Step-by-step explanation:
27*32=864
40%/100%=0.4
0.4*864=345.6
Identify the percent increase or decrease to the nearest percent.
from 25 to 86
Step-by-step explanation:
To find the percentage increase, we use the following formula:
percentage increase = (new value - old value) / old value * 100%
In this case, the old value is 25 and the new value is 86. So, we can plug these values into the formula:
percentage increase = (86 - 25) / 25 * 100% = 244%
Therefore, the percentage increase from 25 to 86 is approximately 244%.
Answer:
244% increase

-8x + 32 = -8 -16
Answer:
Step-by-step explanation:
-8x + 32 = -8 - 16
32 + 8 + 16 = 8x
4 + 1 + 2 = x
x = 7
Answer:
x=7
Step-by-step explanation:
-8x + 32 = -8 -16
First evaluate -8-16
-8x+32=-24<----
Subtract 32 on both sides
- 8x= - 56<----
divide by 8 on both sides

Christopher is choosing between two cell phone plans that offer the
same number of free minutes. T-Mobile's plan is $39.99 with additional
minutes costing $0.45 each. Verizon's plan is $44.99 with additional
minutes costing $0.40 each. Which equation will let you know how many
additional minutes, a, it will take for the two plans to cost the same? *
39.99a +0.45 = 44.99a + 0.40
39.99 a + 0.45 = 44.99a -0.40
39.99 +0.45a = 44.99 + 0.40a
39.99 + 0.45a = 44.99a +0.40
Answer:
39.99 + 0.45a = 44.99 + 0.40a you're welcome (:
Let g(x)=11x+6cos(x)−6tan(x). Find: dxdgsinx=?
The required value of \(dxdgsinx= cos(x) × (11 - 6sin(sin(x)) - 6 / cos²(sin(x))) ÷ (11 - 6sin(sin(x)) - 6sec²(sin(x)))\)is given by the above.
Given function: g(x)=11x+6cos(x)−6tan(x)
We are asked to find dxdgsinx
We can start by using the chain rule:
dy/dx=dydu×dudx
Let u = sin(x)So we can say that y = g(u) = 11u + 6cos(u) - 6tan(u)
Then dydu = 11 - 6sin(u) - 6sec²(u).
Using trigonometric identities: sec²(x) = 1 + tan²(x)
Therefore, sec²(u) = 1 + tan²(u) = 1 + sin²(u)cos²(u) / cos²(u) = (1 + sin²(u)) / cos²(u).
Plugging in the value of sin(u) and cos(u) from u = sin(x): sin(u) = sin(sin(x)) cos(u) = cos(sin(x))
Then we have:sec²(u) = (1 + sin²(sin(x))) / cos²(sin(x))
Now, we can substitute back:dydu = 11 - 6sin(sin(x)) - 6(1 + sin²(sin(x))) / cos²(sin(x))
Let's simplify this expression:dydu = 11 - 6sin(sin(x)) - 6cos²(sin(x)) / cos²(sin(x)) - 6sin²(sin(x)) / cos²(sin(x))dydu = 11 - 6sin(sin(x)) - 6 / cos²(sin(x))
Therefore, dxdgsinx = dxdu × dydx÷dydu
Now we just need to plug in the derivatives: dxdu = cos(x)dydx
= 11 - 6sin(sin(x)) - 6 / cos²(sin(x))dydu
= 11 - 6sin(u) - 6sec²(u)dydu
= 11 - 6sin(sin(x)) - 6 / cos²(sin(x))
Therefore: dxdgsinx = dxdu × dydx÷dydu= cos(x) × (11 - 6sin(sin(x)) - 6 / cos²(sin(x))) ÷ (11 - 6sin(sin(x)) - 6sec²(sin(x)))
Hence, the required value of dxdgsinx= cos(x) × (11 - 6sin(sin(x)) - 6 / cos²(sin(x))) ÷ (11 - 6sin(sin(x)) - 6sec²(sin(x))) is given by the above.

Answer:

Step-by-step explanation:
this is kind of tricky for me to answer,please help! I will make you Brainliest!
Answer:
Im not too sure because I haven't done this in a while but, I think the answer is 60cm, don't come at me if its wrong plssss
Step-by-step explanation:
if u divide it along the far left, closer to 12cm, u would have 2 rectangles. they would Both be close and If u added up 12cm and 12cm that would give you 24cm, and if you go to the other rectangle it would be 18 cm plus 18cm that would be 36cm. u do not multiply since it is perimeter and not area. Hope it helped!
Answer:
60 cm
Step-by-step explanation:
18+18+12+12
30+30
60
the 4 unknown sides we know that the 2 lengths equal 18 cm because both of them together are the same length as the base and the 2 widths add up to be 12 cm since it is the same size as the 12 cm width when added together if that makes sense

The area of the circle is 113.0 ft²
What is a circle?A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.
Given that, a circle with diameter 12 feet, we need to find its area,
Diameter = 2 × radius
Radius = 12/2
= 6 ft
Area of a circle = π × (radius)²
Area = 3.14 × 6²
= 3.14 × 36
= 113.04
Hence, the area of the circle is 113.0 ft²

leo ate 3/5 cup of strawberries and jack ate 7/10 cup of strawberries. how much more did jack eat than leo?
Jack ate 1/10 cup more strawberries than Leo
The problem states that Leo ate 3/5 cup of strawberries, and Jack ate 7/10 cup of strawberries. We need to find out how much more Jack ate than Leo.
To solve this problem, we first need to find a common denominator for the two fractions. The denominator is the bottom number of a fraction, which represents the total number of equal parts that make up a whole.
The smallest common denominator for 5 and 10 is 10. We can convert the fraction 3/5 into an equivalent fraction with a denominator of 10 by multiplying both the numerator and denominator by 2. This gives us 6/10.
Now, we have two fractions with the same denominator: 6/10 and 7/10. To find out how much more Jack ate than Leo, we can subtract the fraction representing what Leo ate from the fraction representing what Jack ate:
7/10 - 6/10 = 1/10
Therefore, Jack ate 1/10 cup more strawberries than Leo did.

The interval of the function f(x) = x^3 + x, is: (-∞, ∞).
For the function f(x) = x^3 + x, we need to find the intervals where it is increasing. To do this, we can find the first derivative of the function, which represents the slope at any given point: f'(x) = 3x^2 + 1
Next, we need to find when this derivative is greater than 0, as this indicates that the function is increasing: 3x^2 + 1 > 0
Since the left side of the inequality is a sum of squared terms, it will always be greater than 0. Therefore, the function is increasing for all values of x. The answer is: (-∞, ∞).

There are 624 elements in the sample space of the experiment in the board game.
The sample space in probability theory is the collection of all potential outcomes or findings of an experiment or random experiment.
The sample points, or likely ordered outcomes, are typically listed as elements in the set when a sample space is expressed in set notation.
A sample space is frequently referred to as S or U. A state space contains words, letters, numbers, symbols, and integers. They might also be countably infinite, uncountably infinite, or finite.
A really well, non-empty sample space is one of the three components of a probabilistic model.
The final two essential parts are an event space, which is frequently the power set of S if S is intermittent or a -algebra on S for S is continuous, and then a probability that is connected to each event probability measure function.

At the Beijing Olympics, Usain bolt won the 200 meter race with
a time of 19.30 seconds. (1m = 3.28ft, 1 mi = 2580ft)
a. What was his avg. speed in meters per second?
b. What was his avg. speed in mil
(A) Usain Bolt's average speed in meters per second was approximately 10.36 m/s.
(B) Usain Bolt's average speed in miles per hour was approximately 23.35 mph.
(A) Average speed = Distance / Time
Average speed = 200 meters / 19.30 seconds
Average speed = 10.36 meters per second
Therefore, Usain Bolt's average speed in meters per second was approximately 10.36 m/s.
(B) 1 mile = 2580 feet
Converting the distance from meters to miles:
Distance in miles = Distance in meters / (1 meter / 3.28 feet) / (1 mile / 5280 feet)
Distance in miles = 200 meters / 3.28 / 5280 miles
Time in hours = Time in seconds / (60 seconds / 1 minute) / (60 minutes / 1 hour)
Time in hours = 19.30 seconds / 60 / 60 hours
Average speed = Distance in miles / Time in hours
Average speed = (200 meters / 3.28 / 5280 miles) / (19.30 seconds / 60 / 60 hours)
Average speed = 23.35 miles per hour
Therefore, Usain Bolt's average speed in miles per hour was approximately 23.35 mph.
