Answer
The answer is 17.
Explanation
The absolute value of any number is taking the positive part of any number. For example, the absolute value of -2 = | -2 | = 2, the absolute value of -99 = | -99 | = 99.
So, the absolute value of -17 = | -17 | = 17.

A circular garden with a radius of 4 ft is planted in the center of a 10 ft square. The part of the square that is NOT the garden is covered with small white rocks. what is the area of the region covered with white rocks?
First, draw a diagram to visualize the situation:
The area of the region covered with small rocks can be found by subtracting the area of the circle from the area of the square.
The area A_s of a square with side L is given by:
[tex]A_s=L^2[/tex]And the area A_c of a circle with radius r is given by:
[tex]A_c=\pi r^2[/tex]Replace r=4ft and L=10ft into the equations to find the area of the circle and the square:
[tex]\begin{gathered} A_s=(10ft)^2=100ft^2 \\ A_c=\pi(4ft)^2=16\pi ft^2\approx50.265ft^2 \end{gathered}[/tex]Finally, subtract the area of the circle from the area of the square to find the area of the region covered with rocks:
[tex]A=A_s-A_c=100ft^2-16\pi ft^2\approx49.7ft^2[/tex]Therefore, the area of the region covered with rocks is exactly 100-16π square feet, which is approximately equal to 49.7 square feet.

Describe in words where cube root of 30 would be plotted on a number line.
Between 3 and 4, but closer to 3
Between 3 and 4, but closer to 4
Between 2 and 3, but closer to 2
Between 2 and 3, but closer to 3
Answer:
A) Between 3 and 4, but closer to 3======================
First, find the cubes of 2, 3 and 4 and then compare them with 30.
2³ = 8,3³ = 27,4³ = 64We see that 30 is between 27 and 64 and is closer to 27:
27 < 30 < 64Therefore cube root of these numbers are:
∛27 < ∛30 < ∛643 < ∛30 < 4So the ∛30 is between 3 and 4 and closer to 3.
Correct answer choice is A.
Answer:
A) Between 3 and 4, but closer to 3.
Step-by-step explanation:
A perfect cube is the result of multiplying the same integer three times.
First few perfect cubes: 1, 8, 27, 64, 125, etc.To estimate the value of the cube root of a number, find the perfect cubes above and below the number:
The perfect cubes either side of 30 are:
27 < 30 < 64Therefore, the cube roots are:
[tex]\implies \sf \sqrt[3]{27} < \sqrt[3]{30} < \sqrt[3]{64}[/tex]
[tex]\implies \sf 3 < \sqrt[3]{30} < 4[/tex]
As 30 is closer to 27 than 64, the cube root of 30 is closer to the cube root of 27 than the cube root of 64.
Therefore, the cube root of 30 would be plotted on a number line:
between 3 and 4, but closer to 3.Every 3 months, homeowners in boice pay $46.00 for service provided by the city. how much do homeworkers pay in one year? (1 year = 12 months)
We were told that in every 3 months, homeowners in boice pay $46.00 for service provided by the city.
Given that there are 12 months in a year, the number of 3 months in a year would be
12/3 = 4
This means that $46 would be paid 4 times in a year.
Thus, the amount that the homeworkers would pay in a year is
4 * 46 = $184

If $13,025 represents the total cost of making x hamburgers, which equation can be used to find the number of hamburgers produced?A. 13,025=2.05+2,000 xB. 13,025=2.05 x+2,000C. 13,025 x=2.05+2,000D. 13,025=2.05+2000 x
Answer:
(B)13,025=2.05x+2,000
Explanation:
The cost of making one hamburger = $2.05
The cost of making two hamburgers = $2.05 x 2
Therefore:
The cost of making x hamburgers = $2.05x
Since there is an additional cost of $2,000 for facility expenses.
The total cost will be:
[tex]2.05x+2000[/tex]If $13,025 represents the total cost of making x hamburgers, then:
[tex]13,025=2.05x+2000[/tex]This is the equation that can be used to find the number of hamburgers produced.
The correct choice is B.

For Monday morning's staff meeting, Jim bought 3 bags of bagels and 3 packages of cream cheese and paid $16.50 (excluding sales tax).For Friday's meeting, he bought 5 bags of bagels and 2 packages of cream cheese and paid $22.25 (again, excluding sales tax). How much dobags of bagels and packages of cream cheese cost?
Answer:
Explanation:
Let the price of one bag of bagel = b
Let the price of one package of cream cheese = c
3 bags of bagels and 3 packages of cream cheese costs $16.50.
[tex]3b+3c=16.50\cdots(1)[/tex]5 bags of bagels and 2 packages of cream cheese costs $22.25.
[tex]5b+2c=22.25\cdots(2)[/tex]Thus, we derive a system of two linear equations which we then solve for b and c.
[tex]\begin{gathered} 3b+3c=16.50\operatorname{\cdots}(1) \\ 5b+2c=22.25\operatorname{\cdots}(2) \end{gathered}[/tex]Multiply equation 1 by 5 and equation 2 by 3.
[tex]\begin{gathered} 15b+15c=82.5 \\ 15b+6c=66.75 \end{gathered}[/tex]Subtract to eliminate b.
[tex]9c=15.75[/tex]Divide both sides by 9:
[tex]\begin{gathered} \frac{9c}{9}=\frac{15.75}{9} \\ c=1.75 \end{gathered}[/tex]Next, substitute c=1.75 into equation 1.
[tex]\begin{gathered} 3b+3c=16.50 \\ 3b+3(1.75)=16.50 \\ 3b=16.50-3(1.75)=11.25 \\ b=\frac{11.25}{3}=3.75 \end{gathered}[/tex]The price per bag of bagel is $3.75 and the price per package of cream cheese is $1.75.
The total bill for repairing Mark’s TV was $211. The repair shop charges $25 an hour for labor plus $16 for parts. How many hours of labor did it take to repair Mark’s TV? Write it in an equation.25/16x = 21125 - 16x = 21125x – 16 =21125x + 16 = 211
Solution:
Given the total, T is $211;
One hour of labor is $25. So, x hours is $25x
Then, the cost of parts is $16.
Thus;
[tex]25x+16=211[/tex]I need 5 points. the vertex, 2 to the left, and 2 to the right
Graph the parabola
[tex]\begin{gathered} y=x^2-10x+27 \\ f(x)=ax^2+bx+c \end{gathered}[/tex]In order to find the vertex (h,k), we can use this formula
[tex]\begin{gathered} h=\frac{-b}{2a} \\ k=f(h) \end{gathered}[/tex]where,
a = 1
b = -10
c = 27
then, the vertex (h,k) is
[tex]\begin{gathered} h=-\frac{-10}{2\cdot1}=\frac{10}{2}=5 \\ k=f(5)=5^2-10\cdot5+27=25-50+27=2 \end{gathered}[/tex]Therefore, vertex is the point (h,k) = (5,2)
Now, we just need two points to the left and two points to the right of this point
for example, when x = 3, then y = 6
[tex]f(3)=3^2-10\cdot\: 3+27=6[/tex]when x = 4, then y = 3
[tex]f(4)=4^2-10\cdot\: 4+27=3[/tex]when x = 6, then y = 3
[tex]f(6)=6^2-10\cdot\: 6+27=3[/tex]when x = 7, then y = 6
[tex]f(7)=7^2-10\cdot\: 7+27=6[/tex]Thus, the set of 5 points is the following:

slope of line(m) = 2 and intercept on y axis is -2 that is 2 unit in negative y axis.
Equation of line in slope intercept form:
Slope:
Slope is known as tangent of an angle made by positive X-axis.
We know equation of line in slope and intercept form is,
y = mx + b
where,
m is slope of line
b is intercept on y axis

Answer:
The dec
Explanation:
Given that Lisa opened an investment account with $8400, at the end of the year, the amount in the account had decreased by 24.5%. We want to know how much the decrease is, and how much was in her account at the end of last year.
All we are required to find is what value is 24.5% of $8400
24.5% is the same as:
[tex]\frac{24.5}{100}[/tex]24.5% of $8400 is now:
[tex]\begin{gathered} \frac{24.5}{100}\times8400 \\ \\ =24.5\times84 \\ =2058 \end{gathered}[/tex]Therefore 24.5% of $8400 is $2058
This amount is the decrease.
Finally, at the end of last year, the amount in her account is:
$8400 - $2058 = $6342
Answer: If you do 8400 - 24.5% you get 6342. Then if you do 8400 - 6342 you get 2058. So her account decreased by $2,058 and she had $6342 left in her account at the end of the year.
