Answer:
She take 20 cookies to her students.
Step-by-step explanation:
Because 120÷6 is 20
and 20×6 is 120
Answer:
20
Step-by-step explanation:
She baked 120 cookies.
To solve this, use the equation: 120/1/6
In this equation, the 1 is useless. The real equation is 120/6 or 120 divided by 6.
12/6=2
After evaluating 12 divided by 6, add a zero to the end of the answer since you're trying to find 120 divided by 6.
The answer should be 20

The mean age of 5 people in a room is 39 years.
A person enters the room.
The mean age is now 36.
What is the age of the person who entered the room?
Answer:
fast multiply 5 by 39 to get the total age of the five people now as you are told those per 5 so imagine the six person being you if you enter you're going to add to their ages so they mean is going to be for six people so take the six people x their mean age now we have two different total ages for the five people and for the six people subtract the total age of the 5 from the 6th total ages to get the age of the person who entered the room if you don't understand please ask me and be willing to help
Answer:
The age of the person who entered the room is 21.
Step-by-step explanation:
Mean of 5 peoples = 39
i.e.
Sum / 5 = 39
Sum = 39 x 5
Sum = 195
Mean after one person enters the room = 36
Let x be the age of the new person.
Then
Mean = (Sum + x)/ 6
36 = (195 + x)/6
36 x 6 = 195 + x
216 = 195 + x
x = 216 - 195
x = 21

Matt spins the spinner above 400 times and it lands on six 43 times. How many times out of the 400 spins would you predict spinner to land on six.
Answer:
50 times
Step-by-step explanation:
Given that:
Number of spins = 400
Sample space = (1, 2, 3, 4, 5, 6, 7, 8)
Probabililtybof landing on 6 on a single spin :
Probability = required outcome / Total possible outcomes
P(landing on a six) = 1/ 8
Probability of landing on a 6 in 400 spins :
1/8 * 400 = 50 times
the perimeter of a rectangular garden used 86 feet of barbed wire. The length of the garden is 7 feet more than its width. Find the dimensions of the garden.
answer with solution?
Answer:
Step-by-step explanation:
perimeter of a rectangle = twice the length plus twice the width
P = 2L + 2W equation 1 P = 86 ft
Given the length is seven feet more than the width
L = W + 7 equation 2
Substitute equation 2 into equation 1
P = 2(W+7) + 2W = 86 ft
2W +14 + 2W = 86 ft
4W = 86 - 14
W = 72 / 4
W = 18 feet

Answer:
Step-by-step explanation:
Area of Yellow Rectangle
Area = L * W
Area = 25 * 11
Area = 275
Area of Parallelogram
Area = Base * height
Area = 12 * 4

Which of the following is the discriminant of the polynomial below x^2+4x+5
Answer:
[tex]\huge\boxed{\sf Discriminant = -4}[/tex]
Step-by-step explanation:
Comparing it with quadratic equation [tex]ax^2 + bx + c = 0[/tex], we get:
a = 1 . b = 4 and c = 5
So,
Discriminant = [tex]b^2-4ac[/tex]
D = (4)²-4(1)(5)
D = 16 - 20
D = -4
Hence,
Discriminant = -4

A person's height is 5-ft 3-in. Their shadow has a length of 3-ft 6-in. If a nearby tree has a shadow of length 10-ft 4-in, what is the approximate height of the tree?
Answer: The height of tree = 15 ft. 6 inches
Step-by-step explanation:
Given: A person's height is 5-ft 3-in = [5 x (12 )+3 ] inches [ 1 ft= 12 inches]
= 63 inches
Their shadow has a length of 3-ft 6-in = [3 x 12+6] inches
= 42 inches
If a nearby tree has a shadow of length 10-ft 4-in = [10 x 12+4] inches
= 124 inches.
At the same time,
[tex]\dfrac{\text{Height of tree}}{\text{Height of person}}=\dfrac{\text{Length person's shadow}}{\text{Length of tree's shadow}}\\\\\dfrac{\text{Height of tree}}{63}=\dfrac{124}{42}\\\\\Rightarrow\ \text{Height of tree}=\dfrac{124}{42}\times63=186\ inches\\\\=\dfrac{186}{12}= 15.5 ft\ or\ 15 ft.\ 6\ inches.[/tex]
Hence, the height of tree = 15 ft. 6 inches
