Answer:

One end of the ladder rests at 8 feet on the wall.

Step-by-step explanation:

In the figure attached,

AC is a ladder 10 feet long leaning against the wall.

Distance of it's one end from the wall = 6 feet

Let the ladder rests on the wall at the height = h feet

By applying Pythagoras theorem in ΔABC,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

AC² = AB² + BC²

(10)² = h² + 6²

h² = 100 - 36

h = √64

h = 8 feet

Therefore, one end of the ladder rests at 8 feet on the wall.

Answer:

1) 60 m³ 2)182 m³ 3) 456 in.³

Step-by-step explanation:

1) 3 x 6 x 3 = 54

1 x 2 x 3 = 6

54 + 6 = 60

2) 3 x 6 x 7 = 126

2 x 7 x 4 = 56

126 + 56 = 182

3) 3 x 4 x 2 = 24

9 x 4 x 12 = 432

24 + 432 = 456

Answer: 30 m2

Step-by-step explanation:

The area of the pool is 40 m2 and the area of the walk way (before) is 70 m2.

70 - 40 = 30 m2

Answer:

In the equation 9 X 3 = 27, each factor stands for:

Step-by-step explanation:

When you must know the area of a terrain or figure, you must know what is the form of that (circle, triangle, rectangle, square, or another figure), because, with this, you can use different formulas of the area, in the case given in the exercise, the formula used is to a rectangle (is the same that a square, but how the length and the width aren't equal, is a rectangle), knowing this the formula is:

In a rectangle, the length is bigger than the width, by this reason 9 is the length, 3 the width and the result is the area, how you can see below:

Answer: 2560000

Step-by-step explanation:

Given, A worker needs to create a 4-character password.

Worker can use :

Alphabets, numbers and 4 special characters

Total alphabets = 26

Total digits = 10

So, total characters he can use = 26(alphabets) + 10 (digits) +4 (special characters)

= 26+10+4 = 40

Since, there is no pattern or condition is provided to choose them.

So, the total possible outcomes to create a 4-character password. = [tex](\text{Total characters})^4=40^4=2560000[/tex]

Hence, the total possible outcomes = 2560000

Answer:

The correct answer is -4

Step-by-step explanation:

First you have to solve what is in the parenthesis. So do 36/6 which is 6 and then subtract 2 to get 4. Then you have to do the multiplication so 16 x 4 and you get 64. then you can go left to right. 82-64+18+4 and when you do that you get -4

Answer:

a. -3x = -2y

When x=6, y=9

Step-by-step explanation:

From the hanger, There are two sides

If x=triangle and y=square

First side has 1 triangle and 3 squares

It can be represented by

x+3y

Second side has 4 triangles and 1 square

It can be represented by

4x+y

Equate the first and second side

x+3y=4x+y

Collect like terms

x+3y-4x-y=0

-3x+2y=0

-3x=-2y

Find y when x=6

-3(6)=-2y

-18=-2y

Divide both sides by -2

-18/-2=-2y/-2

9=y

y=9

The value of y when x = 6 is 9

Given that the weight of the triangle is x and the weight of the square is y.

For the hanger at the left, the resulting equation will be:

x + 3y (1 triangle and 3 square)

For the right-hand side

4x + y (4 triangles and 1 square)

Equating both expressions

x + 3y = 4x + y

x - 4x = -2y

-3x = -2y

3x = 2y

If x = 6, hence;

3(6) = 2y

2y = 18

y = 9

Hence the value of y when x = 6 is 9

Answer: 112

2x+3x+10=180

5x=170

x=34

3x+10=112

The measure of the largest angle in the diagram is 112 degrees.

An angle is formed when two straight lines or rays meet at a common endpoint.

The sum of two angles is 180 degrees when they are complementary.

2x+3x+10=180

Two times of x plus three times of x plus ten equal to one hundred eighty.

5x+10=180

Five times of x plus ten equal to one hundred eighty.

Subtract 10 from both the sides

5x=170

Divide both sides by 5

x=34

Now substitute x value in 3x+10 which is largest angle.

3(34)+10

102+10

112

Hence,  the measure of the largest angle in the diagram is 112 degrees.

Answer:

109.2

Step-by-step explanation:

If the number being divided does not end in 5 or 0, it being divided by 5 will not be equal. Therefor it might be better to try and use a calculator if you can't do it in your head.

Explanation:

First lets do the long division method. First we need to fit 5 into 5. That would be 1. So we write a 1 above the 546. Then we need to fit 5 into 4. Well it doesn't fit so we write a zero move another number. How many 5s fit into 46 well that would be 9. All we have left is a remainder of 1 which cannot fit into 5 and there are no more numbers

If you want a decimal that would be 109.2 or 109 1/5

Answer:

62 cm

Step-by-step explanation:

48/4 = 12 so 1 side = 12

the base of the triangle therefore must also be 12 so 38 - 12 = 26

26 + 36 = 62

(2 sides of triangle + 3 sides of square)

Answer:

x = 26 - 21 = 5

Answer:

x=5

Step-by-step explanation: Subtract 21 from both sides. x = 5.

Answer:

You can determine the type of triangle using the following facts related to the converse of the pythag theorem

if a^2+b^2<c^2, then it is an acute triangle

finally, if a^2+b^2=c^2, then it is a right triangle

A) $13.79 per ticket

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential increase function:  

A = P (1 + r) t  

Where:  

p = original price

r = increase rate (decimal form)  

t= years  

A = price after t years  

Replacing with the values given:  

A =7.50 (1+ [7/100]) ^9

A = $13.79 per ticket

Which is the most efficient way to solve this equation?

+4=17

Subtract 4

from both sides because that will result in an equivalent equation with

alone on one side.

Subtract 17

from both sides of the equation so all terms will be on the same side of the equal sign.

Nothing, because the equation is already solved.

Add 4

Answer:

35.06

Step-by-step explanation:

So you  have to multiply 27.50 by 0.075 to find the sales tax.

2.0625 ≈ 2.06

If the tip is off the original price, you multiply 27.50 by 0.2.

5.5

The whole meal is 27.50 + 5.50 + 2.06 = 35.06

Total cost of meal is $35.06.

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Given that,

The bill amount = $27.50

tax amount = 7.5%

tip amount = 20%

Now 7.5 % of bill amount

=  27.50x 7.5/100

=  27.50 x 0.075

=2.0625

≈ 2.06

Now 20% of bill amount is

= 27.50 x 20/100

= 27.50x0.2

= 5.5

Now,

The total cost

=  27.50 + 5.50 + 2.06

= 35.06

Hence $35.06 is the total cost.
