Answer:
12cm
Step-by-step explanation:
pythagorean theorem!
a^2 + b^2 = c^2
7^2 + b^2 = 13^2
49 + b^2 = 169
49 - 49 + b^2 = 169 - 49 (whatever you do to one side, you do to the other side)
b^2 = 147 (square root)
= 12cm

Lucy has a budget for school stationery of 33, but has already spent 22.47 on books and folders. Let p represent the amount that Lucy can spend on other stationery. Write an inequality that shows how much she can spend on other stationery, and solve for p.
Answers
Answer:
The inequality is;
p≤ 10.53
where 10.53 is the highest value she can spend on other stationery
Step-by-step explanation:
Here, we want to write an inequality
The amount she has to spend is 33
This means she can spend less than or equal to this amount
she has spent 22.47 and still has p to spend
Mathematically;
p + 22.47 ≤ 33
p ≤ 33-22.47
p ≤ 10.53
Write an equation of the line passing through point (7,3) that is parallel to line 4x-7y=9
Answers
Answer:
y= 4/7x -1
Step-by-step explanation:
solve for y first in 4x-7y=9, which becomes y = 4/7x - 9/7, then since its a parallel line the slope stays the same which is 4/7. Then plug into this equation: y =mx+b, in which you plug in the point for the x and y values and you plug in the slope for m, so the equation becomes, 3 = (7)(4/7) + b and now solve for b in which b = -1 and now write the equation using all the corresponding things so the equation becomes: y= 4/7x -1

Megan cut a string into 4 equal pieces. Each piece is 4 fifths of a foot long. How many feet long was the string before Megan cut it? Enter your answer as a mixed number in the solution box. The string was feet long before Megan cut it.
Answers
Answer:
[tex]Total = 3\frac{1}{5}ft[/tex]
Step-by-step explanation:
Given
[tex]Pieces = 4[/tex]
[tex]Size = \frac{4}{5}ft[/tex]
Required
Determine the total size of the string
To do this, we multiply the number of pieces by the length of each piece.
[tex]Total = Pieces * Size[/tex]
[tex]Total = 4 * \frac{4}{5}ft[/tex]
[tex]Total = \frac{4 * 4}{5}ft[/tex]
[tex]Total = \frac{16}{5}ft[/tex]
Convert to mixed number
[tex]Total = 3\frac{1}{5}ft[/tex]

Step-by-step explanation:
i just took the test
The explicit formula that represents the situation is [tex]a_{n}[/tex] = 11 + 4n thus option (A) is correct.
What is the pattern?A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.
Another example is 2,4,16,256 in this pattern each term is the square of the previous term and this will become its specific pattern.
As per the given,
Cost of a tie-dye kit + 1 T-shirt = $15
Additional T-shirt = $4
This, means,
Cost of a tie-dye kit + $4 = $15
Cost of a tie-dye kit = $11
The total cost with n number of T-shirts will be as,
[tex]a_{n}[/tex] = 11 + 4n
Hence "The explicit formula that represents the situation is [tex]a_{n}[/tex] = 11 + 4n".

Mildred classifies the following system of equations.
y = 4x + 3
y = 6x + 1
Select Correct or Not correct for each statement.
Statements:
The system is consistent because the slopes and the y-intercepts are different.
The system is independent because the slopes and the y-intercepts are different.
Answers
The first statement is correct and the second statement is not correct as it is derived from the first statement,
We are given two equations;
y = 4x + 3
y = 6x + 1
From the equation of line in slope intercept form, the formula is;
y = mx + c
where;
m is slope
c is y intercept.
Thus, in the 2 equations given, we can see that the slopes and y-intercepts are differentNow, when two equations have different slopes and different slopes, the system is said to have only one solution and can be said to be consistent.Now, a system is only said to be independent if it is consistent and has exactly one solution.This means independency of an equation depends on if it is consistent and has exactly one solution.
Thus, in conclusion, the first statement is correct and the second one is not correct as it is derived from the first statement,

What is the length of line segment BC
Answers
Answer:
BC = 1
Step-by-step explanation:
AB = x + 16
BC = x +6
AB + BC = AC
x + 16 +x + 6 = 12
x + x + 16 + 6 = 12
2x + 22 = 12
2x = 12 - 22
2x = -10
x = -10/5
x = - 5
BC = x + 6 = - 5 + 6 = 1
Answer:
BC = 1
Step-by-step explanation:
Frm the diagram
AB + BC = AC , substitute values
x + 16 + x + 6 = 12
2x + 22 = 12 ( subtract 22 from both sides )
2x = - 10 ( divide both sides by 2 )
x = - 5
Thus
BC = x + 6 = - 5 + 6 = 1

A local fish market is selling fish and lobsters by the pound. The fish, f, costs $5.00 a pound, while the lobster, l, costs $8.00 a pound. The fish market sells 20.5 pounds and makes $131.00. How many pounds of fish and pounds of lobster did the market sell?
Answers
Given :
A local fish market is selling fish and lobsters by the pound. The fish, f, costs $5.00 a pound, while the lobster, l, costs $8.00 a pound. The fish market sells 20.5 pounds and makes $131.00.
To Find :
How many pounds of fish and pounds of lobster did the market sell.
Solution :
Let, pounds of fish sells are x.
So, pounds of lobsters sells are (20.5 - x) .
Total amount of spend = 5x + 8( 20.5 - x)
5x + 8( 20.5 - x) = 131
5x - 8x + 164 = 131
3x = 33
x = 11
Therefore, number of pounds of fish and lobsters are 11 and 9.5 pounds respectively.
Hence, this is the required solution.
John says the transformation rule (x, y) Right-arrow (x + 4, y + 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2). What was his error?
Answers
Answer:
Instead of moving right 4 times and up 7 times, John moved left 4 times and down 7 times.
Step-by-step explanation:
(x + 4, y + 7) = Right 4, Up 7
NOT
(x - 4, y - 7) = Left 4, Down 7
Answer:
The transformation rule should be applied to the pre-image. The application of the rule results in the point (8, 12). The transformation rule was applied to the wrong point.
Step-by-step explanation:
Sample Response:The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.
