Answer:

AAS

Step-by-step explanation:

Answer:

Angle-side-angle is a rule used to prove whether a given set of triangles are congruent.

The ASA rule states that:

If two angles and the included side of one triangle are equal to two angles and included side of another triangle, then the triangles are congruent.

Angle-Angle-Side (AAS) Rule

Angle-side-angle is a rule used to prove whether a given set of triangles are congruent.

The AAS rule states that:

If two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.

In the diagrams below, if AC = QP, angle A = angle Q, and angle B = angle R, then triangle ABC is congruent to triangle QRP.

Answer:

[tex]-8a^{7b}[/tex]

Step-by-step explanation:

[tex](-4 a^{5b}) (2a^{2b}) = -(2^2 a^{5b}) (2a^{2b})\\[/tex]

                    [tex]= -(2 ^2 \times 2) \times a^{5b + 2b}\\\\= -(2 ^{2+1}) \times a^{7b}\\\\=-(2^{3}) \times a^{7b}\\\\= - 8 a^{7b}[/tex]

Answer:

$19.99

Step-by-step explanation:

There are 12 months in a year, so in 2 years, there are 24 months.

Find how much each payment will be by dividing the cost by 24:

479.76/24

= 19.99

So, each payment will be $19.99

it would be 10

Step-by-step explanation:

once you solve the problem which should equal up to 3000 then you would divide 30000÷3000 and get the answer of 10

Answer:

The yellow trapezoid, blue rectangle, and whatever that purple thing is are zingoes

Step-by-step explanation:

As far as I can tell, all the correct examples are

1) Symmetrical

2) Have a line splitting them symmetrically and does not go above or below the shape (Does that make sense?)

The wrong examples don't have any of the characteristics told above. For example, the square would be wrong because it doesn't even have a line

(P.S- This isn't my picture, just found it on the web. Shout out to whoever owns this)

1011₂ + 10111₂

= (1000₂ + 10₂ + 1₂) + (10000₂ + 100₂ + 10₂ + 1₂)

= 10000₂ + 1000₂ + 100₂ + 2 (10₂) + 2 (1₂)

= 10000₂ + 1000₂ + 100₂ + 2 (10₂) + 10₂

= 10000₂ + 1000₂ + 100₂ + 100₂ + 10₂

= 10000₂ + 1000₂ + 2 (100₂) + 10₂

= 10000₂ + 1000₂ + 1000₂ + 10₂

= 10000₂ + 2 (1000₂) + 10₂

= 10000₂ + 10000₂ + 10₂

= 2 (10000₂) + 10₂

= 100000₂ + 10₂

= 100010₂

Step-by-step explanation:

Answer:

The total discount is 51%.

Step-by-step explanation:

A 30% discount is applied to the price of a product and another 30% discount to the new price. What is the total discount?

Let the price is p.

After first discount, the price is

= 70% of p = 0.7 p

After second discount, the price is

= 70% of 0.7 p

= 0.7 x 0.7 p

= 0.49 p

So, let the total discount is d.

[tex]d = \frac{p - 0.49 p}{p}\times 100 = 51%[/tex]

Answer:

Its a rectangle.

Step-by-step explanation:

After graphing the points, we can quickly figure out it cant be a square.

Then, when we draw the sides, we see it has to be a rectangle, since each side has a perfect 90 degree angle, and the opposite side lengths are parrelel.

Answer:

Step-by-step explanation:

Answer:

$480

Step-by-step explanation:

multiply the normal price $600 by 20 then divide it by one hundred

the discount is $120

the sales price is subracting the discount of $120 from the original price of $600 then get $480 as the sales price.

Answer:

Step-by-step explanation:

Method 1:  Subtract 20% from 100%, obtaining 80%, and then multiply the regular price ($600) by the decimal equivalent 0.80.  We get $480 as the sale price.

Method 2: Calculate the amount of the discount by multiplying $600 by 0.20, obtaining $120.  Then subtract this discount from the regular price, $600, obtaining $480.

Answer:

210

Step-by-step explanation:

Lets use BEDMAS (Brackets, Exponents, Division, Multiplication, Addition, Subtraction)

45 ÷ 2 = 22.5

22.5 × 8 = 180

180 - 12 = 168

168 + 42 = 210

Answer:

Step-by-step explanation:

given.quesion.

The length of a rectangle is decreased by 25% and the width has increased by 40% calculate the percentage change in the area of the rectangle

to. find.

area of the rectangle

given

decreased. 25•/•

increased.40•/•

solusion

Length = L

Breadth = B

Original area = L x B

New area = A = L x (1 - 25%) x B x (1 + 40%)

A = L x B x 0.75 x 1.40 = L x B x 1.05

Therefore the area of the rectangle has increased by 5%.

Answer: 9/4

Step-by-step explanation: Think of [tex](\frac{4}{9})^{-1}[/tex]as [tex]\frac{4^{-1} }{9^{-1}}[/tex].

Now, we can change 4⁻¹ to 4¹ by moving it to the denominator and

we can change 9⁻¹ to 9¹ by moving it to the numerator.

So we have 9¹/4¹ which simplifies to 9/4.

Answer:

Step-by-step explanation:

perimeter of rectangle=a+b+c

=3x+3x+15

=6x+15

if perimeter of rectangle is 90,

perimeter=a+b+c

90=3x+3x+15

90-15=6x

75/6=x

12.5=x

Answer:

X=12.5

Step-by-step explanation:

3x+3x+15

If it equalls 90 then write it as 6x+15=90

Now isolate X.

6x+15=90

6x=75

x=12.5

Step-by-step explanation:

x = root under 5/2

so it is real and irrational number

Given:

A figure of a rectangular prism with length l, width w and height h.

To find:

The surface area of the rectangular prism.

Solution:

The product of twice of the length l and the width w is:

[tex]2\times l\times w=2lw[/tex]          ...(i)

The product of twice of the length l and the height is:

[tex]2\times l\times h=2lh[/tex]           ...(ii)

The product of twice of the width w and the height h is:

[tex]2\times w\times h=2wh[/tex]       ...(iii)

The surface area of the prism is the sum of (i), (ii) and (iii). So, the expression for the surface area is:

[tex]A=2lw+2lh+2wh[/tex]

[tex]A=2(lw+lh+wh)[/tex]

Therefore, the required expression is [tex]2(lw+lh+wh)[/tex].
