Answer:

a. $16

b. $26

Step-by-step explanation:

a. 6+2(5)= 16

b. im assuming tt means ten 6+2(10)=26

If Audrey leaves her car in the lot for "t" hours, she would have to pay a total of $6 + $2t for parking.

If Audrey leaves her car in the parking lot for 5 hours, she will have to pay the initial fee of $6 plus $2 for each hour she parked. For 5 hours, she will pay:

Initial fee: $6

Additional fee for 5 hours: $2 * 5 = $10

Total parking cost: $6 + $10 = $16

If Audrey leaves her car in the parking lot for "t" hours, the total parking cost can be calculated as:

Total parking cost = Initial fee + Additional fee for "t" hours

Total parking cost = $6 + $2t

So, if Audrey leaves her car in the lot for "t" hours, she would have to pay a total of $6 + $2t for parking.

The first angle is 33.8° and second angle is 56.2°.

If the sum of the two angles is equal to the measurement of a right angle then the pair of angles is said to be complementary angles.

Complementary angles are the angles whose sum makes 90⁰.

Let's say our first angle is x:

x = first angle

According to the question,

The other angle is 22.4° more than the complementary angle.

Therefore, 22.4° will be added to the other angle.

first angle  = x

second angle = x + 22.4°

Since, complementary angle is equal to the sum of the two angles to be 90°.

∴ x + x + 22.4°  = 90°

    2x = 90 ° - 22.4°

    2x = 67.6°

     x = 67.6° / 2

     x = 33.8°

Thus, the first angle is 33.8° and second angle is 56.2°.

Answer: 2

Step-by-step explanation:

By the angle bisector theorem,

[tex]\frac{8}{24}=\frac{DC}{6}\\\\DC=2[/tex]

The length of DC is 2

Angle bisector theorem states that an angle bisector of a triangle divides the opposite side into two segments that are proportional to the other two sides of the triangle.

Given:

AB = 24, AC = 8, and BD = 6

Now, using angle bisector theorem

AB/ AC = BD / DC

24 / 8 = 6 / DC

Answer:

168 kg oats and 252 kg corn

Step-by-step explanation:

2 equations and 2 unknowns

eq 1: x + y = 420

x is the amount of oats

y is amount of corn

eq 2: 9.4x + 3.4y = 5.8*420

solve equation 1 for x

x = 420 - y

substitute the value of x in eq 2

9.4(420-y) + 3.4y = 2436

y = 252

substitute y in eq 1

x + 252 = 420

Answer:

a. The equation should be

4x + 3y = $11.67

8x + y = $12.89

b. The price of one can of soup and the price of one loaf of bread is $1.355 and $2.09

The calculation is as follows:

here we assume the soup be x and bread be y

So, the equations are

4x + 3y = $11.67 .........(1)

8x + y = $12.89.........(2)

Here we need to multiply by 2 in equation 1

8x + 6x = $23.34

8x + y = $12.89

5y = $10.45

y = $2.09

Now x should be

8($2.09) + y = $12.89

x = $1.355

Khalil: 4s + 1b = 11.67

Ronda: 8s + 1b = 12.89

B)

Can of soup = $0.305

Loaf of Bread = $10.45

(Please mark brainliest)

Step-by-step explanation:

Make s a can of soup

Make b a loaf of bread

A)

Khalil: 4s + 1b = 11.67

Ronda: 8s + 1b = 12.89

B)

12.89 - 11.67 = 1.22

1.22 / 4 = 0.305

11.67 - 1.22 = 10.45

Can of soup = $0.305

Solving a system of equations, we will see that Nora bought 2 apples and 6 bananas.

Let's define the variables:

We know that She buys 3 times as many bananas as apples.

y = 3*x

The total cost is $5.

x*$1 + y*$0.50 = $5

Then we have a system of equations:

y = 3*x

x*$1 + y*$0.50 = $5

Replacing the first equation into the second one we get:

x*$1 + (3x)*$0.50 = $5

Now we can solve this for x.

x*$1 + x*$1.50 = $5

x*$2.50 = $5

x = $5/$2.50 = 2

So She bought 2 apples, and:

y = 3*x = 3*2 = 6

Answer:

-2

Step-by-step explanation:

The amount Aisha would pay to paint her living room is £38.50.

The first step is to determine the area of the walls that do not have doors.

Area of a wall = length x width

3 x (2.6 x 3.5) = 27.30 m²

Dimensions of the wall with the door : (2.6m - 2.2m) x (3.5 - 0.8) = 0.4m x 2.7m

Area of the wall with the door : 0.4m x 2.7m = 1.08 m²

Total area of the walls: 27.30 m² +  1.08 m² = 28.38 m²

Number of paint tins needed for the walls : 28.38 / 8 = 3.55 = 4 tins

Cost of the paint tins : (11 x 3) + (0.5 x 11) = £38.50

The equations of the perpendicular lines are: y = 1/2x + 6, y = 15, y = -x - 2, y = 6x + 3 and y = 1/3x - 4

When a linear equation is represented as:

Ax + By = C

The slope (m) is:

m = -A/B

When the linear equation is represented as:

y = mx + c

The slope is m

A line perpendicular to a linear equation that has a slope of m would have a slope of -1/m

Using the above highlights, the equations of the lines are:

6. y = -2x + 5; (2, 7)

The slope is:

m = -2

The perpendicular slope is:

n = 1/2

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 1/2(x - 2) + 7

Evaluate

y = 1/2x - 1 + 7

This gives

y = 1/2x + 6

7. y = -5; (11, 15)

The slope is:

m = 0

The perpendicular slope is:

n = 1/0 = undefined

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 15

8. Graph ; (-12, 10)

The slope is:

m = (y2 - y1)/(x2 - x1)

Using the points on the graph, we have:

m = (2 - 3)/(3 - 4)

m = 1

The perpendicular slope is:

n = -1

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = -1(x + 12) + 10

y = -x - 12 + 10

Evaluate

y = -x - 2

9. y = -1/6x + 1; (-2, -9)

The slope is:

m = -1/6

The perpendicular slope is:

n = 6

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 6(x + 2) - 9

Evaluate

y = 6x + 12 - 9

This gives

y = 6x + 3

10. 6x + 2y = 14; (12, 0)

The slope is:

m = -6/2

m = -3

The perpendicular slope is:

n = 1/3

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 1/3(x - 12) + 0

Evaluate

y = 1/3x - 4
