Mike and Shawna are selling cookie dough for a school fundraiser. Customers can buy packages of chocolate chip cookie dough and packages of oatmeal cookie dough. Mike sold 12 packages of chocolate chip cookie dough and 3 packages of oatmeal cookie dough for a total of $225. Shawna sold 6 packages of chocolate chip cookie dough and 11 packages of oatmeal cookie dough for a total of $293. What is the cost each of one package of chocolate chip cookie dough and one package of oatmeal cookie dough?
Answer:
$19 for one package of oatmeal cookie dough and $14 for one package of chocolate chip cookie dough
Step-by-step explanation:
We need to set up two equations: one that shows how much money Mike made and one that shows how much money Shawna made.
Let's make a = price for one chocolate chip cookie dough and b = price for one oatmeal cookie dough.
First equation for Mike: 12a + 3b = 225
Second equation for Shawna: 6a + 11b = 293
Next we isolate b from Mike's equation: b = 75 - 4a
Then we plug this equation into Shawna's equation and we get:
6a + 11(75 - 4a) = 293
Solving for a would get us 14, or $14 for one chocolate chip cookie dough.
If we plug 14 = a into Mike's original equation and solve for b, we get b = 19, or $19 for one oatmeal cookie dough.

Find and simplify the expression
F(3x)=(3x)^2-3
____________________________
1.) Expand [tex]\bold{(3x)^2}[/tex]:[tex]3^2x^2-3[/tex]- We do this to make the problem easier to simplify. When expanded you can easily figure out what you need to find to make it a simplified equation.
2.) Calculate [tex]\bold{3^2}[/tex]:[tex]3^2=9[/tex]- We do this because it's the only thing we can find, that would make this a simplified problem.

If it costs £55 to buy 11 cushions, how much will it cost to buy 19?
Answer:
£95
Step-by-step explanation:
Cost of 11 cushions = £55
Unit cost of 1 cushion = 55/11 = £5 per cushion
Cost of buying 19 cushion = 19 × unit cost
= 19 × £5
= £95
Thus, it would cost £95 to buy 19 cushions
Step-by-step explanation:
11 cushions = £55
1 cushion = 55 ÷ 11
1 cushion = £5
19 cushions = £5 × 19
= £95

it is less than because it is shaded down, its less than or equal to because the line is solid.
Answer:
2y < - x - 4
Step-by-step explanation:
First find the equation of the line in the form y=mx+c (straight line)
The y-intercept is at -2 so c=-2.
For each 2 along the x-axis it goes 1 down the y-axis, so the gradient is -1/2, so m = -1/2
We now have y = -(1/2) x - 2
Try a coordinate, e.g. (0,0) one side of that line:
-(1/2) 0 - 2 = -2
-2 is less than 0, but we don't want (0,0) in the region, so we say
y < -(1/2)x - 2 or
2y < - x - 4
The Acculturation Rating Scale for Mexican Americans (ARSMA) is a psychological test that measures the degree to which Mexican Americans are adapted to Mexican/Spanish versus Anglo/English culture. The range of possible scores is 1.0 to 5.0, with higher scores showing more Anglo/English acculturation. The distribution of ARSMA scores in a population used to develop the test is approximately Normal with mean 3.0 and standard deviation 0.8. A researcher believes that Mexicans will have an average score near 1.7 and that first-generation Mexican Americans will average about 2.1 on the ARSMA scale.
What proportion of the population used to develop the test has scores below 1.7? Between 1.7 and 2.1?
Answer:
The proportion of the population used to develop the test that has scores below 1.7 is 0.063.
The proportion of the population used to develop the test that has scores between 1.7 and 2.1 is 0.0662.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The distribution of ARSMA scores in a population used to develop the test is approximately Normal with mean 3.0 and standard deviation 0.8.
This means that [tex]\mu = 3, \sigma = 0.8[/tex]
What proportion of the population used to develop the test has scores below 1.7?
This is the pvalue of Z when X = 1.7. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1.7 - 3}{0.8}[/tex]
[tex]Z = -1.63[/tex]
[tex]Z = -1.63[/tex] has a pvalue of 0.063
The proportion of the population used to develop the test that has scores below 1.7 is 0.063.
Between 1.7 and 2.1?
This is the pvalue of Z when X = 2.1 subtracted by the pvalue of Z when X = 1.7.
X = 2.1
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{2.1 - 3}{0.8}[/tex]
[tex]Z = -1.13[/tex]
[tex]Z = -1.13[/tex] has a pvalue of 0.1292
X = 1.7
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1.7 - 3}{0.8}[/tex]
[tex]Z = -1.63[/tex]
[tex]Z = -1.63[/tex] has a pvalue of 0.063
0.1292 - 0.063 = 0.0662
The proportion of the population used to develop the test that has scores between 1.7 and 2.1 is 0.0662.
• Work out the percentage change to 2 decimal places when £78.98 is increased to £100
Answer:
The total change is £21.02 from the original amount of £78.98. Therefore, the percentage change is directly related to the original amount.
Divide the total change by the original amount to determine the percentage change the new amount represents.
21.02÷78.98=0.15219 which rounds up to two decimal places as 15.22%.

Answer:
I dont know if you still need it but the area of the figure is 51.5 ft2.
The area of the given figure is equivalent to 39.5 square feet.
What is Area?Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -
V = ∫∫F(x, y) dx dy
Given is to find the area of the given figure as shown in the image.
We can write the area of the given figure as -
A{total} = A{Rectangle} + A{Δ1} + A{Δ2}
A{total} = (8 x 4) + (1/2 x 3 x 3) + (1/2 x 3 x 2)
A{total} = 32 + 4.5 + 3
A{total} = 39.5 square feet
Therefore, the area of the given figure is equivalent to 39.5 square feet.

Step-by-step explanation:
Given
Ratio of triangle sides
[tex]Ratio = 3 : 10 : 7[/tex]
Required:
The length of each side
Triangles in a triangle add up to 180.
The side with ratio 3 is:
[tex]S_1 = \frac{3}{3 + 10 + 7} *180[/tex]
[tex]S_1 = \frac{3 *180}{20}[/tex]
[tex]S_1 = \frac{540}{20}[/tex]
[tex]S_1 = 27[/tex]
The side with ratio 10 is:
[tex]S_2 = \frac{10}{3 + 10 + 7} *180[/tex]
[tex]S_2 = \frac{10 *180}{20}[/tex]
[tex]S_2 = \frac{1800}{20}[/tex]
[tex]S_2 = 90[/tex]
Lastly:
The side with 7 as its ratio
[tex]S_3 = \frac{7}{3 + 10 + 7} *180[/tex]
[tex]S_3 = \frac{7 *180}{20}[/tex]
[tex]S_3 = \frac{1260}{20}[/tex]
[tex]S_3 = 63[/tex]
Hence, the angles are: 27, 90 and 63

Perhaps you're expected to remember relevant trig identities.
tan(θ)^2 = sec(θ)^2 -1
cot(θ) = 1/tan(θ)

cot(θ) = 1/√(sec(θ)^2 -1)
cot(θ) = 1/√((25/24)^2 -1) = 24/√(25^2 -24^2) = 24/√49
cot(θ) = 24/7
