Answer:

A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. The side opposite the obtuse angle in the triangle is the longest.

Answer:

30% profit

Step-by-step explanation:

The amount by which the shopkeeper reduced the advertised selling price = 20%

The resulting profit over the cost price = 4%

Let x represent the initial advertised selling price, and let y represent the new selling price, and let c represent the cost price, we have;

x - 20% of x = y

x - x × 20/100 = y

0.8·x = y

y = c + 4% of c = 1.04·c

∴ 0.8·x = 1.04·c

x = 1.04·c/0.8 = 1.3·c

x = 1.3·c = c + 0.3·c = c + 30% of c

x = c + 30% of c

From which we have that the initial advertised selling price, x = The cost price + 30% of the  cost price

Therefore, the initial advertised selling price = The cost price + 30%profit on   cost price.

The shopkeeper would have made 30% profit if the dress had then been sold at the original selling price.

Answer:

x=5

EF = 22in.

Step-by-step explanation:

We know EF and DE are equal, so we can solve for x.

5x-3=3x+7

5x-3x=7+3

2x=10

x=5

Now we plug that into EF.

EF = 3x+7 = 3(5)+7 = 15+7=22

Answer:

1.) 9.32

2.) 4.82

Step-by-step explanation:

neat trick i learned that really helps: SOH-CAH-TOA

Sine (opposite, hypotenuse), Cosine (Adjacent, Hypotenuse), Tangent (Opposite, Adjacent)

1.)

sin(21) = x/26    <----------- multiply by 26 to get x by itself

26*sin(21) = x  <----------- multiply 26 by sin(21)

9.32 = x      <------ rounded answer

2.)

cos(64) = x/11      <------------ multiply by 11 to get x by itself

11*cos(64) = x      <---------------- multiply 11 by cos(64)

4.82 = x      <-------- rounded answer

12=12

OR

8s-12=3s+3

5s-12=3

5s=15

s=3

Answer:s=3

Step-by-step explanation:

So the first thing that you do is the distributive property on both sides and then you combine like terms. After that you put the variable all on on side consonants. Then you divide and you get s.

Answer:

7

Step-by-step explanation:

Answer:

5

Step-by-step explanation

2 + 5 is 7 which equals 1 person 7 x 5 = 35 which means their will be 5 people per group because 30 {room cost} plus 35 is 65

what do i mean?

2 + 5 IS 1 person and 2 plus 5 is 7 so the remaining money they have would be 35 because 65 minus 30 is 35 so i divid 35 by 7 which brings 5 people

Answer: 23

Step-by-step explanation:

Answer:

$22.50

Step-by-step explanation:

if 3 bags of cat food = 13.50, divide 13.5 by 3 to get the cost of one bag, which is $4.50.

since hes getting 5, we can use 13.50 once and then the price of one bag (4.5) twice for the other two.

so that would be 13.5 + 4.5 + 4.5 = $22.50

hope this helped :)

Answer:

cost of three bags of cat food = 13.50

cost of 1 cat food = 13.50/3 = 4.50

cost of 5 cat food = 4.50*5 = 22.5

Answer:

ITS B !!!!!!!!!!!!!

Step-by-step explanation:

The equivalent expression is -9/4 ÷ (-2/3).

Option B is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Negative 2 and one-fourth divided by negative two-thirds.

This can be written as,

-2(1/4) ÷ (-2/3)

= -9/4 ÷ (-2/3)

= -9/4 x -3/2

= 27/8 _____(A)

Now,

StartFraction 9 over 4 EndFraction divided by three-halves

This can be written as,

9/4 ÷ 3(1/2)

= 9/4 x 2/7

= 18/28 ______(1)

Negative StartFraction 9 over 4 EndFraction divided by (negative two-thirds)

This can be written as,

-9/4 ÷ (-2/3)

= -9/4 x -3/2

= 27/8 ______(2)

Negative StartFraction 9 over 4 EndFraction divided by two-thirds

This can be written as,

-9/4 ÷ 2/3

= -9/4 x 3/2

= -27/8

StartFraction 9 over 4 EndFraction divided by (negative three-halves)

This can be written as,

9/4 ÷ -3(1/2)

= 9/4 x 2/7

= 18/28

Thus,

From (A) and (2),

-9/4 ÷ (-2/3) is the equivalent expression.

Answer:

63.6 m^2

Step-by-step explanation:

A = (3.142)(4.5 m)^2

A = 63.6 m^2

Answer:

x = 18/25, y = -198/25

Step-by-step explanation:

Given the system of equations:

2x – y = 13x

-3x + 2y= -18

You can combine these two equations effectively by multiplying the first equation by 2, and adding because -2y and 2y will cancel out when added. So you will be left with only x terms

( 2x - y = 13x ) × 2

+ -3x + 2y = -18

________________

2(2x) - 3x + 2(-y) + 2y = 2(13x) - 18

4x - 3x - 2y + 2y = 26x - 18

x + 0 = 26x - 18

x = 26x - 18

________________

[Then use the properties of equality to simplify the expressions in the equation to derive the value of x]

x - x = 26x - 18 - x (subtraction property of equality)

0 = 25x - 18

0 + 18 = 25x - 18 + 18 (addition property of equality)

18 = 25x

18 / 25 = 25x / 25 (division property of equality)

18 / 25 = x

x = 18 / 25 (symmetric property of equality)

_______________

Now with the value of x, we can find the value of y by substituting the value of x into the variables of the top equation {2x – y = 13x} because this involves the simpliest steps.

Given x = 18 / 25.

2x – y = 13x → 2x – y + y = 13x + y → 2x = 13x + y → 2x – 13x = 13x + y – 13x → -11x = y → y = -11x.

Now that we know y = -11x, y = -11(18/25) which is - (11 × 18) / 25 = -198/25
