Answer:
[tex]\texttt{Submarine's depth relative to sea level after the first minute = }-\frac{4}{15} miles[/tex]
Step-by-step explanation:
Starting at sea level, a submarine descended at a constant rate to a depth of −4/5 mile relative to sea level in 3 minutes.
Total time = 3 minutes
[tex][tex]\texttt{Total depth descended in 3 minutes = }-\frac{4}{5}miles[/tex][/tex]
We need to find what was the submarine's depth relative to sea level after the first minute,
[tex]\texttt{Depth descended in per minute = }-\frac{\frac{4}{5}}{3}=-\frac{4}{15}miles[/tex]
[tex]\texttt{Submarine's depth relative to sea level after the first minute = }-\frac{4}{15}\times 1=-\frac{4}{15} miles\\\\\texttt{Submarine's depth relative to sea level after the first minute = }-\frac{4}{15} miles[/tex]

Use the distributive property to express 16+48
Final answer:
The sum of 16 and 48 can be expressed using the distributive property by factoring out the common factor of 16, yielding 16 + 48 = 16(1 + 3).
Explanation:
The question involves using the distributive property, a concept in mathematics, to express the sum of two numbers, specifically the numbers 16 and 48. To apply the distributive property, we look for a common factor that can be factored out. In this case, the common factor of both 16 and 48 is 16. Therefore, we can express the sum as:
16 + 48 = 16(1 + 3)Here, we've factored out the number 16 that is common to both terms in the sum. The distributive property allows us to then multiply 16 by each term inside the parentheses to get back the original expression.
This is an example of how the distributive property can simplify expressions and aid in mental calculations, such as understanding that 48 can be divided evenly by 16, resulting in 3.
What is 57.15% rounded to the nearest whole percent?
The number we would get when we round 57.15% to the nearest whole number is: A. 57%.
What is Nearest Whole Percent?Nearest whole percent means the number has no fractional part of decimal.
Given the number, 57.15%, to round it to the nearest whole number, digits 1 and 5 would be removed since the last number closer to the whole number is less than 5.

Of video game that originally cost $25.99 is on sale for 50% off if you have $14 would you have enough money to buy the video game explain (estimate)
Final answer:
After calculating 50% of $25.99, which is approximately $13, we find that the estimated sale price of the video game is $13. Therefore, if the student has $14, they will have enough money to buy the discounted video game.
Explanation:
The student is asking whether $14 would be enough to purchase a video game that is on a 50% off sale from its original price of $25.99. To find the sale price, we can take 50% of the original price and subtract it from the original price itself.
First, calculate 50% of $25.99: (0.50) imes $25.99 = $12.995. Since we are estimating, round the 50% value to $13. Now, subtract that from the original price to get the sale price: $25.99 - $13 = $12.99 (rounded to $13 for easier calculation).
In this estimate, the sale price is $13, which means that if the student has $14, they would have enough money to buy the video game on sale because $14 is greater than $13. Therefore, they will have $1 left after the purchase.

A cone has a diameter of 18 units and height of 8 units. What is its volume?
Answer:
289
Step-by-step explanation:
btw i need the point pls dont use this
Final answer:
The volume of a cone with a diameter of 18 units and height of 8 units is approximately 678.58 cubic units, calculated using the formula V = 1/3πr²h.
Explanation:
The student is asking about the volume of a cone with a given diameter and height. To calculate the volume (V) of a cone, you can use the formula:
V = ⅓πr²h
where π (pi) is approximately 3.14159, r is the radius of the base of the cone, and h is the height of the cone.
The diameter is given as 18 units, so the radius (r) is half of the diameter, which is 9 units. The height (h) is given as 8 units. By substituting these values into the formula, the calculation for the volume is:
V = ⅓π(9 units)²(8 units)
V = ⅓π(81 units²)(8 units)
V = ⅓π(648 units³)
V = 216π units³
When we calculate this using the approximate value of π, the volume is:
V = 216 × 3.14159 units³
V = 678.58464 units³
The volume of the cone is approximately 678.58 cubic units.

There are 16 sixth graders and 20 seventh graders in the robotics club. For the first project the club sponsor wants to organize the club members into equal size groups. Each group will have only sixth graders or only seventh graders how may students will be in each group if each group has the greatest possible numbers of club members?
Answer:
There will be 4 students in each group and there will be 9 groups.
Step-by-step explanation:
There are 16 sixth graders and 20 seventh graders in the robotics club.
As we have to find the number of students that will be in each group if each group has the greatest possible numbers of club members, so we will find the HCF or highest common factor of 16 and 20.
16 = 2 x 2 x 2 x 2
20 = 2 x 2 x 5
HCF = 2 x 2 = 4
So, 16 sixth graders will be divided in [tex]\frac{16}{4}=4[/tex] groups
20 seventh graders will be in [tex]\frac{20}{4}=5[/tex] groups
total groups = [tex]4+5=9[/tex]
Hence, total there will be 9 groups with 4 students in each group.

1. Write the ratio in the simplest form. 16:24 (1 point) 1:2 4:3 3:4 2:3
Any ratio can be simplified into its simplest form by dividing the numerator and denominator by the common factor.
The given ratio is 16:24. To bring the ratio in its simplest form we will look for the factors of 16 and 24 and look for the greatest number that divides both 16 and 24.
The greatest number that divides both 16 and 24 is 8.
16÷8=2
24÷8=3.
The ratio 16:24 in its simplest form is 2:3
The solution for the ratio in the simplest form is, 2 : 3
Given that,
16:24 is the specified ratio.
Now, By finding the largest integer that divides both 16 and 24 and the factors of 16 and 24, we may reduce the ratio to its most basic form.
Hence, 8 splits both 16 and 24 to the maximum possible extent.
So, we get;
16 / 8 = 2
24 / 8 = 3
Thus, the simplest form of the fraction is,
⇒ 16 : 24
⇒ 16 / 24
⇒ 2 / 3
It can be written as,
⇒ 2 : 3
So, the simplest form is,
⇒ 2 : 3

The function f(x) is graphed on the coordinate plane.
What is f(−2) ?
Enter your answer in the box.
f(−2)=
Answer:
The value of f(-2) is, -2
Step-by-step explanation:
The graph which is shown on the coordinate plane passes through the two points i.e, (2,0) and (0, -1).
First find the equation for this line:
Using Point-Slope form for the equation of line: [tex]y-y_{1}=m(x-x_{1})[/tex] ..[1]
where m is the slope given by ;
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
First find the slope:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{-1-0}{0-2}[/tex]
⇒ [tex]m=\frac{-1}{-2} =\frac{1}{2}[/tex]
Now, substitute the value of m=[tex]\frac{1}{2}[/tex] , [tex]x_{1}[/tex]= 2and [tex]y_{1}[/tex]=0 in equation [1];
[tex]y-0=(\frac{1}{2})(x-2)[/tex] or
[tex]y=\frac{1}{2}\cdot (x-2)[/tex]
In this graph x represents the input of the process and Y the output of the process and f the function of the variable x i.e, y=f(x)
∴ [tex]y=f(x)=\frac{1}{2}(x-2)[/tex] ....[2]
now, we put the value of x=-2 inequation [2] to solve for f(-2).
[tex]f(-2)=\frac{1}{2}(-2-2) =\frac{1}{2} \cdot (-4)[/tex]
Simplify we get;
[tex]f(-2)=-2[/tex]
4. FH bisects ∠GFI, m∠EFG = 4y + 8 and m∠HFI = 2y + 6. Find m∠EFH.
please help me solve this
Answer:
m∠EFH=134
Step-by-step explanation:
FH bisects ∠GFI
So m<GFH=m<HFI
m∠EFG = 4y + 8 and m∠HFI = 2y + 6
m<GFH=2y+6
[tex]m<EFG+m<GF+m<HFI= 180[/tex] because its a linear pair
[tex]4y+8+2y+6+2y+6=180[/tex]
combine like terms and solve for y
[tex]8y+20=180[/tex]
Subtract 20 from both sides
[tex]8y=160[/tex]
Divide both sides by 8
y=20
m∠EFH=m<EFG+m<GFH
m∠EFH=[tex]4y+8+2y+6=6y+14=6(20)+14=134[/tex]
