in an isosceles right triangle, the ratio of the measure of the angles is 1:1:2

Answer:

81

Step-by-step explanation:

Round 63.6 to 64

Round 102.3 to 102

Multiply 64 × 102=6528

Square root 6528 to get 80.796

Round 80.796 to 81

The estimate square root value of 63.6 x 102.3 is 81

What is an Equation?

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.

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 data ,

Let the equation be A

The value of A is

A = square root of 63.6 x 102.3

A = √63.6 x 102.3

Now , the value 63.6 can be approximated as 64

And the value 102.3 can be approximated as 102

So , the equation becomes

A = √ ( 64 x 102 )

A = 8 x √102

A = 8 x 10.099

A = 80.79

The value of A can be approximated as

A ≈ 81

Therefore , the value of A is  81

Hence , The estimate square root value of 63.6 x 102.3 is 81

Given:

Cost of an item with VAT = Rs 1,356

Cost of that item without VAT = Rs 1,200.

To find:

The VAT.

Solution:

We have,

Cost of an item with VAT = Rs 1,356

Cost of that item without VAT = Rs 1,200.

We know that,

VAT = Cost of an item with VAT - Cost of that item without VAT

       = 1356 - 1200

       = 156

Therefore, the value of VAT is $156.

Answer:

Pink Starburst occupies 20% of the total bag space

Step-by-step explanation:

Given

Ratio of pink (P) starburst to yellow (Y) starbursts [tex]= 0.25[/tex]

Mathematically, it can be written as

[tex]\frac{P}{Y} = 0.25\\Y = \frac{P}{0.25} \\Y = 4P[/tex]

Then the % space taken by pink startburt is equal

[tex]\frac{P}{4P + P} \\= \frac{P}{5P}\\= \frac{1}{5}\\= 0.2[/tex]

Hence, Pink Starburst occupies 20% of the total bag space

Answer:

PART 1

1) BC = AD = 16.4

2) CD = AB = 13.9

because JKMN is a parallelogram

=> KJ = ML

<=> y + 3 = 2y - 1

<=> y = 4

we also have: KL = JM

<=> 3x + 5 = 4x

<=> x= 5

3) with y = 4 => JK = 4 + 3 = 7

4) with x = 5 => KL = 3.5 + 5 = 20

PART 2

5) W = Y = 112⁰

6) Z = 180⁰ - 112⁰ = 68⁰

ABCD is a parallelogram

=> A + B = 180⁰

<=> 2y + 4y = 180

<=> y = 30

we also have:

C + D = 180⁰

<=> x + 5x - 180 = 180

=> x = 60

7) with y = 30 => A = 2.30 = 60⁰

8) with x = 60 => D = 5.60 - 180 = 120⁰

PART 3

9) EG = 2.HG = 2.14 = 28

10) DH = 1/2.DF = 20/ 2 = 10

QRSP is a parallelogram

=> 2y + 2 = 2x

x + 9 = 2y

=> x = 11

y = 10

11) with x = 11 => RT = 11 + 9 = 20

12) QS = 2.ST = 2.2.11 = 44

I got 7%

Step-by-step explanation:

110 x .15 = 16.5

110-16.5=93.5

93.5 x .10 = 9.35

93.5 + 9.35= $102.82

Thats the discount price

110 - 102.82 + 7.18

7.18/102 = .0698

Answer:

The answer is -6, -4

Step-by-step explanation:

The coordinates of F' are (-6, -4).

Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.

A transformation known as a translation involves moving each point in a figure uniformly and in the same direction.

Given:

Triangle DEF is reflected over the y-axis to form triangle D'E'F'.

now, we have the rule for reflection over y axis

P( x, y)-----> P' (-x, y)

Then the coordinates of D'E'F are

D(4, 1)---------> D'(-4, 1)

E(8, -3)---------> E'(-8, -3)

F (6, -4)----------> F'(-6, -4).
