Answer:
<h2>100f = 27.272727...</h2>
Step-by-step explanation:
f = 0.272727...
100f = (100)(0.272727...)
100f = 27.272727...
Answer:
y=21.14
Step-by-step explanation:
x=6 because after 6 weeks
y= 3.27(6)+ 1.52
y=19.62 + 1.52
y=21.14
about 117 hours bc there are about 52 weeks in a year. And one week of 3 lessons is 2 (1/4)hrs. And 2(1/4) × 52 = 117 hrs
Answer:180 adults were admitted.
Step-by-step explanation:
Let x represent the number of children that were admitted into the park.
Let y represent the number of adults that were admitted into the park.
The admission fee at the amusement park is $1.50 for children and $4 for adults.
The admission fees collected totaled 1,014.00 dollars. This means that
1.5x + 4y = 1014 - - - - - - - - - -1
On a certain day, 376 people entered the park. This means that
x + y = 376
Substituting x = 376 - y into equation 1, it becomes
1.5(376 - y) + 4y = 1014
564 - 1.5y + 4y = 1014
- 1.5y + 4y = 1014 - 564
2.5y = 450
y = 450/2.5 = 180
Substituting y = 180 into x = 376 - y, it becomes
x = 376 - 180 = 196
Let x represent length of the stringer of the staircase.
We have been given that a builder makes staircases where each step is 29 cm long and rises 18 cm so people don't trip. Every staircase has a stringer - a diagonal support connecting all the steps. We are asked to find the length of the stringer of the staircase.
The length of the stringer of the staircase will be equal to diagonal of right triangle with two legs 29 cm and 18 cm.
Using Pythagoras theorem, we will get:
Now we will take square root of both sides of equation.
Since length cannot be negative, therefore, the length of the stringer of the staircase would be approximately 34.13 cm.
