Area of big diagram = 33.32 m²

Step-by-step explanation:

Given:

Both given diagram is similar

Perimeter of small diagram = 20 m

Area of small diagram = 19.6 m²

Perimeter of big diagram = 34 m

Find:

Area of big diagram

Computation:

Both given diagram is similar So,

Perimeter of small diagram / Area of small diagram = Perimeter of big diagram / Area of big diagram

20 / 19.6 = 34 / Area of big diagram

Area of big diagram = [19.6/20][34]

Area of big diagram = 33.32 m²

Answer:

56.6

Step-by-step explanation:

this equation (34/20)^2 * 19.6 = 56.644

Bill plans to save for a pair of headphones that are 89.00.The sales tax rate is 8% how much will bill need to save

Answers

Answer: 96.12

Step-by-step explanation:

The amount that Bill will need to save will be for the cost of the headphones and the sales tax that will be applied. This will be:

= 89 + (8% × 89)

= 89 + (0.08 × 89)

= 89 + 7.12

= 96.12

Therefore, Bill will need to save 96.12.

Answers

Step-by-step explanation:

a. What is the total cost (startup fee and monthly charge) to use the cell phone plan for 1 month?

answer for a: $95 + $55 = $150

b. Is there a proportional relationship between time and the cost of the cell phone plan?

answer for b: There is a proportional relationship between time and the cost of the cell phone plan because each month of time that passes, your phone will be charged $55. We know this because every month of Han's cell phone plan costs $55.  

c. What is the total cost for x months? (Write an equation for the situation.)

answer for c: 95 + 55x = y

Answers

Number line can be found in the picture attached below

Answer:

The claim is incorrect ; Point S will be located to the left of Point P

2.5 > 1.25

Step-by-step explanation:

Location of point S = 5/4 = 1 1/4 = 1.25

From the number line ; location of point P = 2.5

Point S is lesser than P, therefore, point S would be located to the left of point P on the number line.

Inequality that describes the relationship between the value of point P and point S ;

Point P = 2.5 ; Point S = 1.25

Point P > Point S

Answers

Given:

The graph of a compound inequality is given.

To find:

The compound inequality.

Solution:

From the given graph it is clear that an arrow approaches towards left from [tex]x=-2[/tex] and there is an open circle at [tex]x=-2[/tex].

It means all the values less than [tex]-2[/tex] are included in the solution set but [tex]x=-2[/tex]  is not included.

[tex]x<-2[/tex]                  ...(i)

An arrow approaches towards right from [tex]x=4[/tex] and there is a closed circle at [tex]x=4[/tex].

It means all the values greater than of equal to 4 are included in the solution set and [tex]x=4[/tex] is also included.

[tex]x\geq 4[/tex]     ...(ii)

Using (i) and (ii), we get the compound inequality.

[tex]x<-2[/tex] or [tex]x\geq 4[/tex]

Therefore, the correct option is C.

100-38=62

MJL=62

angle(m)=80

Answer:

<MJL = 62°

<m = 80°

x = 4

Step-by-step explanation:

in ∆JKL total angle aum is 180° and to find <L we have to subtract the given angles in this triangle from 180

that is

<L = 180-80-38 = 62°

then <MJL = 62° (alternative interior angle)

<JLM= 38° (alternative interior angle)

then <m = 180-62-38 = 80°

Step-by-step explanation:

The number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain is 24m < 256

What is an inequality?

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Let m represent the number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain.

Hence:

(48/2)m < 256

24m < 256

The number of minutes Trina can run the water hose to add more water to the pond without adding the maximum amount in case of rain is 24m < 256

The changes is is the same amount of meat from Thursday to Friday is ___
Kilograms of meat

Answers

The rate of change  is the same amount of meat from Thursday to Friday is 14 Kilograms of meat

Here, the line graph shows the amount of meat in kilograms fed to the lions on each day of the week.

From the line graph the amount of meat fed to the lines on Thursday is 58 kilograms

And the amount of meat fed to the lines on Thursday is 72 kilograms

Let x represents the rate of change in the amount of meat from Thursday to Friday.

So, the value of x would be,

x = 72 - 58

x = 14 kilograms

Thus, the rate of change in the same amount of meat are fed to the alliance between Thursday and Friday = 14 kilograms

Given:

Macy has 8 quarters and 24 pennies in her pocket.

To find:

The answer that correctly shows the ratio of this comparison.

Solution:

We know that,

Number of quarters = 8

Number of pennies = 24

The ratio of this comparison is:

[tex]Ratio=\dfrac{Quarters}{Pennies}[/tex]

[tex]Ratio=\dfrac{8}{24}[/tex]
