Step-by-step explanation:
Steve and Stephanie both get weekly allowances. Steve receives $15 plus $1.25 for every hour he completes housework. Stephanie receives $5 for every hour she completes housework. Write the equation that represents the situation. Let h represent the number of hours. Solve the equation. How many hours of housework do they need to complete for their allowances to be equal?
Answers
Answer:
25
Step-by-step explanation:
Steve and Stephanie need to complete 4 hours of housework for their allowances to be equal.
What is equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
Let 'x' represents the Steve's weekly allowances and 'y' represents the Stephanie's weekly allowance.
Let h represent the number of hours.
Steve receives $15 plus $1.25 for every hour he completes housework.
So, we get an equation,
⇒ x = (1.25)h + 15
Stephanie receives $5 for every hour she completes housework.
So, we get an equation,
⇒ y = 5h
We need to find the number of hours of housework they need to complete for their allowances to be equal.
When their allowances are equal,
⇒ x = y
⇒ (1.25)h + 15 = 5h
⇒ 3.75 h = 15
⇒ h = 4 hours
Therefore, they need to complete 4 hours of housework for their allowances to be equal.

F(x) 3x^4-4x^2-3
Is this function odd?
Answers
Answer:
No.
Step-by-step explanation:
f(x) = 3x^4-4x^2-3
If a function is odd then f(-x) = -f(x) for all values of x.
Here f(-x) = 3(-x)^4 - 4(-x)^2 - 3
= 3x^4 - 4x^2 - 3
So f(-x) = f(x) which makes it even.

What type of triangle can have one right angle? acute equilateral isosceles scalene asap plz
Answers
Answer:
answer: equilateral triangle
Step-by-step explanation:
the triangle that can have 1 right angle is A right isosceles triangle has a 90-degree angle and two 45-degree angles. This is the only right triangle that is an isosceles triangle.
Scalene is a type of triangle which can have one right angle.
A scalene triangle is a triangle in which all three sides and angles are different. This means that none of the sides or angles in a scalene triangle are equal to each other.
In the case of a triangle with one right angle, it means that one of the angles measures exactly 90 degrees, while the other two angles are different.
Additionally, since the angles are different, it follows that the lengths of the sides are also different, resulting in a scalene triangle.
Therefore, the correct answer is "scalene" for a triangle that can have one right angle.

Is − 379 in the sequence below? -5,-7,-9,-11,-13
PLEASE HELP ASAP
Answers
I hope this helps.
-379 is not in the sequence, the answer is NO, -379 is not in the sequence -5, -7, -9, -11, -13.
To determine if -379 is in the sequence -5, -7, -9, -11, -13, we need to check if it follows the pattern of the sequence.
The sequence appears to be decreasing by 2 at each step. Starting from -5 and subtracting 2 successively, we get:
-5, -7, -9, -11, -13, ...
To find out if -379 is in the sequence, we continue subtracting 2 from the last number in the sequence (-13) until we reach -379:
-13 - 2 = -15
-15 - 2 = -17
-17 - 2 = -19
...
(continue subtracting 2 until we reach -379)
Since -379 is not in the sequence, the answer is NO, -379 is not in the sequence -5, -7, -9, -11, -13.

Harry owes the bank money. To repay his debt, he paid \$150$150dollar sign, 150 back to the bank each month. After 101010 months, his remaining debt was \$6900$6900dollar sign, 6900.
Answers
$8,400
Explanation:
Amount repaid each month = $150
Number of Periods for which amount was paid = 10 months
Amount left after 10 months payment = $6900
The total amount paid = $150 × 10 = $1500
Amount left = $6900
Total debt amount:
(Total Amount left + total amount paid )
$(6900 + 1500)

Question is: Work of the bearing of Q from P.
Answers
Answer:
The bearing of Q from P is [tex]75^{o}[/tex].
Step-by-step explanation:
The diagram shows the locations of each point with respect to their bearings. As in bearing, angles are measured with the north axis taken as a reference point.
So that,
the bearing of Q from P would be the value of angle NPQ.
<NPQ = [tex]180^{o}[/tex] - <NQP (alternate angle principle)
= [tex]180^{o}[/tex] - [tex]105^{o}[/tex]
= [tex]75^{o}[/tex]
Thus, the bearing of Q from P is [tex]75^{o}[/tex].
Furthermore, the bearing of P from Q can be determined as;
= [tex]360^{0}[/tex] - [tex]105^{o}[/tex]
= [tex]255^{o}[/tex]
The bearing of P from Q is [tex]255^{o}[/tex].
