Cole hauls heavy equipment from North Dakota to Winnipeg. After crossing into Canada, he sees a sign that says the weight limit for the road is 7 metric tons. He must decide whether to drive on this road or to take a detour. How many U.S. standard tons are allowed on the road?
Work Shown:
1 metric ton = 1.1023 US tons
7*(1 metric ton) = 7*(1.1023 US tons)
7 metric tons = 7.7161 US tons

What is the area of one of the blue half circles? HINT: Remember, Area = pi x radius squared.
So you will need to use the 40 (this is the diameter so make sure you find the radius). Then
since you only want a half circle, you will need to divide it by 2. SHOW ALL WORK!
Answer:
Depends on how the teacher wants the answer:
400π (in terms of pi) or 1256.6 (rounded to tenths place)
Step-by-step explanation:
40/2 = 20, the radius of one of the blue circles
Use the formula: πr², but divide it by 2 because it is a semicircle
π20² = 400π = 1256.63706
Let me know if you need help rounding it if the question asks you to.

The newspaper in Haventown had a circulation of 80,000 papers in the year 2000. In 2010, the circulation was 50,000. With x=0 representing the year 2000, the graph below models this scenario.
What number will complete the point-slope equation that models this scenario?

The slope of the given equation is -3000.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
We are aware that the Havertown newspaper had 80,000 readers in the year 2000 (when x=0) and 50,000 readers in the year 2010 (when x=10). With this knowledge, we can determine the slope of the line that depicts this situation:
slope = (change in y) / (change in x) = (50,000 - 80,000) / (10 - 0) = -3,000
So the slope of the line is -3,000.
We also have a point on the line: (10, 50,000). Using the point-slope form of the equation of a line, we can write:
y - 50,000 = -3,000(x - 10)
Now we just need to find the value that goes in the blank to complete the equation.
Because the line's slope is -3,000, y reduces by 3,000 for every unit increase in x.
We can see that a one-unit increase in x corresponds to a one-year increase in the time since x indicates the number of years from the year 2000. As a result, we might conclude that 3,000 fewer copies of the newspaper were distributed annually.
The point-slope equation is complete when:
y - 50,000 = -3,000(x - 10)
So the answer is -3,000.

Cranberry juice costs $6.30 per quart and apple juice costs $3.60 per quart. Terrence wants to know how many quarts q of cranberry juice he should mix with 4 quarts of apple juice to make cranberry-apple juice. He also wants to sell the juice at cost for $4.50 per quart. Which equation below represents the situation?
A. 3.60(q – 4) + 25.20 = 4.50q
B. 3.60q + 25.20 = 4.50(q + 4)
C. 6.30(q – 4) + 14.40 = 4.50q
D. 6.30q + 14.40 = 4.50(q + 4)
Answer:
The correct answer is D
Step-by-step explanation:
Cost of q quarts of Cranberry juice will be: $ 6.30q and cost of 4 quarts of apple juice will be $ (3.60×4)= $ 14.40. Total quarts of items would be q+4 , and he also wants to sell the juice at cost for $4.50 per quart. That means that the total cost to sell the juices will be $4.50(q+4) . Also, Total cost= Cost of q quarts of cranberry juice+cost of 4 quarts of apple juice.

Denise drew a diagram of part of a slide at a community playground.The slides ladder forms two angles with the ground.The measurement of one angle is half the measurement of the other.What are the measures of the angle show your work.
Applying the concept of supplementary angles, their measures are of 60º and 120º.
What are supplementary angles?Two angles are called supplementary if the sum of their measures is of 180º.
In this problem, we have that the measurement of one angle is half the measurement of the other, and they are supplementary, hence:
[tex]x + \frac{x}{2} = 180[/tex]
[tex]\frac{3x}{2} = 180[/tex]
3x = 360
x = 120
x/2 = 120/2 = 60º.
The measures of the supplementary angles are of 60º and 120º.

Find N' after N(2, 3) was reflected over the line y = x + 2.
Answer:
Step-by-step explanation:
Did u find the answer?
The reflected over the line y=x+2 is A''(-3,-2). Each point of the original figure (the pre-image) has an image that is the same distance from the reflection line as the original point, but is on the other side of the line.
What is meant by reflected over the line?Each point of the original figure (the pre-image) has an image that is the same distance from the reflection line as the original point, but is on the other side of the line. This transformation is known as a reflection over line.
A transformational process turns a figure into a reflection. Figures can be reflected in a point, a line, or a plane. When reflecting a figure in a line or a point, the image and preimage coincide. A reflection converts each point of a figure from a point to an image across a fixed line.
From the additional image, you can see that the coordinates of image point A' are after reflection point A about the line y=-x (-3,2).
Next, the coordinates of reflection point A' about the x-axis are (-3,-2).
The complete question is : Find the image of A (-2,3) reflected in the line y= -x and then in the x axis

From 1990 to 2000, the population of California can be modeled by P = 29, 816,591(1.0128) where t is the
number of years since 1990.
A. What was the population in 1990?
B. What is the growth factor?
C. What is the annual percent increase?
D. Estimate the population in 2007.
The population is modeled with an exponential equation, and using what we know about exponential equations we will see that:
A) P(0) = 29,816,591B) the growth factor is 1.0128C) 1.28%D) P(17) = 37,013,551.9How to identify the parts of the exponential equation?
Here we have the exponential equation:
P(t) = 29,816,591*(1.0128)^t
A) The population in 1990 will be given by P(0), this is:
P(0) = 29,816,591*(1.0128)^0 = 29,816,591
B) For an exponential:
A*(b)^x
We can rewrite it as:
A*(1 + r)^x
In this case, b is the growth factor, so in our function, the growth factor is 1.0128
C) Using the above notation, the percent increase by year is given by 100% times r, so first let's get the value of r.
r = b - 1 = 1.0128 - 1 = 0.0128
Then the percent increase is: 0.0128*100% = 1.28%
D) The year 2007 comes 17 years after 1990, so we need to evaluate the equation in t = 17, we will get:
P(17) = 29,816,591*(1.0128)^17 = 37,013,551.9
