How can you check that k ≥ 11 is the solution set to the inequality k + 14 ≥ 25?
Answer:
K= 11
Step-by-step explanation:
You solve for K by subtracting 14 by 25.
25-14= 11
When k is pluged into k[tex]\geq[/tex] 11 the statement is true because it is equal to 11.
When plugged into k+14[tex]\geq[/tex]25;
11+14 =25.
That statement is also true because 25 is equel to 25.

PLEASE HELP I WILL MARK YOU BRAINLIEST The function h(t)=- 16t^2 +92t describes the height of a model rocket. Use technology to graph the
function and answer the questions below. Round your answers to the nearest hundredths (3 points)
a. At what times is the model rocket at a height of 100 feet?
b. For how long is the rocket in the air?
Answer:
Step-by-step explanation:
100 = -16t^2 + 92t
16t^2-92t + 100 = 0
4t^2 - 23t + 25 = 0
t = [23 ±√(23^2-4(4)(25))]/[2(8)] ≈ 1.5, 4.3
The rocket has altitude of 100 ft at 1.5 sec and 4.3 sec.
:::::
0 = 16t^2-92t = t(16t-92)
t = 0, 5.75
Rocket is in the air for 5.75 seconds

Find the area of the trapezoid shown and choose the appropriate result
Answer:
B: 13.5 in^2
Step-by-step explanation:
The average length of this trapezoid is (4 in + 5 in)/2, or 4.5 in.
The height is 3 in.
Thus, the area is A = (average length)(height) = (4.5 in)(3 in) = 13.5 in^2

[tex]\frac{3}{4}[/tex] 4
[tex]\frac{5}{8}[/tex] 2

Now we can draw the line plot as attached.
Average height of the seedlings = [tex]\frac{2(\frac{1}{2})+4(\frac{3}{4})+2(\frac{5}{8})+2(\frac{7}{8})}{2+4+2+2}[/tex]
= [tex]\frac{1+3+1.25+1.75}{10}[/tex]

Answer:
$2450
Step-by-step explanation:
Understand the function gives you the profit when x is the number of meals. You are asked for the profit for 50 meals. You solve it by evaluating the function with x=50.
P = -2(50²) +152(50) -150
P = -5000 +7600 -150
P = 2450
Amelia will make $2450 in profit when she caters 50 meals.

Josie wants to hang a “Happy Birthday” banner across the diagonal of a rectangular opening that has a width of 9 feet and a height of 12 feet.
How many inches long should the banner be?
Length of banner is 15 feet
Given that;
Width of rectangle = 9 feet
Length of rectangle = 12 feet
Find:
Length of banner
Computation:
Length of banner = Length of diagonal
[tex]Length\ of\ diagonal = \sqrt{Length^2 + Width^2}\\\\ Length\ of\ diagonal = \sqrt{12^2 + 9^2}\\\\ Length\ of\ diagonal = \sqrt{144 + 81}\\\\ Length\ of\ diagonal = \sqrt{225}\\\\ Length\ of\ diagonal = 15 \ feet[/tex]
So,
Length of banner = 15 feet

7x +5=180
7x=175
x=25.
Then put the x in the 3x+3
3(25) +3 = 78

The length of Kathy's rectangular
garden is 4 feet more than the width. If
the perimeter of her garden is 40 feet,
what is the length of Kathy's garden?
Half the perimeter is the length + the width.
Let the width = x
The length is x + 4. ( 4 feet more than the width)
Now you have x + x + 4 = 20
Combine like terms:
2x + 4 = 20
Subtract 4 from both sides:
2x = 16
Divide both sides by 2:
X = 8
The width is 8 feet
The length is 8 + 4 = 12 feet

If a number is doubled and 12 is added to it. The result is 40 what's the number
Answer:
To solve for n, working backwards can help a lot.
Step-by-step explanation:
The last step we took to result in 40 was to add 12. Therefore, working backward would acquit us to subtract 12.
40 - 12 = 28
After we have done that, we need to observe the first step that we took. This was to double n. Similar, to the last order of operations we took in the previous step, we need to perform the opposite of doubling a number. Because the number is being doubled, it is being multiplied by itself. For example, if we double 4, we would receive 8. Likewise, 4² is 8. So, what is the opposite of multiplication? Well, it's division of course!
28 ÷ 2 is 14.
Therefore, n is 14.
