Alright, so we know that there are 7 days a week with 24 hours per day.
24x7= 168 hours a week.
Convert the problem to an equation using the percentage formula: P% * X = Y.
Let's take the 40% that is Sleep and use it in the percentage formula with the 168 hours.
40%x168= roughly 67 hours.
Hope this helped!
Which one is the correct one
Step-by-step explanation:
Sum of opposite angles are supplementary,
x + 60 + 3x = 180
4x + 60 = 180
4x = 180 - 60
4x = 120
x = 120 / 4
x = 30
Select the correct answer. Simplify the polynomial expression. 3x(-2+7)-5(x -1)(4x-3)
A. -26x2 + 56x - 15
B. 14x2 - 14 + 15x
C. -26x2 + 21x - 15
D. 2x2 + 14x - 2
Answer:
-20x^2 + 56x - 15
Step-by-step explanation:
3x(−2+7)−5(x−1)(4x−3)
Add −2 and 7 to get 5.
3x×5−5(x−1)(4x−3)
Multiply 3 and 5 to get 15.
15x−5(x−1)(4x−3)
Use the distributive property to multiply −5 by x−1.
15x+(−5x+5)(4x−3)
Apply the distributive property by multiplying each term of −5x+5 by each term of 4x−3.
15x−20x^2+15x+20x−15
Combine 15x and 20x to get 35x.
15x−20x^2+35x−15
Combine 15x and 35x to get 50x.
50x−20x^2−15
Swap terms.
-20x^2 + 56x - 15

In the diagram, the measure of angle 8 is 124º, and the measure of angle 2 is 84°
Answer:
whats the question?
Step-by-step explanation:
Answer:
Angle 7 = 56 °
Step-by-step explanation:
Angles 8 and 7 = 180 degrees
To get the degree of angle 7 subtract 124 from 180
180 - 124 = 56 degrees
Angle 7 = 56 degrees
Raul made 4 cups of fruit salad. one serving of fruit salad is 1/2 cup. how many serving of fruit of fruit salad did raul make?
Answer:
Raul made 8 servings of fruit salad
Step-by-step explanation:
Here, we want to get the number of servings made by Raul
From the question;
1 serving = 1/2 cup
x servings = 4 cups
Thus;
4 * 1 = x * 1/2
x = 4/(1/2)
x = 8 servings
A circle is centered on point B. Points A, C and D lie on its circumference.
If ZABC measures 40°, what does ZADC measure?
Given:
A circle is centered on point B.
Points A, C and D lie on its circumference.
If [tex]m\angle ABC[/tex] measures 40°.
To find:
The [tex]m\angle ADC[/tex].
Solution:
Central angle theorem: According to this theorem, the central angle is equal to the twice of inscribed angle on the same intercepted arc.
In the given figure [tex]\angle ABC[/tex] is the central angle and [tex]m\angle ADC[/tex] is the inscribed angle on the same arc AC.
Using central angle theorem, we get
[tex]m\angle ABC=2m\angle ADC[/tex]
[tex]40^\circ=2m\angle ADC[/tex]
[tex]\dfrac{40^\circ}{2}=m\angle ADC[/tex]
[tex]20^\circ=m\angle ADC[/tex]
Therefore, the measure of angle ADC is 20°.

PLZZZ HELPPPP, How many 2 inch cubes will fit into the box below if it is filled completely full?
Answer:
30 cubes
Step-by-step explanation:
10 x 4 x 6 = 240 in³
2 x 2 x 2 = 8 in³
240/8 = 30 cubes
Answer:
I believe 240
Step-by-step explanation:
Since ur multtiplying
10 times 4 times 6 you get 240
Express as a trinomial.
(3x+8)(x + 6)
Answer:
multiply 3x by x then multiply 8 by 6 and get 48. since 8 and 6 are products of 48 they give a sum of 14 therefore your trinomial is
3x²+14x+48
please help I have no clue how to do this
Step-by-step explanation:
It's a question of trigonometry.
You need to remember that tangent (tan) stands for Perpendicular / Base.
So, tan P = QR / PR
By Pythagoras Theorem,
34² = 30² + x²
x² = 34² - 30²
x² = 1156 - 900
x² = 256
x = 16
Now, placing the values,
tan P = 30 / 16
tan P = 1.875

a number times 12 is 72. which equation fits this statement?
Answer:
12x = 17
Step-by-step explanation:
So, this is a standard variable equation, so a number (I did x because I'm basic) times, multiplied by, whatever 12 = 72
So a number times 12 is 72 = 12x = 17
Now, if you wanted to actually solve this equation, you just have to do inverse operations:
17 ÷ 12 = 1.4167 (rounded)
So x = 1.4167

On a coordinate plane, triangle A B C is shown. Point A is at (0, 0), point B is at (3, 4), and point C is at (3, 2).
What is the area of triangle ABC?
2.5 square units
3 square units
3.5 square units
4 square units
Answer:
It is B. 3 square units, i took the test and got a 100%
Step-by-step explanation:
edge2021
The area of the triangle on a coordinate plane is 3 square units option (B) 3 square units is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have a triangle on a coordinate plane shown in the picture.
Triangle ABC has vertices A, B, and C at (0, 0), (3, 4), and (3, 2).
As we know, the area of the triangle is given by:
Area = (1/2)heightxbase length
Or
Area = (1/2)ADxBC
Area = (1/2)3x2
Area = (6/2)
Area = 3 square units
Thus, the area of the triangle on a coordinate plane is 3 square units option (B) 3 square units is correct.

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.

Answer:
x = 140°
Step-by-step explanation:
x is a supplementary angle to 40°. This means that when added together equals 180°
x = 180° - 40° = 140°
Answer:
Step-by-step explanation:
Since I can't see slide 2 I don't know what pattern they want you to see, but, I do know that when you have a line with an angle... the other side , here that is the 'X' will always be 180 - 40 = X
X is easy to solve that way. it's , ofc 140 :D
