Answer:
B must travel at the rate of 10 miles per hour.
The speed at which B should travel is 10 mph
What is Speed?
Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the distance between A and B be D = 150 miles
Now , the equation will be
The speed of A = 20 mph
Let the speed of B be = B
The time required T = 5 hours
From the equation , Distance = Speed x Time
Substituting the values in the equation , we get
150 = ( A x T ) + ( B x T )
20 x 5 + ( B x 5 ) = 150
On simplifying the equation , we get
100 + 5B = 150
Subtracting 50 on both sides of the equation , we get
5B = 50
Divide by 5 on both sides of the equation , we get
B = 10 mph
Therefore , the value of B is 10 mph
Hence , the speed of B is 10 mph

Answer:
The value of x is 21.
Step-by-step explanation:
The angles of a triangle all add up to 180 degrees. One side has an angle of 90 (right angle). So to find the others you would subtract 180 from 90 and divide it by 2. And you will get 45, so both acute angles will be 45 degrees.
If you subsitute 21 for x you will get 2*21 + 3 = 45, which is true (42 + 3 = 45)

Answer:

Step-by-step explanation:
follow me say a thanks mark me branliest
I am very fast in answering questions
Answer:
33 degrees
Step-by-step explanation:
So the sum of a triangle's interior angles is 180. By adding 114 and 33, we know that the other two angles are 147 degrees. Then subtract 147 from 180 to find the single missing angle. 180 - 147 = 33.
x = 33 degrees.

Answer:
x = 60
Step-by-step explanation:
Answer:
x = 60°
Step-by-step explanation:
we know that triangles have 180 degrees so we can set up an equation:
86 + 34 + x = 180
now we subtract the sum of 86 and 34 from both sides to get a final answer:
x = 60
so lets plug our x value into the previous equation to check our answer:
86 + 34 + 60 = 180
when we add these numbers together, the equation checks out so we know our answer is correct.
hope this helps!

The correct option is A.
What is Exponential Growth?An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.
Given:
The population of a city is, 50000,
and growing 3% each year.
That means, the function that represents the situation is,
y = a(1+r)ˣ,
where a is the initial population and r is the rate in decimals and sx is the time period.
So,
y = 50000(1+0.03)²⁵
y = 104688.89
y ≈ 104689
Therefore, the population is, 104689.

Answer: 7/3
Step-by-step explanation:
To divide fractions, you can use the "keep, change, flip" method.
1. Keep the first fraction (7/9) as is.
2. Change the division sign to a multiplication sign.
3. Flip the second fraction (i.e. find the reciprocal). This means 1/3 changes to 3/1.
Rewrite the equation:
7/9 x 3/1
Multiply the numerators and the denominators together, respectively.

Find the area of the Compound shape
The answer is 333 cm^2
I just need the steps....
Answer:
333cm^2
Step-by-step explanation:
Divide the compound shape into the two separate parts, the rectangle and the triangle.
The rectangle measuring 18cm by 14cm, getting the area, use the formula length*width. This is 18*14= 252cm^2.
Then the triangle has the height, 9cm and base 18cm, finding the area use the formula, 1/2*base*height.
1/2*9*18= 81cm^2.
Add the two, 252+81= 333cm^2.
