D. 6x² +67² = 144
The equation that produces the circle in the given graph is; x² + y² = 16
How to interpret the equation of a Circle?
The general form of equation of a circle is;
(x - h)² + (y - k)² = r²
where;
h, k are coordinates of the circle center
r is the radius
From the graph, we can see that the coordinates of the center is; (0, 0).
Also, radius is;
r = √(4² - 0²)
r = √16
Thus, our equation of the circle in the graph is;
(x - 0)² + (y - 0)² = (√16)²
⇒ x² + y² = 16

Answer:
7, 8, 9, 10, 11 (Answer to boxes from left to right
Step-by-step explanation:
For each problem, we just "plug in" the x value into the equation. For example, in the first box the x value is 2 and the equation is y = x + 9. Since we know that x is equal to -2, then the equation becomes y = -2 + 9, and y becomes 7.

Two consecutive integers have a sum of 75. Find the integers.
Answer:
37 and 38
Step-by-step explanation:
let the consecutive integers be x-1 and x
If their sum is 75
x-1+x = 75
2x - 1 = 75
2x = 75+1
2x = 76
x = 76/2
x = 38
First integer = x - 1
First integer = 38-1 = 37
Second integer is 38
Hence the integers are 37 and 38

The width of the rectangle
is one-fourth of its length.
If the perimeter is 40 cm,
find the dimensions of the
rectangle.
4w = L
2L + 2w = 40
Answer:
84cm^2
Step-by-step explanation:
P=2l+2w
We are given,
P=40cm
l=2w+2
Plug these into the first formula and solve for the dimensions,
length and width, of the rectangle:
40=2(2w+2)+2w Simplify
40=4w+4+2w
40=6w+4
36=6w
6=w OR the width is 6cm, therefore,
the length is
l=2(6)+2
l=14cm
To calculate the area of a rectangle, A=lw,
plug the length,14cm, and the width, 6cm, into this formula
A=(14)(6)
A=84cm2 OR the area of the rectangle is 84cm^2
Maria has 6 ⅛ cups of flour, but only needs 4 ¼ cups for her recipe. How much will she have left?
Find the perimeter of a rectangle if
the area is 45 cm2 and the base is 7.5 cm
Answer:
27 cm.
Step-by-step explanation:
Area = base * height
45 = 7.5 * h
h = 45/7.5
= 6 cm.
So the perimeter
= 2(base + h)
= 2(7.5 + 6)
= 27 cm.
Damien needs to order more pill containers for the pharmacy. Currently, there are 156 8-dram bottles, 78 20-dram bottles, and 132 30-dram bottles. All the bottles come in cases of 140 bottles. The pharmacist wants all stocks to be replenished so that there are at least 400 of each bottle type. How many cases of each bottle type does Damien need to order
Answer:
for 8 gram bottle = 2 cases
for 20 gram bottle = 3 cases
for 30 gram bottles = 2 cases
Step-by-step explanation:
Determine how many cases of each bottle type Damien needs to order
i) For 8-gram bottles
available bottles = 156
required amount ≥ 400
extra bottles to be ordered = 400 - 156 = 244 bottles
since case contains 140 bottles , the number of cases to be ordered
= 244 / 140 = 1.74 cases ≈ 2 cases
ii) for 20 gram bottles
available bottles = 78
required amount ≥ 400
Extra bottles to be ordered = 400 - 78 = 322 bottles
therefore the number of cases = 322 / 140 = 2.3 cases ≈ 3 cases
iii) For 30 gram bottles
available bottles = 132
required amount ≥ 400
Extra bottles to be ordered = 400 - 132 = 268
therefore the number of cases = 268 / 140 = 1.9 ≈ 2 cases

) solve the equation and explain A. 3(10−)=6
Answer:
The solution to the equation is [tex]x = 8[/tex]
Step-by-step explanation:
To solve the equation, first we apply the distributive property on the parenthesis, then we isolate x.
Solution:
[tex]3(10 - x) = 6[/tex]
Applying the distributive:
[tex]3*10 - 3*x = 6[/tex]
[tex]30 - 3x = 6[/tex]
Solving for x
[tex]3x = 30 - 6[/tex]
[tex]3x = 24[/tex]
[tex]x = \frac{24}{3}[/tex]
[tex]x = 8[/tex]
The solution to the equation is [tex]x = 8[/tex]

A commercial jet flies 1,500 miles with the wind. In
the same amount of time it can fly 1,000 miles against the
wind. The speed of the jet in still air is 550 mph. Find the
speed of the wind.
Answer:
As below
Step-by-step explanation:
we want to know how long it took to fly so make two equations and set them equal to each other using the variable t
so, use d = r*t where d= distance , r= rate ( speed) and t = time
w= wind velocity (speed with direction)
1500=(w+550)*t
1000=(-w+550)*t
now make both equations with respect to t
1500/(w+550) = t
1000/(-w+550) = t
since they are both equal to t, where t is the same amount of flying time, set the two equations equal to each other
1500/(w+550) = 1000/(-w+550)
now solve for w
1500w + 825,000 = -1000w+550,000
2500w= -275,000
w = - 110
the wind speed is 110 opposite of the planes direction but also, if the plane flies in the other direction with it.
wind velocity (velocity is speed with a direction ) is 110 MPH
they are asking for speed, b/c we don't know anything about direction... that is which direction is the plane headed during it's flight therefore we also can't say anything about the wind direction either. :|

If a hockey player takes 78 shots and scores 16 goals, what would be the probability of this player scoring a goal on their next shot?
0.173
0.205
0.013
0.263
Answer:
0.205
Step-by-step explanation:
This is a question of experimental probability, in which the probability from the previous outcomes is the probability for the next outcome.
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this question:
16 goals on 78 shots. So the probability of the player scoring a goal in the next shot is:
16/78 = 0.205
Answer:
0.205

Select all the expressions that are equivalent to -2(5x - 1) + 7(5x - 1) - 3(-5x + 1)
A. -2(5x - 1) + 7(5x - 1) - 37-5x-1)
B. (5x-1) (2 + 7-3)
C. (5x-1) (-2+ 7 + 3)
D. 40x - 8
E 10x + 2
Answer:
D. 40x - 8
C. (5x-1)(-2+7+3)
----------------------------------------------
-2(5x - 1) + 7(5x - 1) - 3(-5x + 1)
= -10x + 2 + 35x - 7 +15x - 3
= -10x - 35x +15x + 2 - 7 - 3
= 40x - 8
D. is correct.
----------------------------------------------
(5x-1)(-2 + 7 + 3)
= -10x + 2 + 35x - 7 +15x - 3
= 10x - 35x +15x + 2 - 7 - 3
= 40x -8
which is as same as the answer choice D. and the answer you get from solving the -2(5x - 1) + 7(5x - 1) - 3(-5x + 1), so
C. is correct, too
-------------------------------------------------
There seems to be a typo in answer choice A. so I cannot determine if A is also correct or not...

consider the figure shown below. Match the angles given in the first column with their equivalent degree Measure given in the first row
Answer:
∠3 = 115°
∠8 = 75°
∠6 = 105°
∠11 = 115°
∠9 = 65°
∠4 = 65°
Step-by-step explanation:
∠3 = 180 - 65 =115° because they are supplementary
∠8 = 75° because it is vertical to 75°
∠6 = 180 - 75 = 105° because they are supplementary
∠11 = 115° because it is corresponding to ∠3
∠9 = 65° because it is corresponding to ∠1
∠4 = 65° because it is vertical to 65°
Applying the definition of special angle pairs, the given angles and their respective equivalent degree measures are:
m<3 = 115°m<8 = 75°m<11 = 115°m<9 = 65°m<4 = 75°Given the following:
m<1 = 65°m<5 = 75°Thus:
<3 and <1 are supplementary angles, therefore,
m<3 = 180° - 65°
m<3 = 115°
<8 and <5 are vertical angles, therefore,
m<8 = 75°
<6 and <8 are supplementary angles, therefore,
m<6 = 180° - 75°
m<6 = 105°
<11 and <3 are corresponding angles, therefore,
m<11 = 115°
<9 and <1 are corresponding angles, therefore,
m<9 = 65°
<4 and <2 are vertical angles, therefore,
m<4 = 75°
