Mike is on vacation and decides to rent a bike for part of the week. The rental cost is represented by the function c ( d ) = 25 + 20 d c(d)=25+20d , where d is the number of days of use and c ( d ) c(d) is the total cost for d days of use. How much does the bike cost Mike if he uses it for 4 days? $120

Answers

Answer:

Total cost = $105

Step-by-step explanation:

The rental cost is represented by the function c(d)=25 + 20 d.

We need to find the cost of the bike if he uses the bike for 4 days.

Put d = 4 in the given expression.

c(4)=25 + 20 (4)

=25+80

=$105

So, the cost of the bike for 4 days is $105.

Please help

WINNER GETS BRAINLIEST!!!!!!

Answers

Answer:

1.48 m

Step-by-step explanation:

In a class of 32 students

the mean height of the 14 boys is 1.56 meters.

the mean height of all 32 students is 1.515 meters.

Total number of students = 32

Mean height of all students = 1.515

We can obtain the sum of all student's height :

Number if students * mean height

= 32 * 1.515

= 48.48

Number of boys = 14

Mean height of boys = 1.56m

We can obtain the sum of all boys height :

Number if students * mean height

= 14 * 1.56

= 21.84

Number of girls :

All students - Number of boys

32 - 14 = 18

Sum of girls height :

48.48 - 21.84 = 26.64

Mean height of girls :

Sum of girls height / Number of girls

26.64 / 18

= 1.48 m

A field is in the shape of a trapezium.
Not to scale
210 m
190m
250m
The field produces 7200 kilograms of barley per hectare.
One hectare is 10000 m²,
Work out how many kilograms of barley the field produces.

Answers

Answer:

36,000 kg

Step-by-step explanation:

✔️First, find the area of the trapezium field:

Area of trapezium = ½(a + b)*h

Where,

a = 210 m

b = 190 m

h = 250 m

Area of trapezium = ½(210 + 190)*250

= ½(400)*250

= 200*250

= 50,000 m²

✔️Find the kg of barley that 50,000 m² field will produce:

10,000 m² (1 ha) produces 7,200 kg

Therefore,

50,000 m² will produce:

(50,000*7,200)/10,000

= 5*7,200

= 36,000 kg of barley

If angle 1 = 55°, what is angle 5?
A. 55°
B. 40°
C. 35°
D. 25°

thanks ;)

Answers

It’s C because 90-55
It’s C i believe
Angle 3 and 6 both equal 90 degrees. angle 1 is collinear with 6 and 5. Those three angles (1,6, and 5) add up to 180 degrees. If you subtract your angle 6(90) from 180 , you get 90 , then u subtract ur angle one(55) from 90 and get 35 degrees. I hope this makes sense, it’s harder to explain online

Yes; there is only one domain value for each range value.

Answers

Answer:

The relation is a function.

To analyze if the relationship shown is a function, you must observe that each value of the domain has a single value of the range assigned. For the given points {(-5, 6), (-2, 3), (3, 2), (6, 4)} this requirement is satisfied. Therefore, the relationship is a function.

Step-by-step explanation:

Since there is one value of  y  for every value of  x  in  ( − 5 , 6 ) , ( − 2 , 3 ), ( 3 , 2 ), ( 6 , 4 ) , this relation is a function.
