Answer:

405,376

Step-by-step explanation:

the question is worded weirdly.

Its saying 37,700 copies were sold in one month and then that amount is 9.3% of books sold to date. So, its saying that 37,700 is only 9.3% out of 100%. To get the hundred i devided 37,700 into 9.3 to see how much 1% is. then i multiplied that by 100

show how to solve the problem 378 ×6 using place value with regrouping. explain how you knew when to regroup

liraira [26]

You should regroup when the product of the two numbers are greatre than nine so 378*6 6*8 is 48 so you would the 8 and regroup the 4 and do the same thing for the rest of the numbers if the product is greater than nine. Your answer will be 2268.

Find the coordinates of the point

alina1380 [7]

Answer:

$(x,y) = (\frac{-10}{13},3)$

Step-by-step explanation:

Question is not well formatted; However, the given parameters are

Given

Point = 3/10

A = (-4,-6)

B = (10,7)

Required

Determine the coordinates of the point

Represent the point as ratio

$Point = 3:10$

The coordinates can be solved using

$(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})$

Where

$m:n = 3:10$

$(x_1,y_1) = (-4,-6)$

$(x_2,y_2) = (10,7)$

Substitute these values in the above formula:

$(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})$

$(x,y) = (\frac{3 * 10 + 10 * -4}{3+10},\frac{3 * 7 + 10 * -6}{10+3})$

$(x,y) = (\frac{30 -40}{13},\frac{21 -60}{13})$

$(x,y) = (\frac{-10}{13},\frac{-39}{13})$

$(x,y) = (\frac{-10}{13},3)$

Hence;

The coordinates of the point is $(x,y) = (\frac{-10}{13},3)$

Using technology, determine the quarterly payment on a 4 year loan of $16,231 at 5.1% compounded quarterly. round your answer to

Vesna [10]

The quarterly payment will be $1,127.86

<h3>What is compound interest?</h3>

Compound interest is the interest on a loan or deposit that levied on both the first principal and the collected interest from past periods.

The amortization formula is ...

$A=\dfrac{P\timesr}{(1-(1+r)^{-n}}$

where A is the payment amount, P is the principal amount, r is the interest rate per period, and n is the number of periods.

Here, we have

P=$16,231, r=0.051/4=0.01275, n=4·4=16.

So, the payment is ...

$A=\dfrac{16231\times 0.01275}{1-(1.01275)^{-16}}$

$A=$1127.86$

Hence the quarterly payment amount is $1,127.86.

The function shown models the depth d (in inches) of snow on the ground during the first 9 hours of a snowstorm, where t is the

kondaur [170]

Complete Question:

The function shown models the depth d (in inches) of snow on the ground during the first 9 hours of a snowstorm, where t is the time (in hours) after the snowstorm begins.

The -intercept means that there were[ ]inch(es) of snow on the ground at the start of the storm and the slope means that[ ]inch(es) of snow falls every hour during the storm.

Function: d(t)= 1/2t+6

Answer:

$b = 6$

$m = \frac{1}{2}$

Step-by-step explanation:

Given

$d(t)= \frac{1}{2}t+6$

Required

Determine the y intercept and the slope

y-intercept:

$d(t)= \frac{1}{2}t+6$

A function has a format of:

$d(t) = mt + b$

Where b represent the y intercept:

By comparison of $d(t) = mt + b$ and $d(t)= \frac{1}{2}t+6$

$b = 6$

Slope:

A function has a format of:

$d(t) = mt + b$

Where m represent the slope

By comparison of $d(t) = mt + b$ and $d(t)= \frac{1}{2}t+6$

$m = \frac{1}{2}$
