Anne has 5 pints of milk and is planning to make 6 cakes to sell in fundraising. Each cake will require 112 cups of milk. Does she have enough milk to make the 6 cakes? If so, how many cups of milk will be left, and if not, how many extra cups of milk would she need?
Yes she has enough milk; She will have 1 extra cup of milk.
No she does not have enough milk; She will need 1 more cup of milk.
Yes she has enough milk; She will have 112 extra cups of milk.
No she does not have enough milk; She will need 412 extra cups of milk.
Answer:
Option (1)
Step-by-step explanation:
Each cake requires cups of milk = [tex]1\frac{1}{2}[/tex] cups ≈ 1.5 cups
6 cakes will require milk = 6 × 1.5
= 9 cups
Anne has milk = 5 pints
∵ 1 pint = 2 cups
∴ 5 pints = 10 cups
Therefore, Anne has milk = 10 cups
Extra amount of milk Anne has = 10 - 9 = 1 cup
Hence, Answer is yes, she has enough milk. She will have 1 extra cup of milk.
Option 1 will be the answer.

Answer:
The answer required in ratio is: b:c = 9:8
Step-by-step explanation:
We are given:
The ratio a:b = 2:3 and the ratio a:c = 3:4
We need to find the ratio b:c
a:b=2:3 can be written as:
[tex]\frac{a}{b}=\frac{2}{3}[/tex]
Finding value of a by cross multiplying:
[tex]\frac{a}{b}=\frac{2}{3}\\3a=2b\\a=\frac{2b}{3}[/tex]
a:c = 3:4 can be written as: [tex]\frac{a}{c}=\frac{3}{4}[/tex]
Putting value of a and finding b:c
[tex]\frac{a}{c}=\frac{3}{4}\\Put\:a=\frac{2b}{3}\\\frac{2b}{3}}\times \frac{1}{c}=\frac{3}{4} \\Finding\:value\:of\:b/c\\\frac{b}{c}=\frac{3\times 3}{4 \times 2}\\ \frac{b}{c}=\frac{9}{8}[/tex]
So, we get the value of [tex]\frac{b}{c}=\frac{9}{8}[/tex]
The answer required is in ratio so: b:c = 9:8

it takes 10.4 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 9 students and observed that they had a mean of 10.7 hours with a variance of 1.44. A level of significance of 0.1 will be used to determine if the technique performs differently than the traditional method. Assume the population distribution is approximately normal. Find the value of the test statistic. Round your answer to three decimal places.
Answer:
Test statistic (t) = 0.625
Step-by-step explanation:
Step(i):-
mean of the Population(μ) = 10.4 hours
Sample mean (x⁻) = 10.7 hours
Standard deviation of the sample( S) = 1.44
The level of significance (α= 0.1
Sample size 'n' = 9
Degrees of freedom = n-1 = 9-1 =8
Step(ii):-
Test statistic
[tex]t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }[/tex]
[tex]t = \frac{10.7 -10.4}{\frac{1.44}{\sqrt{9} } } =0.625[/tex]

A house that is 30 feet tall casts a shadow that is 50 feet long. A nearby tree casts a shadow that is 75 feet long. HOW LONG IS THE TREE?
Answer:
the tree would be 45 feet tall
Step-by-step explanation:
so the house is 30 feet and 50 feet shadow, if you divide by 2 you can see that every 15 feet gives a 25 foot shadow, since 75-50 is 25 so in turn if the tree is 45 feet tall, it will make 75 foot shadow

Lydia has drawn quadrilateral ABCD with diagonal AC . According to her measurements, m∠DAC=m∠BCA and m∠DCA=m∠BAC . Without taking additional measurements, Lydia claims △ABC≅△CDA according to the ASA triangle congruence criteria. Explain why Lydia is correct.
Answer:
Lydia is correct because the ASA criterion for triangle congruence states that if two triangles have two pairs of congruent angles and the common side of the angles in one triangle is congruent to the corresponding side in the other triangle, then the triangles are congruent which would prove her statement correct.

The angle between the generator and the central axis of a double-napped cone is 40°. A plane intersects the central axis at an angle between 40° and 90°. Which conic section is formed?
Answer:
Ellipse
Step-by-step explanation:
From the given information:
Suppose the plane cuts the cone in such a manner that the plane is neither perpendicular nor parallel to the axis and also the angle of intersection is greater than the generator angle.
Then the conic section formed is an Ellipse.
The Conic Section that is formed from the intersection of the central axis at an angle between 40° and 90° will be An Ellipse.
How to transform a Plane?Let us consider that the plane cuts the cone in such a manner that the plane is neither perpendicular nor parallel to the axis and also the angle of intersection is greater than the generator angle.
Thus, we can say that when the plane intersects the double-napped cone in such a manner that the angle between the vertex and the angle is greater than the vertex angle.
Then the resulting conic section formed is an Ellipse.

Find rhe equation of the graphed line.
a. y = -x -6
b. y = x + 6
c. y = x - 6
d. y = -x + 6
Answer:
c. y = x - 6
Step-by-step explanation:
This question wants you to find the equation in slope-intercept form, each is y=mx+b, where m is the slope and b is the y-intercept. The first thing to do is find the y-intercept, to do this find the value of y when x equals zero. The way to do this is to look the value of y on the y-axis. In this case, the y-intercept is -6. Then, find the slope; since you are given the graph you can count out the slope. To do this find out how much the y and x values change. On this graph, y increases 1 when x increases 1, so the slope is 1/1 or one 1. So the equation is y=1x-6, which simplifies to y=x-6.
Noah and Lin are each trying to solve the equation x^2-6x+10=0.They know that the solutions to x^2=-1 are i and -i but they are not sure how to use this information to solve for x in their equation.Lin knows 36-40 is a negative number and isn’t sure what to do next. Show how Lin can write her solution using i.
Lin's work:
Answer:
x=3+i or x=3-i
Step-by-step explanation:
x²-6x+10=0
(x²-6x+9) + 1 = 0
(x-3)² + 1 = 0
(x-3)² = -1
x-3 = ± √-1 = ± i
x = 3 + i or x = 3 - i
The next step is that L in can write her solution using i be like x = 3 + i or x = 3 - i.
What is an equation?Mathematical phrases with two algebraic symbols on either end of the equal (=) sign are called equations. To illustrate this connection, the expressions just on the left and right are demonstrated to be equivalent to each other. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
From the given values provided in the question,
x² - 6x + 10 = 0
(x² - 6x + 9) + 1 = 0
(x - 3)² + 1 = 0
(x - 3)² = -1
x - 3 = ±√-1
x - 3 = ± i
x = 3 + i or,
x = 3 - i

If we assume the average number of teeth lost in the 5-9 group is 7 teeth and the average number of teeth lost in the 10 group is 12 teeth, what is the best estimate of the average (mean) and variance number of teeth lost per year
Answer:
Average = 7.83
Variance = 20.8339
Step-by-step explanation:
Since the average number of teeth lost in years 5-9 was 7 teeth this means that the average was 7 each year. Therefore, to estimate the average of teeth lost per year including all the years then we need to add the average each year and divide by the number of years being included like so...
7 + 7 + 7 + 7 + 7 + 12 = 47 teeth
47 teeth / 6 days = 7.83
Now that we have the mean we can find the variance.
[tex](7-7.83)^{2}[/tex] = 0.6889
[tex](12 - 7.83)^{2}[/tex] = 17.3889
0.6889 + 0.6889 + 0.6889 + 0.6889 + 0.6889 + 17.3889 = 20.8339
