Since the sanctuary was established, the estimated population of American robins in the area has increased from 86 to 102.
Describe the percent change in the estimated population of American robins. Round to the nearest whole percent.
Enter your answer in the box to complete the sentence.
Answer:
15.7%
Step-by-step explanation:
102-86=16
(16*100)/102
Solve for x. Round to the nearest tenth, if necessary.
Answer:
[tex]\sqrt19[/tex]
Step-by-step explanation:
First we solve for the biggest triangle: using the Pythagorean theorem, (a^2 + b^2 = c^2) we put in the sides,
9^2 + b^2 = 10^2.
solve, 81 + b^2 = 100
then we subtract 81 from both sides. b^2 = 19, and the answer is [tex]\sqrt 19[/tex].
Now we know what the third side is, which is the hypotenuse for the smaller triangle, so we use the Pythagorean theorem again.
4^2 + x^2 = 19.
Solve
16 + x^2 = 19
Subtract 16 from both sides
x^2 = 19
and finally, we take the square root of both sides
x = [tex]\sqrt19[/tex]

? = 1/7 ÷ 5/7
? = 1/7 × 7/5 = 7/35
?=7/35
? = 1/5

Mathematically, why am i so uneducated?
Answer:
I know this is most likely a joke but I'll answer anyways :)
"Mathematically" you might have poor education whether it's bad teachers, bad school, or maybe you're just not working hard enough. Maybe you are educated and you're just comparing yourself against smarter people which might make you seem not very educated. Or maybe you're secretly a super genius prodigy and you're just too lazy too show it. Who knows...

a store sells laptops for 720 each. this price is 20 percent more than what it cost the store to buy each of them. before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost cost. how much would it cost an employee to purchase one of these laptops at the sale?
Answer:
462
Step-by-step explanation:
720 is 120% of the store price so to find the store price, we can muliply by the reciprical or 5/6.
720*5/6= 600
The employee can purchase the laptop at 23% off this price or at 77%. Multiply the price by 0.77 to get the employee price.
600*0.77 = 462
The total cost of the laptop at which an employee purchase is 482 and this can be determined by using the unitary method.
Given :
A store sells laptops for 720 each. This price is 20 percent more than what it cost the store to buy each of them. Before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost.The following steps can be used in order to determine the total cost of the laptop at which an employee purchase:
Step 1 - The unitary method can be used in order to determine the total cost of the laptop at which an employee purchases.
Step 2 - According to the given data, 720 is the 120% cost at which the store sells. So, the value of the 100% cost is:
[tex]=\dfrac{720}{120}\times 100[/tex]
= 600
Step 3 - Now, the employee can purchase the laptop at a 23% discount that is 77% of the original cost.
Step 4 - So, the total cost of the laptop at which an employee purchase is:
[tex]=\dfrac{77}{100}\times 600[/tex]
= 462

A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . Write an equation for the monthly payment a customer pays according to the new plan . Use y for monthly payment , and x for international minutes.
Type the equation in the form y=ax+b without using any spaces. Write any decimals in the form 0.00
Answer:
y = a(.10) + 25
Step-by-step explanation:
Using the equation y = ax + b.
"$25 per month for unlimited calls in the country and $0.10 per minute for international calls."
The word "per" indicating that you are multiplying this.
The only variables being multiplied are a and x.
Thus, a is the amount of minutes, x is the cost of international calls and b is the cost of unlimited calls.

Could someone show me the streamline for this problem? The answer is 909, but I'd like to know how
1000-100+10-1
Answer:
1000-100=900,900+10=910,910-1=909
Step-by-step explanation:
Hey there!
1,000 - 100 + 10 - 1
1,000 - 100 = 900
= 900 + 10 - 1
900 + 10 = 910
= 910 - 1
= 909
Thus that’s why 1,000 - 100 + 10 - 1 is most likely equal to 909

Remember that you flip the signs whenever you divide an inequality by a negative.
So here we divide both sides by negative four and then scan the signs to get

Write the equation of the line that passes through the points (8,−7) and (−9,7). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
y + 7 = (-14/17)(x - 8)
Step-by-step explanation:
We want the equation of this line in the point-slope form y - k = m(x - h).
We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above. Then the other point is represented by (x, y) in the point slope form shown above:
Let (h, k) be 8, -7) and let (x, y) be (-9, 7). Then, y - k = m(x - h) becomes:
7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17
The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).
Another way to get this result would be to find m in the usual way:
rise 14
m = ------------- = --------- = -14/17 (same as before).
run -17

Find the selling price.
Markup ($) = percent markup (%) x original cost ($)
Selling price ($) = original cost ($) + markup ($)
A local gaming store bought a gaming console for $90. The gaming store sold the console, and the percent markup was 162%. What is the selling price?
The selling price is: $_________
Skip to navigation
Answer:
$145.80
Step-by-step explanation:
The original cost of the product was $90. There was a 162% markup. In order to get the selling price, I like to take away 100 percent and simply add original price+(original price*62%). After taking away 100%, I am left with 62%. I then multiply the original cost ($90) by the remaining percent (62%), getting 55.8. Following the steps that I originally wrote, I now add 90 to 55.8, getting 145.8.

Answer:
40°
Step-by-step explanation:
According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.
So with this, you need to add 70° and 70°.
You get 140°
Then to find the last angle, you will subtract the 140° by 180°.
180°-140° = 40°
Hope this helped! :)
Answer:
40
Step-by-step explanation:
First you add 70 and 70 together to get 140 then minus it by 180.
Then you will get 40 degrees as your answer.
Hope This Helps :)
