Dana is creating a video. Her computer shows that the video is 265.038 seconds long. She writes the length of the video in expanded form. Which expression represents the value of one of the digits in the length of Dana's video?
Options aren't supplied. However, a list of possible answers have been worked out.
Answer:
Kindly check explanation
Step-by-step explanation:
In expanded format :
256.038 can be broken down as :
2 represents 200 ; 2 hundred = 2 * 100
5 represents 5 tens = 50 = 5 * 10
6 represents 6 unit = 6 * 1
0 represents 0 tenths
3 represents 3 hundredths = 3 * 1/100
8 represents 8 thousandths = 8 * 1/1000
The options aren't given, but the answer would be among the values listed above

has a slope of 3.
Answer:
y = 3x + 8
Step-by-step explanation:
y = 3x + b
-1 = 3(-3) + b
-1 = -9 + b
8 = b
Un cubo tiene una superficie de 54 cuadrados. Metros. ¿Cuál es el volumen del cubo en ¿metros cubicos?
Answer:
27 cubic meters
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Area of cube = 54 square meters
Let, Side = a
Then, Area of cube = 6[tex]a^{2}[/tex]
54 = 6 [tex]a^{2}[/tex]
[tex]a^{2}[/tex] = 9
a = 3
So, we can calculate the volume of cube by using following formula
Volume of cube = [tex]a^{3}[/tex]
By putting the value in the formula, we get
Volume of the cube = [tex]3^{3}[/tex]
= 27 cubic meters
In RST, the measure of ZT=90°, the measure of ZR=6°, and RS = 3.6 feet. Find the
length of ST to the nearest tenth of a foot.
Question: In ΔRST, the measure of ∠T=90°, the measure of ∠R=6°, and RS = 3.6 feet. Find the length of ST to the nearest tenth of a foot.
Answer:
0.4 Feet
Step-by-step explanation:
From the question,
Applying
SinФ = Opposite/Hypotenuse
SinФ = ST/RS............... Equation 1
From the diagram attached below,
Given: Ф = 6°, ST = y feet, RS = 3.6 feet
Substitute these value into equation 1
Sin6° = y/3.6
make y the subject of the equation
y = 3.6(sin6°)
y = 3.6(0.1045)
y = 0.3762
y = 0.4 feet
Therefore Length ST = 0.4 feet

For part (a), you don't need to type in the "y=" portion as that is already done for you. For any answer choice involving a percentage, type in the number only. This is because the percent sign is already taken care of.
====================================================
Explanation:
Part (a)
Note how each time x goes up by 1, y drops by 0.2
We can see that
slope = rise/run
slope = (change in y)/(change in x)
slope = (-0.2)/(1)
slope = -0.2
This tells us that the battery life goes down by 20 percentage points for each hour. Note: This is not the same as saying it drops by 20% each time, as this is a subtle difference; however, I can see what your teacher is trying to say for part (b).
The y intercept is b = 1 since this is the location where the graph crosses the y axis.
The slope m = -0.2 and y intercept b = 1 leads y = mx+b to turn into y = -0.2x+1 which is the final answer for part (a).
As a way to check, plug in x = 0 and you should get y = 1. Plug in x = 1 and you should get y = 0.8, and so on. The (x,y) values should match what the graph shows.
----------------------------
Part (b)
As mentioned previously, the slope tells us how much the battery is changing. It's the rate of change. Specifically in this case, the battery is losing 20 percentage points for each hour. Your teacher should have used this careful phrasing, rather than say "the battery life goes down by 20% for each hour" but I can see what they're going for. So 20 is the answer for the first box of part (b)
The x intercept is where the graph crosses the x axis, which is x = 5 in this case. The x intercept always happens when y = 0. When y = 0, the battery is completely dead at 0%. Therefore, we can get 5 hours of battery life. The value 5 goes in the second box of part (b).
On the other end of the spectrum, the battery is 100% full when x = 0, which is at the start of everything. This is due to the y intercept b = 1.0 which represents 100%. In other words, the person starts off with a 100% charge, and they use their laptop for 5 hours, at which point the battery is at 0%. The value 100 goes in the third box for part (b)
----------------------------
Part (c)
We are asked to find the value of x when y = 0.75
y = -0.2x+1
0.75 = -0.2x+1
0.75-1 = -0.2x
-0.25 = -0.2x
-0.2x = -0.25
x = -0.25/(-0.2)
x = 1.25
After 1.25 hours the battery is at 75%

There are 8 red, 5 yellow, and 7 green cubes in a box. What is the probability of drawing a yellow cube and then a green cube, if the first cube is not replaced before the second cube is drawn? *
A)1/2
B)1/4
C)7/80
D)7/76
Will give extra points and brainlist
Answer:
D) 7/76
Step-by-step explanation:
There are 20 cubes in total
So our first drawing of a yellow cube is 5/20.
Our second drawing of a green cube is 7/19.
We then multiply these fractions together to get our probability.
(5/20) * (7/19) = 0.09210526315 or 7/76ths
Our answer is D

A pole casts a 6-foot shadow. If the distance from the top of the pole to the tip of the shadow is
10 feet, how many feet high is the pole?
a) 4
b) 8
c) 12
d) 16
e) 20
Answer:
8feet high
Step-by-step explanation:
To get the height of the pole, we will use the pythagoras theorem. Let H be the height
H² = 10² -6²
H² = 100 - 36
H² = 64
H = √64
H = 8feet
Hence the pole is 8feet high
16) Jenna is responsible for changing the broken light bulb in a streetlamp. The streetlamp is 14 feet high. Jenna places the base of her ladder 3 feet from the base of the streetlamp. Jenna can extend the ladder from 10 feet to 14 feet. How long must her ladder be to reach the top of the streetlamp? Will her ladder work?
Use the Pythagorean theorem:
Height is 14, base is 3, so we can calculate the length required.
Length = sqrt(14^2 + 3^2)
Length = sqrt( 196 + 9)
Length = sqrt(205)
Length = 14.32 feet.
The ladder needs to be 14.32 feet. The longest her ladder can be is 14 feet so her ladder won’t work.

A card is drawn from a standard deck of cards. What is the probability
that a spade is drawn, then replaced, and a red card is drawn second?
A card is drawn from a standard deck of cards. What is the probability that a spade is drawn, NOT replaced, and another spade is drawn?
Answer:
With replacement
[tex]probability \ of \ spade = \frac{13}{52} = \frac{1}{4} \\\\ probability \ of red\ card = \frac{26}{52} =\frac{1}{2}[/tex]
[tex]probability \ of \ spade \ then \ red\ card\ without\ replacement =[/tex][tex]\frac{1}{4} \times \frac{1}{2} = \frac{1}{8}[/tex]
Without replacement
[tex]probability \ of\ spade = \frac{13}{52} = \frac{1}{4} \\\\probability \ of \ spade\ again =\frac{12}{51} = \frac{4}{17}[/tex]

A person hikes 4 miles in 2.5 hours. Find the unit rate in miles per hour.
mi/h
h/mi
How is each unit rate useful in a real-life situation
Answer:
1.6 mi / hr
0.625 hr / mi
Step-by-step explanation:
4/2.5 = x / 1
2.5/2.5 = 1
So, 4 / 2.5 = 1.6
1.6 mi / hr
4= m
2.5 = hr
4 / 4 = 1
2.5 / 4 = 0.625
0.625 hours / mile

Four of the interior angles of a hexagon measure 92°, 100°, 94°, and 140°. The remaining two angles each measure (x−32)°. What is the value of x? Justify your response.
A. The sum of all interior angle measure is 540°
, so each angle measuring (x−32)° has a measure of 123°
. Thus, (x−32)°=123°, and so x=155.
B. The sum of all interior angle measure is 720°
, so each angle measuring (x−32)° has a measure of 294°. Thus, (x−32)°=294°, and so x=326.
C. The sum of all interior angle measure is 720°
, so each angle measuring (x−32)° has a measure of 147°
. Thus, (x−32)°=147°, and so x=179.
D. The sum of all interior angle measure is 540°
, so each angle measuring (x−32)° has a measure of 246°. Thus, (x−32)°=246°, and so x=275.
Answer:
The answer is x=294 (B)
Step-by-step explanation:
Remember, all interior angles of a hexagon add to 720.
So add all the given numbers first.
92+100+94+140+x= 720
426+x=720
-426 from both sides
x= 294
