Can you show me how to solve this problem: a. ) 16=4 to the 3rd power x -7

1 answer:

7 0

We assume you mean
$\ \ \display{16=4^{3x-7}}$
This is solved by writing 16 as a power of 4 and equating exponents.
$\ 4^{2}=4^{3x-7}$
2 = 3x - 7 . . . . . equate exponents
9 = 3x . . . . . add 7
3 = x . . . . . divide by 3

The solution is x = 3.

Answer: 12 tables minimum, 15 max.

Step-by-step explanation:

If you substitute 14 in an inequality

200c + 500t >= 8800

200(14) + 500t and solve for t, you get t must be at least 12.

C +T cannot exceed 29

So figure 14 +12 =26 so they could sell up to 15 tables and not go over 29.

You will have to enter the t values 12,13,14,15

the height of an equivalent triangle is 15cm and it's perimeter is 36cm find the area of the triangle

OlgaM077 [116]

Answer:

The area is 72 cm².

Step-by-step explanation:

Since it is equivalent triangle

h = b

so,

b + b + b (since all sides are equal)= 36 cm

3b = 36 cm

or, b = 36/3

so, b = 12 cm

area of triangle = (1/2)×b×h

= (1/2)×12cm×12cm

= 6cm × 12cm

= 72 cm²

A high school football team won 80% of the games they played. If they played 35 games, how many games did they win?

crimeas [40]

Step-by-step explanation:

$formuale \\ \%wom = total \: win \: \times 100\% \div total \: matches \: played$

let x be total much won

$80\% = x \times 100\% \div 35 \\ x= 35 \times 80 \div 100 \\ x = 7 \times 4 \\ x = 28$

so they team had won 28 matches.

I hope the team has best players : )
