Answer:
12
Step-by-step explanation:
The formula to find the area of a circle is:
[tex]\pi[/tex][tex]r^{2}[/tex]
Where "r" is the radius of the circle.
In this case, the radius is 2, and as per what is given in this problem (what the problem asks one to use), pi is rounded down to 3.
The equation will be:
3 * 2^2
Simplify, remember the order of operations:
3 * 4
12
Answer:
12.56 cm
Step-by-step explanation:
Area of a circle is A=3.14 r to the second power.
so the radius is 2 cm. I would do 2 x 2 and that equals ,4 next 4 x 3.14= 12.56
i don't know what pie=3 means but this is my answer from the best of my ability.

How would you solve |10+4x|<14
And how would you graph it on a number line?
Answer:
x < 1
Step by step explanation:
10 + 4x < 14
4x < 14 -10
4x < 4
x < 1
When you graph it on a number line, draw a line that extends from 1 towards the left side (since x is less that 1) and use unshaded circles.

The Wright family budget allows
twice as much money for rent as
for food. Their budget allows
less than $720 for both food and
rent. What is the most they can
spend on food?
Answer:
The most that they can spend in food is $239
Step-by-step explanation:
Their budget allows for less than $720 for both food and rent.
We are told that this budget allows
twice as much money for rent as
for food.
Thus,
Let x be amount of spent on food.
Thus, money spent on rent is 2x
Thus,
2x + x < 720
3x < 720
x < 720/3
x < 240
Since x should be less than 240,it means that the most that they can spend in food is $239

(a) 2(1)^4 + 3(1)^3 - (1)^3 + 2(1) - 3
2 + 3 - 1 + 2 - 3 = 1 + 2 = 3
f(1) = 3
(b) 2(-1)^4 + 3(-1)^3 - (-1)^2 + 2(-1) - 3
2 * 1 + 3(-1) - 1 + 2(-1) - 3
2 + -3 -1 -2 - 3 = 2 - 9 = -7
f(-1) = -7
(c) 2(0) + 3(0) - 0 + 0 - 3
0 - 3 = -3
f(0) = -3
d) 2(-1/2)^4 + 3(-1/2)^3 - 2(-1/2) - 3
1/8 - 3/8 - (-1/2)^2 - 2 * 1/2 - 3
16/4 - 1/4 - 1/4 = -16-1-1/4 = -18/4
f(-1/2) = -9/2

1. Jun needs to review for the entrance exam with his remaining 5 3/5 hours fo the 7 subjects. how long will he spend for each subject?
2.Mar purchased 6 3/4 meters of wall paper for the boxes he will cover. if each box needs 2 1/4 meters, how many boxes will get covered?
3.Joana has 12 1/4 meters of ribbon, joy has 3meters ribbon shorter than joana. they split the ribbon to have the an equal length of ribbon. how long is each piece
Answer: See explanation
Step-by-step explanation:
1. Jun needs to review for the entrance exam with his remaining 5 3/5 hours fo the 7 subjects. how long will he spend for each subject?
The time spent on each subject will be the remaining hours left divided by 7. This will be:
= 5 3/5 ÷ 7
= 28/5 ÷ 7
= 28/5 × 1/7
= 28/35 = 4/5 hours
Since 60 minutes make one hour
4/5 hours = 4/5 × 60 = 48 minutes
2.Mar purchased 6 3/4 meters of wall paper for the boxes he will cover. if each box needs 2 1/4 meters, how many boxes will get covered?
This will be:
= 6 3/4 ÷ 2 1/4
= 27/4 ÷ 9/4
= 27/4 × 4/9
= 3 boxes
3.Joana has 12 1/4 meters of ribbon, joy has 3meters ribbon shorter than joana. they split the ribbon to have the an equal length of ribbon. how long is each.
Joana ribbon = 12 1/4 meters
Joy's ribbon = 12 1/4 - 3 = 9 1/4 meters
We then add both length of ribbons and divide by 2. This will be:
= 12 1/4 + 9 1/4
= 21 1/2 meters
= 21 1/2 meters ÷ 2
= 43/2 ÷ 2
= 43/2 × 1/2
= 43/4
= 10 3/4 meters

............................
To prepare for wrestling season, Tommy wants to eat 24 grams of protein at breakfast. He knows that there are 3 grams of protein in a slice of bacon and 6 grams of protein in an egg. Let x represent the number of slices of bacon he will eat and let y represent the number of eggs he will eat.
Write an equation that relates the number of slices of bacon to the number of eggs he will eat, assuming he eats exactly 24 grams of protein. **Rewrite your equation in slope-intercept form.
Answer:
1) The equation that represents the number of slices of bacon to the number he will eat, assuming he eats 24 grams is;
3·x + 6·y = 24
2) The equation in slope and intercept form is;
y = 4 - 0.5·x
Step-by-step explanation:
1) The given parameters are;
The amount of protein Tommy wants to eat for breakfast = 24 grams
The quantity of protein in a slice of bacon = 3 grams
The quantity of protein in an egg = 6 grams
Let x represent the number of slices of bacon he will eat and let y represent the number of eggs he will eat
The equation that represents the number of slices of bacon to the number he will eat, assuming he eats 24 grams is given as follows;
3·x + 6·y = 24
2) The equation in slope and intercept form is given by making y the subject of the above equation as follows;
3·x + 6·y = 24
6·y = 24 - 3·x
y = 24/6 -1/2·x
y = 4 - 0.5·x, which is in the slope and intercept form y = m·x + c
Where;
m = The slope = -0.5
c = The y-intercept = 4

Step-by-step explanation:
f. How many times greater is the area of triangle DEF
than the area of triangle ABC? Show/explain.
Answer:
Area of ΔDEF is 2.25 times the area of ΔABC.
Step-by-step explanation:
Since, ΔDEF is the enlarged form of ΔABC,
Scale factor = [tex]\frac{\text{Side length of triangle ABC}}{\text{Corresponding side length of image triangle}}[/tex]
= [tex]\frac{15}{10}[/tex]
= 1.5
Since, ratio of the areas of image and preimage triangles = (Scale factor)²
[tex]\frac{\text{Area of image triangle}}{\text{Area of triangle ABC}}[/tex] = (Scale factor)²
[tex]\frac{\text{Area of image triangle}}{\text{Area of triangle ABC}}=(1.5)^2[/tex]
Area of image ΔDEF = 2.25(Area of ΔABC)
Therefore, area of ΔDEF is 2.25 times the area of ΔABC.

Write the polynomial in standard form. State the degree and leading coefficient:
−9 + 7m^3 − 11m + 3/5m^5
Degree:_____________
Leading Coefficient:_____________
Answers:
Standard form = [tex]\frac{3}{5}m^5 + 7m^3 - 11m-9[/tex]Degree = 5Leading coefficient = 3/5===================================================
Explanation:
The largest exponent term is what will go first. Then the term with the second largest goes next, and so on. We count the exponents down. The exponents will count down in this case as 5, 3, 1, 0
Note: -9 = -9*1 = -9m^0 and -11m = -11m^1
So that's why standard form is [tex]\frac{3}{5}m^5 + 7m^3 - 11m-9[/tex]
We can write this as (3/5)m^5 + 7m^3 - 11m - 9
------------------------
The leading term is the first term after getting everything in standard form. The coefficient of the leading term is the leading coefficient. So in this case, it would be 3/5.
The degree is the largest exponent. So the degree is 5. This is a quintic polynomial.
1l) HAO WENT TO A HOBBY SHOP AND SAW A DISPLAY OF TOY TRAINS. THE SIGN IN FRONT OF THE DISPLAY SAID THAT THE TOY TRAINS WERE A REPLICA OF THE LONG ISLAND RAILROAD TRAINS. HAO ESTIMATED THAT ONE OF THE RAILROAD CARS WAS APPROXIMATELY 15 INCHES LONG AND 4 INCHES WIDE. THE SIGN IN FRONT OF THE DISPLAY STATED "SCALE- 2 /9". WHAT IS THE LENGTH OF THE RAILROAD CAR ON THE LONG ISLAND RAILROAD? WHAT IS THE WIDTH OF THE LONG ISLAND RAILROAD CAR?
Answer:
Step-by-step explanation:
Given that :
Dimension of rail road toy trains :
Length = 15 inches
Width = 4 inches
Scale = 2/9
Dimension of car on the long Island rail road :
Let length = x
Length = 2/9 of x = 15 inches
= 0.22222x = 15 inches
LENGTH = 67.5 inches
WIDTH = 2/9 of x = 4 inches
0.22222x = 4 inches
Width = 18
Width = 6 inches

How can ure out the next number in the pattern below? Write a conjecture that describes the pattern.
29, 28, 26, 23, 19
The difference between consecutive first and second integers is increased by 1 thus the next number 19 - x = 5 → x = 14.
What is the pattern?A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.
For example 2,4,6,8 in this, the difference between any two-term is only 2 and this will be its specific pattern.
As per the given pattern,29, 28, 26, 23, 19
29 - 28 = 1
28 - 26 = 2
26 - 23 = 3
23 - 19 = 4
Since the difference is increasing by 1
So the difference of 19 and the next number (x) will be 4 + 1 = 5.
19 - x = 5
x = 14
Hence "The difference between consecutive first and second integers is increased by 1 thus the next number 19 - x = 5 → x = 14".

the area of a right triangle is 12in^2. the ratio of the length of its legs is 2:3. Find the length of the hypotenuse.
a) square root is 13 in
b) 26 inches
c) 2 square root of 13
d) 52 inches
e) 4 square root of 13
Answer:
The length of the hypotenuse is 2 square root of 13 ⇒ c
Step-by-step explanation:
The rule of the area of the right triangle is A = [tex]\frac{1}{2}[/tex] × leg1 × leg2, where
leg1 and leg2 are the sides of the right angle
∵ The area of a right triangle is 12 in²
∵ The ratio of the length of its legs is 2: 3
→ Let leg1 = 2x and leg2 = 3x
∵ leg1 = 2x and leg2 = 3x
→ Substitute them in the rule of the area above
∴ 12 = [tex]\frac{1}{2}[/tex] × 2x × 3x
∵ 2x × 3x = 6x²
∴ 12 = [tex]\frac{1}{2}[/tex] × 6x²
∴ 12 = 3x²
→ Divide both sides by 3 to find x²
∴ 4 = x²
→ Take √ for both sides
∴ x = 2
→ Substitute x in the expressions of leg1 and leg2 to find them
∴ leg1 = 2(2) = 4 inches
∴ leg2 = 3(2) = 6 inches
∵ hypotenuse = [tex]\sqrt{(leg1)^{2}+(leg2)^{2}}[/tex]
∴ hypotenuse = [tex]\sqrt{(4)^{2}+(6)^{2}}=\sqrt{16+36}=\sqrt{52}[/tex]
∵ The simplest form of [tex]\sqrt{52}[/tex] = 2[tex]\sqrt{13}[/tex]
∴ The length of the hypotenuse = 2[tex]\sqrt{13}[/tex] inches

What is the solution of the system? Use elimination.
2x + 2y +z = 7
-X – y +z = -5
x + 3y – 4z = 12
Answer:
The solutions to the system of the equations by the elimination method will be:
[tex]x=2,\:z=-1,\:y=2[/tex]
Step-by-step explanation:
Given the system of the equations
[tex]2x\:+\:2y\:+z\:=\:7[/tex]
[tex]-x-\:y\:+z\:=\:-5[/tex]
[tex]x+3y-4z=12[/tex]
solving the system of the equations by the elimination method
[tex]\begin{bmatrix}2x+2y+z=7\\ -x-y+z=-5\\ x+3y-4z=12\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}-x-y+z=-5\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-2x-2y+2z=-10[/tex]
[tex]\begin{bmatrix}2x+2y+z=7\\ -2x-2y+2z=-10\\ x+3y-4z=12\end{bmatrix}[/tex]
[tex]-2x-2y+2z=-10[/tex]
[tex]+[/tex]
[tex]\underline{2x+2y+z=7}[/tex]
[tex]3z=-3[/tex]
[tex]\begin{bmatrix}2x+2y+z=7\\ 3z=-3\\ x+3y-4z=12\end{bmatrix}[/tex]
[tex]2x+6y-8z=24[/tex]
[tex]-[/tex]
[tex]\underline{2x+2y+z=7}[/tex]
[tex]4y-9z=17[/tex]
[tex]\begin{bmatrix}2x+2y+z=7\\ 3z=-3\\ 4y-9z=17\end{bmatrix}[/tex]
Rearranging the equations
[tex]\begin{bmatrix}2x+2y+z=7\\ 4y-9z=17\\ 3z=-3\end{bmatrix}[/tex]
solve [tex]3z=-3[/tex] for z:
[tex]z=-1[/tex]
[tex]\mathrm{For\:}4y-9z=17\mathrm{\:plug\:in\:}z=-1[/tex]
solve [tex]4y-9\left(-1\right)=17[/tex] for y:
[tex]4y-9\left(-1\right)=17[/tex]
[tex]4y+9=17[/tex]
[tex]4y=8[/tex]
[tex]y=2[/tex]
[tex]\mathrm{For\:}2x+2y+z=7\mathrm{\:plug\:in\:}z=-1,\:y=2[/tex]
solve [tex]2x+2\cdot \:2-1=7[/tex] for x:
