need to know how to do this problem.

2^2+3*(6_3)^2

Answer:

The answer would be 2133.3cm squared

Answer:

9r^4

Step-by-step explanation:

first step would be to use the exponent rule.

(12r^2t^2)^2/(4t^2)^2

once you have done this, you are able to completely simplify

144r^4 t^4/16t^4   =  9r^4

btw, could you please give me brainiest

Answer:

A: Negative cash flow, $50

Step-by-step explanation:

Bob makes $3000 a month.

Every month he has to pay $950:

3000 - 950 = 2050

Pay an additional $250:

2050 - 250 = 1800

And another additional $1850:

1800 - 1850 = -50

Therefore, he has a negative cash flow of $50 a month.

Answer:

=12

Answer:

A

Step-by-step explanation:

Let T represent the total number of turtle nests found during the season.

The 28 turtle nests was 40% of 0.4 of the total. Therefore:

[tex]28=0.4T[/tex]

So, to find T, divide both sides by 0.4:

[tex]T=70[/tex]

So, the total number of turtle nests the group found during tthe season was 70.

Hence, our answer is A.

Step-by-step explanation:

Answer:

An equation for the parabola would be y²=-19x.

Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis.  This means we will use the standard form

(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.

Beginning with the directrix:

x=h-p=4.75

h-p=4.75

Since the vertex is at (0, 0), this means h=0 and k=0:

0-p=4.75

-p=4.75

p=-4.75

Substituting this into the standard form as well as our values for h and k we have:

(y-0)²=4(-4.75)(x-0)

y²=-19x

Answer:

Multiplying 10 by t will not work under most circumstances so it would be 10t which means 10*t but if you substitute the t for lets say 4 then you would get 40 but that wasn’t the question so your answer is 10t

Answer:

What is the average time it took the car to travel 0.25 meters?

What is the average time it took the car to travel 0.50 meters?

I hope is work you!!

(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.

(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.

Velocity is the rate of change of displacement with time. The velocity of the  cars depends on displacement and time of motion.

The first velocity is calculated as follows;

v1 = 0.25 m / t1

let t₁ = 2 s

v₁ = 0.25/2

v₁ = 0.125 m/s

v2 = 0.25 m / (t2 – t1)

let t₂ = 3 s

v₂ = 0.25(3 - 2)

v₂ = 0.25 m/s

The complete question is below:

Calculate the first and second velocities of the car with two washers attached to the pulley, using the formulas

v1 = 0.25 m / t1, and

v2 = 0.25 m / (t2 – t1)

Answer:

x is 84.

Step-by-step explanation:

this is because 84 divided by 18 equals 4.6

hope this helped :D

Answer:

if you're looking for the value of x: a number x/18=4.6 x=82.8

Step-by-step explanation:

it's a one step equation: x is being divided by 18 to get 4.6, so to get x by itself, multiply by 18 on the left side because (x/18) * 18 = x, but what you do to one side you have to do to the other, so then multiply 4.6 by 18 also to get x=82.8.

Step-by-step explanation:

To calculate the percentage of underclassmen interested in taking a Mandarin course next year, find the marginal frequency for the total number of underclassmen who showed interest in Mandarin. There are 145 underclassmen who showed interest in Mandarin courses.

Find the total number of underclassmen who were polled. This number is located at the intersection of the marginal frequency row and marginal frequency column. There are 620 underclassmen who were polled in the survey.

Calculate the approximate percentage of underclassmen interested in taking a Mandarin course next year.

Answer:

40000 and 12.5% respectively

Step-by-step explanation:

soln:

given,

cost price(c.p)=320000

selling price(s.p)=280000

loss(l),loss percentage(l%)=?

we know,

l=c.p-s.p

or,l=320000-280000

•°•l=40000

now,

l%=l/c.p*100%

or,l%=40000/320000*100%

•°•l%=12.5%
