Answer:
A )Mass -47.9 g
A) Explanation: Based on the given conditions, formulate: x + 2 ×58.35 = 68.8
Calculate the product or quotient: x + 116.7 = 68.8
Rearrange unknown terms to the left side of the equation: x = 68.8 - 116.7
Calculate the sum or difference: x = - 47.9
get the result:x = - 47.9
Answer: x = - 47.9

A deck of Uno cards has 4 colors (suits): Red, Yellow, Green, Blue
Each color has cards numbered 1 to 9,
so the total number of these cards = 49 = 36
(An Uno deck also has other, special cards, but for this question, those special cards are removed for the
deck. Only the numbered cards are used.)
a) Event E = Randomly selecting an UNO card that is Red.
What is the probability of event E?
(Enter a fraction; it does not have to be reduced.)
b) Event F = Randomly selecting an Uno card that is some number from 1 to 6 of any of the 4 colors.
What is the probability of event F?
(Enter a fraction; it does not have to be reduced.)
c) How many cards are in the intersection of events E and F?
d) P(E and F) = the probability of choosing a card in the intersection of events E and F: P(E and F) = ?
e) Let event G = E or F.Use the General Addition Rule to compute P(G): P(G) = P(E) + P(F) - P(E and F)
f) How many cards are in event G?

Erica solved the equation −5x − 25 = 78; her work is shown below. Identify the error and where it was made.
−5x − 25 = 78
Step 1: −5x − 25 − 25 = 78 − 25
Step 2: −5x = 53
Step 3: negative five times x over negative five = fifty-three over negative five
Step 4: x = negative fifty-three over five
Step 1: She should have added 25 to each side.
Step 1: She should have divided both sides by −5.
Step 3: She should have divided both sides by −5.
Step 3: She should have multiplied both sides by −5.

The length of a side of a square in inches is approximately 5.29 inches.
What is Square?A square is a four sided polygon where each side are equal and each angle equal to 90 degrees.
The formula to find the area of a square is,
Area of a square = a²,
where "a" is the side length of the square.
Given, area of the square = 28 square inches.
Let "a" be the side length of the square.
a² = 28
a = √28 inches ≈ 5.29 inches.
Hence the length of a side is 5.29 inches.

Write a proportion you can use to solve.
Answers
1. The relationship between number of towers and number of customers is proportional.
2. When there are 576 towers, the number of customers that the company is 27648 customers.
How to calculate the value?From the information, the table shows the number of cell phone towers a company will build as the number of its customers increases.
When there are 5.25 towers, the customers are 252. This will be:.
= 252 / 5.25
= 48
Also, when it's 6.25, the customers are 300. This will be:
= 300/6.25
= 48
Therefore, there's a constant value of 48. This illustrates proportionality.
When there are 576 towers, the number of customers that the company have will be:
= 576 × 48
= 27648

Answer:
m = 21
Step-by-step explanation:
-5 = 2 - [tex]\frac{m}{3}[/tex]
Multiply both sides of the equation by 3.
-15 = 6 - m
Swap sides so that all variable terms are on the left hand side.
6 - m = -15
Subtract 6 from both sides.
-m = -15 - 6
Subtract 6 from −15 to get −21.
-m = -21
Multiply both sides by −1.
m = 21

Divide 2y2 + 8 by 2y + 4. Which expression represents the quotient and remainder?
y – 2 –
y + 2 –
y + 2 +
y – 2 +
Answers
When 2(y^2) + 8 is divided by 2y + 4 is equal to (y - 2) + (16 / (2y + 4)). The expression represents the quotient is the 2y + 4. While the expression represent the remainder is 16 / (2y + 4). The remainder of the given expression can also be solve using the remainder theorem.
Answer:
We need to perform division of 2y2 + 8 by 2y + 4. To solve this problem, we need to use the long method of division such as shown below:
y - 2 r. 16
-----------------------
2y+4 √2y2 + 0y + 8
- (2y2 + 4y)
-----------------------
0y2 - 4y + 8
- (-4y -8)
-----------------------
0y + 16
The answer is y-2 + (16/(2y+4)) on which the remainder is 16 / (2y+4).

Which of following is the graph of y = -(x + 1)2 -3? o ty 2 ?? 덕 a -2 2 4 n DONE
Answers
Answer:
Neither of the graphs shown.
Step-by-step explanation:
Given the quadratic equation, y = - (x + 1)² - 3, where a = -1, and the vertex is the minimum value that occurs at point (-1, -3). It is easier to tell which graph corresponds to the given equation due to the coefficient, a. In quadratic fucntions, if a < 0, then it means that it is a downward-facing parabola. The value of a makes the parent function wider or narrower.
Also, the parabola is shifted 1 unit to the left, as defined by h = -1, and 3 units downward, defined by k = -3.
I'm not sure if there are other graphs as options. Since neither one of the graphs shown applies to the given quadratic equation, I'm including a screenshot of the correct graph for your reference, where it shows where the vertex is located, along with the y-intercept, (0, -4) -- just in case.

Nathaniel is deciding between two parking garages. Garage A charges an initial fee of $8 to park plus $6 per hour. Garage B charges an initial fee of $11 to park plus $5 per hour. Let AA represent the amount Garage A would charge if Nathaniel parks for tt hours, and let BB represent the amount Garage B would charge if Nathaniel parks for tt hours. Write an equation for each situation, in terms of t,t, and determine the hours parked, t,t, that would make the cost of each garage the same.
Answers
Answer:
tt = 3 would make the cost of each garage the same.
Step-by-step explanation:
Garage A: $8 + $6(h)
AA = $8 + $6(tt)
Garage B: $11 + $5(h)
BB = $11 + $5(tt)
If AA = BB
then,
$8 + $6(tt) = $11 + $5(tt)
($6-$5)(tt) = $11 - $8
$1(tt) = $3
tt = 3

what is the slope of the line whose equation is 13x+y-5=0?
Answers
Answer:
-13
Step-by-step explanation:
1. To find the slope, it'd be much to convert the line from standard form to slope-intercept form, meaning we have to solve for y. (y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.)
2. (Solving)
Step 1: Subtract 13x from both sides.
[tex]13x + y - 5 - 13x = 0 - 13x[/tex] [tex]y - 5 = -13x[/tex]Step 2: Add 5 to both sides.
[tex]y - 5 + 5 = -13x + 5[/tex] [tex]y = -13x + 5[/tex]3. As you can see, -13 is in the place of m, the slope.
Therefore, the slope of the equation 13x + y - 5 = 0 is -13.
