Answer:

90

Step-by-step explanation:

5*-9=-45

-45*-2=90

Answer:

90

Step-by-step explanation:

Let's solve this step by step:

(5) · (-9) · (-2)

First, there are two negatives in this equation. They will cancel each other out, to simply make 9 · 2:

5 · 9 · 2 =

Now, we do the multiplication:

5 · 9 · 2 = 45 · 2 = 90

90 is the answer!

Answer:

Isosceles Triangle Theorem

Step-by-step explanation:

An isosceles triangle is a tringle that has a pair of congruent sides and a pair of congruent angles. If the triangle has two congruent angles its isosceles. So therefore, you would use the Isosceles Triangle Theorem.

The Isosceles triangle theorem is used to determine if the base angles of a triangle are congruent.

"The angles that have the base as one of the side of triangle. "

"It is a triangle that has any two sides equal in length and angles opposite to equal sides are equal in measure."

For given question,

We need to find the theorem that is used to determine if the base angles of a triangle are congruent.

We know that the Isosceles triangle theorem states that 'If two sides of a triangle are congruent, then angles opposite those sides are congruent.'

In isosceles triangle any two sides of the triangle are equal in length.

If we draw the angle bisector for an angle between two equal sides, then we get two triangles.

Then by SAS congruence postulates we can prove that both the triangles  are congruent and so the base angles of a triangle are congruent.

Therefore, an Isosceles triangle theorem is used to determine if the base angles of a triangle are congruent.

Here, we want to state the width of the deck in the drawing given the scale for the actual scale to the scale drawing.

The given ratio is 7 ft to 1 in

Now we will have 17.5 to x in

x * 7 = 17.5 * 1

7x = 17.5

x = 17.5/7

x = 2.5 inches

    Statements                              Reasons

1. GH║KL                                  1. Given

2. J is the midpoint of HK       2. Given

3. JH ≅ JK                                3. Definition of the midpoint of a segment

5. ∠GJH ≅ ∠KJL                      5. Vertically opposite angles

6. ΔGHJ ≅ ΔLKJ                      6. By ASA theorem of congruence

We have to prove the statement, ∠GHJ = ∠LKJ

Given; GH || KL, J is the midpoint of HK.

To prove; ∠GHJ = ∠LKJ

Given; J is the midpoint of HK,

By definition midpoint of a segment,

The midpoint is the middle part of the line segment J, it is equidistant from both endpoints it is the centroid of the segment of the endpoints.

JH ≅ HK

Then, by the property of alternate interior angles,

∠JKL≅ ∠JKH

Therefore, by the property of vertically opposite angles,

When two lines intersect they form four angles. Vertical angles are the angles that are opposite to each other. Any two intersecting lines form two pairs of vertical angles that are opposite to each other.

∠GJH ≅ KJL

By ASA congruence theorem,

When two triangles are congruent to each other - If two angles and the involved side of one triangle is equivalent to the two angles and the included side of the other triangle.

ΔGHJ ≅ ΔLKJ

Hence Proved.

Answer:

y = 2x - 3

Step-by-step explanation:

Since the line needs to be parallel, you can take the slope of the other equation and input it into y = mx + b:

y = 2x + b

Next, to have it intercept at the given coordinates, input the coordinates into the equation and solve for b:

-1 = 2 ( 1 ) + b

-1 = 2 + b

-1 - 2 = b

-3 = b

Now input the "b" value into the equation and you have the answer:

y = 2x - 3

Answer:

125,000

Step-by-step explanation:

Given that :

Sequence of three numbers chosen from 0 to 49 inclusive

Since numbers can be repeated ; hence numbers do not have to be different ;

Number of digits between (0 - 49 inclusive) = 50 digits.

Thus, there are equal number of possible choices for each of the three numbers, which is equal to the Number of digits :

1st number = 50

2nd = 50

3rd = 50

Hence,

(50³). = 50 * 50 * 50 = 125,000

Answer:

The equation is y = [tex]-\frac{4}{3}[/tex] x + 3

Step-by-step explanation:

The form of the equation is y = m x + b, where

∵ The slope of the line is [tex]-\frac{4}{3}[/tex]

∴ m = [tex]-\frac{4}{3}[/tex]

→ Substitute it in the form of the equation above

∴ y =  [tex]-\frac{4}{3}[/tex] x + b

∵ The y-intercept = 3

∴ b = 3

→ Substitute it in the equation above

∴ y = [tex]-\frac{4}{3}[/tex] x + 3

∴ The equation is y = [tex]-\frac{4}{3}[/tex] x + 3

Answer:

Deal A is best

Step-by-step explanation:

Given

Deal A:

3/4 lb for $2.50

Deal B:

2/10 lb for $5.25

Required

Which deal is the better

To do this, we simply calculate the lb/dollar ratio

i.e.

[tex]Ratio = \frac{Amount}{Size}[/tex]

For Deal A:

[tex]Ratio = \$2.50/\frac{3}{4}lb[/tex]

[tex]Ratio = \$2.50 * \frac{4}{3}lb[/tex]

[tex]Ratio = \frac{\$10}{3}lb[/tex]

[tex]Ratio = \$3.33/lb[/tex]

For Deal B:

[tex]Ratio = \$5.25/\frac{2}{10}lb[/tex]

[tex]Ratio = \$5.25 * \frac{10}{2}lb[/tex]

[tex]Ratio = \frac{52.5}{2}lb[/tex]

[tex]Ratio = \$26.25/lb[/tex]

The better deal is the least expensive:

Hence: Deal A is better
