2. Samuel used clay to make a diorama of the pyramids in Ancient Egypt. He made two triangular pyramids and three rectangular pyramids. How much clay did he use to create all the pyramids?

Answer:

6 square units

Step-by-step explanation:

In oder to do this, you need graph paper to make it easier and then mark your graph paper with the quadrants.

I got 3 unites for the height and 4 units for the base

4 x 3 = 12 square units

however the formula for a triangle is Ab/2

so divide 12/2 = 6

So its 6 square units

Given:

A directed line segment begins at F(-8, -2), ends at H(8, 6), and is divided in the ratio 8 to 2 by G.

To find:

The coordinates of point G.

Solution:

Section formula: If a point divide a line segment with end points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in m:n, then the coordinates of that point are

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

Point G divide the line segment FH in 8:2. Using section formula, we get

[tex]G=\left(\dfrac{8(8)+2(-8)}{8+2},\dfrac{8(6)+2(-2)}{8+2}\right)[/tex]

[tex]G=\left(\dfrac{64-16}{10},\dfrac{48-4}{10}\right)[/tex]

[tex]G=\left(\dfrac{48}{10},\dfrac{44}{10}\right)[/tex]

[tex]G=\left(4.8,4.4\right)[/tex]

Therefore, the coordinates of point G are (4.8, 4.4).

10 lunches

Step-by-step explanation:

$47-$7=$40

40/4=10

Hello, 928747!

So we are trying to find how many boxed lunches Janie ordered.

Each box is $4.00 and the total cost is $47.00 + delivery fee of $7.00

So to find this, we will first subtract the delivery fee because that does not count towards the lunches.

47 - 7 = 40

So the boxed lunches cost $40.00

To find how many Janie ordered, we will divide 4 by 40

40 ÷ 4 = 10

So Janie bought 10 boxed lunches.

The equation would be (47 - 7) ÷ 4

Option A is correct, the value of y is 57 degrees in the triangle.

We have to find the value of y in the given triangle.

Initially let us find the adjacent angle or interior angle which is adjacent to 114 degrees.

We know the straight line has an angle of 180 degrees

114+x=180

x=66 degrees.

By angle sum property the sum of three angles is 180 degrees.

66+y+y=180

66+2y=180

Subtract 66 from both sides:

2y=180-66

2y=114

Divide both sides by 2:

y=57 degrees

Hence, the value of y is 57 degrees in the triangle.

Given:

[tex]\sqrt{2}=1.414[/tex]

To find:

The value of [tex]\sqrt{50}+\sqrt{72}[/tex].

Solution:

We have,

[tex]\sqrt{50}+\sqrt{72}[/tex]

It can be rewritten as

[tex]=\sqrt{2\times 25}+\sqrt{2\times 36}[/tex]

[tex]=\sqrt{2}\times \sqrt{25}+\sqrt{2}\times \sqrt{36}[/tex]        [tex][\because \sqrt{ab}=\sqrt{a}\sqrt{b}][/tex]

[tex]=5\sqrt{2}+6\sqrt{2}[/tex]

[tex]=11\sqrt{2}[/tex]

Putting [tex]\sqrt{2}=1.414[/tex], we get

[tex]=11(1.414)[/tex]

[tex]=15.554[/tex]

Therefore, the value of given expression is 15.554.

The probability that 15 or more students in the sample are left-handed handed is 0.0752

(a) Why L can be a binomial distribution

From the question, we understand that 11% of the students are left-handed; this means that 89% are not left-handed

This, in other words means that:

For each observation, the student is either left-handed or not left-handed

Hence, the distribution can be represented by a binomial distribution

(b) The probability that 15 or more are left-handed

The sample size is given as:

[tex]\mathbf{n = 100}[/tex]

And the proportion is

[tex]\mathbf{p = 11\%}[/tex]

The mean of the dataset is:

[tex]\mathbf{\mu = np}[/tex]

[tex]\mathbf{\mu = 100 \times 11\%}[/tex]

[tex]\mathbf{\mu = 11}[/tex]

The standard deviation of the dataset is:

[tex]\mathbf{\sigma = \sqrt{\mu(1- p)}}[/tex]

So, we have:

[tex]\mathbf{\sigma = \sqrt{11 \times (1- 11\%)}}[/tex]

[tex]\mathbf{\sigma = \sqrt{11 \times 89\%}}[/tex]

[tex]\mathbf{\sigma = \sqrt{9.79}}[/tex]

[tex]\mathbf{\sigma = 3.13}[/tex]

So, the probability is represented as:

[tex]\mathbf{P(x \ge 15)}[/tex]

Using continuity correction, we have:

[tex]\mathbf{P(x \ge 15) = P(x \ge 15.5)}[/tex]

Calculate the z-score for x = 15.5

[tex]\mathbf{z =\frac{x - \mu}{\sigma}}[/tex]

So, we have:

[tex]\mathbf{z =\frac{15.5 - 11}{3.13}}[/tex]

[tex]\mathbf{z =\frac{4.5}{3.13}}[/tex]

[tex]\mathbf{z =1.438}[/tex]

The probability is then calculated as:

[tex]\mathbf{P(x \ge 15) = P(z \ge 1.438)}[/tex]

Using z-tables of probabilities, we have:

[tex]\mathbf{P(x \ge 15) = 0.075217}[/tex]

Approximate

[tex]\mathbf{P(x \ge 15) = 0.0752}[/tex]

Hence, the probability is 0.0752

Answer:

Kitten is 15 seconds and dog is 10 seconds

In work and time the time taken is inversely proportional to the work done. Work and time is a concept to solve the problems of work related question in a given time.The kitten eats a sausage in 15 seconds  and puppy eats a sausage in 10 seconds.

In work and time the time taken is inversely proportional to the work done. Work and time is a concept to solve the problems of work related question in a given time

Puppy and kitten eats one sausage combined in 6 sec.

A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage.

Let puppy eats a sausage in [tex]x[/tex] seconds and kitten eats a sausage in [tex]y[/tex] seconds.

As Puppy and kitten eats one sausage combined in 6 sec.Thus,

[tex]\dfrac{1}{x} +\dfrac{1}{y} =\dfrac{1}{6}[/tex]

Let above equation is equation one.

A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage. Thus

[tex]\dfrac{1}{x} -\dfrac{1}{y}=\dfrac{1}{5}[/tex]

Put this value of [tex]x[/tex] in the  the equation one to get the value of y. Therefore,

[tex]\dfrac{1}{6} -\dfrac{1}{y}-\dfrac{1}{y}=\dfrac{1}{5}[/tex]

[tex]-\dfrac{1}{2y}=\dfrac{1}{5}-\dfrac{1}{6}[/tex]

[tex]-\dfrac{1}{2y}=-\dfrac{1}{30}[/tex]

[tex]y=15[/tex]

Thus the kitten eats a sausage in 15 seconds.

Put the value of y in equation one. thus,

[tex]\dfrac{1}{x} +\dfrac{1}{15} =\dfrac{1}{6}[/tex]

[tex]\dfrac{1}{x} =\dfrac{1}{6}-\dfrac{1}{15}[/tex]

[tex]\dfrac{1}{x} =\dfrac{9}{90}[/tex]

[tex]x=10[/tex]

Thus the puppy eats a sausage in 10 seconds.

Hence the kitten eats a sausage in 15 seconds  and  puppy eats a sausage in 10 seconds.
