During a scuba dive, Lainey descended to a point 23 feet below the ocean surface. She continued her
descent at a rate of 23 feet per minute. Enter an inequality you could solve to find the number of minutes
she can continue to descend if she does not want to reach a point more than 97 feet below the ocean
surface. Use t to represent the variable for the minutes Lainey can continue to descend.
The inequality is
t (select)
t (23) ≤ 97 - 23
The minus 23 at the back represents the feet she already descended before what the question wants us to calculate
≤ is used instead of < because it states more than, not "equal or more than" (meaning 97 sharp is fine)

Write an explicit formula for a-n, then term of the sequence 36, 39, 42,....
Answer:
a^n = 36 + (n-1) * 3
Step-by-step explanation:
Explicit formula for arithmetic sequences: a^n = a^1 + (n-1) * d
In this case, a^1 = 36 and common difference/d = 3
So...
a^n = 36 + (n-1) * 3 is the explicit formula for this sequence.

In the figure above, are <3 and <7 alternate interior angles,
same-side interior angles, corresponding angles, or alternate
exterior angles?
Answer:
Corresponding angles
Step-by-step explanation:
<3 and <7 lie on the same side of the transversal line. Each angle also is located on the outside of each parallel lines cut across by the transversal.
Therefore, <3 and <7 are corresponding angles.
8kg ham costs $12/kg. find the cost per pound.
Answer:
The cost per pound is: $5.45 per pound
Step-by-step explanation:
Given
8kg ham costs $12/kg
To determine
Find the cost per pound
As
1 kg = 2.2 pounds
Weight of 8kg in ponds = 8 × 2.2 = 17.6 ponds
Cost of ham/pound = $12/2.2 pounds
= $5.45 per pound
Thus, the cost per pound is: $5.45 per pound
A zookeeper is monitoring the supply of grain and hay that she has to feed the
animals for the week. She currently has eight pounds of hay. One pound of hay
feeds the animals for three days. The grain that she has to feed the animals is
shown in the graph below. Given the rate at which the zookeeper is giving the
animals hay and grain, on which day will she have the same amount of grain and hay remaining?
Answer: Day 6
Step-by-step explanation: Every 3 days 1 pound of hay is used every day 1 pound of grain is used. There are 10 pounds of grain and 8 pounds of hay. On the 6th day there are 6 pounds of hay left and 6 pounds of grain left.

Which expression is equivalent to Oy-3?
O 3ty-1)
O 3(3-1)
O 9(y-3)
O 9(3y-3)
Answer:
3(3y-1)
Step-by-step explanation:
To find out which expression is equivalent, expand and simplify the options listed to see which one equals 9y-3.
Let's try the second option. To simplify the expression, use the distributive property. So, multiply each term in the parentheses by 3:
[tex]3(3y-1)\\= 9y-3[/tex]
Thus, the answer would be the second option.
In 45 years will be 4 times older how old is she now
Answer and Step-by-step explanation:
The key for this has a current age and a future age. Sometimes these problems have more than one person or has a past age.
current age future age
x x+45
The future age is 4 times current age
x+45 = 4x
45 = 3x
15 = x
She is currently 15. 45 years from now she will be 60.
60 is 4 times her current age. So right now, she is 15.

if you spent 6 hours a week studying for English and 2.5 hours studying for math what is the ratio of time spent studying in math to studying for English ?
Answer: If you spend 7 hours a week studying for English, and 4.5 hours studying for math what is the ratio of time spent studying math to studying English?
Math: English
4.5: 7 Now you divide both sides by 4.5 to get 1 on one side
1: 1.555556
So the ratio of time spent studying math to english is 1 to 1.555556. Hope I helped

Mia has 4 horses and 11 apples. She gives each horse the same number of
apples, and she uses as many apples as she can. How many apples does Mia
give each horse? How many apples are left?
» Complete the equation.
11 : 4 =
R
Answer:
She gives 2 apples to each horse, and there will be 3 apples left.
Step-by-step explanation:
We know that Mia has 4 horses and 11 apples
She gives each horse the same number of apples, such that she uses the maximum number of apples that she can.
If she has 4 horses and she gives the same amount to each horse (let's say that this amount is N apples to each horse)
Then she uses a total of 4*N apples.
Then if N = 1, she needs 4*1 = 4 apples.
if N = 2, she needs 4*2 = 8 apples.
if N = 3, she needs 4*3 = 12 apples.
But she has only 11 apples, so she can not give 3 apples to each horse.
Then the maximum number of apples that she can give to each horse is N = 2, 2 apples to each horse.
Now, we know that she has 11 apples in total, and she gives 2 to each of the 4 horses, then she gives:
4*2 = 8 apples.
The number of apples that are left are:
11 - 8 = 3
There are 3 apples left.
Simplify -2 (x+8) +1 (3x+16)
Answer:
Ans : =x
brainliest plsssssss
Step-by-step explanation:
Let's simplify step-by-step.
−2(x+8)+1(3x+16)
Distribute:
=(−2)(x)+(−2)(8)+(1)(3x)+(1)(16)
=−2x+−16+3x+16
Combine Like Terms:
=−2x+−16+3x+16
=(−2x+3x)+(−16+16)
=x
CALCULUS: For an object whose velocity in ft/sec is given by v(t) = sin(t), what is its distance, in feet, travelled on the interval t = 1 to t = 5?
A. 0.45
B. 2.82
C. 0.03
The linked answer is wrong because that integral gives you the net displacement of the object, not the total distance.
To get the distance, you have to integrate the speed (as opposed to velocity), which involves integrating the absolute value of the velocity function.
[tex]\mathrm{distance} = \displaystyle\int_1^5 |\sin(t)| \,\mathrm dt[/tex]
By definition of absolute value,
[tex]|\sin(t)|=\begin{cases}\sin(t)&\text{for }\sin(t)\ge0\\-\sin(t)&\text{for }\sin(t)<0\end{cases}[/tex]
Over this particular integration interval,
• sin(t ) ≥ 0 for 1 ≤ t < π, and
• sin(t ) < 0 for π < t ≤ 5
so you end up splitting the integral at t = π as
[tex]\mathrm{distance} = \displaystyle\int_1^\pi \sin(t)\,\mathrm dt + \int_\pi^5 (-\sin(t))\,\mathrm dt[/tex]
Now compute the distance:
[tex]\mathrm{distance} = -\cos(t)\bigg|_1^\pi + \cos(t)\bigg|_\pi^5[/tex]
[tex]\mathrm{distance} = -(\cos(\pi) - \cos(1)) + (\cos(5) - \cos(\pi))[/tex]
[tex]\mathrm{distance} = -2\cos(\pi) + \cos(1) + \cos(5) \approx 2.82[/tex]
making B the correct answer.
