A ladybug and ant move at constant speeds. The diagrams with tick marks show their positions at different times. Each tick mark represents 1 centimeter.
In your textbook pg. 111, scale the vertical and horizontal axes by labeling each grid line with a number. You will need to use the time and distance information in the tick-mark diagrams.
Which line shows the ladybugs movement? The ant?
Unit rate for the Ladybug? The ant?
How long does it take for the ladybug to travel 12 cm? The ant?
Answer:
From the graph we can say that ant is moving faster than the ladybug
Slope of the ant's movement will be steeper than the ladybug
Hence, line "v" denotes the speed of ant and line "u" denotes the speed of ladybug.Unit rate/slope of the graph is (distance traveled/elapsed time)
Unit rate of ant is 3/2 cm/sec and that of ladybug is 1 cm/sec.Ant takes (12×2/3) = 8 sec and ladybug takes (12×1) = 12 sec to travel 12 cm.Remember ant will take less time to travel a certain distance than ladybug.
Sarah is solving r - 7 = 234. She wants to use inverse operations to solve this equations. Therefore she should,
a. multiply 7 to both sides of the equation
b. divide 7 to both sides of the equation
c. add 7 to both sides of the equation
d. subtract 7 to both sides of the equation.
Answer:
Option C : add 7 to both sides of the equation is the correct answer.
Step-by-step explanation:
Given that:
Sarah is solving the following equation.
r - 7 = 234
Sarah wants to use inverse operations.
In inverse operation she will eliminate 7 from left side of the equation by adding 7 to the both sides of the equation.
Hence,
Option C : add 7 to both sides of the equation is the correct answer.

The population standard deviation for the height of college basketball players is 2.9 inches. If we want to estimate a 99% confidence interval for the population mean height of these players with a 0.45 margin of error, how many randomly selected players must be surveyed
Answer:
276
Step-by-step explanation:
Given :
Standard deviation (σ) = 2.9 inches
Error margin (E) = 0.45
Confidence interval = 99%
Using the relation to obtain the sample size (n)
n = [(Zcrit * σ) / E]²
Zcritical at 99% confidence interval = 2.576
n = [(2.576 * 2.9) / 0.45]²
n = [7.4704 / 0.45]²
n = 16.600888^2
n = 275.58951
n = 276 samples
Sample size
Hilary has 48 building blocks in the red bucket. That is 6 times as many blocks in the green bucket. How many building blocks are in the green bucket?
Answer: 8
Step-by-step explanation:
From the question, we are informed that Hilary has 48 building blocks in the red bucket which is 6 times as many blocks in the green bucket.
Let the number of building blocks that are in the green bucket be represented by x.
Based on the scenario given in the question, this will be:
6 × x = 48.
6x = 48
x = 48/6.
x = 8
This means that there are 8 green building blocks
What is the value of x
Group of answer choices
60 degrees
30 degrees
15 degrees
45 degrees
Answer:
x = 15 degrees
Step-by-step explanation:
This is a right angle, since we know that a right angle contains 90 degrees, we can form an equation.
[tex]30+4x=90[/tex]
Now, we solve for x.
[tex]-30+30+ 4x = -30+90[/tex]
[tex]4x=60[/tex]
[tex]\frac{4x}{4}=\frac{90}{4}[/tex]
[tex]x=15[/tex]

Math question below
Answer : The surface area of triangular prism is 1080 in².
Step-by-step explanation :
Formula used to calculate the surface area of triangular prism is:
Surface area of triangular prism = (2 × Area of triangle) + Area of all rectangle
Area of triangle = [tex]\frac{1}{2}\times base\times height[/tex]
Area of rectangle = length × breadth
In the given triangular prism, there are 2 triangles and 3 different rectangles.
Surface area of triangular prism = [tex](2\times \frac{1}{2}\times base\times height)[/tex] + Area of rectangle ABCF + Area of rectangle ABDE + Area of rectangle CDEF
Surface area of triangular prism = [tex](2\times \frac{1}{2}\times 10\times 24)+(24\times 14)+(26\times 14)+(14\times 10)[/tex]
Surface area of triangular prism = 1080 in²
Therefore, the surface area of triangular prism is 1080 in².
8 over 15? is it closer to 0, 1 over 2 or 1
Answer:
its closer to 1....
Step-by-step explanation:
1/2 is half
so...
half of 15 is 7.5
8 is larger than 7.5
so that makes it closer to one
6/9 of 27 students in a class play soccer some of the students play offense and the rest play defense the ratio of the students playing offense to the total number of students playing soccer is 1 to3 how many students play defense
12 students play defense. 1st step. 6/9 of 27 is 18. 2nd. the ratio of the students playing offense to the total number of students playing soccer is 1 to 3 which means the total amount of students is '3', in the ratio it's 3 because it's simplified (i like to think of it as 'groups'). since we know that there are a total of 18 students and there's 3 total 'groups' we divide 18 into 3 which is 6. so there's 6 students in each group. we subtract 6 (1 group) from 18 ( the total number of students) which is 12, so there are 12 students playing defense. if you wrote the ratio again without simplifying it would be 6:18

-5(3-x)+4=5x-11
Answer:
Let's solve your equation step-by-step.
−5(3−x)+4=5x−11
Step 1: Simplify both sides of the equation.
−5(3−x)+4=5x−11
(−5)(3)+(−5)(−x)+4=5x+−11(Distribute)
−15+5x+4=5x+−11
(5x)+(−15+4)=5x−11(Combine Like Terms)
5x+−11=5x−11
5x−11=5x−11
Step 2: Subtract 5x from both sides.
5x−11−5x=5x−11−5x
−11=−11
Step 3: Add 11 to both sides.
−11+11=−11+11
0=0
Solve: 8 - 3x > -25 please
Answer:
x < 11
Step-by-step explanation:
8 - 3x > -25
Subtract 8 from each side
8 - 3x-8 > -25-8
-3x> -33
Divide each side by -3, remembering to flip the inequality
-3x/-3 < -33/-3
x < 11

PLEASE HELP ME I WILL MARK BRAINLIEST IF YOUR RIGHT..
Answer:
C
Step-by-step explanation:
a function means each x value will have only one outcome
example, (8,5) (9,5) is ok but (8,6) (8,10) isnt
Answer: The correct answer is "C" because (x, y) represent a function of ordered pairs like {(-1, 1), (0, 0), (1, 1), (2, 2)}. :)

Translate this verbal expression to an algebraic expression.
Two times the sum of x and 10.
A 2(x - 10)
B 2x + 10
C 2(x + 10)
D 2 + x + 10
Answer:
C.
Step-by-step explanation:
It's c because you need the sum of x and 10 but both multiplied by 2. So it wouldn't be A nor B because they are both subtracting. That would leave you with C and D and d doesn't have anything to do with multiplying. I dunno made sense to me.
