Step-by-step explanation:
let's look at the full numbers under the square roots when bringing the external factors back in :
sqrt(9×9×2) - sqrt(3×3×7) + sqrt(8) - sqrt(28)
and let's present these numbers as the product of their basic prime factors
sqrt(3×3×3×3×2) - sqrt(3×3×7) + sqrt(2×2×2) - sqrt(2×2×7)
now we see that we have 2 pairs of square roots : 1 pair ends with a factor of 2, and one pair with a factor of 7.
let's combine these
sqrt (3×3×3×3×2) + sqrt(2×2×2) - sqrt(3×3×7) - sqrt (2×2×7)
and now we move the factors of 2 and 7 back out in front (of course, we need to apply the square root on these factors) :
9×sqrt(2) + 2×sqrt(2) - 3×sqrt(7) - 2×sqrt(7) =
= (9+2)×sqrt(2) - (3+2)×sqrt(7) = 11×sqrt(2) - 5×sqrt(7)
and that is the first answer option.

In triangle RST, mZR>m2S +mZT. Which must be true of triangle RST? Check all that apply.
OmZR > 90°
mZS + mZT< 90°
0 m2S = mZT
OmZR>mZT
OmZR>mZS
OmZS> mZT
Answer:
Step-by-step explanation:
1,2,4,5
The correct statements are,
m∠R > 90°
m∠S + m∠T < 90°
m∠R > m∠T
m∠R > m∠S
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Here, RST is a triangle,
Therefore,
m∠R + m∠S + m∠T = 180°
⇒ m∠S+m∠T = 180° - m∠R
Since, m∠R > m∠S + m∠T
⇒ - m∠R < - (m∠S + m∠T) (by multiplying-1 on both sides)
⇒ 180°- m∠R < 180° - (m∠S + m∠T) (by adding 180° on both sides)
⇒ m∠S+m∠T < 180° - (m∠S + m∠T)
⇒ m∠S+m∠T+ m∠S+m∠T < 180° ( by adding m∠S + m∠T on both sides)
⇒ 2(m∠S+m∠T) < 180°
⇒ m∠S+m∠T < 90°
⇒ m∠R > 90° ( because m∠R+m∠S+m∠T = 180° )
Again, m∠R > m∠S + m∠T
⇒ m∠R > m∠S and m∠R > m∠T
Thus, Option first second fourth and fifth are correct.
Since, m∠S = m∠T is only possible when m∠R=90° (but it is not given)
That is why m∠S = m∠T is not correct.
And, there are not enough information to prove m∠S > m∠T
That is why m∠S > m∠T is also incorrect.

(Please help I'm VERY lost)
A. 52%
B. 26%
C. 30%
D. 25%
Answer:
B. 26%
Let say a month=30days
✓if ½ a month is 15 days
Then 30 days = 2(1720)
= $3440.00
% = (900÷3400)x100 =26%
Simplify the following fraction:
90/20
Answer:
9/2 simplified
and 4 1/2 as a mixed number
Answer:
Fraction: 9/2
Mixed: 4 1/2
Step-by-step explanation:
We do this by first finding the greatest common factor of 90 and 20, which is 10.
Then, we divide both 90 and 20 by the greatest common factor to get the following simplified fraction:
9/2
Therefore, this equation is true:
90/20 = 9/2
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.
9/2 = 4 1/2

Which shape does our galaxy have?(1 point)
circular
spiral
irregular
elliptical
Answer: spiral
Step-by-step explanation:
The shape that our galaxy have is : Spiral, because "Spiral-Structure" provides the Milky-Way its name. option (b) is correct.
Our galaxy, the Milky-Way, is classified as a spiral galaxy. Spiral-Galaxies are characterized by their distinct spiral arms that radiate from a central bulge. These arms contain stars, gas, dust, and other celestial objects.
The Milky-Way's spiral arms are home to a significant portion of its stars and are formed due to the gravitational interactions between different parts of the galaxy. This spiral structure gives the Milky-Way its name and appearance when observed from certain angles.
Spiral galaxies are one of the most common types of galaxies in the universe, and they play a crucial role in our understanding of cosmic structures.
Therefore, the correct option is (b).

Hello AljakeVillena!

You pull horizontally on a 50-kg crate with a force of 450 n and the friction force on the crate is 250 n. the acceleration of the crate is ?
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Given,
mass of crate = 50 kgForce you pull it with = 450 NFrictional force = 250 NAcceleration = ?__________________
Let's first find the total force/net force acting on the crate. The total force will be :-
450 N - 250 N = 200 N.We subtracted the forces because both the forces act on opposite directions.
__________________
Now, let's find the acceleration of the crate. To find the acceleration we must divide the net force by the mass. So,..
Acceleration = Force/massa = F/ma = 200/50a = 4 m/s²__________________
So, the acceleration of the crate is 4 m/s².

Force is mass times acceleration for linear motion. The acceleration of the crate in considered situation is 4 N/kg
How to calculate the acceleration from mass and force given?If net force is applied on an object of mass "m" in linear direction, with magnitude F, then, acceleration of that object is:
[tex]a = \dfrac{\rm F}{\rm m} \: \rm[/tex]
(assuming one dimensional motion, force is also in that dimension).
Here, it is given that crate's mass m = 50kg
Force pulling the crate = 450 N (positive since it is in direction of motion (horizontal)
Force resisting the crate = -250 N (negative since it is opposite to the direction of motion).
Net force on crate = 450 N + (-250 N ) = 200N (positive, thus, in the direction of motion).
Acceleration of the crate = 200/50 = 4 N/kg
Thus, the acceleration of the crate in considered situation is 4 N/kg

C) 14 bags of chips and 5 jars of salsa
D) 18 bags of chips and 6 jars of salsa
Answer:
D) 18 bags of chips and 6 jars of salsa
Step-by-step explanation:
Given : The networking organization you joined is throwing a party. You are in charge of buying the chips, which cost $2.50 per bag and salsa, which costs $4 per jar. The chips & salsa budget you are given totals $60.
Inequality: [tex]2.5x+4y[/tex] ≤ [tex]60[/tex]
Solution :
x represents chips
y represents salsa
Option a: 10 bags of chips and 2 jars of salsa
so, x = 10 and y =2
Putting values in inequality
[tex]2.5(10)+4(2)[/tex] ≤[tex]60[/tex]
[tex]25+8[/tex] ≤[tex]60[/tex]
[tex]33[/tex]≤[tex]60[/tex]

[tex]50+8[/tex]≤[tex]60[/tex]
[tex]58[/tex]≤[tex]60[/tex]
Hence it is correct.
Option c : 14 bags of chips and 5 jars of salsa
so, x = 14 and y =5
Putting values in inequality
[tex]2.5(14)+4(5)[/tex]≤[tex]60[/tex]
[tex]35+20[/tex]≤[tex]60[/tex]
[tex]55[/tex]≤[tex]60[/tex]
Hence it is correct.
Option d :18 bags of chips and 6 jars of salsa

Find the equation of the circle in standard form given the center, point or radius. Show your solution.
Center (-3,5) & Point (-2,1)
Answer:
(x + 3)^2 + (y - 5)^2 = 17
Step-by-step explanation:
To find the radius: distance from point (-2,1) to the center from point (-3,5).
d = sqrt [(-2 - -3)^2 + (1 -5)^2]
d = sqrt [(-2 + 3)^2 + (1 -5)^2]
d = sqrt (1)^2 + (-4)^2 = sqrt 17
Radius = sqrt 17
Equation of the circle:
(x - h)^2 + (y - k)^2 = r^2
h = 3, k = 5, r = sqrt 17
(x - -3)^2 + (y - 5)^2 = (sqrt 17)^2
(x + 3)^2 + (y - 5)^2 = 17

the difference of complementary angles is 10 degree. find the measures of the angles.
Answer:
40° and 50°
Step-by-step explanation:
90=(x+10)+x
90=2x+10
80=2x
40=x
Therefore the answer is,
40 and 40+10
40° and 50°
Answer:
50° and 40°
Step-by-step explanation:
Complementary angles sum to 90°
let one angle be x then the other is x - 10
x + x - 10 = 90
2x - 10 = 90 ( add 10 to both sides )
2x = 100 ( divide both sides by 2 )
x = 50
x - 10 = 50 - 10 = 40
The angle measures are 50° and 40°

Amir is making pizza dough using a base recipe. For each cup of water, Amir needs to use 2 2/3
cups of flour. For each cup of flour he uses, Amir needs to use 1 1/2
tablespoons of olive oil. If he uses 4 cups of water, how many tablespoons of olive oil will he need?
4 cups of water would need 16 tablespoons of olive oil.
Each cup of water uses 2 2/3 cups of flour, while each cup of flour he uses, Amir needs to use 1 1/2 tablespoons of olive oil. Hence for 4 cups of water:
4 cups of water = 2 2/3 cups of flour × 4 cups = 32/3 cups of flour
32/3 cups of flour = 1 1/2 tablespoons of olive oil * 32/3 = 16 tablespoons of olive oil
4 cups of water would need 16 tablespoons of olive oil.

Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Step-by-step explanation:
For how to graph this, best to look at the guidelines for graphing a break-even formula.
What we do want to know is where these two values equal each other.
So, set: 400 + 0.20X = 800 + 0.10X
Subtract 400 from both sides; also subtract 0.10X from both sides, to get:
0.10X = 400
To solve for "X", divide out both sides by: 0.10, to get:
X = 4,000
What can can glean from this, is that:
(1) The sales person is better off accepting the higher base salary, up to the point of sales being no more than $4,000;
(2) The sales person is better off accepting the lower base salary, if their sales are normally expected to exceed $4,000.
