Answer:
An angle that measures exactly 180° is known as a <u>straight</u> angle
Step-by-step explanation:
A straight angle is basically just a line. It is equal to two right angles (which are 90 degrees) and it is also half of a circle.
I hope this was helpful! If you need any more information on straight angles or any other angles, let me know! Have a lovely day! :)
Answer:
The answer is 7
Step-by-step explanation:
Because 7 times 3 will give you 21, just divide 21 by 3.
Answer:
1 quart blue + 1 1/2 quart red
Step-by-step explanation:
Given:
Ratio of blue paint : red paint = 1/3 : 1/2
simplifying this ratio into whole numbers by multiplying both sides by 2 and 3, we get:
(1/3) x (3x2) : (1/2) x (3x2)
2 : 3
From this we can determine the fractions of red and blue paint used in any total purple mix
fraction of blue paint = 2/(2+3) = 2/5 of purple mix
fraction of red paint = 3/(2+3) = 3/5 of purple mix
we are given that we want to make 2 1/2 (= 5/2) quarts of purple paint
hence
amount of blue paint
= fraction of blue paint in purple mix x total amount of purple paint
= (2/5) x (5/2) = 1 quart
amount of red paint
= fraction of redpaint in purple mix x total amount of purple paint
= (3 /5) x (5/2) = 3/2 quart = 1 1/2 quart
With six students absent, there are 26 students, so 78/26 = 3 colored pencils for each student.
Selection B is appropriate.
Answer:
A = $3094.58
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Simple Interest Rate Formula: A = P(1 + r)ⁿ
- A is the final amount
- P is the principal amount
- r is the rate
- n is the time (in years)
Step-by-step explanation:
<u>Step 1: Define variables</u>
A = ?
P = 3020
r = 0.05
t = 6 months = 0.5 years
<u>Step 2: Solve for </u><em><u>A</u></em>
- Substitute: A = 3020(1 + 0.05)^0.5
- Add: A = 3020(1.05)^0.5
- Evaluate: A = 3020(1.0247)
- Multiply: A = 3094.58
And we have our final answer!
