A business was valued at £80000 at the start of 2013. In 5 years the value of this business raised to £95000. this is equivalent
dedylja [7]

Answer:

20%

Step-by-step explanation:

Value increased in 5 years =  £95000 -  £80000 = £5000

Value increase in 1 year  =5000/5 = 1000

Increase % = (1000/5000 ) * 100  = (1/5) *100 = 20%

If the circumference of the circle is 37.68 units, what is the area? (Use 3.14 for pi .)
solniwko [45]

Answer: 113.04

Step-by-step explanation: The equation for the area of a circle is pi r squared so you have to find the radius first. To find the radius, find the diameter first. A way to do this which was easiest for me was dividing 37.68 by pi (3.14), which is 12. Divide the diameter by 2 to find the radius, 6.

Now use the equation from the beginning, pi r squared. So plug in pi as 3.14, then the radius as 6. It is important to always square the radius first, which would be 36. Now multiply 36 by 3.14, and there should be your answer.

What is the value of x + 3y + z if x = 4, y = 5, and z= 22<br>a) 16<br>b) 41<br>c) 2​
fgiga [73]

Answer:

OPTION B - 41

Step-by-step explanation:

An expression is given and the corresponding values for the expression are also given. We have to substitute the given values to arrive at the answer.

The given expression is:   x + 3y + z.

Also given: x = 4, y = 5, z = 22.

Substitute these values in the above expression, we get:

4 + 3(5) + 22 = 4 + 15 + 22 = 41.

∴                                       x + 3y + z = 41
