A cinema screens two different short films at two separate rooms at regular intervals throughout the day. The first film lasts for $$50 minutes, while the second film lasts for $$30 minutes. There are $$10-minute breaks between the screening of a film in each room. If the cinema starts screening both films at $$2:45 pm when it opens for the day, what is the next time that both films will start screening at the same time?
Answer:
4: 45pm
Step-by-step explanation:
First Film = 50 minutes
Second Film = 30 minutes
Cinema start screening time = 2:45 pm

Delanie deposited $3,000 into an account that earns 2.5% interest compounded annually. After 2 years, how much interest in dollars and cents will her investment pay?
The amount of interest that should her investment pay should be considered as the $3,152.
Calculation of the amount of interest:Since
The deposited amount is $3,000
The rate of interest is 2.5%
And, the number of years should be 2
So here the interest be like
[tex]= \$3,000 * (1 + 0.025)^2[/tex]

Evaluate 5÷9(F - 32) when f=50
1. Find the 90% Cl for the population mean if sample
mean= 12, SD=2.3 and sample size is 65.
2. Find the 88% Cl for the population mean if sample
mean=23, SD=12, and sample size is 45.
3. Interpret #1 and #1.
Answer:
The answer is below
Step-by-step explanation:
1)
mean (μ) = 12, SD(σ) = 2.3, sample size (n) = 65
Given that the confidence level (c) = 90% = 0.9
α = 1 - c = 0.1
α/2 = 0.05
The z score of α/2 is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.65
The margin of error (E) is given as:
[tex]E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.65*\frac{2.3}{\sqrt{65} } =0.47[/tex]
The confidence interval = μ ± E = 12 ± 0.47 = (11.53, 12.47)
2)
mean (μ) = 23, SD(σ) = 12, sample size (n) = 45
Given that the confidence level (c) = 88% = 0.88
α = 1 - c = 0.12
α/2 = 0.06
The z score of α/2 is the same as the z score of 0.44 (0.5 - 0.06) which is equal to 1.56
The margin of error (E) is given as:
[tex]E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.56*\frac{12}{\sqrt{45} } =2.8[/tex]
The confidence interval = μ ± E = 23 ± 2.8 = (22.2, 25.8)

Answer:
[tex]3-\sqrt{10}[/tex]
Step-by-step explanation:
We are given an expression and are asked to find what it equals. We can see that the two square roots are being multiplied, therefore they follow the same standard as any multiplication problem, do as followed :
[tex]\sqrt{5} *\sqrt{2}[/tex]
[tex]\sqrt{10}[/tex]
Since a square root and constant number are different terms, we cannot combine them together, therefore leave as is :
[tex]3-\sqrt{10}[/tex]

Answer:
I got 6.7 but I'm not entirely sure
Step-by-step explanation:
Pythagorean Theorem is A² + B² = C²
So you take 6² + 3² = 45
Take 45 and square root it
The answer should be 6.708, but rounding to the nearest tenth, the answer is 6.7

Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
in the picture there is a Hyp and an Opp
so, use the function that has those sin has those , huh
then,
sin(Ф) = 12/13
Ф = arcSin(12/13)
Ф = 67.38 °
now we know that angle.. now we can get cos
cos(67.38 °) = adj / 13
13 * cos(67.38 °) = adj
oh it's exactly
5 = adj
I feel like that's right since it worked out to be exactly 5 :)
Cos(Ф) = 5 / 13
there is your answer :)

9. There are 150 fruits on a market stall.
54 are oranges and 72 are apples and the rest are pears.
What percentage of the fruit are pears?
You must show your calculations. 015)
(2 Points)
Answer:
24%
Step-by-step explanation:
150 = 54 + 72 = 126 + 24 = 150
24/100 = 24%
Ahhh...first we need to find out the percentage of the oranges+the apples. then take it away from 100%.
I did a bit of tinkering and figured out that the orange percentage is 36% of it.
([tex]\frac{150}{54} =\frac{75}{27} =36%[/tex]%)
That means that the apples are 48% and the pears are 100-(36+48)=100-84=16%
