A cell phone plan costs $150 to start, Then, thero is a $50 charge each month. What is
the total cost, y, for x months? Which equation match this situation Y=150-50x. Y=50x+150. Y=150x+50. -50x+150=y
Answer:
Y = 50x + 150
Step-by-step explanation:
50 per month (x = unknown number of months) === 50x
$150 is the starting charge (automatic +150)
Y = total cost
Y = 50x + 150

A rectangle with an area of 30 square units and a side length of 6 has another side
length of?
Answer:
The length of other side of rectangle is 5 units.
Step-by-step explanation:
We are given:
Area of rectangle = 30 square units
Length of one side = 6 units
We need to find the length of other side.
The formula used is: [tex]Area \ of \ rectangle=Length \times Width[/tex]
Considering length = 6, we need to find width.
Putting values in formula and finding length of other side
[tex]Area \ of \ rectangle=Length \times Width\\30=6 \times Width\\Width=\frac{30}{6}\\Width=5 \ units[/tex]
So, Width= 5 units
The length of other side of rectangle is 5 units.

Caitlin drew a scale drawing of the community park in her town. The actual
long.
What scale did Caitlin use to draw the park?
o 1 inch equals 4 feet
4 inches equal 4 feet
o 1 inch equals foot
4 inches equal 1 foot
Answer: 1 inch equals 4 feet
Step-by-step explanation:
By an online search, I´ve found that:
The park is 48 ft long.
Caitlin´s drawing is 12 inches long.
To find how much each inch represents, we need to take the quotient between those lengths:
48ft/12in = 4ft/in.
We also can write this amount as:
4 feet per inch.
This means that each inch represents 4 feets.
Then the correct option is the first one: 1 inch equals 4 feet

Remark
This is one of those questions whose answer is hidden by the sloppiness of the wording. You don't really know what the starting speed is at 129 feet. I am going to assume the submarine is constantly moving at the same speed.
Givens
d1 = 129
d2 = 229
t = 3 sec
formula
(d2 - d1) = r * t
solution
(229 - 129) = r * t
100 = r * 3
100/3 = r
33.3 feet/s = r
Caution
if you know what d = vi*t + 1/2*a * t^2 is, you could get this wrong. If you do know the formula, leave a comment below my answer.
Find the number, if 9/4 of it is 27
Answer:
12
Step-by-step explanation:
Let the required number be x
[tex] \frac{9}{4} \times x = 27 \\ \\ x = 27 \times \frac{4}{9} \\ \\ x = 3 \times 4 \\ \\ x = 12[/tex]
Answer:
I think 12 is the answer...
Step-by-step explanation:
27/1 divided by 4/9 (Multiply by the recipricol).
27/1 multiplied by 9/4 (Cross multiply/Use the butterfly method).
= 12/1 or 12

If I was asked to think of a number and multiply it by 2, I could
write this algebraically as 2x.
Write the following algebraically, using x as your unknown.
"I think of a number, take away 1 and multiply the result by 3."
Please answer
you didn't say what number you would think of
I'm guessing this is multiple choice but the formatting of the question is a bit hard to understand.
write it algebraically as 2x
2x just means multiply x by 2
The algebraic equation for the other example is 3(x-1) which is 3x - 3
This is not multiplying by two, so it is wrong.
On a school spirit day 257 students wore gold or black, 34 wore both gold and black, and 178 wore black. How many students wore only gold?
(Proof not needed, only LEGIT answers only please and thx)
Answer:
2 possible answers
Step-by-step explanation:
Assumption: 178 wore black (that means some may wear gold + black aka as long as they wore abit of black, it's counted):
since there are 257 students and 34 wore both gold and black, and 178 wore black, the number of students who wore only black = 178 - 34 = 144
no of students who wore only gold = 257 - 144 - 34 = 79
Assumption: 178 students wore ONLY black:
no of students who wore only gold: 257 - 178 - 34 = 45

Demi’s last 5 bowling scores were 68, 75, 90, 80. What was Femi’s mean score? A.72 B.75 C.77 D.79 D.
Complete Question:
Femi's last 5 bowling scores were 68, 75, 72, 90, and 80. What was Femi's mean score?
Answer:
Step-by-step explanation:
Given
Scores: 68, 75, 72, 90, and 80
Required
Determine the mean
The mean (M) of a data is calculated as thus:
[tex]M = \frac{\sum x}{n}[/tex]
Where
n = number of data.
In this case,
n = 5
and
[tex]\sum x[/tex] = sum of data
So, the formula becomes
[tex]M = \frac{68 + 75 + 72 + 90 + 80}{5}[/tex]
[tex]M = \frac{385}{5}[/tex]
[tex]M = 77[/tex]
Hence, the mean is 77

If g(x)= -3x^3+5x-3, then the slope of the line that is perpendicular to the tangent line at x=1 would be...
A. 4
B. -4
C. 2
D. -1/4
E. 1/4
The slope of the line that is perpendicular to the tangent line at x=1 is, [tex]\frac{1}{4}[/tex]
Option E is correct.
Slope of line:The derivative of given function with respect to x is known as slope of function.
Given function is, [tex]g(x)=-3x^{3}+5x-3[/tex]
Now differentiate the above function.
[tex]\frac{dg(x)}{dt}=-9x^{2} +5[/tex]
[tex]\frac{dg(x)}{dx}[/tex] at [tex]x=1[/tex] is,
[tex]\frac{dg}{dt} =-9(1)^{2}+5 =-4[/tex]
the slope of the line that is perpendicular to the tangent line at x=1 is,
Slope[tex]=-\frac{1}{dg/dx}=\frac{1}{4}[/tex]

The area of a triangle is 40 sq. inches. If the base of the triangle is 10 inches,
what is its height?
Answer:
8 inches
Step-by-step explanation:
Area of a triangle = 1/2 (b) (h)
so let's plug them in.
1/2( (10) (h)
now let's plug in 8
1/2 (10) (8)
10 times 8 equals 80
now
dividing it by 1/2 equals 40
therefore
it's the height is 8 inches
