Answer:
There are 50 students in total in the school play, acting and working behind the scene.
Step-by-step explanation:
Since the statement indicates that 30% of the scholars are working as stagehands, you can subtract this from 100% that represents the total amount of student in the school play to find the percentage that are actors and actresses:
100%-30%=70%
Now, as you know that 70% of the students are actors and actresses and the statement indicates that they are 35, you can use a rule of three to find the amount of students that represent 100%:
70% → 35
100% → x
x=(100*35)/70
x=50
According to this, the answer is that there are 50 students in total in the school play, acting and working behind the scene.

Use the following numbers, 4, 30, and 21 to create an equation equal to 1. You may only use each number once. You can use any operation you want to.
Answer:
sqrt(30-21)-sqrt(4)=1
Step-by-step explanation:
I found that sqrt(30-21)-sqrt(4)=1 since sqrt(30-21)=sqrt(9)=3 and sqrt(4)=2 so 3-2=1

Answer:
B. Larger groups tended to take less time to solve the puzzle
Step-by-step explanation:
If you look at the graph, you can see that farther to the left the dots are higher, which means that the number of people are taking longer than the people to the right of the graph whose dots are lower, representing that it takes less time for the larger groups to solve the puzzle.

Answer:
12 gallons
Step-by-step explanation:
If it takes 20 h for 5 gallons to be filled, it takes 4 h for 1 gallon to be filled. This is the ratio. You multiply 4 h by 12 to get 48 h, so you multiply 1 gallon by 12 as well. This is 12 gallons.

Write a system of equations to describe the situation below, solve using any method, and Fill in the blanks.
Natalie is a salon owner. Yesterday, she did 3 haircuts and colored the hair of 1 client,
charging a total of $239. Today, she did 2 haircuts and colored the hair of 1 client, charging a
total of $192. How much does Natalie charge for her services?
Natalie charges $___
for a haircut and $__
for a coloring
Answer:
1 haircut = 47 dollars
1 colouring = 98 dollars
Step-by-step explanation:
Let [tex]x[/tex] be equal to the cost of 1 haircut.
Let [tex]y[/tex] be equal to the cost of 1 colouring treatment.
1) Form equations
Equation 1: 3 haircuts + 1 colour = 239 dollars
⇒ [tex]3x+y=239[/tex]
Equation 2: 2 haircuts + 1 colour = 192 dollars
⇒ [tex]2x+y=192[/tex]
2) Solve the system of equations
Subtract equation 2 from equation 1 to cancel out y (elimination)
- [tex]3x+y=239\\2x+y=192[/tex]
⇒ [tex]3x-2x+y-y=239-192\\x=47[/tex]
Therefore, Natalie charges 47 dollars for 1 haircut.
Plug x back into one of the equations to solve for y
[tex]2(47)+y=192\\94+y=192[/tex]
Subtract both sides by 94
[tex]94+y-94=192-94\\y=98[/tex]
Therefore, Natalie charges 98 dollars for 1 colouring treatment.
I hope this helps!

Find the slope of the line graphed below.
Given:
The graph of a line.
To find:
The slope of the graphed line.
Solution:
From the given graph it is clear that the line passes through the points (-2,2) and (2,5). So, the slope of the line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{5-2}{2-(-2)}[/tex]
[tex]m=\dfrac{3}{2+2}[/tex]
[tex]m=\dfrac{3}{4}[/tex]
Therefore, the slope of the given graphed line is [tex]m=\dfrac{3}{4}[/tex].

What is the speed of a car that traveled a
total of 300 kilometers north in 2 hours?
Speed = Distance/Time
So, speed
= 300 km/2h
= 150km/h
= (150 × 1000m) / 3600s
= 150000m/3600s
= 41.66m/s [approximately]
prove that underroot 3-underroot 5 is irrational.
Please quickly I need this answer
Answer:
See Explanation
Step-by-step explanation:
Let us assume that [tex] \sqrt 3 - \sqrt 5[/tex] is a rational number.
So, it can be expressed in the form of [tex] \frac{p}{q} [/tex] where p and q are integers.
[tex]\therefore \sqrt 3 - \sqrt 5=\frac{p}{q}[/tex]
[tex]\therefore \sqrt 3 =\frac{p}{q}+ \sqrt 5[/tex]
[tex]\therefore \sqrt 3 =\frac{p+q\sqrt 5}{q}[/tex]
Squaring both sides:
[tex] (\sqrt 3) ^2 =\bigg(\frac{p+q\sqrt 5}{q}\bigg ) ^2 [/tex]
[tex]\therefore 3 =\frac{p^2 +5q^2 +2\sqrt 5 pq}{q^2 } [/tex]
[tex]\therefore 3q^2 ={p^2 +5q^2 +2\sqrt 5 pq}[/tex]
[tex]\therefore 0 = p^2 +5q^2 -3q^2 +2\sqrt 5 pq [/tex]
[tex]\therefore - 2\sqrt 5 pq=p^2 +2q^2 [/tex]
[tex]\therefore \sqrt 5 = \bigg (\frac{p^2 +2q^2}{-2pq} \bigg) [/tex]
[tex]\therefore \sqrt 5 = - \bigg(\frac{p^2 +2q^2}{2pq} \bigg) [/tex]
Since, p and q are integers so [tex] - \bigg(\frac{p^2 +2q^2}{2pq} \bigg) [/tex] is rational.
[tex]\therefore \sqrt 5 [/tex] is also rational.
But it contradicts the fact that [tex]\sqrt 5 [/tex] is irrational.
Hence, our assumption that [tex] \sqrt 3 - \sqrt 5[/tex] is rational is wrong.
[tex] \therefore \sqrt 3 - \sqrt 5[/tex] is irrational.
Find the length of the third side. If necessary, write in simplest radical form.
(screenshot provided)
no links please ;')
Answer:
the length of the third side (the hypotenuse) is 7
Step-by-step explanation:
Solve this by using the Pythagorean Theorem:
(2√10)² + 3² = (hypotenuse)²
Then (hypotenuse) = √(40 + 9) = √49 = 7
Answer:
7
Step-by-step explanation:
2 root 10 ^2 is 40
3 squared is 9
root of 49
Each length of the side of square B is twice the length of the side of square A.
John says that this means the area of square B is twice the area of square A.
Is John right?
Justify your answer.
Answer:
yes
Step-by-step explanation:
because the area of square is l² so John is righrt
Answer:
Area of square= ²
Area of square A= ²
Area of square B = ?
let the length of square A = x
Area of square A =x²
then the length of square B = 2x
Area of square B =2x²
x²means area of square A
so Area of square B =2 times area of squarf A

During the day, Lola's dog is tied by rope to a tree in the center of her yard. The scale drawing below shows the area that the dog has to run, in inches. If the actual length of the rope is 11 2/3 feet, what is the scale used in the drawing?
Answer:
5 /448
Step-by-step explanation:
Radius in drawing = 1 9/16 in
The actual length of rope = 11 2/3 feets
Converting actual length to inches :
1 feet = 12 inches
11 2/3 feets = (11 2/3) * 12 = 140 inches
To obtain the scale used, we divide the Radius in the drawing by the actual length :
1 9/16 ÷ 140
25 /16 ÷ 140
25 /16 * 1 /140
= 25 / 2240
= 5 /448
Hence, scale is 5 /448 times the actual length of drawing
Hence :
The scale used is :
1 feet = 7.4666 inches

The height of the red triangle is 1/2 the top or bottom white triangle. That's because the diagonals and the horizontal line all meet in the middle.
The base of the red triangle is equal to 1/2 the length of the base.
Formula
Area red = 1/2 b * h
Solution
b = 1/2
h = 1/2
Area = 1/2 * 1/2 * 1/2
Area = 1/8

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
What is the value of x?
Answer:
x = 59
Step-by-step explanation:
combine all four angle measure expressions and set equal to 360°, then solve
x + x + 2x + 3 + 2x + 3 = 360
6x + 6 = 360
6x = 354
x = 59
