1)such A coffee maker costs $ 563 more than a blender. The total cost of two such coffee makers and 5 such blenders is $6915.How much does 1 coffee maker cost?
Answer:
$1390
Step-by-step explanation:
Given that :
Let :
Cost of blender = x
Cost of coffee maker = x +563
2(x + 563) + 5x = 6915
2x + 1126 + 5x = 6915
7x = 5789
x = 827
Cost of coffee maker = (827 + 563) = 1390

Brian has $100 in his pocket. As he is walking home 1/4th of the money falls out of his wallet. Of the remaining money, he uses $15 to buy girl scout cookies. Lastly, of the remaining money he loses 1/3rd. How much money does he have left by the time he makes it home?
Answer:
$40
Step-by-step explanation:
Brian starts at $100, then loses 1/4th of the money,
100/4 = 25,
then you subtract 25 from 100, which gives you 75
With the remaining $75, he spends $15 on girl scout cookies,
75 - 15 = 60
He then has $60 remaining, but while walking home, loses 1/3 of the total amount.
60/3 = 20,
you then subtract 20 from 60, which gives you 40
Therefore, $40 is what is remaining.

A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Answer:
The correct selling price = $10.02
The manager's likely error = $6.02
Step-by-step explanation:
Markup of 67% on all items
An item cost $6
The correct selling price = $6 + 67% of $6
= $6 + 0.67 × $6
= $6 + $4.02
= $10.02
The correct selling price = $10.02
The store manager's selling price is $4.
The manager's likely error = The correct spelling price - the manager's selling price
= $10.02 - $4
= $6.02
The manager's likely error = $6.02

lan has 30 star stickers to share. she gives 4 stickers to each of her and has 2 stickers.
how many friends does lan have.
Answer:
7
Step-by-step explanation:
this can be written as an equation, which is 4x+2= 30
X = the number of friends
30= the total of stickers
4= the stickers each friend gets
2= the amount lan gets.
Now solve the equation, first subtract 2 on both sides, which is 28
4x=28 now divide both sides by 4, which will give you 7
x= 7, that means that answer is 7
Cody is a lawyer who used to charge his clients $170 per hour. Cody recently reconsidered his rates and ultimately decided to charge $136 per hour. What was the percent of decrease in the billing rate?
Answer:
20%Step-by-step explanation:
Step one:
given data
initial charge = $170 per hour
new charge= $136 per hour.
Required
% decrease
Step two:
% decrease = initial- new /inital charge
% decrease = 170-136 /170*100
% decrease = 34 /170*100
% decrease = 0.2*100
% decrease = 20%
A plane at an altitude of 7000ft is flying in direction of an island. If they angel of depression is 21 from the plane to the island, what is the horizontal distance until the plane flies over the island?
Answer:
The horizontal distance until the plane flies over the island is 2687ft
Step-by-step explanation:
An illustrative diagram of the scenario is shown in the attachment below.
P is the position of the plane, I indicates the position of the island and G is point on the ground such that /PG/ is perpendicular to the ground.
From the diagram, the horizontal distance from the plane to the island is x.
x = /IG/
In the diagram, consider triangle PIG which is a right angle triangle.
/PI/ is the hypotenuse
/IG/ is the opposite
and /GP/ is the adjacent.
From the formula,
[tex]tan\theta = \frac{opposite}{adjacent}\\[/tex]
∴ [tex]tan\theta = \frac{/IG/}{/GP/}\\[/tex]
[tex]tan\theta = \frac{x}{/GP/}\\[/tex]
∴ [tex]x = /GP/ tan\theta[/tex]
From the diagram
/GP/ = 7000 ft and [tex]\theta = 21[/tex]
∴ [tex]x = 7000 \times tan21\\[/tex]
[tex]x = 2687.05 ft[/tex]
[tex]x[/tex] ≅ 2687 ft
Hence, the horizontal distance until the plane flies over the island is 2687ft

And a survey of 500 households 23% say that they have a dog as a pet the standard deviation is 2% determine an interval that if I need to contain the 95% of all households who has a dog as a pet
Answer:
(114.123, 115.877)
Step-by-step explanation:
Given that :
Sample size (n) = 500
Mean = 23% of 500 = 115
Standard deviation (s) = 2% of 500 = 10
α = 95%
Zcritical at 95% = 1.96
Confidence interval = Mean ± Error
Error = Zcritical * standard deviation /sqrt (n)
Error = 1.96 * 10/sqrt(500)
Error = 0.8765386
Lower boundary : 115 - 0.8765386 = 114.1234614
Upper boundary : 115 + 0.8765386 = 115.8765386
(114.123, 115.877)
