There are 13 rungs on the ladder :)
Answer:
23 rungs
Step-by-step explanation:
Let the number of rungs on the ladder be h and make the necessary adjustments based on this
Given that she is on the middle rung of a ladder this is equivalent to
= (h + 1)/2
She climbed up three rungs
= (h + 1)/2 + 3
moved down five rungs
= (h + 1)/2 + 3 - 5
and then climbed up 7 rungs
= (h + 1)/2 + 3 - 5 + 7
Then she climbed up the remaining 6 rungs to the top of the ladder
(h + 1)/2 + 3 - 5 + 7 + 6 = h
(h + 1)/2 + 11 = h
h + 1 + 22 = 2h
2h - h = 23
h = 23

what number will divide into 90 and 100 with no remainder
10 is your answer
Divide 10 from both numbers
90/10 = 9 (no remainder)
100/10 = 10 (no remainder)
~Rise Above the Ordinary
Final answer:
The number that will divide into 90 and 100 with no remainder is 10.
Explanation:
To find a number that will divide into 90 and 100 with no remainder, we need to find the greatest common divisor (GCD) of 90 and 100.
One way to do this is by listing all the factors of both numbers and identifying the largest number that divides evenly into both.
The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.
The largest number that divides evenly into both 90 and 100 is 10.

Missy ordered french toast and she plans to leave a $7.00 tip to cover everyone. If she pays with a $20.00 bill, how much change should she receive? help asap
She will receive $13.00 change back,
hope i helped
Missy should receive $0.00 in change.
Explanation:To determine the change Missy should receive, we need to subtract the total amount she plans to pay from the cost of her food and the tip. If Missy's french toast costs $13.00 and she plans to leave a $7.00 tip, the total amount she plans to pay is $13.00 + $7.00 = $20.00. Since she pays with a $20.00 bill, the change she should receive is $20.00 - $20.00 = $0.00.

Which expression represents the distance between -14.6 and -5.2 on the number line?
If the expression represents the distance between -14.6 and -5.2 on the number line. The expression that represents the distance between -14.6 and -5.2 on the number line is 9.4.
What is distance?
Distance between these two points:
Distance = Larger value - Smaller value
Where:
Larger value = -5.2
Smaller value= -14.6
So,
Distance = -5.2 - (-14.6)
Distance = -5.2 + 14.6
Distance = 9.4
Therefore the expression that represents the distance between -14.6 and -5.2 on the number line is 9.4.
which of the following does not describe a rigid motion transformation? A.translating a figure 4 units up B.enlarging a figure by a scale factor of 2 C.rotating a figure 180 degrees D.reflecting a figure across the y-axis
Answer:
Option. B is not describing the a rigid transformation.
Step-by-step explanation:
Rigid transformation means an object when moved from one point to another, its position may change but size and shape of the object remains unchanged.
By this definition,
Option A. translating a figure 4 units up
In this statement only place is moving not the size, so it's Correct (describing rigid transformation)
Option B. Enlarging a figure by a scale factor of 2.
In this option size of the object is enlarged by a scale scale factor of 2, so this option is Not correct (not describing rigid transformation)
Option C. Rotating a figure by 180°
Again place is changing so its describing the rigid transformation. Correct (describing rigid transformation).
Option D. Reflecting a figure across the y axis.
Reflection means change in place. So the option is Correct (describing rigid transformation).
In a small town,there are two main sections called the Hill section and the lake section. The town has a population of 4298.The number of people who live in Hill section is 188 more than twice the number of people who live in the lake section. How many people live in each section of the town.
By setting up and solving an equation based on the information given in the problem, it can be determined that 1370 people live in the Lake section and 2928 people live in the Hill section of the town.
Explanation:The subject of this question is a mathematical word problem, which deals with the allocation of the population within two sections of a town- the Hill section and the Lake section. The total population is given, and a relationship between the two sections' populations is presented.
We can solve this issue by setting up an equation based on the information given. Let's define the number of people who live in the Lake section as 'x'. According to the problem, the number of people who live in the Hill section is 188 more than twice the number of people who live in the Lake section, which can be represented as '2x+188'.
Given that the total population of the town is 4298, these two populations add up to this total. So, the equation will be: x + (2x + 188) = 4298.
By simplifying this equation, you get 3x + 188 = 4298. Subtract 188 from both sides to isolate the variable term, resulting in: 3x = 4110. Then divide both sides by 3, you find that x = 1370.
So, 1370 people live in the Lake section, and since 2*1370+188 = 2928, 2928 people live in the Hill section.

There are 1370 people in the lake section and 3098 people in the Hill section.
Explanation:To solve this problem, let's use algebra.
Let x be the number of people who live in the lake section.
According to the problem, the number of people who live in the Hill section is 188 more than twice the number of people who live in the lake section, so the number of people who live in the Hill section would be 2x + 188. The total population of the town is 4298, so we can set up the equation x + (2x + 188) = 4298.
Simplifying this equation, we get 3x + 188 = 4298.
Subtracting 188 from both sides, we get 3x = 4110.
Dividing both sides by 3, we get x = 1370. Therefore, there are 1370 people who live in the lake section and 2(1370) + 188 = 3098 people who live in the Hill section.

Gabrielle's age is two times Mikhail's age. The sum of of their age is 66. What is Milkhail's age?
Final answer:
To find Mikhail's age, set up the equations based on the given information; Gabrielle's age is twice Mikhail's and their combined age is 66. Solving the equations shows that Mikhail is 22 years old.
Explanation:
The given problem is about determining Mikhail's age when Gabrielle's age is two times Mikhail's age and together their ages sum up to 66. We can set up equations to solve this problem. Let's denote Gabrielle's age as G and Mikhail's age as M.
From the problem we have two equations:
G = 2M (Gabrielle is twice as old as Mikhail)
G + M = 66 (Sum of their ages)
We can substitute the first equation into the second:
2M + M = 66
3M = 66
M = 66/3
M = 22
Therefore, Mikhail's age is 22 years old.

Step-by-step explanation:
I had a different A pex question but it was still relatively the same answer but i don't want anyone getting the answer wrong due to confusion so my answer was
Answer: T(c)=c+160/4
The function T(c), which is the inverse of C(t), is T(c) = (c + 180) / 6.
Explanation:To find the inverse function T(c), we first have to rewrite the original function C(t) in terms of c. So, if C(t) = 6t - 180, we write it as c = 6t - 180.
Next, we swap the roles of c and t, so now t becomes the function of c i.e., we get t = 6c - 180.
Finally, we solve this equation for c to get the inverse function. Doing so will give us c = (t + 180) / 6. Hence the inverse function is T(c) = (c + 180) / 6.

Use the ^ symbol (Shift+6 on the keyboard) to signify an exponent. For example, for 2 to the third power, enter 2^3. The domain for f(x) and g(x) is the set of all real numbers. Let f(x) = 5x2 − 4x and g(x) = 5x + 1. Find f + g. Incorrect feedback has been removed from the screen. Fill in the blank text field 1
Solution
f(x) = 5[tex]x^{2}[/tex] - 4x
and g(x) = 5x + 1
f + g is nothing but addition of f(x) and g(x)
Therefore, f + g = f(x) + g(x)
= 5[tex]x^{2}[/tex] - 4x + 5x + 1
Simplify the like terms, here -4x and 5x are the like terms.
f + g = 5[tex]x^{2}[/tex] + 1x + 1 [ 5x - 4x = 1x which is nothing but x]
f + g = 5[tex]x^{2}[/tex]+ x + 1
Thank you :)
The sum of the functions f(x) = 5x^2 − 4x and g(x) = 5x + 1 is found by adding the corresponding terms, resulting in the simplified function f(x) + g(x) = 5x^2 + x + 1.
To find the sum of the functions f(x) and g(x), you simply add the corresponding terms of each function together. Since the question gives us functions defined by f(x) = 5x2 − 4x and g(x) = 5x + 1, we combine these like so:
f(x) + g(x) = (5x2 − 4x) + (5x + 1).
To simplify, you combine the like terms:
f(x) + g(x) = 5x2 − 4x + 5x + 1
Now combining -4x and +5x:
f(x) + g(x) = 5x2 + (5x − 4x) + 1 = 5x2 + x + 1.
This final expression represents the sum of the functions f and g.
Identify the coordinates of four points on the line with each given slope and y-intercept. 0.2, y-intercept = 0.3
Slope = 0.2 and y-intercept = 0.3
The slope intercept form of line is
y=mx + b where m is the slope and b is the y intercept
So equation becomes y = 0.2 x + 0.3
To find coordinates of 4 points , we plug in some number for x and find out y
x y = 0.2 x + 0.3
0 y = 0.2 (0) + 0.3= 0.3
1 y = 0.2 (1) + 0.3= 0.5
2 y = 0.2 (2) + 0.3= 0.7
3 y = 0.2 (3) + 0.3= 0.9
Four coordinates are (0,0.3) (1,0.5) (2,0.7) (3,0.9)
