What is the sum of the measures of the interior angles of a 20-sided figure?
Enter your answer in the box.
__°
The sum of the measures of the interior angles of a 20-sided figure is 3240.
What are Interior angles ?
An interior angle of a polygon is an angle that is created between two of the polygon's adjacent sides. The interior angle of a polygon is also known as the angle measured at the interior of a polygon.
the number of sides of given polygon is 20.
we know that, sum of the measures of the interior angles can be found by using formula : (n-2) × 180
where n= no. of sides of given polygon
So, sum of the measures of the interior angles of 20 sided figure :
= (n-2) × 180
= (20-2) × 180
= 18 × 180
= 3240 .

4. In one semester, Doug and Laura spent a combined 230 hours in the tutoring lab. If Doug
spent 10 hours less than twice the hours Laura did, how many hours did Doug spend in
the lab?
Answer:
80 hours
Step-by-step explanation:
let d represent doug, let l represent laura
first, set up a system of equations representing the problem:
since doug spent 10 less than twice the hours laura did, and we know that the total amount of hours they spent together is 230:
l=2d+10
d+l=230
then solve:
*first i rearranged the equations so i can solve this system of equations using elimination method*
l-2d=10
l+d=230
*subtract*
3d=240
d=80
so, doug spent 80 hours in the lab

A triangular pen is modeled by △ABC. The vertices of △ABC are A(0, 8), B(12, 3), and C(7, –9). What is the area of the pen?
Answer:
The area of the triangle is 84.511 square units.
Step-by-step explanation:
First step, we need to calculate lengths of line segments AB, BC and AC by Pythagorean Theorem:
AB:
[tex]AB = \sqrt{(12-0)^{2}+(3-8)^{2}}[/tex]
[tex]AB = 13[/tex]
BC:
[tex]BC = \sqrt{(7-12)^{2}+(-9-3)^{2}}[/tex]
[tex]BC = 13[/tex]
AC:
[tex]AC = \sqrt{(7-0)^{2}+(-9-8)^{2}}[/tex]
[tex]AC \approx 18.385[/tex]
Now, we can determine the area of the triangle ([tex]A[/tex]) by Heron's formula:
[tex]A = \sqrt{s\cdot (s-AB)\cdot (s-BC)\cdot (s-AC)}[/tex] (1)
[tex]s = \frac{AB+BC+AC}{2}[/tex] (2)
Where [tex]s[/tex] is the semiperimeter of the triangle.
If we know that [tex]AB = 13[/tex], [tex]BC = 13[/tex] and [tex]AC \approx 18.385[/tex], then the area of the triangle is:
[tex]s = 22.193[/tex]
[tex]A = 84.511[/tex]
The area of the triangle is 84.511 square units.

Element X is a radioactive isotope such that its mass decreases by 67% every year. If
an experiment starts out with 740 grams of Element X, write a function to represent
the mass of the sample after t years, where the daily rate of change can be found
from a constant in the function. Round all coefficients in the function to four decimal
places. Also, determine the percentage rate of change per day, to the nearest
hundredth of a percent.
Answer:
Step-by-step explanation:
X is mass which I s decrease. If you have 740 grams of element x and you add the function.per the rate day you will have a hundredth percent.
Answer:
f(t)=740(0.9970)^365t
0.30% decrease per day

What is Fourteen less than seven times a number is 15
Answer:
29/7 or 4 1/7
Step-by-step explanation:
Let x be the unknown number.
7 times a number is 7x,
and then 14 less than that would be 15.
7x-14=15
Now simplify by adding 14 and dividing by 7
7x=29
x=29/7 or 4 1/7

HelllpFind an equation of a line that contains the points (-3,-1) and (2,-2). Write the equation in slope-intercept form.
Answer:
y = -1/5x -8/5
Step-by-step explanation:
(-3,-1) and (2,-2)
m=(y2-y1)/(x2-x1)
m = ( -2 + 1)/(2 + 3)
m = (-1)/(5)
m = -1/5
y - y1 = m(x - x1)
y + 1 = -1/5(x + 3)
y + 1 = -1/5x -3/5
y = -1/5x -8/5

The 8th grade is holding a fundraiser to raise money for an end of the y ear party. They are selling T-shirts and Caps to raise money. They make $15 profit from each T-shirt and $5 profit from each hat. Their goal is to raise $900.
Part A: Write and equation that represent this situation.
Part B: Find 3 combinations of shirts and caps that will achieve their goal of raising $900.
A CORRECT ANSWER WILL HAVE 4 PARTS!
For each t-shirt sold, which I'll call t, 8th grade makes $15.
For each hat sold, which I'll call h, 8th grades makes $5.
They want to raise $900
A: The equation to represent this situation is 15t+5h=900 because if 8th grade adds up all the profits from both hats and t-shirts, the goal is to make $900, so the total profit from shirts and hats should equal 900 dollars.
B: I'm just going to choose random numbers. Let's say nobody wanted to buy a hat from the 8th graders (h=0). You'd end up with
15t+5(0)=900
15t=900
t=60 - If they sold 0 hats they would have sold 60 shirts to raise $900
Now let's say it was the other way around - nobody wanted to buy t-shirts
15(0)=5h=900
5h=900
h=180 - If they sold 0 t-shirts they'd have to sell 180 hats to raise $900
Finally let's say they sold 30 t-shirts
15(30)+5h=900
450+5h=900
5h=450
h=90 - They'd have to sell 30 t-shirts and 90 hats to raise $900
