Explain howto use friendly percents to find 35% of 80

Answer:

first option

Step-by-step explanation:

There is a common ratio r between consecutive terms in the sequence, that is

r = - 15 ÷ 3 = 75 ÷ - 15 = - 375 ÷ 75 = - 5

The recursive formula allows a term in the sequence to be found by multiplying the previous term by r , thus

f(n) = - 5f(n - 1) if n > 1

with f(1) = 3 ← first term

Answer:

D . f(n)=f(1)=3

            f(n)= -5f(n-1)if n >1

Answer:

  x - 18 = 21

Step-by-step explanation:

In math, the description, "the difference between p and q" is written as ...

  p - q

Then the difference between x and 18 is ...

  x - 18

When we say that "is 21", we mean it is equal to 21:

  x - 18 = 21

Since UV and VW make up UW, we can set add together UV and VW and set them equal to UW.

5x - 18 = 13 + 3x - 5

Let's combine like terms on the right side.

5x - 18 = 3x + 8

Subtract 3x from both sides and add 18 to both sides.

2x = 26

Divide both sides by 2

x = 13

We know that UW = 5x - 18. Let's plug 13 in for x.

UW = 5(13) - 18 = 65 - 18 = 47.

Answer:

5

Step-by-step explanation:

Step 1:

x - 2 = 3x - 12

Step 2:

- 2 = 2x - 12

Step 3:

10 = 2x

Step 4:

5 = x

We have a triangle whose perimeter is 32 feet. Some information regarding the sides of the triangle is given:

GiveN:

As we can see that, two sides of the triangle are defined the second sides. It means First and third side can be expressed in the form of second side.

Then,

We know that, perimeters is the sum of the lengths of all sides of the triangle, So it can be written as:

[tex]3x + x + x + 12 = 32[/tex]

Solving it further,

[tex]5x + 12 = 32[/tex]

Subtracting 12 from both sides,

[tex]5x + 12 - 12 = 32 - 12[/tex]

[tex]5x = 20[/tex]

Dividing 5 from both sides,

[tex] \frac{5x}{5} = \frac{20}{5} [/tex]

[tex]x = 4[/tex]

Then,

And we are done with the answer !!

Before multiplying two fractions together, always try to cross-cancel.

So in this problem, the 13 and 39 cross-cancel to 1 and 3.

So we have 1/15 × 11/3 which is 11/45.

Remember, multiply across the numerators and denominators.

Answer:

Step-by-step explanation:

did the calculations

The co-ordinates of point B is ( 10, 6 ).

A line segment is a subset of a line which has two endpoints.

According to the given question a  line segment AB has one endpoint at A(0, 0) which is (x₁,y₁)

Given midpoint is at (5,3).

Let B is (x₂,y₂).

We know midpoint of x is (x₁ + x₂)/2 and midpoint of y is (y₁ + y₂)/2.

∴ 5 = ( 0 + x₂ )/2

  5 = x₂/2

  x₂ = 10.

AND

3 = ( 0 + y₂ )/2

3 = y₂/2

y₂ = 6.

( x₂,y₂ ) = (10,6)

Answer: SW IS 1.5 OKKKKKKKKK

Answer:

He needs to sell an average of 3.5 items a day to reach his goal.

Step-by-step explanation:

To find the average he needs to sell, we need to divide the items he needs to sell by the number of days he has left to sell. He has 63 items and needs to sell them within 18 days.

63/18=3.5

He needs to sell an average of 3.5 items a day to reach his goal.

The salesman should sell 3.5 items on a daily average to reach his target when he needs to sell 63 items in 18 selling days.

The average is defined as the sum total of observations divided by the total number of observations.

In the question, we are informed that a salesman needs to sell 63 items to make it monthly within 18 selling days left in the month.

We are asked the average number of items he should sell daily to reach his goal.

The average number of items per day can be calculated as the ratio of the total number of items left to the total number of days left.

Therefore, the average number of items per day = 63/18 = 3.5.

Answer:

y = -x + 10 and y = 4x.

4x = -x+10

Step-by-step explanation:

To find the area of the larger figure, let's multiply the length by the width.

9 ft * 4 ft = 36ft^2

Let's do the same thing with the smaller figure.

3 ft * 4 ft = 12ft^2

Let's add the area of both figures together.

36ft^2 + 12ft^2 = 48ft^2

Answer:

The length of the longer side is 2√2/3

Step-by-step explanation:

A 45-45-90 triangle is a right-angled triangle.

In fact, since it has two angles equal, it is a right angled isosceles triangle. What we are saying is that two of its sides are equal.

Hence, we have two short sides which are the opposite and the adjacent and a longer side which is the hypotenuse

Thus, to find the length of the longer side, we employ Pythagoras’ theorem and it states that the square of the hypotenuse equals the sum of the squares of the two other sides;

Mathematically, let’s call the longer side x

so x^2 = (2/3)^2 + (2/3)^2

x^2 = 4/9 + 4/9

x^2 = 8/9

x = √(8/9)

x = 2√2/3

Answer:

38 and 40

Step-by-step explanation:

Hope this helps you :)

Answer:

39 would fall between 38 and 40

Step-by-step explanation:

Step-by-step explanation:

On the right side, 3 + 4 + 7 = 14, so the other two numbers must add up to 22.  Therefore, they must be 10 and 12.

Let's assume 12 is the top number and 10 is the bottom number.

The left side adds up to 12 + 9 + 2 = 23, so the other two numbers add up to 13.  Therefore, they must be 5 and 8.

The bottom side adds up to 10 + 1 + 11 = 22, so the other two numbers add up to 14.  Therefore, they must be 6 and 8.

So the bottom left number is 8.

Answer:

19 1/18 miles.

Step-by-step explanation:

For Tuesday's ride we need to multiply 10 8/9 by 3/4.

10 8/9 = (9*10+8) / 9 =  98/9 miles.

98 / 9  * 3/4

= 98/3 * 1/4

49/6

= 8 1/6 miles.

Total miles over 2 days = 10 8/9 + 8 1/6

= 18 + 8/9 + 1/6

= 18 +  48/54 + 9/54

= 18 57/54

= 19 3/54

= 19 1/18 miles.
