Answer:

6.626068 × 10-34 m2 kg / s

Step-by-step explanation:

The Planck constant, or Planck's constant, denoted h is a physical constant that is the quantum of electromagnetic action, which relates the energy carried by a photon to its frequency. A photon's energy is equal to its frequency multiplied by the Planck constant. The Planck constant is of fundamental importance in quantum mechanics, and in metrology it is the basis for the definition of the kilogram.

78=c-13

c=65

____________________

13                        65           78

Part A-  An inequality to represent the number of coats collected by seventh grade students is, c,    C > 65

Part B- The graph of the solution on a number line, i have attached image below.

Inequalities are the comparison of mathematical expressions, whether one quantity is greater or smaller in comparison to another quantity.

We use these symbols to represent inequalities,   '>' , '<',  '≥',  '≤'

Given Information,

    The seventh grade wants to break last year's record of 78 coats collected,

    They have already collected 13 coats,

A.   They need 65 more clothes to reach at the record of 78 clothes,

     If they wants to break the last year's record they should collect more  than 65 clothes,

So, the inequality is,   C≥65

B. Graph on a number is attached in image.

Hence, the number coat must be greater than 65

Answer:

Yes the equation is a linear one because it is an equation for a straight line.

Step-by-step explanation:

Answer:

Yes. Read below for explanation.

Step-by-step explanation:

y=3x+1 is in-fact linear. It is not a function though as it's y-intercept is 1 not 0. If you graphed this on a graphing calculator such as Desmos, it would create a line. It also uses slope-point formula which definitely makes it a line.

Answer:

Triangle C and Triangle D

Step-by-step explanation:

If you look closely at all of the different triangles, you can see that there are two pairs of congruent triangles.

Triangle A and Triangle E are congruent, both being right triangles and approximately the same size.

Triangle B and Triangle F are congruent, as both of them are isosceles triangles, and again, the same size.

The two that remain, Triangles C and D, are both scalene triangles, but they are not congruent to one another. Triangle C clearly has a smaller obtuse angle than Triangle D.

Answer:

y = -x + 3

Step-by-step explanation:

Slope intercept form is the form y = mx+b where m is the slope and b is the y intercept

Plugging in the values we get y=-x+3

Answer:

y = - x + 3

Step-by-step explanation:

y = mx + b

Slope m = -1.

y = - x + b

Point (0,3).

3 = 0 + b

Answer:

Step-by-step explanation:

The measure of the angle is 48 degrees and the triangle BCD is isosceles.

What is a Circle?

A circle is a round-shaped figure with all the points on one plane, the distance between the center and all the points on the circumference is the same.

Thre arc mBC inscribes angle BDC

According to the theorem, the angle made by the arc on the center is double that made at the circumference.

mBDC = (1/2) * mBC

mBDC = (1/2) * 118 = 59°

It is also known from the secant theorem that, the angle made by the two secants is equal to half of the angle inscribing the arc.

mA = (1/2) * (mBC - mDE)

35 = (1/2) * (118 - mDE)

70 = 118 - mDE

The measure of DE = 48°

The sum of all the arcs in a circle is 360°

So,

mBC + mCD + mDE + mBE = 360

mCD = 360 - 118 - 48 - 76 = 118°

The angle CBD is inscribed by the arc mCD

mCBD = (1/2) * mCD = (1/2) * 118 = 59°

The angles CBD and BDC are equal, so the triangle is isosceles.

Answer:

(5,-3)

Step-by-step explanation:

If point A is 6.5 on the x axis away from point M, then point B must be the same distance away. -1.5+6.5=5. If point A is 4 on the y axis away from point M then point B must also be the same distance away. 1-4=-3.

khan

Answer:

55°

Step-by-step explanation:

In circle with center O, OA and OB are radii and PA and PB are tangents drawn from external point P.

Since, tangent is perpendicular to the radius of the circle.

[tex] \therefore m\angle PAO = m\angle PBO = 90°\\

m\angle APB = 70°....(GIVEN) \\[/tex]

In quadrilateral PAOB,

[tex] m\angle PAO + m\angle PBO+ m\angle APB \\+m\angle AOB = 360°\\

\therefore 90° + 90° + 70° +m\angle AOB = 360°\\

\therefore 250° +m\angle AOB = 360°\\

\therefore m\angle AOB = 360°- 250°\\

\huge \purple {\boxed {\therefore m\angle AOB = 110°}} \\[/tex]

Since, angle subtended at the circumference of the circle is half of the angle subtended at the centre of the circle.

[tex] \therefore m\angle ACB = \frac {1}{2} \times m\angle AOB\\\\

\therefore m\angle ACB = \frac {1}{2} \times 110°\\\\

Answer: 0.05%

Step-by-step explanation:

Ok, you have 5 tickets with different combinations of 4 numbers of them.

Now, the total number of combinations of 4 numbers (0 to 9) can be found as:

For the first number we have 10 options.

For the second number we also have 10 options.

for the third number we also have 10 options

for the fourth number we also have 10 options.

The total number of combinations is equal to the product of the number of options for each selection, this is:

Combinations = 10*10*10*10 = 100*100 = 10,000.

So out of 10,000 possible combinations, you have 5.

Then the odds of winning is the quotient between the combinations that you have and the total number of combinations: p = 5/10,000 = 0.0005

In percentage form, this is: 0.0005*100% = 0.05%

A handyman need 34 rows of 18 tiles.

How many total tiles does he need?

lets start off by saying that each row has 18 tiles

and there are supposed to be 34 rows

so you can multiply the number of tiles in each row (18) by the number of rows (34)

34 x 18 = 612

the handyman needs a total of 612 tiles to cover the floor.

2)

a.

46,900

3)

a.

84,500

4)

a.

12,000

Step-by-step explanation:

1) 1 mile = 5280 ft.

Area of both sides = 5280 ft × 8 ft × 2 sides = 84480 ft²

Since 1 person for each 4.5 square feet, the ratio of one person to 1 square feet = [tex]\frac{1}{4.5}[/tex]

the size of a crowd = [tex]\frac{1}{4.5} *84480=18773.33[/tex] ≈ 18700

2) 1 mile = 5280 ft, therefore 2 mile = 10560 ft (5280 × 2)

Area of both sides = 10560 ft × 10 ft × 2 sides = 211200 ft²

Since 1 person for each 4.5 square feet, the ratio of one person to 1 square feet = [tex]\frac{1}{4.5}[/tex]

the size of a crowd = [tex]\frac{1}{4.5} *211200=46933.33[/tex] ≈ 46900

3) 1 mile = 5280 ft, therefore 2 mile = 10560 ft (5280 × 2)

Area of both sides = 10560 ft × 10 ft × 2 sides = 211200 ft²

Since 1 person for each 2.5 square feet, the ratio of one person to 1 square feet = [tex]\frac{1}{2.5}[/tex]

the size of a crowd = [tex]\frac{1}{2.5} *211200=84400[/tex] ≈ 84500

4) 1 yard = 3 ft, therefore 100 yard = 300 ft (100 × 3)

Area of both sides = 300 ft × 50 ft × 2 sides = 30000 ft²

Since 1 person for each 2.5 square feet, the ratio of one person to 1 square feet = [tex]\frac{1}{2.5}[/tex]

the size of a crowd = [tex]\frac{1}{2.5} *30000=12000[/tex]

Answer:

EF, FG, AB and BC are perpendicular to BF.

Step-by-step explanation:

In the figure attached, a rectangular prism has been given.

Line BF is contained in the face BCGF of the prism.

Therefore, all the faces perpendicular to the face given are,

ABFE, EFGH, ABCD and CGHD.

But the line segments contained in these faces and perpendicular to the line segment BF are EF, FG, AB and BC.

Therefore, answer is the line segments EF, FG, AB and BC are perpendicular to BF.

Line segments perpendicular to BF are:

GF, EF, AB, and CB

Perpendicular lines are the two distinct lines that intersect at each other at 90°. A perpendicular is a straight line that makes an angle of 90° with another line. 90° is also called a right angle and is marked by a little square.

Given,

In figure ABCDEFGH is a rectangular prism

BF is an edge of the prism

All faces of the rectangular prism are perpendicular to each other

Face EFGH is perpendicular to face BCGF

⇒ GF⊥BF and EF⊥BF

Face ABCD is perpendicular to face BCGF

⇒ AB⊥BF and CB⊥BF

Hence, line segments GF, EF, AB, and CB are perpendicular to BF.
