In the spinner below the large wedges are twice the size of the smaller ones. What is true about the probability of landing on 6 and the probability of landing on 5?
Answer:
A
Step-by-step explanation:
If we take each small section to be "1" unit, we can say the large sections (for "2" and "5") are "2" units each. So in total there will be 8 sections.
Since 5 is "2" sections, we can say:
P(5) = 2/8 = 1/4
And 6 is "1" section, so we can say:
P(6) = 1/8
Definitely, Probability of landing a 6 is HALF that of probability of landing a 5. Also we can see this is the picture.
So, from the answer choices, A is right.

If cos theta = 3/5 and theta is in the first quadrant, what is sin 2 theta
Final answer:
To find sin 2θ when cos θ = 3/5, we first find sin θ using the Pythagorean identity and then apply the double angle formula, yielding sin 2θ = 24/25.
Explanation:
To find sin 2θ when given cos θ = 3/5 and θ is in the first quadrant, we can use the double angle formula for sine, which is sin 2θ = 2 sin θ cos θ. First, we need to find sin θ. Given that θ is in the first quadrant, all trigonometric functions are positive, and we can use the Pythagorean identity sin²θ + cos²θ = 1 to find sin θ. Since we know cos θ, cos²θ = (3/5)² = 9/25, which means sin²θ = 1 - 9/25 = 16/25. Taking the positive square root, since θ is in the first quadrant, sin θ = 4/5.
Now, we apply the double angle formula: sin 2θ = 2 × (4/5) × (3/5), which simplifies to sin 2θ = 24/25.

1/4 of a rod was painted red. 2/5 was painted orange and 2/7 of the remainder was painted yellow. The yellow section was 20cm long how long was the rod
Answer: 200cm long
Step-by-step explanation:
Let the length of the rod be x
red = 1/4 of the rod , which means 1/4 of x
orange = 2/5 of x
The remainder = x - ([tex]\frac{x}{4}[/tex] +[tex]\frac{2x}{5}[/tex])
= x - ([tex]\frac{13x}{20}[/tex])
= [tex]\frac{7x}{20}[/tex]
yellow = 2/7 of the remainder , that is
yellow = 2/7 of [tex]\frac{7x}{20}[/tex]
yellow = [tex]\frac{x}{10}[/tex]
and it was given that the yellow section was 20cm long , that is
[tex]\frac{x}{10}[/tex] = 20cm
x = 20 x10
x = 200
Therefore the rod was 200cm long
To determine the length of a rod based on fractions of it being painted different colors, with the yellow section known to be 20cm, we set up a proportion based on the fractions of the rod painted and use this to solve for the total length of the rod, which is 200cm.
Explanation:The subject of this question is Mathematics, and it is typically encountered at the Middle School level. To find the length of the entire rod when 1/4 is painted red, 2/5 is painted orange, and 2/7 of the remainder is painted yellow with the yellow section being 20cm, we need to set up an equation and solve for the total length of the rod.
First, we determine the fraction of the rod that remains after painting 1/4 red and 2/5 orange:
Calculate the total fraction painted already (red and orange combined): (1/4) + (2/5).Subtract that from 1 to find the remaining fraction.Of that remaining fraction, 2/7 is painted yellow.Since 2/7 of the remainder is 20cm, we can set up the proportion (2/7 of remainder) = 20cm to find the remainder.Once we find the remainder, we use it to calculate the full length of the rod.Let's start the calculations:
1. (1/4) + (2/5) = 5/20 + 8/20 = 13/20.
2. The remaining fraction = 1 - 13/20 = 7/20.
3. Let x be the total length of the rod. Since 2/7 of the remainder is 20cm, we can write the equation (2/7) * (7/20) * x = 20cm.
4. Simplify and solve for x:
(2/7) * (7/20) * x = 20cm,
(1/10) * x = 20cm,
x = 20cm * 10,
x = 200cm.
Therefore, the total length of the rod is 200cm.
Jiang purchased a moving truck for the business. He paid $40,000 for the truck. Its salvage value is $8,500. Select the correct answer from the drop-down menu.
The depreciation expense of the moving truck for a useful life of 10 years is (blank space). If the truck’s useful life where 15 years, the depreciation expense would come to(blank space).
Answer:
A. $3,150
B. $2,100
Step-by-step explanation:
A. Given,
Trucks cost price = $40,000
Salvage Value = $8,500
Useful life = 10 years
Since there is no requirement, I am using straight-line depreciation method to calculate the depreciation expense.
We Know,
Depreciation Expenses = (Cost price - Salvage Value) / Useful Life
Therefore,
Depreciation expense = ($40,000 - $8,500)/10
Depreciation Expense = $31,500/10
Depreciation Expense = $3,150
Therefore, under the straight-line method, the depreciation expense will be = $3,150.
B. Given, (When the useful year is 15)
Trucks cost price = $40,000
Salvage Value = $8,500
Useful life = 15 years
Since there is no requirement, I am using straight-line depreciation method to calculate the depreciation expense.
We Know,
Depreciation Expenses = (Cost price - Salvage Value) / Useful Life
Therefore,
Depreciation expense = ($40,000 - $8,500)/15
Depreciation Expense = $31,500/15
Depreciation Expense = $2,100
Therefore, under the straight-line method, the depreciation expense will be = $2,100

Erica and Amy started biking in the opposite directions at the same time from the same place. Erica biked at a speed of 6 meters per second and Amy biked at a speed of 4 meters per second. How soon were they exactly 1 km apart?
Answer:
100 seconds
Erica and Amy are at distance of 1 km in 100 seconds
Step-by-step explanation:
They both are travelling in opposite directions so the sum of the distances they travel is the distance between them.
Let's take t as the total time taken to achieve a seperation of 1km
Distance traveled by Erica , (Speed of Erica - v1)
x1 = v1 * t
Distance travelled by Amy , (Speed of Amy - v2)
x2 = v2*t
Therefore sum of the distances they traveled is x1+x2 = x
x = v1*t + v2*t
x = t*(v1 + v2)
Here it is given that final seperation between Amy and Erica is 1km or 1000 m
Therefore x = 1000 m
Thus t = [tex]\frac{x}{v1+v2}[/tex]
Substituting given values v1 = 6 m/s v2 = 4 m/s
Therefore,
They are apart by exactly 1km in a time of 100 sec
Willa is building birdhouses. Each side of the birdhouse will need 9 nails. How many nails does Willa need for each birdhouse? There are 7 sides on the birdhouse. If Willa uses only 7 nails on each side, how will the total number of nails she uses change?
The total number of nails will decrease by 14 nails when Willa will use 7 nails on each side.
Step-by-step explanation:
Sides of one birdhouse = 7
Nails used on each side = 9
Nails used on one birdhouse = Nails per side * Sides of birdhouse
Nails used on one birdhouse = 9*7 = 63 nails
If she uses 7 nails on each side, then the number of nails used on one birdhouse;
No. of nails = 7 * 7 = 49 nails
Change = Nails used on one birdhouse - No. of nails
Change = 63 - 49 = 14
The total number of nails will decrease by 14 nails when Willa will use 7 nails on each side.

Each birdhouse needs 63 nails. If Willa uses only 7 nails on each side, she will need a total of 49 nails.
Explanation:Each side of the birdhouse requires 9 nails, and there are 7 sides on the birdhouse. To find the total number of nails needed for each birdhouse, we can multiply the number of nails per side by the number of sides:
9 nails/side x 7 sides = 63 nails needed for each birdhouse.
If Willa only uses 7 nails on each side, the total number of nails she uses will change. The new total number of nails can be found by multiplying the new number of nails per side (7 nails) by the number of sides (7 sides):
7 nails/side x 7 sides = 49 nails in total.

if x varies directly as y, find x when y=8. x=11 when y=-3
Answer:
[tex]x=-\frac{88}{3}[/tex]
Step-by-step explanation:
When a quantity "A" varies DIRECTLY with another quantity "B", we can write the proportionality equation as:
A = kB
Where k is the proportionality constant (to be found)
In this problem, it is given x varies DIRECTLY with y, so we can write:
x = ky
Also, given, x = 11, y = -3, so we plug these into the equation and first find k:
x = ky
11 = k(-3)
k = -11/3
Now, we need to find x when y = 8, so we substitute and find x:
[tex]x=ky\\x=(-\frac{11}{3})(8)\\x=-\frac{88}{3}[/tex]
To find x for a given value of y when x varies directly as y, determine the constant of proportionality using the provided pair of values. Then use this constant to calculate x for the new value of y.
Explanation:Since x varies directly as y, we can write this as x = ky, where k is the constant of proportionality. To find the value of k, we use the given values: x=11 when y=-3. Substituting these values into the equation gives us 11 = k(-3), or k = -11/3.
To find x when y=8, we substitute y=8 and the value of k into the direct variation equation: x = (-11/3)(8) = -88/3 = -29.33. Therefore, x is approximately -29.33 when y=8.
What fraction of an hour is 8 minutes in simplest form
8 minutes is 2/15 of an hour when simplified, which is obtained by dividing both the numerator and denominator of the fraction 8/60 by the greatest common divisor of 8 and 60, which is 4.
To convert 8 minutes into a fraction of an hour, first understand that 1 hour is equivalent to 60 minutes. Therefore, to find what fraction 8 minutes is of an hour, you can create the ratio of 8 minutes to 60 minutes, which simplifies to:
8 minutes / 60 minutes = 8/60
This fraction can then be simplified by dividing both the numerator and the denominator by the greatest common divisor (GCD) of 8 and 60, which is 4, to obtain:
8/60 ÷ 4/4 = 2/15
Thus, 8 minutes is 2/15 of an hour in simplest form.
