Alice draws a triangle and measures two of the angles with a protractor. The angle measures are 65 and 45. Cal says the measure of the third angle is 60. Explain why Cal's answer is incorrect.

Answer:

Rs. 67800

Step-by-step explanation:

Price of photograph = 60000 = 100%

Tax = x dollars = 13% of 60000

100% + 13% = 113% = 1.13

Multiply

1.13(60000) = 67800

To check, lets find 13% of 60000 and add to 60000

13% = 0.13

0.13(60000) = 7800

60000 + 7800 = 67800

Units = Rs

Rs. 67800

57 = 30 × t

t = 57/30

t = 19 × 3 / 10 × 3

t = 19/10

t = 1.9

Answer:

t = 1.9

Step-by-step explanation:

Given

d = rt

Substitute d = 57 and r = 30 into the equation

57 = 30t ( divide both sides by 30 )

[tex]\frac{57}{30}[/tex] = t , that is

t = 1.9

Answer: x = 2

Step-by-step explanation:

4x + 4 = 2x + 8

2x = 4

x = 2

Answer: x = 2.

Step-by-step explanation: 4x+4=2x+8 subtract 4 from both sides.

4x = 2x+4 subtract 2x on both sides

2x = 4        divide both sides by two

x = 2

Answer:

50

Step-by-step explanation:

The median number is known as the middles number

The first step is to rearrange the set of numbers starting from the lowest

25, 32, 32, 32, 33, 40, 47, 47, 48, 55, 56

Hence the middle number is 50

Answer:

x=5      x=1

Step-by-step explanation:

To find the x intercepts, set y=0

(x-5) (x-1) =0

Using the zero product property

x-5 =0   x-1 =0

x=5      x=1

Answer:

The angle SQR is half the intercepted arc SR which is 43°

3x - 6 = 90

3x - 6 + 6 90 + 6

3x = 96

3x ÷ 3 = 96 ÷ 3

x = 32

Answer:

5√3

Step-by-step explanation:

Thanks to the given information we can say that the smallest leg is 5 because the triangle is half of an equaliteral one.

for the same reason we can say that x is 5√3 that is the simplest from of the result of the Pytaghorean theorem

Answer:

[tex]\frac{59}{300}[/tex]

Step-by-step explanation:

Recall that [tex]\frac{x}{9}[/tex] returns the decimal [tex]0.\overline{x}[/tex]. In this case, we only want the 6 repeating. We can achieve this by finding the fraction excluding the 6 and then adding the repeating fraction with the 6.

0.19 as a fraction is simply [tex]\frac{19}{100}[/tex]

[tex]\frac{6}{9}[/tex] returns a repeating digit 6. However, we would like the 6 to be in the thousands place. Since it's already in the tenth place, we will divide the fraction by 100 to put it in the thousands place: [tex]\frac{6}{9}\cdot \frac{1}{100}=\frac{6}{900}[/tex]

Adding these two fractions, we get:

[tex]\frac{6}{900}+\frac{19}{100}=\frac{6}{900}+\frac{171}{900}=\frac{177}{900}=\boxed{\frac{59}{300}}[/tex]

66/3.3

it's twenty i dont know what else to say

Answer:

20m

Step-by-step explanation:

1m = 3.3ft

66 feet = 20m

If the digit after tenth is greater than or equal to 5, add 1 to tenth. Else remove the digit. Example

124.58

The first number of right of decimal point is 5

The second digit after decimal point is 8 which is greater than 5

So add 1 to 5

Result = 124.6

no answer just explanation,

The solution to the quadratic equation x² - 4x + 1 = 0 is x = ( 4 ±√12 ) / 2

A quadratic equation in its standard form is expressed as;

ax² + bx + c = 0

Where x is the unknown

To solve for x, we use the quadratic formula

x = (-b±√(b² - 4ac)) / (2a)

Given the quadratic equation in the question;

x² - 4x + 1 = 0

We substitute this values into the quadratic formula above and solve for x.

x = (-b±√(b² - 4ac)) / (2a)

x = ( -(-4) ±√( (-4)² - ( 4 × 1 × 1)) / (2 × 1)

x = ( 4 ±√( 16 - 4) ) / (2)

x = ( 4 ±√12 ) / 2

Therefore, ( 4 ±√12 ) / 2 is the solution to the equation.

Option C) ( 4 ±√12 ) / 2 is the correct answer.

Answer: the answer is 375.5906

Step-by-step explanation:

Answer:

7) [tex]x \to x - 3[/tex].

8) [tex]y \to y + 2[/tex]

9) The entire quadratic equation did not get reflected.

Step-by-step explanation:

7) A horizontal translation to the right is of the form:

[tex]x \to x - a[/tex]

Let [tex]y = -(x-3)^{2} + 2[/tex], then the horizontal translation is represented by [tex]x \to x - 3[/tex].

8) A vertical translation upwards is of the form:

[tex]y \to y + a[/tex]

Let [tex]y = -(x-3)^{2} + 2[/tex] , then the vertical translation is represented by:

[tex]y \to y + 2[/tex]

9) The only component of the quadratic equation that was reflected was the part [tex](x-3) ^{2}[/tex] along the x-axis. We can create the entire function by applying the following steps:

(i) [tex]f(x) = x^{2}[/tex] (Original function)

(ii) [tex]f(x) = (x-3)^{2}[/tex] (Horizontal translation)

(iii) [tex]f(x) = - (x-3)^{2}[/tex] (Reflection)

(iv) [tex]f(x) = -(x-3)^{2} + 2[/tex] (Vertical translation)

The entire quadratic equation did not get reflected.

Answer:

3=0.5p

Step-by-step explanation:

The cost to get a small sundae with P toppings added represented  as 3 + 0.5p.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Let's consider the toppings added to the chocolate sundae represented by p.

We will use the unitary method,

The cost of topping added to one chocolate = $0.50

The cost of topping added to p chocolate = $0.5p

So, the cost to get a small sundae with P toppings added is;

3 + 0.5p

Therefore, the cost to get a small sundae with P toppings added represented  as 3 + 0.5p
