What type of polynomial is this? 6x + 3
Answer:
Binomial
Step-by-step explanation:
A binomial has two terms. Each term consists of a coefficient, and a variable with an exponent. We can see the two terms:
6x (the exponent would be 1) + 3 (the variable and exponent would be x to the 0. Any variable to the power of 0 is equal to 1, which is why it's not shown)

Hi so i have a question that is..... A pool is in the shape of a right rectangular prism and has a volume of 192 cubic feet. The area of the base of the pool is 32 square feet. Could anyone help me?
Answer:
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.
Rian is packing toys in boxes. Each box is 3 inches by 4 inches by 6 inches. Each toy takes up 65% of the volume of the box, and the rest of the volume of the box is filled with foam packing beads. What is the volume, in cubic inches, of the foam packing beads used to fill each box
9514 1404 393
Answer:
25.2 in³
Step-by-step explanation:
The volume of the box is ...
V = LWH
V = (3 in)(4 in)(6 in) = 72 in³
__
65% of the box is filled with a toy, so the remaining 100% -65% = 35% is filled with packing beads. The volume of packing beads required is ...
0.35 × 72 in³ = 25.2 in³
25.2 in³ of foam packing beads are used to fill each box.
Factor the expression completely.

Help how do I solve for x and y when they are they on the same corresponding side
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

Joanna went school supply shopping. She spent $21.45 on notebooks and pencils. Notebooks cost $1.97 each and pencils cost $1.16 each. She bought a total of 15 notebooks and pencils. How many of each did she buy?
A.
5 notebooks; 10 pencils
B.
3 notebooks; 12 pencils
C.
8 notebooks; 7 pencils
D.
10 notebooks; 5 pencils
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

Show work please! Herald is keeping track of eagles. To do so, he put tags on 25 eagles and released them.
Later, he catches 120 eagles; 16 eagles were tagged. Find the best estimate for the Eagle
population?
Answer:
188
Step-by-step explanation:
16/120=0.133
0.133 times 100=13.3%
this means 25 eagles is only 13.3% of the population
therefore 25/0.13=188

There are 320 students in a school. 16 come to school by car. 96 walk to school. Estimate the probability that a particular student: a arrives by car b walks to school c does not walk to school d does not walk or come by car.
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%.

Find x in each triangle
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.
What is a triangle?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.

Write an expression to represent the area of the rectangle below in simplest form.
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.
