The area of a rectangular garden in square feet can be represented by z² - 10z +21. The length is z - 7 feet. You have been hired to fertilize the
garden. Recall that the area of the garden is z² - 10z +21. If z = 20 and the fertilizer costs $0.27 per square foot, how much it cost to fertilize
the garden?
Answer:
$ 59.67
Step-by-step explanation:
The area of a rectangular garden in square feet can be represented by z² - 10z +21 square feet
If z = 20
Therefore:
The area of the rectangular garden is:
20² - 10 × 20 + 21
400 - 200 + 21
= 221 square feet
The fertilizer costs $0.27 per square foot, how much it cost to fertilize
the garden?
The cost of fertilize the garden is calculated as:
1 square feet = $0.27
221 square feet = x
Cross Multiply
221 square feet × $0.27
=$ 59.67
Fill in the blanks to complete the area model to solve 6.60 divided by 15 is the same as _ x ? = _ 6.60 = _ hundredths
Answer:
[tex]15 x = 6.60[/tex]
[tex]x = 44\ hundredths[/tex]
Step-by-step explanation:
Given
[tex]\frac{6.60}{15}[/tex]
Required
Complete the model
[ ] x = 6.60
x = _ hundredths
[tex]\frac{6.60}{15}[/tex]
Equate to x
[tex]x = \frac{6.60}{15}[/tex]
Multiply both sides by 15
[tex]15 * x = \frac{6.60}{15} * 15[/tex]
[tex]15 * x = 6.60[/tex]
[tex]15 x = 6.60[/tex]
So, we have:
[ ] x = 6.60 =====> [tex]15 x = 6.60[/tex]
Recall that:
[tex]x = \frac{6.60}{15}[/tex]
[tex]x = 0.44[/tex]
This implies that:
[tex]x = 44\ hundredths[/tex]
Hence:
x = _ hundredths =====> [tex]x = 44\ hundredths[/tex]

what number is b in algebra
Answer:
I could be any number.
But it couldn't just be a 'b' it could be other letters. The letters is just a grown up way of saying a missing number. Its like saying:
10+b=11..
11-b=10..
therefore b=1
Does that make sense
It can also mean in the quadratic formula b
Step-by-step explanation:
In algebra, the variable "b" represents an unknown or variable number.
It is used to denote a quantity that can vary or take on different values. The purpose of using variables in algebraic equations is to generalize mathematical relationships and solve problems with unknown quantities. By assigning the letter "b" to a variable, we can manipulate and solve equations using algebraic operations, such as addition, subtraction, multiplication, and division.
The value of "b" can be determined through various methods, such as solving equations, simplifying expressions, or applying mathematical principles. The flexibility of variables like "b" allows us to solve a wide range of problems and analyze mathematical relationships without relying on specific numerical values.

6. Markets with elastic supply and demand curves: a) Have demand and supply curves that never intersect. B) Are very sensitive to a change in price. C) Have greater movements in quantity than prices. D) Are very sensitive to a change in quantity. E) Are only theoretical and do not exist in the real world.
Answer:
The correct statement is B (are very sensitive to change in price)
Step-by-step explanation:
Option B is correct because of the following reason -:
The degree to which a rise in price affects the quantity demanded or supplied is known as elasticity. In the case of elastic demand and supply, as the price rises, the quantity demanded falls and the quantity supplied rises more than proportionally. Inelastic price elasticity of demand and supply, on the other hand, induces a less than proportional change in quantity as prices change.
Hence , the correct option is B .

$54000. Oliver was told that for each year he stays with the company, he will be
given a salary raise of $3000. How much would Oliver make as a salary after 6 years
working for the company? What would be his salary after t years?
Answer:
After 6 Years: 54000*6 + 3000*5 = 339,000
After t years: 54000*t + 3000*(t-1) = 57000 t - 3000

Please give brainliest, I really want to rank up, thank you!
Answer:
$358,000
Step-by-step explanation:
He makes $54k dollars "annual" = per year
Each year he stays he gets $3k worth of a raise
He stays 6 years so
3000 x 6 = 18k
54,000 x 6= 340,000
so then you just add
18,000 + 340,000=
358,000

3x+4y=-12 x-y=10 using elimination no links or download
Answer:
x = 4, y = -6
Step-by-step explanation:
Elimination Method
3x + 4y = -12 ---- (1)
x-y = 10 ---- (2)
(2) x 4:
4(x) 4(-y) = 4(10)
4x - 4y = 40 ---- (3)
(1) + (3):
3x + 4y + (4x - 4y) = -12 + 40
3x + 4y + 4x - 4y = 28
7x = 28
x = 28/7
x = 4
Sub x = 4 into (2):
(4) - y = 10
-y = 10 - 4
-y = 6
y = -6

If the shaded strip diagram represents 100% then which strip diagram represents 150%
Answer:
Your answer should be C.
Step-by-step explanation:
In order to make 150% you need a whole which represents the 100%. Which leaves B out of the question. A Is not close to half of a bar, which you can also eliminate. C and D are somewhat the same but it has to have the same amount of boxes shaded and unshaded, in this case D is 4 shaded and 2 unshaded which is wrong. So, your answer is C because there is 3 shaded and unshaded boxes in the model, hope this helps!
The diagram that represents 150% should be C.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
In order to make 150% we need a whole which represents the 100%. Which leaves B out of the question.
Option A Is not close to half of a bar, which we can also eliminate.
Option C and D are somewhat the same but it has to have the same amount of boxes shaded and unshaded,
In this case D is 4 shaded and 2 unshaded which is wrong.
Therefore, the answer is C because there is 3 shaded and unshaded boxes in the model.

Neutering dogs is a common surgical practice. The mean time to recover from the general anesthetic used is 26 hours. A veterinarian believes that since changing to a new anesthetic, the mean recovery time is shorter than before. From a random sample of 40 surgeries with the new anesthetic, she finds the mean recovery time was 25 hours with a standard deviation of 2.5 hours. What is the p-value for her hypothesis test
Answer:
0.005719
Step-by-step explanation:
H0 : μ = 26
H1 : μ < 26
Given that:
Population mean, μ = 26
Sample mean, xbar = 25
Sample standard deviation, s = 2.5
Sample size, n = 40
The test statistic :
(xbar - μ) / s/sqrt(n)
Test statistic :
(25 - 26) / 2.5/sqrt(40)
-1 / 0.3952847
Test statistic = - 2.5298
Using a Pvalue calculator from Z test statistic:

Domain: the set of all x-values
- this graph has arrows which means the domain is from -∞ to +∞ (-∞,+∞)
Range: the set of all y-values
- the graph extend continuously on the negative side so -∞ and it stops at 1 on the positive side (-∞,1)
Y-intercept: this point is where the graph crosses the y-axis, this is at (0,2)

Answer:
y = -2x + 7
Step-by-step explanation:
When 2 lines are perpendicular, the relationship between their slopes m1 and m2 may be stated as
m1m2 = -1
Given the line
y = 1/2 x + 8
Comparing with the general equation of a line y = mx + c where m is the slope and c is the intercept
m = m1 = 1/2
Hence the slope of the perpendicular line m2
= -1/1/2
= -2
Given that the line passes through the points (1,5)
using the equation
y - y1 = m (x - x1)
y - 5 = -2(x - 1)
y = -2x +2 + 5
y = -2x + 7
If x and y are two rational numbers such that x < y , then ______ is a rational number in between x and y.
Answer:
[tex]\dfrac{x+y}{2}[/tex]
Step-by-step explanation:
Let first number be x and another number is y.
A rational number is a fraction that can be expressed in the form of x/y.
A rational number between x and y is given by :
[tex]R=\dfrac{x+y}{2}[/tex]
So,
If x and y are two rational numbers such that x < y , then [tex]\dfrac{x+y}{2}[/tex] is a rational number in between x and y.

Answer:
mean = 5+9+9+6+6+11+8+4/7 = 8.29
median = 6
mode = 6
range = 11 - 4 = 7
Answer:
Step-by-step explanation:
5 , 9 , 6 , 6 , 11 , 8 , 4
Mean = sum of all data ÷ number of data
[tex]= \frac{5+9+6+6+11+8+4}{7}\\\\= \frac{49}{7}\\\\= 7[/tex]
Median: To find median, arrange in ascending order and medianis the middle term
4 , 5 , 6 , 6 , 8 , 9 , 11
Middle term = 4th term
Median = 6
Mode: a number that appears most often is mode
6 appears 2 times
Mode = 6
Range:
Range = maximum value - minimum value
= 11 - 4
= 7
Which expression is equivalent to 3t - 5 + 8t + 3 ?
Answer:
11t -2
Step-by-step explanation:
3t - 5 + 8t + 3
Combine like terms
3t +8t- 5 + 3
11t -2
Start by changing the problem to 3t + -5 + 8t + 3.
Now combine like terms.
Combine like terms → your numbers
and your "t" terms.
So 3t + 8t is 11t and -5 + 3 is -2.
So the answer is 11t - 2.
