7

a trapezoid

equation for area = h(a +b) ÷ 2

so you sub that in

8(9 +21) ÷ 2 = 8 × 30 ÷ 2 = 120

so the area is 120cm

8

A trapezoid

equation for area = h(a +b) ÷ 2

so you sub that in

6(9 + 5 ) ÷ 2 = 6 × 14 ÷ 2 = 42

So the answer is 42 inches

9

A kite

equation for area = p× q ÷ 2

so you sub that in

(3+3)×(4.5+6.5) ÷ 2 = 6×11÷2 = 3

So the answer is 33 cm

sorry I can't see 10s measurements

Does anyone know how to do these?
ale4655 [162]

Answer:

D.

Step-by-step explanation:

f(x) = \sqrt[3]{4x}

g(x) = 2x + 3

\frac{f}{g} (x)  = 'f' divided by 'g'

\frac{\sqrt[3]{4x} }{2x+3}    Substitute.

x cannot be -\frac{3}{2} because that would create a zero in the denominator.

That's a no-no.

It makes it 'undefined'

I don't understand how to do find x and y, please help? thank yous.

#8) There are THREE right-angle (90°) TRIANGLES.

The "big" triangle has legs "x" and "no designation - <em>so lets call it Z" </em>and hypotenuse "4+5"<em> = 9</em>

The "left" triangle has legs "4" and "y" and hypotenuse "x"

The "right" triangle has legs "5" and "y" and hypotenuse "no designation - <em>which we named Z</em>"

Now, you can create a system of equations - you have three unknown variables and can create an equation for each triangle using the Pythagorean Theorem.

Big: x² + Z² = 9² → x² + Z² = 81

Left: 4² + y² = x² → 16 + y² = x² → 16 = x² - y² → x² - y² = 16

Right: 5² + y² = Z² → 25 + y² = Z²

Next, let's eliminate Z by using substitution....use the Right equation to plug Z² into the Big equation to create a NEW Big equation.

NEW Big: x² + (25 + y² ) = 81 → x² + y² = 81 - 25 → x² + y² = 56

Now, we have two unknown variables (x and y) and two equations (NEW Big and Left). Solve the system using any method. <em>I am going to solve using the elimination method)</em>

NEW Big: x² + y² = 56

+ Left: <u>x² - y² = 16</u>

2x² = 72 <em>added the NEW Big and Left equations</em>

x² = 36 <em>divided both sides by 2</em>

x = 6 <em>took square root of both sides (NOTE: -6 is disregarded because we are solving for a length, which cannot be negative) </em>

The last step is to plug the "x" value (<em>that we just solved for)</em> into one of the equations to solve for "y". <em>I am choosing to use the Left equation.</em>

<em> </em>x² - y² = 16

36 - y² = 16<em> </em>

- y² = 16 - 36

- y² = -20

y² = 20

y = √20

y = 2√5

Answer: x = 6, y = 2√5

Try #9 on your own and then check your answers below:

Big: Z² + x² = 12², Left: 3² + y² = Z², Right: y² + 9² = x²

Answer: x = 6√3, y = 3√3

Because you are working a late shift, you will get an increase in your wage. You will get and additional 10% per hour from 6:00p
siniylev [52]

CHECK THE COMPLETE QUESTION BELOW:

Supervisor: "Because you are working a late shift, you will get an increase in your wage. You will get an additional 10% per hour from 6:00 PM to 12:00 AM and additional 15% from 12:00 AM to 1:00 AM." Employee: "I am working from 2:00 PM to 12:00 AM. Between 2:00 PM and 6:00 PM, I will make $12.00 per hour. Between 6:00 PM and 12:00 AM, I will make __________ per hour

Answer:

I will make $13.2 per hour

Explanation:

It can be deducted from the question that that the money Employee gets money for Working from 2.00 PM to 6.00 PM = $12per hour

Also the Employee gets additional 10% of money for working from 6.00 PM to 12.00 AM which implies that

10% = (10/100)*$12per hour

=$1.2per hour

Again, Employee gets additional 15% of the money for working from 12.00 AM to 01.00 AM which can be calculated as:

15% = (15/100)*$12per hour

=$1.8 per hour

which means that Employee gets additional $1.8 per hour

of the money for working from 12.00 AM to 01.00 AM

Therefore, if Employee works from 2.00 PM to 12.00 AM,

Employee will gets money for Working from 2.00 PM to 6.00 PM as well as the 10\% extra wage which

= $12 + $1.2 = $13.2

= \$ 12 + \$ 1.2 = \$ 13.2
