Answer:
Fraction of the people chose a tart = [tex]\frac{13}{45}[/tex]
Step-by-step explanation:
Given - A group of people went to a coffee shop. Each person chose a
drink and a treat. number of people who chose coffee: number of
people who chose tea = 1:4. Of those who chose coffee, number of
people who chose a muffin number of people who chose a tart =
2:7. Of those who chose tea, number of people who chose a muffin
: number of people who chose a tart = 5:1.
To find - What fraction of the people chose a tart?
Proof -
Let the Total number of People went to a coffee shop = 5x
Now,
As given, number of people who chose coffee: number of people who chose tea = 1:4
⇒Total number of people who chooses coffee = [tex]\frac{1}{5}.5x[/tex] = x
Total number of people who chooses tea = [tex]\frac{4}{5}.5x[/tex] = 4x
Now,
As given,
Of those who choose coffee, number of people who chose a muffin number of people who chose a tart = 2:7
⇒Total number of people who choose muffin after coffee = [tex]\frac{2}{9}x[/tex]
Total number of people who choose tart after coffee = [tex]\frac{7}{9}x[/tex]
Also,
Given that
Of those who chose tea, number of people who chose a muffin : number of people who chose a tart = 5:1
⇒Total number of people who choose muffin after tea = [tex]\frac{5}{6}.4x = \frac{20}{6}x[/tex]
Total number of people who choose tart after tea = [tex]\frac{1}{6}.4x = \frac{4}{6}x[/tex]
∴ we get
Total number of people who chooses tart = Total number of people who choose tart after coffee + Total number of people who choose tart after tea
⇒Total number of people who chooses tart = [tex]\frac{7}{9}x[/tex] + [tex]\frac{4}{6}x[/tex]
= [tex]\frac{7}{9}x + \frac{2}{3}x[/tex]
= [tex]\frac{7x + 6x}{9}[/tex]
= [tex]\frac{13}{9}x[/tex]
⇒Total number of people who chooses tart = [tex]\frac{13}{9}x[/tex]
Now,
Fraction of the people chose a tart = [tex]\frac{People choose tart}{Total people}[/tex]
= [tex]\frac{\frac{13}{9}x }{5x}[/tex]
= [tex]\frac{13}{45}[/tex]
⇒Fraction of the people chose a tart = [tex]\frac{13}{45}[/tex]

Answer:
f (8) = ( -161 )
Step-by-step explanation:
[tex]f(x)=-3x^{2} +3x+7[/tex]
To find f(8) sub 8 for x in the equation and simplify:
[tex]f(8)=-3(8^{2} )+3(8)+7[/tex]
= -192 + 24 + 7
= -168 + 7
= -161
so f(8) = -161
What is the difference between the 12th square number and the
7th square number?
Answer:
95
Step-by-step explanation:
12th square number
= 12 × 12
= 144
7th square number
= 7 × 7
= 49
Difference between the 12th square number and the
7th square number
= 12th square number - 7th square number
= 144 - 49
= 95
Difference between the 12th square number and the
7th square number = 95
Mrs. Brown has a flower garden in the shape of a parallelogram.
The length of the base of the garden is 9.5 feet and the height is
4.2 feet. What is the area of the flower garden?
A 19.95 ft? B 27.4 f? C 30.7 ft? D 39.9 ft?
Area of flower garden is 39.9 square feet
Solution:
Given that, flower garden in the shape of a parallelogram
The length of the base of the garden is 9.5 feet and the height is 4.2 feet
To find the area of a parallelogram, multiply the base by the height
The formula for area of parallelogram is:
From given,
Base = 9.5 feet
Height = 4.2 feet
Substituting the values in formula,
Thus area of flower garden is 39.9 square feet

Answer:
t = ±√3
Step-by-step explanation:
The first equation tells us ...
x^2 +tx +2 = (x -h)(x -k)
x^2 +tx +2 = x^2 -(h+k)x +hk
Comparing coefficients, we have the equations ...
t=-(h+k)
2 = hk
__
The second equation tells us ...
2x^2 +mx +2m = 2(x -h/k)(x -k/h)
2x^2 +mx +2m = 2x^2 -2(h/k +k/h)x +2
Comparing coefficients, we have the equations ...
m = -2(h/k +k/h)
2m = 2
__
Dividing the last equation by 2 gives ...
m = 1
Using that in the third equation, we have ...
1 = -2(h/k +k/h) = -2(h^2 +k^2)/hk
Using hk = 2, this gives us ...
h^2 +k^2 = -1
From the first equation, we know ...
t^2 = (-(h+k))^2 = h^2 +2hk +k^2 = (h^2 +k^2) +2(hk)
Substituting the values for these terms, we have ...
t^2 = -1 + 2(2) = 3
t = ±√3
Possible values of t are √3 and -√3.

LMNP is rotated 180° clockwise around the origin.
Answer:
The correct answer is B
Step-by-step explanation:
-3,-4
Coordinates of M are (-3, -4) as LMNP rotates 180° clockwise.
What is clockwise rotation?
" Clockwise rotation means when any object is moving in the direction of hands of clock."
According to the question,
As per the diagram ,
Coordinates of M are ( 3, 4)
Rotation of a point through 180° about the origin when a point M( x, y) is rotated about the origin through 180° in anticlockwise or clockwise direction, it takes the new coordinates ( -x ,-y).
Therefore , coordinates of M are ( -3, -4).
Hence, coordinates of M are (-3, -4) as LMNP rotates 180° clockwise.

A regular hexagon is rotated in a counterclockwise direction about its center. Determine and state the minimum number of degrees in the rotation such that the hexagon will coincide with itself.
The minimum number of degrees in the rotation such that the hexagon will coincide with itself is 60°
What is hexagon?Hexagons are six-sided polygons in geometry. A hexagon is said to be a regular hexagon if all of its sides and angles have identical lengths. To put it another way, a regular hexagon's sides are congruent.
Given that, Around its center, a regular hexagon is rotated counterclockwise.
We are aware that a hexagon has six sides.
There are also 360 degrees.
According to the data given, the calculation is as follows:
= 360 /60
= 60 degrees.
Therefore, we may say that the rotation must be at least 60 degrees in total.

A game show contestant cannot spend more than $100 on $0.79 cans of beans and $3.59 boxes of cereal. Which inequality represents the situation, where b is the number of cans of beans and c is the number of boxes of cereal?
Answer:
i believe it would be 0.79b + 3.59c [tex]\leq[/tex] 100
Step-by-step explanation:
the price of the number of cans of beans added to the number of boxes of cereal must be less than or equal to $100
0.79b represents the price of the beans multiplied by the amount of cans the contestant buys, and 3.59c represents the price of the cereal multiplied by the amount of boxes the contestant buys
what is the amplitude of y = 3[6(x-4)] - 5
'I hope my answer helps you'
Question: y = 3cos[6(x-4)] - 5
Answer: 3
Step-by-step explanation:
The reason for this is in order to find amplitude, it's always the number before "cos" or "sin". Also, the "[6(x-4)]" was just a distraction to throw you off
Here's a trick to find everything; amplitude, period, phase sift, etc.:
y = A sin(B(x + C)) + D
* amplitude is A
* period is 2π/B
* phase shift is C (positive is to the left)
* vertical shift is D

x times x equals x^2, 2 times x equals 2x, -2 times x equals -2x, and 2 times -2 equals -4. If you add that up, the x-values cancel out, leaving the x^2 and the -4. (This explanation is working it backwards which is the easiest way IMO)
