Emma has received a 35 percent discount on the frame

A discount is a reduction in price of an item usually for promotion or marketing purposes.

A discount could be in the form of a percentage off the price of the item or a fixed amount(say $7) off the price of the item

In the case of Emma, he got a fixed amount off the price which we converted to percentage to determine the amount off. This is calculated thus:

discount price/price of item ×100/1

5.25/15×100/1= 0.35(35%)

If a percentage is used, a variable( can change)amount in the form of a discount is possible otherwise not.

Answer:

C

Step-by-step explanation:

Line pases through (6, 0) and (0, -6)

Slope = (0 - (-6))/(6 - 0) = 6/6 = 1

so y = 1*(x - 6) = x - 6

or x - y = 6

or 4x - 4y = 24

That is C

Answer: his is a simple as well as an interesting question. CASE I: y = 25. Consider this a² = |a|. Given y = 25, we can write like this way,. y = -5/2.

Step-by-step explanation:

Answer:

-1/2

Step-by-step explanation:

We are given the exponential equation:—

[tex]\displaystyle \large{125=(\frac{1}{25})^{y-1}}[/tex]

First, use a law of exponent [Quotient Rules] to convert RHS:—

[tex]\displaystyle \large{125=(25^{-1})^{y-1}}[/tex]

Then convert both bases to base 5:—

[tex]\displaystyle \large{5^3 = (5^{-2})^{y-1}}[/tex]

Use another law of exponent [Power] to multiply the exponent of RHS:—

[tex]\displaystyle \large{5^3 = 5^{-2y+2}}[/tex]

Now that both sides have same base, solve the equations with exponent:—

[tex]\displaystyle \large{3=-2y+2}\\\displaystyle \large{1=-2y}\\\displaystyle \large{y=-\frac{1}{2}}[/tex]

Therefore, the value of y is:—

[tex]\displaystyle \large{\boxed{-\frac{1}{2}}}[/tex]

Summary

This section includes an important or necessary explanation, summary or formulas that was used in the explanation above.

  Laws of Exponent

Power of Power Rules:—

[tex]\displaystyle \large{(a^m)^n = a^{mn}}[/tex]

Quotient Rules:—

[tex]\displaystyle \large{a^{-n}=\frac{1}{a^n}}[/tex]

Note that the above, Quotient Rules, is derived from:—

[tex]\displaystyle \large{\frac{a^m}{a^n} = a^m \div a^n = a^{m-n}[/tex]

But when m = 0 the numerator becomes 1.

  Exponential Equation

When solving an Exponential Equation, the goal is to convert both sides having the same base.

When both sides have same base, take both exponents of both sides to solve the equation.

Answer:

Given ,

Ahmed's age = " m " years.

Also ,

age of Ahmed's sister = 2 × m = 2m years

According to Question ,

age of ahmed + age of his sister = 27

[tex]\bold{m + 2m = 27 }\\ \bold{3m = 27 }\\ \bold{m = \cancel{\frac{27}{3} }} \\ \\ \fbox\blue{m = 9}[/tex]

therefore ,

age of Ahmed = 9 years.

age of Ahmed's sister = 2m = 2 ( 9 ) = 18 years.

hope helpful~

Age of Ahmed is 9 years

Age of Ahmad's sister is 18 years

In the question it is given that Ahmed is of m years.

Her sister is twice as old as he.

Now in the question it is given that sum of their ages is 27. So lets add the age of Ahmed and his sister and keep it equal to 27 inorder to get the value of m.

Age of Ahmed + Age of his sister = 27

m + 2m = 27

3m = 27

m = 27 / 3

m = 9

★ Age of Ahmed:-

Age of Ahmed = m

Age of Ahmed = 9 years

★ Age of his sister:-

Age of Ahmad's sister = 2m

Age of Ahmad's sister = 2 × 9

Age of Ahmad's sister = 18 years

What makes Europa a potential home to extraterrestrial life? *

Europa is the sixth closest moon of the planet Jupiter, and one of the largest moons in the solar system. Europa is slightly smaller than the Earth’s moon and has a tenuous atmosphere compared primarily to oxygen. The surface of Europa is composed of water and is one of the smoothest in the solar system. Scientists suggest that it is possible Europa has an ocean of liquid water beneath its surface, making it a strong candidate for extraterrestrial life. It is also predicted that heat energy from tidal flexing may cause oceans to remain liquid and drives geological activity similar to plate tectonics on Earth.

Answer:

60 kg of cement, 180 kg of sand and 240 kg of gravel

Step-by-step explanation:

x : 3x : 4x

If you turn this into an equation, it becomes x + 3x + 4x = 480

8x = 480

x = 60

60 is the amount for the cement, for the sand and gravel multiply this answer by 3 and the other by 4, you should get 180 and 240

Answer:

276 square inches

Step-by-step explanation:

The area can be decomposed as a square of side length 14 in, having a surface of area of [tex]14^2 = 196 in^2[/tex], and a triangle of base 14 and height 12, giving an area of [tex]\frac12\times 12\times14 =84 in^2[/tex]. Added them together we get a grand total of [tex]196+84=280 in^2[/tex]

Answer:

280 in²

Step-by-step explanation:

This is a composite figure composed of a triangle and a square. Let's find the area of each and add them up.

The area of the square is 196 square inches. The area of the triangle is 84 square inches. Add those two together, and you have 280 square inches.

Answer:

y=-2x-4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(2-(-16))/(-3-6)

m=(2+16)/-9

m=18/-9

m=-2

y-y1=m(x-x1)

y-(-16)=-2(x-6)

y+16=-2(x-6)

y=-2x+12-16

y=-2x-4

Answer:

Neither

Step-by-step explanation:

y2 - y1          -16 - 2           -18

----------   =   -----------   =   --------   =   2

x2 - x1          -3 - 6              -9

y = mx + b

-16 = 2(6) + b

-16 = 12 + b

-12   -12

-28 = b

y = 2x - 28

y = mx + b

2 = 2(-3) + b

2 = -6 + b

+6  +6

8 = b

y = 2x + 8

Answer:

  25√2 ≈ 35.36 inches

Step-by-step explanation:

The Pythagorean theorem can be used to find the leg length for the given conditions. It tells you the relation between legs a, b, and hypotenuse c is ...

  c² = a² +b²

If a=b, and c=50, this becomes ...

  50² = a² +a²

  1250 = a² . . . . divide by 2

  25√2 = a . . . . take the square root

The length of each leg is 25√2 ≈ 35.36 inches.

Answer:

220 square inches.

Step-by-step explanation:

You have to find the area of each fact on the rectangular prism and add them all up. There are two faces in the prism with each pair of side lengths, like two faces with side lengths of 4x5, two with 5x10, etc.

4x5 = 20 20x2 = 40

4x10 = 40 40x2 = 80

5x10 = 50 50x2 = 100

100 + 80 + 40 = 220 square inches

Answer:

B. 220 in ^2

To find the surface area, we have to find the area of each face and add them all together.

Let's get started.

Face one:

Let's start with the one facing us.

The width is 4

The length is 10

4 x 10 = 40

Since there is an identical face on the opposite side, we need two of those.

40 x 2 = 80

Now let's do the face facing to the right.

The length is 10

The width is 5

5 x 10 = 50

Since there is an identical face on the opposite side, we need two of those.

50 x 2 = 100

Now the one on the top

The length is 5

The width is 4

5 x 4 = 20

Since there is an identical face on the opposite side, we need two of those.

20 x 2 = 40

80 + 100 + 40 = 220

Answer:

Step-by-step explanation:

Answer:

<A =73

Step-by-step explanation:

The sum of the angles of a triangle are 180

<C is 90

<B is 17

We need to find <A

<A + < B + <C = 180

<A + 17+90 = 180

<A + 107 =180

<A = 180-107

<A =73
