1 place to the right of a decimal point is the tenths, so you would multiply 7 by 1/10.
2 places to the right of the decimal point is the hundredths place, so you would multiply 23 by 1/100
The correct answer is D.
Can someone help me with these problems
2) angles are vertical so they are congruent- 7x-27= 4x+12 --> subtract 4x from both sides so 3x-27=12 --> add 12 to both sides so 3x=39 (divide both sides by 3) so then x= 13
3) again, vertical angles so 8x-120= 4x+16 --> subtract 4x so that 4x-120=16 --> add 120 to both sides and then 4x=136, divide both by 4 and x= 34

Little Melinda has nickels and quarters in her bank. She has two
fewer nickels than quarters. She has $3.50
in the bank. How many coins of each type does she have?
How many quarters does she have?
A) N +2 = Q which equals
A) N -Q = -2
B) .05N +.25Q = 3.50 multiplying A) by .25
A) .25N -.25Q = -.5 then adding A) and B)
.30N = 3
Nickels = 10 Quarters = 12
*************DOUBLE CHECK ***************
.05 nickels = $0.50 .25 Quarters = $3.00
Melinda has 12 quarters and 10 nickels in her bank, totaling $3.50. By setting up and solving equations based on the values of the coins, we were able to determine the exact number of each type of coin.
Explanation:Little Melinda has nickels and quarters in her bank, with two fewer nickels than quarters. The total amount of money she has is $3.50. To determine how many coins of each type she has, we need to set up equations based on the values of the coins and the given conditions.
Let's define:
Q = number of quarters
N = number of nickels
Since each quarter is worth 25 cents and each nickel is worth 5 cents, we have the following equations:
1. N = Q - 2 (since she has two fewer nickels than quarters)
2. (5 × N) + (25 × Q) = 350 cents (because the total amount is $3.50)
Substitute the first equation into the second to find the number of each coin:
5(Q - 2) + 25Q = 350
5Q - 10 + 25Q = 350
30Q - 10 = 350
30Q = 360
Q = 12
Then, substitute Q = 12 into the first equation to find N:
N = 12 - 2
N = 10
Therefore, Melinda has 12 quarters and 10 nickels.
Solve for a: 3a+4bc-d=5a-8j
3a + 4bc - d = 5a - 8j
Add d to both sides.
3a + 4bc = 5a - 8j + d
Subtract 4bc from each side.
3a = 5a - 8j + d - 4bc
Subtract 5a from both sides.
-2a = -8j + d - 4bc
Divide both sides by -2
a = [tex]\frac{(-8j -4bc + d)}{-2}[/tex]
A=2bc+-1/2d+4j would be your answer

which of the following represents this function written in standard form? y=3(x-1)(x+6)
Answer:
y = 3x^2+15x-18
Step-by-step explanation:
Parabola has an equation with one variable in degree 2 and other in degree 1.
Given that y=3(x-1)(x+6) is the function.
y is of degree 1 and x of degree 2
Standard form of these types of parabolas would be
y =ax^2+bx+c.
To make the given equation in standard form, we multiply all factors on the right side
y = 3(x-1)(x+6) = 3(x^2+5x-6)
= 3x^2+15x-18
a=3 b = 15 and c =-18
y = 3x^2+15x-18 is the standard form of the parabola
Answer:
y = 3x^2 + 15x - 18
Step-by-step explanation:
To represent the function y = 3 (x - 1) (x + 6), start by by expanding the equation by multiplying the common factor with each term inside the brackets to get:
y = 3 (x - 1) (x + 6)
y = (3x - 3) (x + 6)
Now multiply both the terms with each other to get:
y = 3x^2 + 18x - 3x - 18
Arrange the like terms together and add them:
y = 3x^2 + 15x - 18
Hence, y = 3x^2 + 15x - 18 is the standard form of the given function.
Which point is on the graph of f(x)=3x5^x?
By substituting x=1 into the function f(x)=3x5^x, we find that the point (1,15) is on the graph.
To find a point that lies on this graph, we can select a value for x, substitute it into the function, and calculate the corresponding y value. Let's try x=1:
f(1) = 3(1)51 = 3(5) = 15.
Therefore, the point (1,15) is on the graph of f(x)=3x5^x.

Answer:
1. The fixed costs is $40 and the cost per mile is [tex]\$\frac{3}{2}[/tex].
2.Therefore, the coffees did they sell is, 85 coffees
Step-by-step explanation:
1. To find the fixed cost and Cost per mile.
Since, a shipping company charges a fixed amount for their services and a certain amount per mile , they must travel.
Let the number of fixed amount be x and the certain amount per mile be y
then, the general linear equation for this we have:
[tex]x+y=C[/tex] where C is the charges cost by the shipping company.
It is given that for a 50 mile trip company costs $115 and an 80 mile trip costs $157.
we have an equation in linear form from the above data:
[tex]x+50y=\$115[/tex] .....(1)
[tex]x+80y=\$157[/tex] ....(2)
Now, solving these equation simultaneously we get,
[tex]y=\frac{3}{2}[/tex]
Substitute the value of y in equation (1),
[tex]x+50\times\frac{3}{2}=\$115[/tex]
[tex]x+75=\$ 115[/tex]
⇒[tex]x=\$40[/tex]
Therefore, the fixed costs is $40 and the cost per mile is [tex]\$\frac{3}{2}[/tex].

[tex]x+y=295[/tex]
[tex]0.75x+0.50y=200[/tex]
Solving these equation simultaneously we get the value of y=85
Therefore, the coffees did they sell is, 85 coffees

Justin and Desiree each wrote a ratio comparing the numbers of students and tables in their classroom. There are 6 tables in the room with 4 students at each table.0
Answer: 4:1
Step-by-step explanation:
Given:- Number of tables in the classroom=6
Number of students on each table = 4
thus number of students in the classroom =6×4=24 students
Now ratio of numbers of students to the tables in the classroom= numbers of students/tables in the classroom=24/6=4/1=4:1
Ratio of numbers of students to the tables in the classroom= 4:1
The temperature on a summer afternoon is 85°F. Define a variable and write an expression to find the temperature after it changes. Then evaluate your expression for a decrease of 11 degrees Fahrenheit.
11 – c; 11 – (–85) = 74; 74°F
85 – c; 85 – (–11) = 96; 96°F
85 + c; 85 + (–11) = 74; 74°F
11 + c; 11 + (–85) = 96; 96°F
B.) Any temperature change is the original temperature plus the numerical value of the change. (temp + change) If it is an increase, the number will be positive. If it is a decrease, the number will be negative.
Since there is a decrease of 11, c would be replaced with -11. When you plug this into your expression (85 + c: 85 + -11), the answer to this would be 74.
hope it helps
Final answer:
Explaining how to define a variable, write an expression, and evaluate the temperature after a decrease in Fahrenheit degrees.
Explanation:
Variable: Let c represent the temperature change.
Expression: To find the new temperature after a decrease of 11°F, the expression is 85 - c.
Evaluation: By substituting c with -11 (decrease of 11°F), 85 - (-11) equals 96°F.
The cube of the product of 3 and a number.
The cube of the product of 3 and a number is expressed as (3x)³ or 27x³, which involves cubing the numeric part and multiplying the exponent of the variable by 3.
The question is asking about the volume of a cube with sides of length a and also about the process of cubing the product of a number and three. When we cube a product, such as 3 times an unknown number, we are calculating the result of multiplying that product by itself three times.
For example, if our number is x, we would express this as (3x)³ or 27x³. This is because when we cube a product, we cube the numeric part as usual, obtaining 3³ which is 27, and we multiply the exponent of the exponential term by 3, thus x becomes x³.
Simplify the expression. Write your answer as a power.

What is 15-5(4x-7)=50
Simplifying
15 + -5(4x + -7) = 50
Reorder the terms:
15 + -5(-7 + 4x) = 50
15 + (-7 * -5 + 4x * -5) = 50
15 + (35 + -20x) = 50
Combine like terms: 15 + 35 = 50
50 + -20x = 50
Add '-50' to each side of the equation.
50 + -50 + -20x = 50 + -50
Combine like terms: 50 + -50 = 0
0 + -20x = 50 + -50
-20x = 50 + -50
Combine like terms: 50 + -50 = 0
-20x = 0
Solving
-20x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '-20'.
x = 0.0
Simplifying
x = 0.0
What is the area of the polygon given below?
Look at picture
The answer is B. 525 square units.
The polygon pictured is a composite figure made up of several rectangles. To find the total area, we can find the area of each of the rectangles and sum them together.
From the image we can find the following areas:
Top left rectangle: 9 square units
Top right rectangle: 14 x 3 = 42 square units
Bottom left rectangle: 7 x 14 = 98 square units
Bottom right rectangle: 27 square units
Summing the areas of each rectangle together gives us a total area of 9 + 42 + 98 + 27 = 176 square units.
However the prompt specifies that this is not the total area. There is a small square removed from the bottom left rectangle. We can find the area of this square by subtracting the length of the small rectangle’s missing side (3 units) from the length of the whole rectangle’s side (14 units) and squaring the result. Subtracting 3 from 14 gives us 11 and squaring 11 gives us 121.
So the final area of the polygon is 176 - 121 = 55 square units.
Of the answer choices provided, only 55 square units matches our calculation. So the answer is B. 525 square units.
Heather eats a jelly sandwich every 5th day and drinks milk every 4th day. If she had a jelly sandwich and milk today, how many days will pass before she will have both again?
Follow below steps:
The question is asking to identify how many days will pass before Heather will have both a jelly sandwich and milk again, given that she eats a jelly sandwich every 5th day and drinks milk every 4th day. To find out when Heather will have both on the same day again, we need to find the Least Common Multiple (LCM) of the two numbers, 5 and 4.
The multiples of 5 are 5, 10, 15, 20, 25, and so on. The multiples of 4 are 4, 8, 12, 16, 20, and so on. The first common multiple of both 5 and 4 is 20. Therefore, Heather will have both a jelly sandwich and milk together on every 20th day after today.
So, after today, Heather will wait 19 more days before having both a jelly sandwich and milk on the same day again.

find the value of X
A x= 18
B x=22.5
C x=30
D x=54
First the two angles are equal to one another so take note of that.
Now setup the equation which will be
x+90=4x
Now get rid of alike terms
So subtract x from both sides
90=3x
Now divide 90 by 3
x=30
Answer: The correct option is
(C) x = 30.
Step-by-step explanation: We are given to find the value of x from the figure shown.
From the figure, we note that the angles with measures (x+90)° and 4x° are vertically opposite angles.
Since the measures of two vertically opposite angles are equal, so we must have
[tex](x+90)^\circ=4x^\circ\\\\\Rightarrow x+90=4x\\\\\Rightarrow 4x-x=90\\\\\Rightarrow 3x=90\\\\\Rightarrow x=\dfrac{90}{3}\\\\\Rightarrow x=30.[/tex]
Thus, the required value of x is 30.
Option (C) is CORRECT.

For each pair of polygons, describe the transformation that could be applied to Polygon A to get Polygon B
These are the polygons
The transformation of Polygon A to Polygon B could involve translation, rotation, or reflection. Observe differences in position and orientation between the two polygons to identify the type of transformation.
Explanation:The transformation of a polygon to another can involve a series of moves such as translation (sliding), rotation (turning around a point), or reflection (flipping over a line). By closely comparing the two polyhgons A and B, you can determine which type of transformation has taken place.
For instance, if every point on polygon A has moved in the same direction and distance to form polygon B, a translation has taken place. If polygon B can be obtained by turning polygon A around a point, then a rotation has occurred. If polygon B is a mirror image of polygon A, then it has been reflected.
