Answer:
She would have to spend $168
Step-by-step explanation:
Step one:
Divide 28 by 8 to find out how much one individual notebook costs.
28/8 = $3.50
$3.50(a)
a = amount of notebooks bought
Now multiply it by how many she buys
$3.50(48) = $168
This means she spend $168 on 48 notebooks.
place the digits 4, 5, 6, 7, and 8 in the boxes below to make the largest and smallest sums possible
Smallest: 9
Largest: 30
In order to get the largest possible sum using the digits 4, 5, 6, 7, and 8, you should order the digits from largest to smallest (87654). For the smallest possible sum, you should order the digits from smallest to largest (45678).
Explanation:Here's how you can arrange the digits 4, 5, 6, 7, and 8 to get the largest and smallest possible sums. If you're aiming for the largest sum, you should place the largest digit in the hundreds place, the next largest in the tens place, and so on. That means that you'd arrange the digits as 87654.
For the smallest sum, you should do exactly the opposite, placing the smallest digit in the hundreds place. That would result in 45678. Therefore, the largest possible sum of these digits is 87654 and the smallest possible sum is 45678.

What would be the result of (-9+6i)(3-2i) ?
To find the result, you need to multiply the two binomials (the picture shows how to multiply them).
( -9 + 6i )( 3 - 2i )
= -27 + 18i + 18i - [tex]12i^{2}[/tex]
Combine like terms.

Answer :-
The answer is '-8'.
Step-by-step explanation :-
Given equation :
... [tex]10p + 5 = \frac{18p-6}{2}[/tex]
Multiplying '2' on both sides :-
... [tex]2(10p + 5 ) = 2 (\frac{18p-6}{2})[/tex]
... [tex]20p + 10 = 18p - 6[/tex]
Subtracting 18p on both sides -
... [tex]2p + 10 = -6[/tex]
Subtracting 10 on both sides :-
... [tex]2p = -16[/tex]
Dividing by 2 on both sides :-
... [tex]p=\frac{-16}{2}[/tex]
... [tex]p = -8[/tex]

−3r+10=15r−8 solve for R
Answer,
R = 1
Explanation,
Subtract 10 from both sides,
-3r + 10 - 10 = 15r - 8 - 10
Simplify,
-3r = 15r - 18
Subtract 15r from both sides,
-3r - 10 = 15r - 18 - 15r
Simplify,
-18r = -18
Divide both sides by -18,
-18r/-18 = -18/-18
Simplify,
R = 1
Hope this helps :-)
To solve the equation −3r+10=15r−8 for r, we first move all r terms to one side and constant terms to the other to get -18r = -18. We then divide both sides by -18 to find that r = 1.
Explanation:The question is asking us to solve the equation −3r+10=15r−8 for the variable r. To do this, we first combine all terms involving r on one side of the equation and constant terms on the other side. Therefore, the equation becomes:
−3r - 15r = -8 - 10
which simplifies to:
-18r = -18.
We then divide both sides of the equation by -18 to solve for r:
r = 1.

What is the slope of the line that contains the points (4,8) and (9,8)? What type of line is it?
A. Slope = 0; horizontal line
B. The line has no slope; it's a vertical line.
C. Slope = 0; vertical line
D. The line has no slope; it's a horizontal line.
For this case we have the following:
Given points: [tex](x1, y1) = (4,8)[/tex] and [tex](x2, y2) = (9,8)\\[/tex]
The formula of the slope is given by:
[tex]m = \frac{(y2-y1)}{(x2-x1)}\\\\m = \frac{(8-8)}{(9-4)}\\\\m = \frac{0}{5}\\\\m = 0\\[/tex]
So, the slope is [tex]m = 0[/tex]and the line is a horizontal line
Answer:
Slope 0, horizontal line
A model airplane flies 18 feet in 2 seconds. What is the airplanes speed in miles per hour?
Answer:
6.1 miles per hour
Step-by-step explanation:
That is 9 feet per second.
There are 3600 seconds in an hour.
9 x 3600 is 32400
That is 32400 feet in an hour.
32400 feet is about 6.1 miles. (rounded)
The airplanes speed is 6.1 miles per hour.
The speed of the airplane will be 6.13 miles/hour. It is obtained by the unit conversion.
What is speed ?Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. its si unit is m/sec.
Unit conversion;
1 ft/sec=0.681818 miles/hr
The speed in ft /sec;
v=d/t
v=18 feet/2 second
v=9 ft/sec
1 ft/sec=0.681818 miles/hr
9 ft/sec=9×0.681818 miles/hr
9 ft/sec=6.13 miles/hr
Hence, the speed of the airplane will be 6.13 miles/hour.

y=−2x+4
Complete the missing value in the solution to the equation.
(____,-2)
(3, - 2)
given y = - 2, then
- 2x + 4 = - 2 ( solve for x )
subtract 4 from both sides
- 2x = - 6 ( divide both sides by - 2 )
x = [tex]\frac{-6}{-2}[/tex] = 3
The coordinate that completes the solution to the equation is (3, -2)
Given the function y = -2x + 4
We are to find the value of x if y is -2
Substitute y = -2 into the function as shown:
-2 = -2x + 4
Subtract 4 from both sides
-2 - 4 = -2x + 4 - 4
-6 = -2x
x = 6/2
x = 3
Hence the coordinate that completes the solution to the equation is (3, -2)

Ricardo would swim a farther distance in 1 hour. By taking the number of miles he swam and in the fraction of the hour, you can find the answer.
Divide 5 1/4 by 3 because it took 3/5 of an hour to swim that far. That would lead to 1 3/4 for 1/5 of an hour. Now that we know this, we can multiply 1 3/4 to 5 to get how much he would swim in 1 hour which is 8 3/4
Divide 4 1/2 by 5 because it took 5/9 of an hour to swim that far. That would lead to 9/10 for 1/9 of an hour. Now that we know this, we can multiply 9/10 to 9 to get how much he would swim in 1 hour which is 8 1/10
Since 8 1/10 is less than 8 3/4, Ricardo swam farther

Hey there!!
Given equation :
A + B + C = D
and solve for B
In order to solve for the B, we will need to take all the other variables to the other side.
... A + B + C = D
Subtracting A on both sides.
... B + C = D - A
Subtracting C on both sides.
... B = D - A - C
Hence, we got the value for B.

Gabby drove 124 miles in 150 minutes. Find Gabby's speed in kilometers per hour. (HELP FOR TEST TMRRW PLZ 15 POINTS!!!)
First, you need to convert the minutes into hours, to do this you divide the minutes by 60 (the amount of minutes in an hour). Once you've gotten the value (which is 2.5), you divide that by the amount of miles drove, then you get the unit rate, or in other words the kilometers per hour, which equals 49.6 km/h

sales tax on a $400 stereo is $16. What is the tax on a $650 TV?
The reason being is that we need to find it out of 100. So, we divide 400 by 4 and because we did that to the denominator we have to do it to the numerator so 16 divided by 4 is well 4. So we found out that is 4/100 we just divide that by 650 and we get 26.
TL;DR it’s $26
Tax is the price charged on an object. This shows that the tax on a $650 TV is $26
If the sales tax on a $400 stereo is $16, this can be written as:
$400 = $16
To get the sales tax on $650 TV, we can write;
$650 = x
x is the required tax;
Divide both expressions to have:
[tex]\frac{400}{650} =\frac{16}{x} \\400x = 16 \times 650\\400x = 10400\\x = \frac{10400}{400}\\x= \$26[/tex]
This shows that the tax on a $650 TV is $26

DEEPER A science teacher showed an image of a carpenter bee on a wall. The image is 10 times as large as the actual bee. Then he showed another image of the bee that is 10 times as large as the first image. What is the length of the bee in the second image?
Answer:
The length of the bee in the second image is 100 times the original.
Step-by-step explanation:
A science teacher showed an image of a carpenter bee on a wall. The image is 10 times as large as the actual bee.
Let the size of the actual bee be = x
So, the first image is = 10x
Then he showed another image of the bee that is 10 times as large as the first image.
Now as the length of the carpenter bee is not given, you can multiply the given length by 100 to get the answer.
The second image will be = [tex]10\times10x=100x[/tex]
So, the length of the bee in the second image is 100 times the original.
