Find the lateral surface area and volume of the solid object in picture
Answers
Notice that s stands for the slant height of the pyramid, and this height is the height of each one of the lateral triangular faces.
We will need to use the next formulas
[tex]\begin{gathered} A_{\text{hex}}=\frac{3\sqrt[]{3}}{2}a^2\to\text{Area of a regular hexagon (a is one of its sides)} \\ A_{\text{tri}}=\frac{bh}{2}\to\text{Area of a triangle} \end{gathered}[/tex]Therefore, the surface area is
[tex]\begin{gathered} A_{\text{figure}}=A_{\text{hex}}+6\cdot A_{\text{tri}}=\frac{3\sqrt[]{3}(3)^2}{2}+6\cdot\frac{(3\cdot10.3)}{2} \\ =\frac{27\sqrt[]{3}}{2}+92.7 \\ \Rightarrow A_{\text{figure}}=\frac{27\sqrt[]{3}}{2}+92.7 \\ \Rightarrow A_{\text{figure}}\approx23.4+92.7=116.1 \\ \Rightarrow A_{\text{figure}}=116.1 \end{gathered}[/tex]Lateral Area=116.1 m^2
As for the volume, the volume of a regular pyramid is
[tex]V=\frac{A_{\text{base}}\cdot h}{3}[/tex]In our case,
[tex]V=\frac{3\sqrt[]{3}a^2}{2}\cdot\frac{h}{3}=\frac{\sqrt[]{3}}{2}a^2h[/tex]Therefore,

The ratio of chocolate chip cookies to oatmeal raisin cookies in the cookie box is 1 to 4. If there are 2 chocolate chip cookies in a cookie box, how many the total chocolate chip and oatmeal raisin cookies are there in the cookie box?
Answers
Based on the given ratio, the total number of chocolate chip and oatmeal raisin cookies in the cookie box is 10.
What is the ratio?The ratio refers to the numerical relationship that one value or number bears to another.
Ratios are fractional values, showing how much a value is contained in another, or in relation to another.
Ratios are depicted using the ratio sign (:), fractions, decimals, or percentages, like proportions.
The ratio of chocolate chip cookies to oatmeal raisin cookies = 1:4
The sum of ratios = 5 (1 + 4)
The number of chocolate chip cookies in the cookie box = 2
Using the above ratio, there will be 8 oatmeal raisin cookies, that is 2/1 x 4
The total number of cookies (both types) in the cookie box = 10 (2/1 x 5).
Thus, we can conclude that based on the relative sizes of both cookies, the total number in the box is 10.

The mean of the number of shoes according to the obtained results is; 8.49.
The median of the number of pairs of shoes obtained is; 9.
What is the mean and median of the frequency distribution?It follows from the complete task content that the mean and median of the data set are to be evaluated;
Since the mean is the average of all obtained data values, it follows from the mean formula;
Mean = Sum Total/Total Frequency
Mean = { ( 8 × 4 ) + ( 4 × 5 ) + .......+ (13 × 4) } / 65
Mean = 552/65
Mean = 8.49.
Also, the median of the set of 65 data values can be guessed to be the 33rd term.
On this note, the data value which corresponds to a cumulative frequency of 33 upon orderly arrangement is the median term.
Hence, since; 8 + 5 + 4 + 4 + 7 = 28; Hence, upon addition of 14, we have; 42.
Therefore, the median of the number of pairs of shoes is; 9 pairs of shoes.

Because she’s buying online, she must pay a shipping fee of $10. Josie wants to spend $150 or less. How many sets of dishes can Josie buy?

subtract 10 from both sides:
35d + 10 - 10 = 150 - 10

suppose that 15 inches of wire cost 60 cents. at the same rate, how much (in cents) will 11 inches of wire cost
Answers
The cost of 11 inches of wire will be 44 cents
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
The 15 inches of wire costs 60 cents, so the cost of 1 inch of wire is;
Rate = 60/15 =4 cents
So the cost of 1 inch of wire which is the rate of 4 cents.
Now we have to find the cost (in cents) of 11 inches wire.
We know the cost of 1 inch of wire cost 4 cents so the cost of 11 inches of wire is;
= Total inches of wire x Price of 1 inch of wire
= 4 x 11

What is direct variation?Any time one quantity directly affects the other, such as when one quantity rises relative to the other and vice versa, there is a direct variation between the two variables. It is the relationship between two variables where one of the variables is a fixed multiple of the other. Since the two variables are directly correlated, they are also known as directly proportional.
There are two kinds of proportionalities: direct variation and inverse variation. When two quantities are multiplicatively connected by a constant, the relationship is said to be proportional. In a direct variation, the ratio of the two quantities stays the same, whereas in an inverse variation, the product of the two quantities stays the same.

The sum of the weight of the empty box and the 940 feathers is approximately [tex]5.90 \times {10}^{ - 1} [/tex] kg.
What is a scientific notation?A number is expressed using scientific notation when it contains a number larger than 1 but less than 10, that multiplies a power of 10
The empty weight of the box = 56.7 grams
The number of feathers added = 940 feathers
Mass of one feather (unit weight) = 0.000567 kilogram
The total weight of the box with the 940 feathers is found as follows;
56.7 grams = 0.0567 kilograms
Mass of the empty box in kilograms = 0.0567 kilograms
Total mass of the 940 feathers 0.000567 × 940 = 0.53298 kilograms
The total weight of the box with the 940 feathers inside is; 0.0567 kilograms + 0.53298 kilograms = 0.58968 kilograms
The total weight of the box and the feathers = 0.58968 kilograms =

From the table of ordered pairs, it is observed that the zeros of the quadratic function are at x = 6 and x = 8. The zeros are the points where the y value of the function becomes zero.
An equation of the function in the standard form is given by :
y = (x - 6)(x - 8)
⇒y = x (x - 8) - 6 (x - 8)

What is the image of the point ( − 1 , 2 ) after a rotation of 270 counterclockwise about the origin?
Answers
What is the y-intercept? Select the correct choice below and fill in any answer boxes within your choice.
Answers
We have the relation:
y = 4x + 3
Since the slope (4) and the y-intercept (3) were already found, we need now to graph this line.
In order to do so, we can find two points belonging to this line and then draw a line that passes through those points.
The first point can be (0, 3), since we know that the y-intercept is 3, i.e., y = 3 for x = 0.
Now, to find a second point we can choose a value for x, let's say x = 1, and use it in the equation of the line to find the corresponding value of y:
y = 4x + 3 , x = 1
y = 4 * 1 + 3
y = 4 + 3
y = 7
So, (1, 7) is another point we can use.
Now, we can select the second button on the toolbox to draw a line through the points (0, 3) and (1, 7):

When Janet has $50 in a savings account that earns 10% annually, the interest is $15.
How to calculate the interest?It should be noted that the interest is the extra amount that's given for keeping money for a specified period of time. Interest is the payment of a sum over and above the original amount owed by a lender or deposit-taking financial institution to a depositor or lender, at a set rate.
The formula for calculating interest is given as:
Interest = PRT / 100
where P = Principal. = $50
R = rate = 10%
T = Time = 3
Interest = PRT / 100
Interest = (50 × 10 × 3) / 100.
Interest = 1500 / 100
Interest = $15
The interest is $15.
