Farrah has 150 dimes, 250 nickels, and 400 pennies.
Complete the table to show the ratio of the number of pennies to the total number of coins.
Answer:
1:2
Step-by-step explanation:
In total, there are 800 coins. 400 of those coins are pennies. The ratio is 400 pennies to 800 coins. Since 400 is half of 800, this can be simplified down to 1 penny to 2 coins, or 1:2.
(6 ten thousands 3 hundreds) × 10 =
Answer:
630000
Step-by-step explanation:
We obtain 603000 when we multiply (6 tens of thousands three hundreds) by 10.
What is meant by standard form?A number is ranked or assigned to the place "ones tens hundreds thousands" when it comes to huge or tiny numbers. The position of numbers is referred to by the place value of a number, which indicates the position of a specific digit in a number that can be ones, tens, hundreds, or thousands.Each digit in a number has a distinct position and value. A number may have multiple digits. Starting from the right, the first digit will be in the ones place, the second in the tens place, and the third in the hundreds place.Given,
(6 ten thousands three hundreds) × 10
Simplifying the above equation, then we get
= 603000.
Tens of thousands could be used to refer to a bigger sum (typically between 10,000 and 99,999).

A. 4s + 3
B. 4 + 3s
C. 4 – 3s
D. 3s – 4
Answer:
B. 4+3s
Step-by-step explanation:
The expression that represents the number of seeds that has been planted by Israel is 4 + 3s. Hence, Option B is correct.
What is an expression?A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression in mathematics.
Mathematical symbols can represent variables, operations, functions, brackets, punctuation, and grouping to help specify the logical syntax and order of operations.
But in contemporary mathematics, and particularly in computer algebra, formulae are seen as expressions that can be evaluated as true or false, depending on the values given to the variables present in the expressions.
In the garden, Israel sowed 4 tomato seeds. Then Israel scattered flower seeds throughout the gardens of the three neighbors. Here neighbors will be denoted as x. For this the most suitable expression will be 4 + 3s.
Therefore, Option B is correct.

9. The Science Club needs to rent a bus for a field trip. Main Street Buses charges a $40 rental fee, plus $2 per mile. County Bus Line charges a $20 rental fee, plus $3 per mile. For what number of miles will the total charge be the same? What will that charge be?
Answer:
20 miles $80
Step-by-step explanation:
20 miles
P%5Bc%5D%2820%29=20%2B3%2820%29=20%2B60=80
$80
Answer:
M=Main buses
C=Country buses
Step-by-step explanation:
so the charges from Main are $40 fee, then additional $2 for every mile you drive it for, so M = 40 + 2m
if your mileage is 20miles, when 2*20 is the charge
if your mileage is 50miles, when 2*50 is the charge
if your mileage is 1000miles, when 2*1000 is the charge
if your mileage is "m" miles, when 2*m is the charge
and County charges are $20 fee, then additional $3 for every mile... .so then C = 20 + 3m
if your mileage is 20miles, when 3*20 is the charge
if your mileage is 50miles, when 3*50 is the charge
if your mileage is 1000miles, when 3*1000 is the charge
if your mileage is "m" miles, when 3*m is the charge
so, their total charge is M and C respectively
when are the charges equal? well, when M = C
or
40 + 2m = 20 + 3m
solve for "m", to see at how many miles that happens
what will the charge be? plug that value for "m" on either, to get the charge

Which function is the inverse of f(x)=x²-16 if the domain is f(x)>0?
Answer:
[tex]f^{-1}(x)=\sqrt{x+16}[/tex]
Step-by-step explanation:
[tex]f(x)=x^2-16[/tex]
The inverse of the function [tex]f[/tex] is [tex]f^{-1}[/tex]
The Range of the inverse function [tex]f[/tex] will be the Domain of the function [tex]f[/tex]
[tex]Ran(f^{-1}) = [0, \infty)[/tex]
The inverse of
[tex]f(x)=x^2-16[/tex]
is
[tex]f^{-1}(x)=\sqrt{x+16}[/tex]
Note that if the domain of the function [tex]f[/tex] where all the Real numbers, the inverse would be
[tex]f^{-1}(x)=\pm\sqrt{x+16}[/tex]
Answer:
Inverse of [tex]f(x)=x^2-16[/tex] is [tex]f^{-1}(x)=\sqrt{x+16}[/tex]
Option A is correct option.
Step-by-step explanation:
We need to find inverse of [tex]f(x)=x^2-16[/tex]
For finding inverse replace f(x) with y
[tex]y=x^2-16[/tex]
Now, solve for x
Adding 16 on both sides
[tex]y+16=x^2-16+16\\y+16=x^2\\=> x^2=y+16[/tex]
Taking square root on both sides:
[tex]x^2=y+16\\\sqrt{x^2} =\sqrt{y+16} \\x=\sqrt{y+16}[/tex]
Now replace x with f^{-1}(x) and y with x
[tex]f^{-1}(x)=\sqrt{x+16}[/tex]
So, inverse of [tex]f(x)=x^2-16[/tex] is [tex]f^{-1}(x)=\sqrt{x+16}[/tex]
Option A is correct option.

Point XXX is located at (3, 2)(3,2)left parenthesis, 3, comma, 2, right parenthesis. Point YYY is located at (3, -8)(3,−8)left parenthesis, 3, comma, minus, 8, right parenthesis. What is the distance from point XXX to point YYY?
Answer:
10
Step-by-step explanation:
Given that:
Point X = (3, 2)
Point Y = (3, - 8)
Distance of point X to Y:
Distance = √(x2 - x1)^2 + (y2 - y1)^2
X1 = 3 ; y1 = 2 ; x2 = 3 ; y2 = - 8
Distance = √(3 - 3)^2 + (-8 - 2)
Distance = √(0)^2 + (-10)^2
Distance = √0 + 100
Distance = √100
Distance = 10

Given:18x-2(3x+1)=5x-16
Prove:x=-2
(Include statements and reasons)
Answer:
Step-by-step explanation:18x−2(3x+1)=5x−16
18x+(−2)(3x)+(−2)(1)=5x+−16
18x+−6x+−2=5x+−16
(18x+−6x)+(−2)=5x−16
12x+−2=5x−16
12x−2=5x−16
Step 2: Subtract 5x from both sides.
12x−2−5x=5x−16−5x
7x−2=−16
Step 3: Add 2 to both sides.
7x−2+2=−16+2
7x=−14
Step 4: Divide both sides by 7.
