Not liking rock mostly doesn't effect not liking just rap, since half like both rock and rap.
Though, there are 2 more people that like just rock compared to just rap, so you are more likely to like just rock.
Additionally, if you don't like rock, there is a 31.4 % that you don't like rap as well, since 17 people like neither.
3×-y=5,2×+y=5 pleaseplease
Answer:
x = 2
y = 1
Step-by-step explanation:
3x - y = 5..............(1)× 1
2x + y = 5...….......(2)× 1
3x - y = 5..............(3)
2x + y = 5.............(4)
Cancel y
3x + 2x = 5 + 5
5x = 10
Divide both sides by 5
x = 2
Substitute for the value of y
3x - y = 5
3(2) - y = 5
6 - y = 5
6 - 5 = y
1 = y
y = 1
There are two consecutive even numbers such
that twice the first is 46 more than the second.
Form an equation and solve to find the two
numbers.
Step-by-step explanation:
Let the numbers be x and y
2 consecutive even nos.
therefore y = x+2
twice of the first (2x) is 46 more than y
2x = y+46
Solving both the equations
x - y + 2 = 0
(-)2x - y - 46 = 0
____________
-x + 0 + 48 = 0
____________
x = 48
y = x+2
= 48 +2
= 50
Therefore the 2 nos. are 48 and 50

An experiment consists on rolling a fair number cube. There are 6 possible outcomes: 1, 2, 3, 4, 5, and 6. Find the probability P(rolling a 7).
Answer:
0
Step-by-step explanation:
The only possible outcomes on the die are 1,2,3,4,5,6.
Since 7 is not in the possible outcome list, It is impossible to obtain a 7 on this 6-sided die.
If the question had asked for the probability of other values, it would have been 1/6, because you can get each number at least once every 6 rolls. This, however varies in terms of experimental probability

In a survey, the ratio of the number of people who preferred tea to those who preferred coffee was 9:5
36 more people preferred tea to coffee.
How many people were in the survey?
Answer:
45 people prefered coffee, 81 people prefered tea. A total of 126 people were surveyed.
Step-by-step explanation:
Let t be the people who prefer tea, and let c be the people who prefer coffee.
The ratio between tea and coffee is 9:5, thus we have t/c=9/5. Cross products give us 5t=9c.
Also, we have 36 more people prefer tea than coffee, so we have c+36=t
Thus we have: 5(c+36)=9c
5c+180=9c
180=4c
c=45
c+36=t
45+36=81

At work Bret must check and record the internal temperature of the freezer on an hourly basis when working properly the temperature should remain constant over time.What word describes the slope of a line showing the temperature of the freezer as a function of time in hours when the freezer is working properly
Answer:
The slope of the line will be ZERO.
From the question given above, we are told that when the freezer is working perfectly that the temperature will remain constant over time. This means that if the graph of temperature and time is drawn, the slope of the graph will be constant from one point of the graph to the other, which means that the values will cancel each other out and will be zero.
a parking garage charges $2.50 base free plus an hourly rate of $4.00. If you hve most $12.50 how many parking you can
Answer: 2.5 hours or 2 hr and 30 min
Step-by-step explanation:
We can set up an equation to find how many hours you can park.
2.5+4x=12.5
The 2.5 comes from the base fee. The 4x is the hourly rate, where x is hours. The 12.5 is the total amount of money you have.
Since we have our equation, we can solve for x.
4x=10
x=2.5
You can park for 2.5 hours, or 2 hours and 30 min.

Let PQR be a triangle such that angle P = angle Q + angle R. Among all three exterior angles of triangle PQR, what is the smallest exterior angle, in degrees?
Answer:
The smaller exterior angle is the exterior angle in the vertex P, and it measures 90°
Step-by-step explanation:
The sum of the internal angles of a triangle needs to be 180 degrees, so we have two equations:
[tex]mP = mQ + mR[/tex]
[tex]mP + mQ + mR = 180\°[/tex]
Substituting [tex]mQ + mR[/tex] by [tex]mP[/tex] in the second equation, we have:
[tex]mP + mP = 180\°[/tex]
[tex]mP = 90\°[/tex]
The other two angles need to be lesser than mP, and the exterior angle is the supplement of the internal angle, so the bigger the internal angle, the smaller the exterior angle.
So if the bigger internal angle in this triangle is mP, the smaller exterior angle is also the angle in the vertex P:
[tex]exteriorP = 180\° - mP[/tex]
[tex]exteriorP = 90\°[/tex]

Find the area. Use Pi = 3.14 a. 15.1976 cm2 c. 13.816 cm2 b. 6.908 cm2 d. 60.7904 cm2
Answer:
A.
Step-by-step explanation:
Diameter = 4.4 cm
Radius = 2.2 cm
Now
Area of the circle = πr²
= (3.14)(2.2)²
= (3.14)(4.84)
= 15.1976 cm²
Answer:
A.
Step-by-step explanation:
D=4.4, therefore, the Radius is equal to 2.2, half of the diameter.
The formula for Area:
A=pir^2.
A=(3.14)(2.2)^2
A=(3.14)(4.84)
A=15.1976
A=15.1976, which is identical to option A.
could any one explain this problem?
Answer:
C
Step-by-step explanation:
Δ AQP and Δ ACB are similar triangles, thus the ratios of corresponding sides are equal, that is
[tex]\frac{AQ}{AC}[/tex] = [tex]\frac{PQ}{BC}[/tex] ( note that AC = 3 + 6 = 9 ), substitute values
[tex]\frac{3}{9}[/tex] = [tex]\frac{4.5}{BC}[/tex] ( cross- multiply )
3BC = 40.5 ( divide both sides by 3 )
BC = 13,5 cm → C

The diameter of a sphere is 4 centimeters. Which represents the volume of the sphere?
32/3 cm3
8 cm3
64/3 cm3
16 cm3
Answer:
[tex]\frac{32}{3}[/tex] π cm³
Step-by-step explanation:
The volume formula for a sphere is [tex]\frac{4}{3}[/tex] × π × r³.
Since the diameter is 4 and the diameter is 2 radiuses, we get the radius as 2 centimeters.
Plugging r into our formula we get,
[tex]\frac{4}{3}[/tex] × π × 2³ =
[tex]\frac{4}{3}[/tex] × π × 2 × 2 × 2 =
[tex]\frac{4}{3}[/tex] × π × 4 × 2 =
[tex]\frac{4}{3}[/tex] × π × 8 =
[tex]\frac{32}{3}[/tex] × π =
[tex]\frac{32}{3}[/tex] π cm³
The solution is, 32/3 π cm³ is the volume of the sphere.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
we know that,
The volume formula for a sphere is 4/3× π × r³.
Since the diameter is 4 and the diameter is 2 radiuses,
we get the radius as 2 centimeters.
Plugging r into our formula we get,
4/3 × π × 2³
=4/3 × π × 2 × 2 × 2
=4/3 × π × 4 × 2
=4/3 × π × 8
=32/3 × π

What is the value of x in the equation 8x - 2y = 48, when y = 4?
O 6
07
O 14
O 48
Answer:
The answer is option 2.
Step-by-step explanation:
You have to substitute the value of y into the equation :
[tex]8x - 2y = 48[/tex]
[tex]let \: y = 4[/tex]
[tex]8x - 2(4) = 48[/tex]
[tex]8x - 8 = 48[/tex]
[tex]8x = 48 + 8[/tex]
[tex]8x = 56[/tex]
[tex]x = 56 \div 8[/tex]
[tex]x = 7[/tex]
The value of x in the equation 8x - 2y = 48 is 7.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
8x - 2y = 48
Now, for y=4 put the value of y as 4 in given equation we get
8x- 2(4)= 48
8x -8= 48
8x = 48+ 8
8x = 56
x= 56/8
x= 7
Thus, the value of x is 7.

Trapezoid A B C D is shown. Sides A B and D C are parallel. Sides A D and B C are congruent. Angle B is (3 x) degrees and angle D is (9 x) degrees. What is the value of x in trapezoid ABCD? x=15 x=20 x=45 x=60
Answer: The value of x in trapezoid ABCD is 15
Step-by-step explanation: The trapezoid as described in the question has two bases which are AB and DC and these are parallel. Also it has sides AD and BC described as congruent (that is, equal in length or measurement). These descriptions makes trapezoid ABCD an isosceles trapezoid.
One of the properties of an isosceles trapezoid is that the angles on either side of the two bases are equal. Since line AD is equal to line BC, then angle D is equal to angle C. It also implies that angle A is equal to angle B.
With that bit of information we can conclude that the angles in the trapezoid are identified as 3x, 3x, 9x and 9x.
Also the sum of angles in a quadrilateral equals 360. We can now express this as follows;
3x + 3x + 9x + 9x = 360
24x = 360
Divide both sides of the equation by 24
x = 15
Therefore, in trapezoid ABCD
x = 15
