Answer:
83 cm
Step-by-step explanation:
let's make an equation for this situation. The plant starts at 8 cm and grows 3 cm every week. If x represents time in weeks and y represents height in cm, then:
y = 8+3x
filling in 25 for x, we find that:
y = 8+75
y = 83 cm
Answer:83
Step-by-step explanation:
25 x 3 = 75
75 + 8 = 83

If 7 shirts = 32.90 then (32.90/7) x 8 = 37.60
Mark would like to build a rectangle frame. The dimensions of the frame are unknown, but the perimeter of the frame must be 80 yards. The length of the frame is six less than the width. What is the length of the frame?
Answer:
The length of the frame is 17
Step-by-step explanation:
The computation of the length of the frame is shown below:
As we know that
The perimeter of a rectangle is
= 2 (length + width)
where,
let us assume the width be x
So, the length is x - 6
And, the perimeter is 80 yards
So, now put these values to the above formula
80 yards = 2 (x - 6+ x)
80 yards = 2 (2x - 6)
80 yards = 4x - 12
92 = 4x
x = 23
So, the length of the frame is
= 23 - 6
= 17

Answer:
5x^2 + -3
Step-by-step explanation:
For this problem, we will simply simplify the expression by combining like terms.
(-3x^3 - 7x^5 - 3) + (5x^2 + 3x^3 + 7x^5)
= 7x^5 + -7x^5 + 3x^3 + -3x^3 + 5x^2 + -3
= 0 + 0 + 5x^2 + -3
= 5x^2 + -3
Thus, the simplified expression is 5x^2 + -3.

What is the equation of a horizontal line passing through the point (-3, 8)?
A: x=-3
B: y=8
C: x=5
D: y=-11
Answer:
B
Step-by-step explanation:
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 3, 8 ) with y- coordinate of 8, thus
y = 8 ← equation of horizontal line
A truck parked on the street is 56 m from the base of the apartment building on the right. The angle of elevation from the truck to the top of the building is 40°. The parked truck is 49 m from the base of the apartment building on the left. The angle of elevation from the truck to the top of that building is 50°. Which building is taller?
Answer:
The building to the left is taller.
Step-by-step explanation:
Building on right:
tan 40° = a/56
a = 56 tan 40° = 46.99
Building on left:
tan 50° = b/49
b = 49 tan 50° = 58.40
The building to the left is taller.

Answer:
x = 18
Step-by-step explanation:
Given:
a = 2x +3b = 4x - 7Finding x for which 3b = 5a:
3b = 5a3(4x - 7) = 5(2x + 3)12x - 21 = 10x + 1512x - 10x = 15 + 212x = 36x = 36/2x = 18Answer:
x = 18
Step-by-step explanation:
Plug in 4x-7 for b and 2x+3 for a in 3b = 5a
3(4x-7) = 5(2x +3)
Solve for x:
12x-21 = 10x+15
2x = 36
x=18
how does 1/12 - 5/6 = 9/12 um tring to learn how to add this like ?
Answer:
see below
Step-by-step explanation:
1/12 - 5/6 = -9/12
We need to get a common denominator of 12
1/12 - 5/6*2/2 = -9 /12
1/12 - 10/12 = -9/12
Since the denominators are the same, we can subtract the numerators
1-10 = -9
-9/12 = - 9/12
We can simplify -9/12 by dividing the top and bottom by 3
-9/3 = -3
12 /3 = 4
-9/12 = -3/4
Answer:
see below
Step-by-step explanation:
1/12 - 5/6 = -9/12
1st, we need to identify the Least Common Multiplier of 12 and 6
in this case, the LCM is 12
for 5/6 = (5*2) / (6*2) = 10/12
2nd, adjust the fractions based on the LCM
= 1 / 12 - 10 / 12
= 1 - 10 / 12
= -9 / 12 ---- simplify -3 / 4

A factory produces 42,000 computer monitors per day. The manager of the factory claims that fewer than 660 defective computer monitors are produced each day. In a random sample of 240 computer monitors, there are 2 defective computer monitors. Determine whether the manager's claim is likely to be true. Explain.
Answer:
The manager's claim is likely to be true.Step-by-step explanation:
We are given that the factory produces 42,000 computer monitors per day
And the claim is of this amount produces fewer than 660 are defective.
a random sample shows that of 240 monitors 2 are defective
to verify the factory managers claim we need to know how many 240s are there in 42000
=42000/240= 175
Since each 240 will give 2 defective monitors
175 will give= 175*2= 350
350 is less than 660 hence the managers claim is correct

Ill give 40 points to brainliest (in each word problem write the independent and dependent variable) A.You work part time at a grocery store and are saving money for a car. You already have $200 saved and you earn $12 per hour.B.You are driving on a road trip with your friends. You have 12 gallons of gas in your car and you use 0.10 gallons each mile you drive.C.You got a 60 on your test. You test grade will improve 2 points with each extra credit assignment you turn in.
Part A
independent variable = number of hoursdependent variable = total amount savedThe equation would be y = 12x+200 where x is the number of hours and y is the amount saved. The 200 is what you already have, and then you add on 12x additional dollars.
==============================================
Part B
independent variable = number of miles you drivedependent variable = amount of gas in the carequation would be y = -0.10x+12. You start off with 12 gallons and each time you use up 0.10 gallons of gas for each mile you drive, so in total you use up 0.10x gallons
==============================================
Part C
independent variable = number of extra credit assignments turned independent variable = test gradeEquation is y = 2x+60. You add on 2x additional points to the 60 you already have
==============================================
Part D
independent variable = number of text messages sentdependent variable = total monthly billx is the number of messages and y is the total monthly bill, so the equation would be y = 0.25x + 35
==============================================
Part E
independent variable = number of cookies eaten per daydependent variable = total caloric intake per dayeating x cookies, at 120 calories a piece, means y = 120x is the total number of calories you consume per day. This is just considering the cookies of course and not other meals.
==============================================
In each case, the independent variable is the variable that is allowed to change and you know this value (or are given it). For instance, you know how many miles you drive and it varies. The dependent variable relies on the value chosen for the independent variable. So as x changes, then so does y.
Answers & Step-by-step explanation:
Let's define the two terms that we need to identify:
Independent variable: A variable that you have control over.
Dependent variable: A variable you cannot control and depends on other factors.
Let's solve your problems!

I AM ALWAYS HAPPY TO HELP :)y =6x-15
Please help
Answer:
y=15+-6x
Step-by-step explanation:
y = -6x + 15
Reorder the terms:
y = 15 + -6x
Solving
y = 15 + -6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 15 + -6x
Step-by-step explanation:
[tex]6x - 15 = y \\ 6x = y + 15 \\ \frac{6x}{6} = \frac{y + 15}{6} \\ x = \frac{y + 15}{6} \\ x = \frac{y}{6} + \frac{5}{2} [/tex]
Please help. If CJ=8x+5 CT=55, and JT=4x+2 Find JT
Answer:
- 56
Step-by-step explanation:
JT = CJ + CT
4x + 2 = 8x + 5 + 55
4x + 2 = 8x + 60
4x - 8x = 60 - 2
- 4x = 58
x = 58/-4
x = -29/2
x = - 14.5
JT = 4x + 2 = 4(-14.5) + 2 = - 58 + 2 = - 56
