The surface area of this square pyramid is,

⇒ SA = 296 cm²

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

To find the surface area of this square pyramid

Now, We know that;

the surface area of this square pyramid is,

⇒ SA = B + 1/2 pl

Where, B represents the area of the base. p represents the perimeter of the base. l represents the slant height.

Now, We get;

B = 12 x 8

B = 96

p = 2 (12 + 8)

p = 40

l = 10

Thus, the surface area of this square pyramid is,

⇒ SA = B + 1/2 pl

⇒ SA = 96 + 1/2 x 40 x 10

⇒ SA = 96 + 200

⇒ SA = 296 cm²

Step-by-step explanation:

Translating the triangle DEF involves moving the triangle along the coordinate plane

The y-coordinate of point D after the translation (x, y) → (x + 6, y – 4) is 1

From the figure the coordinate of D is:

D = (-2.5,5)

The rule of translation is given as:

(x, y) → (x + 6, y – 4)

So, we have:

(x, y) → (-2.5 + 6, 5 – 4)

Evaluate the sum and the difference

(x, y) → (3.5, 1)

Remove the x-coordinate

y → 1

Hence, the y-coordinate of point D after the translation is 1

Answer:

56ft

Step-by-step explanation:

first you need to break the shape u so 1 rectangle and 2 triangles so first we need to find the area of the rectangle

Area of rectangle= w x h so 5* 8= 40

Area of triangle = .5 x b x h so 4 x 4 x .5 = 8 and since we have 2 double that and you get 16 so then you need to add it all up and u get the answer 56

A circle with two chords is given with length X, 8, x-12, 12. Thus, The value of x is 24.

If the considered circle has center O and chord AB, then if there is perpendicular from O to AB at point C, then that point C is bisecting(dividing in two equal parts) the line segment AB.

Or

|AC| = |CB|

Using the theorem of intersecting chords

[tex]12x =8(x-12)\\\\12x = 8x - 96\\\\12x - 8x = 96\\\\4x = 96\\\\x = 24[/tex]

The value of x is 24.

Answer:

x = -9/2

Step-by-step explanation:

1. Divide 9 by -1/3:

[tex]\frac{9}{1}[/tex] ÷ [tex]-\frac{1}{3}[/tex] = [tex]\frac{9}{1}[/tex] · [tex]-\frac{3}{1}[/tex]

= -27

2. Divide both sides by 2:

2(x - 9) = -27

[tex]\frac{2(x-9)}{2} = \frac{-27}{2}[/tex]

(x - 9) = [tex]-\frac{27}{2}[/tex]

3. Add 9 to both sides:

x = [tex]-\frac{9}{2}[/tex]

(or 4.5 if you need it in decimal form)

the.answer is a a pair of shoes is on sale for 25% off the regular 30 at the store

P = 0.75m represents the proportional relationship, therefore, the profit earned for each muffin sold is: $0.75.

If two variables, i.e. P and m are directly proportional to each other, the relationship between them can be represented as P = km, where k is the constant.

Given that P = 0.75m represents the proportional relationship between the profit earned and muffins sold, the constant, k, is 0.75, which is the profit earned for each muffin sold.

Given the fraction of each colored chalk, Andrea is right that less than 1/2 the chalk in the bucket is blue.

Total = 2/6 + 5/12 + 3/12

= (4+5+3) / 12

= 12/12

= 1

Fraction of blue : Total chalk

= 5/12 : 1

Blue = 5/12 ÷ 1

= 5/12 × 1/1

= 5/12

= 0.42

So,

1/2 = 0.5
