What is the volume of a triangular pyramid that is 6 inches tall and has a base area of 7 square inches ?

Answer:

5

Step-by-step explanation:

To find the distance between two points, use the distance formula, [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, while the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. Thus, substitute the x and y values of the given points into the appropriate places of the formula and solve:

[tex]d = \sqrt{((-1)-(3))^2+((4)-(7))^2} \\d = \sqrt{(-1-3)^2+(4-7)^2} \\d = \sqrt{(-4)^2+(-3)^2} \\d = \sqrt{16 + 9 } \\d = \sqrt{25} \\d = 5[/tex]

Thus, the distance is 5 units.

Answer:

basicly the -6 is the x and the 5 is the y

but the h is 7.8

Step-by-step explanation:

Answer:

[tex]x = 4\\y = 9[/tex] hours

Step-by-step explanation:

Given -

x represents the number of hours lifeguarding and y represents the number of hours landscaping

[tex]x+ y = 13[/tex] -----Eq ( 1 )

and

[tex]20 * x + 10 * y = 170[/tex] -----Eq ( 2 )

Substituting the value of [tex]x = 13-y[/tex] in equation 2, we get -

[tex]20* (13 - y) + 10 y = 170[/tex]

[tex]260 - 20 y + 10 y = 170\\10y = 90\\y = 9[/tex]

[tex]x = 13-9 = 4[/tex]

Answer:

In the long run if one day is rainy there is frequency of 2/5 that other two days will also be rainy.

Step-by-step explanation:

A matrix is formed to classify the weather conditions. It is given that if one day is sunny then there is likely chance that the next day will be cloudy, but if one day is rainy then there is 60% chance that next day will be same. To identify the possibility of next two days we create probability matrix;

Probability (P) = [tex]\left[\begin{array}{ccc}0&\frac{1}{2} &\frac{1}{2} \\\frac{1}{4} &\frac{1}{2} &\frac{1}{4} \\\frac{1}{4} &\frac{1}{4} &\frac{1}{2} \end{array}\right][/tex]

After solving for probability we get a fraction of 2/5

The answer is 6.252 pounds.

2 1/2 as a decimal is 2.5, and 15 ounces is equal to 0.938 pounds. Since there are 4 notebooks, you multiply 0.938 by 4, which is 3.752. Now, you just add 2.5+3.752=6.252

Answer:

230 were sold at the door

170 were sold in advance

Step-by-step explanation:

x=at door y=in advance

x+y=400

3x+2y=1030

y=-x+400

2y=-3x+1030

y=-3/2x+515

-x+400=-3/2x+515

x=230 y=170

Answer:

17x + 44

Step-by-step explanation:

Start by combining like-terms: 10x + 7x = 17x ; 30 + 14 = 44

Left with: 17x + 44

Answer:

Remove the parentheses

10x + 30 + 7x + 14

Add the like terms

Answer:

14/29

Step-by-step explanation:

The probability that a child chosen at random from the class likes math but not history is 14/29  or 0.4827.

It is given that the in a class of 29 children, 15 likes history and 21 like math.

It is required to find the probability that a child chosen at random from the class likes math but not history if they all like at least one of the two subjects.

It is defined as the diagram that shows a logical relation between sets.

The Venn diagram consists of circles to show the logical relation.

We have:

Total students in a class = 29

First we have to find the number of students who likes both subject for this we have draw a Venn diagram shown in the picture.

From the Venn diagram number of students who likes both = 7

And number of students likes only math = 14

Hence, the probability will be:

[tex]p = \frac{14}{29}[/tex]   ( because total number of students is 29)

or P = 0.4827 or 48.27%

Thus, the probability that a child chosen at random from the class likes math but not history is 14/29  or 0.4827.
