C. NegativeB. PositiveC. NegativeC. NegativeA. ZeroExplanation:
1.) 3.2 - 5.7 = -2.5
2.) 4.25 - (-2.3) = *double negative = positive* = +6.55
3.) -0.18-2 = -2.18 *2 negatives will add numbers, but the sign remains negative*
4.) -9 + 2.5 = -6.5 *since 9 is greater, we will use its sign, then subtract the two*
5.) (-9 + 5) +4 = -4 +4 = 0
3.2-5.7=C
4.25-(-2.3)=C
-0.18-2=C
-9+2.5=C
-9+5=4=B

Divide the square root of 81 by the difference between the product of-1 and -3 and the square root of 4
Answers
Answer: [tex]\frac{9}{1}[/tex]
Step-by-step explanation:
FIrst find the square root of 81.
[tex]\sqrt{81} = 9[/tex]
The square root of 81 is 9.
FInd the product of -1 and -3 by multiplying the -1 by -3.
-1 * -3 = 3
next find the square root of 4.
[tex]\sqrt{4} = 2[/tex]
Now it said divide the square root of 81 which is 9 by the difference between 3 and 2 and the difference between 3 and 2 two is 1.
Thos means that the answer will be 9/1.

what are the dimensions of the largest rectangular field that can be enclosed with 64m of wire?
Answers
Step-by-step explanation:
perimeter = 2*length + 2*width
area = length*width
perimeter = 64
Rectangular means all the corners have to be right angles.
If we say it can be a square, then...
perimeter = 4*side
64 / 4 = side
side = 16 meters
So the dimensions would be 16 m x 16 m

Dominic is looking to buy a cell phone and is comparing cellular plans. Company A charges a $175 start-up fee and
$75 per month for service. Company B does not have a start-up fee, but it charges $97 per month.
175+75m
Use the inequality < 97 to find how many months it will take before the average monthly cost of Company A
m
is less than Company B.
Enter your answer as a number, like this: 42
Answers
Answer:
4
Step-by-step explanation:
add up the cost of month one for A then keep adding 75 do the same for B
For less than 8 months the cost of company A remains less than company B.
Given that,
Company A charges a $175 start-up fee and $75 per month for service. Company B does not have a start-up fee, but it charges $97 per month.
To determine how many months it will take before the average monthly cost of Company A.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
According to the question,
175 + 75m < 97m
175 < 97m - 75m
175 < 22m
8 < m
Thus, for less than 8 months the cost of company A remains less than company B.

Line FG is represented by the equation 8x+3y=10. Which value is the slope of a line perpendicular to line FG
A.-3/8
B.-1/8
C.3/8
D.8/3
Answers
Answer:
The correct answer is 3/8
Step-by-step explanation:
It was in my practice and I had gotten it correct.
Answer:
C. 3/8
Step-by-step explanation:
Since line FG is represented by an equation in standard form, Ax + By = C, the slope of the line is equal to -a/b.
So, the slope of line FG is -8/3
Perpendicular lines have opposite reciprocal slopes. So, a line perpendicular to line FG will have a slope equal to 3/8.
Jose unlocks his cellphone by placing his right thumb on a square of 1 centimeter by 1 centimeter at the center of the screen. Upon recognizing his thumbprint, the square expands outward. The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds. What is the perimeter of the square after 1.5 seconds? 16.8 centimeters 19.2 centimeters 20.8 centimeters 29.2 centimeters
Answers
Answer:
Step-by-step explanation:
We can solve this question using proportion
Perimeter of the square/Time is takes to unlock
We are told in the question that:
The cellphone unlocks when the perimeter reaches 32 centimeters, taking a total of 2.5 seconds.
Hence, the perimeter of the square after 1.5 seconds is:.x = unknown
32/2.5 = x/1.5
Cross Multiply
2.5x = 32 × 1.5
x = 32 × 1.5/2.5
x = 19.2 centimeters
MODELING WITH MATHEMATICS A farmer plants a garden that contains corn and pumpkins. The total area (in square
feet) of the garden is modeled by the expression 2x2 + 5x + 4. The area of the corn is modeled by the expression
x2 – 3x + 2. Write an equation in standard form that models the area A of the pumpkins.
Answers
Answer:
The equation in standard form that models area of pumpkins is:
[tex]A_p = A_G - A_c[/tex]
and the area is: [tex]x^2+8x+2[/tex]
Step-by-step explanation:
Given that the garden has corn and pumpkins
The expressions are:
Total area of garden: [tex]A_G = 2x^2+5x+4[/tex]
Area of Corn: [tex]A_c = x^2-3x+2[/tex]
Area of Pumpkins: [tex]A_p = ?[/tex]
The sum of areas of corn and pumpkins is the total area of the garden.
It can be expressed mathematically as:
[tex]A_G = A_c+A_p[/tex]
If we have to find the area of pumpkins,
[tex]A_p = A_G - A_c[/tex]
Putting the values
[tex]A_p = (2x^2+5x+4) - (x^2-3x+2)\\A_p = 2x^2+5x+4-x^2+3x-2\\A_p = 2x^2-x^2+5x+3x+4-2\\A_p = x^2+8x+2[/tex]
The equation in standard form that models area of pumpkins is:
[tex]A_p = A_G - A_c[/tex]
and the area is: [tex]x^2+8x+2[/tex]
The equation in standard form that models the area A of the pumpkins is x² + 8x + 2
From the question, we are given the following parameters
Area of the garden = 2x² + 5x + 4
Area of the corn = x² – 3x + 2
To get the area A of the pumpkin, we will take the difference in the areas as shown:
A = Area of garden - Area of corn
A = (2x² + 5x + 4) - (x² – 3x + 2)
A = 2x² - x² + 5x + 3x + 4 - 2
A = x² + 8x + 2
Hence the equation in standard form that models the area A of the pumpkins is x² + 8x + 2

Answers
Answer:
Step-by-step explanation:
1. Simplifying
8x + 2y = 14
2. Solving
8x + 2y = 14
3. Solving for variable 'x'.
4. Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
8x + 2y + -2y = 14 + -2y
5. Combine like terms: 2y + -2y = 0
8x + 0 = 14 + -2y
8x = 14 + -2y
6. Divide each side by '8'.
x = 1.75 + -0.25y
7. Simplifying
x = 1.75 + -0.25y

Answers
Answer:
The first step is adding two to both sides to further isolate the variable.
Step-by-step explanation:
You want m/5=10 so you can multiply 5 on both sides and find what m equals which is 50 in this instance.
Answer:
Step-by-step explanation:
m/5 -2=8 I would first add 2 to both sides
m/5=10 Then multiply both sides by 5 to clear out the fraction.
m=50

Gravitational acceleration g = 32 ft/s²
Computation:
h = ut + 1/2(gt²)
555 = 1/2(30)(t²)
Time taken t = 5.88 sec (Approx)
