The linear equations of the lines are y = 1/3x and y = 4x + 17, respectively

The parallel line

The equation is given a

x - 3y = 9

So, we have

3y = x - 9

y = x/3 - 3

Slope = 1/3

The slopes of parallel lines are equal

So, the slope of the required line is 1/3

The equation is then calculated as

Using the points, we have

2 = 1/3 * 6 + c

c = 0

So, we have

y = 1/3x

The perpendicular line

The equation is given a

y + 1/4x - 5 = 0

So, we have

y = -1/4x + 5

Slope = -1/4

The slopes of parallel lines are opposite reciprocals

So, the slope of the required line is 4

The equation is then calculated as

y = mx + c

So, we have

y = 4x + c

Using the points, we have

5 = 4(-3) + c

The surface area of the triangular prism is 191 cm².

The surface area (SA) of a triangular prism is given by the formula:

SA = 2A + Ph

where A is the area of the base, P is the perimeter of the base, and h is the height of the prism.

First, we need to find the area of the triangular base.

Using the formula for the area of a triangle:

A = (1/2)bh = (1/2)(5 cm)(4 cm) = 10 square centimeter

Next, we need to find the perimeter of the base:

P = 5 cm + 6 cm + 8 cm = 19 cm

Now we can use the formula for the surface area of a triangular prism:

SA = 2A + Ph

= 2(10 cm²) + (19 cm)(9 cm)

= 20 cm²+ 171 cm²

= 191 cm²

Therefore, the surface area of the triangular prism is 191 cm².

The perimeter of a square is 56 M the area of rectangle is 8 square metre less than the area of the given figure square if the length of the rectangle is 16 m then breadth is 11.75 m

The perimeter of square = ( 4 ) ( side )

( 4 ) ( side ) = 56

side = 56 ÷ 4

side = 14 m

The area of the of the rectangle is 8m² less than the area of the square

Area of the square = ( side )²

Area = ( 14 )²

Area = 196 m²

Now, the area of the rectangle = ( length ) × ( breadth )

Area = 196 - 8

Area= 188 m²

Answer:

To determine whose mix will be more watery, we need to calculate the percent of water in each mix.

For Cameron's mix, the total amount of liquid (water + lemon mix) is 3 cups + 2 cups = 5 cups. The percent of water in the mix is (3/5) x 100% = 60%.

For Sophie's mix, the total amount of liquid is 9 cups + 4 cups = 13 cups. The percent of water in the mix is (9/13) x 100% ≈ 69%.

Therefore, Sophie's lemonade will be more watery.

Answer:Sophie mix is more watery

Step-by-step explanation:Cameron—->3 cups water and 2 cups lemon

Sophie——>9 cups water and 4 cups lemon

Cameron = 3/(3+2)*100=60%

Sophie=9/9+4*100=9.*7.5=69.2%

Hence Sophie uses more water

Answer:

6.4

Step-by-step explanation:

First add 10 to 22 to get 32

Then divide 32 by 5 to get x

The total number of people in attendance was 400 people in total.

Let:

x be the no of grandparents

y be the no of parents

z be the no of children

Since there are 400 people total, so we can write the equation:

x + y + z = 400

We also know that there were twice as many parents as grandparents, so we can write the equation:

y = 2x

We know that there were 50 more children than parents, so we can write the equation:

z = y + 50

Now we have a system of three equations with three variables:

x + y + z = 400

y = 2x

z = y + 50

We can solve this system using substitution method

First, we can use the second equation to express y in terms of x:

y = 2x

Next, we can use the third equation to express z in terms of x:

z = y + 50

z = 2x + 50

Now we can substitute these expressions for y and z into the first equation:

x + y + z = 400

x + (2x) + (2x + 50) = 400

5x + 50 = 400

5x = 350

x = 70

So there were 70 grandparents in attendance.

Using the second equation, we can find the number of parents:

y = 2x

y = 2(70)

y = 140

So there were 140 parents in attendance.

Using the third equation, we can find the number of children:

z = y + 50

z = 140 + 50

z = 190

So there were 190 children in attendance.

Therefore, the total number of people in attendance was:

70 grandparents + 140 parents + 190 children = 400 people in total.

f(2) = 0.172.

The function for this problem is defined as follows:

f(x) = 14/[3 + ae^(kx)]

When x = 0, y = 2, hence we can obtain the coefficient a as follows:

2 = 14/(3 + a)

6 + a = 14

a = 8.

Hence:

f(x) = 14/[3 + 8e^(kx)]

When x = 1, y = 1/2, hence the coefficient k is given as follows:

0.5 = 14/(3 + 8e^k)

1.5 + 4e^k = 14

4e^k = 12.5

e^k = 12.5/4

k = ln(12.5/4)

k = 1.14.

Hence:

f(x) = 14/[3 + 8e^(1.14x)]

The maximum amount that you should finance is $26701 (rounded to the nearest dollar).

We can use the formula for monthly payments on a loan:

PMT = (PV x r x (1 + r)ⁿ) / ((1 + r)ⁿ - 1)

where PMT is the monthly payment, PV is the principal amount (the amount financed), r is the monthly interest rate, and n is the total number of months.

We can rearrange this formula to solve for PV:

PMT = (PV x r x (1 + r)ⁿ) / ((1 + r)ⁿ - 1)

Substituting the given values:

PMT = $499

r = 4.6% / 12 = 0.0038333 (monthly interest rate)

n = 5 x 12 = 60 (total number of months)

We get:

PV = $499 x ((1 + 0.0038333)⁶⁰- 1) / (0.0038333 x (1 + 0.0038333)⁶⁰)

The measures of the three angles are 30°, 86° and 64°.

Given that, in a triangle the sum of the measures of the second and third angles is five times the measure of the first angle.

The third angle is 22 more than the second.

If x, y, and z represent the measures of the first, second, and third angles, respectively, we need to find the measure of the angles.

So,

y + z = 5x...........(i)

z - y = 22...........(ii)

x + y + z = 180...........(iii)

Use eq(i) in eq(ii)

x + 5x = 180

6x = 180

x = 30°

Put x = 30 in eq(iii)

z + y = 150.......(iv)

add eq(ii) and eq(iv)

2z = 172

z = 86°

Put the values of z and x in eq(iii)
