stadium already has 250 people in it at noon.If 35 people per minute enter the stadium,how many are in the stadium at 1:30 p.m. when a concert is supposed to begin?
Answer:
3,400 people
Step-by-step explanation:
First, find how many minutes are between noon and 1:30 pm
This is an hour and 30 minutes, so it will be 90 minutes
Then, multiply 90 by 35, since 35 people enter per minute
90(35)
= 3150
Then, add the 250 people that were already in it
3150 + 250
= 3400
So, there will be 3,400 people in the stadium
Answer:
3400
Step-by-step explanation:
250+35m=noon

the discriminant of the equation 7√3x²+10x-√3 is...... plzz i need it fast
Step-by-step explanation:
Hey there!
Here,
The equation is:
[tex]7 \sqrt{3 \: } {x}^{2} + 10x - \sqrt{3 } = 0[/tex]
Comparing the equation with ax^2+bx+c=0. We get;
[tex]a = 7 \sqrt{3} [/tex]
[tex]b = 10[/tex]
[tex]c = \sqrt{3} [/tex]
Now,
Discriminant= ?
We have,
[tex]discriminant = {b}^{2} - 4ac[/tex]
Put all values.
[tex]discriminant = {10}^{2} - 4 \times 7 \sqrt{3} \times \sqrt{3} [/tex]
[tex]discriminant = 100 - 4 \times7 \times 3[/tex]
[tex]discriminant = 100 - 84[/tex]
Therefore the discriminant = 16.

Solve for k.
12/k = 3
Answer:
k=3/12
k=.25
Step-by-step explanation:
we need to get k by itself
because 12 is over k we need to get rid of it by moving it to the other side (multiplying) because it is 12/k we need to multiply it by 1/12
This eliminates 12 and leaves us with k=3/12
Which step is the most efficient way to find the solution of x + 4 > -8? Answer choices: A: Add 4 to both sides. B: Subtract 4 from both sides and switch the inequality symbol. C: Substitute 1 for x and see if it works. D: Subtract 4 from both sides.
Answer:
d
Step-by-step explanation:
The most efficient step to finding the solution to the given inequality is, to subtract 4 from both sides. Option D is correct.
Given that,
To determine which step is the most efficient way to find the solution of x + 4 > -8.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
here,
Given inequality,
x + 4 > -8
Subtract 4 from both sides,
x + 4 - 4 > - 8 - 4
x > -12
Thus, the most efficient step to finding the solution to the given inequality is, to subtract 4 from both sides. Option D is correct.

y varies directly with x, and y=24 when x=-15. what is x when y=16? a) 10 b) -22.5 c) -10 d) -25.6
Answer:
c
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 24 when x = - 15, then
24 = - 15k ( divide both sides by - 15 )
k = [tex]\frac{24}{-15}[/tex] = - [tex]\frac{8}{5}[/tex] = - 1.6 , thus
y = - 1.6x ← equation of variation
When y = 16, then
16 = - 1.6x ( divide both sides by - 1.6 )
x = - 10 → c

If -2 and 3 are zeroes of quadratic polynomial xsquare + (a+1)x+b then find the value of and b
Answer:
a = - 2, b = - 6
Step-by-step explanation:
Substitute the values of the zeros into the polynomial and equate to zero.
x² +(a + 1)x + b
x = - 2 → (- 2)² - 2(a + 1) + b = 0 , that is
4 - 2a - 2 + b = 0
2 - 2a + b = 0 ( subtract 2 from both sides )
- 2a + b = - 2 → (1)
x = 3 → 3² + 3(a + 1) + b = 0, that is
9 + 3a + 3 + b = 0
12 + 3a + b = 0 ( subtract 12 from both sides )
3a + b = - 12 → (2)
Subtract (1) from (2) term by term to eliminate b
5a = - 10 ( divide both sides by 5 )
a = - 2
Substitute a = - 2 into either of the 2 equations and evaluate for b
Substituting into (2)
3(- 2) + b = - 12
- 6 + b = - 12 ( add 6 to both sides )
b = - 6
Thus a = - 2 and b = - 6
Poonam is five times as old as Shalini. The sum of their ages is 72
Answer:
Shalini = 12
Poonam = 60
Step-by-step explanation:
Let p = poonams age
Let s = shalini's age
p = 5s
p+s = 72
Substitute the first equation into the second equation
5s+s = 72
Combine like terms
6s= 72
Divide by 6
6s/6 = 72/6
s = 12
p = 5s =5*12 = 60
Shalini = 12
Poonam = 60

Find the first four terms of the sequence using the recursive formula.
Answer:
- 3, - 11, - 35, - 107
Step-by-step explanation:
Using the recursive formula with f(1) = - 3 , then
f(2) = - 2 + 3f(1) = - 2 + 3(- 3) = - 2 - 9 = - 11
f(3) = - 2 + 3f(2) = - 2 + 3(- 11) = - 2 - 33 = - 35
f(4) = - 2 + 3f(3) = - 2 + 3(- 35) = - 2 - 105 = - 107
Thus the first four terms are
- 3, - 11, - 35, - 107

Write the slope-intercept form of the given line. Include your work in your final answer. Type your answer in the box provided to submit your solution.
Answer:
y = -3 ÷ 2x - 3
Step-by-step explanation:
As it can be seen that the line is passed by y-axis at -3.
Now we have to determine the slope
For this, use the following formula
= (x2 - x1) ÷ (y2 - y1)
At
(-2, 0), (0, -3)
So,
= (-3-0) ÷ (0+2)
= -3 ÷ 2
Now
Put in the following equation
y = mx + b.
where,
m = slope
b = y-intercept
So,
y = -3 ÷ 2x - 3

Can someone help me ASAP pleaseee
Answer:
y = 8x - 26
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, - 2) and (x₂, y₂ ) = (4, 6)
m = [tex]\frac{6+2}{4-3}[/tex] = 8 , thus
y = 8x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (4, 6) , then
6 = 32 + c ⇒ c = 6 - 32 = - 26
y = 8x - 26 ← equation of line
5. If x^1/2 =8, what is the value of x?
