Use the information to answer the question
A diver is swimming at an elevation of -8 feet when she starts to descend at a rate of 2 feet per second for 7 seconds.
What is the diver's elevation after she descends for 7 seconds? Enter the answer in the box.
feet
Answer:
-22 ft.
Step-by-step explanation:
So we know that the diver descends (goes deeper) at a rate of 2 feet per second.
We also know that he/she is already at an elevation of -8 feet.
The first we need to do to solve this question is to find out the number of feet the diver descends in 7 seconds:
We do this by multiplying the amount of time by the number of feet (7 x 2)
as we all know 7 x 2 = 14 feet
So the diver dove deeper by 14 feet.
Now we have to add 14 and 8 to find the divers new elevation:
14 + 8 = -22 ft.
The divers' elevation after descending for 7 seconds is -22 ft.
plz mark me brainliest if correct :)
The diver's elevation after she descends for 7 seconds will be -22 ft.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

14. A group of crafters is collecting data on the amount of yarn they use for each scarf knitted. Each person collected 12 pieces of data and will compile that data to determine a population mean. One crafter, Chris, has a sample mean of 200 meters of yarn.
Which statement must be true about this situation?
A. The population mean must be less than 200.
B. The population mean must be greater than 200.
C. The population mean is also 200.
D. There is not enough information to make a conclusion about the population mean.
Answer:
D. There is not enough information to make a conclusion about the population mean.
Step-by-step explanation:
One of the crafters Chris has a sample means of 200. This means that the average amount of yarn Chris used is 200 meters. Yet there is nothing else given about the other crafters, hence it is impossible to draw a conclusion.
How do you turn 6x-5y=8 into slope intercept form?
Answer:
Subtract 6x on both sides to get to this equation, -5y = -6x + 8. Then, divide -5 on both sides to get your slope-intercept which is y = 6/5x -8/5.
Work out the size of AED. Work out x
Answer:
a). m∠AED = 70°
b). x = 10°
Step-by-step explanation:
a). Quadrilateral ABDE is a cyclic quadrilateral.
Therefore, by the theorem of cyclic quadrilateral,
Sum of either pair of opposite angle is 180°
m(∠AED) + m(∠ABD) = 180°
m(∠AED) = 180° - 110°
m(∠AED) = 70°
Since, ∠AED ≅ ∠EAD
Therefore, m∠AED = m∠EAD = 70°
b). By triangle sum theorem in ΔABD,
m∠ABD + m∠BDA + m∠DAB = 180°
110° + 40° + m∠DAB = 180°
m∠DAB = 180° - 150°
m∠DAB = 30°
m∠BAE = m∠EAD + m∠BAD
= 70° + 30° = 100°
By angle sum theorem in ΔACE,
m∠EAC + m∠AEC + m∠ACE = 180°
100° + 70° + x° = 180°
x = 180° - 170°
x = 10°

3 + [tex]\sqrt{11\\}[/tex] is your expression. The conjugate is an important concept you need to know to solve this.
Given the expression: [tex]a + \sqrt{b\\}[/tex]
It's conjugate would be: [tex]a - \sqrt{b}[/tex]
(Basically if there is an addition sign between the 2 terms, it would become a subtractions symbol and if there is a subtraction symbol it would become an addition symbol)
1) So the conjugate of [tex]3+ \sqrt{11}[/tex] would be [tex]3 - \sqrt{11}[/tex]
2) Now we would have to multiply them
([tex]3 + \sqrt{11}[/tex])([tex]3- \sqrt{11}[/tex]) is your expression. If you use distribution property, you will get to: [tex]3^{2} + 3\sqrt{11} - 3\sqrt{11} + \sqrt{11}^{2}[/tex] The two middle terms would cancel out (they both add up to 0), so then we have [tex]3^{2} - \sqrt{11}^2[/tex] This would simplify into 9-11, which is then -2Hope you understood, and have a nice day!! :)

Answer:
x=70
Step-by-step explanation:
Due to the law of alternate interior angles, we can see that one of the angles in the triangle is equal to 35 degrees as well (please see the picture attached).
We're given that one of the exterior angles of the triangle is equal to 105. The exterior angle of a triangle will always be equal to the sum of the two opposite interior angles. Knowing this, we can write:
x+35=105
Subtract both sides by 35
x+35-35=105-35
x=70
Therefore, the value of x is 70 degrees.

write a linear equation that has a slope of 1/2 and a y-intercept at the origin. (y=1/2x) (y=0x+1/2) (y=1/2x+1/2) (y=-1/2x)
Answer:
The linear equation with given slope and y-intercept is:
Option 1: [tex]y = \frac{1}{2}x[/tex]
Step-by-step explanation:
The slope-intercept form of equation is given by:
[tex]y = mx+b[/tex]
Here
m is the slope of the line and b is the y-intercept.
Given that
Slope of line is 1/2 so m = 1/2
And y-intercept is on origin so b = 0
Putting the values we get
[tex]y = \frac{1}{2}x+0\\y = \frac{1}{2}x[/tex]
Hence,
The linear equation with given slope and y-intercept is:
Option 1: [tex]y = \frac{1}{2}x[/tex]

Subtract 1 on both sides: 3x = 9Divide 3 on both sides: x = 3Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(3) + 1 = 10Multiply: 9 + 1 = 10Add: 10 = 10Here we see that 10 does indeed equal 10.
∴ x = 3 is the solution to the equation.
