Step-by-step explanation:
Trial and error
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The correct option is B.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
From the given equation that is true are,
A. 63 x 103 = 63,000
If we multiply 63 and 103 the product will be 6,489. Since the two sides of the equation are not true, therefore, the given equation is false.
B. 63 x 10,000 = 630,000
If we multiply 63 and 10,000 the product will be 630,000. Since the two sides of the equation are true, therefore, the given equation is true.
C. 63 x 102 = 630
If we multiply 63 and 102 the product will be 6,426. Since the two sides of the equation are not true, therefore, the given equation is false.
D. 63 x 1,000 = 6,300
If we multiply 63 and 1,000 the product will be 63,000. Since the two sides of the equation are not true, therefore, the given equation is false.
E. 63 x 105 = 6,300,000
If we multiply 63 and 105 the product will be 6,615. Since the two sides of the equation are not true, therefore, the given equation is false.
Hence, the correct option is B.

Step-by-step explanation:
In their latest play, the Giants lost another 5 yards. This is their third time losing 5
yards. The also gained 20 yards. Give an integer to represent how many yards the
Giants have gained or lost.
Using basic operations, it is found that the integer 5 represents that the Giants have gained 5 yards.
-----------------------------------------
There have been three plays where the Giants have lost 5 yards, thus, 3 times 5 is subtracted from their yardage total.There is one play where the Giants have gained 20 yards, thus, 20 yards are added to their yardage total.Using basic operations, we find the integer that represents the Giants yardage, as follows:
[tex]Y = -3\times5 + 20 = -15 + 20 = 5[/tex]
The integer 5 represents that the Giants have gained 5 yards.

When a measurement in inches is converted to centimeters, will the number of centimeters be grater or less than the number of inches? Explain.
Answer:
A centimeter is smaller than an inch, so a given length will have more centimeters than inches. This alone shows you that the NUMBER of cm units will always be greater than the number of inches, for a given measurement.
the number of gallons of bottled water N consumed by a person in one year is approximated by N=0.733t + 8.398, where t is the number of years since 1971. Predict the number of gallons consumed by a person in 1985.
Step-by-step explanation:
N = 0.733t + 8.398
N = 0.733(1971) + 8.398
N = 1,453.141
Step-by-step explanation:
Solution,
According to question,
N=0.733t + 8.398
When t= 1971, then
N=0.733×(1971) + 8.398
N=1453.141

What is the equation of the line that passes through the point (-7, 2) and has a
slope of -1
Answer:
y = -x - 5
Step-by-step explanation:
y = mx + b
slope = m = -1
y = -1x + b
y = -x + b
Plug in (-7, 2) for x and y, and solve for b.
2 = -(-7) + b
2 = 7 + b
b = -5
y = -x - 5

Based on the data which table shows a constant of proportionality of 3 for the ratio of Amos and guitars?
The speed of light in a vacuum is 2.998×108 m/s .
What is its speed in miles per minute (mi/min)?
To convert m/s to mi/min we have to find conversion factor first
1 mile = 1609.344 m
1m = 1/1609.344 miles
1 min = 60 s
1s = 1/60 min
Let’s put mi/min instead of m/s according to equations above
m/s = [1/1609.344 miles] / [1/60 min]
The conversion factor is
f = 60 / 1609.344
Now we can convert m/s to mi/min
V (mi/min) = 2.998 ∙ 108 m/s ∙ f = 2.998 ∙ 108 ∙ (60 / 1609.344) = 1.118 ∙ 107 mi/min
Answer: V = 1.118 ∙ 107 mi/min
Hope u have a good day of learning
1 mile = 1609.344 m
1m = 1/1609.344 miles
1 min = 60 s
1s = 1/60 min
Let's put mi/min instead of m/s according to equations above
m/s = [1/1609.344 miles] / [1/60 min]
The conversion factor is
f = 60 / 1609.344
Now we can convert m/s to mi/min
V (mi/min) = 2.998-108 m/s f= 2.998 108 (60/1609.344) = 1.118-107 mi/min
Answer: V = 1.118 - 107 mi/min

Enter and solve an equation to find the measurex of the congruent angles.
An equation is____
= 180.
The congruent angles each measure_____
o.
Answer:
26
Step-by-step explanation:
a triangle messures 180
you already have one angleso allyou do is subtract
180-128= 52
the since you are missing two angles all you do is divide that by 2
52/2=26
