Answer:

Step-by-step explanation:

x + 60° = 180° ( interior angles )

[tex]x + {60}^{o} = {180}^{o} \\ x = {180}^{o} - {60}^{o} \\ x = {120}^{o} \\ [/tex]

x = z ( opposite angles )

z = 120°

y + 25° + 120° = 180°

(The sum of all interior angles of any triangle is equal to 180°)

[tex]y + {25}^{o} + {120}^{o} = {180}^{o} \\ y + {145}^{o} = {180}^{o} \\ y = {180}^{o} - {145}^{o} \\ y = {35}^{o} \\ [/tex]

The value of y in the given figure is (b) 35°

Since m||n, hence:

a + 60 = 180 (sum of consecutive interior angles formed by two parallel lines are supplementary)

a + 60 = 180

a = 120°

a = b (vertical opposite angles are congruent to each other)

120 = b

b = 120°

y + 25 + b = 180 (sum of angles in a triangle)

y + 25 + 120 = 180

y + 145 = 180

y = 35°

Hence the value of y is (b) 35°

y  =  −  x

The equation is given by

y  =  m  x  +  n  since  m  =  −  1  we get  y  =  −  x  +  n

the line passes Point  P  (  0  ;  0  )  so we get  n  =  0

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

given:

0.4x = 2.8

Now, solving for x

Dividing both side by 0.4 we get

0.4x/ 0.4 = 2.8 / 0.4

x = 28/4

x= 7

Hence, the value of x is 7.

Fatima's claim is not supported by the table because, the distribution is skewed right, with a median of 0.4 field goal advantage.

From the table, the median position is calculated as:

[tex]\mathbf{Median = \frac{1}{5} th}[/tex]

[tex]\mathbf{Median = 0.2\ nd }[/tex]

The 0.2nd data falls in the 0.4 field goal category.

So, the median element is:

[tex]\mathbf{Median = 0.4}[/tex]

However, the distribution of the table are concentrated on the left.

This means that, the distribution is not uniform, instead it is skewed right.

A uniform distribution has a skewness of 0.

Hence, Fatima's claim is not supported by the table

Answer:

20°

Step-by-step explanation:

If it's an isosceles triangle, the two remaining angles should be equal. (Angles opposite to equal sides are equal)

∴ one remaining angle = (180° - 140°)/2

                                      = 40° / 2

f(7) = 11

Step-by-step explanation:

Given the linear function, f(x) = 2x - 3:  

In order to find the value of f(7), simply substitute the value of the input, x = 7 into the function:

f(x) = 2x - 3

f(7) = 2(7) - 3

f(7) = 14 - 3

f(7) = 11

Therefore, the value of f(x) when x = 7 is:

Answers:

one small box = 30 pounds

one large box = 40 pounds

==========================================================

Work Shown:

S+L = 70 since the two boxes combine to 70 pounds.

70S = weight of 70 small boxes

50L = weight of 50 large boxes

70S+50L = weight of 70 small and 50 large

70S+50L = 4100

The system of equations is

[tex]\begin{cases}S+L = 70\\70S+50L = 4100\end{cases}[/tex]

There are a few ways to solve this system. I'll use substitution.

I'm going to isolate L in the first equation like so

S+L = 70

L = 70-S

Which I'll then plug into the other equation to solve for S

70S+50L = 4100

70S+50(70-S) = 4100

70S+3500-50S = 4100

20S+3500 = 4100

20S = 4100-3500

20S = 600

S = 600/20

S = 30

Each small box is 30 pounds.

Use this value of S to find L

L = 70-S

L = 70-30

L = 40

Each large box is 40 pounds.

Like we expect, each large box weighs more compared to any given small box.

------------------

Check:

Both equations are true for the ordered pair (S,L) = (30,40). Therefore, the answers have been confirmed.

sell 48 tickets at the door.

Step-by-step explanation:

1. Distribution; 5x+160≥400

2. Subtract 160 from both sides; 5x+160-160≥400-160

3. you are left with; 5x≥240

4. divide 5 from both sides; 5x/5≥240/5

5. you are left with; x ≥ 48

Meaning; they need to sell 48 or more tickets at the door to reach their goal of $400.
