Answer:
Bobby has 45 beads
Step-by-step explanation:
Let x be the number of beads Bobby has.
Then, (x + 30) is the number of beads Alvin has.
Then, 3 (x + 30) is the number of beads Cathy has.
3 (x + 30) + (x + 30) + x = 345
3x + 90 + x + 30 + x = 345
5x + 120 = 345
5x = 225
x = 45
Therefore, Bobby has 45 beads.
In Mr. Kagame's Algebra 1 class, 7 students took the Unit 7 test. The class average was 78% (rounded). Six students' scores are known:HELPPP
The score of the seventh student will be given by:
[tex]x = 546 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6[/tex]
What is the score of the last student?
So you know the scores of 6 of the students, let's define these as:
a₁, a₂, a₃, a₄, a₅, a₆.
And let's define x as the score of the 7th student.
We know that the average of the scores is 78% (rounded).
Then we can estimate the value of x using the average equation:
[tex]\frac{a_1 + a_2 + a_3 + a_4 + a_5 + a_6 + x}{7} = 78[/tex]
Now you can solve that for x, to get:
[tex]x = 78*7 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6\\\\x = 546 - a_1 - a_2 - a_3 - a_4 - a_5 - a_6[/tex]
That is the equation to get the score of the seventh student as a function of the six known scores.

To find the next number in the sequence: 7, 10, 13, 16,
you would need to do which of the following?
Divide 16 by 3
add 13 to 16
Multiply 16 by 3
add 3 to 16
Answer:
The answer is add 3 to 16
Step-by-step explanation:
Because if you notice the process by which the number is following from the beginning, we notice that 3 is being added to each number and by this we get the hint that the next number,3 will be added to it automatically because it's a process.
Suppose the distributor charges the artist a $50.00 cost for distribution, and the streaming services pay $ 5.00 per unit. (Note: One unit = one thousand streams) Model the profit for the total number of streams by answering the questions below:
1. Use the cost for distribution to build the y-intercept. What is the y-intercept?
Hint: the y-intercept is a point on the y axis, so the answer should be an ordered pair
(x,y). Keep in mind that money is being spent, and therefore must be deducted from the profit. If the y-intercept is incorrect, all related numbers will be incorrect.)
2. Use the payment per unit to build the slope. What is the slope?
Equation in slope intercept form
y=mx+by=5x+50Slope:-m=5
Y intercept=b=50
The y-intercept of the function is (0, 50) and the slope of the function is 5
How to calculate the slope and y-intercept of a function?Slope is defined as the rate of change of function. Given the following parameters
Fixed price = $50
If the streaming services pay $ 5.00 per unit, then the rate of change is $5
The required profit for the total number of streams is given as:
P(x) = 50 + 5x
1) The y-intercept is the point where the value of x is zero
P(x) = 50 + 5x
P(0) = 50 + 5(0)
P(0) = 50
Hence the y-intercept of the function is (0, 50)
For the slope
mx = 5x
m = 5
Hence the slope of the function is 5

4b) Find the area of the following shapes.
Answer:
180
Step-by-step explanation:
To find the area of the rectangle, multiply 15 by 9
15 x 9 = 135
To find the area of the triangle, multiply 15 by 6, then divide by 2
15 x 6 = 90
90/2 = 45
Now add these two numbers to get the total area.
135 + 45 = 180

7. A card is randomly drawn from a standard deck of shuffled cards. What are the ODDS that the
card drawn is a Letter card?
A. 12.5%
B. 75%
C. 25%
D. 44%
There are 16 total "letter cards" (1 ace and 3 face cards per suit), so the probability of drawing a letter card is 16/52 = 4/13.
There are 52 - 16 = 36 non-letter cards, with probability 36/52 = 9/13 of being drawn.
Then the odds of drawing a letter card is the ratio of these probabilities,
(4/13) / (9/13) = 4/9 ≈ 44%
Write these values in order, starting with the smallest.
0.15
1/10
12%
1/20
Rewrite them all as a decimal to compare them:
0.15
1/10 = 0.10
12% = 0.12
1/20 = 0.20
Now write them in order : 1/10, 12%, 0.15, 1/20

Higher Order Thinking Molly and five
friends picked a total of 300 oranges. If
they each picked the same number of
oranges, how many oranges did Molly
pick? Explain.
There are 50 oranges did Molly pick.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Higher Order Thinking Molly and five friends picked a total of 300 oranges.
Now,
Since, Number of oranges = 300
And, Number of persons = 6
Hence, Number of oranges picked by each person = 300 / 6
= 50
Thus, There are 50 oranges did Molly pick.

Find all real solutions Tan pi/3 x-3=0
Step-by-step explanation:
If the question is like this,
[tex] \tan( \frac{\pi}{3}x - 3 ) = 0[/tex]
We take the arc tan of both sides.
[tex] \tan( - 1) ( \tan( \frac{\pi}{3}x - 3 ) = \tan {}^{ - 1} ( {}^{ }0 ) [/tex]
[tex] \frac{\pi}{3} x - 3 = 0[/tex]
[tex] \frac{\pi}{3} x = 3[/tex]
[tex] = \frac{9}{\pi} [/tex]
Since the period of a tan function, is pi, we divide pi by pi/3 since pi/3is the coeffeicent of the x variable
[tex] \frac{\pi}{ \frac{\pi}{3} } = 3[/tex]
So the answer is
[tex] \frac{9}{\pi} + 3n[/tex]
If this the question,
[tex] \tan( \frac{\pi}{3} x) = 3[/tex]
[tex] \frac{\pi}{3} x = 1.249[/tex]
[tex]x = \frac{3.747}{\pi} [/tex]
The period is once again 3 so we have
[tex] \frac{3.747}{\pi} + 3n[/tex]

What single percentage change is equivalent to a 9% increase followed by a 17% increase?
Answer:
27.53%
Step-by-step explanation:
Initial number = 100
9% increase
100*1.09= 109
17% increase
109*1.17= 127.53
The difference with the initial number is:
127.53 - 100 = 27.53
27.53/100*100% = 27.53%
This is the single percentage change
