Answer:

The cost of screen for window = 864.

Step-by-step explanation:

We have,

Fir solving,

★Conversion from ft to inches:

We kow that,

Taking this in mind, convert the values

= Length = 3 ft

= Length = 3 × 12

= Length = 36 inchees

= Breadth = 2ft

= Breadth = 2 × 12

= Breadth = 24 inches

★Area of window:

We know that,

= Area of rectangle = Length × Breadth

= Area = 36 × 24

= Area = 864 inches²

As, area of window in square inches equal to cost of the screen.

Therfore, cost of screen would be 864.

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = A(4, 6) and (x₂, y₂ ) = B(4, 3)

m = [tex]\frac{3-6}{4-4}[/tex] = [tex]\frac{-3}{0}[/tex]

Division by zero is undefined thus the slope of CD is undefined

Answer: The height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.

Step-by-step explanation:

Let x= height of each fir tree, y = height of each pine tree.

As per given, we have

x+y = 21          (i)

4x=y+24        (ii)

From (ii),

[tex]4x-y=24[/tex]            (iii)

Add (i) and (iii), we get

[tex]5x=45\\\\\Rightarrow\ x=\dfrac{45}{5}\\\\\Rightarrow\ x=9[/tex]

Put value of x in (i), we get

[tex]9+y=21\Rightarrow y=12[/tex]

Hence, the height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.

Answer:

Each fir tree is  9  meters tall and each pine tree is  12  meters tall.

Step-by-step explanation:

$9436 EMI Keri has to pay for $500,000 loan at the rate of 5% for 5 years.

equated monthly instalment or EMI relates to payments made regularly to repay an outstanding loan within a certain time frame.

Given loan rate is 5% and time period is 5 years let total amount is $500,000. Formula for EMI Calculation is -

P x R x (1+R)^N / [(1+R)^N-1] where-

P = Principal loan amount.

N = Loan tenure in months.

R = Monthly interest rate.

R = Annual Rate of interest/12/100.

Putting these values in above equation

EMI = 500000 *5* *(1 + 5%)^60 / [(1 + 5%)^60]

EMI = 9436

Therefore, Keri must pay a $9436 EMI on her $500,000 loan over five years at a rate of 5%

Answer:

113 miles

Step-by-step explanation:

Distance = 180 km

Number of km per mile = (8/5) = 1.6 miles

Number of miles between the schools:

Distance / Number of kilometers per mile

180km / 1.6

= 112.5 miles

= 113 miles

Distance between the schools is approximately 113 miles

Answer:

Hence a = 3.66 and -3.628

b = 0.834 and -2.634

Step-by-step explanation:

Given the equations

a-2b =2 -------- (1)

a²+b²+2a -3b =19 --------(2).

From 1;

a = 2 + 2b

Substitute into 2

(2+2b)²+b²+2a -3b =19

Expand

4 + 8b + 4b²+b²+2(2+2b)-3b = 19

4b²+b²+8b+4b+4+4-3b = 19

5b²+9b+8 = 19

5b²+9b-11 = 0

b = -9±√81+4(55)/2(5)

b= -9±√301/10

b = -9+17.34/10 and -9-17.34/10

b = 8.34/10 and -26.34/10

b = 0.834 and -2.634

Since a = 2+2b

a = 2+2(0.834)

a= 2 +1.668

a = 3.668

Also

a = 2+2(-2.634)

a = 2 - 5.628

a = -3.628

Hence a = 3.66 and -3.628

b = 0.834 and -2.634

Answer:

y = - 3x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (0, - 2) ← 2 points on the line

m = [tex]\frac{-2-4}{0+2}[/tex] = [tex]\frac{-6}{2}[/tex] = - 3

The line crosses the y- axis at (0, - 2 ) ⇒ b = - 2

y = - 3x - 2 ← equation of line

Answer:

We know it's at -1260 feet and descends 5 per minute

The expression of this would be: -1260 - 5x, where x would be the time in minutes, as from -1260 feets it descends 5 per min.

Then, if we need to calculate it when it passes 12 minutes, we can replace the x by 12, and get the distance it would be

-1260 -5*12 = -1320 feet

And the answer would be -1320 feets

Answer:

23

Step-by-step explanation:

Angle x and the two given angles form a triangle. The interior angles of a triangle add up to be 180.

so

[tex]124 + 33 + x = 180[/tex]

[tex]157 + x = 180[/tex]

[tex]x = 23[/tex]

In the parallelogram below, the value of x is [tex]23^o[/tex] using the angle sum property .

The angle sum property states that:

The sum of all the interior angles of a triangle is [tex]180^o[/tex].

A  parallelogram is a four sided figure in which opposite sides are equal and parallel.

Given that:

A parallelogram in which the measurement [tex]124^o[/tex] and [tex]33^o[/tex] is given.

The parallelogram is divided into two triangles.

The value of x can be calculated as:

[tex]x+ 33^o + 124^o = 180^o[/tex] (Angle sum property)

[tex]157^o +x = 180^o[/tex]

    x =[tex]180^o- 157^o[/tex]

    x = [tex]23^o[/tex]

Thus, the value of x is [tex]23^o[/tex].

Answer: 15% I think

Step-by-step explanation:

The percent of increase in the amount of shampoo the new bottle contains is 25%.

Given that, a certain brand of shampoo contains 12 ounces in a bottle and the new type of bottle contains 15 ounces of shampoo.

Percentage increase is the difference between the final value and the initial value, expressed in the form of a percentage.

Percentage increase = (Final value - Initial value) / Initial value × 100

Now, initial value = 12 and final value = 15

Percentage increase = (15-12)/12 × 100

= 3/12 × 100

= 1/4 × 100

=25%

Therefore, the percent of increase in the amount of shampoo the new bottle contains is 25%.
