What is the area of this trapezoid?

Oksi-84 [34.3K]

Answer:

The answer is option b 130cm²

Area of a trapezium is 1/2(a + b) × h

where 'a' and 'b' are the parallel sides of the trapezium

h is the height

From the picture above

h is 10cm

'a' and 'b' are 17cm and 9 cm respectively

Area of the trapezium = 1/2 ( 17+9)× 10

= 1/2× 26 × 10

= 13 × 10

= 130cm²

Hope this helps

Find the area of the shaded region. Express your answer in terms of π.

rusak2 [61]

Answer:

335.115

Step-by-step explanation:

First you find the area of the circles to do that you do pi times radius squared

For the top square do 3.14(pi)time 3²=28.26

For the middle square do 3.14 times 4.5²=63.585

For the bottom square do 3.14 times 6²=113.04

Now find the area of the entire thing do 18×12+9+6+3=18×30=540

Finally do 540-the area of the squares 28.26-63.585-113.04= 335.115

So the shaded region is 335.115

Hope this helps and have a great day!

anyanavicka [17]

This is a combination problem.

The formula is n! / (r!(n-r)!

where n is the total number of people and r is the number of people to be picked.

n = 15, r = 4

15! / (4!(15-4)!)

15! / (4!*11!)

Total combinations = 1,365

A baseball cost $7 and a baseball bat cost $27. With a 6.5% tax rate, what is the total cost of buying both items?

mestny [16]

Answer:

Total cost of buying both items is $36.21.

Step-by-step explanation:

We are given that a baseball cost $7 and a baseball bat cost $27.

Also, we are given a tax rate of 6.5%

Now, to find the total cost of both items we will find the individual costs of both items by applying tax rate on it.

Cost of baseball after applying tax rate is given by;

Since we know that by applying a tax on any item it's cost gets increased.

So, Cost of baseball after tax = Cost of baseball before tax + Amount of tax

Amount of tax = Tax rate $\times$ Cost of baseball

= 6.5% $\times$ $7

= $\frac{6.5}{100} \times 7$ = $0.455

So, Cost of baseball after tax = $7 + $0.455 = $7.455

Cost of baseball bat after applying tax rate is given by;

Cost of baseball bat after tax = Cost of baseball bat before tax + Amount of tax

Amount of tax = Tax rate $\times$ Cost of baseball bat

= 6.5% $\times$ $27

= $\frac{6.5}{100} \times 27$ = $1.755

So, Cost of baseball bat after tax = $27 + $1.755 = $28.755

Now, the total cost of buying both items = Cost of baseball after tax + Cost of baseball bat after tax

= $7.455 + $28.755 = $36.21

Therefore, the total cost of buying both items is $36.21.
