Answer:
No solution.
Step-by-step explanation:
y + 3x - 4y = 0 + 0.75x
- 3y + 3x = 0 + 0.75x
- 3y + 3x - 0.75x = 0 + 0.75x - 0.75x
- 3y + 2.25x = 0
Mr.Q's class is having a giveaway where his students can receive 100 classroom credits. He will pull names out of a hat and select two winners. Once a student wins, they are not eligible to win a second time. If there are 40 total people in the class, including you and your best friend.
What is the probability that both you and your best friend get the 100 classroom credits?
PLEASE SHOW WORK!!
Answer:
1/1560
Step-by-step explanation:
The chance of you winning is 1/40, since there are 40 students and you are one of those students. Since, you cannot win again once you win once, you are eliminated. This leaves us with 39 people left. The chances of your friend being chosen out of the 39 people left is 1/39. Now you must multiply 1/40 and 1/39. After multiplying, you get 1/1560.
Solve the expression below. 3/7÷2 1/2
Answer:
6/35
Step-by-step explanation:
3/7 : 2 1/2
2 1/2 = (2*2+1) / 2 = 5/2
3/7 : 5/2 = 3/7 * 2/5 = (3*2) / (7*5) = 6/35

Answer:
Step-by-step explanation:
2.96, 3, 3.48, 7, 31
Answer:
31, 7, 3.48, 3, 2.96
Step-by-step explanation:
Look at the ones value first. 31 is the highest. Then 7. Between 3 and 3.48, think of 3 as 3.00 so therefore 3.48 is higher than 3.00
If 18 percent of the beads in a bag are green, 25 percent are red and 40 percent are purple. What is the probablity of choosing a green bead then a red bead
Answer:
[tex]P(G\ then\ R)=0.045[/tex]
Step-by-step explanation:
From the question we are told that:
Percentage of Green beads [tex]P_g=18[/tex]
Percentage of Red beads [tex]P_r=18[/tex]
Percentage of Purple beads [tex]P_p=18[/tex]
Therefore
Probability of choosing a Green bead is
[tex]P(G)=0.18[/tex]
Probability of choosing a Red bead is
[tex]P(R)=0.25[/tex]
Generally the equation for choosing a green bead then a red bead is mathematically given by
Since Outcomes are independent
[tex]P(G\ then\ R)=0.18*0.25[/tex]
[tex]P(G\ then\ R)=0.045[/tex]
An account with an initial balance of $5000 earns 5% interest for 3.5 years.
Answer:
The investor will earn $875 over the course of 3.5 years.
Step-by-step explanation:
Sounds like simple interest (not compound interest).
The appropriate formula is i = prt, which here is
i = $5000(0.05)(3.5) = $875
The investor will earn $875 over the course of 3.5 years.

Answer:
[tex]A=54.95\ ft^2[/tex]
Step-by-step explanation:
The angle of shaded sector = 360-332 = 28°
The radius of sector, r = 15 ft
We need to find the area of the shaded sector. The formula for the area of the sector is given by :
[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\=\dfrac{28}{360}\times 3.14\times (15)^2\\\\A=54.95\ ft^2[/tex]
So, the area of the shaded sector is equal to [tex]54.95\ ft^2[/tex].

A.2,000 liters
B.200 liters
C.2 liters
D. 20 liters
The best estimate for a kitchen sink is 20 liters from the options given.
Option C is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The average capacity of a kitchen sink = 32 liters.
The best estimate for the capacity of a kitchen sink.
= 20 liters to 40 liters
Thus,
20 liters can be our best estimate.

Answer:
1332.8 ft^3
Step-by-step explanation:
separate the two figures into a flat cylinder and a flat box
Volume of a cylinder= [tex]\pi r^{2} h[/tex]
where radius= 3ft and height= 3ft
therefore
[tex]=\pi (3)^{2} (3) \\= 84.8 ft^{3}[/tex]
now for the flat box:
volume of box= [tex]w*l*h[/tex]
where width= 6ft, length= 16ft, height= 13ft
therefore
[tex]=(6)(16)(13)\\=1248 ft^{3}[/tex]
now add the volume of the cylinder and box together
[tex]84.8 + 1248\\= 1332.8 ft^{3}[/tex]
A triangle has angle measurements of 53°, 37°, and 90°. What kind of triangle is it?
Answer and Step-by-step explanation:
This triangle is a right triangle.
- Acute angles are angles that have a degree that is less than 90 degrees.
- Obtuse angles are angles that have a degree that is more than 90 degrees.
- Right angles are angles that are 90 degrees.
It has 1 angle that is 90 degrees, so it is a right triangle.

Find the surface area of the figure below.
Answer:
261 cm²
Step-by-step explanation:
To find the surface area of a square pyramid, you must first recognize all of the shapes.
There are four triangles and one square.
To find the area of a square, multiply the side by itself twice.To find the area of a triangle, multiply the base and the height, then multiply the product by 1/2.The triangles have a base of 9 and a height of 10.
[tex]9*10=90[/tex]
Multiply the product by 1/2.
[tex]90*1/2 = 45[/tex]
There are four triangles.
[tex]45*4=180[/tex]
The area of all three triangles is 180 centimeters; the area of a single triangle is 45 centimeters.
There square has sides of 9 centimeters.
[tex]9*9=81[/tex]
The area of the square is 81 centimeters.
Lastly, we add the areas of the shapes.
[tex]45+45+45+45+81 = 261.[/tex]
Therefore, the surface area of this square prism is 261 cm².
You can use this layout to find the surface area of a square pyramid.
help how do i solve for this ?
Answer:
Solution:
Given,
Radius(r) = 11 ft
C = ?
Now,
[tex]c = 2\pi \: r[/tex]
C = 2 × 3.14 × 11
= 70 cm
again,
C = 360°
angle = 315°
So,
C = 70 cm
or, 360° = 70 cm
or 1° = 70/360°
or 1° = 7/36
again ,
area = 7/36 × 315°
= 61.25 cm
