whats the formula for the surface area of a triangle?
Answer:
use the formula A = 1/2bh, where A = area, b = base, and h = height. Once you have the areas of all sides and faces, you simply add them together to get the surface area.
Hope this helps!

Pls help I am super confused and pls do not answer if u either cant see, or just dont care. This is serious
Will mark brainliest!
Answer:
h + c = 3 and 4h + 4c =10
No solutions
Step-by-step explanation:
If hot dogs = h, and chips = c,
Then the first scenerio can be written as h + c = 3
The second scenerio is 4h + 4c = 10.
So, your system should be
h + c = 3 and 4h + 4c =10
Solve this system
First, solve c + h = 3 for c.
Subtract h on both sides.
c = -h + 3
Then, substitute c = -h + 3 into the second equation (4c + 4h = 10)
4(-h + 3) + 4h = 10
Simplify.
- 4h + 12 + 4h = 10
12 = 10
This is not right, so this system has no solutions. This means that there is no set cost for the chips or hot dogs (or for both).
Hope this helps! Feel free to ask any questions

2 1/4 ⋅ 1 2/3
as a mixed number
Answer:
[tex]3\frac{3}{4}[/tex]
Step-by-step explanation:
We have two mixed numbers and are asked to multiply them together.
2 1/4 * 1 2/3
First we convert the mixed numbers into improper fractions to make it easier for us. So follow the MA rule.
Multiply the whole number by the denominator and add the numerator.
2 1/4 * 1 2/3
9/4 * 5/3
Now multiply across,
[tex]\frac{9*5}{4*3}[/tex]
[tex]\frac{45}{12}[/tex]
Now we need to convert this back into a mixed number.
So how many times does 45 go into 12?
3 times, and 3 are left.
[tex]3\frac{3}{4}[/tex]
Simplify given fraction into mixed fraction is 3³/₄
Give that:
[tex]2\frac{1}{4} \times 1\frac{2}{3}[/tex]
Find:
Simplify given fraction into mixed fraction

The populations of two different cities are modeled by the equations shown below. The population (in thousands) is represented by y and the number of years since 1970 is represented by x. What year(s) did the cities have the same population? What was the population of both cities during the year(s) of equal population? Answers: (year 1995, 425000 people) and (year 2022, 1910000 people)
Baskinville: y = x2 – 22x + 350
Cryersport: y = 55x – 95
I NEED THE EXPLANATION OF HOW TO GET TO THE ANSWER PLEASE
Answer: hope this helps love.
Step-by-step explanation:
years of equal population are 1995 and 2022.
in 1995, population was 425,000 people and in 2022, population was 1,910,000 people.
Step-by-step explanation: Baskinville: y = x2 - 22x + 350
Cryersport: y = 55x - 950
Note that x2 is xsquare not x2
Resolving the quadratic equations carefully will give the values of y and x which represent the population and years.

Step-by-step explanation:
A roller coaster starts by ascending 15 feet for every 75 feet it moves forward. The
coaster starts at a point 30 feet above the ground. Write the equation of the line that
the roller coaster travels along in point-slope form, and use it to determine the height of
the coaster after traveling 500 feet forward. Assume that the roller coaster travels in a
straight line for the first 500 feet.

Answer:
B
Step-by-step explanation:
Write the equation of the line in fully simplified slope-intercept form.
Answer:
y=-1/2x-1
Step-by-step explanation:
the slope intercept form is y=mx+b
m=slope
b=y intercept (where the line crosses the y axis)
to find slope you do rise over run or rise/run
the rise of you slope is -1, and the run of your slope is 2, meaning your slope is -1/2
the line crosses the y axis at point -1
plug what you find into the slope intercept form, and you get y=-1/2x-1
Explain how to get the answer please.
Two points defining a linear function are shown in the table below.
[tex]\left[\begin{array}{ccc}&x&y\\&-14&-18\\&-10&-12\end{array}\right][/tex]
How do u get the slope?
Slope in fraction form = 3/2
Slope in decimal form = 1.5
============================================================
Explanation:
That table shows the two points (x1,y1) = (-14,-18) and (x2,y2) = (-10,-12).
Each row is a different point.
To find the slope, we subtract the y values to get y2-y1 = -12-(-18) = -12+18 = 6
Then we subtract the x values to get x2-x1 = -10-(-14) = -10+14 = 4
Lastly, we divide the two differences: ydiff/xdiff = 6/4 = 3/2
The slope in fraction form is 3/2, which is equivalent to the decimal form 1.5
------------------------
If you want, you can apply the slope formula like so
m = slope
m = rise/run
m = (change in y)/(change in x)
m = (y2-y1)/(x2-x1)
m = (-12-(-18))/(-10-(-14))
m = (-12+18)/(-10+14)
m = 6/4
m = 3/2
m = 1.5
We effectively are following the same as steps as before, but in this format, it's more of what you might have on your homework if you were to show the step-by-step process. You could also do a visual graph approach as a different option. Often in math there are multiple ways to get the answer.

There are 15 violinists in the orchestra this year. Next year, two violinists will leave and some new violinists will join the orchestra. If v is the number of violinists who will join the orchestra, which expression(s) represent the number of violinists in the orchestra next year.
A 15−2+v15 minus 2 plus v
B 15−v15 minus v
C v−2v minus 2
D 13+v13 plus v
E v−15v minus 15
F v+13
Answer:
A and D
Step-by-step explanation:
There are already 15. Take away 2 in the next year and also add some (v) in the same year.
13 + v is the simplified version of the original expression (15 - 2 + v)
