If (a−8)/3=(a−3)/2 , then a = ?
Answers
Answer:
[tex] \frac{(a - 8)}{3} = \frac{(a - 3)}{2} \\ 2(a - 8) = 3(a - 3) \\ 2a - 16 = 3a - 9 \\ 3a - 2a = - 7 \\ a = - 7[/tex]
Answer:
The value of a is -7. You can see the solution in the picture.

Need help with 9 and 10 thank you!!
Answers
Answer:
54° and 110°
Step-by-step explanation:
The opposite angles of a cyclic quadrilateral are supplementary, sum to 180°
(9)
19x - 26 + 7x - 2 = 180
26x - 28 = 180 ( add 28 to both sides )
26x = 208 ( divide both sides by 26 )
x = 8
Then
∠ EFG = 7x - 2 = 7(8) - 2 = 56 - 2 = 54°
(10)
21x - 33 + 14x + 3 = 180
35x - 30 = 180 ( add 30 to both sides )
35x = 210 ( divide both sides by 35 )
x = 6
Then
∠ YVW = 14x + 3 = 14(6) + 3 = 84 + 3 = 87°
The inscribed angle YVW is half the measure of its intercepted arc YW, so
arc YW = 2 × 87° = 174°, then
arc XW = 174° - 64° = 110°
Cyclic quadrilateral is drawn inside a circle. The measure of the ∠EFG is 54°. The measure of the angle made by the arc XW is 110°.
What is a Cyclic quadrilateral?A cyclic quadrilateral is a quadrilateral that is drawn inside a circle. The sum of the opposite angle of the cyclic quadrilateral is always equal to 180°.
9.) As we know that the sum of the opposite angles of a cyclic quadrilateral is supplementary, therefore, their sum is 180°. Thus, we can write for
[tex]\angle GDE + \angle EFG = 180^o\\\\19x - 26 + 7x - 2 = 180\\\\26x - 28 = 180\\\\26x = 208\\\\x = 8[/tex]
Now, substitute the value of x, in order to get the measure of the ∠EFG,
[tex]\angle EFG = 7x - 2\\\\\angle EFG = 7(8) - 2\\\\\angle EFG = 56 - 2\\\\\angle EFG = 54^o[/tex]
The measure of the ∠EFG is 54°.
10.) As we know that the sum of the opposite angles of a cyclic quadrilateral is supplementary, therefore, their sum is 180°. Thus, we can write for
[tex]\angle YXW + \angle YVW = 180^o\\\\21x - 33 + 14x + 3 = 180\\\\35x - 30 = 180\\\\35x = 210\\\\x = 6[/tex]
Now, substitute the value of x, in order to get the measure of the ∠YVW,
[tex]\angle YVW = 14x + 3\\\\\angle YVW = 14(6) + 3 \\\\\angle YVW= 84 + 3 \\\\\angle YVW = 87^o[/tex]
As we know that in the inscribed∠YVW, the ∠YVW is half the measure of its intercepted arc YW, therefore, We can write it as,
arc YW = 2 × 87° = 174°, and
arc XW = 174° - 64° = 110°
The measure of the angle made by the arc XW is 110°.

(need help ASAP) What is the probability of choosing a red jack or black king if you draw one card from a regular deck of 52 cards?
Answers
Answer:
1/13
Step-by-step explanation:
Since there are 4 suits (Clubs, Spades, Diamonds, Hearts) in total, with 2 of them being black and 2 being white, that means that each subset has 26 cards. Of these, 2 of them are either kings or jacks, depending on which subset you look at. There are 2 black kings and 2 red jacks in a regular deck of cards. The probability starts as 4/52, which is simplified to 2/26 and is finalized as 1/13. Convert to a percentage if necessary.
Lincoln technical college has 156 students they expect 700 guest for a special speaker the custodian has set up 1500 chairs how many more chairs are needed if everyone is do you have a seat
Answers
Answer: 56 seats
Step-by-step explanation:
Question should say 856 students not 156 students.
If there are 856 students and 700 guests, the total number of people coming for the event is:
= 856 + 700
= 1,556 people
There are 1,500 seats so the extra seats needed are:
=Number of people coming - Seats available
= 1,556 - 1,500
= 56 seats
If the question is indeed 156 students then there is no need for extra seats as the total number of people coming would be: 156 + 700 = 856. Seats would be surplus.

Step-by-step explanation:
The volume can be found by adding the volumes of a cylinder (the upper part of the figure) and a cone (the lower part of the figure).
Volume of Cylinder: [tex]V=\pi r^2 h=\pi(3^2)(3)=27\pi\approx 84.823 \text{ cubic feet}[/tex]
Volume of Cone: The height of the cone is 3 feet (the whole figure is 6 feet tall and the cylinder uses up 3 feet of that -- 6 - 3 = 3).
[tex]V=\frac{1}{3}\pi r^2 h=\frac{1}{3}\pi(3^2)(3)=9\pi\approx 28.274[/tex]
The total volume is 84.823 + 28.274, about 113.1 cubic feet
Cecil measures the length and width of a playground. What is the most appropriate unit of measure for the dimensions of the playground?
Answers
Answer:
Meters
Step-by-step explanation:
Meter is the standard unit of length in SI system and is normally used to measure houses and fields, therefore it is appropriate unit of measure for the dimensions of the playground.
A meter has 100 centimeters which is fairly small unit and cannot be used for dimensions of playground.
Similarly a Kilometer has 1000 meters and is used to measure long distances from one place to other which also makes it inappropriate unit for dimension of playground.

Answer:
YZ = 13.96
m∡Z = 52°
m∡Y = 38°
Step-by-step explanation:
found YZ first by using Pythagorean Theorem:
11² + 8.6² = YZ²
YZ² = 194.56
YZ = √194.56
YZ = 13.96
Used Law of Sines to find m∡Z:
sin 90°/13.96 = sin Z/11
sin Z = 11/13.96
arcsin Z = 52°
180 - (90 + 52) = m∡Y
m∡Y = 38°
if you used 16 gallon of fuel to drive 400 miles, your mpg is 20, 25, 32, 16
Answers
Answer:
25 MPG
Step-by-step explanation:
400/16 = 25
The miles per gallon of 16 gallons of fuel to drive 400 miles will be 25. The correct option is B.
What is the average of vehicles?Average refers to the distance a vehicle travels per unit of gasoline when no other conditions are present. Additionally, it is expressed as kmpl or mpg (miles per gallon) (kilometer per litter).
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that a vehicle is running 400 miles by using 16 gallons of fuel. The average of the vehicle will be calculated as below:-
Average = Distance / Quantity of fuel
Average = 400 / 16
Average = 25 mpg
Therefore, the miles per gallon of 16 gallons of fuel to drive 400 miles will be 25. The correct option is B.
