Answers

Answer:

B

Step-by-step explanation:

just use pyth then you'll get the answer

Answer:

B

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

let h be the hypotenuse, then

h² = 6² + 18² = 36 + 324 = 360 ( take the square root of both sides )

h = [tex]\sqrt{360}[/tex]

   = [tex]\sqrt{36(10)}[/tex]

   = [tex]\sqrt{36}[/tex] × [tex]\sqrt{10}[/tex]

   = 6[tex]\sqrt{10}[/tex] → B

Given the following system of equations: 2x + 3y = 12
2x - 2y = 2

What is the value of x + y? ​

Answers

Answer:

5

Step-by-step explanation:

2x + 3y = 12

2x - 2y = 2 // subtract second equation from first

5y = 10

y = 2

x = (2 + 2y) / 2 = y + 1 = 3

7. The price of a bike at Store A is 5/6 the price at store B. The price at store A is $150.60. Write and solve an equation to find out how much the bike is at store B. How much did you save by buying the bike at Store A.​

Answers

As a little tip that's helped me personally when I was taking algebra, making equations for word problems feels a lot easier when you "translate" equations you make into words to make sure that you're using the right equation.

Let's boil down what the question tells us. 5/6 of the price tag of a bike from Store B is the price of a bike from Store A, which is $150.60. Let's use the variable 'b' to represent the price of Store B's bike.

[tex]\frac{5}{6}[/tex] * b = 150.60

Try "translating" the equation above. "5/6 of the price of a Store B bike is equal to 150.60." That seems about right, doesn't it? Let's isolate 'b' so we can get an official answer.

Multiply both sides by 6 to get rid of the denominator:

[tex]\frac{5b}{6}[/tex] * 6 = 150.60 * 6

5b = 903.6

Divide both sides by 5 to get rid of b's coefficient:

[tex]\frac{5b}{5}[/tex] = [tex]\frac{903.6}{5}[/tex]

b = 180.72

The price of a bike from Store B is $180.72

If you need any help on anything I just did here, don't be afraid to ask. Good luck on your Algebra endeavors!

Graph the functions y=4^x+4-4 and y=4^x describe the translation in words between these two functions starting from y=4^x to y=^x+4-4.

Answers

Answer:

The two graphs are on the same place.

The translation from the first one to the second one implies a shift upwards of 4 units, and then a shift downwards of 4 units, resulting in the starting position.

A line, y = mx + b, passes through the point (1, 6) and is parallel to
y = 4x + 6. What is the value of b?

Answers

Answer:

Step-by-step explanation:

Let the line to be found be Line 2

Given:

Line 1 :

y = 4x + 6

Since y = mx + b

We can substitute and find that the slope of Line 1 is 4

Therefore slope of Line 2 = (4)

Line 2:

Point - (1,6)

Slope - 4

Therefore: 6 = (4)(1) + b

So equating it we get : b = 2

The area of a rectangle is 325 cm^2. What is the area of a rectangle in cm^2 with
sides 3 times as large?
i’m stuck, pls help

Answers

Answer:

2926 cm²

Step-by-step explanation:

The area of a rectangle is 325 cm^2. What is the area of a rectangle in cm^2 with sides 3 times as large?

Step 1

A rectangle has both Length and Width

Let us assume the Length = Width

The area of a rectangle is 325 cm²

Area = Length × Width

325 cm² = L²

L = √325 cm²

L = 18.027756377 cm

Approximately = 18.03 cm = Widtdh

Step 2

What is the area of a rectangle in cm² with sides 3 times as large?

From Step 1

L = 18.03cm

3 times as large = 18.03 cm × 3

= 54.09 cm

The Area for this rectangle

= A = L²

A =( 54.09 cm)²

A= 2925.7281 cm²

Approximately = 2926 cm²

Max and Maggie have to clean the house. It takes Max 9 hours to clean the house, while Maggie can complete the task in 4 hours. Their sister says that it will take 3 hours to complete if they work together. Explain each step in solving this equation, and determine if the sister is correct or not.

Answers

Answer:

3 hours

Step-by-step explanation:

Max cleans the house in 12 hours

Max in 1 hour cleans: 1/12 part of the house

Maggie cleans the house in 4 hours

Maggie in 1 hour cleans: 1/4 part of the house

In 1 hour they together do: 1/12 + 1/4 = 1+3/12 = 4/12 = 1/3 work

1 hour===1/3 work

X hours== 1 work

X/3 = 1

X = 3 hours.

Hence, they together complete the work in 3 hours.

And so, the sister is correct.
