We know that he weeds gardens for 15 hours, and mows lawns for x hours.
If he wants to earn $252 per month, we can express the following
Now, we solve for x
<h2>Hence, he has to mow lawns for 13 hours to earn at least $252.</h2>
Answer:
- width: 1.9 ft
- length: 2.3 ft
- height: 1.7 ft
Step-by-step explanation:
The volume of a rectilinear shape is given by ...
V = W·L·H . . . . . where W, L, and H represent width, length, and height
Filling in the given information, we want to find a solution to ...
7.4 = x(x +0.4)(x -0.2)
If we write ...
f(x) = x(x +0.4)(x -0.2)
Then we're looking for the value of x that satisfies ...
f(x) -7.4 = 0
The attached graph shows that value to be 1.897, about 1.9 (feet). Then the desired kennel dimensions are ...
- width: 1.9 ft
- length: 2.3 ft
- height: 1.7 ft
B should be the answer Hope this helps.
Answer: For part A, the formula for the employee's pay is <em><u>P</u></em>ay = hourly <em><u>r</u></em>ate times <em><u>h</u></em>ours . P = r × h The equation is P = 13h To find how many hours are required to earn a given amount, fill in given values and solve for the missing variable . 7800 = 13h h= 7800/13 600 hours needed.
For part B, the formula for this employee's pay is <em><u>P</u></em>ay = <u><em>B</em></u>onus + hourly <em><u>r</u></em>ate times <em><u>h</u></em>ours . P = b + rh
330 = 90 + r(24) 330 - 90 = 24r . 240 = 24r 240/24 = r . r = 10
The employee's pay rate is $10 per hour.
Try this solution:
according to the rule sin(90-y)=cos(y), it is possible to re-write the given equation:
sin(90-y)=cos53°, where 90-y=x.
Then substituting the value y=53° into the equation 90-y=x, it is possible to find the 'x': 90-53=37°.
answer: 37°
