Answer:
The triangle is A = 48°, a = 32, B = 38.83°, b = 27, C = 93.17° and c = 42.99
Step-by-step explanation:
We have sine rule,
[tex]\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}[/tex]
Here given A = 48°, a = 32, b = 27
Substituting
[tex]\frac{32}{sin48}=\frac{27}{sinB}=\frac{c}{sinC}\\\\sinB=0.627\\\\B=38.83^0[/tex]
We have
A + B + C = 180°
48 + 38.83 + C = 180
C = 93.17°
Using sine rule again
[tex]\frac{32}{sin48}=\frac{c}{sin93.17}\\\\c=42.99[/tex]
So the triangle is A = 48°, a = 32, B = 38.83°, b = 27, C = 93.17° and c = 42.99

8.9 – 1.4x + (–6.5x) + 3.4
Answer:
12.3 – 7.9x
Step-by-step explanation:
the product of + and - is -
Therefore,
8.9 – 1.4x + (–6.5x) + 3.4
= 8.9 – 1.4x –6.5x + 3.4
collect like terms
= – 1.4x – 6.5x + 3.4 + 8.9
= –7.9x + 12.3
= 12.3 – 7.9x

Andy is trying to determine the correlation between the number of math homework assignments he completes and his test score. Which is the BEST estimate for the correlation coefficient of the data? A) r = 1.5 B) r = 0.5 C) r = 0.96 D) r = −0.90
Answer:
Option C
Step-by-step explanation:
It is really obvious that whenever the number of homework assignments he completes increases, his knowledge in the subject increases. This will increase automatically his test score in Maths.
Thus we can expect a perfect linear association between number of assignments done and his test score.
The correlation coefficient which is a measure of linear association between two variables always lies between -1 and +1.
Hence Option a cannot be correct since the value is greater than 1.
b) r=0.5 gives a positive but not very strong association. This is wrong as there is a strong association between the two variables
c) r=0.96 seems to be a correct answer as the positive and near to 1 r value confirms the linear strong positive association between the two variables.
D) r =-0.90 is wrong since there cannot be a negative association.
So only option right is option C

A cone is inscribed in a regular square pyramid. If the pyramid has a base edge of 6" and a slant height of 9", find the volume of the cone. 12√2 18√2 27
The volume of the cone inscribed in the pyramid, calculated using the formula for the volume of a cone and the Pythagorean theorem, is 18√2π cubic inches.
Explanation:In this question, we're asked to find the volume of the cone inscribed in a regular square pyramid. The volume V of a cone can be calculated using the formula V = 1/3 * pi * r^2 * h, where r is the radius of the base and h is the height of the cone. Since the cone is inscribed in the pyramid, its height and base radius would be the same as those of the pyramid.
However, the pyramid is a square pyramid with a base edge of 6 inches and a slant height of 9 inches. The height of the pyramid (and thus the cone) can be calculated using the Pythagorean theorem as √(9^2 - (6/2)^2), which is √(81 - 9) = √72 = 6√2.
The radius of the base of the cone is half of the base edge length of the pyramid, or 3 inches. So the volume of the cone is V = 1/3 * pi * 3^2 * 6√2 = 18√2π cubic inches.

Question:
Sherri has 23 pieces of jewelry to sell. She sells the bracelets for $2 and the necklaces for $3, and earns a total of $55. If the bracelets are represented by x and the necklaces are represented by y, which of the following systems of equations can be used to calculate the number of bracelets and necklaces sold?
Answer choices:
x + y = 23, 3x + 2y = 55
x + y = 55, 3x + 2y = 23
x + y = 23, 2x + 3y = 55
x + y = 55, 2x + 3y = 23,
Molly can either take her lunch or buy it at school. It cost $1.95 to buy lunch. If she wants to spend no more than $30 each month, how many lunches can she buy at most?
Final answer:
Molly can purchase a maximum of 15 school lunches per month with a budget of $30, considering each lunch costs $1.95.
Explanation:
The question asks how many school lunches Molly can buy if each lunch costs $1.95 and she wants to spend no more than $30 each month. To find out how many lunches Molly can buy, we divide her monthly budget by the cost of one lunch.
So, we perform the calculation: $30 ÷ $1.95 ≈ 15.38. Since Molly cannot buy a fraction of a lunch, we round down to the nearest whole number, which means Molly can buy 15 lunches at most in a month without exceeding her budget.

What do each of the variables in this equation (a,b,x) represent?
The exponential function, which means as you increase in x , y increases exponentially.
It is required to represent the variable.
What is Exponential functions?Exponential functions are patterns that get continuously multiplied by some number. It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.
Given that:
The standard form of an exponential growth or decay equation is
f(x) = a(b)^x
This is an exponential function, which means as you increase x , y increases exponentially. The initial amount is given by the value a , which is easy to see (just let x=0 and you have y=a left). The growth factor is the value b .
If you restrict b such that 0<b<1 , the function will decay (represented below) and if b>1 , the function will grow.
Therefore, the exponential function, which means as you increase in x , y increases exponentially.

Express the ratio of a's to n's in the word banana, in simplest form.
The ratio of A's to N's in the word BANANA is 2:1. This means that there are twice as many A's as there are N's in the word. Therefore, the correct answer is D: 2:1.
To find the ratio of A's to N's in the word BANANA, we need to count the number of A's and N's in the word.
1. Count the occurrences of A and N:
In the word BANANA, there are 3 A's and 1 N.
2. Express the ratio:
The ratio of A's to N's is 3:1.
3. Simplify the ratio:
To simplify the ratio, we can divide both parts by their greatest common divisor (GCD), which is 1 in this case, because 3 and 1 have no common divisor other than 1.
[tex]\[ \text{Ratio} = \frac{3}{1} = 3:1 \][/tex]
