Answer:

A ∆ with an exterior angle :116° & two interior angles 7x+6 & 4x

The value of angle 7x+6

we know that ,

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non adjacent interior angles of the triangle.

so,

[tex]7x + 6 + 4x= 116 \\ 11x + 6 = 116 \\ 11x = 116 - 6 \\ 11x = 110 \\ x = 110 \div 11 \\ x = 10[/tex]

so ,the measure of green angle would be

[tex]7x + 6 \\ placing \: the \: value \: of \: x \: as \: 10 \\ 7 \times 10 + 6 \\ = 70 + 6 \\ = 76[/tex]

To verify our answer ,the sum of the resultant value of green angle and 4x should be 116°(the exterior opposite angle)

so,

[tex]7x + 6 + 4x = 116 \\ 7 \times 10 + 6 + 4 \times 10 = 116 \\ 70 + 6 + 40 = 116 \\ 76 + 40= 116 \\ 116 = 116 \\ \\ hence,\: verified[/tex]

Solution:

Note that:

Simplify the equation to find x.

Substitute the value of x into the measure of the green angle.

The measure of the green angle is 76°.

The given expression is irreducible or prime in nature.

Given expression is

[tex]3x^2+x+7[/tex]

The discriminant tells us whether there are two solutions, one solution, or no solutions.

Since Discriminant of this quadratic function is,

[tex](1)^2-4*3*7=-83[/tex] , negative

So factors without imaginary terms are not possible.

Thus given expression is irreducible or prime in nature.

Zalia paid all total for her day at the science museum is $41.43 including all taxes and tips and other expenses.

It is given that

Admission to the museum = $12.50 per person

Number of persons= 2

Sandwich charge = $5.95

Apple charge = $1.25

Drink charge = $1.69

Tax rate = 7.25%

Tip = 15%

The percentage is value per hundred

Total amount without tax and tip(a)= 12.50*2+5.95+1.25+1.69 = $33.89

Tax(b) = 7.25% of $33.89 = 7.25*33.89/1000= $2.457025

Tip(c) = 15% of $33.89 = 15*33.89/100 = $5.0835

Net amount = a+b+c = $41.43

Therefore, Zalia paid all total for her day at the science museum is $41.43

The original price would be $38 before the sale and without the coupon.

Given that Mai offers a $5 off the regular price of one book bag coupon. The store first uses the discount, then deducts 30% off the lowered price.

The percentage is defined as a ratio expressed as a fraction of 100.

Let the original price would be x before the sale and without the coupon.

As per the given condition,

Since Mai pays $23.10 for the bookbag

⇒ (x -5) - 30% (x -5) = 23.10

⇒ (x -5) - 0.30(x -5) = 23.10

Apply the distributive property of multiplication,

⇒ x - 5 - 0.30x + 1.5 = 23.10

Rearrange the likewise terms and apply the arithmetic operation,

⇒ x - 0.30x = 23.10 + 5 - 1.5

⇒ 0.70x = 26.60

⇒ x = 29.60/0.70

⇒ x = 38

Therefore, the original price would be $38 before the sale and without the coupon.

Hello! In order to solve the first problem, you need to know the properties of a rhombus.

Some basic rules that apply to the problem you should know are:

To be congruent, line segments must be equal in length. The same rule applies to angles, they must be of equal measure.

This being said,

1. HT is congruent to MA

2. ST is congruent to MS

3. AMH is congruent to ATH

4. If angle MHT is 80 degrees, than angle MAT is 80 degrees as they are vertical (opposite) angles. This means they are always congruent.

5. If line MH = 9, then due to congruency AT must equal 9.

A square is 360 degrees. Every line is equal, every angle is equal.

There are four right angles in a square. A right angle equals 90 degrees.

Since every line has the same length, they are all congruent.

1. True

There are no angles less or more than 90 degrees in a perfect square.

2. False

KD and IN are not perpendicular since they do not intercept. They are parallel.

3. False

Every angle in a perfect square is 90 degrees.

4. True

You can draw out lines to get a better perception of KN and ID. They are congruent due to properties of a square.

5. True

Answer:

C.

Step-by-step explanation:

Multiply both sides by 15, which gives you r≥-75

Since the graph has to go in the direction of numbers greater than -75, that would be -74, -73, -72, etc. So, it is C.

Answer:

13. 204.49 cm²
14. 15 cm²
15. 36 cm²

Step-by-step explanation:

Area of a square is:
A = a² where a is the side length

A = 14.3² cm

A = 204.49 cm²

Area of a triangle is:
[tex]A = \frac{hb}{2}[/tex] or [tex]A = \frac{1}{2}hb[/tex]  where h is the vertical height and b is the base length

A = (5×6)÷2

A = 30÷2

A = 15

Area of a rectangle is:
A = L×W where l is the length and w is the width

A = 8×4.5

A = 36

Let's find slope:-

Slope:-

[tex]\\ \rm\Rrightarrow m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \rm\Rrightarrow m=\dfrac{3-5}{4+9}[/tex]

[tex]\\ \rm\Rrightarrow m=\dfrac{-2}{13}[/tex]

The lower bound of this interval is 51.08, and the upper bound is 58.92.

Given:

Mean = 44

Standard deviation = 9

n = 36

The formula for the confidence interval of the sample mean:

Confidence Interval = [tex]X \pm z * (\sigma / \sqrt n)[/tex]

For a 95% confidence level, the z-score is approximately 1.96.

Plugging in the values into the formula, we have:

Confidence Interval = 44 ± 1.96 * (9/ √36)

                                 = 44 ± 1.96 * (9/ 6)

                                 = 44 ± 1.96 * 1.5

                                 = 44 ± 2.94

Therefore, the symmetrical interval that includes 95% of the sample means is (46.94, 41.06).

Answer:

Step-by-step explanation:

Let number of chocolate cakes = c

Number of lemon cakes = l

Total cakes = 27

c + l = 27 ---------------(I)

Total slices = 170

7c + 6l = 170  ---------------(II)

Multiply equation (i) by (-7) and then add. So, c will be eliminated and we can find the value of  l

(I) * (-7)        -7c - 7l = -189

(II)                7c + 6l = 170     {Now add}

                         - l    = -19

l = 19

Plugin l = 19 in equation (I)

c + 19 = 27

c = 27 - 19

c = 8

Number of chocolate cakes = 8

Number of lemon cakes = 19

Using subtraction of normal variables, it is found that Riley is not correct, as the mean is of 8 - 8 = 0.

The mean is the subtraction of the means, while the standard deviation is the square root of the sum of the variances.

Researching this problem on the internet, it is found that, for both samples, the mean is of 8, hence:

8 - 8 = 0.
