D: 3 over 4
Answer: 1 is correct
2 is correct
3 is correct
4 is correct
5 is correct
6 is correct
7 is correct
8 is wrong it should be because you wouldn't add you would subtract it and the other number is negative so it would be x=-26
9 is correct
10 is correct
13 is correct
14 I think is correct
I think 15 is incorrect because if he says one less than twice the number of last year then I think you first should subtract 1 from 25 and then divide by 2 this would give you 17 packages
and I think 16 is correct too.

Answer:
a/
36s ~ 360º
1s ~ ?
so 1 * 360 / 36 = 10º
b/
36*3/4=27s (closest)
36*1/4=9s (farthest)
c/
20ft
Answer:
a) 10°
b) closest: 27 seconds
farthest: 9 seconds
c) 20 ft
Step-by-step explanation:
a) Angles around a point add up to 360°, therefore 1 rotation = 360°
If it makes one rotation in 36 seconds, then there are 10° per second as 360/36 = 10
b) closest to wall: this will be a 3/4 rotation:
3/4 of 36 seconds = 0.75 x 36 = 27 seconds
farthest from wall: 1/4 rotation:
1/4 of 36 = 0.25 x 36 = 9 seconds
c) 18 seconds is half of 36 seconds. Therefore, you will have made a 1/2 rotation. So you will be on the same horizontal plane as the start position, but on the opposite side of the circle (see attached diagram).
Therefore, you will be 20ft away from the wall (shown in blue).

There are 138 paperclips in the jar. Ashley adds 157 more paperclips to the jar. Estimate how many paperclips are now in the jar.
Answer:
295
Step-by-step explanation:
138+157=295
Answer:
There are 300 paperclips now in the jar.
Step-by-step explanation:
138 + 157 = 295. If you have to estimate, 5 rounds up so you estimate it up to 200.
There are 300 paperclips now in the jar.
If it does not want you to round, answer 295.

Answer:
D
Step-by-step explanation:
A recursive formula lets us calculate a term in the sequence by multiplying the previous term by the common ratio r
for the sequence
- 3, 9 , - 27 , 81....
the common ratio r is
r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 3
Then the recursive formula is
f(n) = - 3 f(n - 1) if n > 1
f(1) = - 3
option D
Answer:
D)
Step-by-step explanation:
A recursive formula always has two parts: the value of an initial term (or terms), and an equation defining [tex]a_n[/tex] in terms of preceding terms.
From inspection, the initial term is -3
[tex]\implies a_1=-3[/tex]
[tex]\implies f(1)=-3[/tex]
From inspection, we can see that each term is the preceding term multiplied by -3. Therefore, the sequence can be defined as:
[tex]a_n=-3(n-1)[/tex]
[tex]\implies f(n)=-3f(n-1)[/tex]
So the recursive formula for the sequence is D)
[tex]f(n)=\left \{ {{f(1)=-3} \atop {f(n)=-3f(n-1)}} \right.[/tex]

Find the intersection of the line and the circle
Answer:
(-8, 8)
Step-by-step explanation:
Plug in the y from the top equation into the y of the bottom equation
x² + (x + 16)² = 128
x² + x² + 32x + 256 = 128
Subtract 128 from both sides to make it equal to zero
2x² + 32x + 256 = 128
- 128 - 128
2x² + 32x + 128 = 0
Divide both sides by 2
(2x² + 32x + 128)2 = 0/2
x² + 16x + 64 = 0
Factor the equation
(x + 8)(x + 8) = 0
We see that x will have to be -8 for it to equal zero
so x = -8
Plug the new x into one of the original equations; let's use the top one
y = -8 + 16
y = 8

You are building a dog house and need a supporting block of wood for the roof. Your
boss went on a errand and took your measuring tape. Using the Pythagorean theorem
determine the length needed. If necessary, express your answer in its simplest radical
form.
Answer:
x = 8[tex]\sqrt{3}[/tex] in
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 22² = 26²
x² + 484 = 676 ( subtract 484 from both sides )
x² = 192 ( take square root of both sides )
x = [tex]\sqrt{192}[/tex] = [tex]\sqrt{64(3)}[/tex] = [tex]\sqrt{64}[/tex] × [tex]\sqrt{3}[/tex] = 8[tex]\sqrt{3}[/tex] in

The point D(4,
–
6) is rotated 180° clockwise around the origin. What are the coordinates of the resulting point, D'?
Answer:
(-4,-6)
Step-by-step explanation:
If your point D were to start at (4,6), the first 90° clockwise rotation would have the point land on (4,-6), the second would have point D land on (-4,-6). A faster way to do this without making 2 90° clockwise rotations, is you flip it diagonally across the center point, if the center point is 0, you would flip both signs (positive would become negative and the other way around).
The rotation of point about 180 degree is D(4, 6)----> D'(4, -6).
What is Transformation?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
We have,
The points D(4, 6).
We know the rule for 180 degree rotation is
(x, y) ----> (x, -y).
So, the rotation of point about 180 degree is
D(4, 6)----> D'(4, -6).

Answer:
Step-by-step explanation:
Euclid Street is parallel to Lambert Street. City Hall is
located between the streets. From City Hall, a straight
road leads to Euclid Street, intersecting it at a 51°
angle. Another straight road leads to Lambert Street,
intersecting it at a 37° angle. Find X. EXPLAIN and
show your method.
Answer:
88
Step-by-step explanation:
Imagine a line through City Hall parallel to the given streets. The angle between that and the path to Euclid Street is 51°, congruent with the alternate interior angle marked 51°.
The angle between our imaginary line and the path to Lambert Street is 37°, congruent with the alternate interior angle marked 37°.
The value of x° is the sum of those two angles:
x° = 51° +37°
x = 88
__
Alternate solution
If you extend the path to Euclid Street until it intersects Lambert Street, the alternate interior angle theorem tells you the angle it makes with Lambert Street is 51°. The angle x° is an external angle to the triangle that now has 51° and 37° as remote interior angles. As such, x is the sum of 51 and 37:
x = 51 +37 = 88
