A box contains orange balls and green balls. the number of green balls is 10 more than 2 times the number of orange balls. if there are 64 balls all together, then how many green balls and how many orange balls are there in the box
Answer:
52 green, 15 orange-Please mark brainliest hope this helped!
Step-by-step explanation:
g + o = 67 g = green, o = orange, x = total
g = 3o + 7
use substitution: (3o + 7) + o = 67
solve for o:
4o + 7 = 67
4o = 60
o = 60/4 = 15
solve for g:
g + 15 = 67
g = 52
A 108-inch pipe is cut into two pieces. One piece is five times the length of the other. Find the lengths of the two pieces.
The short piece is
inches long
Answer:
18 and 90
Step-by-step explanation:
If we express in units,
Long piece has 5 units
Short piece has 1 unit
total 6 units
108/6 = 18 inch
which is the length of 1 unit
short = 18 * 1
long = 18 *5

. A pilot is flying over a straight highway. He determines the angles of depression to two mileposts to be 32° and 56°, as shown in the figure. The pilot is flying at an altitude of 25,000 ft. Find the distance between point A and point B. Round your answer to the nearest thousandth. [32 56° A B
Answer:
Step-by-step explanation:
tan(90-32)=25000/B and tan(90-56)=25000/A
B=25000/(tan(58)) and A=25000/(tan(34))
B-A=25000/(tan58-tan34)=27003ft
The distance between point A and point B is 23195 ft.
What is the Angle of Depression ?For an object below the level, the angle created by the line of sight and the horizontal plane is called the Angle of Depression.
It is given that
A pilot is flying over a straight highway.
the angles of depression to two mileposts to be 32° and 56°, as shown in the figure
The pilot is flying at an altitude of 25,000 ft.
Tan [tex]\rm \theta[/tex] = Height / (Distance of the point and the plane horizontally )
Tan 32 = 25 /x
x = 25000 / tan 32
x = 40064 ft
tan 56 = 25/x
x = 25000/tan 56
x = 16869 ft

Solve for x
Answer:
x = 4, -7
Step-by-step explanation:
1) Factor out the common term 5.
[tex]5( {x}^{2} + 3x - 28) = 0[/tex]
2) Factor x² + 3x - 28.
[tex]5(x - 4)(x + 7) = 0[/tex]
3) Solve for x.
x = 4, -7
Therefor, the answer is x = 4, -7.
Answer:
x = 4, -7
Step-by-step explanation:
1. Solve the equation using the quadratic formula
The Quadratic formula provides the solution for [tex]Ax^{2} +Bx+C=0[/tex]
in which A, B, and C are numbers (or coefficients), as follows:
[tex]\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]
2. Determine the quadratic equation’s coefficients A, B, and C
The coefficients of our equation, [tex]5x^{2} +15x-140=0[/tex], are:
A = 5
B = 15
C = -140
3. Plug these coefficients into the quadratic formula
[tex]\frac{-b+\sqrt{b^{2}-4ac } }{2a}=\frac{-15+\sqrt{15^{2}-4x5x-140 } }{2x5}[/tex]
Calculate the expression inside the parentheses.
Simplify exponents and square roots.
[tex]\frac{-15+\sqrt{15^{2}-4x5x-140 } }{2x5}[/tex]
[tex]\frac{-15+\sqrt{225-4x5x-140 } }{2x5}[/tex]
Perform any multiplication or division, from left to right.
[tex]\frac{-15+\sqrt{225-20x-140 } }{2x5}[/tex]
[tex]\frac{-15+\sqrt{225-2800 } }{2x5}[/tex]
[tex]\frac{-15+\sqrt{3025} }{2x5}[/tex]
[tex]\frac{-15+\sqrt{3025} }{10}[/tex]
to get the result:
[tex]x=\frac{-15+\sqrt{3025} }{10}[/tex]
4. Simplify square root
Simplify 3025 by finding its prime factors.
3025

The prime factorization of 3025 is 5² • 11²
Write the prime factors.
[tex]\sqrt{3025}[/tex] = √5 • 5 • 11 • 11
Group the prime factors into pairs and rewrite in exponent form.
√5 • 5 • 11 • 11 = [tex]\sqrt{5^{2}x11^{2} }[/tex]
Use rule [tex]\sqrt{x^{2} }[/tex] = x to simplify futher.
[tex]\sqrt{5^{2}x11^{2}}[/tex] = 5 • 11
5 • 11 = 55
5. Solve the equation for x
x = [tex]\frac{-15+55}{10}[/tex]
The ± means two answers are possible:

What is the weight, in Newtons, of a person on Earth whose mass is 90 kilograms? Gravity near the Earth's surface is 9.8 m/s2.
What is the answer rounded to the nearest tenth?
Answer:
W = 882 N
Step-by-step explanation:
Given that,
The weight of a person, W = 90 kg
The value of acceleration due to gravity, g = 9.8 m/s²
We need to find the weight of the person on Earth. The formula for the weight of an object is given by :
W = mg
Substitute all the values,
W = 90 kg × 9.8 m/s²
W = 882 N
So, the weight of the person is equal to 882 N.

Help I don't understand this question at all
Answer:
(6)(5)(4) = 120
Step-by-step explanation:
For a permutation, order matters. The equation for a permutation is (n!) / (n-k)! where n represents the total number of items you have to choose from and k represents the amount of items taken into account. Therefore we have
6! / (6-3)! = 6!/3! =(6)(5)(4)(3)(2)(1)/(3)(2)(1) = (6)(5)(4) = 120
Here is another way to picture it:
In this case, we have 6 different dessert options to choose from. Let's say the desserts are A, B, C, D, E, and F
1st favorite (6 choices): A, B, C, D, E, and F. Let's say A is the 1st favorite
2nd favorite (5 choices): B, C, D, E, and F. Let's say B is the 2nd favorite
3rd favorite (4 choices): C, D, E, and F. Let's say C is the 3rd favorite
As you can see we actually have 6! choices for the numerator, but we are only choosing to 3 places, so we don't need the rest of the numbers, which can be represented by 3!
Therefore we have: 6! / (6-3)! = 6!/3! =(6)(5)(4)(3)(2)(1)/(3)(2)(1) = (6)(5)(4) = 120
