What is the length of AB?

A. 2
B. 6
C. 8
D. 4

Answer:

[(2*8) + 3] *4 = 76

[2*(8 - 3)]*4 = 40

Step-by-step explanation:

Los paréntesis ( ), corchetes [ ] y llaves {} son símbolos de agrupación que indican el orden de las cuatro operaciones aritméticas básicas (suma, resta, multiplicación y división). Las reglas del orden de operaciones establece que se debe realizar primero el cálculo dentro de los símbolos de agrupación.

En otras palabras, la jerarquía de operaciones es el orden en el que hay que realizar las distintas operaciones, ya que unas tienen prioridad frente a otras. Y establece primero debes empezar por resolver los paréntesis, luego los corchetes y finalmente las llaves. Es decir, cuando haya símbolos de agrupación dentro de símbolos de agrupación, calcula de adentro hacia afuera. Esto es, empieza simplificando los símbolos de agrupación en el centro.

Para obtener 76, se pueden realizar la siguiente operación combinada:

[(2*8) + 3] *4

Aplicando lo anteriormente mencionado de la jerarquía de operaciones, comienzas por resolver el paréntesis:

[16 + 3]*4

Ahora, resolviendo el corchete:

19*4

Finalmente, resolviendo la multiplicación:

19*4= 76

Entonces [(2*8) + 3] *4 =76

Para obtener 40, se pueden realizar la siguiente operación combinada:

[2*(8 - 3)]*4

Comenzando a resolver el paréntesis:

[2*5]*4

Ahora, resolviendo el corchete:

10*4

Finalmente, resolviendo la multiplicación:

10*4= 40

Entonces [2*(8 - 3)]*4 = 40

Answer:

The answer is 135

Step-by-step explanation:

all angles in a triangle equal to 180.

so, 25+22= 45

then, 180-45= 135

the missing angles measure is 135 degrees

Step-by-step explanation:

The total expenses stay the same at $92,039.

The income changes to 12,000 × $35 = $420,000.

So the profit is $420,000 − $92,039 = $327,961.

Answer:c

c = - 15

Step-by-step explanation:

Simplifying

19c + 31 = 26c + -74

Reorder the terms:

31 + 19c = 26c + -74

Reorder the terms:

31 + 19c = -74 + 26c

Solving

31 + 19c = -74 + 26c

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-26c' to each side of the equation.

31 + 19c + -26c = -74 + 26c + -26c

Combine like terms: 19c + -26c = -7c

31 + -7c = -74 + 26c + -26c

Combine like terms: 26c + -26c = 0

31 + -7c = -74 + 0

31 + -7c = -74

Add '-31' to each side of the equation.

31 + -31 + -7c = -74 + -31

Combine like terms: 31 + -31 = 0

0 + -7c = -74 + -31

-7c = -74 + -31

Combine like terms: -74 + -31 = -105

-7c = -105

Divide each side by '-7'.

c = 15

Simplifying

c = - 15

Answer:

5 units

Step-by-step explanation:

Since the y value doesn't change, and the x value changes by 5 units, we can conclude that the distance between the points is 5 units.

Answer:

the sum will be negative

The sum will always be negative because the positive number would have to be larger than the negative for the outcome to be positive.

Answer:  to get the equation needed to graph the equation, divide tach term by -3 to isolate y. The  slope-intercept equation becomes

y = -7x/3 + 7

Step-by-step explanation:

Use the y-intercept to plot 7 on the y axis then plot a point down 7 and 3 to the right  (3,0) and draw the line through those points.

Step-by-step explanation:

The running back's total yardage is 21 yards

From the question we are given the following parameters

Distance travelled in the first half of the game is 9 yards

Distance travelled in the second half of the game is 12 years

In order to determine the running back's total yardage, we will take the sum of the distance travelled as shown

Total distance travelled = 9 yards + 12 yards

Total distance travelled = 21 yards

Hence the running back's total yardage is 21 yards

Answer:254 days

Joanne and Ed Greenwood built a new barn with an attached arena. To finance the loan, they paid $1,326 interest on $47,600 at 4%. What was the time, using exact interest? (Do not round intermediate calculations. Round up your answer to the nearest day.)

Step-by-step explanation

Note that

Interest is represented by I=1326

The principal is represented by P=47,600

Rate is R =4%

And Time is year

Interest is calculated using the formulae,

I =PRT/100

From the above formulae, time can be calculated as

T=100I/PR

T= 100×1326/(47600×4)

T= 132600/190400

T= 0.6964 years

To convert to days, multiply by 365(since those no of days make a year)

T= 0.6964×365=254 days

This was approximated to the nearest day

Answer is 254 days

Answer:156

The intensity level is moderate

In one second Corey's heart will beat 3 times.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is Corey's heart beats 26 times in 1/6 minutes.

Assume that her heart beats [x] times in 1 second. Then -

1/6 of minute = 1/6 x 60 = 10 seconds

In 10 seconds, her heart beats 26 times

So, in one second, her heart will beat (26/10) = 2.6 times = 3 times (approx.).

Therefore, in one second Corey's heart will beat 3 times.

Answer:

R- 73°

S- 73°

W- 138°

Step-by-step explanation:

Every triangle is 180°.

So 65+42=107

180-107=73

So that's the triangle to the right.

Now the other one is identical.

So we know the line w is on is 180°

On the corner w is on it took up 42°

So 180-42= 138° (which is 'w')
