Answer:
Step-by-step explanation:
Amount paid for first 100 watches = (65% of 80) *100
[tex]=\frac{65}{100}*80*100\\\\= 65*80\\= 5200[/tex]
Amount paid for next 50 watches = (55% of 80) * 50
[tex]= \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200[/tex]
Remaining watches = 280 -(100+ 55)
= 280 - 155 = 125
Amount paid for 125 watches = (45% of 80) *125
[tex]= \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500[/tex]
Amount received by the watch maker = 5200 + 2200 + 4500

The width of a rectangle is x. Its length is 3x. How long is the diagonal of the rectangle? Express your answer in simplified radical form.
Answer:
The length of the diagonal is x√10
Step-by-step explanation:
Here, we want to find the length of the diagonal
The diagonal will represent the hypotenuse of a triangle formed with the width and length of the triangle being the measure of the other sides
Mathematically, we then apply Pythagoras’ theorem to get this
we have this as that the square of the diagonal equals the sum of the squares of the two other sides
d^2 = x^2 + (3x)^2
d^2 = x^2 + 9x^2
d^2 = 10x^2
d = √(10x^2)
d = x√10

A new bagel store opened. The first day 15 customers entered the store. The number of
customers that enter the store triples each day after. Which function represents f(d), the
number of customers that enter on the d day?
1.
f(d) = 3(15)
2.
f(d) = 3d + 15
3
f(d) = 150 + 3
f(d) = 15(3)
Submit Answer
Answer:
[tex]f(d) = 15 + 3d[/tex]
Step-by-step explanation:
Given
[tex]a = 15[/tex] --- day 1
[tex]Rate = 3[/tex] -- i.e. triples daily
Required
Determine the function f(d)
The number of customers on a particular day is:
Customers = Day 1 + Rate * Number of days
Represent as a function:
[tex]f(d) = a + Rate* d[/tex]
Where d is the number of days.
So, we have:
[tex]f(d) = 15 + 3* d[/tex]
[tex]f(d) = 15 + 3d[/tex]

Answer:
The set of factors of 20 is {1, 2, 4, 5, 10, 20} and the set of factors of 16 is {1, 2, 4, 8, 16}. {1, 2, 4, 5, 10, 20} ∩ {1, 2, 4, 8, 16} = {1, 2, 4} which has greatest value 4. So, GCF(20, 16) = 4.
Step-by-step explanation:
Answer:
The factors of 20 is 1, 2, 4, 5, 10, 20
The factors of 16 is 1, 2, 4, 8, 16

The Skateboard club has 2 different colors of skateboards blue and red. Can you find the number of skateboards of each color, if the total number of skateboards is 15, and their product is 44?
Answer:
The number of skateboards of each color is 11 and 4
Step-by-step explanation:
Let x represent blue skateboards and
y represent red skateboards.
From the question, the total number of skateboards is 15, that is,
x + y = 15 ...... (1)
and their product is 44, that is,
xy = 44 ...... (2)
From equation (1),
x + y = 15
We can write that
x = 15 - y ...... (3)
Substitute this into equation (2)
xy = 44
(15-y)y = 44
15y -y² = 44
Then,
y² - 15y + 44 = 0
Solve quadratically
y² -4y -11y + 44 = 0
y(y-4) -11(y-4) = 0
(y-11)(y-4) = 0
y-11 = 0 OR y-4 = 0
y = 11 OR y = 4
Put the values of y into equation (3) for x
x = 15 - y
When y = 11
x = 15 - 11
x = 4
and when y = 4
x = 15 -4
x = 11
(4,11) and (11,4)
It is either 4 blue and 11 red skateboards OR 11 blue and 4 red skateboards.
Hence, the number of skateboards of each color is 11 and 4.
The graph of y= 3 + 2x -x is shown.
a) What are the coordinates of the turning point? I
b) What are the coordinates of the roots of the equation 3 + 2x - x = 0 ?
Answer:
Step-by-step explanation:
(1, 4)
(-1, 0), (3, 0)
The coordinate of the turning point is (1,4) and the coordinates of the roots are (-1,0) and (3,0)
How to determine the coordinate of the turning point?This is the vertex of the equation.
The equation is the given as:
y = 3 + 2x - x^2
According to the graph, the vertex is at the coordinate (1,4)
Hence, the coordinate of the turning point is (1,4)
How to determine the coordinate of the roots?The equation is the given as:
3 + 2x - x^2 = 0
According to the graph, the equation crosses the x-axis at (-1,0) and (3,0)
Hence, the coordinates of the roots are (-1,0) and (3,0)

Abigail has $30.00 to buy groceries. She needs to buy some apples, some bananas, and 3 pounds of potatoes. Fuji apples are $1.79 a pound, bananas are $0.36 each, and potatoes are $2.99 for a 3 lb. bag. If a represents the number of pounds of apples Abigail buys and b represents the number of bananas she buys, which expression represents the amount of change she receives after her purchases?
30.00 – a – b
1.79a + 0.36b + 2.99
30.00 – (1.79a + 0.36b + 2.99)

Javier solved the equation 32=2(k+4)32=2(k+4). He made a mistake in his reasoning. What is his mistake and what should he have done differently?
Answer: I am pretty sure the mistake would be where he put the variable k.
Step-by-step explanation:
You know the variable equals 8 because 2x8=32. You can change the equation to 2(32+2) Therefore, the variable diesnt equal 2, so 32=2(k+4) doesnt work. Hope this helps!!

Mei wants to solve the inequality --W < 12. How can she isolate the variable?
2
• Multiply both sides by -2 and reverse the inequality symbol.
• Multiply both sides by -2 and do not reverse the inequality symbol.
*) Divide both sides by 12 and reverse the inequality symbol.
) Divide both sides by 12 and do not reverse the inequality symbol.
Answer:
Multiply both sides by -2 and reverse the inequality symbol.
Step-by-step explanation:
To isolate w, multiply both sides by the reverse of -1/2 (because -1/2*2=1 ), which is -2
When multiplying or dividing by negatives, you must reverse the inequality symbol as well.
To isolate the variable, you multiply both sides by -2 and reverse the inequality symbol.
Isolating variables in inequalityIsolation of variables means making the variable the subject of the formula from the given expression.
Given the inequality expression -1/2 w < 12
To make w the subject of the formula, we will have to multiply both sides by -2 to have;
-1/2 w * -2 > 12 * -2
w > -24
Hence to isolate the variable, you multiply both sides by -2 and reverse the inequality symbol.
