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
What fraction of the people chose a tart?
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:
7.) m = 1/3 ; b = -2.5
8.) m = 2 ; b = 2
Step-by-step explanation:
For m, either do the rise over run method or use 2 points and do (y2-y1)/(x2-x1).
For b, just look at the y-intercept/where it crosses the y axis

Find an equation in point-slope for the line having the slope m m = - 6 and containing the point (8,6)
Answer:
y-6 = -6(x-8)
Step-by-step explanation:
Here, we want to get the equation of the line in point-slope form
The point slope form is;
y-y1 = m(x-x1)
(x1,y1) represents the slope
We have this as ;
y-6 = -6(x-8)

A sketch of a rectangular patio is shown below. A concrete triangular section is planned for an outdoor fireplace. What is the area of the concrete section, in square units? A rectangle has a width of 69. A segment is drawn from the top left corner down to a point on the bottom side, creating a right triangle. The segment, which is the hypotenuse of the triangle, is 115 units long. From the segment to the bottom left corner is 100 units. A. 517.5 square units B. 1,587 square units C. 3,174 square units D. 7,935 square units
Answer:
3,174
Step-by-step explanation:
Answer: 3,174
Step-by-step explanation:
115^2-69^2= sqrt8464=92
100+92=whole leg=192
192*69=13248= whole area
69*92=6348

when i multiply it by 6 and subtract 29, the answer is 37.
what is my number?
Let the required number be "x"
According to the statement:
x(6) - 29 = 37
6x - 29 = 37
6x = 37 + 29
6x = 66
x = 66/6
x = 11
Therefore, the required number is 11.
when i multiply it by 6 and subtract 29, the answer is 37.
what is my number?
SOLUTION:▶️Let the required number be x.
According to the question the equation will form like:
▶️6x - 29 = 37
▶️6x = 37+29 (transposing x to RHS)
▶️6x = 66
▶️x = 66/6 (transposing 6 to RHS)
▶️x = 11
VARIFICATION:According to the question :
▶(️11×6) - 29
▶️ 66 - 29
▶️37
Hence varified..

A drug is available in 100mg/mL. The patient needs 0,75 g of the drug. How many mL should be administered.
Answer:
7.5 ml
Step-by-step explanation:
A drug is available in 100mg/mL.
This means, there is
100mg of the drug in 1 ml
100mg = 1 ml
Step 1
We convert 100mg to g
1 mg = 0.001 g
100 mg = x
Hence,
x = 100 × 0.001g
x = 0.1 g
Hence,
We have 0.1g in 1 ml
Step 2
The patient needs 0.75 g of the drug. How many mL should be administered?
From step 1, we know that:
0.1g = 1 ml
0.75g = x
Cross Multiply
0.1g × x = 0.75g × 1 ml
x = 0.75g × 1 ml/0.1g
x = 7.5 ml
Therefore, 7.5 ml should be administered to the patient.

Answer:
height = 12 feet
Step-by-step explanation:
r (radius of circle) = 7 ft
pi = 3.14 (in this context)
v = 1/3 * [tex]πr^{2}[/tex] (or pi * radius squared) * h
r squared = 49 ft
v = 1/3 3.14 * 49 * h
v = 1/3 153.86 * h
3v = 153.86 * h
v = 196π
v = 615.44
3v = 1,846.32
1,846.32 = 153.86 * h
h = 12 ft.
A number between 10 and 20 is both a foctor of 60 and
a multiple of 6.
What is the number?
Answer:
12
Step-by-step explanation:
List out factors of 60 =
1 x 60 = 60
2 x 30 = 60
3 x 20 = 60
4 x 15 = 60
5 x 12 = 60
6 x 10 = 60
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60 are factors of 60.
List out multiples of 6 from 10 to 20.
12 and 18.
Since 12 is seen on one of the factors of 60 and a multiple of 6 between 10 and 20, the answer is 12.
In 2003 a gallon of gas cost $1.75. The cost has risen $0.17 each year since then
Write an equation to represent the cost of gas (in gallons) as a function of years.
What would the cost of a gallon of gas be in 16 years?
Answer:
x + m × y
$4.47
Step-by-step explanation:
The equation and computation is shown below:
Let us assume the cost of gallon be x
Increase each year be m
And, the number of years be y
So, the equation is
= x + m × y
The cost of gallon of gas in 16 years is
= $1.75 + $0.17 × 16
= $1.75 + $2.72
= $4.47

Answer:
x = 50
Step-by-step explanation:
The chord- chord angle is half the sum of the arcs intercepted by the angle and its vertical angle, that is
[tex]\frac{1}{2}[/tex](x + 110) = 80 ← multiply both sides by 2 to clear the fraction
x + 110 = 160 ( subtract 110 from both sides )
x = 50

Which is a better buy, 5 for $4.25 or 8 for $6.88?
Answer:
5 for $4.25
Step-by-step explanation:
First you find how much of one each cost
4.25 divided by 5 = 0.85
6.88 divided by 8 = 0.86
The one for 5 for $4.25 is one cent less
one cent is still money

Mai says that equations A and B have the same solution.
Equation A: –3(x + 7) = 24
Equation B:x + 7 = -8
Explain why this is true?
Answer:
Step-by-step explanation:
Equation A:
-3(x + 7) = 24
=> -3x -21 = 24
=> -3x = 45
=> x = -15
Equation B:
x + 7 = -8
=> x = -15
