A builder buys a piece of property with 16.1 acres of land to develop a new set of walking trails and baseball fields. The builder plans to use 0.33 of the property for baseball fields. How many acres will the builder use for the baseball fields?
Answer:
The builder will use 5.28 acres of land for baseball fields.
Step-by-step explanation:
This question can be solved using a rule of three.
The property has 16.1 acres of land. This is 100% = 1. 33% will be used for baseball fields. How much is 0.33?
16.1 - 1
x - 0.33
[tex]x = 16*0.33 = 5.28[/tex]
The builder will use 5.28 acres of land for baseball fields.
Convert 63 degrees C to
degrees F.
Celcius to fahrenheit conversion is just using this formula
(x°C × 9/5) + 32 = y°F
where x is the degrees in celcius and y is the degrees in fahrenheit.
Le'ts plug in 63 into the equation
63 x 9/5=113.4+32=145.4 degrees fahrenheit.

Answer:
[tex]x=\frac{7}{2} =3.5\\\\y=2[/tex]
Step-by-step explanation:
The addition method (elimination method) allows us to combine two equations in such a way that the resulting equation has only one variable. Then we can use simple algebraic methods to solve that variable
Let:
[tex]4x-6y=2\hspace{10}(1)\\\\and\\\\2x-y=5\hspace{15}(2)[/tex]
Let's multiply (2) by -2:
[tex]-2*(2):\\\\2x(-2)-y(-2)=5(-2)\\\\-4x+2y=-10\hspace{12}(-2*(2))[/tex]
Now, add (1) and (-2*(2)):
[tex](1)+(-2*(2)):\\\\4x+(-4x)-6y+(2y)=2+(-10)\\\\-4y=-8[/tex]
Hence, solving for y:
[tex]y=\frac{-8}{-4} =2[/tex]
Replacing y into (2):
[tex]2x-(2)=5[/tex]
Solving for x:
[tex]2x=5+2\\\\2x=7\\\\x=\frac{7}{2} =3.5[/tex]
Therefore:
[tex]x=\frac{7}{2} =3.5\\\\y=2[/tex]

When the volume of a gas is
changed from mL to 852 mL,
the temperature will change from
315°C to 452°C.
Answer: The initial volume is 593.76mL
Step-by-step explanation:
As you do not say anithing about the pressure, i guess that the pressure remains constant.
If the gas is an ideal gas, we have:
P*V = n*R*T
where P is pressure, n is number of moles and R is a constant.
Now, initially we have:
P*Vi = n*R*315°C
finally we have:
P*825mL = n*R*452°C
Now we can take the quiotient of those two equations and get:
(P*Vi)/(P*852mL) = (n*R*315°C)/( n*R*452°C)
Now we have:
Vi/852mL = 315/452
Vi = (315/452)*852mL = 593.76mL
So when we expand the gas at constant pressure, we increase the temperature.
Answer:
691 mL

Which equation could generate the curve in the graph below?
Answer:
[tex]y=2x^2+8x+8[/tex]
Step-by-step explanation:
Notice that we are looking for a quadratic function that has only one real solution for y=0, that is a unique point that touches the x-axis
We need therefore to look at the discriminant associated with all 4 equations constructed by equaling y to zero. We then try to find one that gives discriminant zero , corresponding to a unique real solution to the equation.
a) [tex]9x^2+6x+4=0[/tex] has discriminant: [tex]6^2-4(9)(4)=-108[/tex]
b) [tex]6x^2-12x-6=0[/tex] has discriminant: [tex](-12)^2-4(6)(-6)=288[/tex]
c) [tex]3x^2+7x+5=0[/tex] has discriminant: [tex](7)^2-4(3)(5)=-11[/tex]
d) [tex]2x^2+8x+8=0[/tex] has discriminant: [tex](8)^2-4(2)(8)=0[/tex]
Therefore, the last function is the one that can have such graph

Answer:
x=9
Step-by-step explanation:
first you would distribute the -4 and the -12
-24x-12=-12x-120
Then you would add 120 to both sides
-24x+108=-12x
Then add 24x to both sides
108=12x
Then divide both sides by 12
x=9
Answer:
[tex]x = 9[/tex]
Step-by-step explanation:
[tex] - 4(6x + 3) = - 12(x + 10) \\ - 24x - 12 = - 12x - 120 \\ - 24x + 12x = 12 - 120 \\ - 12x = - 108 \\ \frac{ - 12x}{ - 12} = \frac{ - 108}{ - 12} \\ x = 9[/tex]

At the start of 2014 Mike's car was worth £12000.
The value of the car decreased by 30% every year.
Work out the value of his car at the start of 2017.
The value of Mike's car at the start of 2017 is £4116.
What is percentage ?
Percentage is a ratio in the form of fraction of 100.
Percentage is defined by the "%" symbol.
What is the required value of the car ?At the start of the year 2014, Mike's car was worth £12000.
The value of the car decreased by 30% every year.
So, The value of the car at the start of 2015 = £12000×[tex](1-\frac{30}{100})[/tex]
= £ 12000×[tex]\frac{7}{10}[/tex]
= £ 8400
Again, The value of the car at the start of 2016 = £8400×[tex](1-\frac{30}{100})[/tex]
= £8400×[tex]\frac{7}{10}[/tex]
= £5880
∴ The value of the car at the start of 2017 = £5880×[tex](1-\frac{30}{100})[/tex]
= £5880×[tex]\frac{7}{10}[/tex]
= £4116

If the first three Fibonacci nos. are x1=1, x2=1 and x3=2, what is the value of n for which xn + xn+1 = 89 ?
Answer:
11
Step-by-step explanation:
Looking at Fibonacci numbers ;
We have:
Than X1 =1 ; X2 = 1; X3 = 2
Xn+1 = Xn + Xn-1
X3 = X2 + X1 = 1+1 =2; X4 = X3 + X2 = 2 +1 = 3; X5= X4+X3 = 3+2 = 5; X6 = X5 + X4 = 5 + 3 = 8; X7 = X6 +X5 = 8 +5 = 13; X8 = X7 + X6 = 13 + 8 = 21; X9 = X8 + X7 = 21+ 13 = 34 ; X10 = X9 + X8 = 34 +21 = 55 ; X11 = X10 + X9 = 55 +34 = 89
We see that ; X11 gives 89 so the value of n = 11

Triangle RST is drawn inside rectangle RSNM. Point T is halfway between points M and N on the rectangle. The length of side RS is 9 in. and the length of side RM is 8 in.
1) What is the area of triangle RST?
2)What is the ratio of area of triangle RST to area of triangle RMT?
3) What is the area of rectangle RSMN to area of triangle TSN?
Diagram is attached.
Answer:
1) 36 sq.in
2) 2:1
3) 4:1
Step-by-step explanation:
1) Area of triangle is; ½ × base × height.
For triangle RST, base = 9 in and height = 8 in
Thus, area of triangle RST = ½ × 9 × 8
= 36 sq.in
2)Area of triangle RMT = ½ × 8 × 9/2
= 18 sq.in
Ratio of area of RST to area of RMT = 36/18 = 2:1
3)Area of triangle TSN = ½ × 8 × 9/2 = 18 sq.in
Area of Rectangle RSNM = Length x width = 9 × 8 = 72 sq.in
Ratio of Area of Rectangle RSNM to Area of triangle TSN = 72/18 = 4:1

A binomial probability experiment is conducted with given parameters. Compute the probability of x successes in the n independent trials of the experiment.
N=15, p=0.2,×=4
Answer:
P(X = 4) = 0.1876
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
In this question:
[tex]n = 15, p = 0.2[/tex]
We want P(X = 4). So
[tex]P(X = 4) = C_{15,4}.(0.2)^{4}.(0.8)^{11} = 0.1876[/tex]
Find the number of unique permutations of the letters in the word: EXTENT

Answer:
180
Step-by-step explanation:
A word has n letters.
There are m repeating letters, each of them repeating [tex]r_{0}, r_{1}, ..., r_{m}[/tex] times
So the number of distincts ways the letters can be permutated is:
[tex]N_{A} = \frac{n!}{r_{1}! \times r_{2}! \times ... \times r_{m}}[/tex]
In this question:
Extent has 6 letters.
E and r repeat 2 times. So
[tex]N = \frac{6!}{2!*2!} = 180[/tex]
So the answer is 180.

William wants to invest $30,000 in a mutual fund.
a) Bank A has an annual interest rate of 6.5% for 5 years. How much money will he have
at the end of the 5 years? $
Answer:
He will have $39,750 at the end of five years.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
[tex]T = E + P[/tex]
In this question:
[tex]P = 30000, I = 0.065, t = 5[/tex]
Interest earned:
[tex]E = P*I*t = 30000*0.065*5 = 9750[/tex]
Total amount:
[tex]T = E + P = 9750 + 30000 = 39750[/tex]
He will have $39,750 at the end of five years.
According to the Gallup survey, 23% of Americans reported eating less meat in the past year than they had previously. Results for this Gallup poll are based on telephone interviews conducted Sept. 16-30, 2019, with a random sample of 2,431 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia. Test that the proportion of Americans who reduced meat consumption last year is less than 0.25. Use α = 0.05. State the rejection region. Group of answer choices z > 1.65 z > 1.65 z < − 1.65 z < − 1.65 z > 1.96 z > 1.96
Answer:
Null hypothesis:[tex]p\geq 0.25[/tex]
Alternative hypothesis:[tex]p < 0.25[/tex]
The statistic would be given by:
[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)
Now we need to find the critical value for the rejection zone of the null hypothesis. Since we have a left tailed test we need to find in the normal standard distirbution a value who accumulate 0.05 of the area in the left tail and we got:
[tex] z_{crit}= -1.65[/tex]
And the best choice for this case would be:
z < − 1.65
Step-by-step explanation:
Information provided
n=2431 represent the random sample taken
[tex]\hat p=[/tex] estimated proportion of interest
[tex]p_o=0.25[/tex] is the value that we want to test
[tex]\alpha=0.05[/tex] represent the significance level
Confidence=95% or 0.95
z would represent the statistic
Hypothesis to test
We want to verify if the true proportion of Americans who reduced meat consumption last year is less than 0.25, then the system of hypothesis are :
Null hypothesis:[tex]p\geq 0.25[/tex]
Alternative hypothesis:[tex]p < 0.25[/tex]
The statistic would be given by:
[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)
Now we need to find the critical value for the rejection zone of the null hypothesis. Since we have a left tailed test we need to find in the normal standard distirbution a value who accumulate 0.05 of the area in the left tail and we got:
[tex] z_{crit}= -1.65[/tex]
And the best choice for this case would be:

Find the slope-intercept form of the equation of the line
passes through the point (-5, -4) and has slope 4.
Answer:
y= 4x +16
Step-by-step explanation:
slope-intercept form:
y=mx+c, where m is the gradient and c is the y-intercept
Given that the slope is 4, m=4.
y= 4x+c
To find the value of c, substitute a coordinate.
When x= -5, y= -4,
-4= 4(-5) +c
-4= -20 +c
c= 20 -4
c=16
Thus, the equation of the line is y= 4x+16.
