Step-by-step explanation:

The amount of wrapping paper needed for the square pyramid gift box is: 96.72 in.².

Surface area of a square pyramid = area of the square base + area of the 4 triangular faces = s² + 4(1/2bh).

We are asked to find the amount of wrapping paper that would be needed to wrap the gift box, which is the surface area of the gift box that has a square pyramid shape.

Given the following dimensions of the gift box:

s = 5.2 in.

b = 5.2 in.

h = 6.7 in.

Plug in the values into s² + 4(1/2bh):

Surface area of a square pyramid = 5.2² + 4(1/2 × 5.2 × 6.7).

Surface area of a square pyramid = 96.72 in.²

Therefore, the amount of wrapping paper needed for the square pyramid gift box is: 96.72 in.².

Answer:

Chicago

Step-by-step explanation:

Compare the temperatures:

-4, -14, -11, -13

Numbers become smaller to the left on the number scale.
For instance, -10 is less than -5.

So, -13, -11, and -4 are all greater than -14.

And the lower the temperature, the colder it is.

Thus, Chicago is the coldest.

Answer:

1.75 + 0.3x = 7.45; 19 minutes

Step-by-step explanation:

The cost of the phone call is found by 1.75 + 0.30 multiplied by the number of minutes the calls lasts.  The cost of the call is 7.45 so 1.75 + 0.3x = 7.45.  Begin by subtracting 1.75 from each side of the equation.  That leaves 0.3x = 5.7.  Then divide both sides by 0.3.  This gives x = 19.

Answer:

(B)45°, 67.5°

Step-by-step explanation:

A regular polygon is a polygon in which all the sides are equal.

An Octagon is a polygon with 8 sides.

Since it is a Regular polygon, the following holds:

1.The Radii are equal

2. The angle Subtended by two radii are equal for all triangles in the octagon.

3. There are 8 Isosceles triangles in the octagon.

(a)Measures of angle formed by Two radii

From the centre of the octagon, there are 8 equal angles.

Sum of Angle at a point= 360°

Each Angle=360°÷ 8 = 45°

The measures of angle formed by two radii is 45°.

(b)a radius and a side of the polygon.

Since the triangles are Isosceles, the base angles at the side of the octagon are equal.

Let x be the angle made by a radius with a side.

From (a) above,

x+x+45°=180°(Sum of Angle in a Triangle)

2x=180-45°

2x=135°

x=135°÷2=67.5°

The angle between a radius and a side of the polygon is 67.5°.

Step-by-step explanation:

We can first find the GCD or GCF of 28 and 91. 91 in its simplest form is 13*7. 28 in its simplest form is 2*2*7. The only common factor they have is 7, so 7 is the GCD. We can divide both by 7 to get [tex]\frac{4}{13}[/tex]

Complete question is;

Write the equation of line in slope-intercept form. Line parallel to y = 0.5x + 3 that passes through the point (−9,12)

Answer:

y - 12 = 0.5(x + 9)

Step-by-step explanation:

We want to find the line parallel to y = 0.5x + 3 that passes through the point (−9,12).

To some this, we will use the equation;

y - y1 = m(x - x1)

Here, x1 = -9, y1 = 12, m = 0.5

Thus;

y - 12 = 0.5(x - (-9))

y - 12 = 0.5(x + 9)

Answer: 3.5 hours

Step-by-step explanation:

From the question, we are informed that Ray's burns 326 calories every hour. We are further told that he ate a doughnut that had 320 calories, and a latte had 820 calories. The total calories will be:

= 320 + 820

= 1140 calories

The number of hours needed to burn the calories will be the total calories divided by the amount of calories burnt in an hour. This will be:

= 1140/326

= 3.5 hours

I can't really give a step by step but just find the distance for the numerator and denominator and simplify

Answer:

6h+14k

Step-by-step explanation:

Multiply 2by 3h which gives 6h then multiply 7k by 2 which gives 14k.

Since 6h and 14k are not like terms u cannot add so your answer will be 6h + 14k.

Answer:

9h² + 42hk + 49k²

Step-by-step explanation:

Given

(3h + 7k)²

= (3h + 7k)(3h + 7k)

Each term in the second factor is multiplied by each term in the first factor, that is

3h(3h + 7k) + 7k(3h + 7k) ← distribute both parenthesis

= 9h² + 21hk + 21hk + 49k² ← collect like terms

= 9h² + 42hk + 49k²

3. 3x = 12

An open statement in math means that it utilizes variables, and can only be concluded as being "true" or "false". The problem would result in asking whether or not it is always true or not. In this case, x will be true when you plug in 4, however, it will not be true when you plug in any other number. Therefore, it is a closed statement that can be falsified.

4. Open.

The statement can be true if the variable g is 35, however, it is false if it is not. An open statement concludes that it may or may not be correct, thereby being open.

Answer:

64

Step-by-step explanation:

- 12 + 16 - 5 (-12)
- 12 + 16 + 60
4 + 60
= 64

Answer:

64

Step-by-step explanation:

If x = –12 and y = 16, evaluate x + y – 5x.

Solution,

= x + y - 5x

= -12 + 16 - 5 ( -12 )

= - 12 + 16 + 60

= - 12 + 76

= 64
