If steak costs $12.55 per pound, what will be the total cost of 0.6 pounds of steak?\

Answers

Answer:

Solve for X; whereas lb=pound, $=cost

1lb = $12.55

0.6lb = $X; therefore 6/10 lb = $X

Rewrite:

$12.55/1 lb = $X/6/10 lb; therefore $12.55/1 lb = 10/6(X); 10X=$12.55(6); 10X=$75.30; X=$75.30/10

X=$7.53 for .6 lbs.

The population of Medford High School is
800 students and the population of
Westville High School is 1240 students.
The population of Medford High is
increasing at a rate of 30 students per
year, while the population of Westville
High is decreasing by 25 students per
year. In about how many years will the
population of the two schools be the
same?

Answers

Answer:

in 8 years each school will have about 1,040 students

Step-by-step explanation:

let 'x' = years

y = 30x + 800

y = -25x + 1240

30x + 800 = -25x + 1240

55x = 440

x = 8

answer this qustion plz and if get right i might give you brainlist

Answers

Answer:

A

Step-by-step explanation:

SO right off the bat it cannot be c, for they do definatly change.

Next, lets find out how much they change by.

The median would now be 120. Since adding 1 more number would make it just 120. Instead of it being 120+130/2.

This is a decrease of 5. Because we can just subtract normal number by new number: 125-120=5.

Now, the mean is already 500/4. This equals 125.

So lets add 0 to that. So now we must divide it by 1 more number, 4+1=5.

That is 500/5. This equals 100.

This is a decrease of 25. Because we can again subtrasct the normal number by the new number: 125-100=25

That is 5x more of a decrease than the mean.

SO it must be A, since the mean decreased more than the median.

There are 20 sweets in a bag.
Seven of them are strawberry.
A sweet is taken at random from the bag.
What is the probability that the sweet taken is not strawberry?

Answers

7 of the sweets in the bag are strawberry. Since there are 20 sweets total in the bag, 20 - 7 = 13 sweets in the bag must be non-strawberry.

The probability that a sweet taken at random from the bag is not strawberry would thus be 13/20.

Can someone please answer this please for god's sake

Answers

Answer:

x = 36 degrees

y = 48 degrees

Step-by-step explanation:

The two given triangles are congruent

Hence, we can say that the interior angles are equal

We shall use the angle markings on each of the triangles

Using the markings, we can see that y is 48 degrees

Now, let us find the last angle measure of the first triangle

Mathematically, the sum of angles in a triangle is 180

Thus;

108 + 48 + A = 180

A = 180 - 48 - 108

A = 180 - 156 = 24

Now, the measure 2x-y is equal to this;

Hence;

2x -y = 24

2x = 24 + y

we have that y = 48

2x = 24 + 48

2x = 72

x = 72/2

x = 36 degrees

Each event uses a standard deck of playing cards. The cards are chosen at random and put back after each draw.
Match each event with its theoretical probability.
You choose a red card.
You choose the queen of hearts.
You choose a club.
You choose a 5, 6, or 7. 11 :: 3 13 52


PUT THEM IN ORDER! AND I'LL GIVE YOU "⭐"​

Answers

Answer:

See below

Step-by-step explanation:

The probability of choosing a red card is 1/2. Half of the cards are hearts/diamonds and half of the cards are clubs/spades.

The probability of choosing the queen of hearts is 1/52. There is one queen of hearts in a 52 card deck.

The probability of choosing a club is 1/4. 1/4 of the cards are clubs, 1/4 are spades, 1/4 are diamonds, 1/4 are hearts.

The probability of choosing a 5, 6, or 7 is 3/13. There is a 5, 6, 7 in all 4 sets, clubs, spades, hearts, and diamonds. So there are 12 total cards that either read 5, 6, or 7 out of the 52 total cards. 12/52 simplifies to 3/13.
