Answer 1

Answer:

2.5z^2+3z+4.2

Step-by-step explanation:

Answer 2
i’m not quite sure what the question is but i’m guessing you need to simplify, if not lemme know and i’ll try help.

first combine the squared terms which is 1.5z^2+z^2= 2.5z^2

second combine the z terms
6z-3z=3z

then combine the numerical terms
4.5-0.3=4.2

so simplified that equation is
2.5z^2 + 3z + 4.2

Find the volume of the sphere with a radius, r, of 3/2 feet and π ≈ 3.14.

The volume formula for a sphere is:

V = 4/3 πr3

Enter you answer in the box provided, rounded to the nearest hundredth.
Thanks for your assistance ( :

Answers

Answer:

V= 14.13

Step-by-step explanation:

Information needed:

V= 4/3[tex]\pi[/tex]r^3

[tex]\pi[/tex]= 3.14

r= 3/2

Solve:

V= 4/3[tex]\pi[/tex]r^3

V= 4/3(3.14)(3/2)^3

V= 4/3(3.14)(27/8)

V= 14.13

V = 14.13

On a coordinate plane, a line goes through points (0, 0) and (5, 8.5). A triangle is formed with the line and the y-axis.
Use these similar triangles on the coordinate plane to determine the equation of a straight line with a slope of 5/3 that passes through the origin.
y = five-thirds x
y = three-fifths x
y = 3x + 5
y = 5x + 3

Answers

Step-by-step explanation:

It will be Y=5/3 x, Because if you put the points in Desmos then put Y=5/3 x then the line will pass through the points.

Y= 5/3 is correct that is your answer

A store has a 25% off sale on coats. With this discount, the price of one coat is$ 34.50. What is the original price of the coat?

Answers

Answer:

I believe this would make the original price of the coat $46.00

Step-by-step explanation:

Answer:

$46.

Step-by-step explanation:

set up as a proportion. when an item is reduced by 25%, that means you're paying 75% for it. so the proportion would be: 75/100=34.50/x. Once you solve for X, your answer will be $46.

Hope this helps!!!

SMART PPL PLEASE HELP!!! (explain your reasoning for bainliest)

Answers

Answer:

1. False

2. True

Step-by-step explanation:

If you work out the math for both you'll see that 45/100*72=32.4 and 45/72*100=62.5. Without doing the math; 45/100 is going to give you a different value than 45/72. Multiplying 100 by 45/72 is just going to add another place at the end and not change the actual value. For the second one, you are trying to figure out what part of 250 is 16% and vise versa. This means that the chunks the include that % are going to be equal. You aren't changing values, just finding chunks.

I hope this helps! Sorry if it doesn't make sense.

hi !

1.) False

take the first equation (45/100 x 72) and reduce it using the Least Common Denominator method to 9/20 x 72 to get 32 2/5. Using the same method, reduce the second equation to 5/8 (divide both the numerator and denominator to get 9) and multiply it by the LCD, 100, which would equal 62 1/2. now you have two different fractions, 32 2/5 and 62 1/2. you can either cross multiply the bigger numbers or you can reduce the equations to 9/5 x 18 and 5/2 x 25. Either way, if you cross multiply you will get your answer, false.

2.) True

Percents need to be multiplied by 0.01 (one-one hundredth.) multiply 16 by 0.01 and you get 0.16. Then you just multiply 0.16 by 250 and get 40. Now, to get the other percentage you would also multiply 250 by 0.01 and get 2.5. like earlier, you multiply the decimal, 2.5, to the other number, 16, and you get 40.

hope this helps :]

Which equation describes the statement shown?

The output is one more than twice the input.

Group of answer choices

y = x + 2

y = 2x + 1

y = 2x + 3

y = 2x - 1

Answers

y=2x+1
x is the input, so the 2x will make it twice the input, and the +1 will make it one more, therefore y(the output) is one more than twice the input :)
