Answer: The number is 106.4
Step-by-step explanation:
Let the number be x
Mar halves the number becomes = x x 1/2 to get 53.2
The equation to solve this problem is x/ 2 = 53.2
Such that to find x
x/2= 53.2
x = 2 x 53.2= 106.4
The number is 106.4
solve these..

The function g(t) = -16t2 + vt + h represents the height of an object, g, in feet above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet.
A model rocket is launched off the ground at an initial velocity of 80 feet per second.
Write a function that can be used to describe the flight of the model rocket.
A. g(t) = -16t^2 + 80
B. g(t) = -16t^2 + 80t
C. g(t) = -16t^2 + t + 80
D. g(t) = -16t^2 + 80t + 80
Answer:
B. g(t) = -16t² + 80tStep-by-step explanation:
Given function:
g(t) = -16t² + vt + hA model rocket is launched off the ground at an initial velocity of 80 feet per second.
This gives us
h = 0 and v = 80The function becomes:
g(t) = -16t² + 80tCorrect option is B.

Solve the system of equations
help me show the steps
5x -2y = 88
3x+4y=58
Answer:
x=18
Step-by-step explanation:
add 2y to both sides 5x=2y+88
subtract 88 from both sides 2y=5x-88
substitute 2y in the second equation for 5x-88
3x+10x-176=58
add like terms 13x-176=58
add 176 both sides
13x=234
x=18
Answer:
( 18, -6.5 )
Step-by-step explanation:
First choose which method you plan on using: Substitution or Elimation. I chose elimination based off preference.
How to solve using Elimination:
5x -2y = 88 (multiply every number in this equation by two)
3x+4y=58
10x -4y = 176
3x+4y=58 (combine these two equations)
13x = 234 (isolate x by dividing by 13 on both sides)
x = 18 (this is your value for x)
3(18) +4y=58 (plug in for x)
54+4y=28 (solve)
4y = -26 (subtract 54 from both sides)
y = -6.5 (this is y)
write answer in (x, y) format
( 18, -6.5 )

solve 15-(7x+20)=0.5(6x-14)
Answer:
x= 1/5
Step-by-step explanation:
Remove parentheses.
15−7x−20=0.5(6x−14)
Simplify 15-7x-2015−7x−20 to -7x-5−7x−5.
-7x-5=0.5(6x-14)
−7x−5=0.5(6x−14)
3 Expand.
-7x-5=3x-7
−7x−5=3x−7
4 Add 7x7x to both sides.
-5=3x-7+7x
−5=3x−7+7x
5 Simplify 3x-7+7x3x−7+7x to 10x-710x−7.
-5=10x-7
−5=10x−7
6 Add 77 to both sides.
-5+7=10x
−5+7=10x

If triangle ABC is similar to triangle EHG, find the measure of angle EHG.
First we need to find all the interior angles. So we know that the inside of a triangle (all the angles added up) equals 180. So we need to equal all the inside angles to 180.
2x + x + 60 = 180
Now lets start to solve. First let's subtract the 60 from both sides.
2x + x = 120
Now we need to add the x's together.
3x = 120
Now we must divide the 120 by 3 to get x by itself.
x = 40
Now just replace the x with 40 to find each of the sides. I'm guessing the triangles are reflecting each other so <EHG would be equal to 80.
ALSO to check if 40 would be correct, add all the angles together in the same triangle and they SHOULD add up to be 180! Which they do!
Step-by-step explanation:
Firstly let's calculate the unknown angles in triangle ABC
2x + x + 60° = 180° { being sum of angles of triangle }
3x = 180° - 60°
3x = 120°
x = 120° / 3
x = 40°
2x = 2 * 40° = 80°
Now since it is said that triangle ABC and triangle EHG are similar so
< EHG = < ABC = 2x = 80°
Hope it will help :)
What's 80% as a decimal?
Answer:
The ans is 0.8
Step-by-step explanation:
80% = 0.8 in decimal form.
Percent means 'per 100'. So, 80% means 80 per 100 or simply 80/100.
If you divide 80 by 100, you'll get 0.8 (a decimal number). Read more below on this webpage.
As you can see, to convert from percent to decimal just divide the percent value (80) by 100, and remove the "%" sign.

Answer:
16
Step-by-step explanation:
p is directly proportional to M
p = km
given that k is the constant of proportionality
128 = 8k
k = 128/8
k = 16
the equation thus is p = 16M

HELP PLEASE. The areas of the squares adjacent to two sides of a right angle are shown above. what is the area of the Square adjacent to the third side of the triangle?
Answer:
6.5units
Step-by-step explanation:
Find the length side of the smaller square
The area of the square is equal to
A = a^2
so
a^2 = 13
a = √13 units
step 2
Find the length side of the larger square
The area of the square is equal to
A = b^2
so
b^2 = 29.25
b = √29.25 units
step 3
Find the value of x
Applying the Pythagoras Theorem
x^2 = a^2 + b^2
x^2 = 13 + 29.25
x^2 = 42.25 units
x = √42.25
x = 6.5 units
The area of the square adjacent to the third side of the triangle is 85 square units.
Pythagoras theorem:Important information:
The area of Red square is 35 square unitsThe area of Green square is 50 square units.According to the Pythagoras theorem:
[tex]a^2=b^2+c^2[/tex]
Where, a is hypotenuse and b, c are two legs of a right-angle triangle.
Area of a square is the square of side length. So, [tex]b^2=35[/tex] and [tex]c^2=50[/tex]. Now,
[tex]a^2=35+50[/tex]
[tex]a^2=85[/tex]
Therefore, the area of the square adjacent to the third side of the triangle is 85 square units.

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(12, 3) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 12 × 3 = 36. In the next intermediate step , cancel by a common factor of 3 gives 3/
