Answer:
5 balls
Step-by-step explanation:
Given data
Diameter of ball= 2.6in
radius= 1.3 in
volume of ball= 4/3πr^3
Required
The number of balls that can be in the container
v=4/3*3.142*1.3^3
v= 4/3*3.142*2.197
v=27.61/3
v=9.20 in^3
The number of balls in the container is
=46.4/9.20

The temperature in Moscow was 2°C.Then it dropped to 8°C below zero.By how many degrees dis the temperature drop ?
Answer:
Step-by-step explanation:
From 2 to 0 =2
From 0 to - 8=8
Total =2+8=10
The temperature dropped -10 °C in Moscow.
What is subtraction?Subtraction is a mathematic operation. Which is used to remove terms or objects in an expression.
Given:
The temperature in Moscow was 2 °C.
Then it dropped to 8 °C below zero.
That means, the temperature is -8 °C.
To find the temperature drop in number:
Let n be the required number.
Then using subtraction operation,
n = -8 °C - 2 °C
n = -10 °C.
Therefore, -10 °C is the temperature.

Is A = 4b proportional
Answer:
Yes, it is proportional.
Step-by-step explanation:
Anything with "A =" is always going to be proportional.
Answer:
I...think so?
if you isolate b then b = [tex]\frac{A}{4}[/tex] or [tex]\frac{1}{4}[/tex]
if you isolate A like already shown then A = 4b
Can someone help me with these definitions?
Answer:
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000. So 4000 can be written as 4 × 10³. This idea can be used to write even larger numbers down easily in standard form. Small numbers can also be written in standard form.
Factored form, the product of a constant and two linear terms: or. The parameters and are the roots of the function (the x-intercepts of the graph ). Converting a quadratic function to factored form is called factoring.
The y -intercept of a graph is the point where the graph crosses the y -axis. (Because a function must pass the vertical line test , a function can have at most one y -intercept . ) The y -intercept is often referred to with just the y -value.
The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis. and vertex is
In geometry, a vertex (in plural form: vertices or vertexes), often denoted by letters such as, is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.

Mark borrowed $7400 at an interest rate of 10.5% for 1/4 of a year how much interest will he pay when his loan is paid off
Answer:
$194.25
Step-by-step explanation:
Given data
Principal= $7400
Rate= 10.5%
time= 1/4 years
The simple interest formula is given as
SI= PRT/100
substitute
SI= 7400*10.5* 0.25/100
SI= 19425/100
SI= $194.25
Hence Mark will pay $194.25

Aaron has $150 at the start of the week. By the end of the week, he has 30% more money. How much
total money does he have at the end of the week? Show work, using any method.
Answer:
$195
Step-by-step explanation:
To solve a percent problem, you can use the equation: part %
------- = -----
whole 100
You want to find 30 percent, so the % would be 30. You also want to find 30% of 150, so the whole would be 150 and the part would be x. Cross multiply to get 100x = 4500. Then, divide 4,500 by 100. The equation should look like this: x = 45. Add 45 to $150 to get $195. So Aaron has $195 at the end of the week.

A sprinkler can water between 1 and 130 square yards of a lawn. The length L in inches of rotating pipe needed to water A square yards is given by the function L=119.75 square root of A. How much area can be watered if the length of the pipe is 600, 900, or 1,000 inches long?
Answer:
[tex]25.1\ \text{inches}^2[/tex]
[tex]56.5\ \text{inches}^2[/tex]
[tex]69.7\ \text{inches}^2[/tex]
Step-by-step explanation:
The length of the pipe is given by the function
[tex]L=119.75\sqrt{A}[/tex]
where A is the area
[tex]A=(\dfrac{L}{119.75})^2[/tex]
For [tex]L=600\ \text{in}[/tex]
[tex]A=(\dfrac{600}{119.75})^2\\\Rightarrow A=25.1\ \text{inches}^2[/tex]
Area watered when L = 600 inches is [tex]25.1\ \text{inches}^2[/tex]
For [tex]L=900\ \text{in}[/tex]
[tex]A=(\dfrac{900}{119.75})^2\\\Rightarrow A=56.5\ \text{inches}^2[/tex]
Area watered when L = 900 inches is [tex]56.5\ \text{inches}^2[/tex]
For [tex]L=1000\ \text{in}[/tex]
[tex]A=(\dfrac{1000}{119.75})^2\\\Rightarrow A=69.7\ \text{inches}^2[/tex]
Area watered when L = 1000 inches is [tex]69.7\ \text{inches}^2[/tex]
There are 3 tons of corn seed shared evenly between 3 farmers. How many pounds of corn seed does each farmer get?
20 pounds
200 pounds
2,000 pounds
20,000 pounds
Answer:
2,000
Step-by-step explanation:
To know how much is 3 tons you must multiply 20,00 by 3. That is 6,000. Now you must split that in that by 3. Farmer 1: 2,000, Farmer 2: 2,000, Farmer 3: 2,000. We know this because if you add them all together it is 6,000.

g(a) = 4a - 5; Find a when g(a)=-37
Answer:
a = -8
Step-by-step explanation:
g(a) = -37
g(a) = 4a - 5
g(a) = 4a - 5
-37 = 4a - 5
-37 + 5 = 4a
-32 = 4a
a = -32/4
a = -8

1. Rewrite in slope-intercept form. *
- 7x + 2y = 8
Answer:
y = [tex]\frac{7}{2}[/tex] x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 7x + 2y = 8 ( add 7x to both sides )
2y = 7x + 8 ( divide all 3 terms by 2 )
y = [tex]\frac{7}{2}[/tex] x + 4 ← in slope- intercept form

We are required to solve the following equation:
[tex]\displaystyle 7^7\cdot 7^5=\frac{(7^n)^4}{7^4}[/tex]
Operating:
[tex]\displaystyle 7^{7+5}=\frac{7^{4n}}{7^4}[/tex]
[tex]\displaystyle 7^{12}=7^{4n-4}[/tex]
Equating the exponents:
4n - 4 = 12
Adding 4:
4n = 16
Dividing by 4:
n = 4
What is the slope of the line that passes through the points (-10, -8) and
(-8, -16)? Write your answer in simplest form.
Answer:
-4
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-16 + 8) / (-8 + 10)
-8 / 2
= -4
So, the slope is -4
