Step-by-step explanation:
Ethan is planting flowers in flower boxes. Each flower box can hold 4 flowers. Ethan will plant 25 red flowers and 13 white flowers in the flower boxes. Part A Write and solve an equation to find the fewest number of flower boxes Ethan will need to plant all the flowers. Show your work.
Answer:
The fewest amount of boxes would be 10
Step-by-step explanation:
I added the 25 red flowers to the 13 flowers and got 38. I then divided 38 by 4 getting 9.5. 9.5 isn't a full box so I rounded to the decimal and got 10.
I hope this what you were looking for.
Using a arithmetic operations , the fewest number of boxes Ethan will need to plant all the flowers ls 10
Creating a
Number of flowers per box = 4 flowersTotal number of flowers to be planted :
Number of red + Number of white flowersTotal number of flowers = 25 + 13 = 38 flowers
Number of flower boxes = (total number of Flowers ÷ number of flowers per box)
Number of flower boxes = (38 ÷ 4) = 9.5 flower boxes
Therefore, the fewest number of boxes that will be needed is 10.

4. An isosceles triangle has sides that measure 7cm and 15cm. Find the third side of the
triangle, then find the perimeter.
Answer:
Third side is 15cm. Perimeter is 37cm.
Step-by-step explanation:
In a triangle sum of two sides is always greater than third side. Two sides of a isosceles triangle are equal.
So if the third side is 7cm
7+7=14cm which is less than 15 cm.
hence third side is 15 cm as
15+15=30cm which is greater than 7cm
15+7=22cm which is greater than 12cm
then
perimeter=15+7+15=37cm

Answer:
If you have to do the sliders problem the answeres in order are, set a to -3, set b to 2 and keep c at 0.
Step-by-step explanation:
the correct answer is y=-3 sin(2x) and the equation from the sliders should match the answer.
y=-3 sin(2x) is the equation has a maximum at (0, –1) and a minimum at ( pi Over 3, negative 5)
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given,
We need to use the sliders to change the values of a, b, c, and d in the cosine function.
We need to find the equation which has maximum at (0, –1) and a minimum at (pi Over 3, negative 5)).
While doing slider problems we have to set the values as set a to -3, set b to 2 and keep c at 0.
y=-3 sin(2x) is the answer and the equation from the sliders should match the answer.
Hence y=-3 sin(2x) is the equation has a maximum at (0, –1) and a minimum at ( pi Over 3, negative 5)

PI
Answer:
D. pi
Step-by-step explanation:
Circumference of a circle = [tex] \pi d [/tex]
Diameter = d
Therefore, ratio of circumference of a circle to its diameter would be:
[tex] \pi d : d [/tex]
[tex] = \frac{\pi d}{d} = \pi [/tex] => (d cancels d)
Therefore, the ratio of the circumference of a circle to its diameter is [tex] \pi [/tex]

5% of items in a large batch of items produced at a local foundry' are defective. If 50 of these items are selected at random, what is the probability that exactly 2 of the items will be defective? Round to four decimal places.
Answer:
0.2611
Step-by-step explanation:
We have x to be binomially distributed random variable which denotes the items number that are defective
We have been given n = 59 as our sample size
Probability of 5% = probability of success
1-5% = 0.95
We solve using this formula
nCxP^xq^n-x
= 50C2(0.05)²(0.95)^50-2
= 0.2611
This is the probability that exactly 2 would be defective

A rectangular building with a square front is to be constructed of materials that costs 11 dollars per ft2 for the flat roof, 14 dollars per ft2 for the sides and the back, and 15 dollars per ft2 for the glass front. We will ignore the bottom of the building. If the volume of the building is 5,600 ft3, what dimensions will minimize the cost of materials? (Round your answers to the nearest hundreth such that the dimensions increase from the smallest to the largest.)
Answer:
y = 23.14 ft
x = 15.56 ft
so the dimensions of the building will be = 15.56 ft x 15.56 ft x 23.14 ft
Step-by-step explanation:
the area of the roof = xy
cost of the roof = 11xy
the area of the sides and back = 2xy + x²
cost of the sides and back = 14(2xy + x²) = 28xy + 14x²
area of the glass front = x²
cost of the glass front = 15x²
minimize:
total cost = 11xy + 28xy + 14x² + 15x² = 39xy + 29x²
total volume = x²y = 5600 ⇒ constraint
39y + 58x = 2λxy
39x = λx2
x²y = 5600
λx = 39 which we replace into the first equation
39y + 58x = 78y
58x = 39y
(58x)²y = 58² · 5600
now we replace 58x by 39y
(39y)²y = 58² · 5600
39² · y³ = 58² · 5600
y³ = (58² · 5600) / 39² = 12,385.53583
y = ∛12,385.53583 = 23.14 ft
x² = 5600/ 23.14 = 242.04
x = 15.56 ft
