Answer:c
Step-by-step explanation:
A rectangular auditorium seats 1564 people. The number of seats in each row exceeds the number of rows by 12. Find the number of seats in each row
Answer:
# of rows: 34
# of seats in each row: 46
Step-by-step explanation:
r - # of rows
s - # of seats in each row
r * s = 1564
s = r + 12
(34) * (46) = 1564
(46) = (34) + 12
Hope this helps!
3 3/8- 9/8 give your answer as a mixed number
Answer:
2 1/4
Step-by-step explanation:
We have to make the first value into an improper fraction, which makes 3 3/8 into 27/8. Now we subtract 9 from 27, giving us 18. This 18 is still over the common denominator of 8. 8 goes into 18 twice with 2 left over. So we have our mixed number as 2 2/8, which can be simplified to 2 1/4.
Lana and Jeff each randomly surveyed 15 students about their favorite types of movies. Are these samples representative of the school population? Explain.
No, the samples are not large enough to be representative.
Yes, both samples are random, so they are representative.
No, the samples might include some of the same people, so they are not representative.
Yes, the samples do not include the same people, so they are representative.
Answer:
D but see below.
Step-by-step explanation:
This question is badly thought out. 15 might be enough to be representative if the school only contains about 100 people.If B is true then it would be the answer.If D was true, it would be the answer. If C was true, it could be the same answer.So you have a question that has no clear answer. If Jeff took grade 11 and Lana took grade 12, that would make the answer much clearer. At least there would be no duplicates.
If you could refine the question a little more, you might get a clearer answer. I don't think this question should be asked and I sure don't think you should try and give an answer.
However that's not how schools work. So I would pick D, but by some bizarre method, the asker (like edge) might think of a way to make A B or C true.
What is the distance between the points (2, -3) and (-6, 4) on the coordinate
plane?
A. 4.12 units
B. 3.87 units
C. 10.63 units
D. 8.06 units
Answer:
C) 10.63 units.
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
We have the two points (2, -3) and (-6, 4). Let (2, -3) be (x₁, y₁) and let (-6, 4) be (x₂, y₂). Substitute:
[tex]d=\sqrt{(-6-2)^2+(4-(-3))^2}[/tex]
Simplify:
[tex]d=\sqrt{(-8)^2+(7)^2}[/tex]
Evaluate:
[tex]d=\sqrt{64+49}=\sqrt{113}\approx10.63\text{ units}[/tex]
Our answer is C.

Jenny is taking a vacation from Florida. She travels 70 kilometers per hour for 2 hours, and 63 kilometers per hour for 5 hours. Over the 7 hours time period what was Jenny's average speed?
Answer: 65 kmh
Step-by-step explanation:
70 kmh for 2 hours = 140 km.
63 kmh for 5 hours = 315 km
140 + 315 = 455/7 total hours = 65 kmh

The quotient obtained by dividing 4x²+3x+2 will be 4x + 15 hence option (A) will be correct.
What is the equation?An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraint.
Given that
dividend = 4x²+3x+2
divider = x -3
⇒ (x - 3) / 4x²+3x+2
⇒ (x - 3) / 4x²+3x+2
→ First it will goes for 4x time so 4x × (x - 3) = 4x² - 12x
Quotient = 4x
so (4x²+3x+2) - ( 4x² - 12x ) = 15x + 2
(x - 3) / 4x²+3x+2
→ Second time it goes for 15 so 15 × (x - 3) = 15x -45
Quotient = 15
so (15x + 2 ) - ( 15x -45 ) = 47
Hence, 47 will be the remainder and the quotient will be (4x + 15).

Find the measure of the indicated angle to the nearest degree.
Please provide an explanation, I’m trying to learn.
Answer:
B =53.15010235
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan B = 20 /15
Take the inverse tan of each side
tan ^ -1 ( tan B) = tan ^-1( 20/15)
B =53.15010235

The perimeter of the triangle below is 80 units. Find the length of side PR
Answer:
32
Step-by-step explanation:
The perimeter is equal to sum of side lengths
4x + z + 3 + 5z - 3 = 80 add like terms
10z = 80 divide both sides by 10
z = 8 PR is 4z so 8*4 = 32
What’s the slope and equation
Answer:
slope = -5 equation= y=-5x+100
Step-by-step explanation:
pick the x and y intercepts as your points to find the gradient that is
(20,0) and (0,100)
slope =∆y/∆x
=100/-20
= -5
take point(20,0) and (x,y) to find equation using the slope
equation becomes y= -5x+100

A person had $17,000 invested in to accounts One paying 7% simple interest And one paying 8% simple interest. How much was invested In each account if the interest rate after one year is $1356?
Answer:
A1 7% = $400 & A2 8% = $16,600
Step-by-step explanation:
A1 * 7% + A2 * 8% = 1356
A1 + A2 = 17000
A1 = 17000 - A2
(17000 - A2) * 0.07 + A2 * 0.08 = 1356
1190 - 0.07 A2 + 0.08 A2 = 1356
1190 + 0.01 A2 = 1356
0.01 A2 = 166
A2 = 16600
A1 = 17000 - A2
A1 = 17000 - 16600
A1 = 400
find the y-cordinates of the points that are 10 units away from the point (7,6) that have a x-cordinate of -1
Answer:
y = {0 , 12}, x = -1
point 1 (-1, 0)
point 2 (-1, 12)
Step-by-step explanation:
use the distance formula
d² = (∆x)² + (∆y)²
-----------------------------
10 units away from the point (7,6)
x-cordinate of -1
10² = (-1 - 7)² + (y - 6)²
100 = 64 + (y - 6)²
Subtract 64 from both sides
36 = (y - 6)²
Take the square root of both sides
±6 = y - 6
Add 6 to both sides
y = {0 , 12}
point 1
(-1, 0)
point 2
(-1, 12)

Answer:
21.77
Step-by-step explanation:
Applying,
V = (4/3)π(R²-r²)³/²................. Equation 1
Where V = Volume of the resultant shape, R = radius of the sphere, r = radius of the hole bored, π = pie
From the question,
Given: R = 2, r = 1
Constant: π = 3.14
Substitute these values into equation 1
V = 4/3(3.14)(2²-1²)³/²
V = (12.56/3)(3)³/²
V = 4.19(5.196)
V = 21.77

Step-by-step explanation:
The top and the bottom are the same length
17 = 3x+2
Subtract 2 from each side
17-2 = 3x+2-2
15 =3x
Divide by 3
15/3 = 3x/3
5 =x
Answer:
x = 5
Step-by-step explanation:
3x + 2 = 17
3x + 2 - 2 = 17 - 2
3x = 15
3x ÷ 3 = 15 ÷ 3
x = 5
