Answer:
The answer is 108mi
Step-by-step explanation:
to solve this problem, we need to write a ratio.
[tex]\frac{468mi}{13hrs}[/tex]
to solve for 3 hours, we need to figure out how many miles the bird can fly in 1 hour. to do that, we need to divide the numerator and denominator by 13.
[tex]\frac{36mi}{1hr}[/tex]
now we have a unit rate that represents distance covered per hour.
to solve for 3, we need to multiply the numerator and denominator by 3.
[tex]\frac{108mi}{3hrs}[/tex]
the question is asking for miles. therefore, the bird can fly 108mi in 3 hrs.
hope this helps!
Answer:
108 miles
Step-by-step explanation:
For this problem you can create a proportion:
[tex]\frac{468 miles}{13 hours}[/tex]
To find how many miles it flies in 3 hours, we need to find the unit fraction. Do this by making the denominator (bottom number) 1:
here, we must divide by 13:
[tex]\frac{468 miles}{13 hours}[/tex]÷[tex]\frac{13}{13}[/tex]= [tex]\frac{36 miles}{1 hour}[/tex]
Each hour, they fly 36 miles.
To find how many miles they fly in 3 hours, make a proportion:
[tex]\frac{36 miles}{1 hour}[/tex]=[tex]\frac{x miles}{3 hours}[/tex]
Then, solve:
use cross multiplication:
36·3=108
x·1=x
108=x
Which of the following is a solution of (x - 5)(x + 7) = 3x + 21
0
45
8
5
[tex](x - 5)(x + 7) = 3 x + 21[/tex]
[tex](x - 5)(x + 7) = 3(x + 7)[/tex]
[tex](x - 5)(x + 7) - 3(x + 7) = 0 \\ [/tex]
[tex](x + 7)(x - 5 - 3) = 0[/tex]
[tex](x + 7)(x - 8) = 0[/tex]
[tex]x + 7 = 0 \\ x = - 7[/tex]
Or
[tex]x - 8 = 0 \\ x = 8[/tex]
Solving a linear equation: Your hourly wage is $9.75 per hour plus
$0.80 for each unit you produce. How many units
must you produce in 1 hour so that your hourly wage
is $19.35?
Answer:
You must produce 12 units
Step-by-step explanation:
19.35 - 9.75=9.60
9.6/0.8=12
Answer:
the answer is 12 units
Step-by-step explanation:
u get 9.75 an hour and 0.80 for every unit so subtract 9.75 from 19.35 and u get 9.60 now divide that by 0.80 and u get 12 units

Logan has two aquariums. One aquarium contains 1.3 cubic feet of water and the other contains 1.9 cubic feet of water. The water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium. Write an equation with a variable on both sides to represent the situation. Then find the weight of 1 cubic foot of water.
Answer:
62.4
Step-by-step explanation:
1. 1.3x+37.44=1.9x
2. 1.3x+37.44-1.3x=1.9x-1.3x
0.6x=37.44
3. x=37.44/0.6=62.4
The weight of 1 cubic foot of water is 62.4 lb.
Representing Equation with variable on both sides
Let 'x' pounds be the weight of 1 cubic foot of water.
We know one aquarium contains 1.3 cubic feet of water. So, the weight of 1.3 cubic feet of water = 1.3x
The other aquarium contains 1.9 cubic feet of water. So, the weight of 1.9 cubic feet of water = 1.9x
It is given in the question that the water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium.
The equation would be
1.9x = 1.3x + 37.44
The above equation quality the condition of variable on both sides.
To find out the weight of 1 cubic foot of water, we will solve the above equation to find the value of x.
1.9x = 1.3x + 37.44
1.9x - 1.3x = 37.44
0.6x = 37.44
x = 37.44/0.6
x = 62.4
So, the weight of 1 cubic foot of water is 62.4 lb.

You are buying cupcakes for a school party. They are in a package of 6 for $8.50. You have budgeted no more than $40 to spend. If cost of the cupcakes is a function of the number of packages purchased, what is the largest element of the domain in this situation?
Answer: Largest element in the domain is 4
The largest number of packages you can buy is 4
======================================================
Explanation:
1 package costs 8.50*1 = 8.50 dollars
2 packages cost 8.50*2 = 17 dollars
3 packages cost 8.50*3 = 25.50 dollars
and so on. In general
x packages cost 8.50*x = 8.50x dollars
where x is a place holder for a positive whole number (1,2,3,...)
The total amount spent is 8.50x and the budget is $40
This means,
[tex]8.50x \le 40\\\\x \le \frac{40}{8.50}\\\\x \le 4.70588\\\\x \le 4\\\\[/tex]
We round down regardless of how close we are to 5.
If x = 4, then 8.50*x = 8.50*4 = 34
While if x = 5, then 8.50*x = 8.50*5 = 42.5
So we see we go over budget if we buy x = 5 packages.
This makes x = 4 the largest in the domain.
Recall the domain is the set of allowed x inputs. In this case, x is a positive whole number (since we can't buy half a package for instance).
