Answer:

A) 5 notebooks, 10 pencils

Step-by-step explanation:

n = notebook

p = pencil

1.97n + 1.16p = 21.45

A)✅

1.97(5) + 1.16(10) = 21.45

9.85 + 11.6 = 21.45

21.45 = 21.45

B) ❌

1.97(3) + 1.16(12) = 21.45

5.91 + 13.92 = 21.45

19.83 = 21.45

Answer:

y = 33.94 mm

x = 19.80 mm

Step-by-step explanation:

Because AC = CB, then ∠ABC = 45°

cos ∠ABC = 24/y

cos 45° = 0.7071 = 24/y

y = 33.94 mm

EF/BC = x/y

14/24 = x/33.94

24x = 475.16

x = 19.80 mm

Answer:

x = 8 cm

Step-by-step explanation:

Using the Pythagorean theorem:

x² = 10² - 6² = 100 - 36 = 64

x = √64 = 8

The length or value of x in the given right angle triangle will be 8 cm.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

The triangle is a highly common shape that we deal with on a daily basis. For instance, the right-angle triangle is frequently used to estimate the height of towers.

In a triangle, the sum of all three angles is 180°.

Given a right-angle triangle with

Hypotaneous = 10cm

Perpendicular = 6 cm

Base = x ( need to find out).

By Pythagoras theorem,

Base² = Hyp² - Perp²

Base² = 10² - 6²

Base² = 100 - 36

Base = √(64) = 8 cm

Hence the base of the given triangle will be 8 cm.

Step-by-step explanation:

Given:

The length of the rectangle is:

[tex]l=x^2-x+3[/tex]

The width of the rectangle is:

[tex]w=4x+1[/tex]

To find:

The area of the given rectangle in the simplest form.

Solution:

We know that, the area of a rectangle is:

[tex]A=l\times w[/tex]

Where, l is the length and w is the width of the rectangle.

Using the above formula, the area of the given rectangle is:

[tex]A=(x^2-x+3)\times (4x+1)[/tex]

[tex]A=x^2(4x)+x^2(1)-x(4x)-x(1)+3(4x)+3(1)[/tex]

[tex]A=4x^3+x^2-4x^2-x+12x+3[/tex]

[tex]A=4x^3-3x^2+11x+3[/tex]

Therefore, the area of the given rectangle is [tex](4x^3-3x^2+11x+3)[/tex] sq. units.

Answer:

a. The probability that a particular student arrives by car is [tex]\frac{1}{20}[/tex] = 0.05, which equals 5%.

b. The probability that a particular student walks to school is [tex]\frac{3}{10}[/tex] = 0.3, which equals 30%.

c. The probability that a particular student does not walk to school is [tex]\frac{7}{10}[/tex] = 0.7, which equals 70%.

d. The probability that a particular student does not walk or come by car is [tex]\frac{13}{20}[/tex] = 0.65, which equals 65%.

Step-by-step explanation:

Probability is the greater or lesser possibility of a certain event occurring. In other words, probability establishes a relationship between the number of favorable events and the total number of possible events. Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.

[tex]P(A)=\frac{number of favorable cases}{number of possible cases}[/tex]

In this case, the number of possible cases is always the same, which is equal to the total number of students. So the number of possible cases is 320 students. The number of favorable cases varies as follows:

a. Number of favorable cases= number of students that arrive by car= 16

So: [tex]P(A)=\frac{16}{320}[/tex]

P(A)=[tex]\frac{1}{20}[/tex] = 0.05, which equals 5%

The probability that a particular student arrives by car is [tex]\frac{1}{20}[/tex] = 0.05, which equals 5%.

b. Number of favorable cases= number of students that walk to school= 96

So: [tex]P(A)=\frac{96}{320}[/tex]

P(A)=[tex]\frac{3}{10}[/tex] = 0.3, which equals 30%

The probability that a particular student walks to school is [tex]\frac{3}{10}[/tex] = 0.3, which equals 30%.

c. Number of favorable cases= number of students that do not walk to school = 320 students - number of students that walk to school= 320 students - 96 students= 224 students

So: [tex]P(A)=\frac{224}{320}[/tex]

P(A)=[tex]\frac{7}{10}[/tex] = 0.7, which equals 70%

The probability that a particular student does not walk to school is [tex]\frac{7}{10}[/tex] = 0.7, which equals 70%.

d. Number of favorable cases= number of students that do not walk or come by car= 320 students - number of students that walk to school - number of students that arrive by car= 320 students - 96 students - 16 students= 208 students

So: [tex]P(A)=\frac{208}{320}[/tex]

P(A)=[tex]\frac{13}{20}[/tex] = 0.65, which equals 65%

The probability that a particular student does not walk or come by car is [tex]\frac{13}{20}[/tex] = 0.65, which equals 65%.

h = 6 feet

Step-by-step explanation:

Given that,

The volume of a right rectangular prism = 192 cubic feet

The area of the base of the pool is 32 square feet.

We need to find the height of the prism. We know that the volume of a right rectangular prism is given by :

[tex]V=lbh[/tex]

We have, V = 192 cubic feet, lb = 32 sq feet

So,

[tex]h=\dfrac{V}{lb}\\\\h=\dfrac{192}{32}\\\\=6\ feet[/tex]

So, the height of the prism is equal to 6 feet.
