The diameter of a regulation soccer ball is about 8 and three-fifths inches. This number was graphed on a number line.
A number line going from negative 9 to positive 9. Point A is between negative 9 and negative 8, point B is between negative 7 and negative 6, point C is between 6 and 7, point D is between 8 and 9.
Which point could be the point representing the graph of the diameter of the ball?
A
B
C
D
Answers
Answer:
The answer is D....... between 8 and 9.
Answer:
D
Step-by-step explanation:
It is D because 8 3/5 is 8.6 in decimal form which is also right in between 9 and 8 which they are very close to 8.6. So there is not an exact number
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

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.

Question 25 options: The exponent 3 is an odd number. The base –2 is an even number. The base –2 is a negative number. The exponent 3 is a positive number.
Answers
Answer:
The base –2 is a negative number
Step-by-step explanation:
We need to solve the exponential expression (–2)³.
(–2)³ = -2×-2×-2
= -8
The final answer is -8. It is negative. It is because the base i.e. -2 is an even number. If the base is negative and the power is odd, the answer will be a negative number. Here, base is -2, power is 3. Hence, the correct option is (c) "The base –2 is a negative number".
Answer:
The exponent 3 is an odd number.
Step-by-step explanation:
Since the exponent (3) is an odd number, the answer will be negative. Answer: –8

Find the value of x and y
Answers
Answer: x=16, y=10
Step-by-step explanation:
To find the value of x and y, we need to know the angle properties. We know that 8x-14 and 5x+34 are equal to each other because of Alternate Exterior Angles. Now, we also know that 8x-14 and 5y+16 are supplementary angles, meaning they are equal to 180°. To solve, let's first find the value of x.
8x-14=5x+34 [subtract both sides by 5x]
3x-14=34 [add both sides by 14]
3x=48 [divide both sides by 3]
x=16
Now that we know x=16, we can find the value of y.
8x-14+5y+16=180 [plug in x=16]
8(16)-14+5y+16=180 [multiply]
128-14+5y+16=180 [combine like terms]
130+5y=180 [subtract both sides by 130]
5y=50 [divide both sides by 5]
y=10
Now, we know that x=16 and y=10.

David invested $340 in an account paying an interest rate of 2\tfrac{1}{8}2 8 1 % compounded continuously. Natalie invested $340 in an account paying an interest rate of 2\tfrac{3}{4}2 4 3 % compounded quarterly. After 17 years, how much more money would Natalie have in her account than David, to the nearest dollar?
Answers
Answer:
$53.83
Step-by-step explanation:
For David
David invested $340 in an account paying an interest rate of 2\tfrac{1}{8}2 8 1 % compounded continuously.
r = 2 1/8% = 17/8% = 2.125% = 0.02125
t = 17 years
P = $340
For Compounded continuously, the formula =
A = Pe^rt
A = Amount Invested after time t
P = Principal
r = interest rate
t = time
A = $340 × e^0.02125 × 17
A = $ 487.94
For Natalie
Natalie invested $340 in an account paying an interest rate of 2\tfrac{3}{4}2 4 3 % compounded quarterly.
r = 2 3/4 % = 11/4% = 2.75% = 0.0275
t = 17 years
P = $340
n = compounded quarterly = 4 times
Hence,
Compound Interest formula =
A = P(1 + r/n)^nt
A = Amount Invested after time t
P = Principal
r = interest rate
n = compounding frequency
t = time
A = $340 (1 + 0.0275/4) ^17 × 4
A = $ 541.77
After 17 years, how much more money would Natalie have in her account than David, to the nearest dollar?
This is calculated as
$541.77 - $ 487.94
= $53.83
Hence, Natalie would have in her account, $53.83 than David
write a function expressing how pressure change depending on the under water
Answers
Answer:
When diving in the ocean, you must consider how much pressure you will experience from diving a certain depth.
From the atmosphere, we experience about 14.7 pounds per square inch (psi) and for every foot we dive down into the ocean, we experience another 0.44 psi in pressure.
How far (in feet) can you dive without experiencing more than 58.7 psi of pressure on your body?
:
let d = the depth which gives 58.7 psi
.44d + 14.7 = 58.7
.44d = 58.7 - 14.7
.44d = 44
d = 44/.44
d = 100 ft

How many positive terms are in an arithmetic progression: 17.2; 17; 16.8
Answers
Answer:
3
Step-by-step explanation:
a = first term = 17.2
tn = last term = 16.8
d= common difference = -0.2
n = number of terms = ?
To find the number of positive terms, we'll use the formula;
tn = a + (n - 1) d
Substituting the figures,
=> 16.8 = 17.2 + (n -1) -0.2
=> 16.8 - 17.2 = (n - 1) - 0.2
=> -0.4 = (n - 1) - 0.2
=> -0.4/-0.2 = n - 1
=> n - 1 = 2
=> n = 3
Therefore, the number of positive terms in the sequence is 3

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

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
