Answer:
[tex]\huge\boxed{\texttt{The number is 27.}}[/tex]
Step-by-step explanation:
In order to find the number we need to set up an equation where we represent the unknown number as a variable. I'll call it [tex]n[/tex].
5 times a number can be represented as [tex]5n[/tex].
18 more than that can be represented as [tex]5n+18[/tex].
We know it equals 153, so [tex]5n+18=153[/tex].
We can solve for n by reversing the equation until we have n isolated on one side.
Subtract 18 from both sides:
[tex]5n=135[/tex]
Divide both sides by 5:
[tex]n = 27[/tex]
So our unknown number is 27.
Hope this helped!

The dimensions of a rectangular prism are 24 ft x 20 ft x 15 ft. What is the surface area
Answer:
2280 ft^2
Step-by-step explanation:
A rectangular prism has 6 faces. Each pair of opposite faces is congruent.
surface area = 2LW + 2LH + 2WH
surface area = 2(24 ft)(20 ft) + 2(24 ft)(15 ft) + 2(20 ft)(15 ft)
surface area = 960 ft^2 + 720 ft^2 + 600 ft^2
surface area = 2280 ft^2
How do you know whether two quantities x and y are proportional?
1. Every ratio yx for related pairs of x and y is equivalent.
2. Every sum x + y is the same for related pairs of x and y.
3. Every x term is a multiple of the previous term.
4. Every difference x – y is the same for related pairs of x and y please help me
Answer:
The correct answer is:
1. Every ratio yx for related pairs of x and y is equivalent.
Step-by-step explanation:
Proportion is defined as the relationship between two quantities. When one quantity changes the other is also changes.
For two quantities y and x when we say that both are proportional then t can be written as:
y∝x
Removing the proportionality symbol introduces a constant which is the ratio of y and x.
[tex]\frac{y}{x} = k[/tex]
This ratio of y and x, i.e. k is equivalent for all related pairs of x and y.
Hence,
The correct answer is:
1. Every ratio yx for related pairs of x and y is equivalent.

Sara compra 3 naranjas a Q 2.00 cada una. Compra un melón a
Q 12.00 y quiere comprar 4 manzanas, tomando en cuenta que la
docena de manzanas cuesta Q 24.00. ¿Cuánto gastó en total por las 3
naranjas, el melón y las 4 manzanas?
Respuesta:
29.00
Explicación:
una naranja 3.00
un melón 12.00
una manzana 2.00 (porque una docena equivale 12 artículos; 24/12 es 2)
tres naranjas 3(3.00) = 9.00
un melón 12.00
cuatro manzanas 4(2.00) = 8.00
9.00 +12.00 +8.00

Answer:
C.195312
Step-by-step explanation
The sum of geometric sequence 2,10,50... up to 8 terms is 195312. Therefore, option C is the correct answer.
The given geometric sequence is 2+10+50+250+.....
What is the sum of the geometric sequence formula?Sum of the geometric sequence is S = a + ar + ar² +....+ [tex]ar^{n-1}[/tex].
The first term of the series is a and the common ratio is r.
The sum of the geometric sequence formula is [tex]S_{n} =\frac{a(r^{n} -1)}{(r-1)}[/tex] .
Now, a=2
To find r,
r = 10/2
r = 5 and n = 8
S = 2 ([tex]5^{8}[/tex]- 1) / (5 - 1)
S = 2(390625 - 1) / 4
S = (390624) / 2
S = 195312
Therefore, the sum of geometric sequence 2,10,50... up to 8 terms is 195312.

If a gun fires 88 rounds per minute, how many rounds would it fire in 45 minutes?
Answer:
3960
Step-by-step explanation:
1minute = 88rounds
45minutes = xrounds
1/45 = 88/x
45(88)= 3960
3960/1 = 3960
x = 3960
The gun fires 3960 rounds in 45 minutes.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
Let x rounds would it fire in 45 minutes
As per the situation, we can write the proportion would be as:
1 minute : 88 rounds = 45minutes : x rounds
⇒ 1/88 = 45/x
Apply the cross-multiplication, and we get
⇒ x = 45(88)
⇒ x = 3960
This means a gun fires 3960 rounds in 45 minutes.

Find the equation of the line that has a slope of 2
and passes through the point (5, -8). Write the
equation in point-slope form.
Answer:
The equation in the point-slope form will be:
[tex]y-(-8) = 2 (x-5)[/tex]
Step-by-step explanation:
The point-slope form of an equation is written as:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope, and (x₁, y₁) is a point on the line.
Now, we will substitute the values of m and (x1, y1) in the given equation. Here,
m=2
and
(x1, y1) = (5, -8)
x1 = 5
y1 = -8
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-(-8) = 2 (x-5)[/tex]
Therefore, the equation in the point-slope form will be:
[tex]y-(-8) = 2 (x-5)[/tex]
In 1992, Disney created a one-of-a-kind special pin. Each year, the pin’s value appreciates by a constant amount. In 1997, the pin was valued at $350. In 2002, it was valued at $600. Let x be the number of years since 1992 and y be the value of the pin in dollars. Write a linear equation in slope-intercept form that models this situation.
Answer:
[tex]y = 50x + 50[/tex]
Step-by-step explanation:
Given
x = years since 1992.
y = value of pin
This means that
[tex]x = 1[/tex] ----- in 1992
[tex]x_1 = 6[/tex]; [tex]y_1 = 350[/tex] ---- in 1997
[tex]x_2 = 11;[/tex] [tex]y_2 = 600[/tex] ---- in 2002
Required
Determine the line equation in slope intercept form
First, we need to determine the slope (m) of the line
[tex]m = \frac{y_2 - y_1}{x_2- x_1}[/tex]
[tex]m = \frac{600 - 350}{11- 6}[/tex]
[tex]m = \frac{250}{5}[/tex]
[tex]m = 50[/tex]
The equation is then calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
Recall that
[tex]x_1 = 6[/tex]; [tex]y_1 = 350[/tex]
[tex]m = 50[/tex]
So, we have:
[tex]y - 350 = 50(x - 6)[/tex]
[tex]y - 350 = 50x - 300[/tex]
[tex]y = 50x - 300 + 350[/tex]
[tex]y = 50x + 50[/tex]

What do we mean when we say like terms? what do we mean when we say combining like terms? how do polynomials demonstrate the closure property under addition and subtraction?
1. like terms are basically terms that have the same variables and powers.
2. We call terms "like terms" if 2 numbers have the same variables.
3. Polynomials form a system similar to the system of integers, in that polynomials are closed under the operations of addition, subtraction, and multiplication. Polynomials will be closed under an operation if the operation produces another polynomial. Polynomials are closed under subtraction.
