can somebody plsss help me with these 2 questions

Answer:

Solution :

Selling price (S.P) = (100 + m)% ⋅ C.P

Here,

M = 35, C.P =40$

Then,

S.P = (100 + 35)% ⋅ 40

S.P = 135% ⋅ 40

S.P = 1.35 ⋅ 40

S.P = 54

So, the selling price is $54.

Answer:

Step-by-step explanation:

Given:

Find the mark up price:

Answer:

41. s = semiperimeter

s = (a + b + c) /2

s = (120+170+250) /2

s = 270m

d is the correct option.

42. b is the correct option.

43. P = a + b + c

P = 120+170+250

P = 540m

a is the correct option.

44. A = √s((s-a)(s-b)(s-c))

=√270((270-120)(270-170)(270-250))

=9000m²

d is the correct option.

45. length of wire=P - space for gate

= 540 - 3

=537m

b is the correct option.

Answer:

k = 5

Step-by-step explanation:

The formula for coefficient of proportionality is y = kx.

In the given problem, the Area of a rectangle corresponds to "y" in the constant of proportionality formula, and "x" is still the same. Since the formula for the area of a rectangle is: A = L × W, then:

A = y

L = k

W = x

y = kx is the same as A = LW or A =  L × W

Thus, we're looking for the value for k, which corresponds to the length (L) (which has a constant value).

Below are the calculations for the missing values in the table:

We'll start with x = 0.14, and A = 0.7 since we're given the values for them. We could plug these values into the formula for the Area of a rectangle to find the constant value of the length (L):

A = L * W

0.7 = L * 0.14

Divide both sides by 0.14 to isolate L:

0.7/0.14 = (L * 0.14)/0.14

5 = L  ←← Keep in mind, this is the coefficient of proportionality.

x = 3.1:

A = L * W

A = 5 * 3.1

A = 15.5

x = 2.5:

A = 5 * 2.5

A = 12.5

x = 1.2:

A = 5 * 1.2

A = 6

x = 0.9:

A = 5 * 0.9

A = 4.5

Next, we're given the values for the Area, but we're missing the values for x. However, we already have the value for L = 5. We could still follow the same process by plugging in the values into the formula:

A = 0.3:

A = L * W

0.3 = 5 * W  

Divide both sides by 5 to solve for W:

[tex]\frac{0.3}{5} = \frac{5 * W}{5}[/tex]

0.06 = W

A = 0.1:

A = L * W

0.1 = 5 * W  

Divide both sides by 5 to solve for W:

[tex]\frac{0.1}{5} = \frac{5 * W}{5}[/tex]

0.02 = W

Therefore, k = 5.

Answer:

4.4...

Step-by-step explanation:

20 ÷ 4 1/2

let's change 4 1/2 into an improper fraction.

20 ÷ 9/2

20 is the same thing as 20/1, so we'll express it that way.

[tex]\frac{20}{1}[/tex] ÷ [tex]\frac{9}{2}[/tex]

in order to divide fractions, you must multiply the first number (20/1) by the inverse of the second number (2/9). I'll put it in normal fraction form for clarity.

20      2

---   ×  ---

1          9

now we multiply straight across.

40

----

9

now we have 40 ÷ 9, which is 4.444...

so your answer is 4.4...

Use the distributive property: Multiply -3 by (2x-5), and 5 by (2-x):

[tex]-6x+15<10-5x[/tex]

Subtract 15 from both sides:

Answer:

x= -3.6

y= -2.8

Step-by-step explanation:

9x +17 =3x-5 ( interior angles are equal)

9x-3x +17= 3x-3x -5

6x+ 17+ 5= -5+5

6x/6= -22/6

x= -3.6

3x-5= 6y+1 ( vertical angles)

3(-3.6) -5 = 6y+ 1

-10.8 -5 -1= 6y +1 -1

-16.8 = 6y

-16.8/6 = 6y/6

Step-by-step explanation:

Answer:

In particular, for an expression to be a polynomial term, it must contain no square roots of variables, no fractional or negative powers on the variables, and no variables in the denominators of any fractions.

So I'd say a polynomial is a finite sum of terms in which all variables have whole number exponents and no variable appears in a denominator. The leading term in a polynomial is the term of highest degree. The constant term in a polynomial is the term without a variable.

Answer:

Money decrease = $58.21

Total Bill = $159.79

Step-by-step explanation:

Starting Value = $218

Percent Decrease = 26.7%

End Value = x

Value Decrease = $218 - x

x = 1(218) - 0.267(21.8)

x = 0.733(218)

x = 159.794 ≈ $159.79

Money Decrease = $218 - $159.79 = $58.21

Total Bill = $159.79

-Chetan K

The amount by which the text book decrease is $58.206

The total textbook bill for the term is $ 159.794

The first step is the calculate the amount by which the textbook decreased

The formular can be written as

Decrease= original amount × percentage decrease

= 218 × 26.7/100

= 218 × 0.267

= 58.206

The amount by which the textbook decreased is $58.206

The total textbook bill for the term can be calculated as follows

= Original amount- amount decrease

= 218 - 58.206

= 159.794

The total textbook bill for the term is $159.794

Answer:

Step-by-step explanation:

Answer:

5/14

Step-by-step explanation:

The probability of drawing a particular coloured card is the number of cards that are that colour, divided by the total number of cards:

The probability of drawing a blue card on your first draw would be 5 out of (5 + 3) = 5/8

The next draw would be the same principle, but the denominator (bottom number of the fraction) would be 1 less, because you have just taken out 1 card on your first draw:

The probability of drawing a blue card on your second draw (after drawing a blue card first) would be 4 (since you have already taken one) out of (8 - 1) = 4 / 7

To find the probability of both these steps combined, you multiply the two fractions together:

5/8 x 4/7 = 20/56

The question asks you to simplify, which means that the final answer is 5/14

Answer:

14.4

Step-by-step explanation:

Because the figures are similar, they are basically the same figure. One is just dilated by a certain amount. To figure out the missing x, we need to find out exactly how much the small one is dilated from the bigger one.

Here's how we do that:

We know 9 and 5 are correlating sides because of where they are in relation to the right angle. We can find out how much smaller 5 is than 9 by dividing 9 by 5.

9 ÷ 5 = 1.8

This means that x is going to be bigger than 8 by a multiple of 1.8.

8 × 1.8 = x

14.4 = x

Answer:

-17/12 = -1  5/12

Step-by-step explanation:

1/3-7/4=

*find a common denominator

*multiply the first fraction times 4 and the second one times 3

4/12- 21/12

-17/14

The addition of the fractions is determined as  [tex]\frac{1}{3}+\frac{-7}{4}=\frac{-17}{12}[/tex].

Given data:

To add the fractions 1/3 and -7/4, we need to find a common denominator. The least common multiple of 3 and 4 is 12. So, we will rewrite both fractions with a denominator of 12:

1/3 = (1/3) * (4/4) = 4/12

-7/4 = (-7/4) * (3/3) = -21/12

Now, we can add the fractions:

[tex]\frac{1}{3}+\frac{-7}{4}=\frac{4}{12}+\frac{-21}{12}[/tex]

[tex]= \frac{(4 - 21)}{12 }[/tex]

[tex]=\frac{ -17}{12}[/tex]

The result is [tex]\frac{ -17}{12}[/tex] . This fraction is already in its simplest form, meaning the numerator and denominator do not share any common factors other than 1.

In simpler terms, when we add 1/3 and -7/4, we first find a common denominator of 12. Then, we rewrite the fractions with that denominator and add them.

Hence, the fraction is [tex]\frac{ -17}{12}[/tex].
