Length of line DE = 20
Step-by-step explanation:
The scale factor from ΔABC to ΔDEF is 2.
Line AB is similar to line DE.
So, we need to multiply the length of line AB by 2 to get the length of line DE:
10 × 2 = 20

please answer , I have no idea how to do this
Answers
Using the table, it is found that there is a 77% probability that a seventh grader chosen at random will play an instrument other than bass.
-----------------------------
A probability is the number of desired outcomes divided by the number of total outcomes.The table is given at the end of this question.From the table:
There are 12 + 10 + 9 + 12 = 43 7th grade students.Of those, 33 play an instrument other than the bass.Then:
[tex]p = \frac{33}{43} = 0.77[/tex]
0.77 = 77% probability that a seventh grader chosen at random will play an instrument other than bass.

Cheese sticks that were previously priced at "10 for $1" are now "4 for $1". Find each percent change
Answers
Answer:
The price per cheese stick was increased by 150%.
The amount of cheese sticks per $1.00 has decreased by 60%.
Step-by-step explanation:
The price per cheese stick was $0.10
1.00 (dollar) divided into 10 (cheese sticks) gives you 0.1, which means each cheese stick costs $0.10The current price per cheese stick is $0.25
1.00 (dollar) divided into 4 (cheese sticks) gives you 0.25, which means each cheese stick costs $0.25That means the price per cheese stick was raised by 150%.
That also means the amount of cheese sticks you could buy for $1.00 has decreased by 60%.

The equation y =f(x) is graphed on the coordinate plane. A function, g(x). is the result of translating the graph of fuxi to the left 2 units and up 4 units. Which is an equation for g(x)?
A)g(x)=f(x - 2)+4
B)g(x) = f(x + 2) + 4
C)g(x)=f(x-4)-2
D)g(x)=f(x + 4)-2
Answers
Answer:
A
Step-by-step explanation:
g
[tex]g(x) = f(x - 2) + 4[/tex]
A function assigns the value. The equation of the function g(x) will be f(x-2)+4.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given f(x) is a function which is shifted two units to the right and 4 units upwards. Therefore, in the function f(x) we need to add -2 to the value of the x for the function to move right, while we need to add 4 to the overall function to move it four units upwards.
Hence, the equation of the function g(x) will be f(x-2)+4.

Oliver drove 278 miles in 4 hours how much hours does it take him to drive 139 miles
PLSSS HELP
Answers
Answer:
34.75 i think
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf 2 \ hours}}[/tex]
Step-by-step explanation:
Let's set up a proportion to solve. Use the following setup:
[tex]\frac {hours}{miles}=\frac{hours}{miles}[/tex]
We know that it takes Oliver 4 hours to drive 278 miles.
[tex]\frac {4 \ hours}{278 \ miles}=\frac{hours}{miles}[/tex]
We don't know how long it takes him to drive 139 miles. Therefore, we use the variable x for hours, because it is unknown.
[tex]\frac {4 \ hours}{278 \ miles}=\frac{x \ hours}{139 \ miles}[/tex]
[tex]\frac {4 }{278 }=\frac{x \ hours}{139 }[/tex]
We are solving for x, the hours it takes him to drive 139 miles. The variable must be isolated. It is being divided by 139 and the inverse of division is multiplication. Multiply both sides of the equation by 139.
[tex]139*\frac {4 }{278 }=\frac{x \ hours}{139 }*139[/tex]
[tex]139*\frac {4 }{278 }={x }[/tex]
[tex]2=x[/tex]
It takes Oliver 2 hours to drive 139 miles.

A quantity with an initial value of 650 grows exponentially at a rate of 20% every week. What is the value of the quantity after 70 days, to the nearest hundredth?
Answers
Answer:
4024.62
Step-by-step explanation:
the value in 70 days can be determined using his formula
FV = P (1 + r)^n
FV = Future value
P = Present value = 650
R = growth rate = 20%
N = number of weeks = 70 / 7 = 10 weeks
650 x (1.2)^10 = 4024.62
Answer:
The Answer is 4024.62
