length of the ribbon is 120 M. what is the length of 7/15 of the ribbon?
Answer:
56 M
Step-by-step explanation:
Reduce fractions to their lowest terms equivalents
Multiply the numerators and denominators of the fractions separately
[tex]\frac{7}{15}[/tex] * 120 = convert to fraction
[tex]\frac{7}{15}[/tex] * [tex]\frac{120}{1}[/tex] = convert to fraction
[tex]\frac{7 * 120}{15}[/tex] = apply fraction rule [tex]\frac{a}{b}[/tex] * [tex]\frac{c}{d}[/tex] = [tex]\frac{a * c}{b * d}[/tex]
[tex]\frac{7 * 120}{15 *1}[/tex] = apply rule a * 1 = a 15 * 1 = 15
[tex]\frac{120}{15}[/tex] = 8 divide the numbers
7 * 8 = 56 multiply the numbers
List all the elements of the following set. Use set notation and the listing method to describe the set. { 2,4,8,...,256}
All the elements of the given set {2,4,8,...,256} are - {2, 4, 8, 16, 32,64, 128, 256} that are total 8 in numbers.
The set is formed by the number of objects in a particular manner, these objects are called elements of the set. The elements of the set are written inside a curly bracket separated by a comma in a particular or specific order.
There are two methods to represent the set and its elements that are:
Set notation: define the elements and properties of sets using symbols that help in describing the relationship between elements in the set.in this case, {[tex]2^{1},2^{2},2^{3},2^{4},2^{5},2^{6},2^{7},2^8[/tex]} as we know,
so the set notation would be :
= {x:x = [tex]2^{n}[/tex], n∈N and 1 ≤ n ≤ 8}
listing method: simple method that include the members or elements of the set are written as a list, separated by the comma and enclosed within the curly braces.The listing method: {2, 4, 8, 16, 32,64, 128, 256}\
Thus, the above mention set is all the elements of the set.

Determine which of the given points are on the graph of the equation.
Equation: x² + y2 = 2
Points: (1, -1), (-1,0), (1,1)
Which of these points are on the graph of the equation? Select all that apply.
A. (1, -1)
B. (1,1)
C. (-1,0)
D. None of the points are on the graph.
Answer:
D. none
Step-by-step explanation:
to figure out if the point is on the graph, take the x value and plug it in to the x coordinate, do the same for y. if the values truly add up to 2, then it is on the graph. Since none of the values add up to 2, they are not on the graph.
Given: g(t) =t+5 and h(t) = 3t-2
Find: (goh)(-4+t)
Answer:
3t - 9Step-by-step explanation:
Given:
g(t) = t + 5 and h(t) = 3t - 2Find the composite function (g·h)(t):
(g·h)(t) = g(h(t)) = (3t - 2) + 5 = 3t + 3Find (g·h)(-4 + t):
(g·h)(-4 + t) = g(h(-4 + t)) = 3(-4 + t) + 3 = -12 + 3t + 3 = 3t - 9The given information is,
→ g(t) = t + 5
→ h(t) = 3t - 2
Now we have to,
find the composite function (g•h)(t),
→ (g•h)(t)
→ g(h(t))
→ (3t - 2) + 5
→ 3t + 3
Let's find the (g•h)(-4 + t):
→ (g•h)(-4 + t)
→ g(h(-4 + t))
→ 3(-4 + t) + 3
→ -12 + 3t + 3
→ 3t - 9
Hence, the value is 3t - 9.
Nolan and his children went into a grocery store and he bought $8 worth of apples
and bananas. Each apple costs $2 and each banana costs $0.40. He bought 5 times as
many bananas as apples. By following the steps below, determine the number of
apples, 2, and the number of bananas, y, that Nolan bought.
To solve this problem form the system of equations first, then solve them to find the values of the variables.
Nolan bought 2 apples and 10 bananas.
It's given that,
Nolan and his children bought fruits (Apples and bananas) worth $8.Cost of each apple and bananas are $2 and $0.40 respectively.Let the number of bananas he bought = y
And the number of apples = x
Therefore, cost of the apples =$2x
And the cost of bananas = $0.40y
Total cost of 'x' apples and 'y' bananas = $(2x + 0.40y)
Equation representing the total cost of fruits will be,
(2x + 0.40y) = 8
10(2x + 0.40y) = 10(8)
20x + 4y = 80
5x + y = 20 --------(1)
If he bought 5 times as many bananas as apples,
y = 5x ------(2)
Substitute the value of y from equation (2) to equation (1),
5x + 5x = 20
10x = 20
x = 2
Substitute the value of 'x' in equation (2)
y = 5(2)
y = 10
Therefore, Nolan bought 2 apples and 10 bananas.

A baby panda born at a national zoo weighed 8 ounces at birth and reached 75 pounds
at one year
What was the panda's growth rate per month? Per week?
of age.
Here, we need to find the monthly and the weekly growth rate
The monthly growth rate is 99.33 ounces and the weekly growth rate is 22.9 ounces
Weight at birth = 8 ounces
Weight at one year =75 ounces
1 pound = 16 ounces
75 pounds = 1200 ounces
Additional weight after birth = Weight at one year - Weight at birth
= 1200 ounces - 8 ounces
= 1,192 ounces
There are 12 months in a year
Growth rate per month = Additional weight after birth / 12
= 1,192 / 12
= 99.33 ounces per month
There are 52 weeks in a year
Growth rate per week = Additional weight after birth / 52
= 1,192 / 52
= 22.9 ounces per week

Please answer ASAP question is in pic^
Answer:
Step-by-step explanation:
Original equation
√x+6-4 = x
Isolate
√x+6 = 4+x
Raise both sides to the second power
(√x+6)2 = (4+x)2
After squaring
x+6 = x2+8x+16
Rearranged equation
x2 + 7x + 10 = 0
This equation has two rational roots:
{x1, x2}={-2, -5}
Original equation, root isolated
√x+6 = 4+x
Plug in -2 for x
√(-2)+6 = 4+(-2)
Simplify
√4 = 2
Solution checks !!
Solution is:
x = -2
Original equation, root isolated
√x+6 = 4+x
Plug in -5 for x
√(-5)+6 = 4+(-5)
Simplify
√1 = -1
Solution does not check

Dana can type nearly 90 words per minute. Use this information to find the number of hours it will take her to type 2.6 x 105 words ,convert between standard decimal notation and scientifc
We can solve this problem by using the fact that speed of typing is defined as the words typed in unit time.
Dana will type [tex]2.6\times 10^5[/tex] words in 48.15 hours.
It's given in the question,
Dana can type 90 words per minute.Since, 1 minute = [tex]\frac{1}{60}[/tex] hours
Therefore, number of words she can type = [tex]\frac{90}{\frac{1}{60}}[/tex]
= 90×60
= 5400 words per hour
She types [tex]2.6\times 10^5[/tex] words in 'x' hours.Number of words Dana types with the given speed in 'x' hours = Speed of typing × Time
= [tex]5400\times x[/tex]
Therefore, [tex]5400\times x =2.6\times 10^5[/tex]
[tex]5400x=260000[/tex]
[tex]x=\frac{260000}{5400}[/tex]
