Explain how you know the right triangles are similar.

Answer:

The length of its side is 30 cm

Step-by-step explanation:

An equilateral triangle with the perimeter of 90cm.

In a Equilateral Triangle all sides are equal

i.e., all 3 sides are equal

Now,

90/3 = 30 cm

Thus, The length of its side is 30 cm

an equilateral triangle with the perimeter of 90cm, what is the length of its side?

30cm

Given,

Perimeter of the equilateral triangle = 90cm

We know that,

All three sides of an equilateral triangle are equal.

So,

90/3 = 30cm

The length of the side is 30cm.

Answer: 2g + 7 or 7 + 2g

Step-by-step explanation:

7 increased by twice g can be represented as 2g + 7 or 7 + 2g

Answer:

1 = 70

Step-by-step explanation:

The triangle is an isosceles.

Subtract the angle 40 from 180 (all angles in a triangle add up to 180

The bottom two angles are the same, so dividing the number given by 180 - 40 by 2

180 - 40 = 140

140 / 2 = 70

Hey there!

4y + 2x - y + 8

= 4y + 2x - 1y + 8

COMBINE the LIKE TERMS

= (4y - 1y + (2x) + (8)

= (4y - y) + (2x) + (8)

= (2x) + (4y - y) + 8

= 2x + 3y + 8

Therefore, your answer is: 2x + 3y + 8

Good luck on your assignment and enjoy your day!

Answer:

3y+2x+8

Step-by-step explanation:

All you really do is combine the like terms, which in this case is the 3y and the -y. think of the y more as -1y and that is why it's subtrcated.

Answer:

C

Step-by-step explanation:

6÷3=2

9÷3=3

combined that is 15/3

so the extra 1 goes back into the fraction

giving us 5 1/3

The most accurate determination for the number of 45.36 feet per second Tyrone traveled on his way to work.

Given that,

Using a stopwatch Tyrone determines it takes him 58.2 minutes to travel 30 miles to work the stopwatch measures to hundredths of a minute going by the accuracy of the stopwatch.

We have to determine,

Which is the most accurate determination for the number of feet per second Tyrone traveled on his way to work?

According to the question,

Tyrone determines it takes him 58.2 minutes to travel 30 miles to work,

the stopwatch measures to hundredths of a minute going by the accuracy of the stopwatch are determined by,

[tex]\rm Speed = \dfrac{Distance}{Time}[/tex]

Substitute the values in the equation,

[tex]\rm Speed = \dfrac{Distance}{Time}\\\\Speed = \dfrac{30}{58.2}\\\\Speed = \dfrac{50}{97} \ miles \ per \ minute[/tex]

If 1 mile = 5,280 feet, then his speed is,

[tex]\rm Speed = \dfrac{50}{97} \ miles \ per \ minute\\\\ Speed = \dfrac{50}{97} \times 5280 \\\\ Speed= \dfrac{26,400}{97}\ feet \ per \ minute\\[/tex]

And 1 minute = 60 seconds, then his speed is,

[tex]\rm Speed= \dfrac{26,400}{97}\ feet \ per \ minute\\\\ Speed= \dfrac{26,400}{97} \times \dfrac{1}{60} \\\\ Speed = \dfrac{4400}{97} \ feet \ per \ second \\\\ Speed = 45.36 \ feet \ per \ second[/tex]

Hence, The most accurate determination for the number of 45.36 feet per second Tyrone traveled on his way to work.

The actual lenght will be 6 fee

The actual width will be 4 feet

The scale factor that Jenna's father used to go from the drawing to the actual house is 1.5

The perimeter of the floor is 20 feet

The area of the first floor that Jenna's that father built is 24ft²

Given the conversion factor 2inches = 1feet

1) If Jenna's father is going to use the blueprint above to make a playhouse for her and the length of the entire first floor is 12 inches, the actual length in feet is expressed as:

12 inches = x

2inches = 1feet

_____________________________

2x = 12

x = 6 feet

Hence the actual lenght will be 6 feet

2) If the width of the entire first floor is 8 inches, the actual width is expressed as;

8 inches = x

2inches = 1feet

_____________________________

2x = 8

x = 4 feet

Hence the actual width will be 4 feet

3) Thee scale factor will be the ratio of the length to the width as shown:

Ratio = length/width

Ratio = 6/4

Ratio = 3/2

Hence the scale factor that Jenna's father used to go from the drawing to the actual house is 1.5

4) The perimeter of the floor = 2(L + W)

Perimeter = 2(6 + 4)

Perimeter = 2(10)

Perimeter of the floor is 20 feet

5) Area of the floor = length * width

Area of the floor = 6ft * 4ft

Area of the floow = 24ft²

Hence the area of the first floor that Jenna's that father built is 24ft²

The answer is C. -0.25; the rate at which Martin's distance from the finish line changes per minute

Answer:

Im pretty sure c Y=6

Step-by-step explanation:

9y+2=58

Subtract 2 from both sides.

9y=58−2

Subtract 2 from 58 to get 56.

9y=56

Divide both sides by 9.

y= 56/ 9  Which is Also 6.2

Complementary angles have a submission of 90 degrees thus :

[tex]angle \: \: A + angle \: \: B = 90°[/tex]

[tex](4x - 28)° + (4x - 8)° = 90°[/tex]

[tex]4x + 4x - 28 - 8 = 90[/tex]

Collect like terms

[tex]8x - 36 = 90[/tex]

Add both sides 36

[tex]8x - 36 + 36 = 90 + 36[/tex]

[tex]8x = 126[/tex]

Divide both sides by 8

[tex] \frac{8x}{8} = \frac{126}{8} \\ [/tex]

[tex]x = 15.75[/tex]

_____________________________________________

Now let's find the measure of A :

[tex]A = 4x - 28[/tex]

[tex]A = 4 \times (15.75) - 28[/tex]

[tex]A = 63 - 28[/tex]

Answer:

No

Step-by-step explanation:

Parenthesis means to multiply. So, to simplify the expression 3(x + 2), we need to distribute 3. In other words, we need to multiply 3 to x and to 2. Thus 3(x + 2) = 3x + 6.

Answer:

1) A

2) D

Step-by-step explanation:

1) You can see that both sides are equal and they have only one angle in common

2) This one is a bit more quirky. You have to complete the angles. First, you name the two that are in front of each other because of the vertice. In that way, you can see that they have one side in common (S), then the angle which we just explained (A), and finally another side (S)

Answer:

x² - 3

This expression is not linear

Step-by-step explanation:

Let x = unknown number

The sum of a number and negative 3

Sum = addition

We are adding the unknown number "x" and -3

So we have x + (-3) or just x - 3

The sum of that is multiplied by the unknown number

So we get ( x - 3 ) x

We can then simplify this expression to get  x² - 3x

Any expression with an exponent is not linear. Refer to the attached image for more validation. A linear expression would create a straight line. The expression x² - 3x creates a curved line
