Answer:

Look below

Step-by-step explanation:

(a) The area of a triangle is:

$A=\frac{1}{2}bh$

The height of this triangle is h and it's base is 4+h so...

$A=\frac{1}{2}*[h*(h+4)]$

$A=\frac{1}{2}*(h^2+4h)\\A=\frac{h^2}{2}+2h$

(b) If the height is 8 cm, then the base is 4+8 which is 12 cm so...

$A=\frac{1}{2}*8*12=4*12=48 \ cm^2$

How do you solve -7-x=24

Airida [17]

Answer:

-31

Step-by-step explanation:

you have to get the variable on one side alone. so you would add the -7 to the 24 then divide by -1 because you have a -x when adding the -7 to the 24

two wheels are rolled simultaneously. The radius of the smaller wheel is r feet and the radius of the larger wheel 2r feet. If b

Nuetrik [128]

The circumference of a circle is C=2πR, where R is the radius of the circle and π≈3.14.

So if we open the circumference of the circle into a straight line segment, the length of this segment is C=2πR≈2*3.14*R=6.28R

4 rotations mean 4 circumferences that is 4 segments of length 6.28R,
which makes a linear distance of 4*6.28R=25.12R

i: the radius of the smaller wheel is R=r, thus it covers a distance of 25.12r feet

ii: the radius of the smaller wheel is R=2r, thus it covers a distance of 25.12*2r=50.24r (feet)

50.24r is twice 25.12r, thus the larger wheel traveled Twice the distance of the smaller one.

Answer: the larger covered twice the distance of the smaller.

How might this number be shown on a calculator?<br> 5.31x1037 (37 is above 10)<br> [?]e[ ]

Arisa [49]

Answer:

$5.31E37$

Step-by-step explanation:

Given

$5.31 * 10^{37}$

Required

How it'd be displayed on a calculator

Standard calculators, today are built to always convert huge numbers or extremely small number to scientific notations;

This was done to allow the calculator fit each values on its screen

$5.31 * 10^{37}$ is such a big number that it'll require the calculator to display it using scientific notations;

So, basically we have to convert $5.31 * 10^{37}$ to scientific notaton;

This is achieved by replacing $*10^{37}$ with $E37$

So, $5.31 * 10^{37}$ is equivalent to $5.31E37$

Pls help meeee!!! I have benchmarks monday

quester [9]

Answer:

therefore the correct options are:

B. the equation is an exponential decay equation.

F. $28000 represents the initial cost of an automobile that depreciates 27% per year over the course of t years.

Step-by-step explanation:

i) the cost of an automobile is given by the equation is

C(t) = $28000\times(0.73)^{t}$ , where C(t) represents the cost and t represents the time in years

ii) the above equation is an exponential decay equation. It is a decay equation because growth rate is 0.73 which is less than 1 and greater than zero.

ii) when t = 0 then the cost is C(0) = 28000 represents the initial cost.

iii) from the equation in i) we can understand that the cost depreciates 27% per year over the course of t years.

therefore the correct options are:

B. the equation is an exponential decay equation.

F. $28000 represents the initial cost of an automobile that depreciates 27% per year over the course of t years.

Using the following production tally, determine how many total mousetraps were produced during a shift: Quantity per package: 60

timofeeve [1]

The total number of packages completed was 41 and with 60 moustraps per package so 41 x 60 = 2460. Of these, 52 traps were from the previous shift and 34 were rejects so 2460-52-34 = 2374 produced + 24 in the last unsealed package = 2374 +24 = 2398.
