There are [tex]6\frac{1}{4}[/tex] groups of 1/5 in 5.
The simplified value of 5 ÷ 4/5 is also [tex]6\frac{1}{4}[/tex].
What is a number line?A number line is a one-dimensional horizontal line where we can represent any real number. The origin of the number line is represented by zero left to it are all negative real numbers and right to it are all positive real numbers.
From the bar given above the number line, each group has subgroups of 4.
Therefore, The number of groups of (1/5) in 5 is [tex]6\frac{1}{4}[/tex] groups.
We know when a fraction is in the division we can reciprocate the fraction and the division changes to multiplication,
Therefore, 5 ÷ 4/5 = 5×5/4 = 25/4 = [tex]6\frac{1}{4}[/tex]

A ship’s sonar detects a submarine 440 feet below a point on the ocean’s surface 600 ft dead ahead of the ship. To the nearest degree, find the angle x. hurryy!!!
Answers
The angle x to the nearest degree is 40°
Given,
The depth of submarine that a ship's sonar detects = 440 feet
The distance from submarine to ship in oceans surface = 600 feet
We have to find the angle x.
The figure is given below:
Here, we have to use the tangents definition:
That is,
tan θ = opposite side / adjacent side
Here,
tan x = 440 / 600
We want to find x,
So,
x = tan⁻¹ (440 / 600)
x = tan⁻¹ (0.73333)
x = 40.28°
By taking nearest angle, we get x as 40°

Standing on the roof of a (42.0+A) m tall building, you throw a ball straight up with an initial speed of (14.5+B) m/s. If the ball misses the building on the way down, how long will it take from you threw the ball until it lands on the ground below? Give your answer in seconds and round the answer to three significant figures.
Answers
The time it would take from when you threw the ball until it lands on the ground below is equal to 2.16 seconds.
Given the following data:
Height of building = (42.0+A) m = (42.0+9) m = 51 m.
Initial speed of ball = (14.5+B) m/s = (14.5+8) m/s = 22.5 m/s.
Scientific data:
Acceleration due to gravity = 9.8 m/s²
How to determine the time?Generally speaking, when this ball is thrown straight up at a certain speed, it begins to slow down as a result of the effect of downward gravitational acceleration. Consequently, the ball reaches a maximum height where it can't go higher anymore and then starts to fall down due to gravity.
In order to determine the time it would take from when you threw the ball until it lands on the ground below, we would apply the second equation of motion:
S = ut + ½gt²
½gt² + ut - S = 0
Substituting the given parameters into the formula, we have;
0.5(9.8)t + 22.5t - 51 = 0.
4.9t + 22.5t - 51 = 0.
Next, we would solve the quadratic equation by using the quadratic formula:
[tex]t = \frac{-b\; \pm \;\sqrt{b^2 - 4ac}}{2a}\\\\t = \frac{-22.5\; \pm \;\sqrt{22.5^2 - 4(0.5)(-51)}}{2 \times 0.5}\\\\t = \frac{-22.5\; \pm \;\sqrt{506.25 + 102}}{2}\\\\t = \frac{-22.5\; \pm \;\sqrt{608.25}}{2}[/tex]
t = 2.16 or -47.16
Since the time cannot be negative, the value of t to three significant figures is equal to 2.16 seconds.

The height of the cannonball not equal to 0 when time equals 0 because initial height of the cannonball is above the ground
When time equals 0, why is the height of the cannonball not equal to 0?From the graph, we have the y-intercept to be
y-intercept = (0, y), where y > 0
This means that the graph starts above the origin
This in other words mean that the initial height of the cannonball is above the ground (e.g. it could be on a building)
Hence, the height of the cannonball not equal to 0 when time equals 0 because initial height of the cannonball is above the ground

You are installing 250 feet of PVC conduit. Each 100-foot section takes 1/2 can of PVC cement, and each 50-ft section takes 1/4 can. How much cement do you need? Your answer should be in the form of a mixed number, with any remaining fraction in its lowest terms.
Answers
While installing 250 feet of PVC conduit given the details we have in the question, The amount of cement needed is 1 1/4 can of PVC cement
How to find quantity of cement neededGiven data
PVC conduit required to be installed = 250 feet
Each 100-foot section takes 1/2 can of PVC cement
Each 50-ft section takes 1/4 can of PVC cement
250 feet will be split into two which is 200 feet and 50 feet. We solve for each separately then add up
solving for 200 feet
200 feet contains how many 100-foot, this is solved as follows:
= 200 / 100
= 2
And each 100-foot takes 1/2 can of PVC cement, therefore:
2 * 1/2 = 1
solving for 50 feet
50 feet takes 1/4 can of PVC cement
= 1/4
The sum: 1 + 1/4 = 1 1/4 ( mix number )

I am simply providing an explanation in case you need it
Step-by-step explanation:
The slope-intercept form equation of a straight line in 2D coordinates is given by y = mx + b
where m is the slope(rise/run) and b the y-intercept i.e. the y value where the line intersects the y axis
Given two points (x₁, y₁) and (x₂, y₂) on the straight line, we can compute the slope as follows
m = [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]
Two distinct points on the line are at (0, -3) and (5,-4)
[tex]m = \frac{-4 -(-3)}{5-0} = \frac{-4 + 3)}{5-0} = \frac{-1}{5} = - \frac{1}{5}[/tex]
So we know the equation to be
[tex]y = - \frac{1}{5}x + b[/tex]
To find b, take any point on the straight line, plug in y and x values in the above equation and solve for b
However, looking at the graph we see that the line crosses the y axis at
y = -3. So this is the value for the y intercept i.e. b
The equation of the line is therefore
[tex]y = - \frac{1}{5}x - 3[/tex]
an angle measures 101.4 less then the measure of supplementary angles. what is the measure of each angle
Answers
Answer:
39.3°, 140.7°
Step-by-step explanation:
supplementary angles means that together they have 180°.
so, when we have 2 angles, x and y.
x + y = 180
x = y - 101.4
using the second equation in the first
y - 101.4 + y = 180
2y - 101.4 = 180
2y = 281.4
y = 281.4/2 = 140.7°
x = y - 101.4 = 140.7 - 101.4 = 39.3°
so, the starting angle is 39.3°, and every supplementary angle is then 140.7°.

The probability of P(4) is 1/8. 12.5%, 0.125.
The probability of a number less than 10 is 8/8. 1 , 100%
The probability of a prime number is 1/2. 0.5. 50%.
What is the probability?Probability determines the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.
Probability of spinning 4 = number of possible outcomes / number of sections
1/8 = 0.125 = 12.5%
Probability of spinning a number less than 8 = possible outcomes / total sections
8/8 = 1 = 100%
Probability of spinning a prime number = number of possible outcomes / total sections

By eating one egg one cupcake and one slice of pizza a child consumes 303 mg of cholesterol. if the child eats three cupcakes in four slices of pizza he or she takes in 93 mg of cholesterol. by eating two eggs in 1 cup cake a child consumes 569 mg of cholesterol. how much cholesterol is in each item?
Answers
The amount of cholesterol that is in each is given as c = 19, E = 275 and P = 9
How to solve for the cholesterolWe have to define the variables as:
E + C + P = 303
3C + 4P = 93,
we have to make pizza, P the subject
4P = 93 - 3C,
P = (93 - 3C) / 4
2E + C = 569,
2E = 569 - C
E = (567-C) / 2
We have to form the equation
(569-C)/2 + C + (93-3C)/4 = 303
We have to multiply the equation by 4
(569-C)2 + 4C + 93-3C = 1212
1138 - 2c + 4c + 93 - 3c = 1212
-C = 1212- 93 -1138
-c = -19
hence c = 19 mg for 1 cupcake
E = (569- 19)/2
275 for 1 egg
P = (93-3C)/4
P = 93 - 57 / 4
= 36 / 4
= 9 for one pizza
Hence we would have c = 19, E = 275 and P = 9
19 + 275 + 9 = 303 (proves it to be correct)

Which of the following Statements are true?
Statement 1: A right triangle can be an equilateral triangle.
Statement 2: An equilateral triangle can be a right triangle.
Answers
Step-by-step explanation:
both statements are wrong.
a right (or right-angled) triangle has a 90° angle. that is all.
an equilateral triangle has 3 equally long sides.
but that also implies that the 3 angles must be equal too.
the sum of all angles in a triangle must be 180°.
if all angles are equally large, that means
180 = 3×angle
angle = 180/3 = 60°.
that means none of the angles can be 90°, so, no right-angled triangle can be equilateral.
and no equilateral triangle can be right-angled.
