Answer:
125%
this is the answer in percent form
if we take 140 as the 100%, what is 175 off of it in percentage?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 140 & 100\\ 175& x \end{array} \implies \cfrac{140}{175}~~=~~\cfrac{100}{x} \\\\\\ \cfrac{4}{5}=\cfrac{100}{x}\implies 4x=500\implies x=\cfrac{500}{4}\implies x=125[/tex]
find R=x^2/y when
y=3.8x10^5
x=5.9x10^4
The value of the expression R = x^2/y when y = 3.8 x 10^5 and x = 5.9 x 10^4 is 9.2 x 10^3
How to evaluate the expression?The expression is given as
R = x^2/y
Where
y = 3.8 x 10^5
x = 5.9 x 10^4
Substitute y = 3.8 x 10^5 and x = 5.9 x 10^4 in the equation R = x^2/y
So, we have
R = (5.9 x 10^4)^2/3.8 x 10^5
Evaluate the exponent
So, we have
R = 34.81 x 10^8/3.8 x 10^5
Evaluate the quotient
So, we have
R = 9.16052631579 x 10^3
Approximate the above expression
So, we have
R = 9.2 x 10^3
Hence, the value of the expression R = x^2/y when y = 3.8 x 10^5 and x = 5.9 x 10^4 is 9.2 x 10^3

The Leapin Lizards Center sells entrance tickets for $10.00 per child on Saturday nights. At capacity, the center can only hold 50 children during the 5:00-6:00pm time slot. The function L(c)=10c represents the amount of money Leapin Lizards makes on Saturday nights during the time slot.
Which statement best represents the range of the function in this context?
The statement that best represents the range of the function in this context is 0 <= L(c) <= 500
What is the range of a function?The range of a function is the set of output values of the graph.
This in other words mean the range of a function is the set of y values of the graph.
How to determine which statement best represents the range of the function in this context?The function is given as
L(c) = 10c
From the question, we understand that:
Maximum number of children = 50
This means that
c =50
So, we have
L(50) = 10 * 50
Evaluate
L(50) = 500
Hence, the statement that best represents the range of the function in this context is 0 <= L(c) <= 500

For which values of A, B, and C will Ax + By = C be a horizontal line through the point (−4, 2)?
The values of A, B, and C will Ax + By = C be a horizontal line through the point (−4, 2) are ( 0, B, 2B)
In the above question, a horizontal line is given whose equation is Ax + By = C which passes through a point (-4, 2)
We can make two observations from the given information of horizontal line passes through point (-4,2) which are as follows:
1. The slope of a horizontal line will be parallel to the x-axis whose slope will be, m=0.
2. The given point and the line meet at (-4,2).
Now as the point (-4,2) lie on the line it will satisfy the equation of the horizontal line
We get,
A(-4) + B(2) = C
-4A + 2B = C ..... eqn 1
Also, we can write the given equation in the slope-intercept form which is
y = mx + c
By = -Ax + C
y = [tex]\frac{-A}{C}[/tex]x + [tex]\frac{C}{B}[/tex]
So, we can imply that m = [tex]\frac{-A}{C}[/tex] = 0
A = 0
Putting this in eqn 1 we get,
-4A + 2B = C
0 + 2B = C
C = 2B
Hence, we conclude that values of A, B, and C will Ax + By = C be a horizontal line through the point (−4, 2) are ( 0, B, 2B)

Lisa’s square garden has an area of 64 square feet . Lisa increase each side of her square garden by 5 feet . What is the total area of the garden
Answer:
the total area of the enlarged garden is 324 square feet
Step-by-step explanation:
Lisa square garden has an area of 64 square feet. The formula for determining the area of a square is expressed as
Area = Length²
Length = √Area
Therefore, Length of each side of Lisa's garden is
√64 = 8 feet.
Lisa increases each side of her square garden by 5 feet. It means that the length of each side of the enlarged garden is 8 + 5 + 5 = 18 feet
Therefore, the total area of the enlarged garden would be
18² = 324 square feet

Suppose m 7=148°. Find m1 and m 2 and m4
Answer:
m<1 = 148
m<4 = 32
Step-by-step explanation:
<1 and <7 are alternate exterior angles. By the Alternate Exterior Angle Theorem, <1 and <7 are congruent and therefore m<1 = m<7. So m<1 = 148 degrees.
<3 and <7 are corresponding angles. By the Corresponding Angles Postulate, <3 and <7 are congruent and therefore m<3 = m<7. So m<3 = 148 degrees. <3 and <4 form a linear pair, and by the Linear Pair Postulate, <3 and <4 are supplementary and therefore m<3 + m<4 = 180. So m<4 = 180 - m<3 = 180 - 148 = 32 degrees.

Answer:
196 degrees, reflex.
Step-by-step explanation:
The angles fit around a point, therefore, they add up to 360 degrees.
Let [tex]x[/tex] be the size of the third angle.
[tex]x + 113 + 51 = 360 \\x + 164 = 360 \text{ / Subtract 164 on both sides} \\x + 164 - 164 = 360 - 164} \\x = 196[/tex]
The angle is larger than 180 degrees and smaller than 360 degrees, therefore, its a reflex angle.
Answer:
196 degrees, reflex.

He will use 18 teaspoons of baking powder for the oatmeal recipe
How to calculate the amount of baking flour ?A recipe requires 2 cups of flour and 2.5 cups of oats
For each cup he must add 1.5 teaspoons of baking powder
He uses 15 cups of oats
Each recipe uses 2 cups of flour, the teaspoons of baking powder used in one recipe is
1.5 × 2 = 3
2.5 cups of oats is used for one recipe, he uses 15 cups of oats, this means that the number of recipes is 6 (15/2.5)
Since the number of recipes is 6 and 3 teaspoon of baking powder is used for one recipe, then the number of teaspoons used is

Choose the expression that is equivalent to (6^-3/3^-2x6^2)to the 3rd
The required expression that is equivalent to (6^-3/3^-2x6^2) to the 3rd power is 3^3/2^3.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now the given expression is,
(6^-3/3^-2x6^2)to the 3rd power
or, we can write
(6^-3/3^-2x6^2)^3
Since, a^-1 = /a
Therefore we have
6^-3 = 1/6^3
3^-2 = 1/3^2
Therefore we get,
{(1/6^3)/(1/3^2) x 6^2}^3
Simplifying we get
{(3^2/6^3) x 6^2}^3
or, {(3^2 x 6^2)/6^3}^3
Solving we get
(3^2/6)^3
Now since,
3^2 = 9
Put in expression we get
(9/6)^3
or, (3/2)^3
therefore we get,
3^3/2^3
this is the required expression that is equivalent.
Thus, the required expression that is equivalent to (6^-3/3^-2x6^2) to the 3rd power is 3^3/2^3.

and quarters does Carlos have?
By resolution of systems of linear equations, Carlos has 6 quarters and 14 dimes in his pocket.
How many quarters and dimes does Carlos have in his pocket?
A dime is equivalent to 0.10 dollars and a quarter is equivalent to 0.05 dollars. In accordance with the statement, Carlos has 20 coins between dimes and quarters, whose algebraic equations are described below:
q + d = 20 (1)
q = 0.5 · d - 1 (2)
Where:
q - Number of quarters.d - Number of dimes.By (2) in (1):
(0.5 · d - 1) + d = 20
1.5 · d - 1 = 20
1.5 · d = 21
d = 14
By (2):
q = 0.5 · d - 1
q = 0.5 · 14 - 1
q = 7 - 1

f(x)=b x and g(x)=logbx are inverse functions. Explain why each of the following is true.
c. The inverse of f₁(x)=b x-h is not equivalent to a vertical stretch or compression of g .
The inverse of f₁(x)=b^(x-h) is not equal to a vertical stretch or compression of g: TRUE
What accurately do we mean by Logarithmic Functions?The logarithmic function is the inverse of the exponential function.A logarithm to the base b is the power to which b must be increased in order to obtain a specific number.For example, log28 is the power to which 2 must be raised to generate eight. Clearly, 23 = 8, so log28=3.So,
Given inverse function: f₁(x)=b^(x-h)
First, find out the inverse of this function.
So, let f₁(x) = yThen, y=b^(x-h)Switch the variables x & y as follows;
x=b^(y-h)Solve for y as shown below and take logarithm both sides:
log(x) = (y-h)log(b)y=h+ log(x)/log(b)So,
f₁^(-1)(x)= h+log(x)/log(b)f₁^(-1)(x)= h+logb(x)f₁^(-1) (x)= g(x)+hFrom the first equation we get the inverse of as f₁ follows:
f₁^(-1) (x)= g(x)+hTherefore, the statement "the inverse of f₁(x)=b^(x-h) is not equal to a vertical stretch or compression of g" is TRUE.

can someone explain how to answer this type of quadratic sequence step by step please
A sequence of events or things is a number of events or things that come one after another in a particular order. The nth term of
for 6,21,46,81 is 5n²+1.
What is sequence?A sequence of events or things is a number of events or things that come one after another in a particular order.
Write down the nth term of this quadratic number sequence.
6,21,46,81...
number sequence has nth term = an² + bn + c.
Confirm the sequence is quadratic. This is done by finding the second difference.
Sequence =6,21,46,81
1st difference = 15,25,35
2nd difference = 10,10
If you divide the second difference by 2, you will get the value of a.
10/2=5
So the first term of the nth term is 5n².
ext, substitute the number 1 to 4 into 5n².
n=1,2,3,4
5n²=5,20,45,80
Now, take these values (5n²) from the numbers in the original number sequence and work out the nth term of these numbers that form a linear sequence.
5n²+1=6,21,46,81.
Therefore nth term for 6,21,46,81 is 5n²+1.
