It would have been better if he drew it like one of these because they're more standard in math. It's also easier to identify that it's supposed to be a right triangle because that's essentially what it is. (45+45=90 and 90 +90= 180).
A factory can make 3,848 pencils in one hour. Which is the best estimate of how many pencils can be made in 4 hours?
Answer:
15,392 pencils.
Step-by-step explanation:
If a factory can make 3,848 pencils in an hour, then the factory can make 15,392 pencils in 4 hours.
Simply multiply 3,848 by 4.
[tex]3,848*4=15,392[/tex]
Therefore, the factory can make 15,392 pencils in 4 hours.
Answer:
Approximately 16,000 pencils
Step-by-step explanation:
Round 3,848 pencils to the nearest thousand.
That'll turn 3,848 to 4,000.
Since it's 4 hours:
4,000 * 4 = 16,000 pencils

Mrs. Hamilton tallies her students test grades in the table below. What percent of the class received an A or a B?
Answer:
The correct answer would be 30%
Hope this helps!
Mark me brainliest if I'm right :)
The required percentage of the class to receive by A or a B is 40%. Option D is correct.
What is the percentage?A percentage is a number or ratio expressed as a fraction of 100. It represents a proportion or share of a whole that is divided into 100 equal parts. Percentages are often used to express changes, comparisons, or proportions in various fields such as finance, economics, and statistics.
Following the table,
The total tally is = 30
Total tally of A or B = 7 + 5 = 12
The percentage of A or B in the tally is given as,
= 12/30 * 100%
= 40%
Thus, the required percentage of the class to receive by A or a B is 40%. Option D is correct.

Can someone help me I don't know what n represents
Answer:
n=7
Step-by-step explanation:
6(n-3) - 2n=10
Distribute
6n - 18 -2n = 10
Combine like terms
4n -18 = 10
Add 18 to each side
4n-18+18 = 10+18
4n = 28
Divide by 4
4n/4 = 28/4
n = 7
i do t really know how to do this pls help
Answer:
for number 5 Subtract 18 from both sides of the equation
4+18−18=30−18
for number 1 Subtract 7 from both sides of the equation
so number 3 subtract 3 from each side and so on hope it helps
im not sure how to explain it but--
for example.. the first one
1) y + 7 = 12
first, you subtract 7 from both sides
so-- you'll subtract 7-7 on the left and 12-7 from the right
now, you have y by itself since 7-7 = 0
y = 12-7, or y = 5
also its important to note that when the equation is like 2) and uses subtraction (x-4) instead of addition (y +7)-- then you add to both sides
so for 2)-- you'd add 4 to both sides for 4 to cancel out to equal 0
your goal is always to isolate the variable on one side

Find the midpoint of the line segment whose endpoints are the given points. (-24.6, 38.1) and (-25.7, -17.7)
Answer:
Midpoint is[tex](-25.15,10.2)[/tex]
Step-by-step explanation:
A line segment refers to line that has two endpoints.
Let [tex](a,b),(c,d)[/tex] be the endpoints of a line segment.
Midpoint of the line segment is given by [tex](\frac{a+c}{2} ,\frac{b+d}{2})[/tex]
Take the given points as follows:
[tex](a,b)=(-24.6,38.1)\\(c,d)=(-25.7,-17.7)[/tex]
Midpoint of a line segment [tex]=(\frac{-24.6-25.7}{2},\frac{28.1-17.7}{2})[/tex]
[tex]=(\frac{-50.3}{2} ,\frac{20.4}{2} )\\=(-25.15,10.2)[/tex]
