Answer:
1.8 quartz of 80% solution and
0.9 quarts of 20% solution.
Step-by-step explanation:
Given that:
Total alcohol solution to be made = 2.7 quarts of 60% solution
Alcohol concentration in first solution= 80%
Alcohol concentration in second solution = 20%
To find:
How much of each solution must Jim use?
Solution:
Let amount of first solution to be used = [tex]x[/tex] quartz
Total amount is given as = 2.7 quarts
So, amount of second solution to be used = (2.7 - [tex]x[/tex]) quartz
As per question statement, we can write the following equation:
[tex]80\%\ of\ x +20\%\ of\ (2.7-x) = 60\%\ of\ 2.7\\\Rightarrow \dfrac{80}{100} x +\dfrac{20}{100} (2.7-x) = \dfrac{60}{100}\times 2.7\\\Rightarrow 4x+2.7-x =3\times 2.7\\\Rightarrow 3x=2\times 2.7\\\Rightarrow \bold{x =1.8\ quartz}[/tex]
First solution, 80% solution to be used = 1.8 quartz
Second solution, 20% solution to be used = 2.7 - 1.8 = 0.9 quartz

Answer: umm jus look up what a histogram is
Step-by-step explanation:
find x and m of angle wyl
Answer:
Step-by-step explanation:
x is clearly 42° because WU is an angle bisector of YWZ (which is 84, and bisecting means half of 84, that is 42)
now, for m of WYL
notice, YLW = 90°
also, UWL = 42°
name the intersection point of YL and WU as O in your mind
Apply angle sum property of a triangle for triangle WOL
angle WOL + angle UWL + angle YLW = 180
angle WOL + 90 + 42 = 180
angle WOL = 180 - 132
angle WOL = 48
now focus on line LOY
since LOY is a line, the angles a line intersecting it forms a linear pair, i.e
angle WOL + angle YOW = 180
48 + YOW = 180
angle YOW = 132
Now, apply angle sum property for triangle YOW
angle YOW + angle YWO (x) + angle WYO (or WYL) = 180
132 + 42 + WYO (or WYL) = 180
WYO (or WYL) = 6°

Which graph represents a linear function?
A coordinate plane is shown with a line passing through the y-axis at 7.5 and the x-axis at 12
A coordinate plane is shown with a line that starts to the left of the y-axis, passing through -1 comma 10, then curving right to pass through the y-axis 7, then curving down to pass through the x-axis at 2
A coordinate plane is shown with a parabola opening downward in an upside-down U shape. The base of the parabola sits at the origin and continues downward on both sides of the y-axis
A coordinate plane is shown. A wavy line begins along the x-axis and moves in intervals downward and back up, dipping down to y equals negative 1 and up to y equals 1.
Answer:
First Graph Description
Step-by-step explanation:
A linear function shows as a straight line.
The first graph description describes a straight line.
The second, third, and fourth graph description says that either the line is curved, or that it is a parabola. A parabola is not linear.
A coordinate plane is shown with a line that starts to the left of the y-axis, passing through -1 comma 10, then curving right to pass through the y-axis 7, then curving down to pass through the x-axis at 2

The wolf population of a park was 200 in the year 2000. It increased by 20% from 2000 to 2005. It then increased by 15% from 2005 to 2010. What was the wolf population in the park in 2010?
Answer:
Population 2010= 276
Step-by-step explanation:
Giving the following information:
Population 2000= 200
It increased by 20% from 2000 to 2005.
It then increased by 15% from 2005 to 2010.
First, we need to calculate the population in 2005:
Population 2005= 200*1.2
Population 2005= 240
Now, for 2010:
Population 2010= 240*1.15
Population 2010= 276
May someone please help me?
Answer:
x=8°
y=29°
Step-by-step explanation:
vertically opposite angles are equal
so 5x+9°=y+20°
therefore 5x-y=11°
Alternate angles are equal
so 4x+17°=y+20°
therefore 4x-y=3°
equation 1....... 5x-y=11°
equation 2......4x-y=3°
using elimination method x=8°
y=29°

Adalia ate lunch and wanted to leave her waitress a 15% tip. Her meal cost $8.95. How much money will the entire meal, including the tip, cost?
Answer:
Total cost = $10.2925
Approximately $10.30
Step-by-step explanation:
Cost of meal = $8.95
Tip = 15% of $8.95
= 0.15 × 8.95
= $1.3425
How much money will the entire meal, including the tip, cost?
Total cost of the meal = Cost of meal + amount of tip
= $8.95 + $1.3425
= 10.2925
Total cost = $10.2925
Approximately $10.30

A surveyor is studying a map of the community and is using vectors to determine the distance between two schools. On the map, the surveyor determined that school A is at (7, 12), and school B is at (–21, –13). The scale of the map is 1 unit = 100 meters.
Which vector represents the path from school A to school B, and what is the actual distance between them?
a) components: LeftAngleBracket 28, 25 RightAngleBracket, actual distance: about 37.54 meters
b) components: LeftAngleBracket 28, 25 RightAngleBracket, actual distance: about 3,754 meters
c) components:LeftAngleBracket negative 28, negative 25 RightAngleBracket, actual distance: about 37.54 meters
d) components:LeftAngleBracket negative 28, negative 25 RightAngleBracket, actual distance: about 3,754 meters
Answer:
C: <-28,-25>, etc.
Step-by-step explanation:
The vector from A to B is (-28, -25) and the distance between A to B is 3754 meters.
What is Coordinate Geometry?One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related. They can answer geometrical problems because it gives them geometrical aspects of algebra. In this area of geometry, a pair of ordered numbers is used to describe the location of points on a plane.
As per the given data:
Coordinates of school A = (7, 12)
Coordinates of school B = (-21, -13)
Scale of the map is 1 unit = 100 m
For vector representing the path A to B:
Final - Initial coordinates
= (-21 - 7, -13 - 12)
= (-28, -25)
Distance between A and B:
Distance formula = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
= [tex]\sqrt{(-21 - 7)^2 + (-13 - 12)^2}[/tex]
= 37.54 units {1 unit = 100 m}
= 3754 meters
Hence, the vector from A to B is (-28, -25) and the distance between A to B is 3754 meters.

The Stock Market Nadia is a stockbroker. She earns 14% commission each week. Last week, she
sold $4,500 worth of stocks. How much did she make last week in commission? If she averages that
same amount each week, how much did she make in commission in 2011?
Answer:
a). Nadia made a total of $825 last week in commission sales
b). The total amount Nadia in commission in 2011=$42,900
Step-by-step explanation: Total amount (2011)=Average weekly commission × number of weeks in 2011 where; Average weekly commission=$825 number of weeks in 2011=52 replacing; Total amount (2011)=(825×52)=42,900 . The total amount Nadia in commission in 2011=$42,900.

Find the value of x so that the ratios 8:20 and 6:x are equivalent
x=
please help asap will give brainliest
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
6:15 x = 15
Step-by-step explanation:
Simplify the ratio 8:20 by 4.
Get 2:5
SImplify 6:x by 3
GEt 2:x
To get them to be the same multiply 3 times 5. 5 from the ratio and 3 from what you divide.
Anwser 2.5=2.5
X=15
The value of x for the equivalent ratios 8/20 = 6/x is 15.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
8:20 is equivalent to 6:x
This means,
8/20 = 6/x
Solve for x.
8/20 = 6/x
x = (6 x 20)/8
x = 3 x 5
x = 15
Thus,
The value of x is 15.
