scratched half of his CDs. He now only
has 56 working CDs left. How many
CDs did Jason start with?

He had origanlly had 68 altogether
Step-by-step explanation:
Because if u count the scrateched ones which was 6 is now 62 then add the other six because there was 12 and his brother scrateched half which is basically 12 / 2 = 6 so if u add the six is 68
What Im basically saying is 56 + 12 = 68

A coral reef grows 0.17 m every week. How much does it grow in 13 weeks?
Write your answer in centimeters.
cm
X Х

?
Meters to centimeters
Answer:
It grows 221 centimeters in 13 weeks.
Step-by-step explanation:
Each meter has 100 centimeters.
A coral reef grows 0.17 m every week
So it grows 0.17*100 = 17 cm every week.
How much does it grow in 13 weeks?
17 cm every week for 13 weeks, so
17*13 = 221
It grows 221 centimeters in 13 weeks.
Maria bought apples(a) for $2.32 per pound and bananas(b) for $1.65. She spends $31.42. Write the equation for this situation.
Answer:
$31.42-(2.32+1.65)
Step-by-step explanation:
In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equals sign "=". The word equation and its cognates in other languages may have subtly different meanings; for example, while in English, any equality is an equation. Solving an equation containing variables consists of determining which values of the variables make the equality true.

If someone knows the answer please help . Lots of points !
Answer:
Step-by-step explanation:
Given function is,
f(x) = -4(x - 3)² + 1
A). Negative sign of the coefficient (-4) tells that the parabola opens downwards.
And 4 represents that the parent function is stretched vertically by 4 units.
B). By comparing this equation with the vertex form of the quadratic function,
f(x) = a(x - h)² + k
Here, (h, k) is the vertex of parabola.
Vertex of the given parabola → (3, 1)
C). Axis of symmetry → x = 3
D). Domain of the given quadratic function → (-∞, ∞)
Range of the given function → (-∞, 1)
HELP ME, SMART PEOPLE PLEASE !!!!!! I'M IN A MENTAL CRISIS :(((((
Identify which trigonometric ratio to use. Write out the ratio then solve by cross multiplying for the length of side CA
Answer:
Cos25o
Step-by-step explanation:
since you have to find out the opposite.
1.Write the expression in expanded form. The subscript number can be write in
normal form. E.g. X1 + X1Y1, do not forget the correct parenthesis and the correct
order. *
2.For the equation in above evaluate the notation using the values below. Please
enter the exact value.
X1 =0
Y1 = 5
Z1 = 0
X2 = 1
Y2 = 26
Z2 = -2
X3 = 12
Y3 = -2
Z3 = 3
X4 = -1
Y4 = 25
Z4 = 24
Answer:
(a) Expanded form:
[tex]((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)[/tex]
(b) The value of the expression: -21
Step-by-step explanation:
Given
[tex]\sum \limit^4_{i=1}\ ((X_i+X_iY_i) - X_iZ_i)[/tex]
Solving (a): The expanded form:
This means that we substitute the values of i from 1 to 4 in the above expression.
So, the expression becomes:
[tex]((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)[/tex]
Solving (b): The value of the expression
To do this, we simply substitute the given values of X1, X2....... in the expression.
This gives:
So, the expression becomes:
[tex]((0 + 0*5) - 0*0) + ((1 + 1*26) - 1*-2) + ((12 + 12*-2) - 12*3) + ((-1 + -1*25) - -1*24)[/tex]
Simplify each bracket
[tex]((0 + 0) - 0) + ((1 + 26) +2) + ((12 -24) - 36) + ((-1 -25) +24)[/tex]
[tex]0 + 29 -48 -2[/tex]
[tex]-21[/tex]
Hence, the result of the expression is -21
Which number has the greatest value -17, -24 ,0, 23?
Answer:
23
Step-by-step explanation:
Example:
You have no money, you decide to swipe your credit card to purchase something for $17. Again, you did so for another item paying $24. You are now $41 in debt. Your mom decides to pay for your debt which is $41. You decide to actually go to your part-time job and earn $23. When was the time you had the most money in this example? When you earned the $23 becuase you started with none.
Answer:
23
Step-by-step explanation:
Out of the numbers given:
All positive numbers are greater than negative numbers.
This eliminates -17 and -24.
Comparing 0 to 23:
23 has more value than 0.
0 < 23
This means out of the numbers given, 23 has the greatest value.
Hope this helps.

Find the 110 term of the sequence -7,3, 13, 23, ..
Answer:
1083
Step-by-step explanation:
The formula for the nth term of a sequence is a+(n - 1 )d, where a is the first term and d is the difference between each term. Here, a is -7 and d is 10 (terms go up by ten each time).
So, the nth term = -7+(n-1)10 = -7+10n-10 = 10n-17
So, the 110th term = 10(110)-17=1100-17=1083
