Answer:
12.5%
Step-by-step explanation:
The question stated that 4 of her teeths have fillings out of her 32 teeth. From this info, we can represent 4 and 32 in fraction form; we can write it as 4/32. Now all you have to do is write 4/32 as a fraction. Divide 4 by 32 = 0.125. Multiply 0.125 by 100 to get 12.5%. Therefore, the answer is 12.5%.
Hope this helps!
Can you mark me brainliest pls? (Only if you want, I won’t mind if you don’t)
Answer:
12.5%
Step-by-step explanation:
There are two ways to go about this:
One way...Set up a proportion
4/32 = x/100
You know that 32 is basically 100% and you are trying to figure out the missing percentage which is represented by "x"
All you have to do once you set up this proportion is to cross multiply...
32 · x = 32x
4 · 100 = 400
and you are left with:
32x = 400
Divide both sides to isolate "x"
x = 12.5
Thus, your answer would be 12.5%
Second Way...
You can divide 4 by 32.
4 ÷ 32 = 0.125
Then multiply by 100 to get the percent
0.125 · 100 = 12.5
And you get 12.5%
Hope this helps!!! Let me know if you have any further questions :)

{put the given value of j and k in the given equation.. and solve ....}
Answer:
0.45
Step-by-step explanation:
This question is asking you to find the value of the equation when j = -4 and when k = -0.7. To do this, we must substitute j with -4 and k with -0.7:
(-4 * -0.7 - 1) / -4
= (2.8 - 1) / 4
= (1.8) / 4
= 0.45

150/120015/1201/8The shorter leg of a right triangle is 14 feet less than the other leg. Find the length of the two legs if the hypotenuse is 34 feet.
Answer:
side a = 30 feet long.and side b = 30-14 = 16 feet long.
Step-by-step explanation:
Right triangle, with sides a, b=a-14 and h=34
By Pythagorean rule, h2 = 342 = a2 + b2 = a2 + (a-14)2 ==> a2 + a2 - 28a + 196
Simplify to get 1156 = 2a2 - 28a + 196
Subtract 1156 from both sides to get 2a2 - 28a - 960 = 0
Divide all terms by 2: a2 -14a - 480 = 0
Use quadratic equation to find that a = 30 or a = -16.
a = -16 will not work.
Therefore side a = 30 feet long.and side b = 30-14 = 16 feet long.
Check: 302 + 162 = 900+256=1156. SQRT(1156) = 34 feet, the given hypotenuse.Right triangle, with sides a, b=a-14 and h=34
By Pythagorean rule, h2 = 342 = a2 + b2 = a2 + (a-14)2 ==> a2 + a2 - 28a + 196
Simplify to get 1156 = 2a2 - 28a + 196
Subtract 1156 from both sides to get 2a2 - 28a - 960 = 0
Divide all terms by 2: a2 -14a - 480 = 0
Use quadratic equation to find that a = 30 or a = -16.
a = -16 will not work.
Therefore side a = 30 feet long.and side b = 30-14 = 16 feet long.
Check: 302 + 162 = 900+256=1156. SQRT(1156) = 34 feet, the given hypotenuse.
The side length of the other sides is 30 feet and 16 feet if the shorter leg of a right triangle is 14 feet less than the other leg.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
It is given that:
The shorter leg of a right triangle is 14 feet less than the other leg.
From the Pythagoras theorem:
hypotenuse² = perpendicula² + base²
perpendicular = base - 14
34² = (base - 14)² + base²
34² = base² - 28base + 196 + base²
2base² - 28base - 960 = 0
base = 30, -16
side length cannot be negative
base = 30 feet
The length of another leg:
perpendicular = 30 - 14 = 16 feet
Thus, the side length of the other sides is 30 feet and 16 feet if the shorter leg of a right triangle is 14 feet less than the other leg.

x > -2Luisa took a job in which her salary can be modeled by the exponential function y = 36,000(1.025)^x, where x is the number of years after she is hired. Damon took a job with a starting salary of $38,500 and yearly raises of $800. Pick EACH correct statement about the scenario.
[] The difference in the starting salaries is $1,600.
[] The difference in the starting salaries is $2,500.
[] The difference in the starting salaries is $2,000.
[] Luisa will make more money in the first 8 years.
[] Damon will make more money in the first 8 years.
[] They will make the same amount of money in the first 8 years.
Answer:
B and D are the correct answer
Step-by-step explanation:
I took the test
The difference in the starting salaries is $2,500 and Luisa will make more money in the first 8 years thus (B) and (D) are correct.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
Given salary of Luisa by function,
y = 36,000(1.025)^x
The starting salary of Luisa,
x = 0 → y = 36000(1.025)^0 = $36000
Starting salary Damon = $38500
Difference = 38500 - 36000 = $2500
Amount of money that Luisa make in first 8 years ⇒
36,000(1.025)¹ + 36,000(1.025)² + ...up to 8 times
Amount of money that Damon makes in first 8 years ⇒
38500 + (38500 + 800) + (38500 + 2 × 800) + ...up to 8 times.
The rate of increment of Luisa > Damon
Hence "The difference in the starting salaries is $2,500 and Luisa will make more money in the first 8 years".

The number of CRT and LCD monitors in a company are in the ratio 2:5. If the total number of monitors in the company is 49, how many of them are LCD monitors?
Answer:
35 LCD monitors.
Step-by-step explanation:
The ratio is 2:5, which means the total amount of parts is 7 (2 + 5 = 7).
There are 49 monitors in all. Divide 49 with 7:
49/7 = 7
Each part has 7 monitors within. Remember, there are 5 parts of LCD monitors compared to 2 CRT monitors. Multiply 7 with 5:
7 x 5 = 35.
There are 35 LCD monitors, and 14 CRT monitors.

Answer:

A point estimate of the percentage of defectives in all manufactured bulbs is the Sample proportion.
How to find a point estimate of a proportion?
p'= x / n where x is the number of successes and n is the sample size. The variable p is the sample ratio and serves as a point estimate of the true ratio of the population.
Point estimation for population parameters is a single value for statistics. For example, the sample mean x is a point estimate of the population mean μ. Similarly, the sample ratio p is a point estimate of the population ratio P.
The average point estimate for the population is obtained by calculating the average of the samples taken from the population. The average calculation is the sum of all samples divided by the number of values.

x+4, what is the
length of the longest
side ?
Answer:
The longest side is 16 cm
Step-by-step explanation:
[tex]x + (x + 2) + (x + 4) = 42cm \\ x + x + 2 + x + 4 = 42cm \\ 3x + 6 = 42cm \\ 3x = 36cm \\ x = 12[/tex]
check and finish
[tex]12 + (12 + 2) + (12 + 4) = 42cm \\ 12 + 12 + 12 + 6 = 42 cm\\ 36 + 6 = 42cm \\ 42cm = 42cm[/tex]
