Is 7164 divisible by 6?
yes?
no?
Answer:
yes
7164 is divisible bt 6
Answer:
Yes
Step-by-step explanation:
Any number will be divisible by 6 if they be divisible by 2 & 3
- we know 7164 is divisible by 2
- also any number which sum of their digits are divisible by 3, the number will be divisible by 3
in this case (7164) 7+1+6+4=18 & 18 is divisible by 3 so 7164 is divisible by 3 as well.
so 7164 is divisible by 6
What is the value of f(x) = 2 • 2x for f(–2)?

0.25
0.50
Step-by-step explanation:
[tex]f(x) = 2. {2}^{x} [/tex]
[tex]f( - 2) = 2. {2}^{ - 2} [/tex]
[tex]f( - 2) = 2. \frac{1}{ {2}^{2} } [/tex]
[tex]f( - 2) = \frac{2}{4} [/tex]
[tex]f( - 2) = 0,5[/tex]
The answer is D.
The value of f(x) = 2*[tex]2^{x}[/tex] when x = -2 is 0.5
What is a function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that a function, f(x) = 2*[tex]2^{x}[/tex]
f(-2) = 2*[tex]2^{-2}[/tex]
= 2*1/2²
= 2/4
= 0.5
Hence, The value of f(x) = 2*[tex]2^{x}[/tex] when x = -2 is 0.5

You need to hire an electrician to install new wiring in your house. Electrician A charges $75 plus 45 per hour. Electrician B charges $100 plus $40 per hour. (A). Write a system of equations for this situation. (B). For how many hours of work are the total costs the same for both electricians?
The equations take a linear form and are as follows; Part A.
Electrician A; c = 75 + 45h....eqn(1)Electrician B; c = 100 + 40h....eqn(2)Part B: It takes 5 Hours of work for the total costs to be the same.
The point at which the total costs are the same for both electricians is at;
75 + 45h = 100 + 40h45h - 40h = 100 - 755h = 25h = 5hours.

lennys lizard weighs 6 pound less than duble the laura's lizard lennys weighs 60 pounds find the weight of lauras lizard
(Me, going to answer the easy questions because hard ones give me headaches)
Alright, listen up.
Steps:
First step: 60 is Lenny's lizard weight. Since it said 6 pounds less than double the lizard weight, we are going to multiply 60 by 2, therefore it would be 120.
Next step: Now 6 pounds less, so we are going to subtract 6 from that 120. 120 - 6 = 114.
Last step...: Label/answer: Lenny's lizard weight is 114 pounds.
Answer:
Laura’s lizard weights 33 pounds
Step-by-step explanation:
Let 2x be Laura’s lizard and
Let 2x - 6 be Lenny’s lizard
We know Lenny’s lizard is 60 pounds. Now to find Laura’s , equate( 2x - 6 )to 60 and solve for x
60 = 2x - 6
x =33
Therefore 33 is the answer

The middle side of a triangle is half of 3 times the length of the shortest side. The longest side is 2 centimeters longer than the middle side. If the perimeter of the triangle is 18 centimeters what is the difference in the longest and shortest side
Answer:
The difference between the longest and shortest sides of the triangle is 4 cm.
Explanation:
Step Number One:
Let the shortest side of the triangle have a length of x.
The middle side of the triangle has a length that is half of 3 times the length of the shortest side. This can be written as 1/2*3x, which equals 3/2x.
The longest side of the triangle has a length that is 2 centimeters longer than the length of the middle side. This can be written as 3/2x + 2.
Step Number Two:
The perimeter of the triangle, which can be found by adding the lengths of all of the sides of the triangle, is 18 centimeters. This can be shown by the following equations:
Shortest Side + Middle Side + Longest Side = Perimeter
x + 3/2x + 3/2x + 2 = 18
4x + 2 = 18
4x = 16
x = 16/4
x = 4
Step Number Three:
This means that the shortest side of the triangle has a length of 4 centimeters and the longest side of the triangle has a length of 8 centimeters.
8 cm - 4 cm = 4 cm

4. On a scale drawing of a park, the sand box is 2 inches wide. The actual sand box is 8 feet wide.
What is the scale of the drawing?
1 in. = 4 ft
O 1 in = 6 ft
O4 in = 1 ft
04 in = 6 ft
Finish Cancel
Answer:
1 inch = 4 feet
Step-by-step explanation:
[tex]\frac{2 inches}{8 feet} = \frac{1 inch}{4 feet}[/tex]
If we divide the given numbers by two (dividing on both sides keeps the equation true), we get 1 inch/4 feet. This tells us that on the scale, one inch is representative of four feet.
