#1. a bag contains red marbles and white marbles in a ratio of 3 to 5. if one marble is drawn, what is the probability that the marble is not red?
#2. the sides of a triangle are 7in., 24in., and 25in. Is the triangle a right triangle? Justify your answer.
#3. The carpet cost $18 per square yard. Use two unit multipliers to find the cost per square foot.
#4. if the dimensions of a rectangle are increased by 100%, then the area of the rectangle is increased by what percent?
#5. The vertices of a trapezoid are at (-3,-2), (5,-2), )2,3), and (-2,3). What is the area of the trapezoide?
#6. √6 · √12
Answer:
#1: 5/8, #2: It is a right triangle, #3 $2: per square foot, #4: 300%
Step-by-step explanation:
#1: If you want the probability of drawing a non-red marble, you need to have the number of non-red marbles divided by the total number of marbles. Since it's a 3 to 5 ratio, and the 5 represents marbles that are white, not red, you can put 5/(5+3), or 5/8 as your answer.
#2: For this one, you need to use the pythagorean theorem, a rule that will be true if it's a right triangle, and false if it's not. It's A² + B² = C², where C is bigger than A and B. To apply this, you can plug 7² + 24² into a calculator, and see whether or not the answer is equal to 25² (which, in this case, it is, meaning that it is a right triangle.)
#3: The idea with this is cancelling out the units until you end up with the units you want. You know how 7897/7897 would still be equal to one, as anything divided by itself is still one? We can use that concept, because multiplying our original value by 1 won't change the value, just the units. Since 1 yard = 3 feet, we can do this: ($18)/(yard²) × (1 yard)/(3 feet) × (1 yard)/(3 feet) = $2/feet²
#4 This one I will use sample values for: let's say our rectangle has a length of 10 inches and a width of 20 inches. That means it's area will be L × W, that is, 10 × 20 = 200 inches². Now lets increase the dimensions by 100%. Our length would become 20 inches, and our width would become 40 inches. That makes L × W = 20 × 40 = 800 inches². Now, to see what percent increase that is from the original, we have to do (800 - 200)/200, that is, 3, or 300%.
Sorry I don't have time to do the last one, but might I suggest that you post the questions individually next time? I just think it might make people less scared to jump into solving one problem than five, so you might get answers sooner =)
The area of a room is represented by the trinomial 3x^2-x-10. If the width of the area is represented by x-2, find the expression that represents the length of the room
Answer:
l = (3x+5)
Step-by-step explanation:
Given that,
The area of a room, [tex]A=3x^2-x-10[/tex]
The width of the room, [tex]b=(x-2)[/tex]
We need to find the length of the room.
The area of the room is given by :
A = lb
[tex]l=\dfrac{A}{b}\\\\l=\dfrac{3x^2-x-10}{x-2}\\\\l=\dfrac{(x-2)(3x+5)}{x-2}\\\\l=(3x+5)[/tex]
So, the length of the room is equal to (3x+5).

The area of the surface of an office desk is 10 square feet. The perimeter is 14 feet. What are the dimensions of the desk?
Answer:
5ft and 2ft
Step-by-step explanation:
Area = bh or lw
Perimeter = 2(l) + 2(w)
Find factors of 10: 1, 2, 5, 10
1 and 10 is not right because Perimeter would be too big and not equal 14)

Mrs. Sanchez promised each of her 35 fifth grade students one fourth of a pie for Pi Day (March 14th). There are 6 pies left at Costco. Does she have enough for her 35 students? Explain how you know. If she doesn't have enough, how many more pies does she need?
Answer: No, she needs 3 more pies.
Step-by-step explanation:
Hi, no she does not have enough pie, you would know by multiplying the amount of pies she has by 4, as she promised to give them 1/4 of a pie each, leaving her to only have 24 pieces in toShe would need at least 9 pies to have enough for all 35 students, plus an additional 1/4 sized slice left over.
given that sin(x+4)=cos(3x)find tan(x+40)to 4 s.f.
Answer:
[tex]\tan(x + 40) = 1.842[/tex]
Step-by-step explanation:
Given
[tex]\sin(x + 4) = \cos(3x)[/tex]
Required
Find [tex]\tan(x + 40)[/tex]
In trigonometry
If [tex]\sin(A) = \cos(B)[/tex]
Then: [tex]A + B = 90[/tex]
So, we have:
[tex]\sin(x + 4) = \cos(3x)[/tex]
[tex]3x + x + 4 = 90[/tex]
[tex]4x + 4 = 90[/tex]
Collect like terms
[tex]4x =- 4 + 90[/tex]
[tex]4x =86[/tex]
Solve for x
[tex]x = 86/4[/tex]
[tex]x = 21.5[/tex]
So:
[tex]\tan(x + 40) = \tan(21.5+40)[/tex]
[tex]\tan(x + 40) = \tan(61.5)[/tex]
Using a calculator:
[tex]\tan(x + 40) = 1.842[/tex]

If using the method of completing the square to solve the quadratic equation x^2-9x+2=0x 2 −9x+2=0, which number would have to be added to "complete the square"?
Answer:
The number to be added is 81/4
Step-by-step explanation:
To get the number, we look at the coefficient of x
In this case, we have it as -9
we divide this by 2
It gives (-9/2)
We square this value and add it to both sides
This would be
(-9/2)^2 = 81/4
It is this number we will add to both sides of the equation
Three bells, A,B and C toll every 5 seconds, 8 seconds and 12 seconds respectively. They all start tolling together. After how many seconds will they all toll together again
Answer:
120 seconds
Step-by-step explanation:
To obtain the number of seconds they will all till together again, obtain the lowest common multiple of the three bell times :
Bell A :
Multiples of of 5 = 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125
Bell B :
Multiples of 8 = 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128
Bell C :
Multiples of 12 = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132
From the values above, the lowest common multiple is 120, Hence, they'll toll together again after 120 seconds
Use the distributive property to expand -4 (-2+3x). Which is an equivalent expression?
-8/5 + 12x
-8/5 - 12x
8/5 + 12x
8/5 - 12x
Answer:
The answer should be 8-12x......if i take a wild guess out of your answer choices, would say C.
Step-by-step explanation:
-4 (-2+3x)
[carry over the -4 to (-2) and (3x) ]
8-12x

C.) The height increases at a constant rate of change.E
Step-by-step explanation:
Edge 2022
The function is linear and the height increases at a constant rate of change are the correct statements of the given graph.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Based on the description, it seems that the function is linear because the graph shows a line of dots that increases at a constant rate from 0 to 9 weeks.
Therefore, the following statements apply:
The function is linear.
The height increases at a constant rate of change.
Linear functions are those functions whose graph goes in a straight line. This function has one independent variable and one dependent variable.
The height increases at a constant rate of change. We can see as the time is increasing the height is increasing. We can determine this by slope of graph.
Hence, the function is linear and the height increases at a constant rate of change are the correct statements of the given graph.

3(g + 4) = 9
Need help
Answer:
g=-1
Step-by-step explanation:
3(g+4)=9
Divide both sides by 3.
g+4= 9/3
Divide 9 by 3 to get 3.
g+4=3
Subtract 4 from both sides.
g=3−4
Subtract 4 from 3 to get −1.
g=−1
Answer:
3(g+4)=9
or, 3(g+4)/3=9/3 [Dividing both sides by 3.]
or, g+4=3
or, g+4-4=3-4 [Subtracting 4 from both sides.]
So, g=-1

Dylan wants to buy a new guitar. He borrows the money he needs and pays an equal amount back for 11 months. The interest is $3 each month. How much money will he pay in interest?
Answer:
Total interest paid= $33
Step-by-step explanation:
Giving the following information:
Number of periods= 11 months
Interest per month= $3
To calculate the total amount of interest paid, we need to use the following formula:
Total interest paid= number of periods*interest per period
Total interest paid= 11*3
Total interest paid= $33
