6y-3y if y= 1
need help?
Answer:
3
Step-by-step explanation:
Let us plug y into the equation:
6*1-3*1=
6-3=
3
I hope this helps! :)
Answer:
3
Step-by-step explanation:
you need to substitute the y for 1 because y=1
so it'll look something like this 6(1) - 3(1)
The y is touching the 6 and -3 so that means you need to multiply.
So 6(1) - 3(1) = 6-3 = 3

in Ethiopia there are 20 premier league soccer teams. in one round how many games are there?
Answer:
190 games
Step-by-step explanation:
²⁰C₂ = 20!/[(20 - 2)! * 2!] = 190
The number of games that should be there is 190 games.
Calculation of the number of games:Since in Ethiopia, there are 20 premier league soccer teams.
So here we used the combination
i.e.
= ²⁰C₂
= 20!/[(20 - 2)! * 2!]
= 190
A combination refers to the mathematical technique where it measures the no of possible arrangements where the selection order should not be considered. It can be selected in any sequence.
hence, we can conclude that The number of games that should be there is 190 games.

Mario is planning a charity dinner. Each table costs $50 and each chair costs $7 to rent. The other costs of the dinner are $475. Let t represent the number of tables and let c represent the number of chairs. Write the expression to represent the situation and explain how you got your answer.
Answer:
Cost of Dinner = 50t + 7c + 475
Step-by-step explanation:
"t" represents tables and they cost $50 each, so the algebraic expression would be "50t" ($50 times the number of tables).
Same applies to chairs; "7c" ($7 times the number of chairs).
The $475 represents the other costs added to the total.
So the expression to represent this problem would be at the total cost of the charity dinner is 50t (50 dollars per table) plus 7c (7 dollars per chair) and $475 for other costs.
A large spherical structure has a 37.5-foot radius. The sphere is covered with panels. If each panel has an area of about 49 ft2, approximately how many panels would be needed to cover the entire sphere?
360
940
17,660
310,000
Answer:
Option (1)
Step-by-step explanation:
Radius of the spherical structure = 37.5 feet
Surface area of each panel = 49 square feet
Sphere is covered with panels.
Therefore, area of the panels needed = [tex]\frac{\text{Total surface area of the sphere}}{\text{Area of one panel}}[/tex]
Surface area of the sphere = 4πr²
Here 'r' = radius of the sphere
For a sphere having radius 'r' = 37.5 feet,
Surface area of the sphere = 4π(37.5)²
= 17671.5 feet²
Number of panels required to cover the sphere = [tex]\frac{17671.5}{49}[/tex]
= 360
Therefore, Option (1) will be the answer.

Any help appriciated and needed Thank you!! Will also be marking brainliest
Answer:
4. 380.13 cm²
5. 706.86 cm²
6. 12.57 cm²
Step-by-step explanation:
4. Area of circle = πr²
radius (r) = ½ of diameter = ½ of 22 cm = 11 cm
Area = π*11²
Area = 380.13 cm²
5. Area of circle = πr²
radius (r) = ½ of diameter = ½ of 30 cm = 15 cm
Area = π*15²
Area = 706.86 cm²
6. Area of circle = πr²
radius (r) = ½ of diameter = ½ of 4 cm = 2 cm
Area = π*2²
Area = 12.57 cm²
Find m∟1 and m∟2. Tell which theorem can be use
Answer: Angle 1 = 150 - corresponding angles
Angle 2 = 150 - alternate exterior angles
Step-by-step explanation:
To find the measure of angles ∠1 and ∠2, we are using vertical angle theorem and corresponding angles concept.
From the given figure measure of one of the angle is 150°.
What are angles of parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.
Corresponding angles are angles that occur on the same side of the transversal line and are equal in size. They are either both obtuse or both acute.
Here, ∠1 = 150° (Corresponding angles)
∠1 =∠2 = 150° (Vertically opposite angles are congruent)
To find the measure of angles ∠1 and ∠2, we are using vertical angle theorem and corresponding angles concept.
