Answer:
2/3 = 16/24
5/8 = 15/24
Step-by-step explanation:
2/3= 16/24
5/8= 15/24
because if you multiply across [tex]\frac{2}{3}[/tex] by [tex]\frac{8}{8}[/tex] equal [tex]\frac{16}{24}[/tex]
and if you multiply across [tex]\frac{5}{8}[/tex] by [tex]\frac{3}{3}[/tex] equal [tex]\frac{14}{24}[/tex]
Solve the inequality: a - 4 <10
Α. α >14
B. a < 14
C. a <-14
D. a > 6
E. a<6
HELP!!
==================================================
Explanation:
Add 4 to both sides
a-4 < 10
a-4+4 < 10+4
a < 14
The reason why we add 4 to both sides is to undo the "minus 4" that's happening to the variable.

What is the smallest number that can be divided by 3,9,12 without a remainder
Answer:
36
Step-by-step explanation:
Factor each into prime numbers
3 = 3
9 = 3 * 3
12 = 2 * 2 * 3
least common multiple
product of greatest number of different primes in any of the numbers
3 * 3 * 2 * 2
36
Answer:
LCM = 36
Step-by-step explanation:
Basically you want to find LCM which is the Least Common Multiple. This is the process of coming up with the smallest positive multiple that is common to two or more numbers.
Look up how to solve using cake ladder method. Basically you are going to list all numbers and use the same number to divide them in whole number without remainder. You do this until you encounter a point where you cannot further divide without remainder. Then you multiply the left most column and last row.
I have listed the process below and answer is 36 (multiply the left most column and last row. )

Answer: Soup B
Step-by-step explanation: You can find the common denominator for each ratio, and then compare.
Soup A : 3 grams of sodium for 13 cups of soup,
therefore: 30 grams of sodium for 130 cups of soup
Soup B: 9 grams of sodium for 10 cups of soup,
therefore: 117 grams of sodium for 130 cups of soup
So, Soup B has more sodium per cup.
If you want to figure out the amount of sodium for 1 cup, divide the amount of sodium by the amount of soup. Hope this helped!

Madeline says that the two expressions 4(5 + x) and 20+ x equivalent.
(a)
Is Madeline correct?
A
Yes
B
No
Answer:
B No
Step-by-step explanation:
4(5 + x)
To simplify the expression, we must use the distributive property. We need to multiply 4 by the each of the two terms inside the parentheses.
4(5 + x) = 4 × 5 + 4 × x = 20 + 4x
20 + 4x is equivalent to 4(5 + x).
20 + x is not equivalent to 20 + 4x, so 20 + x is incorrect.

What is the missing side length in the triangle below?
Answer:
Step-by-step explanation:
pythagoras theorem
a^2+b^2=c^2
21^2+b^2=29^2
441+b^2=841
b^2=841-441
b^2=400
b=[tex]\sqrt{400[/tex]
b=20
therefore the length of a missing side is 20.
Answer:
20
Step-by-step explanation:
Use Pythagorean theorem. A^2+B^2=C^2
29 is the hypotenuse.
21^2+x^2=29^2

Find the area of a regular heptagon with a side length of 14 units. Use 2 decimal places
in your calculations.
Answer:
Area of heptagon = 712.26 square units
Step-by-step explanation:
Given the following data;
Side length = 14 units
A heptagon is a polygon with seven sides.
Mathematically, the area of a heptagon is given by the formula;
Area of heptagon = 3.634a²
Where;
a represents the side length.
Area of heptagon = 3.634 * 14²
Area of heptagon = 3.634 * 196
Area of heptagon = 712.26 square units
The distribution of student scores on the quantitative section of the SATs have an approximately normal distribution with a mean score of 501 points, and a standard deviation of 85 points. If you randomly select one student who has taken the SAT, what is the probability that the student will have scored greater than 600 points on the quantitative section of the SATs
Answer:
0.122 = 12.2% probability that the student will have scored greater than 600 points on the quantitative section of the SATs.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean score of 501 points, and a standard deviation of 85 points.
This means that [tex]\mu = 501, \sigma = 85[/tex]
What is the probability that the student will have scored greater than 600 points on the quantitative section of the SATs?
This is 1 subtracted by the p-value of Z when X = 600. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{600 - 501}{85}[/tex]
[tex]Z = 1.165[/tex]
[tex]Z = 1.165[/tex] has a p-value of 0.878.
1 - 0.878 = 0.122
0.122 = 12.2% probability that the student will have scored greater than 600 points on the quantitative section of the SATs.

The value of y-intercept of the given function is (0,0).
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Since, We know that;
When a function intersects the y-axis then the point of intersection is called y-intercept of the function,
Also, for y-intercept x = 0.
That is, if f(x) is the function then its y-intercept is (0, f(0) )
By the given table for x = 0, f(x) = 0
Hence, tWhen a function intersects the y-axis then the point of intersection is called y-intercept of the function,
Also, for y-intercept x = 0.
That is, if f(x) is the function then its y-intercept is (0, f(0) )
By the given table for x = 0, f(x) = 0
Hence, the y-intercept of the given function is (0,0),
Thus, The value of y-intercept of the given function is (0,0).

6. Yenni bought some apple pies for $13 and had some money left. If she
buys 1 more apple
pie, she would have $0.20 left. If she decided to buy 3
more apple pies, she would be short of $1.80.
(a) How many apple pies did she buy with $13?
(b) How much money did Yenni have at first?
Answer:
A) Since each apple pie costs $ 1, with $ 13 Yenni bought 13 apple pies.
B) Yenni had $ 14.20 at the beginning.
Step-by-step explanation:
Since Yenni bought some apple pies for $ 13 and had some money left, and if she buys 1 more apple pie, she would have $ 0.20 left, while if she decided to buy 3 more apple pies, she would be short of $ 1.80, for To determine how many apple pies did she buy with $ 13, and how much money did Yenni have at first, the following calculations must be performed:
0.20 - (-1.80) = X
0.20 + 1.80 = X
2 = X
2/2 = 1
Therefore, since each apple pie costs $ 1, with $ 13 Yenni bought 13 apple pies.
13 + 1 + 0.20 = 14.20
14.20 - 13 = 1.20
In turn, Yenni had $ 14.20 at the beginning.

Which equation represents the line that passes through the points (-4, 0) and (0, 6)
Answer:
y = 1.5x + 6
Step-by-step explanation:
Given the following data;
Points on the x-axis (x1, x2) = (-4, 0)
Points on the y-axis (y1, y2) = (0, 6)
To find the equation of line;
First of all, we would determine the slope of the line.
Mathematically, slope is given by the formula;
[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]
[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]
Substituting into the equation, we have;
[tex] Slope, m = \frac {6 - 0}{0 - (-4)} [/tex]
[tex] Slope, m = \frac {6}{4} [/tex]
Slope, m = 1.5
To find the equation of line, we would use the following formula;
y - y1 = m(x - x1)
Substituting into the formula, we have;
y - 0 = 1.5(x - (-4))
y = 1.5x + 6

If the scores per round of golfers on the PGA tour are approximately normally distributed with mean 69.3 and standard deviation 2.58, what is the probability that a randomly chosen golfer's score is below 70 strokes
Answer:
0.6069
Step-by-step explanation:
Given an approximately normal distribution:
Z = (x - mean) / standard deviation
Mean = 69.3 ; Standard deviation = 2.58
For :
P(x < 70)
Z = (70 - 69.3) / 2.58
Z = 0.7 / 2.58
Z = 0.2713
P(Z < 0.2713) = 0.6069

Cindy buys a boat for $15,000. This will be a simple interest
loan at 5.5% for 10 years. What is the interest on the loan?
Answer:
$8,250
Step-by-step explanation:
I = prt
I = ($15,000)(0.055)(10)
I = $8,250
The interest on the loan is $8250.00
The formula for determining simple interest is : loan amount x time x interest rate
Loan is the amount of money that Cindy borrowed. It is $15,000
interest rate = 5.5%
Time is the length of period of the loan. This is 10 years
