samantha needs to bake at least 120 pot pies to sell at her restaurant. she can bake 12 pot pies per hour and 15 veggie pot pies per hour.
write an inequality that represents the situation. let X be the number of hours she spends making chicken pot pies and y be the number of hours she spends making veggie pot pies.
Answer:
y>(line under >) - 4/5x + 8
Step-by-step explanation:
Phrase "at least" indicates that the total number of pies is greater than or equal to 120.
The number of chicken pot pies Samantha makes is 12x, and the number of veggie pot pies she makes is 15y.
Use this information to create the inequality:
12x + 15y >(line under >) 120
Simplify by solving for y to get this inequality:
y >(line under >) - 4/5x + 8

Help please thank you and also show the work please
Answer:
y= -1.4x-6.6
Step-by-step explanation:
(1,-8)
7x+5y=-7
Make the equation into standard form
Subtract 7x from both sides
5y=-7x-7
Divide all by 5
y=-1.4x-1.4
Since they are parrallel, we know the slope is -1.4x
y=-1.4x+b
(1,-8) is one of the points it goes through
Replace the x and y in the equation for the x and y in the incomplete equation
-8=-1.4+b
Add 1.4 to both sides
-6.6=b
Thus the equation is
y=-1.4x-6.6
Which statement correctly describes the decimal form of: 2/9
Answer:
0.222 (repeated)
Step-by-step explanation:
Fractions are essentially another way to write a division expression.
This means that if a/b, then it can also be written as a÷b. (a and b are variables)
So, 2/9 is the same thing as 2÷9.
You can then calculate 2÷9 using a calculator, long division, or any other way you usually solve questions involving division.
Find the values of X and Y
Don't have a clue on how to do this one.
Answer:
From the picture attached,
There are two parallel lines intersected by three transverse lines.
m∠2 = 98°, m∠3 = 23°, m∠8 = 70°
a). Since ∠1 and ∠2 are linear pairs,
=
m∠1 + m∠2 = 180°
m∠1 + 98° = 180°
m∠1 = 180 - 98
m∠1 = 82°
b). m∠4 = m∠7 [Corresponding angles]
m∠7 = 180° - (m∠2 + m∠3) [Property of a triangle]
= 180 - (98 + 23)
= 180 - 121
= 59°
m∠4 = m∠7 = 59°
c). m∠5 = 180° - (m∠3 + m∠4)
= 180° - (23° + 59°)
= 180° - 82°
= 98°
d). m∠6 = 180° - (m∠7 + m∠8)
= 180° - (59° + 70°)
= 180 - 129
= 51°
e). m∠7 = 59° [Calculated in part b]
f). m∠9 = 180° - (m∠4 + m∠8) [Property of a triangle]
= 180° - (59 + 70)°
= 180 - 129
= 51°
g). m∠10 = 180° - m∠9
= 180 - 51
= 129°
Cube root of x^3

x
Step-by-step explanation:
Cube root is basically [tex]\sqrt[3]{x}[/tex] and if you're looking for [tex]\sqrt[3]{x^{3} }[/tex] the 3's cancel out the radical so you get x. There's probably a better explanation online but I'm pretty sure it's x.
The sum of two numbers is -64. Their difference is -10. Find the numbers.
The smaller number is:
The larger number is:
Answer:
smaller: -37, larger: -27
Step-by-step explanation:
say one number is x the other one is y
x+y = -64
x-y = -10
subtract the two equations to get
2y = -54
y = -27
x = -37
-27 is larger, -37 is smaller
if - 2x + 4 = 8, will x be positive or negative? Without solving the equation, explain how you know.
X will be negative; in order to determine this for future problems move all like variables to the other side of the equation and see what you are left with. If you are left with -2x= some positive value then it must be a negative x to get a positive answer and vise versa.

what 198/28 as a mixed number?
Answer:
7 1/14
Step-by-step explanation:
198÷28 = 7.blablabla
Therefore, 7 is the integer
so you take 7 and multiply it by 28 = 196
198 - 196 = 2
Therefore, 2 is the remainder
The format for mixed numbers is Integer (remainder/denominator)
so the mixed fraction is 7 2/28
2/28 can be reduced to 1/14
Therefore the final answer is 7 1/14

Y varies directly as x, y = 35 when x = 5. Find y when x = 12
The value of y when (x = 12) is 84 and this can be determined by forming the linear equation with the help of the given data.
Given :
y varies directly as xy = 35 when x = 5The following steps can be used to determine the value of y when x = 12:
Step 1 - Given that y varies directly as x, that means:
[tex]\rm y \; \alpha \; x[/tex]
Step 2 - The above expression becomes:
y = kx ----- (1)
Step 3 - Given that y = 35 when x = 5, that implies:
35 = 5k
k = 7
Step 4 - Put the value of k in equation (1).
y = 7x
Step 5 - Now, the value of y when x = 12 is:
y = 7(12)
y = 84
So, the value of y when (x = 12) is 84.

A professor of statistics wants to test that the average amount of money a typical college student spends per day during spring break is over $70. Based upon previous research, the population standard deviation is estimated to be $17.32. The professor surveys 35 students and finds that the mean spending is $72.43. Which of the following statements is most accurate? Select one: a. reject the null hypothesis at ? = 0.01 b. reject the null hypothesis at ? = 0.10 c. fail to reject the null hypothesis at ? ? 0.10 d. reject the null hypothesis at ? = 0.05
Answer:
Option c: Fail to reject the null hypothesis at α = 0.10
Step-by-step explanation:
We are given;
Population mean; μ = 70
population standard deviation; σ = 17.32
Sample mean; x¯ = 72.43
Sample size; n = 35
Thus;
Null hypothesis; H0: μ = 70
Alternative hypothesis; Ha: μ > 70
Z-score formula is;
z = (x¯ - μ)/(σ/√n)
z = (72.43 - 70)/(17.32/√35)
z = 2.43/2.9276
z = 0.83
From online p-value from z-score calculator attached, using z = 0.83; significance level = 0.05 and one tailed hypothesis, we have;
P-value ≈ 0.2033
It's more than the significance value, so we will fail to reject the null hypothesis at α = 0.05
Similarly, From online p-value from z-score calculator attached, using z = 0.83; significance level = 0.01 and one tailed hypothesis, we have;
P-value ≈ 0.2033
It's more than the significance value, so we will fail to reject the null hypothesis at α = 0.01
Similarly, From online p-value from z-score calculator attached, using z = 0.83; significance level = 0.10 and one tailed hypothesis, we have;
P-value ≈ 0.2033
It's more than the significance value, so we will fail to reject the null hypothesis at α = 0.10
From the 3 significance values, the correct option is option c. fail to reject the null hypothesis at α = 0.10
Using the z-distribution, it is found that the most accurate statement is:
c. fail to reject the null hypothesis at [tex]\alpha = 0.1[/tex]At the null hypothesis, it is tested if the average spending is not over $70, that is:
[tex]H_0: \mu \leq 70[/tex]
At the alternative hypothesis, it is tested if it is over $70, that is:
[tex]H_1: \mu > 70[/tex].
We have the standard deviation for the population, hence, the z-distribution is used to solve this question.
The test statistic is given by:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean. [tex]\mu[/tex] is the value tested at the null hypothesis. [tex]\sigma[/tex] is the standard deviation of the sample. n is the sample size.In this problem, the values of the parameters are as follows: [tex]\overline{x} = 72.43, \mu = 70, \sigma = 17.32, n = 35[/tex].
Hence, the value of the test statistic is:
[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{72.43 - 70}{\frac{17.32}{\sqrt{35}}}[/tex]
[tex]z = 0.83[/tex]
Using a significance level of [tex]\alpha = 0.1[/tex], the critical value for the right-tailed test, as we are testing if the mean is greater than a value, is [tex]z^{\ast} = 1.28[/tex].
The lower the significance level, the higher the critical value.Since for a significance level of 0.1, [tex]z < z^{\ast}[/tex], we fail to reject the null hypothesis at [tex]\alpha = 0.1[/tex], and option c is correct.

There are 8 fewer than double the
number of students in the chorus than in
the band. There are 54 members in the
chorus. Which equation represents how
to find the number of students in the
band?
A. 2x - 8= 54
B. 2x + 8 = 54
C. 8x - 2 = 54
D. 8x + 2 = 54
Answer:
The equation to find the number of students in the
the band will be: 2x - 8= 54
Step-by-step explanation:
Let the number of members in the chorus = x
so the double number of members in the chorus will be = 2x
As Total members in the chorus = 54
As there are 8 fewer than double the number of students in the chorus than in the band. i.e. 2x - 8
Therefore, the equation to find the number of students in the
the band will be: 2x - 8= 54
