The perimeter of a rectangular field is 368 yards. If the width of the field is 87 yards, what is it’s length
Answer: The length of the rectangle would be 97 yards.
Step-by-step explanation:
87 multiplied by 2 would be 174.
Subtract 174 from 368 to get 194.
194 divided by two equals 97.
To check,
97 plus 97 equals 194.
87 plus 87 equals 174.
174 plus 194 equals 368, the perimeter.

What is the volume of a sphere with a radius of 4.5 inches?
Use 3.14 for .
Answer:
V≈381.7in³
Step-by-step explanation:
V=4/3πr³
=4/3•π•4.5³
≈381.70351in³
The volume of a sphere with a radius of 4.5 inches, calculated using the volume formula V = 4/3 * π * r^3, comes out to approximately 381.51 cubic inches.
Explanation:The volume of a sphere can be calculated using the formula for volume, V = 4/3 * π * r^3, where V denotes the volume, π is approximately 3.14, and r is the radius of the sphere. In this case, the radius (r) of the sphere is 4.5 inches. Plugging these values into our formula gives:
V = 4/3 * 3.14 * (4.5)^3
When you perform the calculations, you'll find the volume of the sphere to be approximately 381.51 cubic inches.

Briana is looking at the nutrition information on a bag of popcorn. According to the label, a single serving is 1/6 of the bag. How many servings are there in 4 bags?
Answer:
There are 2/3 of the content as servings in 4 bags
Step-by-step explanation:
In this question, we are asked to calculate the amount of servings in 4 bags
From the question, we can see that the amount of servings in a single bag is 1/6 of the bag.
Now the number of servings in 4 bags will be mathematically equal to ; 1/6 + 1/6 + 1/6 + 1/6 = 4 * 1/6 = 4/6 = 2/3
This means that in 4 bags, 2/3 of the total content is the servings

A bacterium in a petri dish multiplies by a factor of 31 every day. On day O,
there is 1 bacterium; on day 1, there are 31 bacteria; on day 2, there are
bacteria; on day 3, there are
bacteria, and so on.
What logarithmic equation can be used to find the number of days it takes for
a colony of 1 bacteria to develop?
Answer:
Step-by-step explanation:
Given that,
The bacterial increase a factor of 31 every day ,
Day 0 = 1 bacterium = 31^0
Day 1 = 31 bacterial = 31¹
Day 2 = 31× 31 bacterial = 31²
Day 3 = 31 × 31 × 31 bacterial = 31³
And so on,
Then, nth day will have
Day n = 31ⁿ bacterial
So, when will the bacterial be 1,000,000,000
Then,
31ⁿ = 1,000,000,000
Take the Natural logarithmic to base 31 of both sides
Log_31 (31)ⁿ = Log_31 (1,000,000,000)
n•Log_31 (31) = Log_31 (1,000,000,000)
Then, log_a (a) = 1
n = Log_31 (1,000,000,000)

Consider ΔABC, where ∠C = 90° and ∠A + ∠B = 90°. Click on the statements that are true about the relationships of the angles Angles A and B are complementary angles. If sin A ≈ 0.766, then sin B ≈ 0.766. If sin A ≈ 0.766, then cos B ≈ 0.766. If cos B ≈ 0.766, then the sin A ≈ 0.766,
Answer: Angles A and B are complementary angles
If Sin A ≈ 0.766 then Cos B ≈ 0.766.
If Cos B ≈ 0.766 then Sin A ≈ 0.766
Step-by-step explanation: In any given right angled triangle, one angle measures 90 degrees while the addition of the other two angles equals to 90 degrees. Hence if angle C is given as 90 degrees, then angles A and B added together equals 90 degrees (complementary angles equal 90 degrees).
Also, Sin A cannot be the same value as Sin B, since angle A and angle B are not equal in measurement. However, being complementary, the Sin of angle A equals the Cos of angle B.
If Sin A ≈ 0.766, then angle A ≈ 50 degrees
That makes angle B equal to 40 degrees. The Cos of B ≈ 0.766
Therefore if Sin A ≈ 0.766, then Cos B ≈ 0.766
If Cos B ≈ 0.766 then Sin A ≈ 0.766 are both correct
here is a right cone. what is the one shape of cross section we could create by slicing the cone parallel to its base
When a right cone is sliced parallel to its base, the resulting cross section is always a circle.
Explanation:If a cone is sliced parallel to its base, the shape that results is a circle. This is an aspect of conic sections, which are the curved shapes created when a plane intersects a cone. Other than circles, other possible shapes that we can obtain from slicing a cone include ellipses, parabolas, and hyperbolas, depending on the angles and location of the slice made. However, when the cut is parallel to the base, a circle is always formed. This is due to the consistent radius from the cone's axis to its slant height along the same parallel plane.

h(x) = -5x2 + 10x + 15
What is the height of the stone at the time it is thrown?
Answer:
The height of the stone at the time it is thrown is 15.
Step-by-step explanation:
You have a quadratic function of the form h (x) = ax² + bx + c. In this case it is h (x) = -5x²+10x+15, where a =-5, b =10, c =15, x is the time and h (x) is the height of the stone after being thrown.
The moment the stone is thrown is instant zero. So if x = 0, h (0) is calculated:
h(0)= -5*0² +10*0 +15
h(0)= 0 + 0 + 15
h(0)= 15
The height of the stone at the time it is thrown is 15.

With one mighty swipe of his sword, the knight cut off the flying dragon's head. If the dragon's head weighed 56.7 kg, how much force was used by the head to fall to the ground?
Answer:
The force used to fall by the head is
556.3N
Step-by-step explanation:
Given the the dragon's head has a mass m=56.7kg
Let us assume the acceleration due to gravity of the dragon's head is
9.81m/s^2
We know that the force
F=m*g
Substituting our data into the expression we have

Rewrite the function to determine whether it represents exponential growth or exponential decay. Identify the percent rate of change. Round numbers to the nearest hundredth, if necessary. y=(1.06)8t In the form y=a(1+r)t, the function is y≈ . To the nearest percent, the rate of change is a %.
Answer:
y ≈1*(1+0.59)^t. The rate of change is = 59%
Step-by-step explanation:
We have t mulitplied by 8 in the expression of y. We can write that power with a power of powers, using the property
[tex]a^{bc} = (a^b)^c = (a^c)^b[/tex]
Therefore,
[tex]a^{8t} = (a^8)^t[/tex]
If we replace a with 1.06, we obtain
[tex] y = 1.06^{8t} = (1.06^8)^t \approx 1.59^t = 1*(1+0.59)^t[/tex]
Thus, y ≈1*(1+0.59)^t. The rate of change is ln(1.59) * 1.59^t. After 1 unit of time t, the rate of change is 0.59*100 = 59%
The given function represents exponential growth with a rate of change of 6%. The function already fits the form y = a(1 + r)^t with a = 1 and r = 0.06.
Explanation:To rewrite the function y = (1.06)^8t in the form y = a(1 + r)^t, we can identify a as the initial amount and r as the rate of change. In this case, the initial amount a is implied to be 1 (since it is not explicitly multiplied by the base), and the base 1.06 represents the growth factor. Seeing as the base is greater than 1, this function represents exponential growth.
The percent rate of change can be found by subtracting 1 from the base and then converting it to a percentage. Therefore, the rate r is 1.06 - 1, which equals 0.06 or 6% when expressed as a percentage. Thus, the function in the requested form is y = (1 + 0.06)^8t, or simplifying the exponent, y = (1.06)^8t.
To the nearest percent, the rate of change is 6%.
7. It takes ounces of honey to make one apple pie. Betty baked 4 apple
pies. She also baked 4 pecan pies. Each pecan pie takes 4.4 ounces of
honey. How much honey did Betty use to bake the apple and pecan
pies?
ir
Answer:
17.6 ounces to make the pecan pies. I dont know how much honey she used to make the apple pie so if you could pls say I could edit the answer :)
Step-by-step explanation:
Betty used a total amount of honey equal to 4 times the ounces of honey needed for one apple pie plus 17.6 ounces of honey for the pecan pies. The exact total amount of honey used cannot be determined without knowing the amount of honey (x) used in an apple pie.
Explanation:The question is asking how much honey Betty used to bake apple and pecan pies. First we need to determine the amount of honey required per pie and then add the total amounts for each type of pie. Let's say it takes x ounces of honey to make one apple pie. Since Betty baked 4 apple pies, she would use 4x ounces of honey for the apple pies. For the pecan pies, each requires 4.4 ounces of honey, so for 4 pecan pies she would use 4 × 4.4 ounces which equals 17.6 ounces of honey.
To find the total honey used, add the honey used for apple pies and pecan pies: 4x + 17.6 ounces. Without the specific amount of honey for the apple pies (x), we cannot calculate the exact total amount of honey used.
