At the beginning of a snowstorm, Madeline had 11 inches of snow on her lawn. The snow then began to fall at a constant rate of 0.5 inches per hour. Assuming no snow was melting, how much snow would Madeline have on her lawn 5 hours after the snow began to fall? How much snow would Madeline have on her lawn after
t
t hours of snow falling?

Answers

Answer:

y= 11+t.05. t= hours of snow

Pauline orders wristbands from two different companies. • Company 1 sells each wristband for $2 and has free shipping. Company 2 sells each wristband for $1.25 and charges $6 for shipping per order. Write an equation to model the number of wristbands, w, for which the two companies charge the same amount.

Answers

Answer:

8 wristbands

Step-by-step explanation:

Let us assume that both of the company were ordered to deliver w wristbands.

The amount of money charged by company 1 who sells at $2 and offers free shipping is given as:

2w

The amount of money charged by company 2 who sells at $1.25 and $6 for shipping per order given as:

1.25w + 6

If both companies charge the same amount, hence:

2w = 1.25w + 6

2w - 1.25w = 6

0.75w = 6

w = 6/0.75

w = 8

The two companies charge the same amount for 8 wristbands

Min Jee wants to build a small patio. It will be 70 inches long and 49 inches wide. She can't decide whether to use brick or concrete paver stones. Each brick covers an area of 3 1/2inches by 7 1/2 inches and costs $0.59. Each paver covers an area 8.4 inches by 8.4 inches and costs $1.88. Which would be less expensive to use, and by how much?

Answers

Step-by-step explanation:

firstly, let us solve for the area of the patio, from the information given the patio we have a rectangular orientation.

Area of patio

length=70in

width=49in

Area=70x49

Area=3430in^2

Area of brick

length=7.5in

width=3.5in

Area=7.5x3.5

Area=26.25in^2

Amount of brick needed =3430/26.25

Amount of brick needed =130.66

The Total cost of brick=130.66x0.59

The Total cost of brick=$77.09

Area of paver

length=8.4in

width=8.4in

Area=8.4x8.4

Area=70.56in^2

Amount of brick needed =3430/70.56

Amount of brick needed =48.61

The Total cost of brick=48.61x1.88

The Total cost of brick=$91.38

Brick would be less expensive by =91.38-77.09= $14.29

Three friends, Cleopatra, Dalila and Ebony go shopping.
The money they each have is in the ratio
Cleopatra : Dalila : Ebony = 5:7:8.
Cleopatra has $17.
(a) How many dollars do they have in total?
(b) Dalila spends $12 on a hat.
How many dollars does she have left?
(CIE Paper 1, Nov 2005)​

Answers

Solution (a) :

Total number of parts = 5 + 7 + 8 = 20

Let the sum of the money with them be = x

Cleopatra has =

= 5/20 of x = $17

= 5/20x = 17

= 1/4x = 17

= 1x = 17 × 4 ( transposing ÷4 from LHS to RHS changes ÷4 to ×4 )

= x = 68

Therefore , they have $68 in total .

Solution (b) :

Total number of parts = 5 + 7 + 8 = 20

Parts with Dalila = 7/20

Money with Dalila =

= 7/20 of 68

= 7/20 × 68/1

= 476/20

= 23.8

Dalila has $23.8 with her .

Money she spends on a hat = $12

Money left with her =

= 23.8 - 12

= 11.8

Therefore , Dalila has $11.8 left with her , after she buys a hat .

Solution to the problems in the comment box :-

Solution (1) :

Ratio of cement to sand to aggregate to water = 2:5:8:1

Total parts = 2 + 5 + 8 + 1 = 16 parts

Number of parts for aggregate = 8/16

Then the aggregate needed by Bobbie =

= 8/16 × 1.2

= 1/2 × 1.2

= 1.2 as a fraction will be 6/5

= 1/2 × 6/5

= 6/10

6/10 as a decimal = 0.6

Therefore , Bobbie needs 0.6 cube of meter .

Solution (a) :

Cement : sand : aggregate : water = 2:5:8:1

Total parts = 16

Number of parts for cement = 5/16

Let the quantity of concrete be = x

Then ,

Cement =

= 5/16 of x

= 5/16x = 0.25 meter cube

= x = 0.25 × 16/5

= x = 25/100 × 16/5

= x = 1/4 × 16/5

= x = 16/20

= x = 4/5

4/5 as decimal = 80/100 = 0.08

Cement needed by Eddie = 0.08 cubic meter .

Quantity of water Eddie will need =

= 1/16 × 0.08

= 1/16 × 80/100

= 1/16 × 8/10

= 8/60

= 0.13

Water needed by Eddie = 0.13 cubic meter .

Quantity of aggregate needed by Eddie =

= 8/16 × 80/100

= 1/2 × 8/10

= 8/20

= 40/100

= 0.04

Aggregate needed by Eddie = 0.04 cubic meter .

Quantity of sand Eddie will need =

= 5/16 × 80/100

= 5/16 × 8/10

= 40/160

= 0.25

Quantity of sand needed by Eddie = 0.25 cubic meter .

Therefore , Eddie will need 0.25 cubic meter of sand , 0.04 cubic meter of aggregate ,0.13 cubic meter of water along with 0.25 cubic meter of cement to make concrete .

Solution (b) :

When water and aggregate has been added the quantity of concrete =

= 0.13 + 0.04

= 0.07

Therefore , when water and aggregate has been added the quantity of concrete will be 0.07 cubic meter .

Tamara bought yarn for $39 and 2 pairs of knitting needles. Her total cost for the yarn and knitting needles was $69. Tamara writes an equation that represents the cost of each pair of knitting needles. If k represents the cost of each pair of knitting needles, which statements about verifying the value of k are true? Check all that apply.
Tamara should substitute k = 30 into the equation 39 + 2 k = 69.
After she substitutes the correct value for k into the equation, Tamara should find that the left side of the equation is equal to the right side.
Tamara should substitute k = 15 into the equation 39 + 2 k = 69.
After she substitutes the correct value for k into the equation, Tamara should find that the left side of the equation is not equal to the right side.
To verify the solution to the equation, Tamara multiplies the solution by 2 and then adds it to 39. Then, she checks that it is equal to 69.
To verify the solution to the equation, Tamara adds the solution to 2 and then adds it to 69. Then, she checks that it is equal to 39.

Find the equation of the line.

Y=__x + __

Answers

Answer:

y = 3x + 3

Step-by-step explanation:

Using slope intercept form: y = mx + b

where m is the slope(rise over run/change in y over change in x), and b is the y intercept(point where x is 0). We can derive the equation by simply using our mathmatical principles of slope and y intercept. Because our y intercept is where x is 0. Our y intercept is 3 since x is 0 when y is 3 because it touches the axis. Since y is 6 when x is one.

y = mx + b

6 = m(1) + 3

-3 -3

_________

3 = m

_________

m = 3

_________

An m of 3 means that you rise 3 every 1 run or 3y every 1x.

Therefore, our equation in slope intercept is:

y = 3x + 3

  coordinates  = (a,4)

Solution:

  From the given coordinates;

       x = a

       y = 4

       4x + 2y  = 36

 Substitute for the values and find "a"

    4a + 2(4)  = 36

Three months later it is 51 809. How many units of gas has he used? c) Electricity costs 12 pence per unit. Gas costs 8.6 pence per unit. Work out the total cost of Mr Patel's gas and electricity for these three months. Give your answer in pounds.

Answers

Answer: 172.65 pound

Step-by-step explanation:

a. What is the reading on his meter at the end of these three months?

January's electricity meter reading = 36,517.

Electricity used for next three months = 1 084 units

Meter reading at the end of the three months will be:

= 36517 + 1084

= 37601

b. In Janurary Mr Patel'a gas meter reading is 51 314. Three months later it is 51 809. How many units of gas has he used?

This will be:

= 51,809 - 51,314

= 495 units

c. Electricity costs 12 pence per unit. Gas costs 8.6 pence per unit. Work out the total cost of Mr Patel's gas and electricity for these three months.

Electricity used for next three months = 1 084 units

Gas used for next three months

= 495 units

Cost = (1084 × 12pence) + (495 × 8.6 pence)

= 13008 pence + 4257 pence

= 17265 pence = 172.65 pound

Kevin and monica lead visitor tours at a museum. Last month, both kevin and monica led the same number of vistors. Kevin lead 150 adults, plus 6 student groups. Monica led 134 adults, plus 8 student groups. If each student group had the same number of students, which equation could be used to determine the number of students in each group?

Answers

Answer:

Number of students in each group = 8

Step-by-step explanation:

kevin and monica led the same number of vistors.

Let x = number of students in each group

Kevin lead 150 adults, plus 6 student groups.

150 + 6x

Monica led 134 adults, plus 8 student groups.

134 + 8x

Equate both equations

150 + 6x = 134 + 8x

Collect like terms

150 - 134 = 8x - 6x

16 = 2x

Divide both sides by 2

x = 16 / 2

= 8

x = 8

Number of students in each group = 8
