Answers

Answer 1

Answer:

The answer is B.

Step-by-step explanation:

You can solve this problem by plugging in 2 for x in the given equations.

2(2) - 3 = 19 is false

3(2) + 2 = 8 is true

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.

C. -26x2 + 21x - 15
D. 2x2 + 14x - 2

Answers

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.

Step-by-step explanation:

Answer:

Angle 7 = 56 °

Step-by-step explanation:

Angles 8 and 7 = 180 degrees

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?

Answers

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?

Answers

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°.

Answers

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?

Answers

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

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

Answers

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.
