Brenna writes a product of six negative factors. She uses the following steps to determine that the product of the six numbers will be positive. Step 3 is missing. Group the factors into pairs. The numbers in each pair have the same sign. _____________________________________ The product of three positive numbers is positive. Therefore, the product of the original six factors is positive. What is step 3? A. The product of two numbers with the same sign is positive. B. The product of two numbers with different signs is negative. C. The factors in a product can be grouped in any way without changing the value of the product. D. The factors in a product can be written in any order without changing the value of the product.
Answer: (A)
Step-by-step explanation:
The product of two numbers with the same sign is positive.
Since the numbers in each pair have the same sign, the product will be positive.

The length of a rectangle is three times its width the length is 3 3/4 feet. What is the area if the rectangle?
Answer:
A = 4 11/16 or 4.6875
Step-by-step explanation:
3 3/4 = 3W
divide both sides by 3
15/4 divided by 3 = W
15/4 x 1/3 = W
5/4 = W
A = L x W
3 3/4 x 1 1/4 = 15/4 x 5/4 = 75/16 = 4 11/16
A customer requires a car service for 80 miles,
How much money will the customer save by taking Sal's Car Rides instead of Ray's Limo? Enter the answer in the box.
Answer:
$25
Step-by-step explanation:
Derive an equation to represent the cost of using each ride.
Sal's Car Rides:
Using 2 pairs of values from the table, (0, 40) and (20, 80), find the slope, m (fee per mile).
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{80 - 40}{20 - 0} = \frac{40}{20} = 2 [/tex]
The y-intercept, b, is the one-time fee for fuel. This is the value of the cost ($) when number of miles traveled is 0.
Thus, b = 40.
Substitute m = 2, and b = 40 into [tex] y = mx + b [/tex].
Equation for the total cost for Sal's Car Rides would be:
[tex] y = 2x + 40 [/tex].
Find the total cost to be charged if a customer requires the a car service for 80 miles if he chooses Sal's Car Rides.
Simply substitute x = 80 in [tex] y = 2x + 40 [/tex].
[tex] y = 2(80) + 40 = 200 [/tex]
The customer would pay $200.
Ray's Limo:
The equation that represents the total cost (y) to be charged for number of miles (x), given that $2.50 is charged per mile plus a one-time fee of $25 for fuel, would be:
[tex] y = 2.5x + 25 [/tex].
If a customer uses Ray's Limo services for 80 miles, the cost charged would be:
Substitute x = 80 in [tex] y = 2.5x + 25 [/tex].
Thus:
[tex] y = 2.5(80) + 25 = 225 [/tex].
The fee the customer would pay = $225 for using Ray's Limo services.
Therefore, if the customer takes Sal's Car Rides instead of Ray's Limo, he would save, $225 - $200 = $25.
The customer would save $25.

1.Wayne raked 30 bags of leaves in 3 hours. If he raked the same number of bags each hour, how many bags of leaves did he rake in one hour?
2.Mr. Ordonez gives his math students 34 quizzes during 17 weeks of school. If he gave the same number of quizzes each week, how many quizzes does Mr. Ordonez give his students every week?
3. Mrs. Sapanaro $245 for her and 6 people to take a day-long guided tour of the Everglades. How much does the guided tour cost per person?
Answer:
1. You would divide 30 by 3 which would be 10 bags of leaves per hour.
2. You would divide 34 by 17 which would be 2 quizzes per week.
3. You would have 7 people because it says Mrs. Sapanaro and the other 6. So you divide 245 by 7 which is 35$ per person.
❆ Answer:
1. 10 bags per hour
2. 2 quizzes
3. 35 dollars per person
❆ Step-by-step explanation:
1 - divide. 30 ÷ 3 = 10
2 - divide. 34 ÷ 17 = 2
3 - divide. 245 ÷ 7 = 35

Rectangle ABCD is dilated with center at (0, 0) and scale factor 2. Select the three statements that are true about the dilation.
Answer:
Options (3), (4) and (6)
Step-by-step explanation:
Coordinates of the vertices of the given rectangle are,
A(1, 5), B(3, 2), C(-3, -2) and D(-5, 1)
When rectangle ABCD is dilated by a scale factor of 2 about the origin,
Rule to be followed for the dilation,
(x, y) → (2x, 2y)
Therefore, image of the rectangle ABCD will be,
A(1, 5) → A'(2, 10)
B(3, 2) → B'(6, 4)
C(-3, -2) → C'(-6, -4)
D(-5, 1) → D'(-10, 2)
- Hence point B' is located at (6, 4).
- Rectangle ABCD and A'B'C'D' are similar as all the angles of image will be same as the pre-image after rigid transformation (dilation).
- Let the equation of the line B'C' is,
y = mx + b
Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{4-2}{6-3}[/tex]
= [tex]\frac{2}{3}[/tex]
Since B'C' will pass through origin, y-intercept will be zero.
Therefore, equation of B'C' will be,
y = [tex]\frac{2}{3}x[/tex]
Options (3), (4) and (6) are the correct options.

In two or more complete sentences explain how to balance the chemical equation and classify its reaction type. ___NaI + ___Pb(SO4)2 ⟶ ___PbI4 + ___Na2SO4
Answer:
4112
Step-by-step explanation:
Answer:
By applying law of conservation of mass.
Explanation:
Every balanced chemical equation follows law of conservation of mass.
This law states that mass can neither be created nor can be destroyed but it can only be transformed from one form to another form.
This law also states that the total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.
For the given reaction, the balanced chemical equation follows:
4Na1+Pb(SO4)__Pb14+2Na2SO4
On reactant side:
Number of sodium atoms = 4
Number of iodine atoms = 4
Number of lead atoms = 1
Number of sulfur atoms = 2
Number of oxygen atoms = 8
On product side:
Number of sodium atoms = 4
Number of iodine atoms = 4
Number of lead atoms = 1
Number of sulfur atoms = 2
Number of oxygen atoms = 8
Hence, the balanced chemical equation is written above.

The deli in front of the school sells 36 cheese sandwiches a day, which was 40% of the total number of sandwiches sold that day. What was the total number of sandwiches sold that day?
Answer:
The total number of sandwiches sold that day was 90.
Step-by-step explanation:
Given that the 36 cheese sandwiches sold represent 40% of the total sandwiches sold on that day, to obtain the total number of sandwiches sold the following calculation must be made:
40 = 36
100 = X
((100 x 36) / 40) = X
3600/40 = X
90 = X
Therefore, the total number of sandwiches sold that day was 90.

Answer:
32%
Step-by-step explanation:
136/200 broke. We want to know how many eggs out of 100 broke, so we need to set up an equivalent proportion.
136/200=x/100
Cross multiply.
13600=200x
Divide both sides by 200.
68=x
Since 68 percent broke, that means the other 32 percent survived.

n − 2/3 = 25 3/4 help now
Answer:
26 5/12
Step-by-step explanation:
n − 2/3 = 25 3/4 Add 2/3 to both sides
n - 2/3 + 2/3 = 25 3/4 + 2/3 Combine
n = 25 3/4 + 2/3
Work with the fractions
3/4 + 2/3 The lowest common denominator is 12
(3*3)/(3*4) = 9 / 12
(2*4)/(3*4) = 8/ 12
9/12 + 8/12 = 17/12 = 1 5/12
Now you need to add 1 to 25
1 + 25 = 26
And add the fraction 5/12
The answer is 26 5/12
