Answer:the discount was $16.80

Step-by-step explanation:

Discount=30% of original price

=0.3X$56

=16.80

The discount was $16.80 in dollars and cents

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that Zachary bought some belts online for $56. He used a coupon code to get a 30% discount.

Given the website also app lied a 15% processing fee to the price after the discount.

Discount = 30% of original price

= 0.3 x $56

=16.80

Answer:

352 sq. inches

Step-by-step explanation:

32 x 22 = 704

704 / 2 = 352

Answer:

352 sq. inches

Step-by-step explanation:

The area of a triangle is found by the formula 1/2bh

aka 1/2 of base times height

the height is 22 and the base is 32 so we multiply 22 by 32

We get 704 but not the end we have to multiply that by 1/2 or divide by 2

Do that and you get 352

b=32      h=22

22*32=704

704/2 or 704*1/2 = 352

Answer:

[tex]x = 13.8[/tex]

Step-by-step explanation:

Given

See attachment for triangle

Required

Find x

To find y, we make use of the relationship between sides lengths 11 & x and angle 37

The relationship is:

[tex]cos(37) = \frac{11}{x}[/tex]

i.e.

[tex]cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]

Make x the subject

[tex]x = \frac{11}{cos(37)}[/tex]

[tex]x = \frac{11}{0.7986}[/tex]

[tex]x = 13.7741[/tex]

[tex]x = 13.8[/tex] -- approximated

Answer: $329.05

Step-by-step explanation:

Since she pays $245.82 monthly and she is paying for 6 months, the amount paid will be:

= $245.82 × 6

= $1474.92

Since she buys the full golf club set for $1,145.87, then her finance charge will be:

= $1474.92 - $1,145.87

= $329.05

The finance charge is $329.05

Answer:

1/4x = 27

Step-by-step explanation:

Given the equations :

1.)

1/4x = 27 ;

x/4 = 27

x = 27 * 4

x = 108

2.)

3x = 36

Divide both sides by 3

x = 36/3

x = 12

3.)

3/4x = 9

3x / 4 = 9

3x = 9*4

3x = 36

x =. 36/3

x = 12

4. 4x = 48

x = 48/4

x = 12

All other equations equal to 12 except (1)

Answer: 3 L

Step-by-step explanation:

Given

Grace uses 1000 mL of apple Juice to make one batch of fruit punch

If she triples the recipe, then the Juice used is also tripled i.e.

[tex]\Rightarrow 3\times 1000=3000\ mL[/tex]

In littres, it is [tex]3000\ mL=3\ L[/tex]

Step-by-step explanation:

Dilations do not change your angles, so although the length does change, your angles will not. So for your answer, the angles will be the exact same.

For the length, all you have to do is multiply each side by 5/2.

8: Multiplied by 5/2 is 20

9: Multiplied by 5/2 is 22.5

7: Multiplied by 5/2 is 17.5

The lengths are getting larger because they're being dilated by a number greater than 1.

I hope this helps :)

Answer:

Answers bellow hope I helped

Step-by-step explanation:

A)Each angle is the SAME becouse we are just making the triangle larger but the angles stay the same so:

Z' = 50°

X' = 70°

Y' = 60°

B)You have to multiply each of the sides by your scale factor so:

Side X'Y' = 7 x 5/2= 17.5

Side X'Z' = 8 x 5/2 = 20

Side Z'Y' = 9 x 5/2 = 22.5

Step-by-step explanation:

Answer:

Actual                                      2/3

30 inch. by 12 inch               240 inch²

30 inch. by 18 inch               360 inch²

12 inch. by 15 inch                  120inch²

18 inch. by 15 inch                 180inch²

Step-by-step explanation:

The answers are given in the same line .

Actual                                                      1/3                          2/3

30 inch. by 12 inch                                120 inch²                 240 inch²

30 inch. by 18 inch                                180 inch²                 360 inch²

12 inch. by 15 inch                                  60 inch²                  120inch²

18 inch. by 15 inch                                90 inch²                    180inch²

We  find the areas and multiply by 2/3 to get the answers

30 * 12= 360 inch²

2/3 * 360 = 240 inch²

30 * 18= 540 inch²

2/3 * 540 = 360inch²

12 * 15= 180 inch²

2/3 * 180 = 120 inch²

18 * 15= 270 inch²

2/3 * 270 = 180inch²

Answer:

Step-by-step explanation:

The square root is possible only if y≤0

if y>0 the expression lose meaning, in fact (-)(+)(+) = (-) and a square root of a negative number doesn’t exist. x^2 is a square so it is ever positive if x is not 0

if y≤0 can be rewritten as:

3(-27x^2y^7)^1/2

or if we want simplify the expression:

[tex]3 \sqrt{3^2 * (-3) * x^2 * y^6 * y} = 3^2|x||y|^3 (-3y)[/tex] ^1/2

we have to put the symbol of absolute value between x and y because a x^2 and y^6 are numbers that are ever positive, while x and y^3 can be also negative. Thanks to the simbol of absolute value we can “force” them to be positive
