Answer:
58° = measure of arc AC
Step-by-step explanation:
The measure of an angle formed by 2 chords is equal to 1/2 the sum of the measures of the intercepted arcs.
65 = (measure of arc AC + measure of arc BD)/2
= (measure of arc AC + 72)/2
130 = measure of arc AC + 72
58° = measure of arc AC

PLZ HELP, DUE TONIGHT!! Find the values of a and b such that f(x) is continuous at x=1
Answers
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 = -4What was Jackie's mistake?
Jackie is asked to find the value of x in the following set of complementary anges.
Answers
Answer:
x=37
Step-by-step explanation:
Complementary angles are a set of 2 angles that when added together, add up to 90. In order to solve for x, both angles have to be added and set to be equal to 90... but Jackie only used one of the angles, not both. The correct equation is: x+16+x=90
Answer:
Jackie forgot to add variable X

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.
Answers
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.

3^3 = 9
9 x 3.14 = 28.26(area of circle)
Now we multiply by height
28.26 x 5 = 141.3
Now we divide by 3 since its part for the formula of finding the cone's volume:
141.3 x 1/3(basically just dividing by 3) = 47.1
Now let's find the volume of the cylinder:
3^3 = 9, 9 x 3.14 = 28.26
28.26 x 14 = 395.64
Now let's add the given volumes:
395.64 + 47.1 = 442.74 cm^3 is your answer.

experimental probability that the next patient will be female and in
the age range 22-39? Enter your answer in simplified fraction
form.
Answers
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

find two numbers if their sum is 3/5 and their difference is 7 1/5
Answers
Answer:
A = 3 + 9/10
B = -(3 + 3/10)
Step-by-step explanation:
We have two numbers, A and B, such that:
A + B = 3/5
A - B = 7 + 1/5
To solve this, we first need to isolate one of the variables in one of the equations, I will isolate A in the first equation:
A = 3/5 - B
Now we can replace this in the other equation:
A - B = 7 + 1/5
(3/5 - B) - B = 7 + 1/5
3/5 - 2*B = 7 + 1/5
-2*B = 7 + 1/5 - 3/5
-2*B = 7 - 2/5 = 35/5 - 2/5 = 33/5
B = -(33/5)/2 = -33/10 = - 30/10 - 3/10 = -3 - 3/10 = -(3 + 3/10)
Now that we know the value of B, we can use the equation
A = 3/5 - B
To find the value of A:
A = 3/5 - ( -(3 + 3/10))
A = 3/5 + (3 + 3/10) = 6/10 + 3 + 3/10 = 3 + 9/10
The numbers are:
A = 3 + 9/10
B = -(3 + 3/10)

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
