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

Answer:

True!!

4(9a+6) using the distributive property is  36a+24

Step-by-step explanation:

Answer:

True.

Step-by-step explanation:

We have a 4, next to an (.

We multiply the four.

[tex]4[/tex]×[tex]9a[/tex]

4×[tex]6[/tex]

= 36a+6

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

Answer:

<PRS = 45

Step-by-step explanation:

In a square, all 4 angles are complementary so:

<PRS + <PRQ = 90

<PRS + 45 = 90

<PRS = 45

Answer:

Answer:

2 1/4

Step-by-step explanation:

[tex]4\frac{1}{4} - 1\frac{3}{4}[/tex]

[tex]3\frac{1 - 3}{4}[/tex]

[tex]2\frac{4-3}{4}[/tex] = 21/4

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

x + y = 5

Answer:

c

Step-by-step explanation:

its c , absolutely.............

Answer:

C * 180 = 4x + 107

Step-by-step explanation:If you add all sides by each other all you would do next is add the 4x to get your 180

Answer:

1/2

Step-by-step explanation:

To find slope just compare two points on the graph and then put them into fraction form like so y/x

Answer:

6

Step-by-step explanation:

replace a by 3

when a=3

2(3)=6

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!

In your diagram, E appears to be the MAXIMUM value of the data (70).

Answer:

The red is 1/3 and yellow is 1/4

Step-by-step explanation:

there are 3 colors and 1 of them is red so 1/3 same goes to the yellow 4 colors and  is 1 yellow so 1/4

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.

Answer:

? = 20

Step-by-step explanation:

Since the figures are similar then the ratio of corresponding sides are equal, that is

[tex]\frac{12}{15}[/tex] = [tex]\frac{?}{25}[/tex] ( cross- multiply )

15 ? = 300 ( divide both sides by 15 )

? = 20

Answer:

The answer is red, green, blue.

Step-by-step explanation:

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

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.

Hope it helps.
