Answer:

630

Step-by-step explanation:

450 x 0.4 = 180

180 + 450 = 630

You can also do 450 x 1.4 = 630 because this will find the increased price with 140% of 450

The value of x is approximately (7√3) / 3.

Given that a right triangle with base = x and the perpendicular side = 7 and the reference angle is 60°, we need to find the value of x.

To find the value of x in a right triangle with a base of x and a perpendicular side of 7, and with a reference angle of 60 degrees, we can use the tangent function.

The tangent of an angle is defined as the ratio of the length of the side opposite the angle (in this case, 7) to the length of the side adjacent to the angle (in this case, x). So we have:

tan(60°) = 7 / x

Now, we can solve for x by multiplying both sides of the equation by x:

xtan(60°) = 7

To find the value of x, we need to know the value of tan(60°). The tangent of 60 degrees is √3. So we have:

x√3 = 7

To isolate x, we divide both sides of the equation by √3:

x = 7 / √3

To simplify the expression, we multiply both the numerator and the denominator by √3:

x = (7 / √3)(√3 / √3)

= (7√3) / 3

Therefore, the value of x is approximately (7√3) / 3.

and 1/2, 1,2,3,4 is neither

Step-by-step explanation:

Answer:

Step-by-step explanation:

a) Men = 4/9 × 27 = 12

Women = 7/12 × 60 = 35

Total =  35 + 12 = 47

b) 60 + 27 = 87

87 - 47 = 40

P(no glasses) = 40/87

The number of people in the choir who do not wear glasses is 40 and the number of people who wear glasses is equal to 47

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening being equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes.

Given here P(a man is wearing a glasses) = 4/9 and P(A woman wearing glasses)= 7/12

Now using the formula for probability and total man is 27 hence

P(man) = 4/9

            = 4× 3/9×3

            = 12/27

thus the number of men that wear glasses is equal to 12 and man who do not is 27-12=15

Similarly for woman P(woman) = 7×5/12×5

                                                   = 35/60

therefore woman who wear glasses = 35 and woman who do not = 25

Hence total number of people who wear glasses is 47 and people who do not wear glasses is equal to 40

Answer:

x = 20

Step-by-step explanation:

Each line creates a 180° angle on each side of it. Since these lines intersect, they have congruent angles. This means that these two quantities can be set equal to each other.

3x + 50 = 6x - 10

Solve by combining like-terms and isolating x. Move the 3x to the right by subtracting it from both sides.

50 = 3x - 10

Move the 10 to the left by adding it to both sides.

60 = 3x

Divide the 3 from both sides to isolate the x.

x = 20

Furthermore, this can be checked by plugging in 20 to x and seeing if the expression is true.

3(20) + 50 = 6(20) - 10

Answer: 67.5 mph

Step-by-step explanation:

The formula for speed is:

= Distance / Time

Distance = 658.125 miles

Time will need to be converted to a decimal. You may convert only the minutes into hours as the hours are already hours.

= 45/60 minutes

= 0.75 hrs

= 9 + 0.75

= 9.75 hours

Speed = 658.125 / 9.75

= 67.5 mph

The length of AD is 75. Since opposite sides have the same length, 63 plus 63 is 126. The perimeter is 276, so 276 minus 126 is 150. 150 divided by 2 is 75.

Q6) Amy is 4 years old right now

Step-by-step explanation:

Q5)

3(x+2) = 27

3x+6 = 27

subtract 6 from both sides

3x = 21

divide both sides by 3

x = 7

Q6)

P = Patel's age now

A = Amy's age now

P = A+5

P+1 = 2(A+1)

substitute for P

(A+5)+1 = 2(A+1)

reduce

A+6 = 2A+2

subtract (1)A and 2 from each side

A = 4

check:

P=A+5 = 9

9+1 = 2(4+1)

Answer:

[tex]18r+\frac{1}{2}(14)(r)=182[/tex]

Step-by-step explanation:

Area of the composite figure ABCDE = Area of triangle ABE + Area of the rectangle BCDE

Area of triangle ABE = [tex]\frac{1}{2}(32-18)(r)[/tex]

                                  = [tex]\frac{1}{2}(14)(r)[/tex]

Area of rectangle BCDE = 18 × r

                                        = 18r

Total Area = [tex]\frac{1}{2}(14)r+18r[/tex]

Therefore, equation to get the value of 'r' will be,

[tex]18r+\frac{1}{2}(14)(r)=182[/tex]
