Answer:
One
Step-by-step explanation:
Since we have a 90° angle and a 20° angle, the last angle must be 70°.
180° - 90° - 20° = 70°
Now we also have the requirement of a 6-unit side between the 90° and 20° angles.
With all of these requirements, we can only draw one triangle like this since we have an angle, an angle, a required third angle, and a side.
The amount of wheat exported by Canada on average is
approximately 2.21 × 107 tons per year. The amount of
wheat exported by Mexico on average is approximately
8.5 × 105 tons per year. How many times more wheat
does Canada export per year?
Based on the amount of wheat exported by Canada and Mexico, the number of times more wheat exported by Canada over Mexico is 0.26 times.
By how much more than Mexico, does Canada export wheat?This can be found by the formula:
= Amount of wheat exported by Canada / Amount of wheat exported by Mexico
Solving gives:
= (2.21 x 107) / (8.5 x 105)
= 236.47 / 892.5
= 0.26 times

Set the function = 0, factor, and use the zero product property to find the zeros of the function.
f(x) = x2 + 7x - 60
Answer:
-12; 5
Step-by-step explanation:
x^2 + 7x - 60 = 0
D = b^2 - 4ac
D = 7 * 7 + 60 * 4 * 1 = 289
sqrt(D) = sqrt(289) = 17
x₁ = (-b - √D) / 2a = (-7 - 17) / 2 = -24 / 2 = -12
x₂ = (-b + √D) / 2a = (-7 + 17) / 2 = 10 / 2 = 5

The previous triangular prism had a surface area of 288 square units. What happens to the surface area of your prism when you double all four measurements? the surface area doubles. The surface area triples. The surface area increases by 4 times. The surface area increases by 8 times.
Answer:
The surface area increases by 4 times.
Step-by-step explanation:
square root of 288 = 16.970562.... (= 1 side)
1 side(x2) = 33.941125...... (= double of the side)
New area = new side squared
(33.94111....) squared = 1,152 (new area)
1,152/288 = 4
new area is 4 times bigger
288 x4 = 1,152

jessica used 2/3 of her money to but books and 1/6 of her money to buy notebooks. she then had 30$ left in her pocket.How much money did Jessica have i her pocket before shopping?
Answer:
2/3x + 1/6x = 30
x represents her money, because it is unknown
and 30 represents the leftover money she was left, so we solve for x.
x - (2/3x + 1/6x) = 30
Combine multiplied terms into a single fraction.
Find a common denominator;
x - 4/6x - 1/6x = 30
Combine fractions with common denominator.
Multiply all terms by the same value to eliminate fraction denominators;
6x - 4x - 1x / 6 = 30
Cancel multiplied terms that are in the denominator.
x/6 = 30
Multiply them.
*6 *6
To get,
x = 180
Jessica had 180 dollars in her pocket before shopping.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let's assume that Jessica had 'x' dollars in her pocket before going shopping.
Jessica used 2/3 of her money to buy books, which is (2/3)x dollars.
She used 1/6 of her money to buy notebooks, which is (1/6)x dollars.
So, the total amount of money spent on books and notebooks is:
(2/3)x + (1/6)x = (4/6)x + (1/6)x = (5/6)x
Jessica had 30 dollars left in her pocket after shopping. So, we can write:
x - (5/6)x = 30
Simplifying the equation, we get:
(1/6)x = 30
Multiplying both sides by 6, we get:
x = 180
Therefore, Jessica had 180 dollars in her pocket before shopping.

A group of 125 teenagers were asked which of the following activities they would most likely choose to spend their free time doing: reading a book, watching television, playing video games, or listening to music. The results are displayed in the circle graph below.
What is the difference in percent between those who chose reading a book and those who chose to listen to music?
a. 16%
b. 8%
c. 12%
d. 4%
Answer:
12%
Step-by-step explanation:
Read a book = 16%
Listen to music = 28%
We can read the question in different ways:
1. The simple difference between the two is 12%
2. Out of the sample, the two groups include:
15 chose books
35 chose music
Within this sample of 50 teenagers,
(15/50) or 30% chose books, and
(35/50) or 70% chose music
That makes a difference of 40%
I would chose the first interpretation, 12% [Especially since 40% is not an option.]

a manufacturer sells an article to a wholeseller at a profit of 18%,the wholesaler sells it to a retailer at a profit of 20%.the retailer sells it to a customer at a profit of 25%.if the customer pays ₹30.09 for it,find the cost of the manufacturer
Answer:
the cost price of manufacturer = RS. 14.80
Step-by-step explanation:
the retailers profit = profit percent of sold amount
= 25% of 30.09
= 25/100 × 30.09
= 7.5225
here, the cost price of retailer =
sold amount- profit amount
or, CP = 30.09 - 7.5225
= 22.5675
now, profit of whole seller =
profit% of sold amount
or, 20% of SP
20/100 × 22.5675
= 4.5135
CP = SP - Profit
or, CP = 22.5675- 4.5135
CP = 18.054
now, profit of manufacturer = profit℅ of SP
= 18% of 18.054
= 18/100 × 18.054
= 3.24972
or, CP of manufacturer = SP - profit amount
= 18.054 - 3.24974
= 14.80428
Therefore, cost price of manufacturer = 14.80

What happens when the slope decreases? Write 4 sentence's
Answer:
Suppose the slope of a line were to decrease. Then it would get flatter. These conditions are true whether or not the slope was positive or negative to begin with. A higher positive slope means a steeper upward tilt to the line, while a smaller positive slope means a flatter upward tilt to the line.
For a decreasing function, the slope is negative. The output values decrease as the input values increase. A line with a negative slope slants downward from left to right as in (b). If the function is constant, the output values are the same for all input values so the slope is zero.
