How many solutions does the equation 2 (p+ 7) = 4 - 8p have?
A.One solution
B.Infinitely Many Solutions
C.No Solution
Answer:
one solution p=-1
Step-by-step explanation:
The equation 2 (p+ 7) = 4 - 8p has only one solution which is -9.
What is the solution for an equation?The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of that variable would give a true mathematical statement.
We need to find the solutions does the equation 2 (p+ 7) = 4 - 8p have;
Now solving for p;
2 (p+ 7) = 4 - 8
Open the bracket;
2p+ 14 = 4 - 8
Combine the like terms;
2p = -4 - 14
2p = -18
p = -18/2 = -9
Therefore, the equation 2 (p+ 7) = 4 - 8p has only one solution which is -9.

Mr.Cunningham built himself an ice rink that is 14 and 2/5 meters long and 6 and 7/8 meters wide. What is the area of the ice rink Mr.Cunningham built?
Answer: 99 sq., meters.
Step-by-step explanation:
Given: For ice rink, Length = [tex]14\dfrac25\text{meters}=\dfrac{14\times5+2}{5}=\dfrac{72}{5}\text{meters}[/tex]
Width = [tex]6\dfrac78\text{meters}=\dfrac{8\times6+7}{8}=\dfrac{55}{8}\text{meters}[/tex]
Now, Area of ice rink = length x width
[tex]=\dfrac{72}{5}\times\dfrac{55}{8}=\dfrac{9}{1}\times\dfrac{11}{1}=99\text{ sq. meters}[/tex]
Hence, the area of the ice rink Mr.Cunningham built = 99 sq., meters.
Last year, Norman made 10 free trows per game.This year he makes 12 free trows per game.What percent increase in the number of free trows he makes this year.
Answer:
20%
Step-by-step explanation:
Given that:
Last year : number of free throws per game = 10
This year ; number of free throws per game = 12
Percentage increase in the Number of free throws he makes this year:
[(this year - last year) / last year] × 100%
[(12 - 10) / 10] * 100%
(2 / 10) * 100%
0.2 * 100%
20%
Hence, there was a 20% increase in the Number of free throws made this year.

Which shows the equation in slope-intercept form of a line with a slope of 4 and a y-intercept of -5?
Answer:
y = 4x - 5
Step-by-step explanation:
Slope-intercept form: y = mx + b
m = slope
b = y-intercept
Since 4 is the slope and -5 is the y-intercept we will substitute it for m for the slope and -5 for the b.
y = 4x + (-5)
y = 4x - 5

In a jewelry store, rings make up 5\9 of the inventory.Earrings make up 4\15 of the inventory .How many times greater is the ring inventory Than the earring inventory?
Answer:
2.083 times
Step-by-step explanation:
Given that:
Rings = 5/9 of inventory
Earrings = 4 /15 of inventory
How many times greater is the ring inventory Than the earring inventory?
To obtain the number of times ring inventory is greater than earring inventory:
Divide the fraction of inventory in ring / fraction of earring inventory
5/9 ÷ 4/15
5/9 * 15/4
= 5*15 / 9*4
= 75 / 36
= 2.083
Hence, ring inventory is 2.083 times more than earring inventory.
The bill for fixing a car was $436. The parts cost $176 and the repair center charged
$52 per hour. How many hours did it take to fix the car?
Answer:
5 hours
Step-by-step explanation:
The bill for fixing the car is $436
The parts cost $176
The repair center charged $52 per hour
Therefore the hours that it took to fix the car can be calculated as follows
= $436-$176
= $260/52
= 5 hours
Hence it will take 5 hours to fix the car
Scrieti fiecare dintre nr 24, 36 si 60 ca: a) produs de 2 factori, diferiti de 1 b) produs de 3 factori, diferiti de 1 c) produs de cat mai multi factori, diferiti de 1
Answer:
Step-by-step explanation:
1. Produse cu 2 factori
24 = 4 * 6
36 = 3 * 12
60 = 6 * 10
2. Produs de 3 factori
24 = 2 * 3 * 4
36 = 2 * 3 * 6
60 = 2 * 3 * 10
3. Cât mai mulți factori posibil
24 = 2 * 2 * 2 * 3
36 = 2 * 2 * 3 * 3
60 = 2 * 2 * 3 * 5
When a 757 passenger jet begins its descent to the Ronald Reagan National Airport in Washington, D.C., it is 3900 feet from the ground. Its angle of descent is 6 degrees
Answer:
Step-by-step explanation:
The plane's horizontal distance from the ground is 409.91 ft and the plane must fly 37310.411 ft before it descends to the ground.
Data;
Distance of the place from the ground = 3900 ftangle of depression = 6 degreeTrigonometric RatioThis is a geometric method used to find the side or angle of a right angle triangle.
The plane's ground horizontal distance from the airportTo find the plane's ground distance from the airport, we have to use trigonometric ratio
The plane distance from the ground (opposite) = 3900The angle = 6 degreeThe plane's horizontal distance from the ground (adjacent) = yFrom SOHCAHTOA
Using tangent of the angle
[tex]tan \theta = \frac{opposite}{adjacent}\\ tan 6 = \frac{3900}{y}\\ \\y = 37106.02ft[/tex]
The plane's horizontal distance from the ground is 409.91 ft.
How far must the plane fly before it descend to the groundUsing the values above,
Taking the sine angle of this since we have the value of angle and opposite.
[tex]sin\theta = \frac{opposite}{hypothenuse}\\ sin6 = \frac{3900}{x}\\ x = \frac{3900}{sin6}\\ x = 37310.411ft[/tex]
The plane must fly 37310.411 ft before it descends to the ground.
