Answer:
1.21 kilograms
Step-by-step explanation:
Let y represent the mass of the empty basket, and x represent the mass of each ball
Create a system of equations:
3x + y = 3.64
5x + y = 5.26
Solve by elimination by multiplying the top equation by -1
-3x - y = -3.64
5x + y = 5.26
Add them together, then solve for x:
2x = 1.62
x = 0.81
Plug this back into one of the equations and solve for y:
3x + y = 3.64
3(0.81) + y = 3.64
2.43 + y = 3.64
y = 1.21
So, the mass of the empty basket is 1.21 kilograms

A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 18% are pennies and 36% are dimes. There are 2 more nickels than pennies. How much money does the bag contain?
Answer: $5.44
Step-by-step explanation:
18% of 50= 9 pennies
36% of 50= 18 dimes
9 + 2= 11 nickels
9+18+11= 38 pennies, nickels and dimes.
50 (total amount of coins) - 38 (pennies nickels and dimes)= 12 quarters.
9 pennies= 9 cents
18 dimes= 180 cents
11 nickels= 55 cents
12 quarters= 300 cents
9 + 180 + 55 + 300= 544 cents= $5.44
Answer:
$5.44
The bag contains $5.44.
Step-by-step explanation:
Pennies:
50(18/100)= 9 pennies
Dimes:
50(36/100)= 18 dimes
Nickels:
2 more nickels than pennies
9+2= 11
Quarters:
9+18+11= 38
50-38= 12 quarters
1 penny = 0.01 dollar
9x0.01= 0.09
1 dime = 0.10 dollar
18x0.10= 1.80
1 nickel = 0.05 dollar
11x0.05= 0.55
1 quarter = 0.25 dollar
12x0.25= 3
0.09+1.80+0.55+3= $5.44

Answer:
Y=-6x
Step-by-step explanation:
Choose two points from the graph (0,0) and (1,-6)
Average Rate of Change= (y2-y1)/(x2-x1)
(-6-0)/(1-0)=-6/1=-6
y=-6x+b
0=-6(0)+b
0=0+b
0=b
Y=-6x+0
Y=-6x

A rectangular prism has a length of 714 inches, a width of 612 inches, and a height of 10 inches.
Raj has another prism that has dimensions that are each double the dimensions of the first rectangular prism.
How many times greater is the volume of the larger prism than the volume of the smaller one?
Answer:
8 timesStep-by-step explanation:
The volume of the prism:
V = lwhIf each of the dimensions is doubled, then the volume becomes:
V₁ = 2l*2w*2h = 8lwh = 8VThe larger prism has 8 times greater volume

Hey can u help with the following questions because I don't get this.
Answer:
median- 58.5
first quartile- 56
third quartile- 65
interquartile range- 9
Step-by-step explanation:
median is when you put the numbers from least to greated and find the middle number; so, you will put this set in that order= 38, 46, 55,56,58,59,61,65,67,75. now, you get stuck between 58 and 59. so you add them and divide by two to get 58.5. thats the median. The first quartile is any number from the set that is smaller than the median, basically the first half of it. now you will just find the median of that which is 56. that is your first quartile. third quartile is the second half of the set, any number in the set that is greater than the median. you will find the median of that half to get 65. that is your 3rd quartile. interquartile range ius the difference bewteen your first and third quartile. 65-56 is 9. hope this helped marck as brainlyest and help me with my que tooo :)
Please need help on this one h as be no clue how to do this
Answer:
y = -2x
Step-by-step explanation:
Equation in slope-intercept form is y = mx + b.
m = slope = ∆y/∆x
Using any two points on the line, say (0, 0) and (-20, 40),
Slope (m) = (40 - 0) / (-20 - 0) = 40/-20
Slope (m) = -2
b = y-intercept = the value of y when x = 0.
b = 0
To write the equation of the line, substitute m = -2 and b = 0 into y = mx + b
Thus:
y = -2x + 0
y = -2x
In the expression, x^2 + 6x + 9, which is the coeffcient?

Answer: 6
Decide whether or not it is a function.
Answer:
Step-by-step explanation:
Yes it's a function.
You may be looking at v which produces m
You may be looking at r which also produces m.
That's fine. Two different x values (the domain) can produce the same y value. Lots of functions do that. (you'll study parabolas pretty soon and all that open up or down have two x values producing the same y value).
If you have a member of the domain producing 2 y values, that doesn't work. That would not be a function.
This example is a function.

4. In triangle ABC, AC=11,BC=24, and m
a. 40
b. 46.3
c. 20.5
d. 23.7
Answer:
23.7°
Step-by-step explanation:
To obtain the value of AB ; Use the cosine rule ;
Recall:
c² = a² + b² - 2ab Cos C
c² = 24² + 11² - 2*24*11 Cos75
c² = 576 + 121 - 528 * 0.2588190
c² = 697 - 136.656432
c² = 560.343568
c = sqrt(560.343568)
c = 23.6715
Hence, c = AB = 23.7°
