Answer 2

Answer:

x = 30

Step-by-step explanation:

First add up all the known angles (270), since this is a five sided polygon, the measure of the interior angles is 540. Subtract 540 by 270 to know what 9x equals (270 = 9x)

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface.

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

As, per the definition of Surface and Volume.

This triangle is a multiple of one of the triples listed here. What is the hypotenuse?

Answers

Answer:

50 units

Step-by-step explanation:

you use Pythagorean-theorem which means A^2+B^2 =C^2

It does not matter the order of A and B because it is adding. But C is the hypotenuse.

If we plug in the # this is what it looks like...

14^2 +48^2=C^2

48^2+14^2=C^2

14*14= 196

48*48=2,304

then you add

196+2,304=C^2

2,500= C^2

and you can use a calculator for this part you do 2,500

with the 2,500 you use the sign as in the picture and it gives you...

which means 50*50 = 2,500

50 units is the answer

Answers

Answer:

R=110 degrees

B=110 degrees

Step-by-step explanation:

R and B are the same angle, we minused the mesure of G and since angle O is same as the other angle we multiplied 60 by two and then added 20 which gave us 140

360-140=R+B

220=R=B

110=R

110=B

Answer:

m<R = 120 degrees, m<B = 100 degrees

Step-by-step explanation:

1. i found the blue line and the angle of any line is 180 degrees

2. since angle O is 60 you have to subtract it from 180 -60 = 120 = m<R.

3. this one is more complicated you have to subtract angle O and angle G which is 20 degrees so you add 20 + 60 = 80 and then you take the sum and subtract it from 180: 180 - 80 = 100

Harper only has $15 to spend at the grocery store. She buys Doritos that cost $2 per bag and one sandwich for $8. Which solution set would represent the options for the number of bags of Doritos she can buy.

Answers

Answer:

2x + 8 ≤ 15

Step-by-step explanation:

Hi,

2x represents the cost for each bag of doritios. The 8 is the cost of the sandwitch. And 15 is how much money she can spend :)

Answer:

2d + 8 ≤ 15

Step-by-step explanation:

Let the amount of Doritos bags be represented by d.

2d + 8 ≤ 15

With this, we can solve.

2(3) + 8 ≤ 15

6 + 8 ≤ 15

14 ≤ 15

The equation is true, and we cannot go any further.

The answer is ≤ 3.

Alan used the expression StartFraction 5 over 9 EndFraction (F minus 32), where F is a temperature in degrees Fahrenheit, to convert a temperature from Fahrenheit to Celsius. He evaluated the expression as shown below and found that 45 degrees Fahrenheit was equivalent to –7 degrees Celsius.

StartFraction 5 over 9 EndFraction (F minus 32) = StartFraction 5 over 9 (45 minus 32) = 25 minus 32 = negative 7

What error did Alan make?
He substituted 45 for F instead of –7 and should have found the answer to be Negative 21 and two-thirds degrees Celsius.
He did not combine within the parentheses first before multiplying and should have found the answer to be 7 and StartFraction 2 over 9 EndFraction degrees Celsius.
He multiplied 45 by the fraction incorrectly and should have found the answer to be 49 degrees Celsius.
He divided 5F by 9 before subtracting 32 and should have found the answer to be 21 and StartFraction 4 over 9 EndFraction degrees Celsius.

Find the distance between each pair of points

5: (0, 8.8)

6: (0, 6)

7: (10, 0)

Step-by-step explanation:

6-2=4

5.5-(-3.3)=8.8

-7/12-(-1/2)

31/4-(-9/4)=10

The distances between the points are:

4) 45) 8.86) 67) 10How to find the distances between the points?

The distance between two points (a, b) and (c, d) is given by:

[tex]distance = \sqrt{(a - c)^2 + (b - d)^2}[/tex]

4) Here the points are (-5, 2) and (-5, 6) so the distance is:

[tex]distance =\sqrt{(-5 - (-5))^2 + (6 - 2)^2} = 4[/tex]

5) Here the points are (4.5, -3.3) and (4.5, 5.5), so the distance is:

[tex]distance = \sqrt{(4.5 - 4.5)^2 + (-3.3 - 5.5)^2 } = 8.8[/tex]

6) Here the points are (5 + 1/2, -7 - 1/2) and (5 + 1/2, -1 - 1/2), so the distance is:

[tex]distance = \sqrt{(5.5 - 5.5)^2 + (-7.5 - (-1.5)^2)} = 6[/tex]

7) Here the points are (-2.25, -8) and (7.75, -8), so the distance is:

[tex]distance = \sqrt{(-2.25 - 7.75)^2 + (-8 + 8)^2} = 10[/tex]
