161.45
Jose’s explanation: I lined up the two decimals according to place value.
176.3
- 15.75
161.45
An’s explanation: I counted up from 15.75 to 176.3 to find the difference. I underlined each number I added on each line.
15.75 + 0.25 = 16
16 + 4 = 20
20 + 150 = 170
170 + 6 = 176
176 + 0.3 = 176.3
I rearranged the underlined numbers to make them easier to add: .
150 + 6 + 3 + 0.25 = 163.25

find the equation of the line that passes through a and b
8. A line passes through the points (0-2) and (0,5). Is it possible to write an equation of the line in
slope-intercept form? Justify your answer.
Answer: No
Step-by-step explanation:
There is no slope
It is not possible to write the equation of the line passing through (0, -2) and (0, 5), because slope is not defined.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.
Given that a line passes through two points (0, -2) and (0, 5).
Both the points are on Y axis.
Therefore the line is along the Y axis.
Slope of a line along the Y axis is not defined since the Y axis is making 90° with the X axis and tan 90° is the slope, which is not defined.
Or in other words, taking the given points,
slope = change in y coordinates / change in x coordinates
= (5 - -2) / (0 - 0)
= 7 / 0, not defined.
Hence the equation of the line along the Y axis cannot be written in the slope intercept form as the slope is undefined.

The formula t=√h/4 represents the time t in seconds that it takes an object to fall from a height of h feet. If a rock falls from a height of 125 feet, estimate how long it will take to reach the ground
Answer:
it would take 14mph
Step-by-step explanation:
A function assigns the values. The time it will take for the rock to reach the ground from a height of 125 feet is 2.795 seconds.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given that the formula t=√h/4 represents the time t in seconds that it takes an object to fall from a height of h feet.
Now, in order to calculate the time, it will take for the rock to fall from the height of 125 feet, simply substitute the height of the rock from which it is dropped in the formula given.
Therefore, the time it will take for the rock to reach the ground from a height of 125 feet is,
t = √h / 4
t = (√125) / 4
t = (5√5) / 4
t = 2.795 seconds
Hence, the time it will take for the rock to reach the ground from a height of 125 feet is 2.795 seconds.

I drive at 55 miles per hour, and my trip will takr 5 hours. Proportional or non proportional
Answer:
Proportional
Step-by-step explanation:
Here, we want to know if the distance at the given time will be proportional
What we will do here is to simply divide the distance by the time
Mathematically, that will be 55 miles/ 5 hours = 11 miles / hour
So this means that in an hour, 11 miles will be traveled
This expression is proportional

There were 28 boys on the boy's basketball team and 16 girls on the girl's basketball team last year. This year the number of boys decreased by 8% but the number of girls increased by 19%. Was there an increase or decrease in overall participation?
There is an increase in total participants.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
number of boys = 28
Number of girls = 16
Total participants = 28 + 16 = 44
Now, there is decrease in number of boys by 8%
= 28- 8% x 28
=28- 8/100 x 28
=28 - 0.08*28
=28 -2.24
= 25.76
and, there is 19% increase in number of girls
=16 + 0.19 x 16
=16 + 3.04
=19.04
So, total participants = 25.76 + 19.04
= 44.8
Hence, there is an increase in total participants.

How much does honey cost per ounce?
How much honey can you buy per dollar? Round to the nearest hundredth.
Answer: a. $0.45; b. 2.22 oz
Step-by-step explanation:
From the question, we are informed that acustomer buys 12 oz of honey for $5.40.
a. How much does honey cost per ounce?
To calculate this, we divide $5.40 by 12oz. This will be:
= $5.40/12
= $0.45
b. How much honey can you buy per dollar?
Since 1 ounce cost $0.45, the number of honey that can be bought for $1 will be:
= $1/$0.45
= 2.22 oz

What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
In any equilateral triangle, the three angles are of equal measure and they equal 60 degrees.
When we drop a perpendicular that is the height of the triangle we have a 30 -60 90 triangle.
The hypotenuse = 8
Let, perpendicular = a and base = 4
According to Pythagoras theorem,
A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
perpendicular²+base² = hypotenuse²
a² + (4)² = (8)²
a² + 16 = 64
a² = 64 - 16
a² = 48
a = √48
a = 4√3
Hence, the altitude of the triangle is 4√3
