One side of a triangle is 4 inches longer than the side that is the base of the triangle. the third side is 6 inches longer than the base. of the perimeter is 34 inches, find the length of each side.
Final answer:
The base of the triangle is 8 inches, one side is 12 inches (base + 4), and the other side is 14 inches (base + 6). Hence, the side lengths of the triangle are 8 inches, 12 inches, and 14 inches, with a total perimeter of 34 inches.
Explanation:
The question describes a triangle with sides of varying lengths relative to what is defined as the base of the triangle. To find the length of each side, we'll use algebra and the fact that the perimeter of the triangle is given as 34 inches.
Let's denote the base as b. According to the problem, one side is 4 inches longer than the base, which would be b + 4 inches. The third side is 6 inches longer than the base, which would be b + 6 inches. The perimeter of a triangle is the sum of all its sides, so we have:
b + (b + 4) + (b + 6) = 34
Combining like terms, we get:
3b + 10 = 34
Subtracting 10 from both sides gives us:
3b = 24
Dividing by 3 gives us the length of the base:
b = 8 inches
Now, we can find the lengths of the other two sides:
b + 4 inches is 12 inches and b + 6 inches is 14 inches.
So, the lengths of the sides of the triangle are 8 inches, 12 inches, and 14 inches.
A has $32 more than B, and B has five times as much money as C. If C has d dollars, how much does A have? Answer:
A = B+32
B = 5C
A = 5C+32
C has d dollars so replace d for c
A = 5d+32

Let x represent the number of long-sleeved shirts. Let y represent the number of short-sleeved shirts.
Which inequalities are among the constraints for this situation?
Select each correct answer.
⋅ 15x + 10y ≥ 20
⋅ x + y ≤ 250
⋅ x + y ≥ 20
⋅ 15x + 10y ≥ 250

A soccer player who is 27 feet from a goal attempted to kick the ball in into the goal. the flight of the ball is modeled by a parabola. the ball reached a maximum height of 10 feet when it was 15 feet from the soccer player. the goal has a height of 8 feet. will the soccer ball land in the goal?
Answer:
The ball will land inside the goal.
Step-by-step explanation:
Given : The flight of the ball is modeled by a parabola.
To find : Will the soccer ball land in the goal?
Solution :
Let the equation of the parabola be,
[tex]y=a(x-h)^2+k[/tex]
Where, (h,k) are the vertex of the parabola,
According to question,
A soccer player who is 27 feet from a goal.
Let A be the point where player stand i.e, (27,0)
The height of the goal is 8 feet.
Let B be the point of height of goal i.e, (0,8)
The ball reached a maximum height of 10 feet when it was 15 feet from the soccer player.
The distance from goal to the distance 15 feet away from the player is
27-15=12 feet
Let C be the point with maximum height i.e, (12,10)
C is the vertex of the parabola and A is the point on the parabola.
Then, The equation of parabola is
[tex]y=a(x-12)^2+10[/tex]
Point A satisfy the equation,
[tex]0=a(27-12)^2+10[/tex]
[tex]0=a(15)^2+10[/tex]
[tex]a=-\frac{10}{225}[/tex]
Substitute back in equation,
[tex]y=-\frac{10}{225}(x-12)^2+10[/tex]
Now, we find the y-intercept of the equation i.e, x=0,
[tex]y=-\frac{10}{225}(0-12)^2+10[/tex]
[tex]y=-\frac{10}{225}(144)+10[/tex]
[tex]y=3.6[/tex]
If the y-intercept is greater than 8 then the ball will land outside the goal.
If the y-intercept is less than 8 then the ball will land inside the goal.
As 3.6<8
Therefore, The ball will land inside the goal.
Refer the attached figure below.
Final answer:
The soccer ball will not land in the goal due to its maximum height being above the height of the goal.
Explanation:
To determine if the soccer ball will land in the goal, we need to analyze its flight path. From the given information, we know that the ball reached a maximum height of 10 feet when it was 15 feet from the soccer player. This indicates that the ball's flight path is modeled by a downward-opening parabola.
Since the soccer player is 27 feet from the goal, we can consider the ball's horizontal distance from the player to the goal as the x-coordinate, and its height above the ground as the y-coordinate.
Based on the given information, the soccer ball will not land in the goal. The ball's maximum height is 10 feet, but the goal has a height of 8 feet. This means that at any point along its flight path, the ball's height will be above the height of the goal.
Harriet earns the same amount of money each day. Her gross pay at the end of 7 work days is 35h + 56 dollars. Which expression represents her gross pay each day?
Answer:
Daily Payment = 5h+8
Step-by-step explanation:
Here we are given that in seven days the amount Harriet earned is given as
35h+56
It is also given that the amount earned each day is same.
We have to determine the amount earned each day. Total number of days is 7 . Hence in order to find the daily earning we divide the total earning by 7
Daily earning =
[tex]E=\frac{35h+56}{7}\\E=\frac{7(5h+8)}{7}\\E=5h+8[/tex]
Hence answer is 5h+8

Write log3 6 as a logarithm of base 2
a. log base 2 of 3 over log base 2 of 6
b. log base 2 of 6 over log base 2 of 3
c. log base 3 of 2 over log base 6 of 2
d. log base 6 of 2 over log base 3 of 2
Final answer:
The expression log3 6 can be converted to a logarithm of base 2 using the change of base formula, which results in log2 6 / log2 3. So the correct option is b.
Explanation:
The student asked how to express log3 6 as a logarithm with a base of 2. To perform this conversion, we can use the change of base formula, which states that logab = logcb / logca for any positive numbers a, b, and c, where a and c are not equal to 1. In this formula, 'c' can be any base, but in our case, we will use base 2 since that's what the question requires.
So, by applying the change of base formula, we can write:
log₃6 = log₂6 / log₂3Therefore, the correct option that represents log3 6 as a logarithm of base 2 is:
(b) log₂6 / log₂3What what are the rules for addition and subtraction with numbers in scientific notation?
