = 2/3x + 4
Step-by-step explanation:
y = 2/3x + b
substitute
4 = 2/3(-6) + b
4 = -4 + b
