A. 61 cubic feet
B. 320 cubic feet
C. 500 cubic feet
D. 1440 cubic feet
E. 8000 cubic feet
PLS HELP
Answer:
8000 cubic feet
Step-by-step explanation:
Volume of the pool = Length * Width * height
Given
Length =16ft
Width = 25ft
Height = 20ft
Substituting into the formula
Volume = 16 * 25 * 20
Volume of the pool = 8000 cubic feet
The Thompson Family has a garden in their backyard. They take the produce each week to a local farmers market. Use the graph to answer question. What percent of the garden is tomatoes? Show work for full credit.
Answer: 20%
Step-by-step explanation:
The total # of plants is 30, so what you do is take the # of tomatoes over 30. (6/30) and then x/100 so the formula would be 6/30=x/100. Then you would cross multiply and solve! so your answer is 20%

Solve this system of linear equations. Separate
the x- and y-values with a comma.
10x + 17y = -89
5x + 7y = -34
Answer:
(3,-7)
Step-by-step explanation:
10x +17y = -89
-(10x + 14y = - 68)
3y = -21
y = -7
5x + 7(-7) = -34
5x -49 = -34
5x = 15
x = 3
solving by elimination
7x-y=19
2x-3y=19
Answer:
2x + y = -2, x + 2y = 2
4x + y - 2z = 0, 2x+ 3z = 9 , -6x - 2y + z = 0
x + y = 4 , x - y = 2
Step-by-step explanation:
Answer:
x=2 and y=−5
Step-by-step explanation:
Let's solve your system by elimination.
7x−y=19;2x−3y=19
Multiply the first equation by -3,and multiply the second equation by 1.
−3(7x−y=19)
1(2x−3y=19)
Becomes:
−21x+3y=−57
2x−3y=19
Add these equations to eliminate y:
−19x=−38
Then solve−19x=−38for x:
−19x=−38
(Divide both sides by -19)
x=2
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
7x−y=19
Substitute2forxin7x−y=19:
(7)(2)−y=19
−y+14=19(Simplify both sides of the equation)
−y+14+−14=19+−14(Add -14 to both sides)
−y=5
y=-5
Work out the area of this circle.
Give your answer in terms of it and state its units.
14 cm
Answer:
area = 153.94
Step-by-step explanation:
Diameter = 14. Half of 14 is 7, so radius = 7.
Formula for the area of a circle = π * r^2, so π * 7^2 = 153.93804

x2 + 2xy + y2
Answer:
Step-by-step explanation:
This is an example of "the square of a binomial." There is a formula for such cases;
(a + b)^2 = a^2 + 2ab + b^2 (worth memorizing)
Thus, our (x + y)^2 = x^2 + 2xy + y^2

C) y=6.25x+225
D) y=-6.25+225
Are the two triangles congruent ? Please answer correctly !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!
Answer
YES
Step by step Explanation
Answer:
There is not information given to assume the triangles are congruent.
Step-by-step explanation:
You can tell if two triangles are congruent by any of the following rules:
Three sides are congruent (SSS),
Two angles and a side in between are congruent (ASA)
Two sides and an angle in between are congruent (SAS)
Two angles and a side connected to one of those angles are congruent (AAS)
Note: SSA (Two Sides & One Angle) does not work. I good way to remember is that it spells a bad word backwards :)
In this case, there are only two sides given, but there aren't any angles, so there is not enough information to conclude if they are congruent or not.

A. -√3 +2
B. √2*√3
C. √27*√ 3
D. 3√7 + 2√7-5√7
Answer:
A and B.
Step-by-step explanation:
The irrational number are -√3 +2 and √2 x √3.
What is Irrational Number?Any number that cannot be stated as a fraction for any integers is considered to be irrational. The decimal expansions of irrational numbers are neither periodic nor do they come to an end. Every number that is transcendental is illogical.
Given:
A) -√3 +2 is an irrational number.
B) √2 x √3 = √6, which is an irrational number.
C) √27 x √ 3
= 3√3 x √3
= 3 x 3
= 9, which is a rational number.
D) 3√7 + 2√7-5√7
= 5√7- 5√7
= 0, which is a rational number.

A factor of a number that, when multiplied by itself, gives the original number is called a square root.
The square root of 3 is 9.
The integer that has the nearest to the integer that has a square root of 3 is √10.
What is a square root?A factor of a number that, when multiplied by itself, gives the original number.
We have,
9 is a square root of 3.
The nearest square root of 3 can be 8 or 10.
The value of the square root of 8.
= √8
= 2.83
The value of the square root of 10:
= √10
= 3.16
The nearest can be determined by finding out the difference between each of its values with 3.
For √8,
= 3 - 2.83
= 0.17
For √10,
= 3.16 - 3
= 0.16
We see that √10 is nearest to the integer that has a square root of 3.
Thus the integer that has the nearest to the integer that has a square root of 3 is √10.

9x^2+ 3x – 2 = 0
Answer:
x=1/3, x=-2/3
Step-by-step explanation:
9x^2 +6x -3x -2=0
6x and -3x add up to 3x. You need four terms to factor.
Then you factor=
3x(3x+2)-1(3x+2)=0
(3x-1)(3x+2)=0
Then you can make two equations
3x-1=0 and 3x+2=0 because to multiply to get 0, at least one will be 0.
3x-1=0
3x=1
x=1/3
3x+2=0
3x=-2
x=-2/3
So your answers are x=1/3, x=-2/3
