Here is a cuboid,
80 cm
30 cm
30 cm
Work out the total surface area of this cuboid.
(4)

Answers

Answer 1

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

Answers

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

What is the value of the expression
3+(2+8)^2+4*(1/2)^4

Answers

Answer:

Use photo math, it will explain it all

Use PEMDAS

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)

Write the equation of the line (y = mx+b) that has a slope of 2/3 and passing through the point (-6, 4)​

Answers

Answer:

y = 2/3x + 4

Step-by-step explanation:

y = 2/3x + b

substitute

4 = 2/3(-6) + b

4 = -4 + b

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?

Answers

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.

Find the next 3 terms in this pattern: 18, -6, 2, ___, ___, ___.

Answers

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

Answers

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
