The amount of wheat exported in Canada is 2.6 x 10 tons per year.
What is standard form?Standard form is used to transform large numbers into smaller number. In order to write a number in standard form, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
For example: the number 1 x 10² is equivalent to 100
How many times large is the wheat exported from Canada?2.21 x 10^7 ÷ 8.5 x 10^5 = 0.26 x 10^2 = 2.6 x 10

b. How would you model your equation on a number line to show your answer?
Real-world situations can be modeled with equations and represented on a real number line. In this exercise, positive
ten represents the $10 given as a birthday gift because it is a gain. Negative four represents the $4 spent on snacks
because it is a loss. Gaining $10 and then taking away $4 leaves you with $6.

Kareem rented a truck for one day. There was a base fee of $19.99 , and there was an additional charge of 83 cents for each mile driven. Kareem had to pay $135.36 when he returned the truck. For how many miles did he drive the truck?
139 miles
explanation:
$1 → 100 cents
Here the base fee is fixed.
make equation:
$19.99 + 0.83m ↣ $135.36
0.83m ↣ $135.36 - $19.99
0.83m ↣ $115.37
m ↣ 139
Therefore she has ridden 139 miles.

The dimensions of this figure are changed so that the new surface area is exactly 12 what it was originally.
What is the new surface area?
Enter your answer as a decimal in the box.
yd²
Complex solid composed of rectangular prisms in an L shape. The height of the taller side of the L shape is labeled 8.4 yd. The height of the shorter side of the L shape is labeled 3.8 yd. The width of the of the shorter section of the L shape is labeled 4.3 yd. The length of the taller section of the L shape is labeled 10.1 yd and the width is labeled 2 yd.
The surface of the figure is the amount of space on the figure
The new surface area would be half of the original figure
How to determine the surface area?The question is incomplete, so I will give a general explanation.
Assume the surface area of the original figure is A.
Then the area of the new figure would be:
A2 = A * k
Where k is the scale of dilation.
From the question, we have:
k = 1/2
So, the equation becomes
A2 = A * 1/2
This gives
A2 = 1/2A
The above means that the new surface area would be half of the original figure

Zucchini weights are approximately normally distributed with mean 08 pound and standard deviation 0.25 pound. Which of the following shaded regions best represents the probability that a
randomly selected zucchini will weigh between 0 55 pound and 13 pounds?
Answer:
The correct option is A
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 0.8 \ pounds[/tex]
The standard deviation is [tex]\sigma = 0.25 \ pounds[/tex]
Generally the the probability that a randomly selected zucchini will weigh between 0 55 pound and 13 pounds is mathematically represented as
[tex]P(0.55 < X < 1.3) = P(\frac{0.55 - 0.8}{ 0.25} < \frac{X - \mu}{\sigma } < \frac{1.3 - 0.8}{0.25})[/tex]
=> [tex]P(0.55 < X < 1.3) = P( -1 < Z < 2 )[/tex]
So looking the option of normal curves given in the question we see that it is option A that matches our interval

What is a Quadratic Equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. The fact that the coefficient of x² is a non-zero term (a 0) is a necessary need for an equation to be a quadratic equation.
As per the given data:
f(x) = 9m² + 3m - 2
To find the x-intercept of this function:
The roots of f(x) will be the x-intercepts of the given function.
f(x) = 9m² + 3m - 2
9m² + 3m - 2 = 0
9m² - 3m + 6m - 2 = 0
3m(3m - 1) + 2(3m - 1) = 0
(3m + 2)(3m - 1) = 0
The roots are m = -(2/3) and m = (1/3)
Hence, the x-intercepts are -(2/3) and (1/3).
The correct options are (B) and (C)

Hector purchased a brand new 2019 BMW 760.
The cost of the vehicle was $97,899.99. There is a
25% discount for cash customers, Hector paid
cash. The sales tax rate for the vehicle was 3.75%.
What was the total price of the purchases
(SHOW ALL WORK)
(PLEASE HELP)
Answer:
Step 1: Calculate percentage discount
=> $97,899.99 × 25/100
=> 97,899.99/1 × 25/100
{multiply the numerator by the numerator and the denominators by the denominators}
=> 2,447,499.75/100
divide 24,474.9975 by 100
=> 24,474.9975
=> 24,474.9975
{Substract 24,474.9975 from 97,899.99.}
=> 97,899.99 - .24,474.9975
=> 73,424.9925
Step 2: Calculate sales tax rate
Sales tax rate = price × rate/100
=> 73,424.9925 × 3.75/100
=> 275,343.7/100
=> 2,753.437
Add to 73,424.9925
=> 73,424.9925 + 2,753.437
=> 76,178.4295
=> 76,178.4 { Rounded to 1 dp)
Therefore, the total price of the purchases is 76,178.4295

5. Which graph represents a function?
Answer:
bottom left, the one that looks like a v
Step-by-step explanation:
You can test if something is a function by looking to see if there is a place where an x has 2 ys. if there are 2 ys for an x it is not a function.
Answer:
bottom left
Step-by-step explanation:
Bottom right is not a function because you would get an infinite number of results. It does not exactly map one output of this function.
The top two graphs are incorrect because they have more than 1 output. You can do the Vertical Line test and see that the top two graphs do have more that one output.
In order for it to be a function it has to have one output.

Answer:
-1
Step-by-step explanation:
Gradient is another word for slope, and slope can be defined as rise/run.
From the point (0,0) to (1,-1), it moved one unit down and one unit to the right. The slope for this line can be represented as -1/1, which is equal to -1.
Therefore, the gradient of the graph shown is -1.

In a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b, what is the value of b, if
a=2sqrt3 , c=2b ?
Answer: b = √6
Step-by-step explanation: Use the Pythagorean Theorem to solve this.
a² + b² = c²
Plug in your values:
2√3² + b² = 2b²
When a square root is squared, the square root is cancelled out so you will be left with this:
2(3) + b² = 2b²
Subtract b² from both sides so you’re left with:
6 = b²
Now, to get rid of the square, just square root both sides:
√6 = √b²
Since the √6 is not a perfect square, leave it in the radical. Then, you get your answer:
b = √6
Answer:
the answer:b is equivalent to 2

The graph of y= ax^2 + c contains the point (2,14). Which point lies on the graph of y=a(x-2)^2 + c?
Answer:
(4, 14)
Step-by-step explanation:
We are given;
Graph of: y = ax² + c
That it contains point (2, 14)
Now,we want to find which point lies on the graph: y = a(x - 2)² + c.
Now, symbol "a" means the value of horizontal shift because the constants are grouped with x.
If the value of "a" is greater than 0,then it means that the graph shifted to the left by "a" units while if the value of "a" is less than 0,it means the graph shifted to the right by "a" units.
Now, from the 2 graph equations given, and from the principle of graph shifts, we can say that the first graph has shift by 2 units to the right because "a" equals -2.
What this implies is that every point on the graph y = ax² + c shifts by 2 units right.
Thus, the points that lie on the graph y = a(x - 2)² + c are: (x + 2, y)
Thus, points are: (2 + 2, 14) = (4, 14)
