Answer:
s = 268.27
Step-by-step explanation:
simplify: 75+19547-11s=16671
simplify more: 19622-11s=16671
subtract 19622 on both sides: -11s=-2951
divide both sides by -11: s=268.27

I need to know how to work fractions word problems like Leon's older brother is 4 3/4 feet tall. Leon is 1/3 foot shorter than his brother. How tall is Leon?
Answer:
4 5/12 feet tall
Step-by-step explanation:
Find the LCM first. The LCM is the lowest common multiple between the two denominators. The LCM in this problem is 12, so you multiply each fraction until the denominators equal 12
4 3/4 -> 4 9/12
1/3 -> 4/12
Now it's much easier to solve. 4 9/12 - 4/12 = 4 5/12 feet tall

ummm pls help (: pls
Answer:
Hence, first one will be 1/3 and second one will be 1/6
Step-by-step explanation:
1. Let the blank space be x then,
[tex]3 \frac{2}{3} + x = 4[/tex]
[tex]x = 4 - 3 \frac{2}{3} [/tex]
[tex]x = \frac{12 - 11}{3} [/tex]
[tex]x = \frac{1}{3} [/tex]
2. Let the blank be x then,
[tex]x + \frac{2}{3} = \frac{5}{6} [/tex]
[tex]x = \frac{5}{6} - \frac{2}{3} [/tex]
[tex]x = \frac{5 - 4}{6} [/tex]
[tex]x = \frac{1}{6} [/tex]

The distance from New York City to Riverhead is approximately 150 miles. On a map whose scale is 24mi= 2inch, what is the distance between the two locations in inches?
Answer:
12.5 inches
Step-by-step explanation:
To best find this answer, we should set up a proportion. Our first fraction is practically given to us in the problem, and would look like this:
[tex]\frac{2in}{24mi}[/tex]
Next, we need to set up our second fraction. An important thing to make sure of is that the 150 is on the same side as the 24 since they are both miles. Here is what the final equation should look like:
[tex]\frac{2in}{24mi} = \frac{x}{150mi}[/tex]
To solve, just cross multiply and divide! First, multiply 2 by 150, giving you 300. Next, just divide the 300 by the remaining 24, giving you a final answer of 12.5 inches. Here's what the final calculations look like:
2in X 150mi = 300
300 / 24mi = 12.5in
Answer:
12.5 inches is your answer

TAN: 45/28
SIN: 45/53
COS: 28/53
sin(x°) = opposite/hypotenuse
cos(x°) = adjacent/hypotenuse
tan(x°) = opposite/adjacent
x is any degree measure.
Hence option C (45/28) is correct
What are trigonometric rations?
Sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec) are the six trigonometric ratios (sec). Trigonometry is the branch of mathematics concerned with the sides and angles of a right-angled triangle in geometry. As a result, trig ratios are assessed in terms of sides and angles.

Answer: 435 or 17.4
Step-by-step explanation:
A study is done by a community group in two neighboring colleges to determine which college graduates students with more math classes. College A samples 11 graduates. Their average is 4 math classes with a standard deviation of 1.5 math classes. College B samples 9 graduates. Their average is 3.5 math classes with a standard deviation of 1 math class. The community group believes that a student who graduates from college A has taken more math classes, on the average. Test at a 1% significance level.
A. Is this a test of two means or two proportions? Are the populations dependent or independent?
B. Are the populations' standard deviations known or not?
C. Which distribution is to be used?
D. What is random variable?
E. Hypothesis
F. Test is two tailed or one tail
G. Test value=_____.
H. Use P-value method) to reach to the conclusion.
Answer:
A) It is a test of two proportions and the populations are independent of each other
B) The population standard deviations are known : For college A the standard deviation is = 1.5 while for College B population the standard deviation is 1
C) The distribution to be used is 1 distribution
D) The Random variable is the size of the community group
E) Hypothesis : H0 : u1 = u2 . Ha : u1 > u2
F) Test is one tailed
G) Test Value > significance level
F) when; P value > significance level ( 0.01 ) we do accept Null hypothesis
when ; P value < significance level ( 0.01 ) we reject Null hypothesis
Step-by-step explanation:
College A :
sample size = 11
x ( mean ) value = 4
std = 1.5
College B :
sample size = 9
x ( mean value ) = 3.5
std = 1
A) It is a test of two proportions and the populations are independent of each other
B) The population standard deviations are known : For college A the standard deviation is = 1.5 while for College B population the standard deviation is 1
C) The distribution to be used is 1 distribution
D) The Random variable is the size of the community group
