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.

Which equation, in slope-intercept form, matches the equation shown?
a line that goes through the points (0, -4) and (6, -9)
Question 4 options:
y=47x−4
y=56x+1
y=−56x−4
y=−47x+1
Please help!
Answer: i think it is y=−56x−4
Step-by-step explanation:
The equation in the slope intercept form which passes through the points ( 0, -4 ) and ( 6 , 9 ) is y = (-5 / 6)x - 4.
The correct answer is Option C.
Given data:
To find the equation of a line in slope-intercept form (y = mx + b) that passes through the points (0, -4) and (6, -9), we need to determine the slope (m) and the y-intercept (b).
First, calculate the slope (m):
m = (change in y) / (change in x)
m = (-9 - (-4)) / (6 - 0)
m = (-9 + 4) / 6
m = -5 / 6
Now that we have the slope, we can use one of the given points (let's use (0, -4)) to solve for the y-intercept (b):
-4 = (-5 / 6) * 0 + b
-4 = b
So, the y-intercept (b) is -4.
Now, we can write the equation of the line in slope-intercept form:
y = (-5 / 6)x - 4
Hence, the equation of the line is y = (-5 / 6)x - 4.

Answer:
1.375 = x or 1.4 = x
If you need to round it then it would be 1.4 = x

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

At Crescent High School, 108 students plan on going to an in-state college and 63 students plan on going to an out-of-state college. What is the ratio of students planning on going to an in-state college to students planning on going to an out-of-state college?
A.
12:7
B.
108:1
C.
7:12
D.
1:108
Explanation:
The ratio we want to find can be thought of in the form in:out
We list the number of "in-state" people first followed by the "out-of-state" people next. A colon separates the two values. So we have the initial ratio of 108:63
Divide both parts by the GCF 9
108/9 = 1263/9 = 7The ratio 108:63 fully reduces to 12:7 meaning there are 12 in-state students for every 7 out-of-state students. The order is important because 7:12 would be incorrect and imply we had 7 in-state vs 12 out-of-state.

The corner section of a football stadium has 6 seats on the first row. Each row after that has an additional 3 seats. How many seats would be on the 20th row?
32
63
103
342
9514 1404 393
Answer:
63
Step-by-step explanation:
The number of seats in a row will give an arithmetic sequence:
6, 9, 12, 15, ...
The first term is 6; the common difference is 3. The general term is ...
an = a1 +d(n -1) . . . . . . n-th term of sequence with first term a1, difference d
The 20th term of the sequence is ...
a20 = 6 +3(20 -1) = 6 +57 = 63
There would be 63 seats on the 20th row.
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

3. A gym charges a fee of $15 per month plus an additional charge for every group class
attended. The total monthly gym cost T can be represented by this equation: T = 15+c*n,
where c is the additional charge for a group class, and n is the number of group classes
attended
Which equation can be used to find the number of group classes a customer attended if we
know c and T?
a. n = I - 15
N
b. n=1 – 150
c. n = (T - 15) - C.
(T-15)
d. n=
1
Answer:
Option D) [tex]\huge\sf{n\:=\:\frac{(T\:-\:15)}{c}}[/tex]
Step-by-step explanation:
Given the equation, T = 15 + c × n, where:
T = represents the total monthly gym cost
c = represents the additional charge for a group class, and
n = represents the number of group classes attended
Solution:In order to determine which equation can be used to find the number of group classes a customer attended, if there are given values for c and T, we must isolate the variable, n algebraically.
The first step is to subtract 15 from both sides:
T = 15 + c × n
T - 15 = 15 - 15 + c × n
T - 15 = c × n
Next, divide both sides by c to isolate n :
[tex]\huge\mathsf{\frac{({T\:-\:15})}{c}\:=\:\frac{{c\:\times\:n}}{c}}[/tex]
[tex]\huge\sf{n\:=\:\frac{(T\:-\:15)}{c}}[/tex]
Therefore, the correct answer is Option D) [tex]\huge\sf{n\:=\:\frac{(T\:-\:15)}{c}}[/tex].

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
