Answer:
[tex]4\dfrac{3}{8}[/tex] cups of flour
Step-by-step explanation:
A muffin recipe, which yields 12 muffins, calls for 2/3 cup of milk for every 1 3/4 cups of flour.
Then this recipe, which yields one muffin, calls for
[tex]\dfrac{2}{3}:12=\dfrac{2}{3}\cdot \dfrac{1}{12}=\dfrac{1}{18}[/tex]
cup of milk for every
[tex]1\dfrac{3}{4}:12=\dfrac{7}{4}\cdot \dfrac{1}{12}=\dfrac{7}{48}[/tex]
cups of flour.
Thus,
this recipe, which yields a batch of 30 muffins, calls for
[tex]\dfrac{1}{18}\cdot 30=\dfrac{5}{3}=1\dfrac{2}{3}[/tex]
cups of milk for every
[tex]\dfrac{7}{48}\cdot 30=\dfrac{210}{48}=\dfrac{35}{8}=4\dfrac{3}{8}[/tex]
cups of flour.
Final answer:
To calculate the amount of flour needed to yield 30 muffins, we first find the amount of flour required for a single muffin and then scale it up to 30 by multiplying. For 30 muffins, approximately 1.094 cups of flour are required based on the original recipe ratios.
Explanation:
The question involves the use of ratios to calculate the amount of a particular ingredient required for a different quantity of the final product. Since the original recipe yields 12 muffins with 1 3/4 cups of flour, we first need to determine how much flour is needed for one muffin by dividing 1 3/4 cups by 12. After finding the flour quantity per muffin, we then multiply that by 30 to find out how much flour is needed for 30 muffins.
Step 1: Calculate the amount of flour for one muffin.
Amount of flour per muffin: 1 3/4 cups / 12 =
7/4 cups / 12 = 7/48 cups per muffin.
Step 2: Calculate the amount of flour needed for 30 muffins.
Amount of flour for 30 muffins: 7/48 cups per muffin x 30 = 7/48 x 30 =
52.5/48 or approximately 1.094 cups of flour.

When n basketball uniforms are purchased, the cost, C, of each uniform is given by the equation.
C = 40n + 260
If the total cost of the teams uniforms is $860, how many uniforms were purchased? What property of equality is the first step to use when solving this equation?
A.
Addition property of equality; n = 8
B.
Division property of equality; n = 6
C.
Multiplication property of equality; n = 13
D.
Subtraction property of equality; n = 15
Answer:
D. Subtraction property of equality; n = 15
Step-by-step explanation:
Given equation that shows the cost of n basketballs uniforms,
C = 40n + 260
According to the question,
Total cost = $ 860,
⇒ 40n + 260 = 860
Using subtraction property of equality, subtract 260 on both sides,
⇒ 40n = 860 - 260
⇒ 40n = 600
Using division property of equality, divide both sides by 40.
⇒ n = [tex]\frac{600}{40}[/tex] = 15.
Hence, 15 uniforms were purchased.
i.e. Option D is correct.

Find two consecutive positive integers whose product is 552.
Answer:
The numbers are 23 and 24
Step-by-step explanation:
Let
x ----> the first positive consecutive integer
x+1 ----> the second positive consecutive integer
we know that
The product of the two consecutive positive integers is 552
so
The algebraic expression that represent this situation is
[tex]x(x+1)=552[/tex]
Convert to expanded form
[tex]x^2+x-552=0[/tex]
Solve the quadratic equation by graphing
The roots of the equation are
[tex]x_1=-24[/tex] ----> the number cannot be negative
[tex]x_2=23[/tex]
see the attached figure
therefore
[tex]x=23\\x+1=24[/tex]
The numbers are 23 and 24
To find two consecutive positive integers whose product is 552, set up the equation x(x + 1) = 552, expand and solve the quadratic equation.
Explanation:To find two consecutive positive integers whose product is 552, we can set up the equation x(x + 1) = 552, where x represents the smaller integer.
Expanding the equation, we get x^2 + x - 552 = 0. This is a quadratic equation, and we can solve it by factoring or using the quadratic formula.
Factoring the quadratic equation, we find that (x - 23)(x + 24) = 0. So the two consecutive positive integers are 23 and 24.
Andrew’s math teacher entered the seventh-grade students in a math competition. There was an enrollment fee of $30 and also an $11 charge for each packet of 10 tests. The total cost was $151. How many tests were purchased?
use a tape diagram to solve and if-then statement
Answer:
p=11 packets were purchased
Step-by-step explanation:
30+11p=151
11p=121
then
121/11
so
p=11
Hope I understood the question :/
Answer:
Step-by-step explanation:
I believe the correct answer is that Andrew's Math Teacher purchased 11 packets of 10 tests each, meaning that the total number of test would be 110. I got this by subtracting the $30 entrance fee from the $151. After doing this we are left with $121. I then divided the $121 by the cost per packet and I was left with 11 packets. Since every packet contains 10 tests I multiplied that by the number of packets to get the final answer... 110 tests purchased.
Find an exponential function with a horizontal asymptote y = - 7 whose graph contains the points (0.- 6) and (1,6).
The exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6) is:
y = [tex]e^{(ln(13)x)} - 7[/tex].
To find an exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6), we can use the general form of an exponential function:
[tex]y = A * e^{(kx)} + C[/tex]
where A is the initial value, k is the growth/decay rate, e is the base of the natural logarithm (approximately 2.71828), x is the independent variable, and C is the y-coordinate of the horizontal asymptote.
Step 1: Determine the value of C (the y-coordinate of the horizontal asymptote):
Since the asymptote is y = -7, we set C = -7.
Step 2: Use the given points to find A and k:
For point (0, -6):
-6 = A * e⁰ - 7
-6 + 7 = A
A = 1
For point (1, 6):
6 = 1 * [tex]e^{(k*1)[/tex] - 7
13 = [tex]e^{k[/tex]
Step 3: Solve for k:
Take the natural logarithm of both sides: ln(13) = k
Step 4: Write the exponential function:
The exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6) is:
y = [tex]e^{(ln(13)x)} - 7[/tex].
This function will have a horizontal asymptote at y = -7 and pass through the given points (0, -6) and (1, 6).

Answer:
The values are x = 0° or x = 60°
Step-by-step explanation:
Given:
[tex]\cos x + \frac{1}{\sqrt{3} }\times \sin x = 1[/tex]
Let it be in the form of
[tex]a\cos x + b\sin x = 1[/tex] such that
a = 1
[tex]b=\frac{1}{\sqrt{3} }[/tex]
We have
[tex]\sqrt{(a^{2}+b^{2} )}=\sqrt{(1^{2}+(\frac{1}{\sqrt{3} }) ^{2} )}\\=\sqrt{\frac{4}{3}}\\=\frac{2}{\sqrt{3} }[/tex]
Now, Dividing both the side by [tex]\frac{2}{\sqrt{3} }[/tex] we get
[tex]\frac{\sqrt{3} }{2}\cos x + \frac{1}{2}\sin x =\frac{\sqrt{3} }{2}\\[/tex]
We Know
[tex]\sin 60 =\frac{\sqrt{3} }{2}\\and\\\cos 60 = \frac{1}{2}[/tex]
Now by replacing with above values we get
[tex]\sin 60\times \cos x + \cos 60\times \sin x = \frac{\sqrt{3} }{2}\\[/tex]
Also we have formula
[tex]\sin A\times \cos B + \cos A\times \sin B = \sin (A+B)[/tex]
By applying the above Formula we get
[tex]\sin (60+x)=\frac{\sqrt{3} }{2}\\[/tex]
Also ,
[tex]\sin (60)=\frac{\sqrt{3} }{2}\\and\\\sin (120)=\frac{\sqrt{3} }{2}[/tex]
Comparing we get
60 + x = 60 or 60 + x = 120
∴ x = 0° ∴ x = 120 - 60 = 60°
Therefore, the values are x = 0° or x = 60° i.e between 0° to 360°

Lora, a campaign manager, distributes flyers to 35% of the homes in her community. Lora distributes flyers to 630 homes. How many homes are in her community?
To calculate the total number of homes in Lora's community, the number of flyers distributed (630) is divided by the percentage of homes that received flyers (35%), resulting in a total of 1800 homes.
To find the total number of homes in Lora's community, we need to set up a proportion where the number of flyers delivered represents 35% of all homes. Since Lora distributed flyers to 630, that is 35% of the total homes. Using the percentage formula:
Total Homes = Distributed Flyers / Percentage of Homes
So, in this case, it would be:
Total Homes = 630 / 0.35
Dividing 630 homes by 0.35 (35% as a decimal) gives us:
Total Homes = 1800
Therefore, there are 1800 homes in Lora's community.

Final answer:
The slope of the line passing through (0, 5) and (-12, 2) is calculated using the slope formula and is found to be 1/4.
Explanation:
The slope of the line passing through the points (0, 5) and (-12, 2) can be calculated using the formula slope (m) = (rise)/(run), where 'rise' is the change in the y-values and 'run' is the change in the x-values. To find the slope, we subtract the y-value of the second point from the y-value of the first point and divide by the subtraction of the x-value of the second point from the x-value of the first point: m = (5 - 2) / (0 - (-12)) = 3 / 12 = 1/4. Therefore, the slope of the line is 1/4.

The cost of a babysitting on a cruise is 10 for the first hour, and 12 for each additional hour. If the total cost of baby Aaron was 58, how many hours was Aaron at the sitter?
Answer:
5 hours was Aaron at the sitter
Explanation:
Cost of baby sitting for the first hour: 10
Cost of baby sitting for additional hour= 12
Total cost of babysitting= 58
Since the cost of first hour is 10
Hence the remaining cost after first hour
= 54-10
=48
Which means 1 hour is consumed in the first hour
Now to calculate the remaining hours for every additional hour
= [tex]\frac{48}{12}[/tex]
=4 hours
Hence the total hour Aaron was with the sitter
= 1 hour + 4 hours

James has a bag 77 of nickels and dimes. The total value of coins is $6.60. How many dimes does James have?
James has 55 dimes in the bag
Step-by-step explanation:
The given is:
James has in a bag 77 of nickels and dimesThe total value of coins is $6.60We need to find how many dimes James has
Assume that the number of nickels is x and the number of
dimes is y in the bag
∵ There are x nickels in the bag
∵ There are y dimes in the bag
∵ There are 77 coins in the bag
∴ x + y = 77 ⇒ (1)
∵ 1 nickel = 5 cents
∴ The value of nickles in the bag = 5x cents
∵ 1 dime = 10 cents
∴ The value of dimes in the bag = 10y cents
∵ The total value of coins is $6.60
∵ 1 dollar = 100 cents
∴ $6.60 = 6.60 × 100 = 660 cents
∴ 5x + 10y = 660 ⇒ (2)
Now we have a system of equations to solve it
Multiply equation (1) by -10 to eliminate y
∵ -10x - 10y = -770 ⇒ (3)
- Add equations (2) and (3)
∴ -5x = -110
- Divide both sides by -5
∴ x = 22
Substitute the value of x in equation (2) to find y
∵ 22 + y = 77
- Subtract 22 from both sides
∴ y = 55
∴ The number of dimes is 55
James has 55 dimes in the bag
