If Brooke and her friend can bake 24 batches of brownies in 8 hours, and they both work 40 hours in one week, how many batches of brownies can they bake that week? If Brooke still charges $2.00 a batch, how much money will they make that week?
Answers
Answer:
Step-by-step explanation:
40hr(24b/8hr)=120b so they make 120 batches
120b($2/b)=$240 so they make $240 together (or $120 each)

Answer:
(i) The axis of symmetry is [tex]x = -4[/tex].
(ii) The axis of symmetry is [tex]x = 4[/tex].
(iii) The axis of symmetry is [tex]x = 1[/tex].
Step-by-step explanation:
We proceed to explain how we determine the expression for the axis of symmetry for each case:
(i) [tex]f(x) = 3\cdot (x+4)^{2}+1[/tex]
The expression depicts a vertical parabola, meaning that axis of symmetry is vertical, that is, a function of the form [tex]x = a,\,\forall\,a\in \mathbb{R}[/tex]. This line passes through the vertex of the parabola. The component [tex]x+4[/tex] contains the information of the horizontal component of the vertex, where the axis passes through. Therefore, the axis of symmetry is [tex]x = -4[/tex].
(ii) [tex]f(x) = 2\cdot x^{2} -16\cdot x +15[/tex]
At first we complete the square and factor the perfect square trinomial:
[tex]f(x) = 2\cdot \left(x^{2}-8\cdot x +\frac{15}{2} \right)[/tex]
[tex]f(x) = 2\cdot \left[(x^{2}-8\cdot x +16) +\frac{15}{2}-16 \right][/tex]
[tex]f(x) = 2\cdot (x-4)^{2}-17[/tex]
By applying the approach used in (i), we find that the axis of symmetry is [tex]x = 4[/tex].
(iii) First, we locate the vertex of the parabola, which is (1,-3). The first component of the ordered pair contains all the needed information to determine the equation of the axis of symmetry, which is [tex]x = 1[/tex].
In triangle XYZ right angled at Y. Find the length of the hypotenuse if the length of the other two sides is 1.6 cm and 6.3 cm.
Answers
Answer:
6.5 cm
Step-by-step explanation:
From Pythagoras theorem
C^2= a^2 + b^2
Where a, b are the sides of the triangle
C= hypotenus sides of the triangle
two sides are given as 1.6 cm and 6.3cm respectively.
C^2= 1.6^2 + 6.3^2
C^2= 2.56 + 39.69
C^2 = 42.25
C= √42.25
C=6.5 cm
Hence, the length of the hypotenuse is 6.5 cm

Ann gave Betty as many cents as Betty had. Betty then gave Ann as many cents as Ann then had. At this point, each had 12 cents. How much did Ann have at the beginning?
Answers
Answer:
Work backward. If at the end they both had 12 cents. Then Betty had to have given Ann 6 cents. Which means that Betty had to have had 18 cents, because there is always a total of 24 cents. Which meant that before that, Betty had 9 and was given 9 cents. So Betty originally had 9 cents. So Ann had 24 minus 9 or 15 cents at the beginning.

If your driving 60miles an hour and you drive for 1hour how far do you travel?
Answers
Answer:
60 miles
Step-by-step explanation:
1 hour=60 miles
1 hour=60 miles
The given information in this problem gives us: the speed of r = 60 mi/hr traveled over a distance of 1 mile. We need to find how much time, t, it took to travel a distance d of 1 mile at a speed r = 60 mi/hr, that is:
d/r = t or
t = d/r
Substituting the known values for d and r into the above equation, we have:
t = 1 mi./(60 mi/hr)
t = (1/60) hr.
t = (1/60) hr. (1)
t = (1/60) hr. (60 min./1 hr.)
t = (1/60)(60/1) min.
t = 1 minute ( or 60 seconds) to travel 1 mile at a speed of 60 miles per hour.

During a period of extreme cold, the average daily temperature dropped decreased by 112°F each day. How many days did it take for the temperature to decrease by 9°F? Which equation would you use to find the solution? I need help
Answers
Answer:
6 days
Step-by-step explanation:
Given
[tex]Rate = -1\frac{1}{2}^\circ F[/tex] -- Negative because it decreases
[tex]Final\ Temperature = -9^\circ F[/tex] -- Negative because it still decreases
Required
Determine the number of days
Let the number of days be d.
So:
[tex]Rate * d = Final[/tex]
[tex]-1\frac{1}{2} * d = -9[/tex]
[tex]1\frac{1}{2} * d = 9[/tex]
Convert to improper fraction
[tex]\frac{3}{2} * d = 9[/tex]
Make d the subject
[tex]d = \frac{9 * 2}{3}[/tex]
[tex]d = 3 * 2\\\\d = 6[/tex]

A map has a scale of 1/2 inch =75 miles.If two cities are 3 3/4 inches apart,how many miles apart are they really
Answers
Answer:
3 3/4 inches = 562.5 miles
Step-by-step explanation:
Given that,
1/2 inch = 75 miles
It means,
1 inch = (75×2) miles
= 150 miles
3 3/4 inches= 15/4 inches
So,
[tex]\dfrac{15}{4}\ \text{inches}=\dfrac{15}{4}\times 150\\\\=562.5\ \text{miles}[/tex]
Hence, 3 3/4 inches is equal to 562.5 miles.

A bakery sold a total of 200 cupcakes in a day, and 86% of them were mocha flavored. How many of the cupcakes sold that day were mocha flavored?
Answers
Answer:
172
Step-by-step explanation:
200 x 0.86 = 172
172 cupcakes sold were of mocha flavoured.
What is Percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a bakery sold a total of 200 cupcakes in a day, and 86% of them were mocha flavoured.
Let the number of mocha cupcakes sold are x,
Therefore, 86% of 200 = x
x = 200*86/100
x = 2*86
x = 172
Hence, the number of mocha cupcakes sold were 172.

If one tenement on the Lower East Side of New York had 101 adults and 91 children, and there was an average of 8 persons in a tenement apartment, how many apartments did this tenement have?
Answers
Answer:
24 Apartments
Step-by-step explanation:
To get the total amount of people living in the apartment building, you add 101 and 92.
101+91=192 total people
You then divide this total by the amount of people staying in each apartment, which is 8.
192/8=24 apartments
This leaves you with 24 apartments, with 8 people living in each one.
