What are the roots of the equation?
Answer:
-8 and -3
Step-by-step explanation:
[tex]x^{2} +24=-11x[/tex]
Add 11x to both sides;
[tex]x^{2} +11x+24=0\\\\(x+3)(x+8)=0[/tex]
x + 3 = 0
Subtract 3 from both sides;
x = -3
x + 8 = 0
Subtract 8 from both sides;
x = -8
Answer:
Option B ( -8 and -3 )
Step-by-step explanation:
Rewrite the equation as follows:
[tex]x^2+11x+24=0[/tex]
Now we can use two methods either the quadratic formula or the factorization method.
Lets use the factorization method.
We need two number when multiplied gives us +24 and when added up give us +11 .
Now we know 12 and 2 when multiplied give us 24 but when added give us 14 so we cant use these two numbers.
But we know 8 and 3 when multiplied give us 24 and when added give us 11 so we can use them , so rewrite the equation like,

A toy tire has a diameter of 5 cm. What is the distance, in centimeters, that the toy tire moves after 12 full rotations of the toy tire? Use 3/14 for π.
Answer:
The distance that the toy tire moves after 12 rotations is 188.4 cm
Step-by-step explanation:
The distance that a circular shape can move in n rotation is D = πdn, where
d is the diameter of the circular itemn is the number of rotation∵ A toy tire has a diameter of 5 cm
∴ d = 5 cm
∵ The toy tire moves 12 full rotations
∴ n = 12
→ To find the distance that the toy tire moves use the rule above
∵ D = (π)(5)(12)
∵ π = 3.14
∴ D = 188.4 cm
∴ The distance that the toy tire moves after 12 rotation is 188.4 cm
Solve the system of linear equations by graphing. y=2x+1. y=-x-5.
Answer:
The Solution is (-2,-3)
Step-by-step explanation:
Graphed the Equations.
Answer:
x = -2 and y = -3
Step-by-step explanation:
The format of an equation is y = mx + b where m = slope and b = y intercept The first equation will be a line with a y intercept of 1 and a slope of 2.
The second equation will be a line with a y intercept of -5 and a slope of -1.
When graphing these two lines, we will see that the two lines intersect at the point (-2,-3).
This means x = -2 and y = -3
The garden hose at Andre's house can fill a 5-gallon bucket in 2 minutes. The hose at his next-door neighbor's house can fill a 10-gallon bucket in 8 minutes. If they use both their garden hoses at the same time, and the hoses continue working at the same rate they did when filling a bucket, how long will it take to fill a 750-gallon pool?
Answer:
The time it would take them to fill 750 gallons
= 200 minutes or 3 hours 20 minutes
Step-by-step explanation:
Step 1 :
We calculate the rate at which the hoses fill for Andre and His neighbor
For Andre
The garden hose at Andre's house can fill a 5-gallon bucket in 2 minutes.
The rate is calculated as:
5 gallon/2 minutes
= 2.5 gallons/minute
For His neighbor
The hose at his next-door neighbor's house can fill a 10-gallon bucket in 8
minutes.
= 10 gallon/8 minutes
= 1.25 gallon/minute
Step 2
Hence:
If they use both their garden hoses at the same time, and the hoses continue working at the same rate, the sum of their rate =
2.5 + 1.25 = 3.75 gallons per minute.
Step 3
The time it would take them to fill 750 gallons =
750 gallons ÷ 3.75 gallons per minute
= 200 minutes
= 3 hours 20 minutes

Kevin purchased 5 hamburgers for $1.40 each and 6 sodas for $1.25 each. The tax on his order
was 8%. What was the total cost of Kevin's purchase?
A. $14.50
B. $15.66
C.$22.50
D. $14.58
Answer:
14.50
Step-by-step explanation:
hope this helps
The total cost of Kevin's purchase including tax would be $15.66
Calculating the cost of each item :
Cost of hamburgers = 5 × $1.40 = $7.00
Cost of Sodas = 6 × $1.25 = $7.50
The total cost of Kevin's purchases excluding tax is the sum of the items :
$7.00 + $7.50 = $14.50Tax paid on purchase :
8% × $14.50 = $1.16Therefore, The total amount paid including tax is ($14.50 + $1.16 = 15.66

What is the result of factoring out the GCF from the expression ( 24 + 36 ) ?
Answer:
6 is the GCF / 6(4+6)
Step-by-step explanation:
You should know your multiples up to 10, so then do some mental math and think about what number could go in each example:
Try 2: 2,4,6,8,10,12,14,16,18,20,24... except at the end we know there is most likely a greater GCF because two even numbers still remain in the parentheses.
This should be pretty fast since you should realize that three wouldnt work and same with five.

Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour. Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour. How many hours until they have the same amount of fruit left?
Answer:
72.1 hours
Step-by-step explanation:
Let the number of hours be represented as: x
Fred's Fruit Stand has 252 pounds of fruit and sells 2 7/8 pounds per hour.
Convert 2 7/8 pounds to decimal = 2.875pounds
Hence:
252 - 2.875x
Gary's grocery Store has 285 pounds of fruit and sells 3 1/3 pounds per hour.
Convert 3 1/3 pounds to decimal = 3.333 pounds
Hence:
285 - 3.333x
How many hours until they have the same amount of fruit left?
This calculated by equating both equation together
252 - 2.875x = 285 - 3.333x
Collect like terms
-2.875x + 3.333x = 285 - 252
0.458x = 33
x = 33 / 0.458
x = 72.052401747 hours
x ≈ 72.1 hours
They would have the same amount of fruit left after 72.1 hours

A cone with a radius of 6 meters has a volume of 542.87m^3. Find the slant height of the cone.
Answer:
slant height of a cone = 15.6 mStep-by-step explanation:
V = π r² h / 3
where volume V = 542.87 m³
radius r = 6 m
find height h
solution:
V = π r² h / 3
542.87 = π (6)² h
3
π (6)² h = 542.87 (3)
h = 542.87 (3)
π (6)²
h = 1628.6 / 113.1
h = 14.4 m
now solve for slant height of a cone using Pythagorean
slant height² = h² + r²
= √(14.4)² + (6)²
= √243.4
= 15.6 m
therefore, slant height of a cone = 15.6 m

24 is an outlier and it is possible that there are other outliers at the high end of the data set. There are no outliers at the low end of the data set.
Summary measures are shown below.
Min = 12
Max = 24
Lower quartile = 15
Upper quartile = 18
Median = 16
n=10
How to find outlier(s)?To find the outlier(s) in this data set, we can use the interquartile range (IQR) method. The IQR is calculated as the difference between the upper quartile (Q3) and lower quartile (Q1), which in this case is 18 - 15 = 3.
We can then use the IQR to define the limits for what is considered an outlier. Anything below Q1 - 1.5 x IQR or above Q3 + 1.5 x IQR is considered an outlier.
Using these calculations, the outlier limits for this data set are:
Lower limit = Q1 - 1.5 x IQR = 15 - 1.5 * 3 = 9.5
Upper limit = Q3 + 1.5 x IQR = 18 + 1.5 * 3 = 24.5
Thus, 24 is an outlier, and there may be further outliers at the top end of the data set. At the bottom end of the data set, there are no outliers.
Hence, the correct answer would be option (D).

Answer:
Maria states, "that means it costs $2.40 per pound of turkey." Is the correct statement
Step-by-step explanation:
Looking at the above question, we are to solve for the cost of turkey per pound.
Mariah and Clarence are planning for a dinner party. The grocery store is selling a 25- pound turkey for $60 .
Hence:
25 pounds of turkey = $60
1 pound of turkey = $x
Cross Multiply
25 × $x = 1 × $60
$x = $60/25
$x = $2.4
Hence, the cost of 1 pound of turkey is $2.4
Therefore, the person who made the correct statement is Mariah.
John bought 12 items from the concession stand. He bought cokes and nachos for his friends. Cokes cost $2.50 each and Nachos cost $3.50 each. He spent a total of $37. How many Nachos did he buy?
Answer: He bought 7 nachos.
Step-by-step explanation:
Let x= Number of cokes
y = Number of nachos
As per given , we have
x+y=12 (i)
2.50x+3.50y=37 (ii)
Multiply 2.5 on both sides of (i), we get
2.5x+2.5y= 30 (iii)
Subtract (iii) from (ii), we get
y=7 (iv)
Put value of y from (iv) in (i), we get
x+7=12
⇒ x= 12-7
⇒ x=5
Hence, he bought 5 cokes and 7 nachos.

Answer:
1.) x = 4
2.) b = -8
Step-by-step explanation:
1.) -8 - x = x - 4x (collect like terms)
-8 - x = -3x (add x on both sides)
-8 = -2x (divide by -2 on both sides)
4 = x
2.) -14 + 6b + 7 - 2b = 1 + 5b (collect like terms)
4b - 7 = 1 + 5b (subtract 4b on both sides)
-7 = 1 + b (subtract 1 on both sides)
