Diego started with this shape Diego moves the shape down, turns it 90 degrees clockwise then moves the shape to the right

Answers

Transformation involves changing the position and/or dimension of a shape, a line or a point.

I've added as an attachment, the result of the transformation.

From the question, the following transformations were performed by Diego.

Move downward ----- > Turn 90 degrees clockwise ----- > Move to the right

Move downward

When a shape is moved downward, the new position of the shape will be directly under its previous location

Turn 90 degrees clockwise

This means that the shape will be rotated, 90 degrees to the right. However, the position of the shape will remain unchanged.

Move rightward

When a shape is moved rightward, the new position of the shape will be directly to the right of its previous location

A triangle has three angles. The first angle measures 20 less than a number. The second triangle is three
times the number. The third is the number. What are the measurements of each of the three angles in this
triangle?

Answers

Answer:

first angle is 20, 2nd is 120, 3rd is 40.

Step-by-step explanation:

with these words, "20 less than a number, Three

times the number, is the number." We can set up the equation x-20+3x+x = 180. combine like terms and we get 5x-20=180. add 20 to both sides to get 5x=200 then divide 200 by 5x to get x = 40. We can then plug 40 into each of the expressions, x-20, 3x, x, to get our angles.

a. Write an expression with parentheses to describe how much the homeowner ownes for labor.

b. Evaluate your expression to calculate the cost of the labor.​

Answers

a) 20(x)=y

b) $120

Let x= number of hours

Let y= Cost of labor

20 will remain constant, what matters is how many hours are being worked. If it's $20 per hour then it's safe to assume 1 hour is 20 dollars worth of labor. Due to it being per hour you have to multiply the rate by however many hours worked to get your final cost.

find the distance between the two points in simplest radical form

Answers

2 over 17 is the answer to this problem

The distance between the two points (7, - 1) and (9, - 9) is,

d = √68

We have to given that,

To find the distance between the two points (7, - 1) and (9, - 9)

Since, The distance between two points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

Hence, We get;

The distance between the two points (7, - 1) and (9, - 9) are,

d = √ (9 - 7)² + (- 9 + 1)²

d = √4 + 64

d = √68

Therefore, the distance between the two points (7, - 1) and (9, - 9) is,

d = √68

The problem is
3x+4y=50
-2x=y

Answers

Answer:

x = -10

y = 20

Step-by-step explanation:

y = -2x

so

substituting the value in equation ii

3x + 4y = 50

or, 3x + 4(-2x) = 50

or, 3x + (-8x) = 50

or, 3x-8x = 50

or, -5x = 50

so, x = -10

so

y = -2x

or, y = -2*(-10)

so, y = 20

Mario is 68.5 inches tall. Tyler is 63.25 inches tall. How much taller is Mario than Tyler

Answers

Answer:

5.25inches

Step-by-step explanation:

difference in height = 68.5-63.25 =5.25

Height of Mario Hm = 68.5 inches

Height of Tyler Ht = 63.25 inches

Evidently, Hm > Ht

Now difference = Hm - Ht = 68.5 - 63.25

= 5.25 inches

Answer: Mario is 5.25 inches taller than Tyler.

Evaluate with help of distributive property :

Answers

Answer:

1 : 57,800.

2: 268,335

Step-by-step explanation:

hope it helps you

The expressions are evaluated using distributive property below -

We have -

i. 425 x 136

ii. 4005 x 67

We have to evaluate them with help of distributive property.

State the  property of distributivity of multiplication over addition.

Distributive property of multiplication over addition :  

a × (b + c) = a × b + a × c

According to question, we have -

i. 425 x 136

ii. 4005 x 67

Now -

425 x 136 = 425 x (6 + 30 + 100) = 425 x 6 + 425 x 30 x 425 x 100

and

4005 x 67 = 4005 x (60 + 7) = 4005 x 60 + 4005 x 7

Hence, the evaluation using distributive property is done.
