Dustbuster cleaning services, charges $35 per
hour.

​

Answers

Answer 1

Answer:

Klean company = 20 + 25h

Dustbuster cleaning services = 35h

Step-by-step explanation:

Let

Number of hours = h

Equation to calculate the cost of cleaning your house

Klean company = 20 + 25h

Dustbuster cleaning services = 35h

Find the number of hours when the cost of cleaning house by both companies will be equal

Klean company = Dustbuster cleaning services

20 + 25h = 35h

20 = 35h - 25h

20 = 10h

h = 20/10

h = 2 hours

Number of hours = h = 2 hours

The circumference of a circle is 8.44cm.
Find the length of the diameter.
Give your answer rounded to 2 DP.​

Answers

Answer:

Diameter = 2.68cm

Step-by-step explanation:

Circumference of a circle = 2πr

Circumference of a circle = 8.44cm

π = 3.14

r = ?

Circumference of a circle = 2πr

8.44 = 2 * 3.14 * r

8.44 = 6.28r

r = 8.44/6.28

r = 1.3439490445859

Approximately

r = 1.34

Diameter = 2r

Diameter = 2 * 1.34

Diameter = 2.68cm

The ratio of the number of Baskin Robbins :Cold stone ice cream cones sold in a day is 11:9.If the number of Baskin Robbins cone sold is 44 .(a)How many cold stone cones are sold ? (b)If the number of cold stone cones on the next day is reduced to 20.what is the new ratio?

answer fast plsssssssssssssssssssssssssssssssss

Answers

Answer:

a) 36

b) 11:5

Step-by-step explanation;

a) let the number of cold stone cones be x

Since the initial ratio is 11:9

we have the ratio of the ice creams as;

11:9 = 44:x

11/9 = 44/x

11 * x = 9 * 44

x = (9 * 44)/11

x = 9 * 4 = 36

b) Now, from 36, we have a number of cold stones as 20

So the ratio now will be;

44:20

and that would be;

11:5

Among the licensed drivers in the same age group, what is the probability that a 78-year-old was involved in an accident? Use the table below.​

Answers

Answer:

C. 6.6%

Step-by-step explanation:

The probability of an event 'A' occurring, P(A) is given by the ratio of the number of times event A occurs to the some of all possible events

Mathematically, we have;

[tex]The \ probability \ of \ an \ event = \dfrac{The \ number \ of \ the \ required \ outcome}{The \ number \ of \ all \ possible \ outcomes}[/tex]

The number of drivers involved in an accident who are above 75 years = 13,321

The total number of drivers in accidents = (10,034 + 17,173+ 35,712+ 40,322 + 40,937 + 30,355 + 17,246 + 13,321) = 205,100

A 78-year-old is in the age group of 75 and older

∴ The probability that a 78-year-old licensed driver was involved in an accident = The probability that a 75 and older year-old licensed driver was involved in an accident = 13,321/205,100 ≈ 0.06495 = 6.5%

Therefore, the best option is option C. 6.6%

The area of the trapezium above is 22 cm².
What is the value of x ?

Answers

Answer:

4cm

Step-by-step explanation:

Given area= 22cm²

Height =4cm

Parallel sides = xcm and 7cm

Area of trapezium = ½( sum of parallel sides) x height

22cm² = ½(xcm+7cm)×4cm

22cm²= ½ ( x+7)cm x 4cm

opening the bracket

22cm²= 4x+28/ 2

cross multiply

44cm²=4x+28

4x=44-28

4x=16

x=4cm
