Which expression best estimates

Answer:

(C)85.56 cm², 12.4 cm

Step-by-step explanation:

The Area of the screen of the new phone is :

19.68cm² + Area of the current phone screen size

The current phone screen size has dimensions: 6.1 cm and 10.8 cm,

Area of the current phone screen size = 6.1 cm × 10.8cm

Area of the current phone screen size = 65.88 cm²

Hence, The Area of the screen of the new phone is :

19.68cm² + Area of the current phone screen size

= 19.68cm² + 65.88cm²

= 85.56 cm²

The new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and ___

The is calculated as:

85.56cm²/6.9cm

= 12.4cm

Therefore, the new phone screen must have an area of 85.56cm², which is the product of 6.9 cm and 12.4cm

Answer: x = 8

Step-by-step explanation: 8x +36 = 5x + 60

                                               8x - 5x = 60-36

                                                3x = 24

                                                   x = 24/3

                                                  x = 8

Answer:

8.5

Step-by-step explanation:

Our current equation is:

x2 + 3x.

Let's replace all the x with 1.7.

1.7(2) + 3(1.7)

Let's solve this new equation normally, as if the 1.7 was always there.

1.7(2) = 3.4

3(1.7) = 5.1

Now, let's add both the products.

5.1 + 3.4 = 8.7

Therefore, we can conclude the answer is 8.7.

Answer: 33.3%

Step-by-step explanation:

Cost price of the car = $13500

Value of car one year later = $9000

Decrease in value of car = $13500 - $9000 = $4500

The percent of decrease of the value of the car will then be:

= Decrease in value of car / Cost price × 100

= $4500 / $13500 × 100

= 1/3 × 100

= 33.3 %

Answer:

t=6

Step-by-step explanation:

Solve for tt by simplifying both sides of the equation, then isolating the variable.

Answer:

t=6

Step-by-step explanation:

We first use the addition property of equality by adding 8 to both sides. This cancels out the "-8" on the left-hand side of the equation.

We get: 1/3t= 2.

Then, we multiply 3 to both sides of the equation to cancel out the fraction on the left-hand side of the equation.

We get: t=6

This is your final answer.

Answer:

200 students must agree to attend in order for the school to have the festival.

Step-by-step explanation:

200 is 40% of 500. We can also use fractions to figure this out.

[tex]\frac{40}{100} =\frac{x}{500}[/tex]

For 100 to become 500 it must be multiplied by 5. And whatever we do to the denominator we have to do to the numerator. So we multiply 40 × 5 = x

x = 200

[tex]\frac{40*5}{100*5} = \frac{x}{500}[/tex]      

[tex]\frac{40}{100} =\frac{200}{500}[/tex]

Answer:

(1, -8)

Step-by-step explanation:

Solve by Substitution

9x − y = 17 and 5x + 4y = −27

Solve for y in the first equation.

y = −17 + 9x 5x + 4y = −27

Replace all occurrences of y with −17 + 9x in each equation.

Replace all occurrences of y in 5x + 4y = −27 with −17 + 9x. 5x + 4 (−17 + 9x) = −27

y = −17 + 9x

Simplify 5x + 4 (−17 + 9x).

41x − 68 = −27 y = −17 + 9x

Solve for x in the first equation.

Move all terms not containing x to the right side of the equation.

41x = 41

y = −17 + 9x

Divide each term by 41 and simplify.

x = 1

y = −17 + 9x

Replace all occurrences of x with 1 in each equation.

Replace all occurrences of x in y = −17 + 9x with 1. y = −17 + 9 (1)

x = 1

Simplify −17 + 9 (1).

y = −8

x = 1

The solution to the system is the complete set of ordered pairs that are valid solutions.

The range of values for the length third side is (13 < SU < 52) Which is correct option (C).

Inequality is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is not equal.

In triangle Δ STU,

Side ST = 52,

And Side TU = 39.

Let missing side is smallest than other sides,

According to the sides of a triangle rule asserts that,

The sum of the lengths of any two sides of a triangle has to be greater than the length of the third side. The sum of the lengths of the two shortest sides TU and Side SU. That length is greater than the length of the longest side ST.

So, Side ST < Side SU + Side TU  

⇒  52 < Side SU + 39

⇒  52 - 39 < Side SU

⇒  13 < Side SU  

Since, Side ST is largest side So Side SU can not be greater than 52

Therefore, the range of values for the length side SU :

⇒ 13 < Side SU < 55

Hence, the range of values for the length third side is (13 < SU < 52).

Answer:

The total employee of the company is 11912

Step-by-step explanation:

The employee in one country = 27,100

Let the total population be P

[tex]\frac{ 22.6}{100} *P = 27,100[/tex]

P = [tex]\frac{27100*100}{22.6}[/tex]

P = 11911.5

P = 11912 (approximately)

So the total employee of the company is 11912
