Answer:
646.0 and 0.1 but you might have to keep the second one the same .125
Step-by-step explanation:
The nearest tenth is the number behind the decimal, and the number in the hundredths place is what you use to see if where to round it. If it is 4 or less keep it the same it it is 4-9 change is up by one.
EX: 1.58 you would round it to 1.6 because the number in the hundredths place is bigger than 4 so you up the number in the tenths place one.
The product of 645.99 and 0.125 would be 80.7 which is rounded to the nearest tenth.
What is the round to the nearest tenth of a number?The decimal point is followed by the number that is closest to the tenth, and the hundredth place number is used to determine whether or not to round the number. If it is four or fewer, leave it alone; if it is four to nine, move it up one.
We have to determine the product of 645.99 and 0.125
⇒ 645.99 × 0.125
⇒ 80.74875
Rounded to the nearest tenth, we get
⇒ 80.7
You would diminish the number in the tenth place by one because the number in the hundredth place is less than 5, thus you would round it to 80.7.
Therefore, the product of 645.99 and 0.125 would be 80.7 which is rounded to the nearest tenth.

Henry sends his hawk with a message to his uncle. The hawk flies out against the wind and returns with the wind, spending 3 hours on the whole trip. How far is Henry's uncle from Henry if the speed of the wind is 5 mph, and the hawk flies 50 mph in quiet weather?
Answer:
Distance between Henry and his uncle is 74.25km.
Step-by-step explanation:
Speed of Hawk with wind = 50+5
=55km/hr
Speed of Hawk against wind = 50-5
=45km/hr
we know that ,
[tex]Distance = speed \times time[/tex]
Let the distance between Henry and uncle is d,
According to the question ,
[tex]\frac{d}{55} + \frac{d}{45} = 3[/tex]
[tex]\frac{9d + 11d}{495} =3[/tex]
[tex]20d = 3\times 495[/tex]
[tex]d =\frac{3\times495}{20}[/tex]
d= 74.25km
Hence , the answer is 74.25km
The relation between speed, time, and distance is used. Then the distance between Henry's uncle from Henry is 74.25 miles.
What is speed?The distance covered in an hour is called speed. it is a scalar quantity.
What is relative speed?The concept of relative speed is used when two or more bodies moving with some speed are considered.
Henry sends his hawk with a message to his uncle.
The hawk flies out against the wind and returns with the wind, spending 3 hours on the whole trip.
We know the relation
[tex]\rm speed = \dfrac{distance }{time}[/tex]
Let the distance between Henry's uncle from Henry be x.
The time of the trip is during the traveling remains constant. That is
[tex]\rm T = T_1 + T_2\\\\T = \dfrac{x}{v_1} + \dfrac{x}{v_2}[/tex]
The speed of the wind is 5 mph, and the hawk flies 50 mph in quiet weather. Then we have
[tex]\rm v_1 = 50 - 5 = 45\\\\v_2 = 50 + 5 = 55[/tex]
Then
[tex]\begin{aligned} \rm \dfrac{x}{45} + \dfrac{x}{55} &= 3\\\\\rm \dfrac{9x + 11x }{495} &= 3\\\\\rm 9x + 11x &= 1485\\\\\rm 20x &= 1485\\\\\rm x &= 74.25 \end{aligned}[/tex]
Thus, the distance between Henry's uncle from Henry is 74.25 miles.

What is 73+84=. On Saxon math
Answer:
157
Step-by-step explanation:
You just have to take 73+84, and here is the equation.
73+84=157
OR
First, add the numbers in the ones place.
3+4=7
Now you know that the ones place is 7, we find the tens place.
7+8=15
Since only a 1-digit number can fill up a place, we bring the one over to the hundreds place.
Hence, the answer 157.
using the definition of multiplication to explain why a box that is 5 inches high 4 inches wide and 3 inches long has a volume of 5• (3•4) cubic inches explain the parentheses in the expression 5•(3•4)
Given:
Height of box = 5 inches
Breadth (width) of box = 4 inches
Length of box = 3 inches
Volume of box = 5 • (3 • 4) cubic inches
To find:
The explanation for the parentheses in the expression 5•(3•4)
Solution:
We know that,
Volume of a box is
[tex]Volume = length \times breadth \times height[/tex]
Area of a rectangle is
[tex]Area = length \times width[/tex]
Now,
Volume of box = 5 • (3 • 4) cubic inches
In this expression, (3 • 4) represents the product of length and with of the box. So, it means represents area of the base of box and after multiplying the base area with height we get the volume of the box.
Therefore, the parentheses in the expression 5•(3•4) represents the base area of the box.

4x+20 = 21+4x
we would subtract 4 on both sides to isolate 4 by it self.
subtract 4x on both sides but when we do we get 0 for x
4x-4x + 40 = 21 + 4x-4x
we get 40 = 21
So our answer is no Solution or unless your just tryning to find out that the total is with out x 40 = 21

We can use a ratio to solve
25 situp x situps
--------------- = --------------
12 pushup 60 pushups
Using cross products
25 * 60 = 12x
Divide each side by 12
25*60/12 = 12x/12

Answer:
-4Step-by-step explanation:
The billiard cue is 15 cm away from the table
This refers to coordinates of (15, 0)The billiard cue touches the table at a point 60 cm off the ground
This refers to coordinates of (0, 60)The slope is as per slope formula;
m = (60 - 0)/(0-15) = 60/ -15 = -4Thea answer is -4
Answer:
-4
Step-by-step explanation:
The foot of the billiard cue is 15 cm away from the table can be represented by the point (15, 0).
The top of the billiard cue touches the table at a point 60 cm off the ground can be represented by the point (0, 60)
The slope formula can be solve with the formula [ y2-y1/x2-x1 ]
