Answer:

The surface area of the square pyramid is 280 units².

Step-by-step explanation:

As we know that the total surface area of a square pyramid can be obtained by identifying the length 'b' of its base and its slant height 's' by using the formula:

[tex]A=2bs+b^2[/tex]

From the figure, it is clear that

substituting the values in the formula

[tex]A=2bs+b^2[/tex]

[tex]A=2[/tex] [tex](10)[/tex] [tex](9)+(10)^2[/tex]

   [tex]=2[/tex] [tex](10)[/tex] [tex](9)+100[/tex]

   [tex]=280[/tex]

Therefore, the surface area of the square pyramid is 280 units².

Answer:

Yes, she is correct. Volume of the cylinder is V = πr²h. Therefore we need height and radius to calculate the volume. Height is given and the radius can be calculated from the circumference.

Step-by-step explanation:

Volume of cylinder
[tex]V = \text{area of circle} \times \text{height}\\V = \pi r^2 \times h[/tex]

For the volume of the cylinder we need the radius of the circle and height of the cylinder. The height is already known.

We can find the radius from the circumference.

Cirumference of the circle
[tex]C = 2 \pi r[/tex]

We can get the radius from rearranging the equation.

[tex]r = \frac{C}{2 \pi}[/tex]

Since C (circumference) is known we can easily calculate the radius.

With that we have all the needed information (height and radius) to calculate the volume of the cylinder.

Step-by-step explanation:

1. The average grade of Brenda :

2. During the second quarter, Brenda scored her lowest grade, which was an 82.

The total number of workers that earn $75 per day is 48

The average salary is calculated based on reported salaries of respondents. The average salary definition is to add the salaries in the sample together, then divide by the number of respondents.

Given that:

In a group of 60 workers, the average salary is $80 a day per worker.

If some of the workers earn $75 a day and all the rest earn $100 a day.

Let 'x' be the total number of workers that earn $75 per day.

So, the total number of workers that earn $100 per day is (60 - x).

As the average salary of 60 workers is $80.

Then,

[tex]\frac{75x + 100(60-x)}{60} =80[/tex]

or, 75 x + 6000- 100x = 80*68

or, -25x= -1200

       x= 48

So, the total number of workers earn $75 per day is 48.

Answer:

Step-by-this may be done by rearranging the equation. First, we start with the given equation:

0.05*10 = 0.5

In order to form a division equation, we may divide both sides by one of the terms being multiplied on the left-hand side. Let us divide by 10. By doing so, we get:

0.05 * 10 / 10 = 0.5/10

0.05  = 0.5/10ep

The measure of angle IJG in the inscribed quadrilateral is calculated as: 110°.

The opposite angles in a inscribed quadrilateral in a circle are said to be equal to 180 degrees, that is, they are supplementary.

angle IJG and angle GHI are opposite angles, therefore:

Angle IJG = 180 - angle GHI

Angle IJG = 180 - 70

Angle IJG = 110°

For closet

For rolls:-

Cylindrical body

Volume:-

Total rolls:-

Answer:

1372

Step-by-step explanation:

Rectangular closet dimensions:

Modelling the roll of toilet paper as a cylinder with dimensions:

If we sit the rolls of toilet paper in the closet with their circular ends as their bases, then we can calculate the number of rolls that cover the base of the closet by dividing the length (and width) of the closet by the diameter of the toilet roll.

⇒ 36 in ÷ 5 in = 7.2 in

Therefore, we can fit 7 toilet rolls along the length and 7 toilet rolls along the width of the closet, meaning that we can fit 7 × 7 = 49 toilet rolls over the base of the closet.

Now calculate how many toilet rolls we can stack on top of each other.

To do this, divide the height of the closet by the height of the toilet roll:

⇒ 108 in ÷ 3.75 in = 28.8

Therefore, we can stack 28 layers of 49 toilet rolls in the closet.

So the total number of toilet rolls = 28 × 49 = 1372

There are other ways of stacking the toilet rolls in the closet (for example, turning them on their side), however, we cannot calculate the number of rolls the closet fits by simply dividing the volume of the closet space by the volume of a toilet roll, since the toilet rolls are cylinders and so there will always be some space between them.

Answer:

13/36.

Step-by-step explanation:

First convert to improper fractions:

10 1/9 = (10*9 + 1)/9 = 91/9.

9 3/4 = (9*4 + 3)/4 = 39/4.

Next find the Lowest Common Denominator of 9 and 4.

This is 9*4 = 36.

Now convert both fractions to 36th:

For 91/9 we multiply by 4/4 and for 39/9 we multiply by 9/9

91*4 / 9*4 =  364/36 and 39*9 / 9*4 =  351/36, so we have:

364/36 - 351/36

=  13/36

Please read the explanation... it always helps... i promise...

Step-by-step explanation:

Alrighty the circle circumference states that... c = 2r pi

we need to find the radius which is always half of the diameter.... so 34/2=17

the radius is 17... now all we have to do is substitute 17 into the circumference formula...

(2)17 pi = 34pi OR 106.81

or you can do Diameter multiplied by pi since the diameter is basically the radius multiplied by two... there are multiple ways you could approach this problem...

i hope this helps!!!!!!!

The circumference of the circle is approximately 106.96 inches.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

The circumference C of a circle with diameter d is given by the formula:

C = πd

Substituting the given value of diameter, we get:

C = π(34) = 34π

Using an approximation of π as 3.14, we can calculate the approximate circumference as:

C = 34 × 3.14 = 106.96 inches

Therefore,

The circumference of the circle is approximately 106.96 inches.
