Tomas works as an underwater photographer. He starts at a position that is 17 feet below sea level. He rises 9 feet, then descends 15 feet to take a photo of a coral reef. Enter an expression to find his position relative to sea level when he took the photo and then evaluate the expression.
Answer:
(-17 + 9) - 15
Step-by-step explanation:
I think of below sa level as negative numbers, so 17 feet below sea level is -17. Then when he rises 9 feet that would be - 17 + 9. When he decends 15 feet to take another picture thats - 15. Then when you thing of pemdas addition goes first, so i just put parentases around -17 + 9 to get the expression (-17 + 9) - 15

Answer:
x=3
Step-by-step explanation:
Angle TRS would be 180-45x as the angle lies on a straight line and we know angles on a straight line add up to 180 degrees
Then I would add the three angles in the triangle and equate it to 180 degrees as angles in any triangle add up to 180 degrees
therefore:
(180-45x)+25x+(57+x)=180
180-45x+26x+57=180
237-19x= 180
237-180=19x
57=19x
57/19=x
3=x
x is correct as when we substitute it in the angles in the triangle, the interior angles for the triangle does add up to 180
Identify the range of the function shown in the graph.
A. 0 ≤ y ≤ 8
B. -6 ≤ x ≤ 6
C. y > 0
D. y is all real numbers.
Answer:
[tex]0\leq y\leq 8[/tex]
Step-by-step explanation:
because it cant go below x-axis with is y = o and nothing above 8
The function can produce any y-value between 0 and 8, including both 0 and 8 (option a).
The range of a function refers to the set of all possible output values, or y-values, that the function can produce. To identify the range of the function shown in the graph, we need to determine the highest and lowest y-values that the graph reaches.
Looking at the graph, we can see that the highest point on the graph is at y = 8, and the lowest point is at y = 0. Therefore, the range of the function is from y = 0 to y = 8.
In other words, the function can produce any y-value between 0 and 8, including both 0 and 8. We can express this range using interval notation as [0, 8].
So, the correct answer is option A: 0 ≤ y ≤ 8.

You had a lot of spare time this summer because of quarantine, so you and four family members took a 5-day white-water rafting and hiking trip. During your 5-day trip, 2 days were spent rafting. If the rafting trip covered a distance of 60 miles and you spent 8 hours rafting each day, how many miles did you raft each hour?
Answer:
3.75 miles per hour
Step-by-step explanation:
Given that:
Number of days spent rafting = 2 days total distance covered during rafting = 60 miles
Time spent rafting per day = 8 hours
Number of miles raft per hour:
Total number of raft hours over the 2 days = (8 * 2) = 16 hours
Total raft distance over the 2 days = 60 miles
Raft miles per hour :
Total raft distance / total number of raft hours
60 miles / 16 hours
= 3.75 miles per hour

Alexia ran three laps around her neighborhood. Each lap is 1 and StartFraction 3 over 8 EndFraction miles. Which is the best estimate of the number of miles that Alexia ran?
2 miles
3 and one-half miles
4 and one-half miles
6 miles
Answer:
4 and one-half miles
Step-by-step explanation:
The answer closest to the correct answer is 4 and one-half miles.
To get the answer, you multiply 3 times the length of one lap which is 1 and [tex]\frac{3}{8}[/tex] miles. To multiply the fraction, you take 3 times the top number in the fraction. So 3 x 1 [tex]\frac{3}{8}[/tex] = 3 [tex]\frac{9}{8}[/tex]. The fraction can actually be reduced to 1 and [tex]\frac{1}{8}[/tex] miles. So you're total correct answer is 4 and [tex]\frac{1}{8}[/tex] miles.
The second selection is 3 and [tex]\frac{1}{2}[/tex] which can also be written as 3 and [tex]\frac{4}{8}[/tex] to make it easier to determine which answer is correct. The second answer is therefore [tex]\frac{5}{8}[/tex] shorter than the correct answer.
The third selection is 4 and [tex]\frac{1}{2}[/tex] which can be written as 4 and [tex]\frac{4}{8}[/tex] so it is only [tex]\frac{3}{8}[/tex] longer than the correct answer. So this selection is the closest to the actual miles ran.

On Thursday a local hamburger shop sold a combined total of 444 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold
Answer:
148 hamburgers sold
296 cheeseburgers sold
Step-by-step explanation:
x = number of hamburgers sold
2x = number of cheeseburgers sold
444 = total burgers sold
hamburgers + cheeseburgers = total burgers sold
x + 2x = 444
3x = 444
3x/3 = 444/3
x = 148
Check:
148 + 2(148) = 444
148 + 296 = 444
444 = 444

Answer:

Step-by-step explanation:
Answer:
y = 1/3x + 3
Step-by-step explanation:
Slope form of a equation: y = mx + b. The slope is 1/3, so y = 1/3x + b
Solve for b by plugging the (x, y) coordinate into the equation.
y = 1/3x + b
2 = 1/3(-3) + b
2 = -3/3 + b
2 = -1 + b
b = 3
So your answer is y = 1/3x + 3

This question was not correctly written
Complete Question
Write a number in which the value of the digit 4 is 1/100 of the value of the digit 4 in 140.37. Explain how you know the number you wrote meets the criteria.
Answer:
0.4
Step-by-step explanation:
1/100 of the value of the digit 4 in 140.37
4 in that number is Tens place value.
This mean , 4 × 10 = 40
Hence, 1/100 of 40 is :
40 × 1/100
= 40/100
= 0.4
Hence, the number in which the value of the digit 4 is 1/100 of the value of the digit 4 in 140.37 is 0.4

What is the perimeter of a polygon with vertices at (-3, 1), (5, 1), (-3, 4), (5, 4)?
Answer:
The perimeter of the polygon is 22.
Step-by-step explanation:
Let [tex]A(x,y) =(-3,1)[/tex], [tex]B(x,y) = (5,1)[/tex], [tex]C(x,y) = (-3, 4)[/tex] and [tex]D(x,y) =(5,4)[/tex] the vertices of the polygon. From Geometry we know that number of side of polygons equals their number of vertices, then we notice that a quadrilateral is here. In addition, we conclude that such quadrilateral is a rectangle:
1) [tex]x_{A} = x_{C}[/tex]
2) [tex]x_{B} = x_{D}[/tex]
3) [tex]y_{A} = y_{B}[/tex]
4) [tex]y_{C} = y_{D}[/tex]
Hence, we find that [tex]AB = CD[/tex] and [tex]AC = BD[/tex].
Then we find all lengths of the rectangle by Pythagorean Theorem:
[tex]AB = \sqrt{[5-(-3)]^{2}+(1-1)^{2}}[/tex]
[tex]AB =8[/tex]
[tex]AC = \sqrt{[(-3)-(-3)]^{2}+(4-1)^{2}}[/tex]
[tex]AC = 3[/tex]
By Geometry, we conclude that [tex]CD = 8[/tex] and [tex]BD = 3[/tex].
Then, the perimeter of the rectangle ([tex]p[/tex]), dimensionless, is defined by the following formula:
[tex]p = 2\cdot (s+l)[/tex] (Eq. 1)
Where:
[tex]s[/tex] - Shortest length, dimensionless.
[tex]l[/tex] - Longest length, dimensionless.
If we know that [tex]s = 3[/tex] and [tex]l = 8[/tex], then the perimeter of the rectangle is:
[tex]p = 2\cdot (3+8)[/tex]
[tex]p = 22[/tex]
The perimeter of the polygon is 22.
A conservative estimate of the number of stars in the universe is 6x10^22. The average human can see about 3,000 stars at night with his naked eye.About how many more times more stars are there in the universe compared to the stars human can actually see?
Answer:
2 × 10^19 times
Step-by-step explanation:
Number of stars in universe = 6x10^22
Number of stars eye can see = 3000
About how many more times more stars are there in the universe compared to the stars human can actually see?
Number of stars in universe / number of stars eye can see
= 6x10^22 / 3000
= 6 × 10^22 / 3 × 10^3
= 2 × 10^(22 - 3)
= 2 × 10^19 times
Number of stars in universe is 2 × 10^19 times more than that which the eyes can see
