Answer:

a.) 130°

b.) 70°

Step-by-step explanation:

For a given triangle

The sum of all angles on a straight line is equal to 180°

Now,

50° + a = 180°

Subtract 50° from each side we get,

50° - 50° + a = 180° - 50°

a = 130°

Thus, The size of the angle marked a is 130°

The sum of all angles in a triangle is equal to 180°

Now,

b + 50° + 60° = 180°

b + 110° = 180°

Subtract 110° from both side we get,

b + 110° - 110° = 180° - 110°

b = 70°

Thus, The size of the angle marked b is 70°

If 2.383 is rounded to the nearest hundred the answer is 2.38

[tex]\huge\bold\blue{2.38}[/tex]

Explanation:

2 - ones

. - decimal point

3 - tenths

8 - hundredths

2 - thousandths

8 is the digit in the hundredths place

look at the number on its right (which is 2)

if: < 5, just copy the number until the nearest hundredths.

if: > or = 5, add 1 to the hundredths then copy the number until the nearest hundredths

Answer:

x = - 14

Step-by-step explanation:

Given equation

Putting the value of y

Hope it's helpful!

ᔕEᒪEᑎᗩ328

The value of x for the given equation -3x = y + 51 such that the value of y is -9 will be -14.

An equation is said to be linear if the maximum power of the variable is consistently unity.

More than one variable may be present inside a linear equation.

A formula known as an equation uses the same sign to denote the equality of two expressions.

As per the given equation,

-3x = y + 51

At y = -9

-3x = -9 + 51

-3x = 42

x = -14

Hence "The value of x for the given equation -3x = y + 51 such that the value of y is -9 will be -14".

Answer:

a = 57.5

b = 57.5

Step-by-step explanation:

XY=XZ so c=d

[tex]c = d = \frac{180 - 65}{2} = 57.5[/tex]

Now draw the XH

So angle YXH = 180 — 90 — 57.5 = 32.5

a+YXH=90

a+32.5=90

so a = 57.5

We know that a + 65 + b = 180

So 57.5 + 65 + b = 180

b = 180 — 122.5

b = 57.5

From the above diagram we can conclude that ~

Angle c = Angle a (Alternate interior Angle pair)

Angle d = Angle b (Alternate interior Angle pair)

and,

because their opposite sides are equal.

now, according to linear pair property ~

replacing Angle a with Angle c and Angle d with Angle b, because they are equal to one another ~

(because Angle c = Angle d)

So,

Answer:

1/12

Step-by-step explanation:

find the least common multiple of the denominators.

which is 12

so 1/4=3/12

2/3=8/12

1/2=6/12

so 3/12- 8/12 - 6/12 = -11/12

so there is 1/12th pieces left after they all ate their portions of the pie

Answer: The answer is 40.

Answer:

B:8x-9y=23

Step-by-step explanation:

First find the slope:

m= y2-y1/x2-x1

y2 is 3

y1 is -1

x2 is 1/2

x1 is -4

3-(-1) is 4

1/2-(-4) is 9/2

Now the equation looks likes this:

4 / 9/2

Which can be rewritten as

4*2/9

Thus the slope is 8/9

So the equation is

y=8/9x+b

Now you can substitute to find the y-intercept:

(you can do either (-4,1) or (1/2,3)

I am going to do (1/2,3) since it is easier

3=8/9(1/2)+b

Simplify:

3=4/9+b

Subtract 4/9 on both sides:

b=23/9

Thus the equation is

y=8/9x+23/9

Multiply 9 on both sides:

9y=8x+23

Subtract 8x on both sides:

8x-9y=23

Hope this helps!

Answer:

A. C = (d-ab)/a

Step-by-step explanation:

a(c + b) = d

a(c + b)/a = d/a

c + b = (d/a)

c = (d/a) - b

a(c + b) = d

ac + ab = d

ac = d - ab

ac/a = d/a - ab/a

c = (d/a) - b

Answer:

Taxi Cost = $47.78

Step-by-step explanation:

Taxi Cost = Cost of the ride + (Cost of the ride × sale tax %)        5% = .05 as a

                                                                                                          decimal

Taxi Cost = $45.50 + (45.50 × .05)

 Taxi Cost = $45.50 + $2.275)

  Taxi Cost = $47.775

   Taxi Cost = $47.78

is

y = 17x

Step-by-step explanation:

After 1 hour , 17   bicycles are produced

After 2 hours, 34 bicycles are produced

Ratio of bikes produced per hour after one hour is

= no. of bikes produced after 1 hr / no of hours

= 17 / 1 = 17

Ratio of bikes produced per hour after two hours is

= no. of bikes produced after 2 hrs / no of hours

= 34 / 2 = 17

a. equal

b. is

equation of y is

no of bikes produced = (rate/ hour) * no of hours

y = 17 * x
