Answer: 6.4cm

Step-by-step explanation:

The area of a trapezoid is given as:

= 1/2(a + b)h

We then slot the given values into the formula. This will be:

1/2(15.8 + b) × 7.3 = 81.03.

7.3(15.8 + b)= 81.03 × 2

7.3(15.8 + b) = 162.06

115.34 + 7.3b = 162.06

7.3b = 162.06 - 115.34

7.3b = 46.72

b = 46.72/7.3

b = 6.4

Therefore, the answer is 6.4cm.

Answer:

x = 5+6y

Step-by-step explanation:

Let x represents the age of the father and  y represents the present age of the son.

ATQ,

The present age of  the father is 5 more than 6 times the  age of the son. We can write it in the form of equation as follows :

6 times the  age of the son means 6y. So,

x = 5+6y

Hence, the mathematical equation is "x = 5+6y".

Answer:

245 [tex]cm^{3}[/tex]

Step-by-step explanation:

Formula for volume:  [tex]a^{2}[/tex] [tex]\frac{h}{3}[/tex]

a = base edge

Base edge = 7

h = height

Height = 15

So, [tex]7^{2}[/tex] × [tex]\frac{15}{3}[/tex] = 245 [tex]cm^{3}[/tex]

Answer:

Option c.

Step-by-step explanation:

Using the normal curve to approximate a sampling distribution:

For a sample size n and a proportion n, the normal curve can be used if:

[tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

Option a:

[tex]np = 35*0.8 = 28 > 10[/tex]

[tex]n(1-p) = 35*0.2 = 7 < 10[/tex]

So option a cannot be used.

Option b:

[tex]np = 65*0.9 = 58.5 > 10[/tex]

[tex]n(1-p) = 65*0.1 = 6.5 < 10[/tex]

So option b cannot be used.

Option c:

[tex]np = 65*0.8 = 52 > 10[/tex]

[tex]n(1-p) = 65*0.2 = 13 > 10[/tex]

So option c can be used, and is the answer

Option d:

[tex]np = 35*0.9 = 31.5 > 10[/tex]

[tex]n(1-p) = 35*0.1 = 3.5 < 10[/tex]

So option d cannot be used.

The answer is given by option c.

Answer:

  £246

Step-by-step explanation:

James works 8:30 -2:00 = 6: 30 hours on Thursday and Friday, for a total of 2×6:30 = 13:00 hours.

James works 5 hours on Saturday, but gets paid for 5×(1 1/2) = 7.5 hours. Then for the three days, he gets paid for 13 +7.5 = 20.5 hours.

James's total pay for the three days is ...

  (20.5 h)(£12/h) = £246 . . . . pay for 3 days

_____

Additional comment

The associative property of multiplication says you can associate the factor 1 1/2 either with the hours or the pay:

  (5 h)((1 1/2)(£12/h)) = ((5 h)(1 1/2))(£12 /h)

The computation involving "time and a half" often calculates the pay separately for overtime hours. I sometimes find it easier to calculate the pay for overtime by increasing the hours, rather than the pay.

Answer:

23.9425 (Round if needed)

Step-by-step explanation:

This is 2 half circles so you can find the area of a circle and divide it by 2.

First circle has a diameter of 6 cm

6/2=3 cm

So, circle has radius of 3.

Area of circle= 3.14(pi) radius^2

3.14 x 3^2= 28.26

28.26/2=14.13 cm

Area of first half circle= 14.13

Repeat that process for the second circle.

3.14 x 2.5^2=19.625

19.625/2=9.8125

14.13+9.8215=23.9425

from A to C displacement increases with time such that the slope of the x-t graph is positive

from C to D it is almost zero; from D to F it is negative

Also, slope of x-t graph is velocity

Thus, the positive velocity is seen in A to C

To find f(2), it means to find the value of y when x = 2.

From the graph, when x = 2, the corresponding y-coordinate = 0.

Therefore,

Answer:

The simple interest that said investment yielded was 3.75% per year.

Step-by-step explanation:

Given that Sarah's current account balance is $ 2,600, and she made a single lump sum amount of $ 2,000 eight years ago into the account, to calculate the equivalent simple interest rate (quoted annually) that she earned the following calculation must be performed:

(2,600 - 2,000) / 8 = X

600/8 = X

75 = X

2,000 = 100

75 = X

75 x 100 / 2,000 = X

7,500 / 2,000 = X

3.75 = X

Thus, the simple interest that said investment yielded was 3.75% per year.

Answer:

C) 273 ft²

Step-by-step explanation:

Answer:

after 42 mm the next one is 63mm and after 198mm it is 946mm

Step-by-step explanation:

The Diameter of the second circle is 63 mm and the circumference of the third circle is 946.

The circumference of a circle is the distance along a line across it. In other words, the length of a straight line created by opening a circle matches the radius of the circle. The formula to calculate circumference is C = π * Diameter.

Given that circumference of the first circle is 198mm by that we can drive the value of the diameter(D₂). from the formula of the circumference

C =  π D₂

198 = 3.14 * D₂

D₂ = 63mm.

Given that the Diameter of the first circle is 198mm by that we can drive the value of the circumference. from the formula of the circumference

C₃ =  π D₃

C₃ = 3.14 * 301

C₃ = 946 mm.

Therefore, the missing dimensions of the circular object are D₂ is 63mm and C₃ is 946mm.
