Answer:

$1102.50

Step-by-step explanation:

The appropriate compound interest formula is

A = P(1 + r)^t, where P is the principal ($1000), t is the number of years, and r is the interest rate as a decimal fraction.

Here A = $1000(1 + 0.05)^2  =  $1000(1.05)^2 = $1102.50

Step-by-step explanation:

(x1,y1) = (-4,0)

(x2,y2) = (0,2)

(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)

(y - 0)/(2 - 0) = (x + 4)/(0 + 4)

y/2 = (x + 4)/4

4y = 2(x + 4)

2y = x + 4

y = x/2 + 2

Answer:

x=33 ; y=23

Step-by-step explanation:

Given that x+y=56 and x-y=10

Solve for either variable.

x=y+10

Substitute, replace, your solved variable in the other equation

(y+10)+y=56    Subtract 10 on both sides

2y=46     Divide by 2

y=23        Substitute answer into a given equation

x+23=56    Subtract 23 on both sides

x=33

Answer:

∠ A = 59°, ∠ B = 48° , ∠ C = 73°

Step-by-step explanation:

The interior angles of a triangle sum to 180°

sum the 3 angles and equate to 180

x + x - 11 + 73 = 180

2x + 62 = 180 ( subtract 62 from both sides )

2x = 118 ( divide both sides by 2 )

x = 59

Then

∠ A = x = 59°

∠ B = x - 11 = 59 - 11 = 48°

∠ C = 73°

Answer:

<A = 149*

<B = 138*

<C = 73*

Step-by-step explanation:

There are 360* total inside a triangle.

We subtract 73 from 360 to find the combined number of both angles a and b.

360-73 equals 287, so we know that both angles a and b add up to equal 287.

Since angle a equals x and angle b equals x - 11, we would combine the two expressions to find x. When we find x, it will allow us to know what both angles a and b equals to. So we combine x and x- 11, set it equal to 287, and solve for x.

x + x - 11 = 2x-11.

287 = 2x - 11

(Add eleven to both sides)

298 = 2x (divide both sides by two)

X = 149

Since angle a equals x, we know that angle a Is 149*.

And since angle b is x - 11, we take 149, subtract it by 11, and we get 138.

Answer:

Yes

hope this helps if not then sorry good luck and bye

Answer:

x = 72° , y = 54°

Step-by-step explanation:

x and 108° are adjacent angles on a straight line and sum to 180°

x + 108° = 180° ( subtract 108° from both sides )

x = 72°

The vertex of the triangle on the left is vertically opposite x and is congruent

vertex = 72°

The sum of the 3 angles in the triangle = 180° , that is

y + y + 72° = 180°

2y + 72° = 180° ( subtract 72° from both sides )

2y = 108° ( divide both sides by 2 )

y = 54°

Answer:

so the answer is y=54°

Step-by-step explanation:

that is my answer hope it helps

Step-by-step explanation:

Answer:

last year = 530570

this year = 424456

decreased plants = 530570-424456 = 106114

decreased percent = 106114÷530570×100%

= 20%

therefore 20% is the decrease precent in the number of potted plants ordered anually

The missing length of the given triangle divided into two right-angled triangle is 24.

The ratio 60:36:x is a ratio of 2:1:x. This means that the ratio of the lengths of the three segments is 2:1:x. The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.

Here is the solution in more detail:

The ratio 60:36:x can be written as 2:1:x.

This means that the ratio of the lengths of the three segments is 2:1:x.

The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.

Therefore, the missing length is 24.

The perimeter of triangle DEF is; 30 cm

We are given dimensions of Triangle ABC as;

Thus;

Perimeter of Triangle ABC = 9 + 6 + 7.5 = 22.5 cm

We are told that Triangle DEF is similar to Triangle ABC.

This means that the ratio of corresponding sides must be equal to the ratio of their perimeter.

Side EF corresponds to side BC. Thus;

Perimeter of Triangle DEF/22.5 = 8/6

Cross multiply to get;

Perimeter of Triangle DEF = (22.5 × 8)/6

Answer:

B) Graph B

Step-by-step explanation:

The quadratic equation in vertex form is represented by: y = a(x - h)² + k, where:

(h, k) = vertex

x = h : axis of symmetry

a = indicates a reflection in the x-axis; it also determines the graph's vertical stretch or shrink.

h =  indicates a horizontal translation.

k =  indicates a vertical translation.

Given the given quadratic equation, y = (x - 2)² - 16:

The vertex occurs at point, (2, -16), and a = 1. Since the value of a is positive, then it implies that the graph opens upward, and the vertex is its minimum point.  The axis of symmetry occurs at h = 2.

To determine another point to use as a reference (and also for graphing) is solving for the equation's y-intercept, which is the point where it crosses the y-axis (where x = 0).

Y-intercept: set x = 0:

y = (x - 2)² - 16

y = (0 - 2)² - 16

y = (-2)² - 16

y = 4 - 16

y = -12

Therefore, the y-intercept is (0, -12).

Therefore, the graph that matches these given descriptions is Graph B.    

Attached is the graphed quadratic equation where it shows the vertex, y-intercept, and the axis of symmetry.

Answer:

Cleo is: 25 years old

Range of their ages: 7 years

Step-by-step explanation:

Supposing that they are all around roughly the same age, say, Ahmed was 18 and Beth was 20. The mean/average, is taking both ages, and dividing it by how many people there were. Which was just two. So, 18+20=38. 38/2 gets you 19. To get Cleo's age, we would do,

18+20+ Cleo's age. to get a number, divide it by 3, and get 21. Saying that the mean/average is 21, he would definetly be older. So plug in ages. 24+20+18=62. 62/3 gets you 20.67. 25+20+18=63. 63/3 gets you 21. Therefore, he must be 25.

The range is calculated by subtracting the largest number, by the smallest number. And, given that the median, or, middle is 20, we can know that the previous answer is correct. 25-18 to get 7 as the range.
