Answer:

43°

Step-by-step explanation:

the inner corners of a triangle are alway 180°

so 180°-72°-65°=43°

Answer:

15 ans rln 1 and 17 ans rln3

Answer:

54

Step-by-step explanation:

It is the same as angle ABC

Answer: x = 21 degrees

Step-by-step explanation: Angle BCA is equal to angle x.

54 + 105 + x = 180

159 + x = 180 (add like terms)

x = 21 (subtract 159 from both sides)

Answer:

points (0,0), (1,4) are on the line

Step-by-step explanation:

We can take a x-value and substitute it in the equation to get a point on the graph (1 x 4 = 4). Any two points on the graph can be graphed together to create the line.

You can plot the two points to get the graph of y = 4x

Answer:

67.5 degrees

Step-by-step explanation:

The angles at the center of the figure = 360 degrees

Therefore, 3x + x + 90 degrees = 360 degrees

simplifying:

4x + 90 degrees = 360 degrees

4x = 360 - 90

4x = 270 degrees

x = 270÷ 4

x = 67.5 degrees

Step-by-step explanation:

Answer:

The slope is -48.5, and this shows that every hour he drives 48.5 km closer to his home.

Step-by-step explanation:

Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)

Answer:

A.

Step-by-step explanation:

You would subtract 2.45 by 10.00 and the answer would be 7.55 which leaves you with A.

Final Answer: [tex]3w[/tex]

Steps/Reasons/Explanation:

It is common addition and subtraction because they all have w after the number. This means they are the same variable. A plus minus (+-) would be a minus (-).

Question: Simplify the expression: [tex]-9w +- 6w + 10w + 8w[/tex].

Step 1: Simplify.

[tex]-9w - 6w + 10w + 8w[/tex]

Step 2: Simplify.

[tex]3w[/tex]

Answer:

The area of the large rectangle can be represented in two ways. Either the sum of each of the areas of the individual smaller rectangles, which is what the first equation represents, as its the base multiplied by the height (a) of each rectangle.

The second equation is a simplified version of the first one, and can be explained in three ways:

Each of the terms in the earlier equation had a common factor of a, which could be taken outside the parentheses.

or

Since the height is the same for each of the smaller rectangles, you can just multiply the height times the sum of the three smaller rectangle's widths

or

The width of the large rectangle is just the sum of each of the smaller widths, so the sum of those multiplied by a will give the area of the large rectangle.

Hope this helps!

Answer:

ITS 7 !!!!!!!!!!!!!!!!

Step-by-step explanation:

Answer:

its 3.5, not 7

Step-by-step explanation:

2 x 3.5= whatever its on, but its not on the 8. 4 x 3.5= whatever it is but its not on the 16, so THERE.

Answer:

18

Step-by-step explanation:

half of 36 is 18

so you would have an improper fraction and then turn it into 2

9514 1404 393

Answer:

Step-by-step explanation:

If a vertical line can be made to intersect the graph at more than one point, the relation is not a function.

Relations 1, 3, 4, 5 have points one above another, so are not functional relations.

Relations 2 and 6 pass the vertical line test, so are functional relations.

*seed attachment for diagram

Answer:

83°

Step-by-step explanation:

Given:

Philip = (8x + 12)°

Matt = (55 - 3x)°

George = (10x + 23)°

Required:

Measure of angle at George's position

SOLUTION:

Find the value of x

(8x + 12)° + (55 - 3x)° + (10x + 23)° = 180° (sum of the interior angles of a ∆)

8x + 12 + 55 - 3x + 10x + 23 = 180

Add like terms

15x + 90 = 180

15x = 180 - 90 (subtraction property of equality)

15x = 90

x = 90/15 (division property of equality)

x = 6

✔️George = (10x + 23)°

Plug in the value of x

George = 10(6) + 23 = 60 + 23

= 83°

Answer:

83

Step-by-step explanation:

I took the quiz.

Answer:

A

Step-by-step explanation:

The formula for the slope of the line is:

m = [tex]\frac{y_{1}-y_{2}}{x_{1}-x_{2}}[/tex]

Assuming that y1 is 17, y2 is -11, x1 is -9 and x2 is 5, we can plug it in the equation:

m={17-(-11)}/{-9-5}

m=28/-14

m=-2

Therefore, A

Answer: Correct me if I’m wrong but the answer should be 6,000 kg

Step-by-step explanation:

If you multiply 50 by 120 you get 6,000 or you can multiply 50 by 20 which equals to 1,000 and then do 1,000 multiplied by 6 and you get ur answer (this should be correct)

Answer:

y = 83.33 cm

Step-by-step explanation:

Relation between the rise in water level (h) and duration (t) to fill the water in the garden hose is proportional.

h ∝ t

h = kt

Here, k = Proportionality constant

If the rise in the water level of the hose = 13 cm

Time to fill the water up to 13 cm = 3 minutes

13 = 3k

k = [tex]\frac{13}{3}[/tex] cm per minute

Therefore, equation will be,

h = [tex]\frac{13}{3}t[/tex]

If a data point (19, y) lies on the graph,

y = [tex]\frac{13\times 19}{3}[/tex]

y = 82.33 cm

Therefore, y = 82.33 cm is the answer.

Answer:

i think its 1 1/5

Step-by-step explanation:

Answer:

z=4√5

Step-by-step explanation:

use the Pythagorean theorem to set up a system of equations. a^2 + b^2 = c^2

16+4= 20

20^2 = x^2 + z^2 400=x^2 + z^2 x^2=400-z^2

z^2 = 4^2 + y^2 z^2 = 16 + y^2

x^2 = 16^2 + y^2 x^2 = 256 + y^2 y^2=x^2-256

z^2=16+x^2-256

z^2=16+400-z^2-256

z^2=160-z^2

2z^2=160

z^2=80

z= √80 =4√5

Answer:

140 = 40 + 10x

Step-by-step explanation:

The watch is 140 in total. He can pay 40 dollars currently. 10x is the amount of payments there are. How much he can pay with each payment (10x) is unknown so that is why there is the variable.
