A valuable collection of coins contained old nickels, dimes,quaters, and pennies. The face value of the pennies was $8. Therewere seven more than three times as many quaters as dimes andsixteen less than twice as many nickels as quaters. If the facevalue of the entire collection was $38.40, how many of each kind ofcoin was there?

[tex] \sf \: -15 < x - 8 < -4 [/tex]

[tex]\sf \longmapsto−15+8<x−8+8<−4+8[/tex]

[tex]\sf \longmapsto−7<x<4[/tex]

[tex] \boxed{\sf−7<x<4 }[/tex]

Answer:

A

Step-by-step explanation:

the leading degree(the biggest power in the function) x^4 and the leading coefficient is the number next to the highest power which is -5

so the answer should be

-5,4,x -> infinity, f(x) -> -infinity ; x -> -infinity, f(x) -> -infinity    

when you get asked questions like this look for the biggest power and the number next to it. if the power is even x will always be positive if its odd x can be either positive or negative it depends on restrictions.

for instance in this example -5 * x^4 will always give you negative because -5 will multiply with a positive number x (the power is even so its always positive)

Answer:

k ≥ 13/5 or k ≥ 2.6 ( same thing )

Step-by-step explanation:

symbol stays the same throughout (≥)

subtract 6 from both sides of the symbol ( 13 ≥ 5k)

divide both sides by 5 (13/5  ≥ k )

your answer can be written as k ≥ 13/5 or k ≥ 2.6

Answer:

A fraction is essentially division, so 3/5 is the same as 3 ÷ 5

3÷5 = 0.6

[tex]5\sqrt{3\\[/tex]

(imagine the square root is the divsion thing)

5 cannot go into 3 so the answer is a decimal

then add a zero at the end of 3 to make 30

   0.

[tex]5\sqrt{30[/tex]

and 5 can go into 30, 6 times so you add a 6 to make 0.6

    0.6

Answer:

The answer is 100.

Step-by-step explanation:

I started with solving 4 divided by 5. It was 0.8. I then started going thru 1 to 10 to 20 to 50 to 100. I was comparing big numbers. I then realized 100+0.8 times 100 = 180!

Answer: [tex]x=100[/tex]

If the equation is [tex]x+\frac45 x = 180[/tex] we add on the LHS: [tex]x(1+\frac45) = 180 \rightarrow x(\frac55+\frac45)= 180\\\frac95 x = 180[/tex]

At this point we divide both sides by 9 and multiply by 5:

[tex]x=\frac 59 (180) = \frac59 (2\times 9 \times 10) = 100[/tex]

Answer:

820 centimeter :3

Step-by-step explanation:

8.2 meters

move the decimal back twice because of KiloHecaDecaBase (m,l,g)DeciCentiMilli

As we know 1 meter is equal to 100 centimeters so the height of the tree 8.2 meters is equal to 820 meters

The same attribute is expressed using a unit conversion but in a different unit of measurement.

For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.

Measurements are frequently offered in one set of units, like feet, but are required in another set, like chains.

A conversion factor is a mathematical equation that facilitates an equal exchange of feet for chains.

Given, The height of a tree is 8.2 meters, now we know 1 meter is equal to 100cm so to convert some quantity from meters to centimeters we multiply by 100.

∴ 8.2 meters is equal to (8.2×100) = 820 centimeters.
