Answer:
10 hours
Step-by-step explanation:
We can convert the speed to km/h, and to do this, you simply have to find the amount Kevin rides in 1 hour. So,
24/2 = x/1
x = 12
So, now we see that Kevin rides at approximately 12 kmph. Now, instead of finding the distance, we need to find the hour at 120 km.
12/1 = 120/x
x = 10
Let x2+8x=7 .
What values make an equivalent number sentence after completing the square?
Enter your answers in the boxes.
x2+8x+ ? = ?
Answer:
x²+8x+16=24
Step-by-step explanation:
x²+8x=7 (+16)
x²+8x+16=7+16=24
(x+4)²=24
The values to be entered in the boxes are 16 and 23.
Given the equation is [tex]x^2[/tex]+8x=7
To complete the square for the equation [tex]x^2[/tex] + 8x = 7, we need to add a constant term on both sides of the equation to create a perfect square trinomial on the left side.
First, take half of the coefficient of the x-term (8) and square it:
[tex](8/2)^2[/tex] = 16
Now, add 16 to both sides of the equation:
[tex]x^2[/tex] + 8x + 16 = 7 + 16
Simplifying:
[tex]x^2[/tex] + 8x + 16 = 23
Therefore, the equivalent number sentence after completing the square is [tex]x^2[/tex] + 8x + 16 = 23
The values to be entered in the boxes are 16 and 23.
Hence, [tex]x^2[/tex] + 8x + 16 = 23.

A section of a deck is shaped like a trapezoid. For this section, the length of one base is 65 feet, and the length of the other base is 44 feet. The height is 30 feet. What is the area of this section of the deck? The area for the section of the deck is ft2.
Answer:
1635 feets²
Step-by-step explanation:
The Area of a trapezoid is given as :
1/2 (a +b)h
Where ;
a and b are the base of the trapezoid
h = height
From the question :
a = 65 feets
b = 44 feets
h = 30 feets
Area, A = 1/2(65 + 44) * 30
A = 1/2 (109) * 30
A = 1635 feets²
find the measurement indicated in the parallelogram
Answer:
m(∠W) = 114°
Step-by-step explanation:
By the property of a parallelogram,
"Opposite angles of a parallelogram are equal in measure"
By this property,
m(∠W) = m(∠U)
9x + 15 = 4 + 10x
15 - 4 = 10x - 9x
x = 11
Therefore, m(∠W) = 9x + 15
= 9(11) + 15
= 99 + 15
= 114°
Measure of angle W is 114°.
The function g(x) represents the amount of money in a savings account x years after it is opened.

A.
The initial balance of the account was $5,000.
B.
Between nine and ten years after opening the account, the balance shrank by $5,000.
C.
Between nine and ten years after opening the account, the balance grew by $5,000.
D.
Ten years after opening the account, the balance was $5,000.
Answer:
C
Step-by-step explanation:
Between nine and ten years after opening the account, the balance grew by $5,000.
Between nine and ten years after opening the account, the balance grew by $5,000. The correct answer would be an option (C)
What is the function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
The function g(x) represents the amount of money in a savings account x years after it is opened.
The statement g(10) - g(9) = $5,000 represents the difference in the balance between 9 and 10 years after opening the account, and since the difference is positive, it means that the balance grew by $5,000.
Hence, the correct answer would be an option (C)

Two angles are vertical angles. If one of the angles measures 35º and the other measures (4x+3)º, which algebraic equation can be used to solve for the value of x?
35 + 4x + 3 = 180
35 + 4x + 3 = 90
35 = 4x + 3
None of these are correct
4x + 3 = 90
35 = 4x+3
If they're vertical then they're worth the same or equal. So 4x+3 is equal to 35 and then you solve for x from there.

Imagine this < as a alligater and itś eating the greater number!!
Answer:
C.) r ≥ 7
Step-by-step explanation:
1. Add 7 to each side to cancel it out and keep the sign the way it is to avoid confusion
3r - 7 ≥ 14
+ 7 +7
3r ≥ 21
2. Divide each side by 3 to get the variable alone
3r/3 = r
21/3 = 7
r ≥ 7
This means r is greater than or equal to 7, and it can also be written as 7 ≤ r
The length of a rectangle plus its width is 18 cm. The area is 80 sq cm. what are the length and width of the rectangle?
Answer:
80 units squared
Step-by-step explanation:
If two sides of a rectangle add up to 18cm and the area is 80 units squared then the length is 10cm, and the width is 8cm. If you add 10 and 8 together you get 18, and if you multiply those you get 80 units squared.
