13. It takes Seymore, a slimy slug, 20 minutes to travel from his favorite bush to the local trash can (a distance of 30 meters), how far can he travel in 1 hour (60 minutes)?
Answer:
90 meters
Step-by-step explanation:
From the question we are to calculate the distance that the slug can move in 60 minutes.
From the question, we know that:
20 minutes = 30 meters
60 minutes = x meters
Cross Multiply
20 minutes × x meters = 30 meters × 60 minutes
x meters = 30 meters × 60 minutes/20 minutes
x meters = 90 meters
A student stands at the entrance of her school and notes the colors of cars that enter the parking lot. The results are shown in the bar graph below.
which of the following is a true statement regarding the info in the bar graph?
a. car color is a discrete variable
b. car color is a catagorial variable
c. car color is a continuous variable
d. frequency is a discrete variable
thank ya so much and have a lovely day!!
Answer:
B
Step-by-step explanation:
Color of car is a categorical variable. its value are not numerical
The frequency of cars entering the parking lot is a discrete variable so option (d) will be correct.
What is a variable?A variable in mathematics is a representation of any quantity whose value is changeable.
For example speed of a vehicle is a variable.
The value of the variable changes but the meaning of the variable never for example speed of vehicle changes but the word speed does not change.
A discrete variable is a variable whose values are different.
Since car color is not a variable because the meaning of variable is not constant in car color.
The frequency of vars is a discrete variable because it is different for each kind of car.
Hence "The frequency of cars entering the parking lot is a discrete variable".

Write the equation of the line in slope-intercept form that has: slope: -1 and point: (1, 1)
Answer:
f(x) = -1x + 1
Step-by-step explanation:
f(x) = mx + b
the equation above is slope intercept form. in order to make it you need a slope and a y intercept. you were given the slope, so now you need a y intercept. but where would you find that??? look no farther than the point you were given, (1,1). the y intercept is the second number in the parentheses. next you take your slope and your y-intercept and place them in.

1.5(x +4) - 3 = 4.5 (x - 2)
Answer:
Step-by-step explanation:
x-4
Answer:
x = 4
Step-by-step explanation:
1.5(x + 4) - 3 = 4.5(x - 2)
Distribute;
1.5x + 6 - 3 = 4.5x - 9
Collect like terms;
1.5x + 3 = 4.5x - 9
Subtract 1.5x from both sides;
3 = 3x - 9
Add 9 to both sides;
12 = 3x
Divide both sides by 3;
x = 4

Find the value of x in the image
Answer:
50
Step-by-step explanation:
a pentagon has a total of 540 degrees
105, 115, 110, 180-2x, 180-3x are the interior angles (subtract each from 180 because they're on lines)
540= 105+115+110+(180-2x)+(180-3x)
540=330 +(180-2x)+(180-3x)
210=360-5x
-150=-5x
50=x

What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
/ Division operation: Divides left-hand operand by right-hand operand
For example 12/2 = 6
To determine missing values in the magic squares,
Apply the arithmetic operations in the rows and columns,
The sum of each row = 9
The sum of each column = 9
The sum of each diagonal = 9
Here the first grid :

PLEASE HELP IM DESPERATE! Which of these is equivalent to the expression s + s + s + s +12 ? ANSWER CHOICES: A. 4s + 3, B. 4(s + 3), C. 4s (s + 3), D. 4 + s + 12
Answer:
B
Step-by-step explanation:
s+s+s+s+12 = 20. s=2
4(s+3)
4(2+3)
4(5)=20
Hey there!
s + s + s + s + 12
= 1s + 1s + 1s + 1s + 12
= 2s + 2s + 12
= 4s + 12
So, we’re looking for something that’s equivalent to: 4s + 12
• Option A.
4s + 3 ≠ 4s + 12
Option A. is wrong because it is NOT equivalent to the given equation
• Option B.
4(s + 3)
= 4(s) + 4(3)
= 4s + 12
Thus, this mean Option B. could possibly be your answer.
• Option C.
4s(s + 3)
= 4s(s) + 4s(3)
= 4s(s) + 3(4s)
= 4s^2 + 12s
Option C. is wrong because it is NOT equivalent to the given equation as well.
• Option D.
4 + s + 12
COMBINE the LIKE TERMS
= 16 + s
= s + 16
Option D. is wrong because it isn’t equivalent to the given equation as well.
Therefore, your answer is:
Option B. 4(s + 3)

Answer:
3
Step-by-step explanation:
If you substitute the values x = 0 and y = −5 into the second equation, you get a false statement: 2(−5) − 10 = 2(0). To solve this system, try rewriting the first equation as x = 2y − 8. Then substitute 2y − 8 in for x in the second equation, and solve for y. The correct answer is x = −2, y = 3.

how do i find a slope?
Answer:
The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.
