Answer 1

Answer:

1. 2/5, 2. -1. 3. 5/2, 4. 1, 5. 1/5, 6. -4/3, 7. 1/3, 8. -1/10

Step-by-step explanation:

1-3: the formula for slope is (y2 - y1)/(x2 - x1) for points (x1, y1) and (x2, y2)

1. we have points (-2, -1) and (3,1) ,plug these into the formula to get (1-(-1))/(3-(-2)) = (1+1)/(3+2) = 2/5 so the slope is 2/5

2. we have points (-3, 2) and (2, -3): (-3-2)/(2-(-3)) = -5/5 = -1

3. (-1, -2) (1,3): (3-(-2))/(1-(-1)) = 5/2

4-6: you can use the same formula

4: (1,0) (3,2): (2-0)/(3-1) = 2/2 = 1

5. (8,0) ( 13, 1) (1-0)/(13-8) = 1/5

6. (2, -1) ( 5, -5) (-5+1)/(5-2) = -4/3

7-8: slope= rise/run

7. rise=8, run=24, 8/24=1/3

8. rise=-100, run=1000, slope= -100/1000 = -1/10

The Jurassic zoo charges $6 for each adult admission and $4 for each child. The total bill for 244 people is $1078. He many adults and how many children went to the zoo

Answers

Answer:

51 adults and 193 children

Step-by-step explanation:

Number of children = c

Cost for c children = c*4 = 4c

Number of adults = a

Cost for a adults = 6a

Total people = 244

a + c = 244 ---------------(I)

a = 244 - c ----------(II)

Cost for 244 people = $ 1078

6a + 4c = 1078 -------------(III)

Substitute a = 244 - c in equation (III)

6*(244 - c) + 4c = 1078

1464 - 6c + 4c = 1078

1464 - 2c = 1078

-2c = 1078 - 1464

-2c = -386

c = -386/-2

c = 193

a = 244 - 193

a = 51

A fruit basket contains oranges and grapefruits. 1/3 of oranges and 1/4 of the grapefruits were spoiled. You threw away 4 oranges and 7 grapefruits. How many pieces of fruit were in the basket before you threw out the spoiled ones?

A rectangle of dimensions 60 units x 40 units is drawn on grid paper with vertices in
the nodes of the grid. A cell of the grid is 1 unit * 1 unit. A diagonal of the rectangle is
drawn. How many cells have been cut into two (not necessarily equal) parts?

Answers

The number of cells which have been cut into two parts is approximately ; 72 units

According to the question;

The rectangle has dimensions 60 units x 40 units.

Provided a cell of the grid is 1 unit * 1 unit.

When a diagonal of the rectangle is drawn;

The number of cells which have been cut into 2 pieces is the length of the diagonal of the rectangle.

Diagonal, D² = 60² + 40²

D² = 3600 + 1600

D² = 5,200

D = √5200

D = 72.11 units

Answers

Answer:

Step-by-step explanation:

helicopter=65m

tap of the cliff=

the boy=350m

210=

that makes the answer 205

Answer:

205 meters

Step-by-step explanation:

The cliff is 350m, and the rescue helicopter is 65m above the top of the cliff.

This means that the helicopter is 415 meters above the bottom of the cliff.

The boy is 210m above the bottom of the cliff.

So, you have to subtract 210 from 415 to get 205.

Therefore, you have to lower the rescue 205m to reach the boy.

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given that n represents the number of cards that students sold last year. Also, it is given that each card is sold for $20. Therefore, the given pairs can be matched as shown below.

1.) Revenue from last year

Revenue = Number of tickets sold last year × Cost of each ticket

= n × $20

= 20n

2.) Number of cards sold this year if students sell 200 more cards than last year

Number of cards sold this year = Number of tickets sold last year + 200

= n + 200

3.) Revenue this year if students sell 200 more cards than last year

Revenue this year = Number of cards sold this year × Cost of each ticket

= (n + 200) × 20

= 20(n+200)
