A total of
276

tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?

Answers

Answer 1

Final answer:

The number of adult tickets sold for the school play was 92, found by setting up an equation where the number of adult tickets plus twice the number of adult tickets equals the total of 276 tickets sold.

Explanation:

Calculating the Number of Adult Tickets Sold

The student is asked to find out how many adult tickets were sold for the school play, given that a total of 276 tickets were sold and the number of student tickets was two times the number of adult tickets sold. Let's denote the number of adult tickets as x and the number of student tickets as 2x. The total number of tickets is the sum of adult and student tickets which can be represented as:

x + 2x = 276

Combining like terms, we get:

3x = 276

To find the value of x, we divide both sides by 3:

x = 276 / 3

x = 92

Therefore, the number of adult tickets sold was 92.

A cell phone uses a 3.0 V battery. The circuit board it uses needs a 0.05 A current. What size resistor is needed to generate this current?

___ Ω

Answers

Ohm's law equation used to solve this problem is;
V = IR
where V - voltage
I - current passing 
R - resistance
voltage is the potential difference between 2 points and current passing through these 2 points is proportional to the potential difference, in other words voltage.
V∞I
Resistance is the constant in the equation 
the current required to pass through is 0.05 A (amperes)
the battery voltage is 3.0 V (volts)
substituting these values 
3 V = 0.05 A * R
R = 3/0.05 
R = 60 Ω (ohms)

Answer:

the answer is 60.

Tom and Sonya were comparing their answers on a math problem. It was an order of operations problem, and they each had a different answer. Tom had an answer of 11, and Sonya had an answer of 104. Which student correctly solved the order of operations problem given by the teacher?

(52 +6)–(7•4)+8

*Challenge: Can you nd the mistake that Sonya made in completing her problem?

Answers

Order of operations is PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction)

= (52 + 6) - (7 * 4) + 8
work inside parentheses first
= 58 - 28 + 8
work left to right now
= 30 + 8
= 38

SONYA'S MISTAKE
= (52 + 6) - (7 * 4) + 8
I think she added the 52, 6+4, multiplied 7*4 to equal 28, then added the 6+8 to equal 14
= 52 + 28 + 14 + 10
= 104

ANSWER: 38

Savanna had 40 iris blooms last year. This year she had 15% more iris blooms. How many more iris blooms did Savanna have this year?

Answers

40*15%=6

40+15%=46

hope one of these helped
To solve this problem what you can do is the following rule of three:
 40 iris blooms -----> 100%
 x iris blooms -------> 115%
 Clearing the value of x we have:
 x = (115/100) * (40)
 x = 46
 Then, comparing with last year we have:
 40-46 = 6
 Answer: 
 Savanna had this year 6 more iris blooms than last year.

Point slope form is y=mx+b
M=the slope
B=the x intercept

So then the equation us y=2/5x+b
Then you solve for b by plugging in the point (-3,-6) for the x and y.
B= -36/5 or -7 1/5

Therefore the slope intercept form is y=2/5x-7 1/5
y = mx + b (this is the equation it has to fit in)
m = slope
b = y intercept
-6 = 2/5(-3) + b
-6 = -6/5 + b
b = -6 + 6/5
b = 4 4/5
-6 = 2/5(-3) + 4 4/5




using the same equation....
m = 1/3
x = 0
y = -2/5
-2/5 = 1/3(0) + b
1/3(0) = 0
-2/5 = b
y = 1/3x + -2/5

A rectangular pool is 12m long and 6m wide. A walkway of uniform width surrounds the pool. If the area of the walkway is 9m squared less than that of the pool, how wide is the walkway?

Answers

The walkway is 1.5 m wide.

The area of the pool is 12(6) = 72 m².

Adding a walkway of unknown width, x, around all 4 sides of the pool increases the width by 2x and the length by 2x; thus the area of the entire pool and walkway together would be given by

(12+2x)(6+2x)

We know that the area of just the walkway is 9 m² less than the area of the pool.  This means that:

(12+2x)(6+2x)-72 = 72-9

Multiplying through we have:
12*6+12*2x+2x*6+2x*2x - 72 = 63
72 + 24x + 12x + 4x² - 72 = 63
24x + 12x + 4x² = 63
36x + 4x² = 63

Writing in standard form we have:
4x² + 36x = 63

We want to set it equal to 0 to solve, so subtract 63 from both sides:
4x² + 36x - 63 = 63 - 63
4x² + 36x - 63 = 0

Using the quadratic formula, 

[tex]x=\frac{-b\pm \sqrt{b^2-4ac}}{2a} \\ \\=\frac{-36\pm \sqrt{36^2-4(4)(-63)}}{2(4)} \\ \\=\frac{-36\pm \sqrt{1296--1008}}{8}=\frac{-36\pm \sqrt{1296+1008}}{8} \\ \\=\frac{-36\pm \sqrt{2304}}{8}=\frac{-36\pm 48}{8}=\frac{-36+48}{8}\text{ or }\frac{-36-48}{8} \\ \\=\frac{12}{8} \text{ or }\frac{-84}{8}=1.5 \text{ or }-10.5[/tex]

Since a negative width makes no sense, the walkway is 1.5 m wide.

Alice says she can find the area of the room by dividing the floor plan into two trapezoids. show how she can divide the floor plan. then find the area using her method

Answers

To find the room's area, Alice can divide the floor plan into two trapezoids, calculate each trapezoid's area using the formula for a trapezoid's area (A = (a + b)/2 × h), and then sum the two areas.

Alice can find the area of the room by first dividing the floor plan into two trapezoids, which can be done by drawing a line across the room that connects two non-adjacent vertices. Once divided, you can use the formula for the area of a trapezoid to find the area of each part and then sum the two areas to get the total area of the room.

Calculating the Area of a Trapezoid

The formula for the area of a trapezoid is:

A = (a + b)/2 × h

Where a and b are the lengths of the two parallel sides, and h is the height. Once you calculate the area of both trapezoids using this formula, you can add them together to find the total area of the room.

Number of dinners = 125 Individual portion = 8 oz. Size of can = 32 oz. Number of cans required = _____. 2

Answers

To get total of oz for the dinner:

125 * 8 =  1000 oz

To get number of cans:

1000 ÷ 32 = 3.125 cans or at least 4 cans to served dinner

Answer:

Number of cans required = 32

Step-by-step explanation:

Number of dinners = 125

Individual portion size of each dinner = 8 oz.

Total portion size of all the dinners = 125 × 8

⇒ Total portion size of all the dinners = 1000 oz.

Size of one can = 32 oz.

[tex]\text{Number of cans required = }\frac{\text{Total portion size of dinner}}{\text{Size of each can}}\\\\\implies\text{Number of cans required = }\frac{1000}{32}\approx 31.25[/tex]

Hence, Number of cans required = 32

Now, we can set up our equation:

[tex]4x-12 = 8+2x[/tex]

We can solve for x:

Since their perimeters are equal the perimeter of the triangle is also 28 units²

To factor a trinomial, first we should factor out the GCF, or greatest common factor, shared by all of the coefficients and constants.  The greatest common factor of -3, -21, and -30 is -3, therefore, this is the number we must factor out first.

When we factor out the GCF of -3, we get:
-3(q^2 + 7q + 10)

Next, we must look for two numbers that will serve as coefficients for the variables in factored form.  These two numbers must add to 7 (the middle term) and multiply to 10 (the constant or last term).  The two numbers that satisfy these parameters are 5 and 2.

Therefore, we must use these numbers to create factors of the innermost factor that we have left, to get:

-3(q+5)(q+2)

The above expression is your final answer, because you cannot factor any more.  And remember: you can always check to make sure that your factoring is correct by multiplying out the factors and making sure you get your original trinomial.
