Write an equation represents the number of bracelets b Carly will have if she works t hours making bracelets in the next 2 weeks and averages one bracelet every 2 hours
Find the measures of the angles of a right triangle where one of the two acute angles measures 5 times the other
Answer:
Since it is a right angle, you know that the angle measures 90 degrees. Since one acute angle measures 5x (times) the other, you would set it up in equation format as 5x + x = 90.
5x + x = 6x, so
6x = 90
you divide both both sides by 6 (90/6) = 15
To find the measure of the angle that is 5x (times) the other, you do 5(15) = 75 degrees and the other angle is 15 degrees, which adds up to 90 degrees.

Step-by-step explanation:
Matthew can buy an 8-ounce jar of salsa for $2.85 or a 15-ounce jar of salsa for $5.65. Which jar is the best buy and what is the unit rate?
Answer:
The $2.85 jar is the better buy.
Step-by-step explanation:
Start by finding the two separate unit rates. Then compare them:
$2.85
---------- = $0.36/oz
8 oz
$5.65.
----------- = $0.38/oz
15 oz
The $2.85 jar is the better buy, as its unit cost is lower.
Final answer:
The 8-ounce jar of salsa at $0.35625 per ounce is the better buy compared to the 15-ounce jar at $0.37667 per ounce.
Explanation:
The student wants to determine which jar of salsa provides the best value in terms of cost per ounce. To find the unit rate, we need to divide the price of each jar by the number of ounces it contains.
For the 8-ounce jar of salsa:
Unit rate = $2.85 / 8 oz = $0.35625 per ounce
For the 15-ounce jar of salsa:
Unit rate = $5.65 / 15 oz = $0.37667 per ounce
Comparing the unit rates, the 8-ounce jar of salsa has a lower unit rate, making it the better buy.

A Car Travels m miles in t hours express its average speed algebraically
Answer:
speed = [tex]\frac{m}{t}[/tex]
Step-by-step explanation:
using the formula that relates distance/ speed/ time
distance = speed × time
hence speed = [tex]\frac{distance}{time}[/tex] = [tex]\frac{m}{t}[/tex]
Final answer:
The average speed is calculated by dividing the total distance traveled by the total time taken. In algebraic form for a car traveling m miles in t hours, the average speed is V_avg = m / t.
Explanation:
To express the average speed algebraically, we can use the formula for average speed which is the distance traveled divided by the time of travel. In algebraic terms, if a car travels m miles in t hours, the average speed would be represented as:
Vavg = m / t
Here, Vavg represents the average speed, m is the total distance in miles, and t is the time taken in hours. To demonstrate this with an example, if a car travels 150 kilometers in 3.2 hours, its average speed is calculated by dividing 150 km by 3.2 h, which gives an average speed of 47 km/h.

find the angle of elevation of the sun if a building 100 feet tall casts a shadow 150 feet long.
The angle of elevation of the sun can be determined using trigonometry by finding the inverse tangent of the ratio of the building height to the shadow length, which is approximately 33.69 degrees.
To find this, we can use trigonometry, specifically the tangent function, which is the ratio of the opposite side over the adjacent side in a right-angled triangle. Here, the building height represents the opposite side, and the shadow length represents the adjacent side.
Using the formula tangent = opposite/adjacent, we have:
tangent(\(\theta\)) = 100 / 150tangent(\(\theta\)) = 2/3Now, we need to find the angle whose tangent is 2/3. By using a calculator or a trigonometry table, we find:
\(\theta\) = tan-1(2/3) \(\approx\) 33.69 degreesTherefore, the angle of elevation of the sun is approximately 33.69 degrees.

Rewrite the expression without using a negative exponent.
Simplify your answer as much as possible.
Answer:
[tex]\frac{n^4}{4}[/tex]
or
[tex]\frac{1}{4} n^4[/tex]
Step-by-step explanation:
The given expression is
[tex]\frac{1}{4n^{-4}}[/tex]
This is an exponential expression with a negative index in the denominator.
We can rewrite the expression so that it will be,
[tex]=\frac{1}{4}\times \frac{1}{n^{-4}}[/tex]
We now apply this property of indices. A negative index in the denominator becomes a positive index in the numerator.
[tex]\frac{1}{a^{-m}} =a^{m}[/tex]
When we apply this we get,
[tex]=\frac{1}{4}\times n^{4}[/tex]
We then simplify to obtain,
[tex]=\frac{1}{4}n^{4}[/tex]
Final answer:
To rewrite an expression without a negative exponent, take the reciprocal of the base with the positive exponent. Division of exponentials requires dividing coefficients and subtracting exponents of the same base. Eliminate negative exponents and simplify the expression to get the final result.
Explanation:
To rewrite an expression without a negative exponent, you simply take the reciprocal of the base and use the positive exponent. For example, seeking to rewrite x-n, you would transform it into 1/xn, moving the base x to the denominator and making the exponent positive.
Division of exponentials involves simplifying expressions by dividing the coefficients and subtracting exponents when the bases are the same. For instance, for expressions like am / an, the result would be am-n. In case there are numerical coefficients in front, divide those numbers directly. After simplifying, always check whether the answer makes sense and is in the simplest form.
Working with negative exponents, it's crucial to eliminate terms that result in a more straightforward expression and confirm that no negative exponents remain in the final answer, ensuring it is in its acceptable form.
What is n in the equation -5(1+6n)=5n-5?
Answer:
0 is your answer
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Remember to follow PEMDAS.
First, distribute -5 to all terms within the parenthesis
-5(1 + 6n) = (-5)(1) + (-5)(6n) = -5 - 30n
-30n - 5 = 5n - 5
Isolate the variable, n. Subtract 5n and add 5 to both sides
-30n (-5n) - 5 (+5) = 5n (-5n) - 5 (+5)
-30n - 5n = -5 + 5
-35n = 0
Isolate the n, Divide -35 from both sides
(-35n)/-35 = (0)/-35
n = 0

Number 6: Answer B
Step-by-step explanation:
5) The percent of decrease from 57 to 19 is:B. 66.7%
6) The percent of markup is: D. 35%
How to find the percentage?6) To find the percent of decrease from 57 to 19, we can use the formula:
percent decrease = (original value - new value) / original value x 100%
Substituting the given values, we get:
percent decrease = (57 - 19) / 57 x 100%
percent decrease = 38 / 57 x 100%
percent decrease = 0.6667 x 100%
percent decrease = 66.7%
Therefore, the percent of decrease from 57 to 19 is 66.7%. The answer is option B.
6) To find the percent of markup, we can use the formula:
percent markup = (selling price - cost) / cost x 100%
Substituting the given values, we get:
percent markup = (184.70 - 136.50) / 136.50 x 100%
percent markup = 48.20 / 136.50 x 100%
percent markup = 0.353 x 100%
percent markup = 35.3%
Therefore, the percent of markup is 35%. The answer is option D.

The system of equations x+y=154 and x+4y=10, can be solved by substitution method giving the solution x = 202 and y = -48.
Explanation:This question is similar to other problems in algebra where you are given a system of equations. In this case, you have the equations x+y=154 and x+4y=10. We will solve this problem using substitution.
First, let's isolate x in the first equation: x = 154 - y.
Next, we will substitute (154-y) for x in the second equation: (154 - y) + 4y = 10. Simplifying this equation, we get 3y = -144, so y = -48.
Substitute back y = -48 into the first equation, we have x + (-48) = 154, which means x = 202.
So, the solution of the system is: x = 202, y = -48.

The number of chairs in a row continues to increase by 6 with each additional row. a) write the first 5 numbers of this sequence b)what is the explicit tilde for the number of seats in n rows c)use the rule you wrote in 1b to determine which row has 103 seats. SHOW ALL WORK
A) 1st Row = 31 seats
2nd row = 37 seats
3rd row = 37+6 = 43 seats
4th row = 43+6 = 49 seats
5th row = 49+6 = 55 seats
B) The formula for finding the number of seats in any row number is:
Number of seats in nth row = 31 + (n-1) *6
C) To find the row with 103 seats, set the equation in B to equal 103 and solve for n:
103 = 31 + (n-1)*6
Subtract 31 from each side:
72 = (n-1)*6
Divide both sides by 6:
12 = n-1
add 1 to each side:
n = 13
The 13th row has 103 seats.
