Answer: A) 7.1 square feet
Step-by-step explanation:
area of a circle= πr^2
given,
d=3 feet=3/2=1.5 feet
hence,
area of a circle= πr^2
= 3.14×(1.5)^2
= 7.065
=7.1 square feet.
A bag contains 2 1/4 kilograms of flour. Anthony needs 3 1/2 bags of flour to make bread. How many kilograms of flour does anthony need?
6 1/8
6 3/4
7 3/8
7 7/8
Answer:
7 7/8
Step-by-step explanation:
Covert the mixed fractions into improper fractions to make this easier.
2 [tex]\frac{1}{4} and 3\frac{1}{2}[/tex] into [tex]\frac{9}{4} (2*4 +1) and \frac{7}{2} (3*2+1)[/tex]. (In parenthesis, its the process of creating the improper fractions and not part of the fractions themselves.
Now you just multiply both together since 1 bag needs 2 1/4 kilograms and Anthony needs 3 1/2 bags.
That gets you [tex]\frac{63}{8}[/tex] which you get by multiplying 9 and 7 in the numerator and 4 and 2 in the denominator
Finally, find out how many 8 goes into 63 which would be 7 times. 63-(7*8) = 7.
And so the answer is 7 7/8

Ratios and proportionRatios are written as fractions or in the form a:b.
According to the question, An IV piggyback (IVPB) of 10,000 units/100 mL is to be given over 45 minutes.
We are to determine the number of mL to be given in 60 minutes (1 hr)
100mL = 45 minutes
x mL = 60 minutes
Take the ratio
100/x = 45/60
Cross multiply
45x = 6000
x = 6000/45
x = 133mL/hr
Hence the pump should be programmed to deliver 133mL/hr

Find the solutions to the rational equation:
x+2 2x-4
3
2
(2 pts)
A
X = 2
B
x = 6
с
x = -2
D
x = 4
Answer:
D
Step-by-step explanation:
[tex]\frac{x+2}{3}[/tex] = [tex]\frac{2x-4}{2}[/tex] ( cross- multiply )
3(2x - 4) = 2(x + 2) ← distribute parenthesis on both sides
6x - 12 = 2x + 4 ( subtract 2x from both sides )
4x - 12 = 4 ( add 12 to both sides )
4x = 16 ( divide both sides by 4 )
x = 4
[tex] \longrightarrow \frac{x + 2}{3} = \frac{2x - 4}{2} [/tex]
What to Find : -In this question we have to find the value of x .
Let's Get start Solving : -[tex]\longrightarrow \frac{x + 2}{3} = \frac{2x - 4}{2} [/tex]
So , by cross multiplying :
[tex] \longrightarrow \: 2(x + 2) = 3(2x - 4)[/tex]
Now , calculation left hand side as well as right hand side :
[tex]\longrightarrow \: 2x + 4 = 6x - 12[/tex]
Now , transposing 6x to left hand side and 4 to right hand side :
[tex]\longrightarrow \: 2x - 6x = - 12 - 4[/tex]
Now , solving left hand side and right hand side :
[tex]\longrightarrow \: - 4x = - 16[/tex]
As negative sign is present on both the side , so it will cancel out :
[tex]\longrightarrow \: \cancel - 4x = \cancel- 16[/tex]
Now we have :
[tex]\longrightarrow \: 4x = 16[/tex]
Now we are transposing 4 to right side and it will change into division from multiplication :
[tex]\longrightarrow \: x = \cancel \frac{16}{4} [/tex]
So we get :
[tex]\longrightarrow \: \green{ \boxed{ \bold x = 4}}[/tex]
Therefore value of x is 4 .Verification : -We are verifying our answer by putting value of x in given question :
[tex]\longrightarrow \frac{4 + 2}{3} = \frac{2(4) - 4}{2} \: [/tex]
Solving ,
[tex]\longrightarrow \: \frac{6}{3} = \frac{8 - 4}{2} [/tex]
Now subtracting 8 and 4 :
[tex]\longrightarrow \: \frac{6}{3} = \frac{4}{2} [/tex]
Now , dividing 6 by 3 and 4 by 2 :
[tex]\longrightarrow \cancel{\frac{6}{3} } = \cancel{\frac{4}{2} }[/tex]
We get :
[tex]\longrightarrow \: \bold{2 = 2}[/tex]
That means ,
[tex]\longrightarrow L.H.S = R.H.S[/tex]
Hence Verified .Therefore our answer is correct .#[tex] \sf{Keep \: Learning}[/tex]To the nearest whole percent, what is the value of a in the relative frequency table for the survey results? a = 27% a = 42% a = 81% a = 88%

Solve x2 14x = −24 by completing the square. what is the solution set of the equation?
Answer:
(-12, -2)
Step-by-step explanation:
Rearrange the equation --> x^2 + 14x + 24 = 0
Split 14x into 12x + 2x --> x^2 + 12x + 2x + 24 = 0
Group --> x(x + 12) + 2(x + 12) = 0, (x + 12)(x + 2) = 0
Find roots:
x + 12 = 0, x = -12
x + 2 = 0, x = -2
The solution of the given expression [tex]\rm x^{2} +14x = -24\\[/tex] by completing the square method is 12 and -2.
The given expression is
[tex]\rm x^{2} +14x = -24\\[/tex]
What is completing the square method?In completing the square, we take half of the coefficient of the middle term and then square it. Then we add it to both sides of the equation
Here coefficient of middle term x is +14.
So, 14/2 = 7
square of 7 is 49
[tex]\rm x^{2} +14x +49= -24+49\\\rm (x+7) (x+7)=25\\\rm (x+7)^{2} =5^{2} \\\rm x+7 =5[/tex]
x+7 = 5 and x+7 = -5
Solve for x by subtracting 7 on both sides
x = -2 and x= -12
Solution set is {-12, -2}

Is this triangle acute, right or obtuse?
Answer:
acute
Step-by-step explanation:
Check using the Pythagorean Theorem:
A^2 + B^2 ≟ C^2
9^2 + 115 ≟ 11^2
196 > 121,
so this triangle is acute because the sum of each leg squared is longer than the length of the hypotenuse squared.

Calculate the zeros of the function f(x) = x2 – 12x + 35 by completing the square.
Answer:
x = 5, x = 7
Step-by-step explanation:
to find the zeros let f(x) = 0 , that is
x² - 12x + 35 = 0 ( subtract 35 from both sides )
x² - 12x = - 35
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 6)x + 36 = - 35 + 36
(x - 6)² = 1 ( take the square root of both sides )
x - 6 = ± [tex]\sqrt{1}[/tex] = ± 1 ( add 6 to both sides )
x = 6 ± 1
then
x = 6 - 1 = 5
x = 6 + 1 = 7
