Music stalls Games stalls Handicraft stalls Ks 3000 Food stalls Ks 4800 (a) How much money was collected by the music stalls? (b) What fraction of the total amount of money was collected by the game stalls? (c) What percentage of the total amount of money was collected by the food stalls? (d) What was the ratio of the money collected by the handicraft stalls to the money collected by the music stalls?
Answers
Answer:
Step-by-step explanation:
a. The music stalls collected Ks 3000.
b. The game stalls collected Ks 4800, which is a fraction of the total amount of money collected. To find the fraction, we can divide the amount collected by the game stalls by the total amount collected by all the stalls:
$\frac{Ks 4800}{Ks 3000 + Ks 4800 + Ks 3000} = \frac{Ks 4800}{Ks 10800} = \frac{2}{9}$
Therefore, the game stalls collected $\frac{2}{9}$ of the total amount of money.
c. The food stalls collected Ks 4800, which is a percentage of the total amount of money collected. To find the percentage, we can divide the amount collected by the food stalls by the total amount collected by all the stalls and multiply by 100%:
$\frac{Ks 4800}{Ks 3000 + Ks 4800 + Ks 3000} \times 100% = \frac{Ks 4800}{Ks 10800} \times 100% = 44.44%$
Therefore, the food stalls collected 44.44% of the total amount of money.
d. The handicraft stalls collected Ks 3000, and the music stalls collected Ks 3000. The ratio of the money collected by the handicraft stalls to the money collected by the music stalls is therefore 1:1. We can write this ratio as $\frac{1}{1} = 1$, or simply as 1.

The amount of acid in the solution will be: 55.4 millimeters
Step-by-step explanation:
The total amount of solution of acid and water = 342 milimeters
The percentage of acid included in the solution = 16.2%
The amount of acid in the solution:
\(16.2\%\:\times 342\)
\(=\frac{16.2}{100}\times \:342\)
\(=\frac{162}{1000}\times \:342\)
\(=0.162\times \:342\)
\(=55.4\) millimeters
Thus, the amount of acid in the solution will be: 55.4 millimeters

The quadratic equation of the graph in vertex form is:
f(x) = 2(x - 5)² + 2
How to find the equation of the quadratic function?The general for of expression of the equation of quadratic function whose vertex is (h, k), is:
f(x) = a(x - h)² + k
The coordinates of the vertex shown on the graph is: (5, 2)
Thus, we have:
f(x) = a(x - 5)² + 2
Now, we see that the graph passes through the point (6, 4) and as such we will have:
4 = a(6 - 5)² + 2
4 = a + 2
a = 4 - 2
a = 2
Thus, the quadratic equation in vertex form is:
f(x) = 2(x - 5)² + 2

April and Blake went running. Blake
ran 4 miles farther than April. Added
together, they ran a total of 16 miles.
How far did April run?
X = April's distance
4 + x = Blake's distance
Answers
Answer:
6 miles
Step-by-step explanation:
From the information given you can write the following equation:
x+y= 16 (1), where
x= April's distance
y= Blake's distance
You also have that Blake ran 4 miles farther than April which means that y= 4+x and you can replace this in the first equation and isolate x:
x+(4+x)= 16
x+4+x=16
2x=16-4
x=12/2
x= 6
According to this, the answer is that April ran 6 miles.

Answers
Options A and D are true for the inverse matrices.
We need to determine which statement about inverse matrices is true.
What is an inverse matrix?The inverse of the matrix is another matrix, which on multiplication with the given matrix gives the multiplicative identity. For a matrix A, its inverse is \(A^{-1}\), and \(A.A^{-1}=I\) A = I, where I is the identity matrix. The matrix whose determinant is non-zero and for which the inverse matrix can be calculated is called an invertible matrix.
The matrix should have a non-zero determinant for getting the inverse of it.
An inverse matrix should be a square matrix.
The inverse of the matrix can be calculated by two approaches:
1) Adjoint method
2) Row/Column elementary method
Therefore, options A and D are true for the inverse matrices.

Answer:
C) 9 heads and 9 tails
Step-by-step explanation:
if a fair sided coin is tossed, the probability of obtaining either heads or tails is 50%
If the coin is tossed 18 times, we would expect to see the same probability outcome which is 50% heads and 50% tails.
which corresponds to 9 heads and 9 tails.
Answer:
Step-by-step explanation:
Each throw is independent of any other throw. The probability of getting a head or tail is 1/2, so you should expect to flip as many heads as tails. Answer C shows that even split.

A bag contains seven yellow marbles and two blue marbles. You randomly select two marbles from the bag. What is the probability that both marbles are yellow when you replace each marble before selecting the next marble? Write your answer as a decimal rounded to the nearest thousandth. Brainliest to best answer
Answers
Answer:
0.605--------------------------
The probability of selecting a yellow marble on the first draw is 7/9, since there are 7 yellow marbles out of 9 total marbles.
Since we replace the marble before the second draw, the probability of selecting a yellow marble on the second draw is also 7/9.
To find the probability of both events happening together, we multiply the probabilities:
P(both yellow) = (7/9) x (7/9) = 49/81 = 0.6049382716Rounding to the nearest thousandth, the answer is 0.605.

HELP PLS
Answers
Chris' gross pay for the week after selling computer equipment worth $17,000 is $2,600.
How is the gross pay determined?The gross pay is the addition of the base pay and the sales commission.
The sales commission is graduated and computed as follows:
Chris' base pay = $300
Sales Commissions:
First $5,000 = 10%
Above $5,000 = 15%
Last week's sales = $17,000
10% Commission = $500 ($5,000 x 10%)
15% Commission = $1,800 ($17,000 - $5,000 x 15%)
Total Commission = $2,300
Gross pay = Base Pay + Commission
= $2,600 ($300 + $2,300)

Lol, i know this is really confusing, just look up surface area of a cone formula.
Height squared = 15 * 15 = 225
Radius squared = 8 * 8 = 64
225 + 64 = 289
The square root of 289 is 17
17 + 8 = 25
3.14 * 8 = 25.12
