Answer:
9m by 18mStep-by-step explanation:
Current drawing measurement is 40cm by 80cm using the scale 1cm:22.5cm. This scale means that the original dimension of the court has been reduced by 22.5 for every 1cm. To get the original dimension, we will multiply the given dimension by 22.5cm each as shown.
For 40cm length
Original length = 40 * 22.5
Original length = 900 cm
Convert to metres:
100cm = 1m
900cm = x
cross multiply:
100x = 900*1
x = 900/100
x = 9m
Hence 900cm = 9m
For the 80cm width:
Original width = 80 * 22.5
Original width = 1800 cm
Convert to metres:
100cm = 1m
1800cm = x
cross multiply:
100x = 1800*1
x = 1800/100
x = 18m
Hence 1800cm = 9m
Hence the length and the width of the actual court in metres is 9m by 18m
Please help on this: Given: 4c-d = f, d = c-e, f = d + e; Prove: 3c = d
Answer:
Step-by-step explanation:
Given the equations:
4c-d = f ....... 1
d = c-e....... 2
f = d + e....... 3
Substitute 2 into 1
4c -(c-e) = f
4c -c + e =f
3c + e = f ......4
Substitute equation 3 into 4:
3c+e = d+e
subtract e from both sides
3c+e-e = d+e-e
3c = c (Proved)
Solve for X: b(-4c+2x) = a(-2–qx)
Answer:
x = − 2 (a − 2 b c ) / 2 b + a q

2bx=−2a−aqx+4bc
2bx+aqx=−2a+4bc
x(2b+aq)=−2a+4bc

6-7x= 7x- 9x - 4
The value of x is _.
Answer:
x = 2
Step-by-step explanation:
Step 1: Write equation
6 - 7x = 7x - 9x - 4
Step 2: Solve for x
Combine like terms: 6 - 7x = -2x - 4Add 7x to both sides: 6 = 5x - 4Add 4 to both sides: 10 = 5xDivide both sides by 5: 2 = xRewrite x = 2Step 3: Check
Plug in x to verify it's a solution.

Suppose that 50% of the subscribers of a cable television company watch the shopping channel at least once a week. The cable company is trying to decide whether to replace this channel with a new local station. A survey of 100 subscribers will be undertaken. The cable company has decided to keep the shopping channel if the sample proportion is greater than 0.585. What is the approximate probability that the cable company will keep the shopping channel, even though the true proportion who watch it is only .50? (Round the answer to four decimal places.)
Answer:
The probability is [tex]P( p > 0.585) = 0.044565 [/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.50
The sample size is n = 100
Gnerally the mean of the sampling distribution is
[tex]\mu_x = 0.50[/tex]
Generally the standard deviation of the sampling distribution is
[tex]\sigma = \sqrt{\frac{p(1- p)}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{0.5 (1- 0.5)}{100} }[/tex]
=> [tex]\sigma =0.05[/tex]
Generally the approximate probability that the cable company will keep the shopping channel
[tex]P( p > 0.585) = P(\frac{p- \mu_{x}}{\sigma } > \frac{0.585 - 0.50}{0.05} )[/tex]
Generally [tex]\frac{p- \mu_{x}}{\sigma } = Z (The \ standardized \ value \ of p )[/tex]
=> [tex]P( p > 0.585) = P(Z > 1.7 )[/tex]
From the z-table the probability of (Z > 1.7 ) is
[tex]P(Z > 1.7 ) = 0.044565[/tex]
So [tex]P( p > 0.585) = 0.044565 [/tex]

The temperature in St. Louis is 31 degrees. The temperature in Duluth is -29 degrees. Is the temperature in St. Louis or Duluth closer to zero degrees?
Answer:
The temperature in Duluth is closer to zero
Step-by-step explanation:
-29,-28,-27,-26,-25,-24,-23,-22,-21,-20,-19,-18,-17,-16,-15,-14,-13,-12,-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31
-29<31
Answer:
Duluth
Step-by-step explanation:
The temperature in Duluth is closer to 0 degrees.
Try to think of these two numbers on a number line.
-29 degrees is 29 points away from 0 → -29 + 29 = 0
However, 31 degrees is 31 points away from 0. If you subtract Duluth's temperature from St. Louis's temperature, you get 2.
31 + (-29) = 2
Since Duluth's temperature would be exactly zero degrees and St. Louis's temperature would be two degrees from zero, Duluth is closer to zero degrees.
Hope that helps.

Amber earned $14.50 babysitting on Saturday. On Sunday, she spent $6.95 when she purchased a movie ticket. She needed to borrow money from a friend money did Amber pay for the snack if she owes her friend $5?
a. $9.50
b. $12.55
c. $16.45
d. $26.45
Answer:
I think the answer is B. $12.55
Step-by-step explanation:
14.50 - 6.95 = 7.55
7.55 + 5 = 12.55
Hi!
your answer would be: B
Reason being: If you subtract $6.95 from $14.50 you get $7.55 (which is what she had leftover after she bought the ticket). She needed $5 more to get snacks, so add $5 to $7.55 and you get $12.55.

What is the domain of the function y=tan(x/8)?
Using it's concept, it is found that the domain of the function y = tan(x/8) is given by:
All real numbers except [tex]x \neq 4\pi + 8n\pi[/tex], where n is any integer.
What is the domain of a function?It is the set that contains all possible input values for the function.
Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:
[tex]\frac{\pi}{2} + n\pi[/tex]
Hence, supposing a composite tangent function [tex]\tan{[f(x)]}[/tex], the domain is given by:
[tex]f(x) \neq \frac{\pi}{2} + n\pi[/tex]
In this problem, we have that [tex]f(x) = \frac{x}{8}[/tex], hence the domain is:
[tex]\frac{x}{8} \neq \frac{\pi}{2} + n\pi[/tex]
[tex]x \neq 4\pi + 8n\pi[/tex]

Holly is taking out a loan in the amount of $10,000. Her choices for the loan are a 4-year loan at 4% simple interest and a 6-year loan at 5% simple interest. What is the difference in the amount of interest Holly would have to pay for each of these two loans?
Answer:
The difference in the amount of interest she would have to pay for the two loans is $1,400
Step-by-step explanation:
The amount of loan Holly is taking out, P = $10,000
The choices available for the loan are;
1) Loan duration, T₁ = 4-year
Interest rate, R₁ = 4%
2) Loan duration, T₂ = 6-year
Interest rate, R₂ = 5%
For the first choice, we have;
The simple interest, I, given by the formula;
[tex]I_1 = \dfrac{P \times R_1 \times T_1 }{100} = \dfrac{10,000 \times 4 \times 4 }{100} = \$ 1,600[/tex]
For the second choice, we have;
The simple interest, I, given by the formula;
[tex]I_2 = \dfrac{P \times R_2 \times T_2 }{100} = \dfrac{10,000 \times 5 \times 6 }{100} = \$ 3,000[/tex]
The difference, D, in the amount of interest she would have to pay for the two loans is therefore;
D = I₂ - I₁ = $3,000 - $1,600 = $1,400
The difference in the amount of interest she would have to pay for the two loans = D = $1,400.

Solve for P
6p - 2 - 3p = 4
Solve for W
7w - 5 = -2w + 22
Answer:
p=2 w=3
Step-by-step explanation:
6p-2-3p=4 combine like terms. 3p-2=4. add 2 to both sides. 3p=6. divide 6 both sides by 3. p=2
7w-5=-2w+22. Combine like terms on same sides. 7w+2w=5+22. 9w=27. Divide both sides by 9. w=3.
Answer:
p = 2w = 3Step-by-step explanation:
Solve for P
6p - 2 - 3p = 4
6p - 3p = 4 + 2
3p = 6
p = 6/3
p = 2
Solve for W
7w - 5 = -2w + 22
7w + 2w = 22 + 5
9w = 27
w = 27/9
w = 3

A function takes an input of a whole number and if the number is less than 10, multiplies it by 5. If the input number is greater than or equal to 10, subtracts 5 from the input. If I input the numbers 8 and 14 into the function, what outputs should I expect to return?
Answer:
When you input 8, the output will be 40
When you input 14, the output will be 9
Step-by-step explanation:
let the function = fn
If fn < 10, then output = 5(fn)
If fn ≥ 10, then, Output = fn - 5
When you input 8 ( 8 is less than 10, then multiply by 5)
fn = 8 and 8 < 10
Output = 5(fn)
Output = 5 x 8
Output = 40
When you input 14 ( 14 is greater than 10, then subtract 5 from the input)
Output = fn - 5
Output = 14 - 5
Output = 9

All sides of a triangle combined equal 180 so you would add the values you have and then subtract it from 180
Step-by-step explanation:
We know that:-
All angles of a triangle sum up to give 180°.
So, According to Question,
[tex]20 + 87 + x = 180[/tex]
[tex]107 + x = 180[/tex]
[tex]x = 180 - 107[/tex]
[tex]x = 73[/tex]
