Answer:

A = 40°

B = 50°

Step-by-step explanation:

If cos A = sin B, then A + B = 90

So, 2x/3 + 20  + 2x - 10 = 90

      2x + 60 + 6x - 30 = 270

               8x + 30 = 270

                       8x = 240

                          x = 30

2x/3 + 20 = 60/3 + 20 = 20 + 20 = 40

2x - 10 = 2(30) - 10 = 60 - 10 = 50  or  90 - 40 = 50

Answer:

The equation that models the situation is [tex]A(t) = 13(1.0078)^t[/tex]

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

[tex]A(t) = A(0)(1+r)^t[/tex]

In which A(0) is the starting value and r is the growth rate, as a decimal.

Starting value of 13 and a growth rate of 0.78%.

This means that [tex]A(0) = 13, r = 0.0078[/tex]

Write an equation to model the situation.

[tex]A(t) = A(0)(1+r)^t[/tex]

[tex]A(t) = 13(1+0.0078)^t[/tex]

[tex]A(t) = 13(1.0078)^t[/tex]

The equation that models the situation is [tex]A(t) = 13(1.0078)^t[/tex]

Answer:

Decagon

Step-by-step explanation:

Since the interior angle is 144 degree, each exterior angle is 180 - 144 = 36 degrees.

For any convex polygon (in particularly, for any regular polygon) the sum of exterior angles is 360 degrees.

Hence, the number of sides = the number of vertices = 360/36 = 10.

Answer. Your polygon is decagon with 10 sides (vertices).

Answer:

Step-by-step explanation:

According to question, we know that

His Sister has "1/5*$25 which is equal to $5, and his father has "40%*$25 which is equal to 0.4 * $25 = $10". So, the money Hafiz, his sister and his father have in total

= $25+$5+$10 = $40

Hafiz = $25

Sister = [tex]\frac{1}{5}[/tex]

Father = 40%

Total money of Hafiz, Sister, and Father altogether.

[tex]\frac{1}{5} X[/tex] $25

= $5

40% (0.4) x $25

= $ 10

$ 25 + $ 5 + $ 10

oki! Mizuki is here to help!

The answer is 61 cars!

Step-by-step explanation:

First, let's find how much money she needs to earn!

105 + 500 = 605

Then, we will divide the amount she needs to earn by the amount per each car!

605 ÷ 10 = 60.5

We get 60.5 As an answer but... since we must wash a whole car, we will round it up and get 61 cars as the answer!

The edge of a block of metamaterial is 10 centimeters.

The surface area of the cube all six faces of the cube are made up of squares of the same dimensions then the total surface area of the cube will be the surface area of one face added six times to itself. The formula to find the surface area of a cube is 6a², where a is edge.

Given that, a block of metamaterial is in the shape of a cube with a surface area of 600 square centimeters.

Here, 6a²=600

a²=100

a=10 centimeters

Therefore, the edge of a block of metamaterial is 10 centimeters.

Answer:

Janelle's height is 82 units.

Step-by-step explanation:

Let j represent Janelle's height.

It is mentioned that, 58 is the difference between Janelle's height and 24.

Mathematically, we can write it as :

j-24 = 58

We can solve it as follows :

Adding 24 both sides,

j-24+24 = 58+24

j = 82

Hence, Janelle's height is 82 units.

There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.

Logical or deductive reasoning involves using a given set of facts or data to deduce other facts by reasoning logically.

Given that, Last Saturday, an accident caused a traffic jam 13 miles long on a stretch of the interstate.

13 miles = 68,640 feet

One car is of 15 ft

Let there be x cars,

15x = 68,640

x = 4576

Therefore,  there are 4576 cars in traffic.

If there are more SUVs and trucks, their length will be more than a car and which will make less number of vehicles involved in the traffic.

Hence, There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.

Answer:

Part A: 4,300 ≥ 2500 + 0.12s

Part B: Less than or equal to $15,000

Part C: In the image

Step-by-step explanation:

For Part A: The total needs to be at least 4,300. So 4,300 is greater than or equal to how much she earns. 2,500 is the base pay, and it is added to 0.12s, which represents 12% of sales (s).

For Part B:

Using the inequality, solve for s

4,300 ≥ 2500 + 0.12s

Subtract 2500 from both sides

1800 ≥ 0.12s

Now divide both sides by 0.12 to isolate s

15000 ≥ s

So sales must be less than or equal to 15000.

36

Answer:

The answer is 36

When finding a percentage you would typically multiply the decimal. Example 20% of 100. Multiply 100 x 0.20 = 20

When trying to do the opposite you would do the inverse (opposite) operation. So the inverse (opposite) operation of mulitplication is division.

Example: 20% of what number w is 20? Divide 20/0.20 = 100

Okay now lets solve your problem!

25% of what number w is 9? Divide  9/0.25 = 36

Step-by-step explanation:

25% in decimal is 0.25

9 / 0.24 = 36

On solving the provided question, we can say that - the perimeter chest won't fit next to her bed, thus the answer is no.

The perimeter of a form is determined by the length of its contour. A rectangle or square's perimeter is determined by adding the widths of its four sides. In this instance, the rectangle's length and breadth are represented by x and y, respectively. The surface of a form is used to compute its area.

Given here is: In her room, it is 86 inches wide. The width of the bed is 76 inches.

She also wants to accommodate a chest of drawers that is 72 centimeters broad, which equals inches.

=> 90 cm = 24.6546536565 inches

and the space left in her room = 86-76=10 inches

thus, the chest will not fit next to her bed
