First, she subtracts 40% from 100% to get 60%.
Then she finds the number that is 60% of 200.
Is Sasha correct? Use words and numbers to explain your answer.

A company orders 18 boxed lunches from a deli for $123.30. Assume each boxed lunch is the same price. If c represents the total cost in dollars and cents of the lunch order for any number, b, of boxed lunches ordered, write a proportional equation for c in terms of b that matches the context.
Answer:
a. $6.85
cents = 683
b. c=k/b
Step-by-step explanation:
18c=123.30
c=123.30÷18=6.85$
to cents = $6.85×100=683
b.
b=lunches orderd
c=each lunches box
k=total cost
c=k/b

The average high temperatures in degrees for a city are listed.
58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
If a value of 103° is added to the data, how does the mean change?
The mean increases by 1.7°.
The mean decreases by 1.7°.
The mean increases by 8.6°.
The mean decreases by 8.6°.
Answer:
The mean increases by 1.7°
Step-by-step explanation:
1) Find the mean of the numbers given first
Mean = sum of number ÷ number of numbers
Sum of numbers = 58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 = 965
Number of numbers = 12
965 ÷ 12 = 80.41666....2) Find the mean of numbers including the additional 103
Sum of numbers = 58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 + 103 = 1068
Number of numbers = 13
1068 ÷ 13 = 82.15384623) Find the difference
If we use the results rounded to one decimal place we will be left with 80.4 and 82.2
82.1538462 - 80.41666... = 1.7The answer closest to the options given would be 'The mean increases by 1.7'Hope this helps, have a lovely day :)

What is an arithmetic sequence?It is a sequence where the difference between each consecutive term is the same.
Example:
2, 4, 6, 8, 10 is an arithmetic sequence.
We have,
Ball A.
Distance travel after n seconds = 50, 48, 46, 44, 42, 40,,,,,
Sum of nth term = n/2[100 + (n - 1)2 ]
Ball B.
Distance travel after t seconds = 30, 28, 26, 24, 22, 20,,,,,
Sum of nth term = n/2 [60 + (n - 1)2]
Now,
n/2 [100 + (n - 1)2] + n/2 [60 + (n - 1)2] = 420
50n + 2n - 2 + 30n + 2n - 2 = 420
80n + 4n - 4 = 410
84n = 414
n = 414/84
n = 5
Thus,
The ball takes 5 seconds to meet.

Answer:
y = -180 + 3x
Step-by-step explanation:
Because AB = AC -> ABC is a isosceles triangle -> B = C
Because AB = BD -> ABD is an isosceles triangle -> A = D -> x = D
We have ADB + ADC = 180 -> x + ADC = 180 -> ADC = 180 - x (1)
We have x = D, and BAD + ADB + ABD = 180 -> ABD = 180 - 2x but B = C -> C = 180 - 2x (2)
With (1) and (2) We have DAC + ACD + ADC = 180
-> y + 180 -2x + 180 -x = 180
-> y + 360 - 3x = 180
-> y = -180 + 3x

y=3x-180

Which of the following show a percent increase greater than 50%? Select all that apply.?
A jacket that costs $18 is sold to the customer for $25.
A hat that costs $8 is sold to the customer for $12.
A pair of shoes that costs $20 is sold to the customer for $35.
A shirt that costs $12 is sold to the customer for $20
Answer: A pair of shoes that costs $20 is sold to the customer for $35, and A shirt that costs $12 is sold to the customer for $20.
Step-by-step explanation:
1. Half (or 50%) of 20 is 10, so 20+10=30, but 35 is bigger than 30.
2. Half (or 50%) of 12 is 6, so 12+8=18, but 20 is bigger than 18.
A server wants to rearrange the tables into for identical rows of small and large tables. How can you rewrite 12 a plus 8B, so that the expression shows the number of small tables and the number of card tables in each row write your answer in the blanks (part b)
33) A student has a set of cards, Each cara nas a picture of one shape.
The table shows the number of cards that have a picture of each
shape. The student will randomly select one card from the set.
Shape Cards
Circle = 8
Pentagon = 12
Rectangle = 10
Square = 6
Triangle = 4
Which statement is true?
A) The probability of selecting a card with a picture of a circle is 5/8, and the probability of selecting a card that is not a picture of a circle is 3/8
B) The probability of selecting a card with a picture of a circle is 3/8, and the probability of selecting a card that is not a picture of a
circle is 5/8
C) The probability of selecting a card with a picture of a circle is 1/5, and the probability of selecting a card that is not a picture of a
circle is 4/5
D) The probability of selecting a card with a picture of a circle is 4/5, and the probability of selecting a card that is not a picture of a circle is 1/5
Answer: C The probability of selecting a card with a picture of a circle is 1/5, and the probability of selecting a card that is not a picture of a
circle is 4/5
Step-by-step explanation:
First you need to find the total amount of cards in the set by adding up all of the cards: 8 + 12 + 10 + 6 + 4 = 40
Then to find the probability of selecting a circle divide the number of cards that have a circle by the total number of cards: 8/40
You can simplify it to be 1/5 since 8/8 = 1 and 40/8 = 5
So the probability of a circle is 1/5
This means that the probability for all of the other shapes that are not a circle have to be 4/5-- but you can check by adding up the rest then dividing by 40:
12 + 10 + 6 + 4 = 32
32/40 --> 32/8 = 4 & 40/8 = 5
4/5

Answer:
Step-by-step explanation:
The question asks you to dilate the rectangle by a scale factor of 1/3.
KEY TERM:
Dilate by a scale factor: You make a shape bigger or smaller by multiplying by a number.
Here, we are dilating by a scale factor of 1/3. Therefore, to solve the problem, you have to multiply each coordinate by 1/3. Also, we are making the shape smaller because we are multiplying by a fraction.
___
STEP 1: LINE UP ALL THE COORDINATE PAIRS
Point U: (-6,6)
Point R: (-6,-3)
Point T: (9,6)
Point S: (9,-3)
Now the easy part is done.
STEP 2: MULTIPLY BY 1/3
It is very important you know how to do this part because it determines the answer. So when i say "multiply by 1/3" i mean multiply each individual number by 1/3.
I'll explain for point u then do the rest:
Point U was originally: -6,6.
-6 x 1/3= -6/3= -2.
6x1/3= 6/3= 2
The "dilated" point U is: (-2,2). I multiplied each individual coordinate by 1/3, one by one.
Point R was originally: (-6,-3)
-6x1/3= -2
-3x1/3= -3/3= -1
The "dilated" point R is (-2,-1)
Point T was originally: (9,6)
9x1/3= 3
6x1/3= 2
The "dilated" point T is (3,2).
Point S was originally (9,-3).
9x1/3= 3
-3x1/3= -1
The "dilated' point S is (3,-1)
Finally, if you ever get confused about the order of the coordinates, it just stays the same. Like 9,-3 becomes the dilated 9 , dilated -3.
STEP 3: GRAPH THE NEW POINTS
see the screenshot, for reference :)
Answer:
Step-by-step explanation:
you dilate each coordinate by a scale factor of 1/3 , making the shape smaller.

Problem 1: Over time, houses can sink slightly due to shifts in the soil below. One house was built with its ground at sea level, and over a period of 7 years, it sank to an elevation of -1 5/16 feet. How much change each year in elevation of house?
Answer:
-3/16 feet a year
Step-by-step explanation:
since we have a whole number 1 (5/16), we can turn this into an improper fraction 16(from the one) +5=21/16, since we know the number of years (7) we can divide 21 by the number of years. 21/7=3. So it went down 3 feet a year. Hope this helped!

Answer:
Last option: Each term in the first sequence is four times the corresponding term in the second sequence
