Answer:

Mason counted 24 more birds at his feeder than Rosa counted at hers

Step-by-step explanation:

Average = Total or sum/number of items

Therefore, Total or sum = Average × number of items

For Mason,

An average of 18 birds in 20 day is equivalent to a total of

Total birds = 18 × 20

                 = 360 birds

For Rosa,

An average of 21 birds each day for 21 days is equivalent to a total of

Total birds = 21 × 16

                   = 336 birds

Difference between the total number of birds for Mason and Rosa

= 360 - 336

= 24 birds

Answer:

It would be x < 4.

Step-by-step explanation:

Your answer would be x < 4. This is because with this inequality, x would always be less than 4.

Know This:

<em>If it was less than or equal to 4 feet, it would of been x ≤ 4.</em>

Tips:

<em>Less or equal to:  x ≤ 4</em>

<em>Less than: x < 4</em>

<em>More or equal to: x ≥ 4</em>

<em>More than: x > 4</em>

At the farm, Justin picks 3 bushels of fruits. The bushels weigh 8 1/4 pounds, 6 1/2 pounds, and 6 5/8 pounds. What is the avera
blondinia [14]
ANSWER

Average \: Weight =  7 \frac{1}{8}  \: bushels


EXPLANATION

To find the average weight per bushel, we add all the three weight and divide by 3.


Average \: Weight =  \frac{8 \frac{1}{4}  + 6 \frac{1}{2} + 6 \frac{5}{8}  }{3}


We convert all the mixed numbers to improper fraction to obtain,


Average \: Weight =  \frac{ \frac{33}{4}  +  \frac{13}{2} + \frac{53}{8}  }{3}


The least common denominator for the fractions in the numerator is 8.


This implies that,

Average \: Weight =  \frac{ \frac{66 + 52 + 53}{8} }{3}

This simplifies to


Average \: Weight =  \frac{ \frac{171}{8} }{3}


This gives us,

Average \: Weight =   \frac{171}{24}



Average \: Weight =   \frac{57}{8}


Average \: Weight =  7 \frac{1}{8}

A FedEx treight truck carries three tons of packages 660 miles on 90 gallions of diesel fuel from Miami, FL. to Atlanta, GA. Fed
musickatia [10]

Ans(a):


Given that a FedEx freight truck carries three tons of packages 660 miles on 90 gallons of diesel fuel from Miami, FL to Atlanta, GA.


so that means speed of the truck is


speed = distance/time = 660/90 miles per gallon


hence slope of the equation will be


m=660/90 = 66/9= 22/3


There is no information about initial cost or any initial value so that means y-intercept b=0


plug value of m and b into y=mx+b


so we get equation y=22/3x+0


Where x is the number of gallons and y is the number of miles


Now we can easily graph this equation to get the required graph.


when x=0 then y=22/3x=22/3*0=0


so first point is (0,0)


when x=3 then y=22/3x=22/3*3=22


so second point is (3,22)


Now we join them by a line to get the graph


Ans(b):


clearly number of gallons can't be negative so domain is all positive real numbers.


Ans(c):


Origin of the graph represents that if there is no gallons of fuel used then there will be no distance traveled.

Substitute (2, 1) into x + 3y = 5 to get ✔ 2 + 3(1) = 5 . Simplify the equation to get . Substitute (2, 1) into y = –x + 3 to ge
nikdorinn [45]

Answer:

See explanation

Step-by-step explanation:

A

x + 3y = 5

(x, y) = (2,1)

x + 3y = 5

2 + 3(1) = 5

2 + 3 = 5

5 = 5

The equation is true

B.

y = –x + 3

(x, y) = (2, 1)

y = –x + 3

1 = -2 + 3

1 = 1

The equation is true
