Answer: Diana donates $125 each month.

Step-by-step explanation:

Let x = Amount of money Diana donates each month.

Money she donates in a year = 12x  [ 1 year = 12 months]

Given: Money she donates in a year = $1500

So, [tex]12x=1500\Rightarrow\ x=\dfrac{1500}{12}=\$125[/tex]

i.e. Amount of money Diana donates each month = $125

Hence, Diana donates $125 each month.

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:

(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

Option C is correct

Answer:

what is this pls isit a question

Answer:

y = -3x + 2

Step-by-step explanation:

y = mx + b

m is the slope and b is the y-intercept

So the slope is -3 as it's going down, down is negative, by 3 units and only going to the right one unit while doing so. The y-intercept is where the line is intercepting on the y-axis. So it's: y = -3x + 2

Answer:

−6x+12

Step-by-step explanation:

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.

(1, −8)

The result can be shown in multiple forms.

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:

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

Answer:

A

Step-by-step explanation:

if h(x)=(x/2)-6, find h(10)

What this means is that wherever there is an x on the right hand side, replace it with a 10

h(10) = (10/2) - 6

h(10) = 5 - 6

h(10) = -1

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.
