Answer:
x = 19
Step-by-step explanation:
(4x - 4) and (6x - 6) are a linear pair and sum to 180° , that is
4x - 4 + 6x - 6 = 180
10x - 10 = 180 ( add 10 to both sides )
10x = 190 ( divide both sides by 10 )
x = 19
how do I find b with the equation y=0.023x + b using the points (0, 11.08) and (1,11.06)
To find b in the equation y = 0.023x + b, you have to replace with a given point into the equation. For example, point (0, 11.08) means x = 0 when y = 11.08, replacing into the formula:
11.08 = 0.023*0 + b
11.08 = b

The following scatterplot represents the number of negative consumer reviews for a given model of cell phone and the total number of that same cell phone model that were sold. Is it reasonable to predict that if there are 75 negative reviews the number of cell phones sold of that same model will be close to 850,000? Why or why not
According to the plotted line, we can see that for 75 negative reviews, an approximate number of phones sold is 600,000, that is not close to 850,000. Therefore, it is not reasonable to predict that if there are 75 negative reviews, the number of cell phones sold will be close to 850,000
Determine the intervals where the function f(x)=x^3-6x^2 is increasing and decreasing. Also determine the local maximum and minimum values for the function. Sketch a graph of the function showing these maximum and minimum points on your graph.
For the function f(x) = x³ - 6x², we have that:
The function is increasing on these following intervals: (-∞, 0) U (4, ∞).The function is decreasing on the interval (0,4).The local maximum value for the function is at point (0,0).The local minimum value for the function is at point (-4,32).When a function is increasing and when it is decreasing, looking at it's graph?Considering the graph of the function, it is increasing when it is "moving northeast", that is, to the right and up on the graph, meaning that when x increases, y increases.Then, it is decreasing when it is "moving southeast", that is, to the right and down the graph, meaning that when x increases, y decreases.In the context of this function, we have that it is increasing to the left of x = 0 and to the right of x = 4, hence the interval is given by:
(-∞, 0) U (4, ∞).
On the remaining interval, that is, (0,4), the function is decreasing.
The critical points are given as follows:
At x = 0, the function changes from increasing to decreasing, hence there is a local maximum at point (0,0).At x = 4, the function changes from decreasing to increasing, hence there is a local minimum at point (4,32).More can be learned about functions at https://brainly.com/question/24808124

A student argued that a pizza cut into 12 pieces was more than a pizza cut into 6 pieces. How would you respond?
I would respond with a vehement disagreement because using the division operation, the more the divisor, the less the quotient.
What is a division operation?A division operation is one of the four basic mathematical operations.
The division operation breaks a number or object into many parts. The number to be divided is known as the dividend.
The dividing number or parts are called the divisor while the quotient is the result of the division operation.
For instance, when 144 is divided by 12, the result is 12. When the same number is divided by 6, the result is 24. From this, we can determine the division operation that yields more value.
Thus, a pizza cut into 12 pieces does not yield more than a pizza cut into (divided) 6 pieces.

A tractor trailer contains a cab for the driver and the trailer for the cargo. Suppose the weight of the cab is 7,600 pounds, and the weight of the trailer is 10,800 pounds. The trailer is carrying palettes for a shipment where each palette is 1,200 pounds. What is the total weight of the tractor trailer when there are 31 palettes in the trailer?
The total weight of the trailer is 55,600 pounds including the cab, trailer and the palettes
Weight of the cab = 7600 pounds
Weight of the trailer = 10,800 pounds
Weight of each palette carried by trailer = 1200 pounds
Weight: Weight is the result of multiplying the mass by the acceleration that is acting on it. Usually, it's the mass of the object times the acceleration brought on by gravity.
So, total weight of 31 palettes = 1200*31 = 37200 pounds
Total weight of the tractor = Weight of the cab + Weight of the trailer + Weight of 31 palettes
= 7600 + 10,800 + 37,200
= 55,600 pounds
So, total weight = 55,600

In this example, the rapper wants to divide a recipe in half to make a cake for 5 people instead of 10. Explain why he multiplies the first ingredient, ⅔ of a cup sugar, by ½.
The rapper multiplies the first ingredient, ⅔ of a cup of sugar, by ½ because as he wants to get the cups of sugar required for five people instead of ten, he can use the inverse of division, which is multiplication.
What is multiplication?Multiplication is one of the mathematical operations.
Multiplication uses the multiplicand and multiplier to compute the product, which is also described as the result of the multiplication operation.
The quantity of sugar required for 10 = ⅔
The quantity of sugar required for 5 = ⅔ ÷ 2
⅔ ÷ 2 = ⅔ x ½
= ¹/₃
Thus, by multiplying ⅔ by ½, the rapper gets the cups of sugar required for 5 people instead of 10 as ¹/₃ cups through the division inverse.

Step 1
At 1:30 pm
Monument's shadow= 22.5 feet
Calvin's shadow =3.5 feet
Calvin is 6.25 feet tall
a) for the monument
shadow= adjacent side=22.5 ft
hypotenuse= unknow=h1
height of the monument = opposite side= y1
b) for Calvin
shadow= adjacent side=3.5 ft
hypotenuse= unknow=h2
height of the Calvin = opposite side= 6.25

What are the missing values?Ratio is a concept that is used in mathematics to compare two or more numbers together. It shows the relationship between two or more numbers. Increase in the value of numbers that ratios to each other increase at a proportional rate.
The first step is to determine the amount of cream that is needed for 1 coffee = 3/8 ÷ 4
= 3/8 x 1/4 = 3/32
Amount of cream needed for 8 coffees = 3/32 x 8 = 3/4
Amount of cream needed for 16 coffees = 3/32 x 16 = 1 1/2
Now determine how much coffee is needed for 1 ounces of cream
4 ÷ 3/8

The annual percentage yield (APY) for a savings account that earned $56 in interest on $800 over 365 days is 7%.
The APY (annual percentage yield) is calculated using the formula:
(Interest / Principal)x100
By plugging in the values for interest and principal, we can determine the APY.
Given that,
Principal amount: $800
Interest earned: $56
Time period: 365 days
To calculate the annual percentage yield (APY),
Use the formula:
APY = (Interest / Principal)x100
In this case,
The interest earned = $56
The principal (initial amount) = $800.
Plugging these values into the formula:
APY = (56 / 800)x100
= 0.07x100
= 7%
Hence,
The annual percentage yield for this savings account is 7%.
