Answer:
3. 1.8
4. 66
Step-by-step explanation:
3.The common difference is the difference between a term and the one before it.
5 -3.2 = 1.8
The common difference is 1.8.
__
4.The 8th term is found by putting 8 where n is and doing the arithmetic.
a₈ = 10·8 -14
a₈ = 80 -14 = 66
The eighth term is 66.
_____
Additional comments
The difference is only "common" if all pairs of adjacent terms have the same difference. When that is the case, any pair of adjacent terms can be used to find the common difference. The arithmetic is probably easier using ...
6.8 -5 = 1.8

A bag of chips contains 621 calories and serves 4.5 people. How many calories are in each serving?
Answer:
138 calories/serving
Step-by-step explanation:
Find the unit rate, the measure of how many calories are in each serving:
621 calories
-------------------- = 138 calories/serving
4.5 servings
The number of calories are in each serving is 138.
Given that, a bag of chips contains 621 calories and serves 4.5 people.
What is the 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.
Number of calories in each serving = Total number of calories/Number of servings
= 621/4.5
= 138 calories
Therefore, the number of calories are in each serving is 138.

Answer:
1) 0.25
2) -2.342
Step-by-step explanation:
1 1/4% in simplest form
Answer:
It can be written as 0.25 in decimal form (rounded to 6 decimal places).
Step-by-step explanation:
Answer:
It is already in the simplest form, but you can convert It into many things.
Step-by-step explanation:
Make this into an improper fraction you: 1 x 4 + 1 then put the answer on the numerator and keep the denominator.
Mixed number = 5/4
Decimal = 1.25
because 1/4 = 0.25
and 1 is a whole number.

similar
Answer:
They are similar using the angle-angle property.
Step-by-step explanation:
Since you know that 2 of the angles are congruent, you can use this to prove triangle similarity.
By AA similarity, triangle PQR similar to triangle STU.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
The two given triangles PQR and STU.
Here, ∠P=63° and ∠R=45°
In triangle STU, ∠S=63° and ∠U=45°
Now, ∠P=∠S=63° and ∠R=∠U=45°
Since angles of triangle are congruent
By AA similarity, ΔPQR similar to ΔSTU
Therefore, triangles are similar.

*enter your lengths to the NEAREST TENTH
Answers:
FG = 8.5 GH = 11.4 FH = 17.5 JK = 11.4 KL = 17.5 JL = 8.5The triangles are congruent by SSS=======================================================
Explanation:
Use the distance formula to compute the length of each segment. For instance, the distance from point F to point G is the length of segment FG.
I'll show the steps on finding the length of FG
[tex]F = (x_1,y_1) = (-5,10)\\\\G = (x_2,y_2) = (-2,2)[/tex]
[tex]d = \text{distance from F to G}\\\\d = \text{length of segment FG}\\\\d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(-5-(-2))^2+(10-2)^2}\\\\d = \sqrt{(-5+2)^2+(10-2)^2}\\\\d = \sqrt{(-3)^2+(8)^2}\\\\d = \sqrt{9+64}\\\\d = \sqrt{73}\\\\d \approx 8.544\\\\d \approx 8.5\\\\[/tex]
The length of segment FG is approximately 8.5 units. The other side lengths are handled in the same way. As an alternative, you can use the pythagorean theorem.
---------------------
Once you determine all six lengths, note we have the following three pairs of corresponding congruent sides:
FG = JL = 8.5GH = JK = 11.4FH = KL = 17.5Because we have three pairs of equal sides, this means we can use the SSS (side side side) congruence theorem to prove the triangles are congruent. In other words, we have two identical triangles. One triangle is a rotated and reflected copy of the other.
The diagram is below.

Nathan usually drinks 33 ounces of water per day. He read that he should drink 59 ounces of water per day. If he starts drinking 59 ounces, what is the percent increase? Round to the nearest percent.
Step-by-step explanation:
33oz = 100%
1% = 100%/100 = 33/100 = 0.33oz
59 - 33 = 26oz increase
how many % are these 26oz compared to the original 33oz ?
we need to see how often 1% fits into 26oz.
26/0.33 = 78.78787878...%
rounded this means a 79% increase of drinking water.
