Answer: 213/40 or 5.325
Step-by-step explanation:
We can find common denominators for 8 1/5 and 2 7/8.
The Lowest Common Denominator for 8 1/5 and 2 7/8 is 40.
8 1/5 = 41/5 = 328/40.
2 7/8 = 23/8 = 115/40.
Now we can subtract.
328/40 - 115/40 = 213/40.
Therefore, the answer is 213/40 or 5 13/40.

35 * 10 = 350
Step-by-step explanation:
We have 5 * 70 split up into multiple ways, and we need to provide an answer at the end of it.
5 * 70 = 5 * (__ * 10)
We have to equal the value of 5 * 70 by inputting the missing number.
What times 10 equals 70?
7.
5 * 70 = (5 * __) * 10
This goes for the same as the one before, what times 5 equals 5 * 70 to the same amount?

5 * 70 = __ * 10 = __
Now for the final part, we take the information from before and implement to here, what is 5 * 7?

A highway inspector needs an estimate of the mean weight of trucks crossing a bridge on the interstate highway system. she selects a random sample of 49 trucks and finds a mean of 15.8 tons with a sample standard deviation of 3.85 tons. the 90 percent confidence interval for the population mean is:
Answers
Answer:
14.90 to 16.70 tons
Step-by-step explanation:
We are given;
Sample size; n = 49
Mean; x¯ = 15.8
Sample standard deviation; s = 3.85
At 90% Confidence interval, z = 1.645
Formula for confidence interval is;
CI = x¯ ± z(s/√n)
Thus;
CI = 15.8 ± 1.645(3.85/√49)
CI = 15.8 ± 0.90
CI = 14.90 to 16.70 tons

An airplane is currently flying at an altitude of 37,000 feet. The airplane is scheduled to land at an airport 100 miles
away. Find the average angle at which the airplane must descend for landing. Round your answer to the nearest
degree.
Answers
Answer:
4degrees
Step-by-step explanation:
Given the following
Height of the airplane = 37000feet
distance covered on landing = 100miles = 100(5280)
distance covered on landing = 528,000feet
Using the SOH CAH TOA
sin theta = opposite/hyp
sin theta = 37000/528000
sin theta = 37/528
theta = arcsin (37/528)
theta = 4 degrees
Hence average angle at which the airplane must descend for landing is 4degrees

how to write an equation
Answers
Answer:
Step-by-step explanation:
An equation is like a sentence, just using a different language. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. It's up to you to learn this language. However, once you know it, you can write in this language! You, too, can write algebraic equations.
Parts of a Mathematical Equation
A mathematical equation, also known as a statement, shows that two separate expressions are equal. The two expressions are usually connected by the "equal-to" (=) sign. You can find the expressions in a mathematical statement by looking at the left-hand side and the right-hand side of the equation, using the = sign as the point of reference.
Example: 2x + 3 = 11
It can be helpful to view equations as a scale in which weights are used to keep it balanced. The scale is balanced when what is placed on the right-hand side is equal in weight to what is on the left-hand side. Solving an equation can also be thought of in terms of adding weight to the left or right-hand side of the scale to balance it out.
Finding the solution to the equation involves manipulating the weights. Whatever is done on the right-hand side of the scale must also be done on the left-hand side to keep the scale balanced.
Your tools for this happen to be, most commonly, addition, subtraction, multiplication, or division.
Answer:
An equation uses symbols and numbers there are SO many equations you could make for example an easy one 6 x 5 = 30 there are two numbers you multiply to get a product. Whenever you write an equation you always put an equal sign which is this: = . This shows what you get from the equation. There are main parts the =, +, -, x, ÷ . All represent what you do to the two numbers you put on both sides of it.

The value of x is 9.
To find x
2x+9≤27Subtract 9 from both sides we get,
2x ≤18
Divide 2 from both sides,

London's family took a road trip to the Grand Canyon. London fell asleep 61% of the way through the trip. If London fell asleep after they had travelled 305 miles, what was the total length of the trip?
Answers
Answer: 782.05 miles.
Step-by-step explanation: Percentage is a ratio expressed as fraction of 100, in other words, 61% is represented as [tex]\frac{61}{100}[/tex] or 0.61.
London slept 61% of the journey, so it means he was awake for 39% of the journey. Now the total trip is [tex]\frac{100}{100}[/tex] or 1, so the relationship will be
0.39 ---- 305 miles
1 ----- x
[tex]x=\frac{305}{0.39}[/tex]
x = 782.05
The total length of the trip was 782.05 miles.

System of inequalities
ASAP I ONLY HAVE 15 MINS WILLING TO GIVE 20 POINTS
Answers
Answer:
y > x - 4
x > 3
Step-by-step explanation:
The system of inequalities need to represent the overlapped, black area, so you need to write an inequality for each of the two lines shown.
To find out whether you should be using a >, <, ≤, or ≥, identify on the graph first:
The vertical line is shaded to the right of the line. The line is also dashed, so it should be a >.
The sloped line is shaded above the line. The line is also dashed, so it should be a >.
Then, find the slopes of the lines.
Refer to the sloped line as Line 1 and the vertical line as Line 2.
The slope of Line 1 is 1. It's y-intercept (where the line crosses the y-axis) is -4.
So: y = x - 4
Replace the = with >.
y > x - 4
Line 2 is unidentified, so you can see that it's x = 3. Replace the = with >.
x > 3
You can always check by plugging in a point from the overlapped area, like (4, 1).
(4, 1)
y > x - 4
1 > 4 - 4
1 > 0
x > 3
4 > 3
These statements are true.
