which number is a multiple of 7

Answers

Answer:

7, 14, 21, 28, 35, 42, 49, 56, 63, 70...

Step-by-step explanation:

Determine if the sequence is arithmetic or geometric, and find the common difference or ratio.

x 1 2 3 4
f(x) 5 −5 −15 −25
Arithmetic, common difference = −10
Arithmetic, common difference = −1
Geometric, common ratio = −10
Geometric, common ratio = −1

Answers

Answer:

The sequence is arithmetic with a common difference of -10

Step-by-step explanation:

From the question, we want to determine if the sequence is arithmetic or geometric

From the question

f(1) = 5

f(2) = -5

f(3) = -15

Mathematically for the common difference;

f(3) - f(2) = f(2) - f(1)

Since;

-15-(-5) = -5-5

-10 = -10

Since the common difference here is same , then the sequence is arithmetic with a common difference of -10

Solve for H: A = L ⋅ W ⋅ H
H = A times W over L
H = W times L over A
H = L times A over W
H = A over quantity L times W

Answers

Answer:

The answer would be

H = A over L times W

Step-by-step explanation:

This is because, when you multiply the L, W, and H you end up getting A. This means that A is the biggest number. We automatically can tell that H is what were looking for so putting those two things together we have this: H = A over ???

The ??? would have to be L times W because those are the only things left and they get multiplied together which in the end leaves us with

H = A over L times w

aka

H=A/LxW

if you flip three coins, the probability of getting three heads is 1/8. Interpret this probability.

Answers

Suppose you have a fair coin: this means it has a 50% chance of landing heads up and a 50% chance of landing tails up. Suppose you flip it three times and these flips are independent. So the probability that it lands heads up, then tails up, then heads up is 1/8, or 12.5%.
(Also you can use the formula for that.

The interpretation of the probability is there is a 12.5% chance of obtaining three heads when three coins are flipped

The probability is given as:

[tex]\mathbf{Pr = \frac 18}[/tex]

The above represents the probability of flipping a head three times.

Express as decimal

[tex]\mathbf{Pr = 0.125}[/tex]

Express as percentage

[tex]\mathbf{Pr = 12.5\%}[/tex]

This means that, there is a 12.5% chance of obtaining three heads when three coins are flipped

Answers

Answer:

a) Angle XBC = 55⁰ because its correspond to Angle AXY which is equal to 55⁰ and corresponding angles are equal.

b)Angle BXC = 70⁰

Step-by-step explanation:

b) Since XB = XC, triangle BXC is therefore an isosceles triangle.

Angle XBC = Angle XCB

Sum of interior angles of a triangle = 180⁰

55⁰ + 55⁰ + Angle BXC = 180⁰

110⁰ + Angle BXC = 180⁰

Angle BXC = 180⁰- 110⁰

= 70⁰

What is the slope of a line parallel to the line whose equation is 5x+y=-9

Answers

Answer:

slope = - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c (m is the slope and c the y- intercept )

Given

5x + y = - 9 ( subtract 5x from both sides )

y = - 5x - 9 ← in slope- intercept form

with slope m = - 5

Parallel lines have equal slopes, thus

The slope of a parallel line to the given equation is m = - 5

Find the value of x
(9x-38)+(4x+23)=180

Answers

Answer:

x=15

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

9x−38+4x+23=180

9x+−38+4x+23=180

(9x+4x)+(−38+23)=180(Combine Like Terms)

13x+−15=180

13x−15=180

Step 2: Add 15 to both sides.

13x−15+15=180+15

13x=195

Step 3: Divide both sides by 13.

13x/13=195/13

Answer:

Step-by-step explanation:

9x-38+4+23=180

13x-15=180

13x=195

The length of a rectangle is twice the width. The area of the rectangle is 80 square units. Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square? Estimate the length and width of the rectangle.

Answers

Answer:

Width of the rectangle = 6.325 units

Length of the rectangle = 12.65 units

Side length of the square the 6.325 units.

Step-by-step explanation:

The length of a rectangle is twice the width. The area of the rectangle is 80 square units.

The area of the rectangle = Length × Width

Length = 2W

80 square units = 2W × W

80 = 2W²

W² = 80/2

W² = 40

W = √40

Width of the rectangle = 6.3245553203 units

Approximately = 6.325 units

Length = 2 × Width

= 2 × 6.325

= 12.65 units

• Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square?

We you divide a rectangle into 2 squares,

The length is divided into two.

Hence, the length of the rectangle = 12.65 units

12.65 units ÷ 2 = 6.325 units.

Hence, the side length of the square the 6.325 units.

The number of rectangles and combinations:

1 rectangle = 62 rectangles = 53 rectangles = 44 rectangles = 35 rectangles = 26 rectangles = 1

Total

6 + 5 + 4 + 3 + 2 + 1 = 21

Now the number of,

Rectangles and combinations are,

→ 1 rectangle = 6

→ 2 rectangles = 5

→ 3 rectangles = 4

→ 4 rectangles = 3

→ 5 rectangles = 2

→ 6 rectangles = 1

Then the total number is,

→ 6+5+4 + 3+2+1

→ 15 + 6 = 21

Hence, total number is 21.

1 pack of cigarettes contains 20 cigarettes. Each cigarette smoked is said to reduce a person's life expectancy by 11 minutes. If a person smoked one pack per day for 25 years, how much shorter would their life possibly be? In minutes: In days: In hours: In years: bruh, heaLP

Answers

Answer:

Step-by-step explanation:

1 pack per days means 20 cigarettes a days each cigarette reduces life by 11 minutes. which is 220mins per day

25*365*24*60 =13140000mins originally

1) 25 years in minutes will be

reduction of life due to smoking = 220*365*25= 2007500minutes

2)In days

originally = 9125days

after smoking=220/24*60=0.1527*365*25= 1393days are reduced

3)In hours

originally = 219000hrs

reduced life =3.67*365*25= 33488.75hrs
