Duane recorded the temperature outside his window one morning. On the second day, the temperature went up 7 degrees. On the third day, the temperature went down 10 degrees. On the fourth day, the temperature went down 6 degrees, and it was 1°F. What was the temperature on the first day?
Answer:
The temperature on the first day was 10 °F.
Step-by-step explanation:
Let's find the temperature in every single step starting from the fourth day:
[tex]T_{4} = T_{3} - 6 F = 1 F[/tex]
[tex] T_{3} = 1 F + 6 F = 7 F [/tex]
Then, the temperature of the third day was 7 °F
On the third day:
[tex] T_{3} = T_{2} - 10 F = 7 F [/tex]
[tex] T_{2} = 7 F + 10 F = 17 F [/tex]
Hence, the temperature on the second day was 17 °F.
Now, on the second day:
[tex]T_{2} = T_{1} + 7 F = 17 F[/tex]
[tex] T_{1} = 17 F - 7 F = 10 F [/tex]
Therefore, the temperature on the first day was 10 °F.

Rebecca already knew 1 appetizer recipe before starting culinary school, and she will learn 3
new appetizer recipes during each week of school. After how many weeks of culinary school
will Rebecca know a total of 43 appetizer recipes?
Answer:
14 weeks
Step-by-step explanation:
so from what we know she already learned one appetizer recipe so she needs to learn 42 more so what we need to do since it's three every week we need to multiply three until we are able to get 42 so three times 14 gets 42 so that means that the answer would be 14

Here is a triangular prism 5 cm 1 What is the volume of the prism, in cubic centimeters? 2. What is the surface area of the prism in square centimeters? For your ans, just type the number.)
Answer:
Volume = 100cm³
surface area=
The volume of Triangular Prism is 120 [tex]cm^{3}[/tex] and the surface area of triangular prism is 184 [tex]cm^{2}[/tex]
What is triangular prism?A triangular prism is a 3D shape with two identical faces in the shape of a triangle connected by three rectangular faces. The rectangular faces are referred to as the lateral faces, while the triangular faces are called bases. The bases are also called the top and the bottom (faces) of the prism.
What is the volume of triangular prism?The volume of a triangular prism is the product of its triangular base area and the length of the prism.
Volume of Triangular Prism = ½ × b × h × l,
where b is the base length of the triangle, h is the height of the triangle, and l is the length of the prism.
What is the surface area of triangular prism?The surface area of a triangular prism is the area that is occupied by its surface. It is the sum of the areas of all the faces of the prism.
Surface area = (Perimeter of the base × Length) + (2 × Base Area)
According to the question
Length of the prism. = 10cm
Base length of the triangle = 6 cm
Height of the triangle = 4 cm
1> Volume of Triangular Prism = ½ × b × h × l
= ½ × 6 × 4 × 10
= 120 [tex]cm^{3}[/tex]
2> The surface area of triangular prismAs, Base area in Triangular Prism base is always triangular part
i.e Base area = 1/2 * 4 * 6
= 12 [tex]cm^{2}[/tex]
Perimeter of the base = 5 + 5 + 6
= 16 cm
Length of the prism = 10 cm
Surface area = (Perimeter of the base × Length) + (2 × Base Area)
substituting the value
Surface area = (16 * 10 ) + (2 * 12 )
= 184 [tex]cm^{2}[/tex]
Hence, The volume of Triangular Prism is 120 [tex]cm^{3}[/tex] and the surface area of triangular prism is 184 [tex]cm^{2}[/tex]

Maya and Edward cut lawns in the summer to earn spending money. Maya has a newer lawnmower, so Edward takes 15 minutes longer to cut a lawn than Maya. Working together they can both cut a lawn in 18 minutes. How long would it take Edward to cut a lawn alone?
Answer:
The answer would be 45 minutes.
Step-by-step explanation:
Just skipped to the answer on Edementum.
A fraction is a way to describe a part of a whole. The time it takes Edward to cut the lawn alone is 45 minutes.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Let the time taken by Maya to lawn the garden be x.
The rate at which Maya lawn = 1/x
Maya has a newer lawnmower, so Edward takes 15 minutes longer to cut a lawn than Maya. Therefore,
The rate at which Edward lawn = 1/(x+15)
Working together they can both cut a lawn in 18 minutes.
The rate at which they both work = 1/18
Now, the rate of working can be compared as,
1/x + 1/(x+15) = 1/18
(x+ x + 5)/x(x+15) = 1/18
(2x + 15)18 = x(x+15)
36x + 270=x² + 15x
x²-21x-270=0
x = 30, -9
Since time can not be negative. Therefore, the time it takes Edward to cut the lawn alone is,
x + 15
= 30 + 15
= 45 minutes
Hence, the time it takes Edward to cut the lawn alone is 45 minutes.

The amount of concrete, c, needed to make a walkway around a circular swimming pool varies directly as the square of the diameter, d, of the
pool. Which statement is true?
OA If the diameter of the pool is doubled, the amount of concrete needed is multiplied by 2.
•B. If the diameter of the pool is doubled, the amount of concrete needed is multiplied by 4.
OC. If the diameter of the pool is halved, the amount of concrete needed is multiplied by 2.
OD. If the diameter of the pool is halved, the amount of concrete needed is multiplied by 4.
Answer:
Step-by-step explanation:
For all Plato users
The amount of concrete needed after doubling the diameter of the circle will be multiplied by 4 by the initial amount. Hence, the correct option is (B).
What are direct proportions?Direct proportions are the proportions where a variable changes with another variable by direct mean so the coefficient of constant will be direct.
For example y ∝ x² here y varies with respect to x square.
y = Kx² where k will be the coefficient of constant.
Given that amount is Amount ∝ d²
Amount = k d²
By doubling the diameter
Amount = k (2d)²
Amount = 4 kd²
Amount = 4 × initial amount hence, the amount will be multiplied by 4.

The box plot for the given data set.
Solution:
The data values are
4, 5, 7, 7, 7, 8, 10, 11, 11, 13, 13, 14
Divide these values in two equal parts.
(4, 5, 7, 7, 7, 8), (10, 11, 11, 13, 13, 14)
Divide each group again in two equal parts.

C.B. Clothing ordered sweaters at a wholesale cost of $20 each. The store marked up the price 50 percent above the wholesale cost to use as their selling price. After every month that the sweater didn't sell, the store reduced the selling price by 20 percent. After how many monthly price reductions did the price dip below the wholesale cost? after 1 monthly price reduction after 2 monthly price reductions after 3 monthly price reductions after 4 monthly price reductions
Answer: after 2 monthly price reductions
Step-by-step explanation:
Given that :
Wholesale cost = $20 each
Markup = 50%
Selling price = $20 + (50% * 20) = $30
After each month selling price reduces by 20%;
Dip in price per month for which item didn't sell ;
Let m = Number of months
$30 - 0.2(30)m = $30 - 6m
After how many monthly price reductions did the price dip below the wholesale cost?
$30 - 6m < $20
-6m < $20 - $30
-6m < - $10
m > 10/6
m > 1.667
m = 2

The intensity,I, of light received at a source varies inversely as the square of the distance, d, from the source. If the light intensity is 33 foot-candles at 20 feet, find the light intensity at 5fee
Answer:
The light intensity is 528 foot-candles at 5 feet
Step-by-step explanation:
If x and y are in inverse variation, then x y = k, where k is the constant of variation
In the given question
∵ The intensity I, of light received at a source, varies inversely as the
square of the distance d, from the source
→ That means I × d² = k, where k is the constant of variation
∴ I × d² = k
∵ I = 33 foot-candle at d = 20 feet
→ Substitute them in the rule above to find k
∴ 33 × (20)² = k
∴ 33 × 400 = k
∴ 13200 = k
→ Substitute the value of k in the equation
∴ I × d² = 13200 ⇒ equation of variation
∵ d = 5
→ Substitute it in the equation to find I
∵ I × (5)² = 13200
∴ I × 25 = 13200
→ Divide both sides by 15
∴ I = 528
∴ The light intensity is 528 at 5 feet
