Answer:
18k
Step-by-step explanation:
To solve this, you must first multiply -3 by (10+3k). This leaves you with -30-9k. Next, compare which values you need to make the two equations equal. -30=-30, but -9k does not equal 9k. So, you need to add 18k to make the equations equal.

A hovercraft travels at 40 km / h over level ground and 10 km / h over a
choppy body of water. If the hovercraft took 5.75 hours to cover 185 km, how far
has he traveled on the ground and on the water?
9514 1404 393
Answer:
170 km on the ground15 km over waterStep-by-step explanation:
Let t represent the amount of time spent over level ground. Then 5.75-t is the time spent over water. The total distance covered is ...
distance = speed · time
40(t) + 10(5.75 -t) = 185
30t + 57.5 = 185
30t = 127.5
t = 4.25
40t = 170
185 -170 = 15
The hovercraft covered 170 km on the ground and 15 km on the water.

Hailey wants to brighten up her front yard by adding some flowers. She decides on zinnias and marigolds. She wants more than 3 trays of marigolds, which cost $12.00 each, and at least 5 trays of zinnias, which cost $10.00 each. How many of each can she buy if she has a budget of $150.00? Let the number of zinnias = and the number of marigolds = .
Answer:
5 Marigolds and 9 Zinnias
Step-by-step explanation:
5x12=60
9×10=90
90+60=150
So that is your answer
Hailey can buy at least 5 trays of marigolds and 9 trays of zinnias with a budget of $150.00.
Let's solve the problem step by step. Let the number of trays of zinnias that Hailey buys be represented by the variable 'Z', and the number of trays of marigolds be represented by the variable 'M'.
Each tray of marigolds costs $12.00, so the total cost of the marigolds would be 12M. Hailey wants more than 3 trays of marigolds, so M > 3.
Similarly, each tray of zinnias costs $10.00, so the total cost of the zinnias would be 10Z. Hailey wants at least 5 trays of zinnias, so Z ≥ 5.
Hailey has a budget of $150.00, so the total cost of the flowers cannot exceed $150.00. Therefore, we can write the following inequality:
12M + 10Z ≤ 150
To find the possible values of M and Z that satisfy the given conditions, we can use trial and error or a systematic approach. Let's check a few values that satisfy the given conditions:
For M = 4 and Z = 5:
12(4) + 10(5) = 48 + 50 = 98, which is less than $150.00, so this is a valid solution.
For M = 5 and Z = 9:
12(5) + 10(9) = 60 + 90 = 150, which is equal to $150.00, so this is also a valid solution.
Other possible combinations could be M = 6 and Z = 5, M = 6 and Z = 6, and so on.

!!20 POINTS!! Claire filled up her car with gas before embarking on a road trip across the country. Let G represent the number of gallons of gas remaining in her gas tank after driving for t hours. A graph of G is shown below. Write an equation for G then state the slope of the graph and determine its interpretation in the context of the problem.
Answer:
[tex]G=-\frac{5}{4}t+15[/tex]
Slope = [tex]-\frac{5}{4}[/tex]
Step-by-step explanation:
Let the equation representing the number of gallons left in the gas tank is,
G = mt + b
Where m = slope of the line
b = y-intercept of the line
Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the line passing through (8, 5) and (4, 10),
m = [tex]\frac{10-5}{4-8}[/tex]
m = -[tex]\frac{5}{4}[/tex]
Equation of line will be,
G = [tex]-\frac{5}{4}t+b[/tex]
Since, point (8, 5) lies on this line,
5 = [tex]-\frac{5}{4}(8)+b[/tex]
5 = -10 + b
b = 15
Therefore equation of the function will be,
G = [tex]-\frac{5}{4}t+15[/tex]
Here slope of the function represents the [tex]\frac{5}{4}[/tex] gallons of gas is consumed to drive the car for one hour.
In a field of wildflowers, the number of flowers is decaying exponentially. One year there are 1,200 flowers, and the next year there are 900 flowers.
The percent of decrease is _____ and the decay factor is _____.
33% .75
20% .67
30% 1.25
25% .70
Answer:
25% .70
Step-by-step explanation:
If we subtract 900 from 1,200, we get 300. If we take 300 and multiply it by 4, we get 1,200. meaning that 300 is going to be 25% so since 300 is taken away, the decrease is 25%. Im not so sure about the decay factor but since 25% .70 is our only answer with a 25% decrease, our answer is going to be D.

Answer:
x=8
Step-by-step explanation:
First we know that 14x +1 and 11x-21 are supplementary angles because they add to 180 degrees. That is the given. Now we need to make an equation.
(14x+1) + (11x-21) = 180
Simplify the equation
25x -20 =180
Addition property of equality
25x =200
Division property of equality
x =8
A man invests an amount, A, into a bank
account. After 15 years (in the 16th year) he deposits another $10 000.
After 50 years he has (in the 51st year) $251 894.21 in the account. If the amount of money in the account doubles
every 15 years, how much was his initial deposit A? [4]
Answer:
The initial amount, A is approximately $19,991.1.
Step-by-step explanation:
The initial amount the man invests in the bank = A
The amount the man deposits after 15 years = $10,000
The amount in the account after 50 years = $251,894.21
The amount of money after every 15 years = 2 × Initial amount
Therefore, we have;
The amount in the account 15 years after when the man deposits another $10,000 = 2 × A
Therefore the initial amount at the 15th year = 2·A + 10000
The
We have;
2·A = A·(1 + r)¹⁵
(1 + r)¹⁵ = 2
1 + r = 2^(1/15)
r = 1 - 2^(1/15) = 0.04729412282
Therefore, we have;
On the 50th year, 50 - 15 = 35 year
$251,894.21 = (2·A + 10000)·(1 + 0.04729412282)³⁵
A = ($251,894.51/((1 + 0.04729412282)³⁵) - 10000)/2 ≈ $19991.1
The initial amount, A ≈ $19991.1.

m=3
The slope can be found by finding the rise and run of the line
The slope of the line that passes through the points (5, 6) and (5, 9) is infinite
Reason:
The given points on the line are; (5, 6) and (5, 9)
The slope of the line that passes through the given points = Required
Solution:
The x-values of the given points are equal, therefore, the equation of the line that passes through the given points is x = 5
The slope, m, of the line is infinite because;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]Therefore, for the given points, (5, 6) and (5, 9), we have;
[tex]Slope, \, m =\dfrac{9-6}{5-5} = \dfrac{9}{0} = \infty[/tex]Therefore, the slope of the line that passes through the points (5, 6) and (5, 9) is infinite

The base of a triangle is 4 meters shorter than the height. What are the height and length of the triangle if its area is 48 square meters? *
Answer: H=12 and B=8
Looking at the problem, you are given the area, a , and told the h is 4 meters longer than b; in other words, h=b+4.
Since a=1/2bh, you can replace a with 48. Also, since h is b+4, you can replace that as well. You'd end up with this equation:
48=1/2b(b+4)
1. Seeing that 48 is 1/2 of b, you know that you have twice the value of 48, or 96. So, you can put that 96=b(b+4).
2. Now, thinking through factors of 96- 1 x 96, 2 x 48, 3 x 32, 4 x 24, 6 x 16, or 8 x 12, the only pair in which h is b+4 is 12 x 8.
