A rucksack can hold a maximum of 3 kg.
A particular textbook has a mass of 650 g.
What is the maximum number of these textbooks that the rucksack can hold?
Reason:
x = number of textbooks
650x = weight of all x books, at 650 grams each
3 kg = 3000 g
650x = 3000
x = 3000/650
x = 4.615 approximately
Round down to the nearest integer. This is because 4 textbooks weigh 4*650 = 2600 grams = 2.6 kg; while 5 textbooks weigh 5*650 = 3250 grams = 3.25 kg which is over the weight limit.
This means 4 books is the most the rucksack can hold. This is of course only when we have 4 of the same exact book.

Aakesh has two bags of marbles. The first bag contains 6 red marbles, 4 blue
marbles, and 5 green marbles. The second bag contains 3 red marbles, 1 blue
marble, and 5 green marbles. Aakesh will randomly select one marble from
each bag.
What is the probability that Aakesh will select a green marble from each bag?
A. 4/9
B.1/3
C. 5/9
D. 5/27
The answer for the 1st bag is option B = 1/3
The answer for the 2nd bag is option C = 5/9
Number of marbles in 1st bag - 15 (6 red, 4 blue & 5 green)
Number of marbles in 2nd bag - 9 (3 red, 1 blue & 5 green)
The formula of probability = Total number of events in the outcome /total number of outcomes.
Now the probability that Aakesh will select a green marble from the 1st bag is 5(green marbles)/15(total number of marbles in 1st bag)
That is 5/15=1/3
Now the probability that Aakesh will select a green marble from the 2nd bag is 5(green marbles)/9(total number of marbles in 1st bag)
That is 5/9

☆☆●◉✿ Answer:✿◉●☆☆
C.) 5/9
☆☆●◉✿Step-by-step explanation:✿◉●☆☆
First we must figure out how many marbles we have in total.
Meaning we will add all of the marbles together in bag one and then bag two.
Bag one: 6+4+5= 15
Bag two: 3+1+5= 9
Total= 24 marbles
Now we will try and figure out how many greens are in the total amount of marbles.
Amount of green marbles in bag one: 5
Amount of green marbles in bag two: 5
Total green marbles: 10
The third and final step!
10/24 is the amount of green marbles so the answer is C!
Hope I helped~! >w<→⇒brainliest please? ∑(OΔO )♥♥︎3a: complete the table with values for x and y that makes this equation true 3x+y=15
3b: create a graph, plot these points, and find the slope of the line that goes through them.
Answer:
a. see the attachment for the table (also reproduced below)
b. slope = -3; see the attachment for a graph
Step-by-step explanation:
A table of values for the function can be filled a couple of ways. One way is to draw the graph of the equation, and read the point values from it. Another way is to solve for each of the variables, and use those equations to find the missing table values.
__
a.Solving the equation for y, we get ...
3x +y = 15
y = -3x +15 . . . . . . subtract 3x; this is "point-slope form"
For the purpose of evaluating for different values of x, we can rearrange this a bit to ...
y = 3(5 -x) . . . . factor out 3
The given table has x-values of 0, 2, 3, 6. The corresponding y-values are ...
y = 3(5 -{0, 2, 3, 6}) = 3{5, 3, 2, -1} = {15, 9, 6, -3} . . . . for x={0, 2, 3, 6}
Solving the equation for x, we get ...
y/3 = 5 -x . . . . . divide the above equation by 3
x = 5 -(y/3) . . . . . add x-(y/3)
For y-values {0, 3, 8}, the corresponding x-values are ...
x = 5 -{0, 3, 8}/3 = 5 -{0, 1, 8/3} = {5, 4, 7/3} . . . . for y={0, 3, 8}
Then our table of values is ...
[tex]\begin{array}{|c|c|c|c|c|c|c|c|}\cline{1-8}x&2&4&6&0&3&5&7/3\\y&9&3&-3&15&6&0&8\\\cline{1-8}\end{array}[/tex]
__
b.The points in the above table can be plotted, and the line drawn through them. Sometimes using the points that are farthest apart makes this easier: (0, 15) and (6, -3).
slope
When we solved for y, we had the equation in slope-intercept form. The slope is the x-coefficient in that equation:
y = -3x +15 ⇒ slope = -3
I’m studying for a test, could you help me with A, B, and C? (image below)
Answer:
a = 51
b = 51 (??not so sure)
c = 20 cents
Step-by-step explanation:
a) 25 x 408 = 10200
10200 ÷ 200 = 51 square ft is one one roll.
b) the surface area of an average gift is 51 sq ft (?)
c) 40 ÷ 200 = 0.2
each roll costs $40 dollars. each roll can wrap 200 gifts so 40 ÷ 200 = $0.20/ 20 cents
What is the least positive integer by which 24 should be divided so that the resulting integer is a perfect square?
24 = 2 × 2 × 2 × 3
In a perfect square, all the prime factors occur in pairs.
In 2 × 2 × 2 × 3, 2 occurs in a pair, and only one each of 2 and 3 remains unpaired.
So, the least positive integer by which 24 should be divided to get a perfect square = 2 × 3 = 6.

Tell whether the angles are complementary or supplementary. Then find the value of x.
help pls i don't get it...
Answer:
The angles are complementary, hence the answer is the second one.
Step-by-step explanation:
Since 90° - 65° = 25°, we know that 5x =25°, hence x is equal to 25° ÷ 5, which is 5°, hence, x = 5° and the answer is the second one
Hope this helps :))
P.s. can you mark me as the brainliest? <3
Answer:
(b) Complementary; x = 5
Step-by-step explanation:
Angles are complementary when the total of their measures is 90°. Angles are supplementary when the total of their measures is 180°. A right angle has a measure of 90°, so any pair of angles that has the same total measure as a right angle are complementary angles.
__
interpreting the figureThe little square in the corner of the figure indicates that angle is a right angle, and has a measure of 90°. The ray headed off to the northeast divides that 90° angle into two parts, labeled 65° and 5x°. In math, the whole is the sum of the parts, so the 90° angle is the sum of the 65° and 5x° angles.
Those two angles total 90°, so they are complementary.
making use of the relationNow that you understand the sum of the two marked angles is 90°, you can use that fact to write an equation:
65° +5x° = 90° . . . . equation relating the complementary angle measures
solutionThis is a 2-step linear equation, so is solved the way that kind of equation is solved.
5x° = 25° . . . . . step 1: add the opposite of 65° to get the x-term alone
x = 5 . . . . . . . . .step 2: divide by the coefficient of x to get x alone
The angles are complementary, and the value of x is 5.
_____
Additional comment
In order to keep the equation true, whatever operation we perform on one side of the equation must also be performed on the other side. When we say "add -65°", we mean that value is added to both sides of the equation. Above, we have skipped the steps of showing that addition and the subsequent simplification. (Similarly, we skipped the steps showing the division and the simplification process.)
65° +5x° = 90° . . the original equation. We want to eliminate the 65° term.
65° +(-65°) +5x° = 90° +(-65°) . . . . . add -65° (to both sides)
(65° -65°) +5x° = (90° -65°) . . . . . simplify the expressions a bit
0° +5x° = 25° . . . . . . . . . . . do the subtraction
5x° = 25° . . . . . . . . . . . 0 is the identity element for addition. Adding it changes nothing.

Por favor.
(Will give 25 points!) Solve the system of linear equations by substitution. 3x - 2y = 12 and 4x + 2y = 16
Let
Eq1 : x - 2y = 12
Eq2 : 4x + 2y = 16
For substitution, we need to rearrange on of the equations so that we can substitute it in the other. Let's pick eq2 and rewrite it as 2y = 16 - 4x. We see that eq1 also has 2y in it, so we can plug this new version of eq2 in there.
3x - (16-4x) = 12
Now solve for x.
7x=28, so x=4
Plug that into either equation to solve for y. You get y=0.
So your answer is x=4, y=0

Trey made a scale drawing of a microchip using s scale of 2 inches to 1 centimeter. His drawing was an enlargement that depicted the chip as 6inches long and 4 inches wide. However, the drawing isnt big enough to clearly show all of the chips components. So he wants to make the drawing bigger. Complete the steos below to figure the dimensions if trey changes the scale to 3 inches to 1 centimeter.
A) What is the actual length of the microship?
B) What is the actual width of the microchip?
C) Trey wants to change the scale of the drawing to 3in to 1cm. Use the actual length from part A to find the length of the microchip in treys new scale drawing.
D) Use the actual width from part B to find the width of the microchip in treys new scale drawing.
E) what is the ratio of a drawing measurement from the original scale to the corresponding drawing measurement in the new scale?
Answer:
A) The actual length of the microchip is 3 centimeters.
B) The actual width of the microchip is 2 centimeters
C) The ratio of the original scale drawing measurements to the new scale drawing measurements is 2 inches to 3 inches.
Step-by-step explanation:
A) actual length = scale length × reciprocal of scale factor
The scale is 2 inches to 1 centimeter, so the scale factor is. 2in/1cm The reciprocal of the scale factor is. 1cm/2in The length of the chip in the scale drawing is 6 inches.
= 6 in. x (1cm/2in)
= 3 cm
B) actual width = scale width × reciprocal of scale factor
= 4 in. x (1cm/2in)
= 2 cm
C) The original scale drawing, the microchip was 6 inches long. It is now 9 inches long.
Ratio: 6in/9 in 3in/2in
The microchip was 4 inches wide. In the new scale drawing, the microchip is 6 inches wide.
Ratio: 4in/6in 2in/3in
(THIS MY FINAL DAY AT SCHOOL SO I NEED HELP)
Answer:
D. (1/3)
Step-by-step explanation:
If we look at the graph, there are a total of 12 squares, which means we have a denominator of 12.
Next if we look at the answer, it is asking if for the chance of us getting a number under 5 and is a heads, which means there are 4 squares that would apply to this (They have to be both under 5 and be a heads)
This results in us having a numerator of 4.
So If we put it together we get 4/12, which when simplified equals 1/3!
