Charles correctly answered 23 questions on a test receiving a grade of 92% how many questions where on the test
Answer:
25
Step-by-step explanation:
Cross multiply
23/x=92/100
x=25
There were approximately 25 questions on the test.
To determine the number of questions on the test, we can set up a proportion based on Charles' correct answers and the grade received.
Let x be the total number of questions on the test.
We can set up the proportion:
23 (Charles' correct answers) / x (total number of questions) = 92% (grade as a decimal: 0.92)
This can be written as:
23 / x = 0.92
To solve for x, we can multiply both sides of the equation by x:
23 = 0.92 * x
Dividing both sides by 0.92:
23 / 0.92 = x
x ≈ 25
Therefore, there were approximately 25 questions on the test.

NO LINKS ACCEPTED -The robot factory is a learning center where children can build robots. The project fee per visit is $15 and each hour of time (x) at the factory costs $4. Jesse goes to the robot factory one afternoon and was charged $40 for the visit. Write an equation that models this situation where X is the number of hours Jesse stands at the robot factory
Answer:
15 + 4x = 40
Step-by-step explanation:
To construct this equation, we'll list all the values we will include first.
The total fee equals $40, so we'll put 40 on one side of the equation.
On the other side, we have to put the values that make up the total. The fee is made with the project cost plus the hourly rate. The first part of this is the beginning cost, $15. Added to this is the hourly cost, $4, times the number of hours spent. So, the other side of the equation is 15 (the starting cost) plus 4 (the rate) times x (the unknown number of hours).
So, our equation is 15 + 4x = 40.

Two stakes are holding a small blimp in place. Stake A measures
an angle of elevation of 49° and Stake B measures an angle of
elevation of 58º. If the string attached to Stake A has a length of
148 feet, what is the length of the string attached to Stake B?
Answer: 131.7 ft
Step-by-step explanation: use 148 as side measure b, then solve for measure of side a
with two given angles and one given side, use law of sines.
a = b•sin(A)/sin(B) = 131.71071
c = b•sin(C)/sin(B) = 166.89278
if you want to find angle measures:
180-A-B
180-49-58=73
C=73
The length of the string attached to stake B is 166.3 feet.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
An angle of elevation of stake A = 49°
The length of the string attached to stake A,a = 148 feet
An angle of elevation of stake B = 58°
Let the length of the string attached to stake B be b.
Then by law of sines,
[tex]\frac{Sine A}{a}=\frac{Sine B}{b}[/tex]
On substituting the above values,
⇒ [tex]\frac{Sine 49}{148}=\frac{Sine 58}{b}[/tex]
⇒ [tex]b=\frac{(Sine 58)(148)}{Sine49}[/tex]
⇒ [tex]b=\frac{(0.8480)(148)}{0.7547}[/tex]
⇒ [tex]b=166.29[/tex] ≈ [tex]166.3[/tex]
Hence we can conclude that the length of the string attached to stake B is 166.3 feet.

A computer originally priced at $850 is on sale for 15% off. What is the sale price of the computer?
Answer:
Sale price: $722.50
Step-by-step explanation:
Subtract 15% from 100%, obtaining 85%. The computer is sold for 85% off.
Converting this 85% to a mixed decimal, we get 0.85, and then we multiply the original price ($850) by this 0.85: 0.85($850) = $722.50

After 5 years, Marcel's account earned $900 in interest. If the interest rate (in decimal form) is 0.06, how much did Marcel initially invest?
Answer:
$3000
Step-by-step explanation:
I= PRT÷100
where,
I = interest = 900
T= 5
R/100 = 0.06
P = ?
I= PRT/100
900= P × 5 × 0.06
P = 900÷ 0.3
P= 3000
