Kwame fills a bird feeder with seeds. As
birds visit the feeder, the height of the
seeds changes from 13.6 cm to 11.1 cm
over a period of 6 1/4 hours. What is the
average change in the height of the seeds
each hour?

Answers

Answer:

Step-by-step explanation:

Givens

Time = 6.25 hours

distance = 13.6 cm - 11.1 cm = 2.5 cm

Formula

rate = distance / time

Solution

rate = 2.5 / 6.25

rate = 0.4 cm/hour

In order to get to work, Lindsay takes access roads that require a toll for drivers to use. She pays $4 each day to use the access roads. She also pays $5 each day to park her car at the company lot. Assuming the toll payments are used to plot the x-coordinate and the parking lot payments are used to plot the y-coordinate, which ordered pair represents how much money Lindsay spends during a 5-day work week?

Answers

The ordered pair that represents how much she spends on a 5-day week is (20,25)

The rates are given as:

[tex]Access\ Roads = \$4[/tex]

[tex]Parking\ Lot= \$5[/tex]

From the question, x represents the access to roads, and y represents the number of days she parked her car.

So, her daily expense is:

[tex]Daily = Access\ Roads \times x + Parking\ Lot \times y[/tex]

This gives

[tex]Daily = 4\times x + 5\times y[/tex]

[tex]Daily = 4x + 5y[/tex]

For a 5-day work week, her daily expense is:

[tex]Daily = 4 \times 5 + 5 \times 5[/tex]

[tex]Daily = 20 + 25[/tex]

Express as ordered pair

[tex]Daily = (20 , 25)[/tex]

Hence, the ordered pair that represents how much she spends is (20,25)

Round to the tens place to estimate the answer.

172 x 18 =

Answers

Answer:

3400

Step-by-step explanation:

When you round to the tens place you look at the number in the ones place. If it is 4 or less then you keep the tens place the same. If it's 5 or more then you round the tens place up one. Then you make the ones digit a 0.

Since there is a 2 in the ones place in 172, you keep the tens digit the same (170).

Since there is an 8 in the ones place in 18, you round the tens digit up one (20).

Now you multiply.

170×20=3400

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.

The relation is a function.

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

1. In right triangle ABC, altitude CD is drawn to hypotenuse AB. If DB = 3
and CD = 6, find AD.

Answers

Answer:

3√2

Step-by-step explanation:

Given the following;

DB = 3

CD = 6,

Required

find AD.

using the similarity property of a triangle

DB/AD = AD/CD

3/AD = AD/6

3*6 = AD²

18 = AD²

AD = √18

AD= √9*√2

AD = 3√2

Hence the measure of AD is 3√2

(I have several, please help!!)

Answers

question 1 :- sum of all angles of a triangle is 180°

so, x + 39° + 25° + 15° = 180°

⇒x + 79° = 180°

⇒x = 101°

question 2 : draw the along with AD and make and triangle as shown in figure.

as ABCD is a parallelogram. so, angle FDE = 180° - x

and angle FED = 180° - x [ as FEA + FED = 180° ]

now from ∆DEF,

50° + 180° - x + 180° - x = 180°

⇒230° - 2x = 0

⇒x = 105°

also read : If (A + B) =(A-B) then the angle between the Ả and B.
