the sales price?

Answer:

A. y = 2x^2 - 1

Step-by-step explanation:

Try the points of x and y by substitution

This gives us the function:

y = 2x^2 - 1

Answer:

What happens to an exoskeleton when an arthropod grows? The exoskeleton does not grow or expand, so it is shed and a new larger one grows. This is called molting. ... The process of shedding an outgrown exoskeleton.

Step-by-step explanation:

Answer:

As the body underneath the exoskeleton grows, the animal begins to outgrow its tough exterior. In order to cope with this situation, arthropods undergo a process of shedding their exoskeleton and forming a new one periodically throughout their lifetime. A crab undergoing the process of ecdysis, or molting.

Step-by-step explanation:

Having a job that pays at $7 per hour is quite nice. And the question says that if he does overtime, he gets 1 and a half times the normal price of $7. This means that, for every overtime he works, he will get paid at

7 * 1.5 = $10.5

The question didn't state what, but if it's anything to go by the wages expected to be paid then I'd say the job isn't worth it if it's overly stressful. I said so because most jobs out there aren't really about the workers, but the money instead.

Answer:

the sand and cement needed is 7.5 kg and 4.5 kg respectively

Step-by-step explanation:

The computation of the sand and cement needed is shown below:

Given that

The mix of sand and cement is 5kg and 3kg i.e. its ratio is 5:3

And there is a 12kg of mix of both things

So individually it required

For sand = 12 × 5 ÷ 8

= 7.5 kg

For cement = 12 × 3 ÷ 8

= 4.5 kg

Hence, the sand and cement needed is 7.5 kg and 4.5 kg respectively

Answer:

x = − 3

Step-by-step explanation:

Let's solve your equation step-by-step.

− 2x − 4 = x + 5

Step 1: Subtract x from both sides.

− 2x − 4 − x = x + 5 − x

− 3x − 4 = 5

Step 2: Add 4 to both sides.

− 3x − 4 + 4 = 5 + 4

−3x = 9

Step 3: Divide both sides by -3.

−3x  / −3  =  9  / −3

x = − 3

Answer:

6^4(6^-5)

If base is equal at multiplication we add index.

ex: a^(x)

a = base

x=power = index

6^4 .(6^-5)

6^(4+(-5)

6^(4 - 5)

6^(-1)

Answer:

She can type 650 words in 10 minutes.

Step-by-step explanation:

390 divided by 6 is 65. Anita types 65 words per min. 65 times 10 is 650. Therefore she types 650 words in 10 mins.

Answer:

650 words

Step-by-step explanation:

So you divide 390 by 6 so that you can figure out how many words she types per minute.

390/6= 65

So she types 65 words per minute,

Then you multiply 65 by 10 because thats how many minutes your trying to figure out.

65*10= 650

Answer: 5 5/6

Step-by-step explanation:

To divide fractions, use KCF (keep change flip)

2 1/3 = 7/3

the reciprocal of 2/5 is 5/2, so

7/3 x 5/2 = 35/6 = 5 5/6

Answer:

Step-by-step explanation:

so you understand what to do, or what they want you to figure out.

AD  is an "arc length" .  So they want to know the length, in degrees. along the circle , from A to D.   Why didn't they just say so, huh.  :D   well, they kinda did, but not as clear as they could have.

next.  you need to know how far around a circle is all the way around?  

if you guessed 360°,  you are right

next because they gave us that angle of 93° we know all the angles around the point E,  complimentary angles add to 180 so 180-93 = 87°.  That's the to the left of 93 and directly below it too.  This is the answer to the 2nd question  ∠DEC= 87°

we can only write arc length of AD in respect to what we know about the circle.

so,   arc length of AD is  161° + BA + AD + DC = 360

or getting AD by it self , then

AD =360 -161 -BA -DC

AD = 199°-BA-DC

maybe that's all you need to do,  also i'm wondering if there is some more info about this problem , maybe at the top of the page?  of off the screen?

Answer:

Step-by-step explanation:

33 1/3%=100/3%

A percent as a decimal is percentage divided by 100

(100/3)/100=1/3

Since 1/3 of a number is 24 we can say

n/3=24

n=72

So 24 is 33 1/3% of 72
