isaiah wrote this problem in his notebook. Using the Vocabulary boxes,label the parts of the division problem. then, using the vocabulary, explain how isaiah can check whether his quotient is correct. quotient, divisor, dividend
Answer:
9 is divisor, 648 is dividend and 72 is the quotient.
Isaiah can check his work by multiplying divisor(9) and quotient (648). If quotient is correct the product will be equal to dividend.
Step-by-step explanation:
Consider the provided information.
A number by which another number is to be divided is called divisor.
A number which is divided by another number is called dividend.
A result obtained by dividing one number by another is called quotient.
Here 9 is the number which divide 648.
Therefore, 9 is divisor.
648 is the number which is divided by 9.
Therefore, 648 is dividend.
The result obtained by dividing 648 by 9 is 72.
Therefore, 72 is the quotient.
Isaiah can check his work by multiplying divisor(9) and quotient (648). If quotient is correct the product will be equal to dividend.

Final answer:
The equation solved for w is B. w = lh/v
Explanation:
1. Understand the Formula:
The formula for the volume (V) of a rectangular prism is V = lwh, where l is the length, w is the width, and h is the height.2. Isolate w:
To solve for w, isolate w on one side of the equation.Divide both sides of the formula by lh: V/lh = w3. Determine the Correct Equation:
Compare the isolated w with the provided answer choices.The correct equation solved for w is w = lh/vTherefore, the correct answer will be B. w=lh/v

Which graph represents the solution set of the system of inequalities?
{ y < -3x - 2
{ y ≤ x - 2
The common shaded region of the given inequality is given by figure 3 with yellow color.
What is an inequality and how to graph it ?An inequality is a statement that compares two expressions we can solve an inequality by adding same number to both sides or by subtracting same number from both side.
To graph the inequality
Replace the sign of the inequality with equal to sign.Graph the equation made with equal to line.If the point (x, y) satisfies the inequality then check whether the inequality is satisfied on that point or not.Shade the region on that side of line where any point satisfies the equation if not shade the opposite side of region.if the sign of inequality is < ,> with equal to gin then make the line dotted for respective equality otherwise a solid line.Given inequalities are :
y < -3x -2
y ≤ x-2
For y < -3x-2 consider the equality y = -3x -2
Put x =0 ⇒ y = -2 , ( 0, -2)
Put y = 0 , x = -2/3, ( -2/3 , 0)
∴ y = -3x -2 is the line passing through the points ( 0, -2) and ( -2/3 , 0)
⇒ Put (0,0) in y<-3x-2 ⇒ 0 < -3(0) -2 ⇒0 < -2 which is false
Therefore , the inequality y<-3x-2 is the shaded region shown in figure 1
Similarly for inequality y ≤ x - 2 , Consider y = x - 2
Put x = 0 ⇒ y =-2, (0,-2)
Put y=0 ⇒ x =2 , (2,0), thus y = x - 2 is the line passing through (2,0) and (0,-2)
Put (0,0) in y ≤ x - 2⇒ 0 ≤ -2 , which is false
therefore the region of this inequality is as shown in figure 2.
The common shaded area is given by yellow color figure 3 .

A) The slope is positive 3 and the y-intercept is (0,4).
B) The slope is negative 3 and the y-intercept is (0,4).
C) The slope is positive 3 and the y-intercept is (0,-4).
D) The slope is negative 3 and the y-intercept is (0,-4).
The correct choice that supports the graph that Heather has drawn is:
The slope is positive 3 and the y-intercept is (0, 4).
Option A is the correct answer.
We have,
To determine which choice supports the graph that Heather has drawn for the equation 3x - y = -4, we need to consider the slope and y-intercept.
The equation is in the form y = mx + b, where m represents the slope and b represents the y-intercept.
Comparing the given equation to the standard form, we can rearrange it as y = 3x + 4.
From this, we can determine that the slope is positive 3 and the y-intercept is (0, 4).
Therefore,
The correct choice that supports the graph that Heather has drawn is:
The slope is positive 3 and the y-intercept is (0, 4).

Ling uses 21 bananas to make 7 fruit smoothies. What is the unit rate that Ling uses for bananas per each smoothie? What is the unit rate? Explain how to use equivalent fractions to find the answer
Answer:
The unit rate that ling uses for bananas per each smoothie is (3/1) bananas per smoothie
Step-by-step explanation:
Ling uses 21 bananas to make 7 fruit smoothies. Total of bananas B = 21. Total of smoothies S =7.
The unit rate U is the relationships B divided by S.
U = B/S
U = 21 bananas / 7 smoothies
U = 21/7 Bananas per smoothies.
We can use the equivalent fractions to find the unit rate. 21 can be expressed as 7*3. 7 can be expressed as 7*1. We can simplify the number 7 in numerator and denominator.
U = (7*3)/(7*1)
U = 3/1.
Finally, the unit rate is 3/1 bananas per smoothie.

She wrote identity instead of commutative in Step 2.
She wrote commutative instead of distributive in Step 4.
She wrote identity instead of associative in Step 2.
She wrote commutative instead of associative in Step 4.
In her work, Maya misidentified the associative property as the identity property in step 2 and the commutative property in step 4.
Explanation:The question pertains to the simplification of the given expression: (5.2 − 4.5) − 5.5 + 4.8. The error lies in Maya's interpretation of the mathematical properties used in the simplification process. In Step 2, she has referred to the rearrangement of minus signs as the result of the 'identity property'. However, this should be the 'associative property' which allows the grouping of numbers to be changed. In Step 4, she refers to her re-ordering of the addition and subtraction as the 'commutative property'. However, it should be 'associative property' as it allows changing of grouping but the order within groups must be maintained.

A film set designer is using white and colored tiles in a pattern to create paths of different lengths. If x is the length of the path in feet, the number of colored tiles needed to make it is calculated using the rule
(4x2y3)(3x2y2)
where y represents the number of white tiles.
Which simplified expression represents the number of colored tiles used for a path of length x feet?
7x4y5
7x4y6
12x4y5
12x4y6
The simplified algebraic expression for the number of colored tiles used for a path(4x^2y^3)(3x^2y^2), is 12x^4y^5. Hence the correct option is 3,
Given the algebraic rule for determining the number of colored tiles ((4x2y3)(3x2y2)), we simplify this expression by multiplying the coefficients and then by adding the exponents for x and y (since they are the same base).
Multiply the coefficients: 4 x 3 = 12
Add the exponents for x: 2 + 2 = 4 (since x2 x x2 = x2+2)
Add the exponents for y: 3 + 2 = 5 (since y3 x y2 = y3+2)
A sales representative earns a 2.5% commission on sales. Find the commission earned when the total sales are $80,700.
To find the commission earned by a sales representative, multiply the total sales by the commission rate of 2.5%. For total sales of $80,700, the commission earned would be $2,017.50.
Explanation:To find the commission earned by a sales representative, we need to multiply the total sales by the commission rate.
In this case, the total sales are $80,700 and the commission rate is 2.5%.
So, the commission earned can be calculated as:
$80,700 x 0.025 = $2,017.50
Therefore, the sales representative will earn a commission of $2,017.50.
Balu and Pumba shared ½ of a cake. Balu got to eat twice as much cake as Pumba. What fraction of the whole cake did Balu eat?
Answer:
Balu ate [tex]\frac{1}{3}[/tex]fraction of the whole cake
Step-by-step explanation:
Let x be the amount of cake eaten by Pumba
Balu got to eat twice as much cake as Pumba.
Balu eat cake = 2x
Balu and Pumba shared ½ of a cake.
So, [tex]2x+x=\frac{1}{2}[/tex]
[tex]3x=\frac{1}{2}[/tex]
[tex]x=\frac{1}{6}[/tex]
So, Pumba's share = [tex]\frac{1}{6}[/tex]
Balu's share = 2x = [tex]\frac{2}{6}=\frac{1}{3}[/tex]
Hence Balu ate [tex]\frac{1}{3}[/tex]fraction of the whole cake
