youre subtracting a negative, which makes it positive. anytime you subtract a negative, its just addition :)
Answer:
2
Step-by-step explanation:
Ok, so it's you are subtracting a negative three from negative one. Since you are subtracting a negative it basically cancels it the negative out and makes it a positive number. So -3 would be 3. It would look like -1 +3, and that's how the answer is 2. Hopes this helps! :D

Recall the hurricane relief fund context from the previous investigation. Bob set up a hurricane relief donation fund and started it off by donating $ 35 . Instead of tripling in value each day, suppose it doubled in value each day
This question is Incomplete
Complete Question
Recall the hurricane relief fund context from the previous investigation. Bob set up a hurricane relief donation fund and started it off by donating $ 35 . Instead of tripling in value each day, suppose it doubled in value each day
Complete the following table showing the account values at the end of each day.
Number of days since the initial investment, n Amount (in dollars) in the relief account, A
0 1 2 3 4
Answer:
Number of days(n) = Amount (in dollars) in the relief account(A)
0 = $35
1 = $70
2 = $140
3 = $280
4 = $560
Step-by-step explanation:
The formula for doubling time
P(t) = Po(2)^t/k
Where P = Amount after time t
Po = Initial Amount
t = number of days
k = Frequency at which it doubles
For 0 days
t = 0, k = 1, P(o) = $35
P(t) = Po(2)^t/k
P(0) = $35(2)^0/1
= $35(2)⁰
= $35 × 1
= $35
For 1 day
t = 1, k = 1 , P(0) = $35
P(t) = Po(2)^t/k
P(0) = $35(2)^1/1
= $35(2)¹
= $35 × 2
= $70
For 2 days
P(t) = Po(2)^t/k
t = 2, k = 1, P(0) = $35
P(0) = $35(2)^2/1
= $35(2)²
= $35 × 4
= $140
For 3 days
P(t) = Po(2)^t/k
t = 3, k = 1
P(0) = $35(2)^3/1
= $35(2)³
= $35 × 8
= $280
For 4 days
P(t) = Po(2)^t/k
t = 3, k = 1, P(0) = $35
P(0) = $35(2)^5/1
= $35(2)⁴
= $35 × 16
= $560

What is the solution to this inequality?
17 + x2 33
O A. x216
B. x2 50
C. xs 50
O D. xs16
x≤ 16 is the solution of the given 17 + x≤ 33 inequality, Option D is correct.
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is 17 + x≤ 33
We have to find the solution of the inequality seventeen plus x less than or equal to thirty three.
Now let us solve for x
Subtract seventeen from both sides to isolate the x variable.
17 + x - 17 ≤ 33 -17
In left hand side the seventeen will be cancelled and left with only variable x
x≤ 33 -17
When seventeen is subtracted from thirty three we get sixteen
x≤ 16 is the solution
Hence, x≤ 16 is the solution of the given 17 + x≤ 33 inequality, Option D is correct.

Find the length of the radius. Write your answer as
a simplified radical.
Step-by-step explanation:
Hey there!
Here;
A chord of a circle AB is given with measure of 24 cm.
Let O be the centre of a circle and OP is perpendicular to AB.
Now, draw an imaginary line from O to B. [To make a radius].
Now;
[tex]bp = \frac{1}{2} \times ab[/tex]
[tex]bp = \frac{1}{2 } \times 24[/tex]
Therefore BP = 12.
Again;
You can clearly see that POB is a Right angled triangle.
Now,
Using Pythagoras relation we get;
[tex] {ob} = \sqrt{ {po}^{2} + {bp}^{2} } [/tex]
[tex]ob = \sqrt{ {8}^{2} + {12}^{2} } [/tex]
[tex]ob = \sqrt{64 + 144} [/tex]
[tex]ob = \sqrt{208} [/tex]
Therefore OB = 14.42.
As OB is a radius, the value of radius is 14.42.

Darrel has 36 daisies and 54 roses. He wants to put an equal number of daisies and roses into vases. What is the GREATEST number of daisies and roses Darrel
can put in each vase?
Answer:
18 number of daisies and 18 number of roses
Step-by-step explanation:
We are told Darrel has 36 daisies and 54 roses.
And that He wants to put an equal number of daisies and roses into vases.
To get the equal number, it means we have to find the greatest common factor of 36 and 54.
Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36
Factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54
From the factors of both 36 and 54, the greatest common factor to both of them is 18.
Thus, the GREATEST number of daisies and roses Darrel can put in each vase is 18 each
Answer:
18

What are the values of x and y?
Answer:
For instance, the equation y = x expresses a relationship where every x value has the exact same y value. The equation y = 2x expresses a relationship in which every y value is double the x value, and y = x + 1 expresses a relationship in which every y value is 1 greater than the x value.

$80,000, and if it is installed, no losses from this type of incident will be incurred. However, if the generator is not installed, there is a 12% chance that a power outage will occur during a year. If there is an outage, there is a .07 probability that the resulting losses will be very large, or approximately $7 million in net aggregated loss. Alternatively, it is estimated that there is a .93 probability of only slight losses of around $1 million. Using decision tree analysis, determine whether the SPEA should have install the new power generator. What considerations may change your decision?
Answer:
SPEA should have install the new power generator.
Step-by-step explanation:
The information provided is as follows:
The cost of the emergency generator is $80,000, and if it is installed (I), no losses from this type of incident will be incurred. If the generator is not installed (I'), there is a 12% chance that a power outage (P) will occur during a year. If there is a power outage, there is a 0.07 probability that the resulting losses will be very large (HL), or approximately $7 million in net aggregated loss. Alternatively, it is estimated that there is a 0.93 probability of only slight losses (SL) of around $1 million.Consider the decision tree attached below.
The loss that will be incurred after the generator is installed is, $80,000.
Compute the loss that will be incurred if the generator is not installed as follows:
[tex]E(\text{Loss})=P(HL|P)P(P)\times \$7000000+P(SL|P)P(P)\times \$1000000[/tex]
[tex]=(0.07\times 0.12\times \$7000000)+(0.93\times 0.12\times \$1000000)\\=58800+111600\\=170400[/tex]
The loss that will be incurred if the generator is not installed is $170,400.
The loss from not installing the generator is more than from installing it.
Thus, SPEA should have install the new power generator.

Solve for the value of X.
60°
8x - 4
Answer:
x = 8
Step-by-step explanation:
Asuming the equation is 8x-4=60°,
Simplifying
8x + -4 = 60
Reorder the terms:
-4 + 8x = 60
Solving
-4 + 8x = 60
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 8x = 60 + 4
Combine like terms: -4 + 4 = 0
0 + 8x = 60 + 4
8x = 60 + 4
Combine like terms: 60 + 4 = 64
8x = 64
Divide each side by '8'.
x = 8
Simplifying
x = 8
