Answer:
NO
Step-by-step explanation:
Let h(t) represent the distance the pack is located above the ground at time t. Then h(t) = 20 ft - 16t^2 ft. Notice how h = 20 ft (the initial height) and that it decreases as t increases.
How long does it take for the pack tohit the ground? Set h(t) = 0 and solve for t:
0 ft = 20 ft - 16t^2 ft yields 16t^2 ft = 20, or t^2 ft = 20/16, which is greater than 1. So the question "Will the backpack hit the ground in 1 second" is answered by NO.

find the side lengths. help please, asap. thank you!
Answer:
Step-by-step explanation:
A) WX=YX
angle w =angle Y=70
X=180-2x70= 40
B) all sides are equal. Angle V=T=U=180/3=60
(a) the given triangle is a isosceles triangle. The two base (non-congruent side) angles (in this case, ∠XYW & ∠XWY) will have the same measurements.
It is given that m∠XYW = 70°, therefore, m∠XWY is also 70°.
Subtract 180 from the two 70° to get m∠X:
180 - (70 + 70) = 180 - 140 = 40°
m∠X = 40° is your answer.
~
The given triangle is a equilateral triangle (All sides are congruent). If all sides are congruent, it is a equilateral triangle, and if it is a equilateral triangle, then all measurements of the inside angles are the same, 60°
m∠V = 60°

Answer:
Area of sector of a circle = 28.26 meter²
Step-by-step explanation:
Given:
Side of cube = 12 meter
One white section = sector of a circle
Find:
Area of one white section
Computation:
Radius of circle = Side of cube / 2
Radius of circle = 12 / 2
Radius of circle = 6 meter
One white section = sector of a circle
Area of sector of a circle = [θ/360][π][r]²
Area of sector of a circle = [90/360][22/7][6]²
Area of sector of a circle = [0.25][3.14][36]
Area of sector of a circle = 28.26 meter²

Answer:
w = 325cm
Step-by-step explanation:
=> here's your solution
=> formula is v = t*w*h
=> v = 5915cm^3
=> t = 91cm
=> we need to find w = ?
=> V = T*W*H
=> w = 5915/(91*5)
=> w = 325cm

Answer:
3/2
Step-by-step explanation:
Truthfully, you only need two points for a linear equation, so I will only use two.
(-5, 0)
(-3, 3)
I will use the skeleton method to find the slope
((0) - (3))/((-5) - (-3)) -> -3/-2
The slope is 3/2

In a random sample of 5 residents of the state of Maine, the mean waste recycled per person per day was 2.6 pounds with a standard deviation of 0.69 pounds. Determine the 98% confidence interval for the mean waste recycled per person per day for the population of Maine. Assume the population is approximately normal. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answer:
(1.307 ; 3.893)
Step-by-step explanation:
Given that:
Mean, xbar = 2.6
Standard deviation, s = 0.69
Sample size, n = 5
Confidence interval : xbar ± margin of error
Margin of Error = Tcritical * s/sqrt(n)
Degree of freedom (df) = n - 1 = 5 - 1 = 4
Hence Tcritical = 3.747
Margin of Error = 3.747 * 0.69/sqrt(4)
Margin of Error = 1.293
Lower boundary = (2.6 - 1.293) = 1.307
Upper boundary = (2.6 + 1.293) = 3.893

Given that sec(θ)=5/3 and θ is in Quadrant I, what is tan(θ)? Write your answer in exact form. Do not round.
9514 1404 393
Answer:
tan(θ) = 4/3
Step-by-step explanation:
The relationship between secant and tangent is ...
1 +tan² = sec²
The the tangent of the angle is ...
tan(θ) = √(sec²(θ) -1)
tan(θ) = √((5/3)² -1) = √(16/9)
tan(θ) = 4/3
How can you write the fraction 4/10 as an equivalent fraction over 100
Answer:
40/100
Step-by-step explanation:
4/10 can be made into an equivalent fraction by multiplying each number by 10. This is because we need to change the denominator into 100 and 10x10=100.
10(4/10)=40/100
40/100 is the answer

225 is what percent on 75 solved in an equation
Answer:
300%
Step-by-step explanation:
[tex]\frac{225}{75} = \frac{y}{100}[/tex]
225 × 100 = 75 × y
22500 = 75y
75y ÷ 75 = 22500 ÷ 75
y = 300
300%

Answer:
B.
Step-by-step explanation:
The answer is B because 3/5 of 1/2 is less than 1/2. The equation that represents this problem is
3/5 x 1/2 = 3/10
3/10 < 1/2
Therefore, 3/5 is less than 1/2!

Answer:
80 degrees
Step-by-step explanation:
The only given angle here is angle 4, which measures 100 degrees.
1) Identify angle relationships
Angle 4 and angle 6 are interior angles, meaning they have a sum of 180 degrees.
2) Solve for angle 6
180-Angle 4=Angle 6
180-100=Angle 6
80=Angle 6
Therefore, the measure of angle 6 is 80 degrees.
I hope this helps!
Answer:
c. 80°
Step-by-step explanation:
We are given a shape with a bunch of lines, and are asked to find what measure is ∠6.
Solving this is simple, we just need to keep notice that what angle is larger than 90 degrees looks like and what under 90 degrees looks like. All angles that are above 90 look wide and huge, while all under is very tiny and skinny.
If we take a look at our hint, angle 4 has the (100 degrees). Look at how wide it is, if angle 6 is tinier than that, then the answers A. and B. are scratched out.
Now 90 degrees is a right angle, looking at angle 6 guarantees that D. is also not correct because it is not a right angle.
Leaving us with C. 80

How do I graph the line with slope of 3 and Y-intercept if -6?
Step-by-step explanation:
For drawing the graph , we Firstly need to find the equation of the line . We can find the line using Slope intercept form . Here ,
y intercept = (-6)slope = 3 .We know slope intercept form as ,
[tex]\implies y = mx + c \\\\\implies y = (3)x + (-6) \\\\\implies \boxed{\boxed{y = 3x - 6 }}[/tex]
Now we need to plot the graph of y = 3x -6. Refer to attachment for graph .

482 – 412 + 286 - 12 x 204solve
Answer:
70,176
Step-by-step explanation:
Given that
482 - 412 + 286 - 12 × 204
We need to solve the above equation
= 482 - 412 + 286 - 12 × 204
= 70 + 286 - 12 × 204
= 356 - 12 × 204
= 344 × 204
= 70,176
Hence, the answer to the given equation is 70,176

Triangle A’B’C’ is a dilation image of triangle ABC. Which is the correct description of the dilation?
A. Center C and scale factor 4
B. Center A and scale factor 4
C. Center A and scale factor 5
D. Center C and scale factor 5
Answer:
B.
Step-by-step explanation:
Center is the point that does not change and that point is A. To find the scale factor you just divide the translated length by the original, in this case, 8÷2 which gives a scale factor of 4.

Jose can eat 5/8 of a pizza in 1/4 hours. How many hours will it take him to eat the whole pizza?
Answer: 2/5 of an hour
Step-by-step explanation:
ok so 5/8 = .625 just to begin with...
and as a ratio it would be .625 = .25
8/8 (1)
So I did .25x1=.25
.25x.625= 0.4 or as a fraction 2/5
