Answers

Corresponding angles = angle 1 and angle 5

They are on the same side of the transversal cut (both to the left of the transversal) and they are both above the two black lines. It might help to make those two black lines to be parallel, though this is optional.

Other pairs of corresponding angles could be:

angle 2 and angle 6angle 3 and angle 7angle 4 and angle 8

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

Alternate interior angles = angle 3 and angle 5

They are between the black lines, so they are interior angles. They are on alternate sides of the blue transversal, making them alternate interior angles.

The other pair of alternate interior angles is angle 4 and angle 6.

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

Alternate exterior angles = angle 1 and angle 7

Similar to alternate interior angles, but now we're outside the black lines. The other pair of alternate exterior angles is angle 2 and angle 8

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

Same-side interior angles = angle 3 and angle 6

The other pair of same-side interior angles is angle 4 and angle 5. They are interior angles, and they are on the same side of the transversal.

Four sisters take turns using the computer an equal amount of time each night. They are allowed to use the computer from 4 p.m. to 10 p.m. Each sister can use the computer for at most minutes each night. In terms of the greatest number of hours and the minutes remaining, each sister can use the computer for at most hour(s) and minute(s) each night. Please hurry!!!!

Answers

Answer:

1.5 hours

Step-by-step explanation:

there are 6 hours in between the times of 4 and 10

so 4 sister split up 6 hours equally

to do this, we divide 6 and 4

6/4 = 1.5 hours

each sister can spend 1.5 hours on the computer

Answer:

1 hour and 30 minutes

Step-by-step explanation:

If four sisters get 1 hour each, 2 hours are left.

4 half hours make 2 hours.

Answers

Bonus each day: 1.5% x $87000 = $1305

factorise 6x²-14x-12​

Answers

Answer:

2(x - 3)(3x + 2)

Step-by-step explanation:

Given

6x² - 14x - 12 ← factor out 2 from each term

= 2(3x² - 7x - 6) ← factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × - 6 = - 18 and sum = - 7

The factors are - 9 and + 2

Use these factors to split the x- term

3x² - 9x + 2x - 6 ( factor the first/second and third/fourth terms )

= 3x(x - 3) + 2(x - 3) ← factor out (x - 3) from each term

= (x - 3)(3x + 2)

Thus

3x² - 7x - 6 = (x - 3)(3x + 2) and

6x² - 14x - 12 = 2(x - 3)(3x + 2) ← in factored form

Shawna is buying a rug for her room store a has the rug for $45 with a 10% discount store B has the same rug for $46 and is offering a $10 off coupon the sales tax is 6% on either purchase if sauna only has $40 to spend which store will see purchased a rug from and how much better Will she have left over

Answers

Answer:

Shawna buys her rug at STORE B and she has $1.84 left over after purchasing her rug.

Step-by-step explanation:

Store a

Store a sells their rug for $45

Store a offers a discount of 10%

Discount = 10% × $45 = $4.5

Amount payable after discount = $45 - $4.5

= $41.5

There is a sales tax of 6%

The total amount payable

Amount of sales tax + Discounted price of rug

Amount of sales tax = 6 % × $41.5

= $2.472

= Discounted amount + Sales tax

= $41.5 + $2.472

=$43.972

Store b

Store a sells their rug for $46

There is a sales tax of 6%

The total amount payable

Store b offers a 10 dollar coupon off for the rug

= $46 - 10

Amount payable after = $36

Amount of sales tax + price of rug(After coupon is deducted)

Amount of sales tax = 6 % × $36

= $2.16

Amount payable by Shawna in Store a = $36 + Sales tax

= $36 + $2.16

=$38.16

Since Shawna has , only $40 to spend, she buys her rug at STORE B

The amount she has left = $40 - $38.16

= $1.84

Answers

Answer:  ∠TRa = 30°, ∠aRA = 90°, ∠TRA = 120°

Step-by-step explanation:

I'm not sure if you need the angle of the left triangle only (= 30°)

or if you need the the triangle plus the rectangle (= 120°)

Left Triangle (∠TRa)

The hypotenuse is twice the base so it is a 30° - 60° - 90° triangle

where the base corresponds to the 30° angle.

Rectangle (∠aRA)

A rectangle has four right angles --> four 90° angles.

Angle Sum Theorem

∠TRA = ∠TRa + ∠aRA

          = 30° + 90°

          = 120°

Find the value of m. A. 32 B. 63 C. 50 D. 74

Answers

Answer:

A

Step-by-step explanation:

Tangents drawn to a circle from an external point are congruent, thus

the triangle formed by the 2 tangents is isosceles with base angles of 74°

m = 180° - (74 + 74)° = 180° - 148° = 32° ( sum of angles in Δ )

The value of the measured angle of m is 32°.

What is a Tangent of Circle?

A tangent of a circle is defined as a single point where a single straight line touches or intersects the circle. A line that never touches the inside of the circle is called a tangent.

The line connecting the outer point will cut the angle between the tangents in bisect and the center are equal to each other.

According to the given figure as

A circle with center O,

Since there are two tangents to the circle drawn from an external point.

therefore the lengths of tangents drawn from an external point to a circle are equal.

So, the triangle formed by the 2 tangents is isosceles with base angles of 74°

We know that sum of angles in the triangle is 180 degrees

So ∠ m = 180° - (74 + 74)°

⇒ ∠ m = 180° - 148°

∠ m = 32°

Hence, the value of the measured angle of m is 32°.

Answer:

3.92*10^3mm

Step-by-step explanation:

In the diagram it gives you 7900mm. There is a figure which was given underneath written 900mm. use 7900 to subtract 900 you will get 7000. Then you can use the Pythagoras theorem to solve it, with a= height, b=5800mm and c=7000mm where, a^2+b^2=c^2.

Answer:

3919 mm

Step-by-step explanation:

Length of hypotenuse = 7900 - 900 = 7000 mm

Base = 5800 mm

Let the height of the triangle be h mm

Therefore, by Pythagoras theorem:

[tex] h = \sqrt{7000^2 - 5800^2} [/tex]

[tex] h = \sqrt{49000000- 33,640,000} [/tex]

[tex] h = \sqrt{15,360,000} [/tex]

[tex] h = 3,919.18359\: mm[/tex]

Answer:

θ = 36.9°

Step-by-step explanation:

Trigonometric ratios in a right triangle will be,

Sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex] = [tex]\frac{\text{AC}}{\text{AB}}[/tex]

Cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex] = [tex]\frac{\text{BC}}{\text{AB}}[/tex]

Tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex] = [tex]\frac{\text{AC}}{\text{BC}}[/tex]

In the picture attached,

Given sides are,

AB = 5 and BC = 4

Therefore, to find the given angle θ only Cosine will be applicable.

Cos θ = [tex]\frac{\text{BC}}{\text{AB}}[/tex]

         = [tex]\frac{4}{5}[/tex]

θ = [tex]Cos^{-1}(0.8)[/tex]

If the numbers 4, 5 and 6 are each used exactly once to replace the letters in the expression A ( B − C ), what is the least possible result?

Answers

Answer:

The least possible result is -10.

Step-by-step explanation:

Given the numbers 4, 5 and 6 are to be chosen one of the letters A, B or C.

First of all,

Let A = 4, B = 5 and C = 6

[tex]A(B-C) = 4 \times (5-6) = 4 \times -1 = -4[/tex]

Let A = 4, B = 6 and C = 5

[tex]A(B-C) = 4 \times (6-5) = 4 \times 1 = 4[/tex]

Let A = 5, B =4 and C = 6

[tex]A(B-C) = 5 \times (4-6) = 5 \times -2 = -10[/tex]

Let A = 5, B = 6 and C = 4

[tex]A(B-C) = 4 \times (6-4) = 4 \times 2 = 8[/tex]

Let A = 6, B = 4 and C = 5

[tex]A(B-C) = 6 \times (4-5) = 6 \times -1 = -6[/tex]

Let A = 6, B = 5 and C = 4

[tex]A(B-C) = 6 \times (6-5) = 6 \times 1 = 6[/tex]

Summarizing the above values in the form of a table:

[tex]\begin{center}\begin{tabular}{ c c c c}A & B & C & A(B-C)\\ 4 & 5 & 6 & -4\\ 4 & 6 & 5 & 4\\ 5 & 4 & 6 & -10\\ 5 & 6 & 4 & 10\\ 6 & 4 & 5 & -6\\ 6 & 5 & 4 & 6\end{tabular}\end{center}[/tex]

How many ways can you distribute 4 different balls among 4 different boxes?

Answers

15 is the answer. We know we can split the balls into four groups: 4-0-0-0, 3-1-0-0, 2-2-0-0, 2-1-1-0, 1-1-1-1.

Case 1: 4-0-0-0 has only 1 way we can assign the balls to different boxes.

Case 2: 3-1-0-0 has (I think) 4 ways we can assign the balls to different boxes. The one ball can go anywhere, and the three other balls must go in a different box

Case 3: 2-2-0-0 has 4C2 = 6 ways to choose two balls to go in one box, then the other two balls must go in separate boxes. But since order doesn't matter, (there is no first box or second box), we divide by 2.

Case 4: 2-1-1-0 has (again) 4C2 = 6 ways to choose two balls to go in one box, then the other balls go in seperate boxes.

Case 5: 1-1-1-1 has only 1 way.

1 + 4 + 6/2 + 6 + 1 = 15.
