Simplify the expression.
7(a + 3b) + 2(a - b)
A.18a + 18b
B.9a + 23b
C.9(2a + 2b)
D.9a + 19b
Answer:
D.9a+19b
Step-by-step explanation:
7(a+3b)+2(a-b)
7*a=7a
7*3b=21b
2*a=2a
2*-b=-2b
7a+21b+2a-2b
7a+2a=9a
21b-2b=19b

Find the circumference of a roll of tape whose diameter is 5 cm.
Answer:
15.7 cm
Step-by-step explanation:
Circumference= Diameter * Pi
Hence,
Circumference of the circle= 3.14 * 5
=15.7 cm
Answer:
[tex]\huge{\boxed{\sf{15.71 cm}}}[/tex]
Step-by-step explanation:
Given :
diameter ( d ) = 5 cm
radius ( r ) = [tex]\frac{5}{2}[/tex] = 2.5 cm
Finding the circumference of a roll of tape:
Circumference of a circle = 2πr
circumference = [tex]2 * \frac{22}{7} * 2.5[/tex]
circumference = 15.71 cm
Hope I helped!

Chloe went on vacation with her family and they decided to swim with the dolphins there's a flat fee of $75 for the family to rent wet suits additionally a cost an extra $189.99 per person to swim with the dolphins the families total cost was $1024.99 how many family members went swimming with the dolphins
Answer:
5 family members went swimming with the dolphins.
Step-by-step explanation:
From the information given, you can say that the total cost for the family to swim with dolphins is equal to the flat fee for the family to rent wet suits plus the extra cost per person for the number of family members:
1024.99=75+189.99x, where x is the number of family members
Now, you can solve for x:
1024.99-75=189.99x
949.99=189.99x
x=949.99/189.99
x=5
According to this, the answer is that 5 family members went swimming with the dolphins.
Josh practices free throws during basketball practice on Monday and Tuesday. On Monday, he attempts 15 free throws and 6 basketballs went in the basket. Over both days, Josh wants at least 80% of his balls to go in the basket. If he makes every free throw on Tuesday, what is the minimum number of free throws required on Tuesday to reach his goal?
Answer:
he has to make 12 shots
Step-by-step explanation:
Josh will have to make a minimum of 12 shots to the basket to reach his goal on Tuesday. Basically, 12 shots are 80% of 15 shots he decides to take every Monday and Tuesday.
Baskets are said to be done when the basketball ends up passing through the basket in the opponent's side of the basketball field. However, Josh is practicing his free throws here.Josh has set a goal to himself that at least 80% of his shots should be basket. Considering that he takes 15 throws on Monday the calculation of baskets will be done as below.[tex]\rm Josh's goal= \dfrac{80}{100} x 15[/tex]
So the Josh's required free throws on Tuesday will be,[tex]\rm Josh's\ goal = 12[/tex]
It can be concluded that Josh will have to make at least 12 of his 15 free throws into the basket on Tuesday to achieve his set goal of 80%.Hence, Josh will have to make 12 free throws into the basket on Tuesday to be able to score at least 80% of his free throws as baskets.
