Which equation can be used to find the value of b if side a measures 8.7 cm? 8.7 + b = 54.6 17.4 + b = 54.6 26.1 + b = 54.6 34.8 + b = 5
Answers
because it is given that measure of side a is 8.7cm, in all other equations the values of a is different.
from the first equation we can find the value of b, that is
b = 54.6 - 8.7 = 45.9
so, value of b is 45.9cm

If a circle takes 8 rotations to roll 5 meters, what is its radius?
Answers
That means 8 times the circumference is 5 meters.
Let C = circumference.
8C = 5
C = 5/8 = 0.625
The circumference measures 0.625 m.
The circumference is
[tex] C = 2 \pi r[/tex]
Now we substitute our value into the circumference formula.
[tex]0.625 = 2 \pi r [/tex]
[tex]2 \pi r = 0.625 [/tex]
[tex]\pi r= 0.3125[/tex]
[tex]r = \dfrac{0.3125}{\pi} [/tex]
[tex]r \approx 0.09947 [/tex]
[tex]r \approx 0.1 ~m[/tex]
Find measure of angle d A. 122 degrees B. 61 degrees C. 238 degrees D. Not enough information
Answers
To find the measure of angle d, you can use the dot product formula and inverse cosine function.
Explanation:To find the measure of angle d, we need to consider the given information about vectors A and B. The vector A is represented as (122 cm, <145°) and the vector B is represented as (110 cm, <270°). The angle between two vectors can be found using the dot product formula: cos(theta) = A · B / (|A| * |B|). So, we can calculate the dot product and magnitude of vectors A and B, and then use the inverse cosine function to find the angle between them. The measure of angle d is __ degrees.

With a tail wind, a plane traveled 840 miles in 3hrs. With the same wind as a head wind, the return trip took 30 minutes longer. Find the plane's airspeed(in still air) and the wind speed....
So lost smh
Answers
Head Wind: 840 miles in 3.5 hours (i.e. Plane is going against the wind)
Let the plane speed (without wind) i.e. airspeed = v
Let the wind speed = w
The two equations can be made
1. v + w = 840 miles in 3 hours
v + w = 280 miles per hour
2. v - w = 840 miles in 3.5 hours
v - w = 240 miles per hour
This is a set of simultaneous equations. We can either solve with substitution or elimination. I choose elimination
v + w = 280
- (v - w = 240)
2w = 40
w = 20
So the wind speed, w, is 20 miles per hour
We can then substitute w = 20 into either equation to find v.
v + w = 280 miles per hour
v + 20 = 280
v = 260
So the planes airspeed, v, is 260 miles per hour
To find the plane's airspeed (in still air) and wind speed, we can use the concept of relative velocity. By setting up a system of equations using the distances and times for the outbound and return trips, we can solve for the values of the airspeed and wind speed. Solving these equations, we find that the plane's airspeed is 230 mph and the wind speed is 70 mph.
Explanation:To find the plane's airspeed and wind speed, we can use the concept of relative velocity. Let's assume the plane's airspeed (in still air) is P mph and the wind speed is W mph.
On the outbound trip, with a tailwind, the plane's groundspeed (the speed relative to the ground) will be the sum of its airspeed and the wind speed: P + W mph. Since the distance traveled is 840 miles and the time taken is 3 hours, we have the equation: Distance = Speed * Time, where Speed is the groundspeed. Therefore, we can write the equation as: 840 = (P + W) * 3.
On the return trip, with the same wind as a headwind, the plane's groundspeed will be the difference between its airspeed and the wind speed: P - W mph. As it took 30 minutes longer, the time taken will be 3 hours + 0.5 hours = 3.5 hours. Using the same equation, we have: 840 = (P - W) * 3.5.
Now we have a system of equations, which we can solve to find the values of P and W. Solving these equations, we get:
Airspeed (in still air) = 230 mph
Wind speed = 70 mph

What is the square root of 99 simplified?
Answers
Step-by-step explanation: To simplify the square root of 99, first create a factor tree that has 2 branches.
99 factors as 11 × 9 and 9 factors as 3 × 3.
Since we have a pair of 3's in our factor tree, a 3 can come out of the radical. Since we have a 11 that doesn't match up, it stays inside the radical and this gives us the answer of [tex]\sqrt[3]{11}[/tex].
I have also attached my work in the image provided.
The square root of 99, when simplified as much as possible, is approximately 9.94987437.
We have,
The square root of a number is a value that, when multiplied by itself, gives the original number.
In the case of the square root of 99, there is no whole number that can be multiplied by itself to result in 99.
Therefore, the square root of 99 is an irrational number.
To find an approximate value for the square root of 99, we can use a calculator or mathematical methods.
The square root of 99 is approximately 9.94987437.
This means that when we multiply 9.94987437 by itself, we get a value close to 99.
Since 9.94987437 cannot be simplified further as a whole number or a simplified radical, it is the most accurate representation of the square root of 99.
Thus,
The square root of 99, when simplified as much as possible, is approximately 9.94987437.

A pet store has 24 Tiger fish and 3 aquariums. Each aquarium has the same number of fish. How many tiger fish are in each aquarium?
Answers
24/3 = 8
Final answer:
To find the number of tiger fish per aquarium, divide the total number of fish (24) by the number of aquariums (3), resulting in 8 tiger fish per aquarium.
Explanation:
The question asks us to determine how many tiger fish are in each aquarium if a pet store has 24 tiger fish and 3 aquariums, with each aquarium having the same number of fish.
To find the answer, we need to divide the total number of tiger fish by the number of aquariums:
Total number of tiger fish = 24
Number of aquariums = 3
We calculate the number of fish per aquarium by performing the division 24 ÷ 3, which equals 8. Therefore, there are 8 tiger fish in each aquarium.

2. C. because the values go down then up
3. A. because the values go up consistently
Answer: (1) The correct option is B. (2) he correct option is (C). The correct option is (A).
Explanation:
(1)
In the graphs the x-axis represents the time and the y-axis represents the height.
From given figure 1 it is noticed that the height is consistently increases as the time increases but not in the same proportion.
Because the points are not lies on a single straight line, it means the height increases but not in the same rate.
Therefore, the correct option B.
(2)
From figure 2 it is noticed that at initial state the height decreases after that height increases.
The option 1 represent the increase at constant rate, option 2 represent the increase in height but not at constant rate and option 3 represents the fluctuation in height.
Therefore the correct option is C.
(3)
From figure 3 it is noticed that all the pints lies on a single straight line, therefore the height increases at a constant rate.
So, the correct option is A.

Answers
Hope this helps!~
Answer: Using operations with fractions, the diver's final location is:
- 60 3/4 meters relative to the surface of the water (60 3/4 meters below the surface of the water).
Solution:
Initial location: -50 1/4 meters
He descends another 10 1/2 meters: -10 1/2 meters
Final location = Initial location - 10 1/2 meters
Final location = - 50 1/4 meters - 10 1/2 meters
Final location = - (50+10) (1/4+1/2) meters
Final location = - 60 [(1)(1)+2(1)]/4 meters
Final location = - 60 (1+2)/4 meters
Final location = - 60 3/4 meters
