Sammy opens a bag of
skittles and counts all the
green skittles. There are
13 green skittles in a bag
with 65 skittles. What is the
ratio of green to total
skittles?
Answers
13/65
1/5
Decimal 0.2
Final answer:
To find the ratio of green to total skittles, divide the number of green skittles by the total number of skittles and simplify the fraction. The ratio of green to total skittles is 1:5.
Explanation:
To find the ratio of green to total skittles, we need to divide the number of green skittles by the total number of skittles and simplify the fraction.
Ratio = Number of green skittles / Total number of skittles
Ratio = 13 / 65
Since 13 and 65 are both divisible by 13, we can simplify the fraction to:
Ratio = 1 / 5
Therefore, the ratio of green to total skittles is 1:5.

Which method is best used to prove that a figure has a right angle?
a) Using slope formula to show two segments have opposite reciprocal slopes.
Ub Using slope formula to show two segments have the same slope.
C) Using distance formula to show two segments are congruent.
od) Using the midpoint formula to show two segments have the same midpoint.
Answers
Answer:
A
Step-by-step explanation:
Right angle means that the two sides that meet to create right angle are "perpendicular".
Two perpendicular lines meet to form the angle of 90 degrees.
In coordinate geometry, how do we prove that two lines are perpendicular??
We show that their slopes are negative reciprocals of each other.
This also tells us that the angle between the two lines are "right angle".
So, we can use slope formula to show two segments have opposite reciprocal slopes, that will tell us that it is a right angle between the two segments.
Option A is right.

Write an equation in slope intercept form for the line that has a slope of 12 and passes through the point (3,20)
Answers
Answer:
y= 12x-16
Step-by-step explanation:
Given that you have a slope of 12 and a point of (3, 20), you are most obligated to using the Slope-Intercept form, or y=mx+b.
What this allows you to find is the y-intercept if your line has one. You take your point, (3,20), and you insert the values at the appropriate places. You should now have 20=12(3)+b. You will then solve for b by multiplying 12 and 3 to get 36 and subtract that from both sides of the equal sign. You should have 20-36=b. 20-36 is -16, which is your y-intercept.
Now you know all your needed values, you would write the Slope-Intercept form without the values for y and x, to represent your equation.
Since 12 is your slope, it will be 'm' and -16 will be 'b'.
You will end with y = 12x - 16.
Given:
Line passing through,
[tex](x_1,y_1) = (3, 20)[/tex]Slope,
[tex]m = 12[/tex]The equation will be:
→ [tex]y - y_1 = m(x-x_1)[/tex]
By substituting the values,
→ [tex]y-20=12(x-3)[/tex]
→ [tex]y-20=12x-36[/tex]
[tex]y = 12x-16[/tex]
Thus the above answer is right.

Michelle opened a savings account for her emergency fund. She deposited $2000 into her account, which earns 2.10% interest, compounded monthly. How much will she have in the account after one year?
Answers
Michelle will have $28200 in account after one year.
Step-by-step explanation:
Given ,
P ( Principle amount )= $2000
r ( rate of interest)= 2.10% per month
n (number of times rate of interest is applied) = 12
t ( time period ) = 1 years
Compound Interest = P ( 1 + r/n ) * n*t
⇒ [tex]2000 (1+2.10/12) * 12*1[/tex]
⇒ [tex]2000*12*1.175[/tex]

Kate bought $23.40 worth of two types of bird seed. Thistle bird seed sells for $1.60 per pound
and wild bird seed sells for $0.95 per pound. If she bought 12 pounds of wild bird seed, write
and solve a linear equation to find the amount of thistle bird seed she purchased
Answers
Answer:
The amount of thistle bird seed she purchased was 7.5 pounds
Step-by-step explanation:
Let
x ----> the amount in pounds of thistle bird seed she purchased
x ----> the amount in pounds of wild bird seed she purchased
we know that
Kate bought $23.40 worth of two types of bird seed.
so
[tex]1.60x+0.95y=23.40[/tex] ----> equation A
She bought 12 pounds of wild bird seed
so
[tex]y=12\ pounds[/tex]
substitute the value of y in the equation A
[tex]1.60x+0.95(12)=23.40[/tex]
solve for x
[tex]1.60x=23.40-11.40\\1.60x=12\\x=7.5\ pounds[/tex]
therefore
The amount of thistle bird seed she purchased was 7.5 pounds
Kate bought 7.5 pounds of thistle bird seed.
Since Kate bought $ 23.40 worth of two types of bird seed, thistle bird seed sells for $ 1.60 per pound and wild bird seed sells for $ 0.95 per pound, if she bought 12 pounds of wild bird seed, to find the amount of thistle bird seed she purchased, the following calculation must be performed, through a linear function:
(12 x 0.95) + 1.60X = 23.40 11.40 + 1.60X = 23.40 1.60X = 23.4 - 11.4 X = 12 / 1.60 X = 7.5
Therefore, Kate bought 7.5 pounds of thistle bird seed.

y = 4/3x - 12
Step-by-step explanation:
Use Point Slope Form: (y - y1) = m(x - x1)
Step 1: Find the slope
m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
m = [tex]\frac{-4 - (-8)}{6 - 3}[/tex]
m = [tex]\frac{-4 + 8}{3}[/tex]
m = [tex]\frac{4}{3}[/tex]
Step 2: Plug into point slope form
(y - (-4)) = 4/3(x - 6)
y + 4 = 4/3x - 24/3
y + 4 - 4 = 4/3x - 8 - 4
y = 4/3x - 12
Answer: y = 4/3x - 12

Step-by-step explanation:
A store that sells merchandise on a college campus is restocking their inventory of sweatshirts and t-shirts. They order a total of 934 items. Each sweatshirt costs $8.00 and each t-shirt costs $5.00. They spend a total of $5,933.00.
A system of equations is written to represent this scenario, where s represents the number of sweatshirts ordered and t represents the number of t-shirts ordered.
{s+t=934
{8s+5+=5933
The solution to the system is (421, 513). Interpret this solution in the context of the situation.
A. The store ordered 513 sweatshirts and 421 t-shirts.
B. The store ordered 421 sweatshirts and 513 t-shirts.
C. The store spent $513.00 on sweatshirts and $421.00 on t-shirts.
D. The store spent $421.00 on sweatshirts and $513.00 on t-shirts.
Answers
Answer:
Option B.
Step-by-step explanation:
A system of equations is written to represent this scenario, where s represents the number of sweatshirts ordered and t represents the number of t-shirts ordered.
s + t = 934
8s + 5t = 5,933
The solution to the system is (421, 513).
So, The number of sweatshirts = 421
And the number of t-shirts = 513
Because 8 * 421 + 5 * 513 = $5,933
We will check the options:
A. The store ordered 513 sweatshirts and 421 t-shirts. ⇒Wrong
B. The store ordered 421 sweatshirts and 513 t-shirts. ⇒True
C. The store spent $513.00 on sweatshirts and $421.00 on t-shirts. ⇒Wrong
Because the solution represents the number of sweatshirts and t-shirts.
D. The store spent $421.00 on sweatshirts and $513.00 on t-shirts. ⇒Wrong
Because the solution represents the number of sweatshirts and t-shirts.
So, the answer is option B.
how can you find the differnt between points
Answers
Answer:
subtract one from the other
Step-by-step explanation:
You find the difference between points the same way you find any difference: you subtract one from the other.
Points are generally described by an ordered pair. When you subtract one point from the other, you subtract corresponding parts of the ordered pair:
(a, b) - (c, d) = (a-c, b-d)
__
Sometimes, when you're interested in finding the difference between points (x, y), you want to do something different with the y-difference than you do with the x-difference.
For example, the slope of a line is calculated as the ratio of the y-difference to the x-difference. The length of a line segment is the root of the sum of the squares of the differences.

Sarah and Kaylee go to the movie theater and purchase refreshments for their friends.
Sarah spends a total of $47.00 on 12 drinks and 1 bag of popcorn.
Kaylee spends a total of $81.75 on 3 drinks and 9 bags of popcorn.
Write a system of equations that can be used to find the price of one drink and the price of one bag of popcorn.
Using these equations, determine and state the price of a drink, to the nearest cent.
Answers
Each drink costs $3.25 and each popcorn costs $8.
Step-by-step explanation:
Step 1:
Assume each drink costs x dollars and each popcorn costs y dollars.
From the given data, we can write the following equations;
[tex]12x + y = 47[/tex], take this as equation 1,
[tex]3x+9y=81.75[/tex], take this as equation 2.
Step 2:
We multiply equation 2 with 4 so we can cancel out the variable x in both equations. By doing this we get
[tex]3x+9y = 81.75[/tex], take this as equation 3. When we subtract 3 from 1, the x variable is canceled out and y can be calculated.
[tex]-35y = -280, y = \frac{280}{35} = 8[/tex]
Step 3:
Substituting this value of y in any of the previous equations we will get x's value.
Here this value of y is substituted in equation 1.
[tex]12x+8 = 47, 12x= 39[/tex],
[tex]x=\frac{39}{12} = 3.25[/tex]
So we have x = $3.25 and y = $8. So each drink costs $3.25 and each popcorn costs $8.
