Answer:
a = 3.6
Step-by-step explanation:
[tex] \frac{2}{3} (6a + 9) = 20.4 \\ \\ \bigg( \frac{2}{3} . \boxed{6a} \bigg) + \bigg(\boxed{ \frac{2}{3}} . {9} \bigg) = \boxed{ 20.4} \\ \\ (2.2a) + (2.3) = 20.4 \\ \\ 4a + 6 = 20.4 \\ \\ 4a = 20.4 - 6 \\ \\ 4a = 14.4 \\ \\ a = \frac{14.4}{4} \\ \\ a = \boxed{3.6}[/tex]
= 4a+6=20.4
= a=14.4/4
= a=3.6

I need to know how to find the measure of angle a.
Answers
Answer:
90°
Step-by-step explanation:
We need expressions for the measures of the three interior angles. Then we add them and set the sum equal to 180. Then we solve for x. Finally, we use the value of x in x + 100 to find the measure of angle A.
Let's first find an expression for each angle.
Angle A: m<A = x + 100
Bottom left angle: The interior angle is vertical to the angle measuring x + 60, so the interior angle also measures x + 60.
Bottom right angle: Let's call the measure of the interior angle y. y and the angle measuring 140° are supplementary, so y + 140 = 180; y = 40.
Now that we have expressions for the three interior angle measures, we add them and set the equal to 180.
(x + 100) + (x + 60) + 40 = 180
x + 100 + x + 60 + 40 = 180
2x + 200 = 180
2x = -20
x = -10
The measure of angle A is x + 100, and x = -10
m<A = x + 100 = -10 + 100 = 90

Which of the following equations best verifies the reasonableness of the solution for
log, 128 = x?
Answers
The equations best verifies the reasonableness of the solution will be log₃ 2187 = 7 and log₃ (3⁷) = 7. Then the correct options are A and E.
What is a logarithm?Exponents can also be written as logarithms. A number base logarithm is similar to some other number. It is the exact inverse of the exponent expression.
The equation is given below.
log₃ x = 7
Take anti-log on both side, then we have
x = 3⁷
x = 2187
Then the equation is satisfied by 2187. Then we have
log₃ 2187 = 7
log₃ (3⁷) = 7
Then the correct options are A and E.
The complete question is attached below.

a wedding planner accounts for 8 chairs at every round table. how many tables will be needed to seat 175 people?
Answers
Answer:
21.875
Step-by-step explanation:
you do 175 divided by 8
The required number of tables to seat 175 people are 22.
What is division?Division is defined as the splitting of a large group into smaller groups such that every group will have an equal number of items.
it is given that,
Number of chairs for 1 table = 8
Number of people to seat = 175
Therefore chairs = 175
Since 8 chairs are required at every round table
Therefore,
Number of tables to seat 175 people = Number of people to seat/Number of chairs for 1 table
⇒ Number of tables to seat 175 people = 175/8
⇒ Number of tables to seat 175 people = 21.87 ≈ 22 tables
Thus, the required number of tables to seat 175 people are 22.

Mariel deposited ₱6,500.00 in an account that offers 5% interest compounded semi-annually. How much money is in his account at the end of five years?
Answers
Answer:
The amount is 8,322
Step-by-step explanation:
To get this , we are going to use the compound interest formula
A = P( 1 + r/n)^nt
A is the amount we are calculating
P is the amount deposited = 6,500
r is the interest rate = 5% = 5/100 = 0.05
n is the number of times per year the interest is compounded
= 2 since it is semi-annually
t is the number of years = 5
Substituting these values, we have it that ;
A = 6,500(1 + 0.05/2)^10
A = 6,500(1.025)^10
A = 8,322

What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
If you spent 58 minutes doing English homework and 47 minutes doing math homework.
Now,
Since, The time for doing English homework = 58 minutes
And, The time for doing Math homework = 47 minutes
So, The time more to spend doing English homework = 58 - 47
= 11 minutes
Thus, There are 11 minutes more time to spend doing English homework.
