Answer:
0.63 or 63/100
Step-by-step explanation:
Answer:
0.63
Step-by-step explanation:
For this you would want to do the reverse operation. So you see that it is multiplication? You would have to do division to get n by itself. When you divide 630 by 1,000 you would get 0.63.

Answer:
$1.50 and 4.5 miles
Step-by-step explanation:
The constant of proportionality is basically just the slope of a line on a graph
Slope can be found by:
[tex]\frac {y_{2} - y_{1}} {x_{2} - x_{1}}[/tex]
10.50 - 7.50 = 3
7 - 5 = 2
3/2 = 1.50 = $1.50

Roberto must make his costume for the school play. He needs a piece of fabric that is 2 and 2/3 yards long and 1 and 1/2 yards wide. What is the area of the piece of fabric Roberto needs?
Answer:
4 yd².
Step-by-step explanation:
From the question given above, the following data were obtained:
Length (L) = 2⅔ yards
Width (W) = 1½ yards
Area (A) =.?
The area of the piece of fabric that Roberto needs can be obtained by using the formula for calculating the area of a rectangle. This is illustrated below:
Area (A) = Length (L) × Width (W)
A = 2⅔ × 1½
A = 8/3 × 3/2
A = 8 × ½
A = 4 yd²
Thus, the area of the piece of fabric that Roberto needs is 4 yd²

Answer:
(1, -2) Option A in your list of possible answers
See attached image.
Step-by-step explanation:
We need to graph the lines by using a couple of points on the plane for each equation.
For example:
the points (0, -3) and (3, 0) for the line y = x - 3
and the points (0, 1) and (-1, 4) for the line y = - 3 x + 1
Please see the lines in the attached image, and notice that they intersect at the point (1, -2), which gives you the solution for the system.

what positive whole number can you multiply by 3 and add1,or multiply by 2 and add 8?
Answer:
7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.
Step-by-step explanation:
Multiplying the positive whole number 7 by 3 and adding 1 will get:
(7 × 3) + 1 = 21 + 1 = 22
Multiplying the positive whole number 7 by 2 and adding 8 will get:
(7 × 2) + 8 = 14 + 8 = 22
Therefore, 7 is the positive whole number which we can multiply by 3 and add 1, or multiply by 2 and add 8; and it will give the same answer.

what is the height of the cone if a metal sphere of radius 4m is melted to form a cone of base 5m?
9514 1404 393
Answer:
10.24 m
Step-by-step explanation:
The volume formulas for the figures are ...
V = 4/3πr³ . . . sphereV = 1/3πr²h . . . coneYou can fill in the given radii and set the volumes equal:
4/3π(4 m)³ = 1/3π(5 m)²h
h = (4^4)/(5^2) m . . . . . divide by the coefficient of h
h = 10.24 m
The height of the cone is 10.24 meters.
Errol bought a skateboard helmet on sale at 40% off. The original price was $49.95. What is the amount of discount?
Answer:
[tex]Discount = \$19.98[/tex]
Step-by-step explanation:
Given
[tex]Amount = \$49.95[/tex]
[tex]Price\ Off = 40\%[/tex]
Required
Determine the discount
The discount is calculated by multiplying the price off by the original price:
[tex]Discount = Amount * Price\ Off[/tex]
[tex]Discount = \$49.95 * 40\%[/tex]
Convert % to decimal
[tex]Discount = \$49.95 * 0.40[/tex]
[tex]Discount = \$19.98[/tex]
Hence, the amount of discount is $19.98
Kimberly's family has a dinner bill of $26 and wants to leave a 15% tip for their server. How much tip are they leaving?
A.3.90
B.$4
C.$29.90
D.$39
Answer:
uuummm i need this answer too actually
Step-by-step explanation:
Answer:
A.$3.90
Step-by-step explanation:
So we have $26 and the tip is 15%, so we just find 15% of $26A percentage is a number divided by 100, so 15% is the fraction [tex]\frac{15}{100}[/tex] Now what fraction of 26 is [tex]\frac{15}{100}[/tex] ? We multiply and seeSo [tex]\frac{15}{100}*26=\frac{15*26}{100}=\frac{390}{100}=3.90[/tex] so $3.90 is 15% 0f $26 Then $3.90 is the amount of the tipThe graph of g is a vertical shrink by a factor of 1/3 and a reflection in the y-axis, followed by a translation 3 units right of the graph of f(x)=x2. Write a rule for g.
Answer: g(x) = (1/3)*(-x)^2 + 3.
Step-by-step explanation:
Let's define all the transformations in a general way,
A vertical contraction/dilation of a scale factor a is written as:
g(x) = a*f(x)
where if a > 1, it is a dilation.
if 0 < a < 1, it is a contraction.
A reflection in the y-axis changes the value of the x-component and leaves the y-component invariable, then this transformation is written as:
g(x) = f(-x).
A translation of A units up (A positive) is written as:
g(x) = f(x) + A.
Then for this case we have:
A dilation with scale factor 1/3.
g(x) = (1/3)*f(x)
A reflection over the y-axis.
g(x) = (1/3)*f(-x)
A translation of 3 units up.
g(x) = (1/3)*f(-x) + 3
(in that order, remember that the order in which you applly the transformations matters)
Then g(x) = (1/3)*f(-x) + 3
and f(x) = x^2, so we can replace that in the equation for g(x)
g(x) = (1/3)*(-x)^2 + 3.
Transformation involves changing the position of a function.
The rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]
The parent function is given as:
[tex]\mathbf{f(x) = x^2}[/tex]
The rule of vertical shrink by a factor of 1/3 is:
[tex]\mathbf{(x,y) \to (x,\frac 13y)}[/tex]
So, we have:
[tex]\mathbf{f'(x) = \frac 13x^2}[/tex]
The rule of reflection across the y-axis is:
[tex]\mathbf{(x,y) \to (-x,y)}[/tex]
So, we have:
[tex]\mathbf{f''(x) = \frac 13(-x)^2}[/tex]
[tex]\mathbf{f''(x) = \frac 13x^2}[/tex]
The rule of translation 3 units right is:
[tex]\mathbf{(x,y) \to (x - 3,y)}[/tex]
So, we have:
[tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]
Hence, the rule for g is: [tex]\mathbf{g(x) = \frac 13(x - 3)^2}[/tex]

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let's assume that there are x students in each class.
Since there are two classes, the total number of students is 2x.
Now,
Since every student wrote 4 letters.
The total number of letters written = 4 x the number of students.
200 = 4 x (2x)
200 = 8x
x = 200/8
x = 25

There are 25 students in each class.
