Answer:The lengths of AB and EF are 10 and 2 respectively
If the triangle ABC and DEF are similar, based on the similarity theorem of a triangle;
AB/DE = BC/EF
5x/4 = 5/x
5x² = 20
x² = 20/5
x² = 4
x = 2
Since the value of x is 2, length of AB is 5x = 5(2) = 10
Since EF = x, hence EF = 2
The lengths of AB and EF are 10 and 2 respectively

The options 1,2 and 5 are the correct answer.
The given equation is 1.23/[tex]10^1[/tex]=0.123.
What is the division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.
Now,
1) 1.23/[tex]10^1[/tex]=0.123
Here LHS=RHS
2) 123/100=1.23
Here LHS=RHS
3) 12.3/[tex]10^0[/tex]=1.23
⇒ 12.3/1=12.3
So, LHS≠RHS
4) 0.123/10=1.23
⇒ 0.123/10 = 0.0123
So, LHS≠RHS
5) 1230/10³=1.23
⇒ 1230/1000
= 1.23
Here LHS=RHS
Therefore, the options 1,2 and 5 are the correct answer.

The graph shows the number of quarts picked and the amount of money the customer paid.
Another customer pays $8.75 for the strawberries she picks. What point (n, a) on the graph represents this?
Answer:
The point would be (2.5,8.75)
Because we know the customer paid $8.75, we use the y-axis to find this point. Then we'll find where the line meets 8.75 on the y-axis. This is at 2.5. We know that points are in the order of (x,y) therefore the point is (2.5,8.75)

Answer: The ratio is 18:3
Step-by-step explanation:
Answer: 6 to 1
Step-by-step explanation:
A ratio refers to a fraction. In this case the question asks how many players to coaches there are.
The word "to" means that is where the fraction bar goes.
Players/Coaches
There are 18 players and 3 coaches.
18/3
18 can be divided by 3, 6 times so the fraction can be simplified to
6/1 meaning there are 6 players for every coach.

HELP ME NOW PLEASEEEEEEEEE!
THANK YOU! <3<3<3
Answer:You just divide the original amount by 100 (move the decimal point over two places)
750 / 100 = 7.5
Now you multiply that by the interest rate, which in this case is 7.
7.5 x 7 = 52.5
Now finally, you multiply that by the amount of years. In this case, 3.
52.5 x 3 = 157.5
That would be the amount added after three years! Remember, this is simple interest. Compound interest is a little more complex.

solve - p'(5, -4) for the glide reflection where the translation is (x,y) -> (x - 2, y - 3) and the line of reflection is y = -x
Answer:
The Point in the coordinate plane is A(-5,-4)
Perpendicular or shortest Distance from line y=3 that is (-5,3) to point (-5,-4) is
When it is reflected through the line, y=3, the coordinate of point A (-5,-4) changes to (-5,3+7)= B(-5,10).
Now, the Point B is translated by the rule , (x,y)—->(x+6,y),
So,the point B is translated to, (-5+6,10)=(1,10)
(1,10) is the glide reflection of point A(-5,-4).
Step-by-step explanation:
Pamela is 8 years older than Jiri. The sum of their ages is 62. What is Jiri's age?
Answer:
Jiri's age = 27
Step-by-step explanation:
Let's use x for Jiri's age.
Jiri's age = x
And because Pamela is 8 years older:
Pamela's age = x + 8
Since their ages added up equal 62, the equation will be:
x + x + 8 = 62
2x + 8 = 62
2x + 8 - 8 = 62 - 8
2x = 54
2x/2 = 54/2
x = 27
And because Jiri's age is x, Jiri's age will therefore be 27.
Hope this helped!
Answer:
Jiri is 27 years old.
Step-by-step explanation:
Step 1: Declare variables
Let Jiri’s age be [tex]\displaystyle x[/tex] years old.Since Pamela is 8 years older than Jiri. Then, Pamela’s age is [tex]\displaystyle{8+x}[/tex] years old.
Step 2: Form an equation
The sum of their ages together equals to 62. Therefore, we can express in mathematics/equation of [tex]\displaystyle{x+8+x=62}[/tex] (sum of Jiri’s age and Pamela’s).
Step 3: Solve for x-term - add like terms (x-term)
[tex]\displaystyle{2x+8=62}[/tex]
Step 4: Subtract both sides by 8
[tex]\displaystyle{2x+8-8=62-8}\\\\\displaystyle{2x=54}[/tex]
Step 5: Divide both sides by 2
[tex]\displaystyle{\dfrac{2x}{2}=\dfrac{54}{2}}\\\\\displaystyle{x=27}[/tex]
Since Jiri’s age is defined as [tex]x[/tex] years old. Therefore, Jiri’s age is 27 years old.

Answer:
5. [tex]7^{5}[/tex]
6. [tex]27+15=42[/tex]
7. [tex]\frac{u}{10}=100[/tex] then multiply both sides by 10: [tex]u=100*10 \\u=1000[/tex]
8. [tex]28+r=128[/tex] subtract 28 from both sides: [tex]r=100[/tex]
9. So we are going to use the formula [tex]A=l*w[/tex]: [tex]A=4*2.5\\A=10[/tex]
10. So we are going to use the formula [tex]A=b*h[/tex]: [tex]A=9*4\\A=36[/tex]
