There are 2 overlapping triangles here. If the vertical lines are parallel, then these triangles are similar, and corresponding sides occur in a fixed ratio. In particular, we have

2/3 = (2 + x) / (3 + (x + 7))

Solve for x :

2/3 = (2 + x) / (10 + x)

2 (10 + x) = 3 (2 + x)

20 + 2x = 6 + 3x

14 = x

A six-sided number cube is rolled twice.

Choose all of the dependent events.

A. The event that the first roll is a 3 or 4, and the event that the sum of the rolls is greater than 7.

B. The event that the first roll is greater than 3, and the event that the second roll is less than 3.

C. The event that the first rollis even, and the event that the second roll is also even.

D. The event that the first rollis odd, and the event that the sum of the rolls is 8.

E. The event that the first rollis odd, and the event that the second roll is a 1.

Answers

Answer: A and D

Step-by-step explanation:

Dependent events mean that one event depends on the outcome of the previous event.

A) If the first roll is a 3, and we want to sum more than 7 with the second roll, then the possible outcomes 5 and 6. Now if the first roll is 4, then the possible outcomes for the second event will be 4, 5 and 6. So you can see how the outcome space of the second event changes depending on the first event, so the events are dependent.

B) Here we do not have dependence, each event only depends on it's own outcome.

C) Again, both events only depend on it's own outcome, so the events are not dependent.

D) This is similar as the case for A, these events are dependent because is not the same if the outcome of the first event is 3, than if the outcome is 5 (the outcome needed for the second roll changes depending on the outcome of the first event)

E) Same as B and C, the events are independent.

The school cafeteria sells three different types of sandwiches: chicken, turkey,

and roast beef. Chicken sandwiches sell for $3, turkey sandwiches sell for

$3.50, and roast beef sandwiches sell for $4. The cafeteria makes 400

sandwiches in total, and, if all sandwiches are sold, the cafeteria will take in

$1375. If the cafeteria makes the same number of chicken sandwiches as it

does turkey sandwiches, how many of each type of sandwich does the school

make? (Hint: Write one equation for the number of sandwiches, one equation

for to amount of money all the sandwiches cost, and an equation that show the

number of chicken and turkey sandwiches are equal.)

No

Answers

Answer:

Number of chicken sandwiches = 150

Number of turkey sandwiches = 150

Number of roast beef sandwiches= 100

Step-by-step explanation:

We are told the school cafeteriat makes and sells 3 different types of sandwiches which are; chicken, turkey and roast beef.

Let chicken be x, turkey be y and roast beef be z.

We are told they make 400 sandwiches in total.

Thus;

x + y + z = 400

However, we are told that the cafeteria makes same number of chicken and turkey sandwiches.

Thus, x = y

Thus;

Total is now;

x + x + z = 400

2x + z = 400 - - - (eq 1)

Now,we are told that chicken, turkey and roast beef sandwiches are sold for $3, $3.5 and $4 respectively. Also that the total amount realized from sales is $1375.

Thus;

3x + 3.5y + 4z = 1375

Since x = y. Thus;

3x + 3.5x + 4z = 1375

6.5x + 4z = 1375 - - - (eq 2)

Let's make z the subject in eq 1.

Thus;

z = 400 - 2x - - - (eq 3)

Putting 400 - 2x for z in eq(2) gives us;

6.5x + 4(400 - 2x) = 1375

6.5x + 1600 - 8x = 1375

1600 - 1375 = 8x - 6.5x

225 = 1.5x

x = 225/1.5

x = 150

Putting 150 for x in eq 3 gives;

z = 400 - 2(150)

z = 400 - 300

Flossie needs 8 student and 8 staff for same number of staff members on each team.

Greatest common factor based ptroblem:

Number of student = 40 student

Number of staff members = 24 staff

Flossie wants there to be the same number of students and the same number of staff members on each team so, Flossie needs GCF

GCF of 40 student and 24 staff

GCF of 40 and 24 = 8

Solve the multistep inequality.
4x + 3 < 5x − 6

Answers

Answer:

x > 9

Step-by-step explanation:

Isolate the variable, x. Treat the < as an equal sign, what you do to one side, you do to the other.

First, subtract 5x and 3 from both sides of the inequality:

4x (-5x) + 3 (-3) < 5x (-5x) - 6 (-3)

4x - 5x < -6 - 3

-x < -9

Isolate the variable, x. Divide -1 from both sides. Note that when you divide or multiply by a negative number, you must flip the sign:

(-x)/-1 < (-9)/-1

x < -9/-1

x > 9

x > 9 is your answer.

Answer:

x > 9

Step-by-step explanation:

4x + 3 < 5x − 6

-x < -9

x > 9
