Answer:
Step-by-step explanation:
yes, as below
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 :)

Use the Pythagorean Theorem to find the missing length and then round the result to the nearest tenth. a = 6, b = 3, C =
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

The floor plan of a proposed auditorium shows a stage that measures 1.75 inches in width . The scale of the floor plan is 1 in = 18ft . What is the width of the proposed stage ?
Answer:
31.5
Step-by-step explanation:
so if they say that every inch is realy 18 ft and u have 1.75 inches then multiply 8 by 1.75 to get the width of the stage
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%

What is the value of x
?
Answer:
the value of x is 9
Step-by-step explanation:
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:
36
Step-by-step explanation:
3*4^(2) - (4*18)/(6)= 36
For each fraction, write an equivalent fraction that has a denominator of 36.
1. 5/12 2. 1/6 3. 7/9
Answer:
Step-by-step explanation:
1) 5/12
To make the denominator to 36, 12 should be multiplied by 3. As we are multiplying the denominator by 3, numerator also should multiplied by 3
[tex]\frac{5}{12}=\frac{5*3}{12*3}=\frac{15}{36}[/tex]
2) 1/6
[tex]\frac{1}{6}=\frac{1*6}{6*6}=\frac{6}{36}\\[/tex]
3) 7/9
[tex]\frac{7}{9}=\frac{7*4}{9*4}=\frac{28}{36}[/tex]

Answer:
5 porque 3 mas 2 es 5, 4 mas 1 es 5
What does that equal
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]
No Solutions 6−3+4x+1= x + One Solution 6−3+4x+1= x + Infinitely Many Solutions 6−3+4x+1= x +
Complete Question:
Complete each equation, so the statement about its solution is true.
No solutions:
6-3+4x+1= __x + __
One solution:
6-3+4x+1= __x + __
Infinitely many solutions:
6-3+4x+1 = __x + __
Answer:
[tex]4 + 4x = 4x + 3[/tex] --- No solution
[tex]4 + 4x = 3x + 2[/tex] --- One solution
[tex]4 + 4x = 4 + 4x[/tex] --- Infinitely Many solution
Step-by-step explanation:
Solving (a): No solutions
6-3+4x+1= __x + __
Collect like terms
6-3+1+4x= __x + __
4+4x= __x + __
To get no solution, the coefficient of x on both sides must be the same. However, the constant must be different.
So, we can equate the expression to:
[tex]4 + 4x = 4x + 3[/tex]
Solving (b): One solution
6-3+4x+1= __x + __
This gives (same as (a))
4+4x= __x + __
To get one solution, the coefficient of x on both sides must be different. The constant can have any value.
So, we can equate the expression to:
[tex]4 + 4x = 3x + 2[/tex]
Solving (c): Infinitely many solutions
6-3+4x+1= __x + __
This gives (same as (a))
4+4x= __x + __
To get infinitely many solutions, both sides of the equation must be equal.
So:
[tex]4 + 4x = 4 + 4x[/tex]
