Answer:
It would be 8x
Step-by-step explanation:
Since 10x and -2x are like terms, you can subtract -2x from 10x to get 8x.
10x - 2x = 8x
Answer:
8x
Step-by-step explanation:
Collect like terms by subtracting their coefficients.
(10 - 2)x = 8x
A layered birthday cake has three rectangular prism layers. The base layer measures 16 inches by 12 inches. Each layer is two inches smaller in width and depth as the previous layer. All of the layers are 4 inches tall. What is the volume of the cake? *
Answer:
The answer to your question is 732 in³
Step-by-step explanation:
Data
Rectangular prism layers
Base layer = 12 in x 10 in x 4 in
Second layer = 3 in smaller x 4 in
Volume = ?
Formula
Total volume = Volume of the base layer + Volume of the second layer
Total volume = length 1 x width 1 x height + length 2 x width 2 x height
Substitution
Total volume = 12 x 10 x 4 + (12 - 3)(10 - 3)(4)
Simplification
Total volume = 480 + (9)(7)(4)
Total volume = 480 + 252
Result
Total volume = 732 in³

A maple tree in the backyard of a home has a height of 0.75 meters. How many times as tall (t) is a nearby hickory tree that is 9 meters tall?
Answer: 12
Step-by-step explanation:
Since we are informed that a maple tree in the backyard of a home has a height of 0.75 meters.
To know the jow many times tall (t) is a nearby hickory tree that is 9 meters tall, we've to divide the height of the hickory tree by the height of the maple tree. This will be:
= 9meters / 0.75meters
= 12
Therefore, the hickory tree is 12 times tall as the maple tree.
PLZ HELP, DUE TONIGHT!! Find the values of a and b such that f(x) is continuous at x=1
Answer:
a = 2, b = -4Step-by-step explanation:
To make the given piecewise function continuous we need:
ax² - b = 6 and 5ax + b = 6 at x = 1It gives us the system:
a(1²) - b = 6 ⇒ a - b = 65a(1) + b = 6 ⇒ 5a + b = 6Sum of the two:
a - b + 5a + b = 6 + 66a = 12a = 2Then b is:
2 - b = 6b = -4Please help me with number 13 and 14 i really need help

A dentist has male and female patients that range in ages from 10
years old to 50 years old and up as shown in the table. What is the
experimental probability that the next patient will be female and in
the age range 22-39? Enter your answer in simplified fraction
form.
Answer:
2/15
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
Experimental probability is based on the result of an experiment that has been carried out multiples times
experimental probability that the next patient will be female and in
the age range 22-39 = females in the age range 22-39 / total number of patients
total number of patients = 56 / 420
To transform to the simplest form. divide both the numerator and the denominator by 28

Identify each congruence transformation that maps ABC to DEF
Answer:
A and F
Step-by-step explanation:
Option A works as a transformating, and option a is the same as potion f
The transformation given in option [1] is the correct transformation that maps ABC to DEF.
What is an expression? What is a triangle?A mathematical expression is a combination of terms separated by mathematical operators. For example : 2x + 3y + 6. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically - ∠x + ∠y + ∠z = 180°There are different types of triangles such as - equilateral triangle , scalene triangle , isosceles triangle etc.
We have two triangles as shown in the image.
The coordinates of a triangle ABC are shifted 6 units downward and then the complete figure is reflected across the y - axis.
Therefore, the transformation given in option [1] is the correct transformation that maps ABC to DEF.

La respuesta correcta para esta pregunta abierta es la siguiente.
Aunque no se anexaron opciones o incisos para contestar, podemos comentar lo siguiente.
Cada material en sus distintos estados de agregación, cambia de volumen de forma diferente, sin embargo todos lo hacen en cierta medida. A esta propiedad se le llama Estados de Agregación de la Materia.
Las substancias cambian su composición debido a la presión o al cambio de temperatura a la que son sometidos. A ese proceso se le conoce como el estado de agregación de la materia, cuando las moléculas y átomos que constituyen esa matera se ve sometido a una transformación en su composición.
Podemos reconocer comúnmente cuatro estados de transformación de la materia, que son, el estado de plasma, el estado gaseoso, el estado líquido y el estado sólido
The function f(t)=-16t^(2)+64 represents the height y (in feet ) of a water droplet t seconds after falling from an icicle. After how many seconds does the water droplet hit the ground
Answer:
The answer is two seconds
Step-by-step explanation:
Set the y to 0 as we are looking for the height when f(t) has hit the ground. Then factor and the two zeros of the function are -2 and 2. because the -2 is an answer that that cannot make sense for time in a real world scenario, the answer is the positive zero, or two. :-)
While vacationiong, you decided to go bungee jumping off a cliff into the river. Your height as a function of time is modeled by the function h(t)= -16t^2+16t+370, where t is time in seconds and h is the height in feet.
When did u hi the water? Round your answer to the nearest hundreth?
Answer:
5.33 Seconds
Step-by-step explanation:
This is because you have to do the quadratic equation and solve.
The time required to hi the water is 5.33 seconds.
What is a quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x as ax^2+bx+c=0 with a ≠ 0 . A quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2.
For the given situation,
The function is h(t)= -16t^2+16t+370
The roots of this function can be found by using the formula,
[tex]t=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]t=\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]
Here, a=-16, b=16, c=370
⇒ [tex]t=\frac{-16+\sqrt{16^{2}-4(-16)(370) } }{2(-16)}[/tex] or [tex]t=\frac{-16-\sqrt{16^{2}-4(-16)(370) } }{2(-16)}[/tex]
⇒ [tex]t=\frac{-16+\sqrt{23936} }{-32}[/tex] or [tex]t=\frac{-16-\sqrt{23936} }{-32}[/tex]
⇒ [tex]t=\frac{-16+154.712}{-32}[/tex] or [tex]t=\frac{-16-154.712}{-32}[/tex]
⇒ [tex]t=\frac{138.712}{-32}[/tex] or [tex]t=\frac{-170.712}{-32}[/tex]
⇒ [tex]t=-4.33[/tex] or [tex]t=5.33[/tex]
Time cannot be negative. So the value is 5.33.
Hence we can conclude that the time required to hi the water is 5.33 seconds.

The blueprint's scale is
1 inch : 9 feet. If the gym's
area is 52 square inches on the
blueprint, what is the actual
square footage of the gym?
The area of the actual gym
is_square feet.
Answer:
4212 square feet.
Step-by-step explanation:
If the blueprint's scale is 1 inch : 9 feet.
Square both sides
(1in)² = (9ft)²
1in² = 81ft²
Given the gym's area as 52 square inches, hence;
52in² = x
Divide both expressions
1/52 = 81/x
x = 52 * 81
x = 4212ft²
Hence the area of the actual gym is 4212 square feet.

What is the surface area, in square centimeters, of the
square pyramid?
Answer:
56
Step-by-step explanation:
To find the surface area, we need to find the area of all of the faces of this triangular prism. First, we figure out the area of a triangle which can be found by multiplying 1/2 x base x height ( 1/2 x 4 x 5 ) = 10. Since there are 4 faces that are triangles, we are going to multiply 10 x 4 = 40. Then, we find the area of the bottom which is a square and can be found by multiplying length x width (4 x 4) = 16. Finally, we add 40 + 16 = 56.
