Answer:
B) 10 m
Step-by-step explanation:
Area is 20 and Height is 4
Ok so
AREA of a triangle is =1/2Base Times Height
work back
Area=20
Height=4
b=Base
20=1/2b*4
Simplify both sides of the equation.
20=2b
Flip equation
2b=20
Divide both sides by 2
b=10
Base=10 m
Answer:
10m
Step-by-step explanation:
Area of a triangle: [tex]\frac{1}{2}[/tex]bh
where 'b' = base and 'h' = height
plug in known values: 20 = [tex]\frac{4b}{2}[/tex]
cross-multiply: 4b = 40
b = 10

Here is the correct question:
There will be 6 people at Ellie's pie party. She wants to bake enough pie so that each person can eat at least 1/5 of a pie.What is the minimum number of pies Ellie should bake?
Since each person can eat at least 1/5 of the pie and there are 6 people, the 6 people would them eat at least (6 × 1/5) = 6/5 pie. Since we are talking about whole numbers with regards to the pie, it simply means that at least 2 pies should be baked.

A polynomial function is also:
a. infinite.
d. indiscriminate.
c. rational.
d. irrational.
Answers
Answer:
A. Infinite
Step-by-step explanation:
First lets define a polynomial function. A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation.
Well Infinite functions are functions that have an answer of all real numbers right? So that would make sense.
Honestly I've never heard of an indiscriminate.
Irrational function has answers that can only be zero or above never negative because its inside a radical sign and radical answers can't be negative. If you've ever seen the graph of an irrational function though it looks nothing like a polynomial.
A rational function is a function that the polynomial in it does not equal zero.
A polynomial function is not always a rational function though. But it can be.

Kristen is making accessories for the soccer team. She uses 763.98 inches of fabric on headbands for 32 players and 2 coaches. She also uses 272.32 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answers
Answer:
22.47 in of fabric on headbands
8.51 in of fabric on wristbands
Step-by-step explanation:
Step one:
given data
the total amount of person players plus coaches= 32+2= 34
for each person she uses = 763.98/32= 22.47 in of fabric on headbands
She also uses 272.32 inches of fabric on wristbands for just the players
For each player, she will use= 272.32/32= 8.51 in of fabric
Hence for each player, she used
22.47 in of fabric on headbands
8.51 in of fabric on wristbands.

When a point moves right on a coordinate plane,
what happens to its x-value?
Answers
Answer:
The coordinate plane is like a cross right? Just remember if you go right the x value is going into the positive direction, if you go up the y value is also going into the positive direction. And positive direction means the value will increase.
So (3,0), would be further left than (10,0). Or (0,5) would be higher than (0,2) on the graph.

I'm going to answer the solution in Point-Slope and Slope-Intercept.
Slope - Intercept form is this: y = mx + b
We know that (x, y) is a point on the line, m is the slope, and b is the y-intercept.
From the given information we have that it has a slope of 2 (m = 2), and one of the points on the line is (3, 9) which means that (x = 3, y = 9)
Plugging in we get:
y = mx + b
9 = 2*3 + b
9 = 6 + b
b = 3
Therefore the y-intercept is 3. After having this information we can construct our equation.
We now have to put this in the point-slope form which is: (y - y1) = m(x - x1)
Transferring what we had before we can plugin and get y - 9 = 2(x - 3)
Comment down if you have any queries or any questions on the solution. Tell me as soon as possible. Good luck in your Algebra Pursuit!! :)
Enjoy!! I put the answer in both point-slope and slope-intercept if you haven't noticed!! :)
So our answer is:
y - 9 = 2(x - 3).
2x + 2y = 350
What is X and Y?
Answers

If 2a+4b=5 and a is equal to three times b, what is 3a?
Answers
Answer:
3a=4.5
Step-by-step explanation:
it says that "a is equal to 3 times b", which translates to a=3b
We can substitute a as 3b in 2a+4b=5
2(3b)+4b=5
multiply
6b+4b=5
add
10b=5
divide by 10
b=1/2
since it's given that a=3b, we can multiply 1/2 by 3
a=3/2
3a is 3 times a, so we can mutiply 3(3/2)=9/2=4.5

A roofing contractor has 29 bundles of roofing shingles that he needs to carry up a ladder and put onto a roof he carries two bundles at a time how many bundles are still on the ground after his seventh trip up the ladder
Answers
Answer:
15 bundles of roofing shingles
Step-by-step explanation:
Total bundles of roofing shingles = 29
He carries two bundles at a time
How many bundles are still on the ground after his seventh trip up the ladder?
First trip = 2 bundles of roofing shingles
Second trip = 2 bundles of roofing shingles
Third trip = 2 bundles of roofing shingles
Fourth trip = 2 bundles of roofing shingles
Fifth trip = 2 bundles of roofing shingles
Sixth trip = 2 bundles of roofing shingles
Seventh trip = 2 bundles of roofing shingles
Total bundles of roofing shingles carried in 7 trips = 2 + 2 + 2 + 2 + 2 + 2 + 2
= 14 bundles of roofing shingles
Bundles still on ground after 7 trips = Total bundles of roofing shingles - Total bundles of roofing shingles carried in 7 trips
= 29 - 14
= 15 bundles of roofing shingles

Rewrite 300 in simplest radical form?
Answers
Answer:
10√3
Step-by-step explanation:
First we write the square root of 300 like this:
√300
The largest perfect square of the factors of 300 is 100. We can therefore convert √300 like this:
√100 × 3
Next, we separate the numbers inside the √ as such:
√100 × √3
√100 is a perfect square that equals 10. We can therefore put 10 outside the radical and get the final answer to square root of 300 in simplest radical form as follows:

Simplify
In trigonometry:
[tex]tan(30^{\circ}) = \frac{1}{\sqrt{3}}[/tex]
So, the expression becomes:

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{\frac{2}{\sqrt{3}}}{1 + \frac{1}{3}}[/tex]

[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{\frac{2}{\sqrt{3}}}{ \frac{4}{3}}[/tex]
Express the fraction as:
[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex][tex]= \frac{2}{\sqrt 3} / \frac{4}{3}[/tex]
[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{2}{\sqrt 3} * \frac{3}{4}[/tex]
[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{1}{\sqrt 3} * \frac{3}{2}[/tex]
[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{3}{2\sqrt 3}[/tex]
Rationalize
[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{3}{2\sqrt 3} * \frac{\sqrt{3}}{\sqrt{3}}[/tex]
[tex]\frac{2tan30^{\circ}}{1 + tan^2(30^{\circ})}[/tex] [tex]= \frac{3\sqrt{3}}{2* 3}[/tex]

Answers
Answer:
The volume of the Pyramid is 318.3 cubic foot
Step-by-step explanation:
Here, we want to calculate the volume of the Pyramid
Mathematically, the volume of the pyramid is the area of the square base multiplied by the height of the Pyramid.
Since the perimeter is 15.8 and the formula for the perimeter is 4L
we can get the length of the side of the square
The length of the side will be 15.8/4 = 3.95
The area of the square base is thus equal to;
3.95^2 = 15.6025 square feet
Now we can multiply this by the height
Mathematically, that will be;
15.6025 * 20.4 = 318.291 which is approximately 318.3 cubic foot

106.1 ft
