the value of x + x(x^x) when x = 2.
solution:x + x(x^x)
by putting the value of x = 2 in the above expression we get:
2 + 2(2^2)
= 2 + 2(2 × 2)
= 2 + 2(4)
= 2 + 8
= 10
therefore, the value of x + x(x^x) when x = 2 is 10.
answer= option a
Answer is option a) = 10

Divide $3600 among Nancy Beverly and Todd in the ratio 2:3:4?
Answer:
nancy: $800, beverly: $1200, todd: $1600
Step-by-step explanation:
finding the portion of one part of the ratio:
3600 ÷ 9 = 400 (9 came from 2 + 3 + 4 in the ratio)
Nancy: 2 x 400 = $800
Beverly: 3 x 400 = $1200
Todd: 4 x 400 = $1600
checking the answer:
1600 + 1200 + 800 = 3600

Answer:
a.
Step-by-step explanation:
Probability that is a AB type blood given is a Male
P(AB/M) = 42/500 = 21/250
Probability that they are Male with an AB type blood out of all AB type blood people = Probability that is a Male out of all students
P(M∩AB) = P(M)
(42/105) = (500/1,250)
.4 = .4 ✅
The events "the student is male" and "the student has blood type AB" are independent events.
Carlos ran 3 1/2 miles on Saturday and
2 1/2 miles on Sunday. How many yards
did Carlos run in all? Show your work.
Answer:
6 yard
Step-by-step explanation:
Since, it given that:
Carlos ran 3 1/2 miles on Saturday and 2 1/2 miles on Sunday.
And asking for how many yards carlos run in all
in all = add
3 1/2 + 2 1/2
Add the whole number
3 + 2 = 5
Since they have the same denominator we can just add them
1/2 + 1/2 = 1 whole
Since it a whole we can add to the whole number
5 + 1 = 6
Thus, Carlos run 6 yards.
Lenvy
Answer:
6 yards
Step-by-step explanation:
To Find:
How many yards did Carlos run in all?
Solution:
In all means addition in this question
Thus,
3 1/2 and 2 1/2
3 1/2 + 2 1/2
we can turn them into improper fraction and then find the answer
3 1/2 = 7/2 and 2 1/2 = 5/2
7/2 + 5/2 = 12/2
12/2 = 6
Hence, Carlos run 6 yards in all

A water balloon is launched in the air from a height of 12 feet and reaches a maximum height of 37 feet after 1.25 seconds. Write an equation to represent the height h of the water balloon at time t seconds. Then, find the height of the balloon at 2 seconds.
The height of the balloon is given as h(t) = -16t² + 40t + 12 at 2 seconds, the height is 28 feet
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height of the water balloon after t minutes, hence:
h(t) = -16t² + vt + h₀
Where h₀ is the initial height = 12 feet and v is the initial velocity, hence:
h(t) = -16t² + vt + 12
The height of 37 feet after 1.25 seconds, hence:
37 = -16(1.25)² + v(1.25) + 12
v = 40 m/s
h(t) = -16t² + 40t + 12
After 2 seconds:
h(t) = -16(2)² + 40(2) + 12
h(2) = 28 feet
The height of the balloon at 2 seconds is 28 feet

Triangle ABC is a right triangle, and mC is 78°.
What is mA?
A. 2°
B. 12°
C. 22°
D. 32°
Answer:
[B] 12°
Step-by-step explanation:
Given:
Triangle ABC is a right triangle, and m∠ C is 78°.
Solution:
Knowing that Triangle = 180 degree
Square in a right angle = 90° angle.
Thus,
78+90 =168
180-168 is 12
Hence, the answer is [B] 12 degree

Jack went to baseball practice at 5:45 p.m. He returned home at 8:22 p.m. How long was he gone for? SHOW YOUR WORK PLEASE
Answer:
2 hours and 37 mins
Step-by-step explanation:
you want to get to a full hour so 5:45 closes hour would be 15 minutes later which would be 6:00 and then you add 2 hours which would be 8:00 and you have 22 minutes to get 822 p.m. so you add the minutes together 15 + 22 which you'll get 37 and you'll have the 2 hours on the side so it would be 2 hours and 37 minutes

A shape is made of 12 right triangles of equal size. Each right triangle has a base of 4cm and a height of 5cm. What is the total area, is square centimeters, of the shape?
Answer: 120 cm²
Step-by-step explanation:
Let's start by finding the area of one triangle
The formula for finding the area of a triangle is [tex]A=\frac{hb}{2}[/tex]
Where
A is the area
h is the height (5 for this)
and b is the base (4 for this)
Let's sub in our values and solve.
[tex]A=\frac{(5)(4)}{2}\\A=\frac{20}{2}\\A=10[/tex]
Since there are 12 triangles in the shape we must multiply our area for one triangle by 12 to find the total area of the shape
