Answer:
48 minutes
Step-by-step explanation:
2h = 110 miles
1h = 110 ÷ 2
= 55 miles
Therefore, the speed of the entire journey is 55 miles per hour.
1h = 60 minutes
55 miles = 1h
55 miles = 60 minutes
44 miles = [tex]\frac{44}{55}[/tex] × 60 minutes
= 48 minutes

What is sampling?Sampling is collecting some items in a lot randomly to predict opinions about the lot.
For example; the Selection of goods, selection of people
Sampling is a useful technique because if we do it for all samples then it will take time and cost as well.
As per the given,
The cards have different names and are put into a bag.
Since no group and same name are written on the cards thus it will be a purely unbiased situation.
Thus, it will be a random sample.
Hence "The event that was picked from the bag is unbiased thus it will be a Random sample".

Niki Brought a patio set on sale for $480 the original price was $850 what was the rate of discount
If Niki Brought a patio set on sale for $480 the original price was $850, then the rate of discount is 43.52%
Given,
The original price = $850
The selling price = $480
We know discount amount is the difference between the original price and selling price
Discount amount = Original price - Selling price
Substitute the values in the equation
Discount amount =850-480
= $370
Then the discount percentage = (Discount amount ÷Original price )×100
Substitute the values in the equation
Discount percentage= [tex](\frac{370}{850})100[/tex]
=43.52%
Hence, if Niki Brought a patio set on sale for $480 the original price was $850, then the rate of discount is 43.52%

What is the value of v?
V =
Answer:
43°
Step-by-step explanation:
The first thing you should do is make the equation. We should know that the sum of all the angles is 180. So it should look like this...
[tex]49+88+x=180[/tex]
Combine like terms:
[tex]137+x=180[/tex]
Subtract the 137 on both sides:
[tex]x= 43[/tex]
That's it the value of v is 43°.
Answer:
the answer is 43
Step-by-step explanation:
this is so simple
the first thing that u have to remember or there is a rule
the rule is : that all the three angels added up equal to 180 degrees
so that means 88+49+v=180
88+49+v=180 first combine like terms
137+v=180 now subtract both sides by 137
v= 43
ANSWER CHECK
88+49= 137
137+ 43= 180
The Akashi bridge in Japan Is about one and 4/9 times as long is the Golden Gate Bridge in San Francisco the Golden Gate bridge is 9000 feet long about how long is the Akashi-Kailua bridge?
The length of the Akashi bridge is 13000 feet.
What is a fraction?A fraction is a part of a whole.
It is expressed as a quotient, in which the numerator is divided by the denominator.
Example:
1/2, 4/5.
We have,
Golden Gate Bridge = 9000 feet
Akashi bridge = 1 and 4/9 times as long as Golden Gate Bridge
Here,
1 and 4/9 times can also be written as:
1 4/9 = 13/9 x 9000
or
1 x 9000 + 4/9 x 9000
The length of the Akashi bridge:
= 1 x 9000 + 4/9 x 9000
= 9000 + 4 x 1000
= 9000 + 4000
= 13000 feet
Thus the length of the Akashi bridge is 13000 feet.

2. Identify the property of equality that justifies the missing step to solve the given equation
Answer:
Subtraction property of equality
Step-by-step explanation:
Given the equation;
2x + (x+5) = 41
open the parenthesis;
2x+x + 5 = 41 (Associative property)
3x+5 = 41
Subtract 5 from both sides
3x + 5 = 41
3x + 5- 5 = 41 - 5 (Subtraction property of equality)
3x = 36
Divide both sides by 3;
3x/3 = 36/3
x = 12 (Division property of equality)
Hence the required property is Subtraction property of equality
